History UnresolvedSexualTension / LiveActionTV

* ''{{Series/Salem}}'': It's implied that Mary still has feelings for John Alden, and is torn between her allegiance to the witches' cause and said feelings. Anne also appears to have a budding crush on him as well.

* '¨Series/{{Cranford}}'': The tension between Laurentia Galindo and Mr Carter smokes up the screen. She's a Baronet's daughter from an impoverished family and earns her living as a milliner, but still is on visiting terms with Lady Ludlow. He's Lady Ludlow's land agent. It stays unresolved because AnyoneCanDie on this show.

** Buffy and Angel. As of Season 9, Buffy/Angel has been all but [[ShipSinking sunk]].

* ''Series/{{Glee}}'': Played this between Will and Emma in the first season (though, ironically, once they'd gotten together they broke up because she was too mysophobic to have sex). In the second season, the major UST is between Kurt and Blaine. Kurt [[AnchoredShip swears they're just friends]], but try telling that to audiences after their duet of "Baby, It's Cold Outside".
** And it was FINALLY resolved in "Original Songs." [[spoiler: [[TheyDo THEY DO]], [[ThisIsForEmphasisBitch BITCHES]].]]

* ''Series/{{Sherlock}}'': Sherlock and John seems to have a lot of these. A ''lot'' of this in ''A Scandal In Belgravia'' between Irene Adler and the eponymous Sherlock, though it doesn't go anywhere.

** "Cloak": The scene where Ziva and Tony are fighting the Marines is a perfect example of how she has feelings for him. Ziva hears a gun go off, [[BerserkButton she turns to see Tony on the floor]] -- and [[RoaringRampageOfRevenge and she starts to tear through the leathernecks]] in a manner that [[Series/{{Firefly}} River Tam would have been impressed with.]]

* ''Series/{{Castle}}'': This is the entire point, which has been described as "''Moonlighting'' meets ''Murder She Wrote''". More {{belligerent|SexualTension}} in the first season, but after some CharacterDevelopment settled into a serious case of this. It doesn't help that Castle's a flirt and Beckett's a tease. Resolved as of the Season 4 finale.

** Niles and Daphne, in one of the most drawn-out examples, with some absolutely brutal {{Moment Killer}}s and a plethora of [[RomanticFalseLead Paolos]]. Opinion is mixed on the effect of them getting together on the last seasons of the show. It ran for four more years thereafter, and even after they did get together, it took them almost an entire season to consummate. Of the four seasons, they were married for two.

* ''Series/ThirtyRock'': Undeniably, Jack and Liz, no matter how much Creator/TinaFey says [[NoHuggingNoKissing it's not going to happen]].

* ''Series/AshesToAshes'': Gene and Alex have been dancing around the will-they-won't-they issue since the first episode of the show, the whole police force already thinks they're shagging, and the writers have ramped up the tension even more drastically in the second series. Of course, any potential relationship between the two may be seriously hampered by the fact that Alex is quite probably trapped in her own head and Gene himself is quite possibly imaginary...
** Pretty darn resolved as of the [[GrandFinale series finale]]: [[spoiler: There's feelings there, but Gene, as the guardian of Dead Copper Purgatory, can never move on when there's new coppers to help, and it's time for Alex to "cross over". They do kiss before Alex walks into the Railway Arms.]]

* ''Series/TheBigBangTheory'': Half of the relationship of Sheldon and Amy is defined by intellectual affinity, the other half defines UST.

* ''Series/BuffyTheVampireSlayer'': Buffy and Spike for most of the series. Also Buffy and Angel. Basically anything that breathes. Or doesn't.
** As of Season 9, Buffy/Angel has been all but [[ShipSinking sunk]]. Buffy and Spike, meanwhile, are having their [[UnresolvedSexualTension UST]] amped UpToEleven.
** Also between Buffy and Xander, especially in the second half of season two, although it largely went away as the series went on.

* ''Series/{{Castle}}'': This is the entire point, which has been described as "''Moonlighting'' meets ''Murder She Wrote''". More {{belligerent|SexualTension}} in the first season, but after some CharacterDevelopment settled into a serious case of this. It doesn't help that [[TheCharmer Castle's a flirt]] and [[FetishFuel Beckett's a tease]]. Resolved as of the Season 4 finale.

** UST is also present with Warrick and Catherine.

** Also the Doctor and Romana II in the 1979-1980 era, due to real life bleeding into the production as Tom Baker and Lalla Ward were dating (and married a few weeks after she left the series). It's been noted that you can tell when Tom and Lalla had had a fight (and they even broke up briefly at one point) by how the Doctor and Romana interact on screen.
** Tension has also been noted between the Fifth and Sixth Doctors and Peri, which is generally accomplished by Peri simply walking into the room.

* ''Series/{{Dollhouse}}'': Head Adelle Dewitt and her [[NumberTwo head of security]] Laurence Dominic ooze UST during their morally grey [[PowerWalk power walks]]. At least, until: [[spoiler: he was revealed to be a spy. She sounds a ''lot'' like a jilted lover when chewing him out.]]\\
\\
Also Topher and Dr. Saunders, at least until the arrival of Bennett.
* ''Series/{{Eureka}}'': Carter and Allison. Everytime it seems to make progress the ResetButton gets mashed handily.
** Not as of the season 4 finale. Carter and Allison are still together (though more time travel was still involved to keep Allison alive)

* ''Series/{{Frasier}}'': Niles and Daphne, in one of the most drawn-out examples, with some absolutely brutal {{Moment Killer}}s and a plethora of [[RomanticFalseLead Paolos]]. Opinion is mixed on the effect of them getting together on the last seasons of the show. It ran for four more years thereafter, and even after they did get together, it took them almost an entire season to consummate. Of the four seasons, they were married for two.

* ''Series/TheMentalist'': Has Wayne Rigsby and Grace Van Pelt. At least once per episode there is some mention that one of them is attracted to the other one, and they've actually kissed once while he was under hypnosis. This doesn't look to get resolved any time soon, either: workplace rules prohibit them from dating.
** [[spoiler: Now Resolved... at least until their bosses find out.]]
*** [[spoiler: Rigsby and Van Pelt got found out and it led to their breakup. Rigsby still loves Van Pelt, she started dating a new guy. They get engaged, but then the new guy turns out to be a {{Mook|s}} for [[BigBad Red John]], and is shot. So, back to square one.]]
** Jane and Lisbon also have some UST, and a fair amount of ShipTease.

** The sexually unresolved yet happy ending is heartwarming. The shot of the pair watching TV to the Lemon Jelly soundtrack is possibly the CrowningMomentOfHeartwarming.
*** Additionally, the DVD complete series boxset featured a behind the scenes documentary on the show, ending with Simon and Jess standing outside the house that doubled as Daisy and Tim's flat. After they've wrapped up the documentary and thanked the fans for watching, they walk off, but the camera stays on the entrance to the house... [[spoiler:which is when we see them emerge, as Daisy and Tim, with a baby, clearly an item. [[CrowningMomentOfHeartwarming Aww.]]]]

* ''Series/TheWestWing'': Had Josh Lyman and Donna Moss. They eventually did resolve it, but they dragged it out over ''six and a half seasons,'' which made the resolution feel weird, like you expected it for so long that you stopped expecting it. A well-done case of WillTheyOrWontThey.\\
\\
Also, Sam Seaborn and about half a dozen women over the course of the series. The writers would introduce them, let Sam have four or five episodes of UST with them, and then make them disappear without any explanation whatsoever. They did this with Mallory, Ainsley Hayes, Connie Tate...\\
\\
Josh and Donna's relationship is alluded to and quasi-{{lampshade|Hanging}}d repeatedly. A few of dozens of examples:

* ''Series/XenaWarriorPrincess'': Xena and [[spoiler: Gabrielle]]. So much.
** And Xena and Ares. And Xena and Hercules (Although given that they had sex in the backdoor pilot, maybe not so unresolved?). And Xena and Iolaus. And Xena and Draco. And Xena and Borias. And Xena and Lao Ma. You get the pattern?
** Also, Gabrielle and [[spoiler: Joxer]].
* ''Series/TheXFiles'': Mulder and Scully. Almost every single episode from seasons 1-7 had ''some'' kind of UST moment. Some episodes had UST so palpable it was painful, like the neck-inspection scene of "Ice". It's insane that it took them seven years to do anything about it. Plus, those heated gazes that could shoot the temperature in the room up ten degrees. They say so much just looking at each other that at times, it makes physical contact kind of superfluous. They tend to exclude other characters in the room when they do it, so it makes everyone else feel like they're seeing something they shouldn't. It's awesome.
** It starts with the pilot, when a freaked-out Scully bangs on Mulder's door in the middle of the night, enters his room, and peels off her shirt so he can inspect the unusual marks she just noticed on her back. Granted, the moment is a little out of character (from that point on, Scully was noticeably more collected and level-headed, and also more modest), but still. Not to mention their teen-hormonal fits of lust and jealousy in Syzygy.
** To say nothing of the Diana Fowley fiasco, most people were expecting Scully to just shoot her and have done with it.
** Probably the most shining example of their UST would be the final scene of "The Unnatural" with Mulder "teaching" Scully to play baseball. Lots of touching, lots of double talk, and three little words (no, not ''those'' three little words): "Hips before hands."
----

* ''Series/ICarly'': Freddie with [[JustFriends Carly]], PlayedForLaughs throughout the first couple of seasons, before becoming more dramatic in the later seasons. Freddie risks his life to save Carly in one episode, but due to a friend who has her own [[RelationshipSabotage potential subversive reasons]], they break up, with the block being Carly needing to get rid of her hero worship before Freddie will go back to her with a clear conscience. And of course Freddie and Sam in later seasons.

* ''Series/RizzoliAndIsles'': Jane Rizzoli and Maura Isles ooze this. SomeAnvilsNeedToBeDropped; two women are ''very'' rarely the primary UST couple, and never in a police procedural (HeteronormativeCrusader meets ExecutiveMeddling), and some of us are very pleased indeed to see a ''Series/{{Bones}}''-worthy level of UST between them. [[FanYay For obvious reasons]]. It helps that one of them is [[Series/LawAndOrder Abbie Carmichael]] and the other is [[Series/{{NCIS}} Kate Todd]]. (Amusingly, fanon says BlondeRepublicanSexKitten Abbie was gay as well.)

* ''Series/TheLateLateShow'': Somewhat unusually for a talk show, the chemistry between host Creator/CraigFerguson and ''very'' frequent guest KristenBell seems to have elements of UST, especially in the episode where Bell came on slightly loopy from drinking cold medication, and addressed (and lampooned) head-on during an edition taped in France where Ferguson and Bell actually seem to have "a moment".

* ''Series/{{Torchwood}}'': Jack and Gwen. Whoever else Jack might be shagging, it's those two who've gotten the longing gazes and a certain nearly incendiary shooting lesson. It still exists by ''Children of Earth'', even though Jack and Gwen are with different people. It is probably to [[spoiler:emphasize the tragic love story]] between Jack and Ianto, as well as the happy-ending love story between Gwen and Rhys]]. Although, in commentary, John Barrowman did refer to this in reference to the scene where [[spoiler:Jack learns of Gwen's pregnancy before Rhys does]]. Their UST is highlighted again in "Series:Miracle Day".

** The 11th Doctor and River Song have ridiculous levels of UST. Which isn't surprising, considering the Timey-Wimey nature of their relationship, it's entirely possible that from River's perspective, they've, ah...''resolved'' it in her past, (and therefore his future).
** [[spoiler: Now quite firmly resolved, with only a mild stretch of the imagination regarding River's prison nights]]. On the other hand, trust the Doctor to find a way to weasel out of it next series.

* ''Series/{{Torchwood}}'': Jack and Gwen. Whoever else Jack might be shagging, it's those two who've gotten the longing gazes and a certain nearly incendiary shooting lesson.\\

Their UST is highlighted again in "Series:Miracle Day".

** One wonders if WilliamHMacy (the real life husband of FelicityHuffman, aka Dana) was cast as Sam because of the planned direction things would go between the characters, or if Sorkin played up that angle in response to the casting. Chicken and egg.

* ''AshesToAshes'': Gene and Alex have been dancing around the will-they-won't-they issue since the first episode of the show, the whole police force already thinks they're shagging, and the writers have ramped up the tension even more drastically in the second series. Of course, any potential relationship between the two may be seriously hampered by the fact that Alex is quite probably trapped in her own head and Gene himself is quite possibly imaginary...

** When Sara's back and Grissom's gone, {{Lab Rat}}s Hodges and Wendy became the main UST couple {{Lampshade|Hanging}}d in a Season 9 episode when one of their co-workers says what the rest are thinking and asks why they don't just admit to each other how they feel.[[spoiler: They do, in the "TakeThat, DarkerAndEdgier [[Series/BattlestarGalacticaReimagined Remakes]]!" episode. Hodges then transfers to another shift to ensure they don't get fired. Wendy finally plants a big one on Hodges in the "Field Mice" episode.]] Whether or not it means they will be together remains to be seen. [[spoiler: However, then Wendy leaves the series.]]

* ''Music/FlightOfTheConchords'': The Prime Minister of New Zealand and a character played by Lucy Lawless. At the end, Murray says to the Prime Minister, "[[ShoutOut Forget it,]] [[{{Chinatown}} it's New Zealandtown]]".

* ''Series/{{Moonlighting}}'': This was the whole premise of a romantic {{Dramedy}} series starring Creator/BruceWillis and Cybil Sheppard as private detectives. The whole show [[JumpTheShark jumped the shark]] in the fifth season when they finally consummated their relationship; the tension was simply gone and it become yet another sitcom. Lampshaded in the series finale, a great example of the show's frequent BreakingTheFourthWall. The two detectives come back to the office to find it being dismantled by people working for ABC; an ABC network executive tells them that viewers had enjoyed watching them fall in love, but after they'd already fallen they lost interest. [[note]]In reality the downfall of ''Moonlighting'' had a lot of other causes as well. Mostly it was the result of tons of behind-the-scenes problems that plagued the show for the duration of its run, ranging from script and episode delays to a writer's strike that struck mid-season to the declining quality of scripts to (infamously combative) lead actors who simply didn't want to continue working on the show. Bruce Willis launched his film career with ''Franchise/DieHard'' between the third and fourth seasons and Cybil Sheppard, reportedly never pleased with the long working hours, wanted more time off to spend time with her growing family.[[/note]]

* ''Series/{{Primeval}}'': Had multiple UST's going on at any point during the shows run. The most prominent being Jenny (or Claudia depending on which series you're watching) and Cutter...this is never resolved. No worries though, because Connor and Abby picked up right where they left off in series 3, just in time for the show to be canceled. Looks like the show may be UnCancelled though -- at least two new seasons have been confirmed, starting to air in 2011, so it looks like something might well come of Connor and Abby's UST after all. Especially when you consider the two of them are effectively trapped alone with only each other for company, as of the Series 3 finale.

* ''Series/{{Smallville}}'': At some point on the show, [[LoveDodecahedron everybody crushes after everybody]]. But almost [[AllLoveIsUnrequited never in pairs]]. Since half of the early crushes involve [[CreatorsPet Lana]] [[TheScrappy Lang]] and a [[MonsterOfTheWeek one-episode-appearance meteor freak]], Clark longing for Lana, and [[{{ClingyJealousGirl}} Chloe]] lusting after Clark to the point where she gets enraged and joins forces with Lionel upon seeing Clark and Lana kiss, the effectiveness of the UST depends very much on viewers liking that character (Though the Lana-stalker plots eventually fell away, Clana broke up and was buried, and Chloe eventually did mature out of her teenaged crush).
** Eventually after LoisLane joined the story, there was extremely heavy UST between Lois and Clark, starting with a NakedFirstImpression, and continuing throughout the middle seasons of the show. [[{{SuspiciouslySpecificDenial}} Both characters repeatedly and unconvincingly deny it]], but EveryoneCanSeeIt. Starting in Season 8, it gets so intense that neither Clark nor Lois can deny it any longer, and become a couple in Season 9.

Josh and Donna's relationship is alluded to and quasi-{{lampshaded}} repeatedly. A few of dozens of examples:

** In "Commencement" (4x22), Amy says to Donna, "Are you in love with Josh?" And Donna never answers, of course. It's a pristine example of {{Lampshading}}, and a metaphor for UST: the question is asked and never answered, just like the UST appears but is never resolved (or rather, not for a long while).

* ''Series/TheXFiles'': Mulder and Scully. Almost every single episode from seasons 1-7 had ''some'' kind of UST moment. Some episodes had UST that was palpable it was painful, like the neck-inspection scene of "Ice". It's insane that it took them seven years to do anything about it. Plus, those heated gazes that could shoot the temperature in the room up ten degrees. They say so much just looking at each other that at times, it makes physical contact kind of superfluous.

Granted, the moment is a little out of character (from that point on, Scully was noticeably more collected and level-headed, and also more modest), but still. And their teen-hormonal fits of lust and jealousy in Syzygy?!
** To say nothing of the Diana Fowley fiasco... was anybody else expecting Scully just to shoot her and have done with it? And to think Mulder perceived Scully's hatred of Fowley as professional distrust...yeah, right.

* ''Series/{{True Blood}}'': This show is laden with sex and sexual tension. Sookie and Bill have tension from the first episode until their initial get together early in the season, but the series most prominent UST is between Sookie and Eric from the moment they meet until their UST's resolution in season 4. Sookie and Alcide have a fair amount as well. Jason and Jessica get hot and bothered in seasons 4 and 5. Tara and Pam start and resolve their UST in season 5.

* ''Series/TheSopranos'': Used effectively in Season 4 between [[spoiler: Carmela and Furio.]] It ends painfully when [[spoiler: Furio panics about his feelings for Carmela, due to the fact that she's The Boss's wife, and moves back to Italy.]] In the season finale, it becomes an important factor in [[spoiler: Tony and Carmela's separation]].
** And of course, Tony and Dr. Melfi, who knows him ''emotionally'' perhaps better than any other woman in the series--being his therapist and all.
* ''Series/{{Farscape}}'': The UST Between John Crichton and Aeryn Sun in the beginning had its own gravitational field. Even after it was resolved, their [[SlapSlapKiss unstable relationship]] made it feel like it never really got resolved (thus averting ShippingBedDeath) until the condensed, mini-series fifth season.
* ''Series/{{Castle}}'': This is the entire point, which has been described as "''Moonlighting'' meets ''Murder She Wrote''". More {{belligerent|SexualTension}} in the first season, but after some CharacterDevelopment settled into a serious case of this. It doesn't help that [[TheCharmer Castle's a flirt]] and [[FetishFuel Beckett's a tease]]. Resolved as of the Season 4 finale.
* ''Series/{{Smallville}}'': At some point on the show, [[LoveDodecahedron everybody crushes after everybody]]. But almost [[AllLoveIsUnrequited never in pairs]]. Since half of the early crushes involve [[CreatorsPet Lana]] [[TheScrappy Lang]] and a [[MonsterOfTheWeek one-episode-appearance meteor freak]], Clark longing for Lana, and [[{{ClingyJealousGirl}} Chloe]] lusting after Clark to the point where she gets enraged and joins forces with Lionel upon seeing Clark and Lana kiss, the effectiveness of the UST depends very much on viewers liking that character (Though the Lana-stalker plots eventually fell away, Clana broke up and was buried, and Chloe eventually did mature out of her teenaged crush).
** Eventually after LoisLane joined the story, there was extremely heavy UST between Lois and Clark, starting with a NakedFirstImpression, and continuing throughout the middle seasons of the show. [[{{SuspiciouslySpecificDenial}} Both characters repeatedly and unconvincingly deny it]], but EveryoneCanSeeIt. Starting in Season 8, it gets so intense that neither Clark nor Lois can deny it any longer, and become a couple in Season 9.
* ''Series/{{Torchwood}}'': Jack and Gwen. Whoever else Jack might be shagging, it's those two who've gotten the longing gazes and a certain nearly incendiary shooting lesson.\\

Although, in commentary, John Barrowman did refer to this in reference to the scene where [[spoiler:Jack learns of Gwen's pregnancy before Rhys does]]. Their UST is highlighted again in "Series:Miracle Day".
* ''Series/DoctorWho'': The Doctor and Rose. Even in their last goodbye, it takes a clone of him to admit his feelings.
** The 11th Doctor and River Song have ridiculous levels of UST. Which isn't surprising, considering the Timey-Wimey nature of their relationship, it's entirely possible that from River's perspective, they've, ah...''resolved'' it in her past, (and therefore his future).
** [[spoiler: Now quite firmly resolved, with only a mild stretch of the imagination regarding River's prison nights]]. On the other hand, trust the Doctor to find a way to weasel out of it next series.
** Also the Doctor and Romana II in the 1979-1980 era, due to real life bleeding into the production as Tom Baker and Lalla Ward were dating (and married a few weeks after she left the series). It's been noted that you can tell when Tom and Lalla had had a fight (and they even broke up briefly at one point) by how the Doctor and Romana interact on screen.
** Tension has also been noted between the Fifth and Sixth Doctors and Peri, which is generally accomplished by Peri simply walking into the room.
** At least two cases of ''one-sided'' UST have been noted: Martha Jones wanted nothing better than to jump the Doctor's bones in "The Shakespeare Code" when they briefly shared a bed together (for sleeping only) but he'd have none of it. In "Flesh and Stone" Amy Pond - experiencing conflicting feelings over her impending marriage - attempts to seduce the Doctor.
* ''AshesToAshes'': Gene and Alex have been dancing around the will-they-won't-they issue since the first episode of the show, the whole police force already thinks they're shagging, and the writers have ramped up the tension even more drastically in the second series. Of course, any potential relationship between the two may be seriously hampered by the fact that Alex is quite probably trapped in her own head and Gene himself is quite possibly imaginary...
** Pretty darn resolved as of the [[GrandFinale series finale]]: [[spoiler: There's feelings there, but Gene, as the guardian of Dead Copper Purgatory, can never move on when there's new coppers to help, and it's time for Alex to "cross over". They do kiss before Alex walks into the Railway Arms.]]
* ''WireInTheBlood'': Tony and Carol have ''bucketloads'' of it. They share a ridiculous number of charged moments, complete with looks of longing, almost-kisses, a fair amount of jealousy and plenty of {{subtext}}.
* ''Series/DarkAngel'': Max and Logan are in a perpetual state of "string ready to snap" UST. The show hinged on it so much that the writers [[spoiler:infected Max with a retrovirus genetically targeted to kill Logan when they have skin-to-skin contact.]]
* ''Series/TheMightyBoosh'': Howard Moon and Vince Noir have this in spades. Vince is a bisexual and Howard has no luck with women, and there's an enormous amount of sexual tension between them. After several {{Almost Kiss}}es, they finally did hook up in 'Party', but only in a FakeOutMakeOut, and the show has ended without the two getting together, [[HookedUpAfterWards on screen, at least]]
** In response to fan questions, Barrett and Fielding have stated that they find the idea of Howard and Vince having any sexual relationship to be disturbing, as the two are such idiots that it just seems wrong. They ''have'' said the characters have a "kind of love" for each other, but that they don't analyze it.
** This is what the more logical fans of this pairing believe.
** Granted they've also said that they're well aware it's there and even considered having an episode where Vince and Howard thought they'd bummed and immediately stopped being funny.
* ''Series/BattlestarGalacticaReimagined'' (2003): Starbuck and Apollo have unresolved sexual tension [[spoiler: even after having sex]]. There was a whole episode with an A-plot about it, aptly named "Unfinished Business".
* ''NoahsArc'': This is Noah and Wade's driving dynamic early on before they get together [[spoiler:and when they reconnect after their break up and getting other boyfriends]].
* ''The Big Breakfast'': TheNineties breakfast show was powered by UST when Johnny Vaugn and Denise Van Outen were the two co-hosts. Even the advertising trails [[ShipTease hinted at it]] when they were rehired.
* ''Series/TheWestWing'': Had Josh Lyman and Donna Moss. They eventually did resolve it, but they dragged it out over ''six and a half seasons,'' which made the resolution feel weird, like you expected it for so long that you stopped expecting it. A well-done case of WillTheyOrWontThey.\\
\\
Also, Sam Seaborn and about half a dozen women over the course of the series. The writers would introduce them, let Sam have four or five episodes of UST with them, and then make them disappear without any explanation whatsoever. They did this with Mallory, Ainsley Hayes, Connie Tate...\\
\\
Josh and Donna's relationship is alluded to and quasi-{{lampshaded}} repeatedly. A few of dozens of examples:
** In "Seventeen People" (season 2, episode 18), Josh says "If you were in the hospital, I wouldn't stop for a beer," and Donna says, "If you were in the hospital, I wouldn't stop for red lights." And that's after Donna compared Josh to her ex-boyfriend.
** In "The Women of Qumar" (3x8) Amy asks Josh, "Are you dating your assistant?" Cuz some people think you are.
** In "Commencement" (4x22), Amy says to Donna, "Are you in love with Josh?" And Donna never answers, of course. It's a pristine example of {{Lampshading}}, and a metaphor for UST: the question is asked and never answered, just like the UST appears but is never resolved (or rather, not for a long while).
** In several episodes, their relationship is acknowledged by other cast members. They talk to Josh about him being jealous over her, and Joey Lucas addresses it in one episode. In "Gaza" (5x21), after Donna is in an accident, Leo asks Josh if he needs to go see her, and of course he does.
* ''Series/TheMentalist'': Has Wayne Rigsby and Grace Van Pelt. At least once per episode there is some mention that one of them is attracted to the other one, and they've actually kissed once while he was under hypnosis. This doesn't look to get resolved any time soon, either: workplace rules prohibit them from dating.
** [[spoiler: Now Resolved... at least until their bosses find out.]]
*** [[spoiler: Rigsby and Van Pelt got found out and it led to their breakup. Rigsby still loves Van Pelt, she started dating a new guy. They get engaged, but then the new guy turns out to be a {{Mook|s}} for [[BigBad Red John]], and is shot. So, back to square one.]]
** Jane and Lisbon also have some UST, and a fair amount of ShipTease.
* ''Series/StarTrekVoyager'': Chakotay and Janeway. Until it was abandoned for a LastMinuteHookup of Chakotay and Seven, to quite a few people's disappointment.
** B'Elanna and Tom Paris, for the first few seasons at least, before they get married.
** Then there's Seven and the Doctor. He started to become attracted to her in "Someone To Watch Over Me" and certain episodes hinted that she may have had feelings for him as well.
* ''Series/StarTrekTheOriginalSeries'':
** Well before any of its spin-offs played with the idea, this show experimented with the idea with the relationship between Captain Kirk and Yeoman Janice Rand: both had a mutual attraction to one another, but Kirk's position as Captain, and his feelings of responsibility as her commanding officer, were explicitly stated as the reasons why they ''didn't''. The episode "Miri" is as close as it got to being resolved, as Rand declares her love for him, but Kirk just can't quite do the same with her... and she's gone after the next episode.
** More than a few fans perceive Kirk's friendships with both Spock and Dr. [=McCoy=] as brimming with UST.
* ''Series/StarTrekTheNextGeneration'': Captain Picard and Doctor Crusher have UST from the very first two episodes (wherein he nearly has a stroke upon first seeing her and then again when she comes on to him while under the influence) to the last (wherein they eventually (in what may be an averted alternate future) marry, and then divorce, though she keeps his name). This gets particularly bad when they are telepathically joined in season 5, discover and openly discuss the UST, and still choose not to resolve it.
* ''Series/{{Spaced}}'': Daisy and Tim. Incredibly frustrating as the show ended because of Simon Pegg getting distracted with a movie career that came out of nowhere, just as the two seemed to be realising what the audience was rooting for since episode 1.
** The sexually unresolved yet happy ending is heartwarming. The shot of the pair watching TV to the Lemon Jelly soundtrack is possibly the CrowningMomentOfHeartwarming.
*** Additionally, the DVD complete series boxset featured a behind the scenes documentary on the show, ending with Simon and Jess standing outside the house that doubled as Daisy and Tim's flat. After they've wrapped up the documentary and thanked the fans for watching, they walk off, but the camera stays on the entrance to the house... [[spoiler:which is when we see them emerge, as Daisy and Tim, with a baby, clearly an item. [[CrowningMomentOfHeartwarming Aww.]]]]
* ''Series/{{Primeval}}'': Had multiple UST's going on at any point during the shows run. The most prominent being Jenny (or Claudia depending on which series you're watching) and Cutter...this is never resolved. No worries though, because Connor and Abby picked up right where they left off in series 3, just in time for the show to be canceled. Looks like the show may be UnCancelled though -- at least two new seasons have been confirmed, starting to air in 2011, so it looks like something might well come of Connor and Abby's UST after all. Especially when you consider the two of them are effectively trapped alone with only each other for company, as of the Series 3 finale.
* ''GossipGirl'': Done all sorts of backwards with Chuck and Blair. They ''start out'' by having sex, and have a friends-with-benefits thing going for a few episodes. ''Then'' they end up in a drawn-out UST storyline, which includes playing ''Literature/DangerousLiaisons'' type games, Chuck pretending to be Blair's boyfriend during a blackout, and generally wanting nothing more than to get together but neither willing to really be the initiator. Even lampshaded by Chuck in one episode, when he can't perform with other women thanks to his UST with Blair (the subsequent plan to use her as sexual Drano doesn't go all that well).
* ''Series/TheSarahConnorChronicles'': Has enough of this between John & Cameron to lift a blimp. [[spoiler: Semi-resolved during a scene in the final episode where John checks her power source, inside her body. It is played as losing their virginities, complete with nervousness, awkwardness, instructions ("take your hand and put it here") and reassurances ("that's good, John") and that it doesn't hurt. This charged scene is open to interpretation. It is possible Cameron is deliberately resolving the sexual tension, especially when she asks John how it feels in there and he has to reply. "Cold."]]
** Cameron is really one of those characters who has sexual tension with ''everyone''. There's tension between her and every single one of the show's lead characters, {{belligerent|SexualTension}} or otherwise. There's even some between her and Riley, and she's flat-out terrified of Cameron.
* ''Series/{{Dollhouse}}'': Head Adelle Dewitt and her [[NumberTwo head of security]] Laurence Dominic ooze UST during their morally grey [[PowerWalk power walks]]. At least, until: [[spoiler: he was revealed to be a spy. She sounds a ''lot'' like a jilted lover when chewing him out.]]\\
\\
Also Topher and Dr. Saunders, at least until the arrival of Bennett.
* ''Series/TheAvengers'': John Steed and Emma Peel. And episodes when he's there when she wakes up! Patrick Macnee once said, "Of course they're sleeping together! It doesn't mean they have to show the world!" Cue PSL.
-->'''Steed:''' All this time I've known you, and I never knew you could sew!\\
'''Emma:''' Well, our relationship hasn't been exactly domestic, has it?
* ''Series/TheFastShow'': Ted and Ralph. Virtually all of the humour in their sketches stems from the fact that [[TheWoobie Ralph]] has a crush on Ted, but is far too shy to confess his feelings, despite his constant, desperate, ''painful'' efforts to. Ted, meanwhile, is too embarrassed to admit he already knows, [[spoiler: and, according to WordOfGod, too closeted to admit he feels the same way. Until the [[LastMinuteHookup final]] [[MeadowRun episode]], at least]].
* ''Series/{{Leverage}}'': Parker and Hardison. There's been plenty of teasing, but while Hardison totally gets that there's something between them, Parker has NoSocialSkills due to her neglected background: she doesn't know how to have a relationship, so she's totally oblivious. Either that or she's teasing him.
** She's starting to realize something is going on.
-->'''Parker''': So the thing is, I think that maybe I might be having feelings, like weird feelings, for...pretzels.
-->'''Hardison''': Well, they're right here, when you want them.
** After [[spoiler: defusing the bomb]] in The Big Bang Job
-->[[spoiler:Parker: You know what I'm in the mood for? Pretzels.]]
** Hardison and Parker [[spoiler: are officially together as of "The Long Way Down Job".]]
** So do Sophie and Nate. Sophie and Nate [[spoiler: get a BedmateReveal at the end of "The San Lorenzo Job". They were both pretty drunk and Nate doesn't even remember. So they don't talk about it.]]
** Eliot had some with his [[ThePsychoRangers Psycho Rangers]] counterpart. When they first spotted each other they started imagining how their fight would go, which slowly devolved into a samurai fight daydream. The two of them were smiling every time they cut into these daydreams. At the end of the episode they are sitting in the bar showing each other scars, [[CasualKink as she is fiddling with the handcuffs]].
* ''Series/{{Warehouse 13}}'':
** Aggressively averted with Pete and Myka. When Myka was under the effects of an artifact that forced her to act on her suppressed desires. You'd expect this would lead to her kissing Pete. She punched him instead.
** Winked at with an earlier Warehouse pairing, a lot like our two agents, who actually did fall in love.
** In "Duped," Pete finally discovers that the Myka he's with is a fake when [[FakeOutMakeOut she kisses him]].
-->'''Pete:''' The real Myka would ''never'' kiss me – not if her life depended on it!
** There is a little here and there, though. For example, she admits she named the ferret Pete because "it's annoying but cute."
** Sexual tension may be averted with Myka and Pete but it's played for all it's worth Between Myka and HG.
-->'''HG''': How do you say goodbye to the one person who knows you better than anyone else?
-->'''Myka''': ''(holding back tears)'' I wish I knew.
* ''Series/{{Eureka}}'': Carter and Allison. Everytime it seems to make progress the ResetButton gets mashed handily.
** Not as of the season 4 finale. Carter and Allison are still together (though more time travel was still involved to keep Allison alive)
* ''Series/{{Eureka}}'' and ''Series/{{Warehouse 13}}'': During the {{Crossover}} of these two shows, Fargo and Claudia had a full serving of geeky sexual tension in the first half of the crossover, which looked like it would go nowhere until Claudia's boyfriend dumped her at the end of the first half. In the 2nd half, back in Eureka, they got their CrossoverShip sailing, making out after they geekily disabled a mine that would've killed them.
* ''Series/ICarly'': Freddie with [[JustFriends Carly]], PlayedForLaughs throughout the first couple of seasons, before becoming more dramatic in the later seasons. Freddie risks his life to save Carly in one episode, but due to a friend who has her own [[RelationshipSabotage potential subversive reasons]], they break up, with the block being Carly needing to get rid of her hero worship before Freddie will go back to her with a clear conscience.
* ''Series/RizzoliAndIsles'': Jane Rizzoli and Maura Isles ooze this. SomeAnvilsNeedToBeDropped; two women are ''very'' rarely the primary UST couple, and never in a police procedural (HeteronormativeCrusader meets ExecutiveMeddling), and some of us are very pleased indeed to see a ''Series/{{Bones}}''-worthy level of UST between them. [[FanYay For obvious reasons]]. It helps that one of them is [[Series/LawAndOrder Abbie Carmichael]] and the other is [[Series/{{NCIS}} Kate Todd]]. (Amusingly, fanon says BlondeRepublicanSexKitten Abbie was gay as well.)
* ''Series/{{Degrassi}}'': Plays with this whenever a pairing is not put into effect immediately. Clare and Eli's UST is certainly the most recent.
* ''Series/{{Glee}}'': Played this between Will and Emma in the first season (though, ironically, once they'd gotten together they broke up because she was too mysophobic to have sex). In the second season, the major UST is between Kurt and Blaine. Kurt [[AnchoredShip swears they're just friends]], but try telling that to audiences after their duet of "Baby, It's Cold Outside".
** And it was FINALLY resolved in "Original Songs." [[spoiler: [[TheyDo THEY DO]], [[ThisIsForEmphasisBitch BITCHES]].]]
* ''Series/TheCape'': Has some undercurrents of sexual tension between Vince and Orwell, but it doesn't come out very often.
* ''Series/SportsNight'': Has it in spades between Dana and Casey. Then later between Dana and [[FoeYay Sam]].
** One wonders if WilliamHMacy (the real life husband of FelicityHuffman, aka Dana) was cast as Sam because of the planned direction things would go between the characters, or if Sorkin played up that angle in response to the casting. Chicken and egg.
* ''Series/{{House}}'': House and every other regular character at one point or another.
* ''Series/{{Community}}'': The study group complains about this getting unbearable in the episode [[Recap/CommunityS1E23ModernWarfare Modern Warfare]]:
-->'''Abed:''' To be blunt, Jeff and Britta is no [[Series/{{Friends}} Ross and Rachel]]. Your sexual tension and lack of chemistry are putting us all on edge. Which is why, ironically - and hear this on every level - [[{{Pun}} you're keeping us from being]] ''Series/{{Friends}}''.\\
'''Britta:''' Jeff and I do not have sexual tension. We just argue all the time.\\
'''Shirley:''' Awww, just like [[Series/{{Cheers}} Sam and Diane]]! I ''hated'' Sam and Diane.
* ''Series/{{Sherlock}}'': Sherlock and John seems to have a lot of these. A ''lot'' of this in ''A Scandal In Belgravia'' between Irene Adler and the eponymous Sherlock, though it doesn't go anywhere.
* ''Series/InspectorLynley'': ''The Inspector Lynley Mysteries'' had this between Lynley and Havers - to such a degree that, in the Creator/{{PBS}} introduction to the first series' last episode[[note]]"Missing Joseph", specifically[[/note]], host DianaRigg explained quite emphatically that Lynley and Havers [[SuspiciouslySpecificDenial Couldn't Possibly Feel That Way About Each Other No Way No How]]. The sexual tension could have crushed your average linebacker, and it had only just started to heat up at that point! One wonders how she would have explained away certain scenes in "A Traitor to Memory"[[note]]that one scene at the end by the bonfire, where she puts her hand on his chest to stop him leaving and the tension is so thick you couldn't cut it even with an AbsurdlySharpBlade[[/note]], or "In Divine Proportion"[[note]]the infamous CryIntoChest that is so far beyond platonic the line isn't even visible any more[[/note]], or "One Guilty Deed"[[note]]when they dance around each other while she is in pyjamas and he is in a ''towel'', and you wonder which one of them subconsciously wants to jump the other more[[/note]], or "Word Of God"[[note]]the even-more-infamous-than-the-CryIntoChest scene in her apartment where they realise they are each other's ''reason to get up in the morning!''[[/note]]... SuspiciouslySpecificDenial, indeed!
* ''Series/{{Merlin}}'': Has this with pretty much all of its main characters at some point in time, although the most persistent/popular ones seem to be Arthur & Merlin and Arthur & Gwen. [[spoiler: Arthur and Gwen's OfficialCouple status gets firmly resolved in the series 4 finale when they get married.]]

* ''Series/GilmoreGirls'': Two obvious couples:
** Luke/Lorelai whose UST spans the entire series.
** Jess/Rory during the first half of the show. Jess is Luke's nephew and Rory Lorelai's daughter, so clearly it runs in the family.
* ''Series/{{Lost}}'':
** Jack and Kate (seasons 1-3)
** Sawyer and Kate (seasons 1-2)
** Jack and Juliet
** Charlie and Claire
** Sayid and Nadia (in flashbacks)
* ''Music/FlightOfTheConchords'': The Prime Minister of New Zealand and a character played by Lucy Lawless. At the end, Murray says to the Prime Minister, "[[ShoutOut Forget it,]] [[{{Chinatown}} it's New Zealandtown]]"

* ''Series/NorthernExposure'': Joel and Maggie. Resolved, unresolved, averted, inverted, subverted, lampshades, and every other durn thing under the sun.

* ''Series/XenaWarriorPrincess'': Xena and [[spoiler: Gabrielle]]. So much.
** And Xena and Ares. And Xena and Hercules (Although given that they had sex in the backdoor pilot, maybe not so unresolved?). And Xena and Iolaus. And Xena and Draco. And Xena and Borias. And Xena and Lao Ma. You get the pattern?
** Also, Gabrielle and [[spoiler: Joxer]].
* ''Series/BuffyTheVampireSlayer'': Buffy and Spike for most of the series. Also Buffy and Angel. Basically anything that breathes. Or doesn't.
** As of Season 9, Buffy/Angel has been all but [[ShipSinking sunk]]. Buffy and Spike, meanwhile, are having their [[UnresolvedSexualTension UST]] amped UpToEleven.
** Also between Buffy and Xander, especially in the second half of season two, although it largely went away as the series went on.

* ''Franchise/LawAndOrder'': Elsewhere in the canon, ''Series/LawAndOrderCriminalIntent'' has devoted partners Robert Goren and Alexandra Eames. The UST is finally acknowledged in one episode by Goren's brother Frank, who irritably tells Bobby to "take Eames to a motel and get it out of your system." Since Alex is Bobby's BerserkButton, you can imagine the response. This one is unusual in that it has a fairly non-sexual feel to it - they act as if they're in love with each other, but there isn't a lot of ''heat'' between them.
* ''Series/LawAndOrder'': There were also hints of this with Mike and Connie on the original series.

* ''Series/TheOfficeUS'': Pam and Jim from the American version of . A lot of critical speculation said that its resolution would destroy the show. Its continuing strength even after dealing with the UST is a testament to the writing team.

* ''Series/{{Sliders}}'': Being a {{Genre Blind|ness}} ChickMagnet, Quinn has this with both female regulars as well as any GirlOfTheWeek. Ironically, Quinn is eventually replaced by his AlternateUniverse counterpart, who seeks girls a lot more actively but doesn't have ''nearly'' the same luck as the other Quinn, who wasn't really looking.
* ''Series/StargateSG1'': O'Neill and Carter are the epitome of this. Behind-the-scenes forces make any romantic feelings between them ''genuinely'' appear and disappear at apparent random (as opposed to WillTheyOrWontThey). Nonetheless, it showed up least once a season. It's so obvious it hurts. Them being married in at least one AU doesn't help. And kissing. WordOfGod votes in favor of the romance. The producer stated in an interview that while it was never presented officially on the show, "in my mind, they got together [after O'Neill retired] and have been together ever since." A deleted scene from one episode ''strongly'' suggests that O'Neill and Carter finally got their resolution on.
** After O'Neill left the show, Daniel and Vala took over the job of teasing the audience about the potential of their relationship, though it was less heavy-handed in that case. Well, at least until [[spoiler:they got together in a timeline that ended up being reset]].
** Daniel and Janet had it as well. This was notable because the writers themselves didn't plan it. Daniel and Janet's actors made a conscious decision to throw it into their scenes together quite deliberately to give the fandom something to talk about, and the show's director let them do it. It did get the fandom talking about it.
* ''Series/StargateAtlantis'': Sheppard and Weir provide the UST. Until Weir leaves the show in the fourth season premier, that is.
* ''Series/TheXFiles'': Mulder and Scully. Almost every single episode from seasons 1-7 had ''some'' kind of UST moment. Some episodes had UST that was palpable it was painful, like the neck-inspection scene of "Ice". It's insane that it took them seven years to do anything about it. Plus, those heated gazes that could shoot the temperature in the room up ten degrees. They say so much just looking at each other that at times, it makes physical contact kind of superfluous. They tend to exclude other characters in the room when they do it, so it makes everyone else feel like they're seeing something they shouldn't. It's awesome.
** It starts with the pilot, when a freaked-out Scully bangs on Mulder's door in the middle of the night, enters his room, and peels off her shirt so he can inspect the unusual marks she just noticed on her back. Granted, the moment is a little out of character (from that point on, Scully was noticeably more collected and level-headed, and also more modest), but still. And their teen-hormonal fits of lust and jealousy in Syzygy?!
** To say nothing of the Diana Fowley fiasco... was anybody else expecting Scully just to shoot her and have done with it? And to think Mulder perceived Scully's hatred of Fowley as professional distrust...yeah, right.
** Probably the most shining example of their UST would be the final scene of "The Unnatural" with Mulder "teaching" Scully to play baseball. Lots of touching, lots of double talk, and three little words (no, not ''those'' three little words): "Hips before hands."
* ''Series/WizardsOfWaverlyPlace'': Many fans commented on a particular, serious case with RealLife actors Selena Gomez and David Henrie, who play Alex Russo and Justin Russo. The case is serious due to the actors' strong chemistry that turned the film's heartwarming, brother-sister scenes into almost romantic, flirtatious moments. And because it's a Creator/{{Disney}} production.
* ''Series/{{Angel}}'': Angel and Cordelia and Wesley and Fred absolutely torture the audience with this for years. Both cases are finally resolved in the final season [[spoiler: with the deaths of both women. Cordelia and Angel ''never'' get to have sex, and it's unclear if Fred and Wesley ever do (she has a line while she's dying about "finally" getting him up to her bedroom, but they might have slept together at his place).]] This could fit with all the A.I deaths on this show. [[spoiler: Doyle died right after kissing Cordelia, after pining after her for his entire time on the show, Fred died only one episode after finally getting together with Wesley, and Wesley died right as he was beginning to get along with Illyria.]]
* ''Series/JonathanCreek'': Present between Maddie and Jonathan on several episodes. Refreshing in that both actors were well outside the established romantic lead type. If anything Jonathan and Carla had it worse in the fourth series. Not helped by the fact that they dated, broke up due to a silly misunderstanding, and the next time they saw each other Carla was married. Whoops.
* ''Series/QueerAsFolk'': Positively runs on the [[BuffySpeak unresolvedness]] of Stuart and Vince's relationship. They are best friends from childhood, and Vince at least has been madly in love with Stuart for years, and as the series progresses, Stuart seems to reciprocate [[JerkassWoobie in his own way]]. They kiss, dance together, hold hands, and at one point even make it as far as the bedroom before stopping the situation from progressing any further. This hesitation is implied to actually ''stem'' from their intense feelings for each other, as they both seem to feel that actually having sex would reduce their relationship to the same level as Stuart's constant one-night-stands. As of the finale [[spoiler: they appear to be in a contented quasi-romantic relationship, but whether they have actually done the deed is left ambiguous.]]

* ''Series/{{Jake20}}'': The title character and his doctor in this short-lived show. While they came close at one point to "consummating their relationship", the show was cancelled before anything could come of it. WordOfGod is that, had they been allowed to finish off the season, they would have ended up living Happily Ever After.
* ''Series/{{JAG}}'': Essentially the series spanning relationship of Harm and Mac, as half of their spats in and outside the courtroom liked to play with this. The wake of failed relationships also seemed to keep their UST alive and well, as both Harm and Mac would have a new love interest by mid-season or the start of a new season. This lasted until the final episode where they decide to finally get married.
* ''Series/{{Friends}}'': That show lived off UST, primarily that of Ross and Rachel. They would resolve it once, then something will go wrong, cue angry break up, the UST will slowly build up again over time, over and over again. When Chandler and Monica started up a sexual relationship that deepened into love, it was a relief.
* ''Series/{{Frasier}}'': Niles and Daphne, in one of the most drawn-out examples, with some absolutely brutal {{Moment Killer}}s and a plethora of [[RomanticFalseLead Paolos]]. Opinion is mixed on the effect of them getting together on the last seasons of the show. It ran for four more years thereafter, and even after they did get together, it took them almost an entire season to consummate. Of the four seasons, they were married for two.
** Frasier and Roz suffer this a bit as well, but nothing ever really comes of it.
* ''Series/ThirtyRock'': Undeniably, Jack and Liz, no matter how much Creator/TinaFey says [[NoHuggingNoKissing it's not going to happen]].
** Jack and his mother-in-law, Diana (who's around his age). Definitely not as squicky as it sounds. They began working together to bring his wife home and are highly attracted to each other.
* ''Series/SueThomasFBEye'': Sue Thomas and Jack Hudson. A few episodes plays with this, e.g. "The Newlywed Game" where the pair goes undercover as a [[UndercoverAsLovers married couple]], and "The Kiss" where Jack fakes having a affair with Sue to maintain their cover at a law office they infiltrated.
* ''Series/WhosTheBoss'': Tony and Angela -- to the point where their Dance of Denial annoyed even the secondary characters.
* ''Series/{{Psych}}'':
** Shawn and Juliet are definitely showing what looks like some UST, granted it's not the premise around which the show is built. There was a moment in season 2 where Shawn and Jules ''almost'' kissed but Jules wound up rebuking him and in season 3 Shawn was turned down for a date with the girl from the aquarium because she didn't want to ''get in the way''. Shawn and Jules FINALLY give into their feelings for each other in season 5, and start dating.
** Shawn himself has a high school potential sweetheart "The one who got away" named Abigail. They met again at their high school reunion which led to resolving a lot of their UST. But just when Abigail seemed interested in pursuing a new relationship, Juliet was in Shawn's line of sight and he clumsily but politely backs out of it. Several episodes later he decides to go for it with Abigail and just as he gets popcorn for her, Juliet tries to resolve their UST.

* ''Series/TwentyFour'': Barrels of it between Jack and Renee on the new season. WordOfGod confirms that the two will hook up in season eight. [[spoiler:[[DeathBySex With sexy results.]]]]
* ''Series/LieToMe'': Cal Lightman and Gillian Foster.

* ''Series/{{Cheers}}'': Had UST as a strong teaser between Sam and Diane. Resolved, but repeated. and averted.
* ''Series/MurdochMysteries'': Has this character dynamics with the relationship between Detective William Murdoch and their Station House's Pathologist Dr. Julia Ogden. This is made worse by the Victorian setting and the necessary restraint needed by social standards of the time, as the UST was just as strong (if not stronger) whenever their on/off relationship was actually on. [[spoiler: It was at its highest possible level during season five when Julia was ''married to another man'' but the UST was eventually resolved when her husband pulled an I Want My Beloved To Be Happy and told her to be with William. Julia and William rekindling their romance closes the season. In season 6, the tension is back as they are together but unwilling to commit adultery when Julia goes through the unavoidable scandal of her divorce.]]
* ''Series/TheThickOfIt'': Has a lot between [[MagnificentBastard Malcolm Tucker]] and Niccola Murray. Her poor relationship with her husband is alluded to frequently, whereas he sees her ''a lot'' to deal with the latest PR disaster, and shifts between giving [[BelligerentSexualTension her truly Olympian bollockings]] for some of them and showing [[PetTheDog an uncharacteristic level of sympathy for others.]]
** On the side of the Opposition, Phil and Emma's bickering has [[LampshadeHanging actually been called "sexual tension" by their boss.]]
* ''Series/TheLateLateShow'': Somewhat unusually for a talk show, the chemistry between host Creator/CraigFerguson and ''very'' frequent guest KristenBell seems to have elements of UST, especially in the episode where Bell came on slightly loopy from drinking cold medication, and addressed (and lampooned) head-on during an edition taped in France where Ferguson and Bell actually seem to have "a moment".
* ''Series/{{Scandal}}'': Abby clearly has this for Stephen in spades.
* ''Series/{{True Blood}}'': This show is laden with sex and sexual tension. Sookie and Bill have tension from the first episode until their initial get together early in the season, but the series most prominent UST is between Sookie and Eric from the moment they meet until their UST's resolution in season 4. Sookie and Alcide have a fair amount as well. Jason and Jessica get hot and bothered in seasons 4 and 5. Tara and Pam start and resolve their UST in season 5.
* ''Series/{{Deception}}'': Julian and Joanna. Roughly 17 years worth.

* Two obvious couples in ''Series/GilmoreGirls'':

* ''Series/{{Lost}}''

* ''Music/FlightOfTheConchords'' The Prime Minister of New Zealand and a character played by Lucy Lawless. At the end, Murray says to the Prime Minister, "[[ShoutOut Forget it,]] [[{{Chinatown}} it's New Zealandtown]]"
* Half of the relationship of Sheldon and Amy in ''Series/TheBigBangTheory'' is defined by intellectual affinity, the other half defines UST.
* Everywhere in ''Series/{{Bones}}''. The season four finale shows how Brennan and Booth would be if they got married -- it's really boring without the UST. WordOfGod states that Booth remembers the fantasy. Booth's present feelings might be the result of ''brain damage'' and everyone from Angela's psychic to ''his own BadassGrandpa'' is telling him to hook up with Brennan. Episode 100 reveals that ''they were attracted to each other a year before the series started'' but then had a very bad falling out. Back in the present they finally open up to each other on camera, but Bones tearfully admits she can't get rid of her doubts about relationships and Booth is tired of waiting for her to change. Resolved off-screen.
* Joel and Maggie in ''Series/NorthernExposure''. Resolved, unresolved, averted, inverted, subverted, lampshades, and every other durn thing under the sun.
* On ''Series/{{Chuck}}'', virtually every semi-regular female character except his sister has this with Chuck. In the first season, people thought there was even UST with her. And there was. [[WhatCouldHaveBeen Chuck was originally going to start the series with a girlfriend]], and when that was scrapped many of her lines were given to his sister...resulting in a sister who's somewhat creepily concerned with her adult brother's love life.

* ''Series/XenaWarriorPrincess''. Xena and [[spoiler: Gabrielle]]. So much.

* ''Series/BuffyTheVampireSlayer''. Buffy and Spike for most of the series. Also Buffy and Angel. Basically anything that breathes. Or doesn't.

* ''Series/{{Firefly}}'' - The merchanteer ''Serenity'' had several couples with UST and played with the concepts with others.

* ''Series/LawAndOrderSpecialVictimsUnit''

* Elsewhere in the ''Franchise/LawAndOrder'' canon, ''Series/LawAndOrderCriminalIntent'' has devoted partners Robert Goren and Alexandra Eames. The UST is finally acknowledged in one episode by Goren's brother Frank, who irritably tells Bobby to "take Eames to a motel and get it out of your system." Since Alex is Bobby's BerserkButton, you can imagine the response. This one is unusual in that it has a fairly non-sexual feel to it - they act as if they're in love with each other, but there isn't a lot of ''heat'' between them.
* There were also hints of this with Mike and Connie on the original ''Series/LawAndOrder'' series.
* In ''Series/LawAndOrderUK'', it's strongly implied that DS Matt Devlin and CP James Steel have feelings for CP Alesha Philips. It actually becomes fairly obvious in each man's separate, but similar reactions to the video of her rape--James seems thoroughly sickened by it and can barely stand to watch it. Matt can't watch it at all, but is clearly just as sickened by what he can still hear.
* Pam and Jim from the American version of ''Series/{{The Office|US}}''. A lot of critical speculation said that its resolution would destroy the show. Its continuing strength even after dealing with the UST is a testament to the writing team.

* Sheppard and Weir provide the UST on ''Series/StargateAtlantis''. Until Weir leaves the show in the fourth season premier, that is.
* Mulder and Scully from ''Series/TheXFiles''. Almost every single episode from seasons 1-7 had ''some'' kind of UST moment. Some episodes had UST that was palpable it was painful, like the neck-inspection scene of "Ice". It's insane that it took them seven years to do anything about it.

[[spoiler: Doyle died right after kissing Cordelia, after pining after her for his entire time on the show, Fred died only one episode after finally getting together with Wesley, and Wesley died right as he was beginning to get along with Illyria.]]
* Present between Maddie and Jonathan on several episodes of ''Series/JonathanCreek''. Refreshing in that both actors were well outside the established romantic lead type. If anything Jonathan and Carla had it worse in the fourth series. Not helped by the fact that they dated, broke up due to a silly misunderstanding, and the next time they saw each other Carla was married. Whoops.
* ''Series/QueerAsFolk'' positively runs on the [[BuffySpeak unresolvedness]] of Stuart and Vince's relationship.

As of the finale [[spoiler: they appear to be in a contented quasi-romantic relationship, but whether they have actually done the deed is left ambiguous.]]
* This was the whole premise of ''Series/{{Moonlighting}}'', a romantic {{Dramedy}} series starring Creator/BruceWillis and Cybil Sheppard as private detectives. The whole show [[JumpTheShark jumped the shark]] in the fifth season when they finally consummated their relationship; the tension was simply gone and it become yet another sitcom. Lampshaded in the series finale, a great example of the show's frequent BreakingTheFourthWall. The two detectives come back to the office to find it being dismantled by people working for ABC; an ABC network executive tells them that viewers had enjoyed watching them fall in love, but after they'd already fallen they lost interest. [[note]]In reality the downfall of ''Moonlighting'' had a lot of other causes as well. Mostly it was the result of tons of behind-the-scenes problems that plagued the show for the duration of its run, ranging from script and episode delays to a writer's strike that struck mid-season to the declining quality of scripts to (infamously combative) lead actors who simply didn't want to continue working on the show. Bruce Willis launched his film career with ''Franchise/DieHard'' between the third and fourth seasons and Cybil Sheppard, reportedly never pleased with the long working hours, wanted more time off to spend time with her growing family.[[/note]]
* The title character and his doctor in the short-lived show ''Series/{{Jake20}}''. While they came close at one point to "consummating their relationship", the show was cancelled before anything could come of it. WordOfGod is that, had they been allowed to finish off the season, they would have ended up living Happily Ever After.
* Essentially the series spanning relationship of Harm and Mac in ''Series/{{JAG}}'', as half of their spats in and outside the courtroom liked to play with this. The wake of failed relationships also seemed to keep their UST alive and well, as both Harm and Mac would have a new love interest by mid-season or the start of a new season.

They would resolve it once, then something will go wrong, cue angry break up, the UST will slowly build up again over time, over and over again. When Chandler and Monica started up a sexual relationship that deepened into love, it was a relief.
* Niles and Daphne on ''Series/{{Frasier}}'', in one of the most drawn-out examples, with some absolutely brutal {{Moment Killer}}s and a plethora of [[RomanticFalseLead Paolos]]. Opinion is mixed on the effect of them getting together on the last seasons of the show. It ran for four more years thereafter, and even after they did get together, it took them almost an entire season to consummate. Of the four seasons, they were married for two.

* Undeniably, Jack and Liz on ''Series/ThirtyRock'', no matter how much Creator/TinaFey says [[NoHuggingNoKissing it's not going to happen]].

* Sue Thomas and Jack Hudson on ''Series/SueThomasFBEye''. A few episodes plays with this, e.g. "The Newlywed Game" where the pair goes undercover as a [[UndercoverAsLovers married couple]], and "The Kiss" where Jack fakes having a affair with Sue to maintain their cover at a law office they infiltrated.
* Tony and Angela from ''Series/WhosTheBoss'' -- to the point where their Dance of Denial annoyed even the secondary characters.

* In ''Series/{{NCIS}}'', despite both characters having relationships with other people over the course of the show, [[HandsomeLech Tony]] and [[ActionGirl Ziva]] have kept up an ongoing unresolved sexual tension for seven seasons and counting. The series [[ShipTease intentionally capitalizes]] on the UST with episodes like "Under Covers", in which they are obliged to [[UndercoverAsLovers pose as married assassins]] and fake having a lot of sex in the process, and "Boxed In", in which they spend most of the episode [[LockedInAFreezer Locked in a Box]].

* Barrels of it between Jack and Renee on the new season of ''Series/TwentyFour''. WordOfGod confirms that the two will hook up in season eight. [[spoiler:[[DeathBySex With sexy results.]]]]
* Cal Lightman and Gillian Foster in ''Series/LieToMe''.
* Used effectively in Season 4 of ''Series/TheSopranos'' between [[spoiler: Carmela and Furio.]] It ends painfully when [[spoiler: Furio panics about his feelings for Carmela, due to the fact that she's The Boss's wife, and moves back to Italy.]] In the season finale, it becomes an important factor in [[spoiler: Tony and Carmela's separation]].

* ''Series/{{Farscape}}''... oh, ''Farscape''. The UST Between John Crichton and Aeryn Sun in the beginning had its own gravitational field. Even after it was resolved, their [[SlapSlapKiss unstable relationship]] made it feel like it never really got resolved (thus averting ShippingBedDeath) until the condensed, mini-series fifth season.
* This is the entire point of ''Series/{{Castle}}'', which has been described as "''Moonlighting'' meets ''Murder She Wrote''". More {{belligerent|SexualTension}} in the first season, but after some CharacterDevelopment settled into a serious case of this. It doesn't help that [[TheCharmer Castle's a flirt]] and [[FetishFuel Beckett's a tease]]. Resolved as of the Season 4 finale.
* ''Series/{{Smallville}}''. At some point on the show, [[LoveDodecahedron everybody crushes after everybody]]. But almost [[AllLoveIsUnrequited never in pairs]]. Since half of the early crushes involve [[CreatorsPet Lana]] [[TheScrappy Lang]] and a [[MonsterOfTheWeek one-episode-appearance meteor freak]], Clark longing for Lana, and [[{{ClingyJealousGirl}} Chloe]] lusting after Clark to the point where she gets enraged and joins forces with Lionel upon seeing Clark and Lana kiss, the effectiveness of the UST depends very much on viewers liking that character (Though the Lana-stalker plots eventually fell away, Clana broke up and was buried, and Chloe eventually did mature out of her teenaged crush).

* Jack and Gwen on ''Series/{{Torchwood}}''. Whoever else Jack might be shagging, it's those two who've gotten the longing gazes and a certain nearly incendiary shooting lesson.\\

It still exists byby ''Children of Earth'', even though Jack and Gwen are with different people. It is probably to [[spoiler:emphasize the tragic love story]] between Jack and Ianto, as well as the happy-ending love story between Gwen and Rhys]]. Although, in commentary, John Barrowman did refer to this in reference to the scene where [[spoiler:Jack learns of Gwen's pregnancy before Rhys does]]. Their UST is highlighted again in "Series:Miracle Day".
* The Doctor and Rose in ''Series/DoctorWho''. Even in their last goodbye, it takes a clone of him to admit his feelings.

* Gene and Alex on ''AshesToAshes'' have been dancing around the will-they-won't-they issue since the first episode of the show, the whole police force already thinks they're shagging, and the writers have ramped up the tension even more drastically in the second series. Of course, any potential relationship between the two may be seriously hampered by the fact that Alex is quite probably trapped in her own head and Gene himself is quite possibly imaginary...

* Tony and Carol on ''WireInTheBlood'' have ''bucketloads'' of it. They share a ridiculous number of charged moments, complete with looks of longing, almost-kisses, a fair amount of jealousy and plenty of {{subtext}}.
* ''Series/DarkAngel''. Max and Logan are in a perpetual state of "string ready to snap" UST. The show hinged on it so much that the writers [[spoiler:infected Max with a retrovirus genetically targeted to kill Logan when they have skin-to-skin contact.]]
* Howard Moon and Vince Noir on ''Series/TheMightyBoosh'' have this in spades. Vince is a bisexual and Howard has no luck with women, and there's an enormous amount of sexual tension between them. After several {{Almost Kiss}}es, they finally did hook up in 'Party', but only in a FakeOutMakeOut, and the show has ended without the two getting together, [[HookedUpAfterWards on screen, at least]]

* ''Series/{{Battlestar Galactica|Reimagined}}'' (2003): Starbuck and Apollo have unresolved sexual tension [[spoiler: even after having sex]]. There was a whole episode with an A-plot about it, aptly named "Unfinished Business".

* TheNineties breakfast show ''The Big Breakfast'' was powered by UST when Johnny Vaugn and Denise Van Outen were the two co-hosts. Even the advertising trails [[ShipTease hinted at it]] when they were rehired.
* ''Series/TheWestWing'' had Josh Lyman and Donna Moss. They eventually did resolve it, but they dragged it out over ''six and a half seasons,'' which made the resolution feel weird, like you expected it for so long that you stopped expecting it. A well-done case of WillTheyOrWontThey.\\

* ''Series/TheMentalist'' has Wayne Rigsby and Grace Van Pelt. At least once per episode there is some mention that one of them is attracted to the other one, and they've actually kissed once while he was under hypnosis. This doesn't look to get resolved any time soon, either: workplace rules prohibit them from dating.

* Chakotay and Janeway in ''Series/StarTrekVoyager''. Until it was abandoned for a LastMinuteHookup of Chakotay and Seven, to quite a few people's disappointment.

* Well before any of its spin-offs played with the idea, ''Series/StarTrekTheOriginalSeries'' experimented with the idea with the relationship between Captain Kirk and Yeoman Janice Rand: both had a mutual attraction to one another, but Kirk's position as Captain, and his feelings of responsibility as her commanding officer, were explicitly stated as the reasons why they ''didn't''. The episode "Miri" is as close as it got to being resolved, as Rand declares her love for him, but Kirk just can't quite do the same with her... and she's gone after the next episode.
* More than a few fans perceive Kirk's friendships with both Spock and Dr. [=McCoy=] as brimming with UST.
* Captain Picard and Doctor Crusher have UST from the very first two episodes (wherein he nearly has a stroke upon first seeing her and then again when she comes on to him while under the influence) to the last (wherein they eventually (in what may be an averted alternate future) marry, and then divorce, though she keeps his name). This gets particularly bad when they are telepathically joined in season 5, discover and openly discuss the UST, and still choose not to resolve it.
* Daisy and Tim in ''Series/{{Spaced}}''. Incredibly frustrating as the show ended because of Simon Pegg getting distracted with a movie career that came out of nowhere, just as the two seemed to be realising what the audience was rooting for since episode 1.

* ''Series/{{Primeval}}'' had multiple UST's going on at any point during the shows run. The most prominent being Jenny (or Claudia depending on which series you're watching) and Cutter...this is never resolved. No worries though, because Connor and Abby picked up right where they left off in series 3, just in time for the show to be canceled. Looks like the show may be UnCancelled though -- at least two new seasons have been confirmed, starting to air in 2011, so it looks like something might well come of Connor and Abby's UST after all. Especially when you consider the two of them are effectively trapped alone with only each other for company, as of the Series 3 finale.
* Done all sorts of backwards on ''GossipGirl'' with Chuck and Blair. They ''start out'' by having sex, and have a friends-with-benefits thing going for a few episodes. ''Then'' they end up in a drawn-out UST storyline, which includes playing ''Literature/DangerousLiaisons'' type games, Chuck pretending to be Blair's boyfriend during a blackout, and generally wanting nothing more than to get together but neither willing to really be the initiator. Even lampshaded by Chuck in one episode, when he can't perform with other women thanks to his UST with Blair (the subsequent plan to use her as sexual Drano doesn't go all that well).
* ''Series/TheSarahConnorChronicles'' has enough of this between John & Cameron to lift a blimp. [[spoiler: Semi-resolved during a scene in the final episode where John checks her power source, inside her body. It is played as losing their virginities, complete with nervousness, awkwardness, instructions ("take your hand and put it here") and reassurances ("that's good, John") and that it doesn't hurt. This charged scene is open to interpretation. It is possible Cameron is deliberately resolving the sexual tension, especially when she asks John how it feels in there and he has to reply. "Cold."]]

* ''Series/{{Dollhouse}}'' Head Adelle Dewitt and her [[NumberTwo head of security]] Laurence Dominic ooze UST during their morally grey [[PowerWalk power walks]]. At least, until: [[spoiler: he was revealed to be a spy. She sounds a ''lot'' like a jilted lover when chewing him out.]]\\

* John Steed and Emma Peel on ''Series/TheAvengers''. And episodes when he's there when she wakes up! Patrick Macnee once said, "Of course they're sleeping together! It doesn't mean they have to show the world!" Cue PSL.

* Ted and Ralph from ''Series/TheFastShow''. Virtually all of the humour in their sketches stems from the fact that [[TheWoobie Ralph]] has a crush on Ted, but is far too shy to confess his feelings, despite his constant, desperate, ''painful'' efforts to. Ted, meanwhile, is too embarrassed to admit he already knows, [[spoiler: and, according to WordOfGod, too closeted to admit he feels the same way. Until the [[LastMinuteHookup final]] [[MeadowRun episode]], at least]].
* Parker and Hardison from ''Series/{{Leverage}}''. There's been plenty of teasing, but while Hardison totally gets that there's something between them, Parker has NoSocialSkills due to her neglected background: she doesn't know how to have a relationship, so she's totally oblivious. Either that or she's teasing him.

* During the {{Crossover}} of ''Series/{{Eureka}}'' and ''Series/{{Warehouse 13}}'', Fargo and Claudia had a full serving of geeky sexual tension in the first half of the crossover, which looked like it would go nowhere until Claudia's boyfriend dumped her at the end of the first half. In the 2nd half, back in Eureka, they got their CrossoverShip sailing, making out after they geekily disabled a mine that would've killed them.
* Freddie on ''Series/ICarly'' with [[JustFriends Carly]], PlayedForLaughs throughout the first couple of seasons, before becoming more dramatic in the later seasons. Freddie risks his life to save Carly in one episode, but due to a friend who has her own [[RelationshipSabotage potential subversive reasons]], they break up, with the block being Carly needing to get rid of her hero worship before Freddie will go back to her with a clear conscience.
* Jane Rizzoli and Maura Isles of, unsurprisingly, ''Series/RizzoliAndIsles'', ooze this. SomeAnvilsNeedToBeDropped; two women are ''very'' rarely the primary UST couple, and never in a police procedural (HeteronormativeCrusader meets ExecutiveMeddling), and some of us are very pleased indeed to see a ''Series/{{Bones}}''-worthy level of UST between them. [[FanYay For obvious reasons]]. It helps that one of them is [[Series/LawAndOrder Abbie Carmichael]] and the other is [[Series/{{NCIS}} Kate Todd]]. (Amusingly, fanon says BlondeRepublicanSexKitten Abbie was gay as well.)
* ''Series/{{Degrassi}}'' plays with this whenever a pairing is not put into effect immediately. Clare and Eli's UST is certainly the most recent.
* ''Series/{{Glee}}'' played this between Will and Emma in the first season (though, ironically, once they'd gotten together they broke up because she was too mysophobic to have sex). In the second season, the major UST is between Kurt and Blaine. Kurt [[AnchoredShip swears they're just friends]], but try telling that to audiences after their duet of "Baby, It's Cold Outside".

* ''Series/TheCape'' has some undercurrents of sexual tension between Vince and Orwell, but it doesn't come out very often.
* ''Series/SportsNight'' has it in spades between Dana and Casey. Then later between Dana and [[FoeYay Sam]].

* Series/{{House}} and every other regular character at one point or another.
* The study group complains about this getting unbearable in ''Series/{{Community}}'' episode [[Recap/CommunityS1E23ModernWarfare Modern Warfare]]:

* Sherlock and John seems to have a lot of these. A ''lot'' of this in ''[[{{Series/Sherlock}} A Scandal In Belgravia]]'' between Irene Adler and the eponymous Sherlock, though it doesn't go anywhere.
* ''[[Series/InspectorLynley The Inspector Lynley Mysteries]]'' had this between Lynley and Havers - to such a degree that, in the Creator/{{PBS}} introduction to the first series' last episode[[note]]"Missing Joseph", specifically[[/note]], host DianaRigg explained quite emphatically that Lynley and Havers [[SuspiciouslySpecificDenial Couldn't Possibly Feel That Way About Each Other No Way No How]]. The sexual tension could have crushed your average linebacker, and it had only just started to heat up at that point! One wonders how she would have explained away certain scenes in "A Traitor to Memory"[[note]]that one scene at the end by the bonfire, where she puts her hand on his chest to stop him leaving and the tension is so thick you couldn't cut it even with an AbsurdlySharpBlade[[/note]], or "In Divine Proportion"[[note]]the infamous CryIntoChest that is so far beyond platonic the line isn't even visible any more[[/note]], or "One Guilty Deed"[[note]]when they dance around each other while she is in pyjamas and he is in a ''towel'', and you wonder which one of them subconsciously wants to jump the other more[[/note]], or "Word Of God"[[note]]the even-more-infamous-than-the-CryIntoChest scene in her apartment where they realise they are each other's ''reason to get up in the morning!''[[/note]]... SuspiciouslySpecificDenial, indeed!
* ''Series/{{Merlin}}'' has this with pretty much all of its main characters at some point in time, although the most persistent/popular ones seem to be Arthur & Merlin and Arthur & Gwen. [[spoiler: Arthur and Gwen's OfficialCouple status gets firmly resolved in the series 4 finale when they get married.]]
* ''Series/{{Cheers}}'' had UST as a strong teaser between Sam and Diane. Resolved, but repeated. and averted.
* ''Series/MurdochMysteries'' has this character dynamics with the relationship between Detective William Murdoch and their Station House's Pathologist Dr. Julia Ogden. This is made worse by the Victorian setting and the necessary restraint needed by social standards of the time, as the UST was just as strong (if not stronger) whenever their on/off relationship was actually on. [[spoiler: It was at its highest possible level during season five when Julia was ''married to another man'' but the UST was eventually resolved when her husband pulled an I Want My Beloved To Be Happy and told her to be with William. Julia and William rekindling their romance closes the season. In season 6, the tension is back as they are together but unwilling to commit adultery when Julia goes through the unavoidable scandal of her divorce.]]
* ''Series/TheThickOfIt'' has a lot between [[MagnificentBastard Malcolm Tucker]] and Niccola Murray. Her poor relationship with her husband is alluded to frequently, whereas he sees her ''a lot'' to deal with the latest PR disaster, and shifts between giving [[BelligerentSexualTension her truly Olympian bollockings]] for some of them and showing [[PetTheDog an uncharacteristic level of sympathy for others.]]

* ''Series/{{True Blood}}' is laden with sex and sexual tension. Sookie and Bill have tension from the first episode until their initial get together early in the season, but the series most prominent UST is between Sookie and Eric from the moment they meet until their UST's resolution in season 4. Sookie and Alcide have a fair amount as well. Jason and Jessica get hot and bothered in seasons 4 and 5. Tara and Pam start and resolve their UST in season 5.
