* ''Series/AccordingToJim'' has the season 6 episode ''The Grill II'', which is a sequel to the season 4 episode ''The Grill''.
* ''Series/{{Angel}}'' has several examples.
** In season "[[{{Recap/AngelS03E02ThatVisionThing}} That Vision Thing]]", a prisoner is freed from another dimension by Angel, who then returns [[Recap/AngelS03E06Billy four episodes]] later to cause havoc.
** Faith's return in season four may be considered this to her appearance in season 1, "[[{{Recap/AngelS01E18FiveByFive}} Five By Five]]" and "[[{{Recap/AngelS01E19Sanctuary}} Sanctuary]]".
** "[[{{Recap/AngelS03E19ThePrice}} The Price]]" from the third season shows the consequences to the gang's actions in "[[{{Recap/AngelS03E17Forgiving}} Forgiving]]", two episodes before.
* ''Series/{{Bones}}''' Gravedigger: first appearance in the second season, caught in the fourth, put on trial in the fifth.
* ''Series/BuffyTheVampireSlayer'':
** In the episode "[[{{Recap/BuffyTheVampireSlayerS3E9TheWish}} The Wish]]" the vengeance demon Anyanka creates an AlternateUniverse where vampires rule Sunnydale. By the end of the episode TheVerse is returned to normal and Anyanka is left powerless. Later that season, the episode "[[{{Recap/BuffyTheVampireSlayerS3E16Doppelgangland}} Doppelgangland]]" was driven by Anyanka's attempts to regain her powers, and maybe [[RealityWarper warp reality]] back into a vampire run hellhole while she's at it.
** "[[{{Recap/BuffyTheVampireSlayerS5E15IWasMadeToLoveYou}} I Was Made To Love You]]", an episode about Warren's robot girlfriend running amok in Sunnydale, ended with Spike getting him to build another robot. The payoff came in "[[{{Recap/BuffyTheVampireSlayerS5E18Intervention}} Intervention]]" which involved Spike's newly-built Buffy-bot on the loose in Sunnydale.
* ''Series/{{Community}}'': "Advanced Dungeons and Dragons" from Season 2 had a follow-up "Advanced Advanced Dungeons and Dragons" in Season 5. Abed notes that sequel episodes often lead to the downfall of overly-proud creators, [[BaitAndSwitchComment which gives him the resolve to do it so he can prove his superiority to them]].
* ''Series/CriminalMinds'' has ''Outfoxed'', where the UNSUB is a copycat of a killer who first appeared in ''The Fox''.
* ''Series/{{CSI}}'' did this with 'The Execution of Catherine Willows' and its sequel 'What's Eating Gilbert Grissom?" which aired a few seasons later. Both focused on the 'Blue Paint Killer', who was actually a pair of killers, though only in the end of the second ep was the whole setup explained.
** Also, there was storyline with the CreepyChild girl suspect in 'The Unsual Suspect' and 'Goodbye and Good Luck'
** CSI likes doing this with their serial killer cases...Paul Millander's storyline was spread over at least two seasons, with months of eps between them. Only the Miniature Killer's storyline episodes were relatively close together.
* ''Series/{{CSINY}}'' had a similar thing with Shane Casey, seemingly ending his case in season 3, then having him escape and start another arc in season 6.
* ''Series/DoctorWho'':
** "[[Recap/DoctorWhoS3E2MissionToTheUnknown Mission to the Unknown]]", the Dalek Cutaway, led into "[[Recap/DoctorWhoS3E4TheDaleksMasterPlan The Daleks' Master Plan]]", two serials later. The latter story also follows up "[[Recap/DoctorWhoS2E9TheTimeMeddler The Time Meddler]]" with the return of the Monk.
** "[[Recap/DoctorWhoS5E5TheWebOfFear The Web of Fear]]" is a sequel to "[[Recap/DoctorWhoS5E2TheAbominableSnowmen The Abominable Snowmen]]" featuring the return of the Great Intelligence and Professor Travers. That story got a sequel in "[[Recap/DoctorWhoS6E3TheInvasion The Invasion]]", which saw Colonel Lethbridge-Stewart promoted to Brigadier and UNIT established, plus a SuspiciouslySimilarSubstitute for Professor Travers and his daughter Ann.
** "[[Recap/DoctorWhoS8E1TerrorOfTheAutons Terror of the Autons]]" to "[[Recap/DoctorWhoS7E1SpearheadFromSpace Spearhead from Space]]".
** One notable example is "[[Recap/DoctorWhoS9E2TheCurseOfPeladon The Curse of Peladon]]" and "[[Recap/DoctorWhoS11E4TheMonsterOfPeladon The Monster of Peladon]]". They even reused the same sets.
** "[[Recap/DoctorWhoS9E3TheSeaDevils The Sea Devils]]" is a sequel to "[[Recap/DoctorWhoS7E2DoctorWhoAndTheSilurians Doctor Who and the Silurians]]", in that it established the titular monsters as cousins. "[[Recap/DoctorWhoS21E1WarriorsOfTheDeep Warriors of the Deep]]" was a sequel to both stories.
** All the Dalek stories from "[[Recap/DoctorWhoS12E4GenesisOfTheDaleks Genesis of the Daleks]]" until "[[Recap/DoctorWhoS25E1RemembranceOfTheDaleks Remembrance of the Daleks]]" follow an ongoing story involving the Doctor's conflict with Davros and set the Last Great Time War in motion.
** Creator/PeterDavison's first year had a story called "[[Recap/DoctorWhoS19E3Kinda Kinda]]", in which a plot point was a snake-like being called the Mara gaining influence over Tegan to further its goals. The next year saw the story "[[Recap/DoctorWhoS20E2Snakedance Snakedance]]", penned by the same writer, in which we learn that the Mara still has control over Tegan and possesses her once again in order to achieve physical form.
** "[[Recap/DoctorWhoS20E1ArcOfInfinity Arc of Infinity]]" is a sequel to "[[Recap/DoctorWhoS10E1TheThreeDoctors The Three Doctors]]", in that it saw the return of Omega.
** "[[Recap/DoctorWhoS22E1AttackOfTheCybermen Attack of the Cybermen]]" is a sequel to "[[Recap/DoctorWhoS21E4ResurrectionOfTheDaleks Resurrection of the Daleks]]", in that it brings back the mercenary Lytton.
** "[[Recap/DoctorWhoS22E5Timelash Timelash]]" is a sequel to an ''untelevised'' adventure the Third Doctor had with Jo.
** "[[Recap/DoctorWhoS24E1TimeAndTheRani Time and the Rani]]" to "[[Recap/DoctorWhoS22E3TheMarkOfTheRani The Mark of the Rani]]"
** "[[Recap/DoctorWhoS27E11BoomTown Boom Town]]" continues the story of a Slitheen who survived the events of "[[Recap/DoctorWhoS27E5WorldWarThree World War Three]]".
** "[[Recap/DoctorWhoS27E2TheEndOfTheWorld The End of the World]]", "[[Recap/DoctorWhoS28E1NewEarth New Earth]]" and "[[Recap/DoctorWhoS29E3Gridlock Gridlock]]" are season-apart stories loosely connected to the Face of Boe's final message to the Doctor.
** Satellite Five (and all the mess the Doctor's involvement caused) reappears in [[Recap/DoctorWhoS27E12BadWolf Bad Wolf]] / "[[Recap/DoctorWhoS27E13ThePartingOfTheWays The Parting of the Ways]]", after an assumed one-off encounter with the Mighty Jagrafess in "[[Recap/DoctorWhoS27E7TheLongGame The Long Game]]".
** While ''Series/{{Torchwood}}'' was a recurring {{Arc Word|s}} in series 2 (with the Doctor meeting a group identifying as the Torchwood Archive in "[[Recap/DoctorWhoS28E8TheImpossiblePlanet The Impossible Planet]]" / "[[Recap/DoctorWhoS28E9TheSatanPit The Satan Pit]]"), the Doctor's only direct encounters were at the founding in "[[Recap/DoctorWhoS28E2ToothAndClaw Tooth and Claw]]" and his capture by ([[spoiler:and the subsequent slaughtering of the team of by the real villains]]) Torchwood London in "Army of Ghosts".
** The Dalek episodes from "[[Recap/DoctorWhoS28E12ArmyOfGhosts Army of Ghosts]]" to "[[Recap/DoctorWhoS30E13JourneysEnd Journey's End]]" directly follow on from one another. [[spoiler:Depending on interpretation, the surviving Daleks from "[[Recap/DoctorWhoS31E3VictoryOfTheDaleks Victory of the Daleks]]" may have come from the Dalek invasion of "[[Recap/DoctorWhoS30E12TheStolenEarth The Stolen Earth]]".]] A similar use happens with Cybus Cyberman stories from "[[Recap/DoctorWhoS28E5RiseOfTheCybermen Rise of the Cybermen]]" to "[[Recap/DoctorWhoS30E14TheNextDoctor The Next Doctor]]", which, subsequently, also involves the aforementioned "Army of Ghosts".
** "[[Recap/DoctorWhoS30E17E18TheEndOfTime The End of Time]]" picks up from [[spoiler:The Master's death]] at the end of "[[Recap/DoctorWhoS29E13LastOfTheTimeLords Last of the Time Lords]]".
** Series 4, 5 and 6 have a recurring string of non-consecutive River Song episodes ("[[Recap/DoctorWhoS30E8SilenceInTheLibrary Silence in the Library]]" / "[[Recap/DoctorWhoS30E9ForestOfTheDead Forest of the Dead]]"; "[[Recap/DoctorWhoS31E4TheTimeOfAngels The Time of Angels]]" / "[[Recap/DoctorWhoS31E5FleshAndStone Flesh and Stone]]", "[[spoiler:[[Recap/DoctorWhoS31E12ThePandoricaOpens The Pandorica Opens]]" / "[[Recap/DoctorWhoS31E13TheBigBang The Big Bang]]"]]..., though from her point of view, they're prequel episodes.
** Series 5's "[[Recap/DoctorWhoS31E11TheLodger The Lodger]]", a BreatherEpisode just before the series 5 finale, was followed by series 6's "[[Recap/DoctorWhoS32E12ClosingTime Closing Time]]", a BreatherEpisode just before the series 6 finale.
** The 50th anniversary special "[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]" has two sequel multi-part episodes in Series 9 (which aired two years later):
*** "[[Recap/DoctorWhoS35E7TheZygonInvasion The Zygon Invasion]]" / "[[Recap/DoctorWhoS35E8TheZygonInversion The Zygon Inversion]]" is a sequel to the B-plot, revealing what happened to the Zygons after the Doctor foiled their scheme.
*** The finale three-parter "[[Recap/DoctorWhoS35E10FaceTheRaven Face the Raven]]"/"[[Recap/DoctorWhoS35E11HeavenSent Heaven Sent]]"/"[[Recap/DoctorWhoS35E12HellBent Hell Bent]]" is a sequel to the A-plot as [[spoiler: the Doctor returns to Gallifrey at last]]. "Face the Raven" itself doubles as a sequel to both Series 8's "Flatline", as Rigsy needs Clara and the Doctor's help once more, and "The Girl Who Died"/"The Woman Who Lived" from earlier in this season, as [[spoiler: Ashildr/Me returns]].
* In ''Series/EnemyAtTheDoor'', the first-season episode "The Jerrybag" (in which a woman gets pregnant to a German soldier and has to decide whether to keep the baby after he's reassigned and killed in action) was followed up in the second-season episode "The Right Blood" (in which the soldier's family learns about the boy and tries to convince her to give him over to them).
* In ''Series/TheFlash1990'', the episodes "The Trickster" and "Trial of the Trickster" were several episodes apart but they were combined into one two-part "movie" for VHS release.
* In ''Series/TheFlash2014'', "King Shark" is a sequel to a minor plot in "The Fury of Firestorm", this time focusing on the titular villain, whose initial appearance lasted only about a minute.
* ''Series/{{Friends}}'' : "TOW the Embryos" and "TOW All the Haste" about Rachel & Monica and Joey & Chandler switching apartments. They both even start the same, with Rachel being rudely awakened in the morning.
* ''Series/HerculesTheLegendaryJourneys'' has done this a number of times. For example, there was the episode 'King For A Day', where Iolaus has to impersonate a missing king. A season or two later came 'Long Live The King', where Iolaus has to impersonate the king again.
* ''Series/TheHauntingHour'' has Season 4's "Dead Bodies", which picks up from the end of Season 1's "The Dead Body."
* ''Series/HowIMetYourMother'': First there was "Slap Bet" where Marshall won the right to slap Barney in the face five times, as hard as he can, at any moment he chooses. Next season, we got the episode "Slapsgiving", where Marshall decides to dole out one of his slaps on [[ThanksgivingEpisode Thanksgiving Day]] and spends the whole episode putting Barney through a ParanoiaGambit. Two more years pass, and finally "Slapsgiving 2: Revenge of the Slap" arrives: it's [[ThanksgivingEpisode Thanksgiving]] again and Marshall decides to let Ted and Robin slap Barney in his place, and, once more, Barney spends the whole episode tortured by the knowledge of what's to come.
** The first season HalloweenEpisode "The Slutty Pumpkin" establishes how Ted once met a girl in a pumpkin costume at a Halloween party who he had amazing chemistry with, but lost her number and has spent every Halloween since hoping to find her again. He finally meets her for real in the seventh season episode "The Slutty Pumpkin Returns".
* ''Series/ICarly'': ''iThink They Kissed'', where Carly finds out that Sam and Freddie shared a FirstKiss is the SequelEpisode to ''iKiss'' where the FirstKiss occurred.
** "iPsycho" and "iStill Psycho" (and the ''Series/SamAndCat'' episode "#[=SuperPsycho=]").
* ''Series/ItsAlwaysSunnyInPhiladelphia'':
** "Gun Fever 2: Still Hot" (season 9) is a sequel to "Gun Fever" (season 1).
** "The Gang Makes Lethal Weapon 6" (season 9) is a sequel to "Dee Reynolds: Shaping America's Youth" (season 6).
** "The Nightman Cometh" (season 4) expands on a plot point from "Sweet Dee is Dating a Retarded Person" (season 2).
** The plot of "The Gang Finds a Dead Guy" (season 1) gets continued in "Pop-Pop: the Final Solution" (season 8).
** "The World Series Defense" (season 5) and "The Gang Gets Stranded in the Woods" (season 6) both deal with the Gang's fondness for the Philadelphia Phillies and Mac's CelebCrush on Chase Utley.
** "The Gang Gives Back" (season 2) is a sequel to "The Gang Goes Jihad", which precedes it by a couple of episodes.
* ''Series/LawAndOrder'' brought back its [[NoCelebritiesWereHarmed Not-O-J-Simpson]] character when "If I did it" was news. Keep in mind the character was from many ''seasons'' ago. Two other examples:
** "Coma" featured comedian Larry Miller as a nightclub owner whose first wife died under mysterious circumstances. He was the prime suspect until a junkie came forward and confessed to the crime. The last scene of that episode was the cops viewing a videotape where the junkie was shown to have performed at the suspect's nightclub. Two years later (in an episode called [[ExactlyWhatItSaysOnTheTin "Encore"]]), Miller's character returns after his second wife is murdered. He looks like he's able to evade justice again, but this time [[spoiler:his would be ''third wife'' is revealed to have helped screw up the investigation. The cops get her to cooperate by reminding her of what happened to the suspect's first two wives]].
** The first season episode "Indifference", is based on the [[http://en.wikipedia.org/wiki/Joel_Steinberg Joel Steinberg]] case. In that episode, [[InspiredBy not-Steinberg]] was convicted and sent to jail. Around the time the real Steinberg was released (a decade and a half later), the episode "Fixed" had the not-Steinberg character be released from jail, only to be gunned down and become the [[AssholeVictim victim]] of the story.
* In ''Series/LegendsOfTomorrow'', the season 2 episode "Outlaw Country" is a sequel to the season 1 episode "The Magnificent Eight", as the Legends return to the Old West and once again work with Jonah Hex.
* ''Series/{{Merlin}}'' has three Lancelot-centric episodes (though he appeared in a couple more) that encompass his CharacterArc: ''Lancelot'', ''Lancelot and Guinevere'' and ''Lancelot du Lac,'' making him the only character to have three episodes named after him.
* ''Series/ModernFamily'''s second-season ValentinesDayEpisode, "Bixby's Back", is a sequel to the first season's "My Funky Valentine", at least as it applies to Claire and Phil.
* ''Series/{{Psych}}'':
** The series has an episode called "Extradition: Canada" and another more recent one called "Extradition: Canada 2 (The Actual Extradition Part)".
** The {{season finale}}s of seasons 3-5: [[SerialKiller "An Evening With Mr. Yang"]], "Mr. Yin [[ThemeSerialKiller Presents ..."]], and "Yang 3 in 2D".
* The fifth-season ''Series/QuantumLeap'' episode "[[{{Recap/QuantumLeapS5E07DeliverUsFromEvil}} Deliver Us From Evil]]" is a sequel to the second-season episode "[[{{Recap/QuantumLeapS2E08Jimmy}} Jimmy]]": Sam leaps into Jimmy [=LaMotta=] a second time, a couple years after his first leap, and finds that the happy future he should have caused is failing to occur (thanks to an EvilCounterpart whose goal is to MakeWrongWhatOnceWentRight). This episode gets its own sequel later that season when the evil leaper returns in "[[{{Recap/QuantumLeapS5E16ReturnOfTheEvilLeaper}} Return of the Evil Leaper]]".
* ''Series/RedDwarf'' has the Series VI episode "[[Recap/{{Red Dwarf Season VI Emohawk Polymorph II}} Emohawk: Polymorph II]]", which is a sequel to the Series III episode "[[Recap/{{Red Dwarf Season III Polymorph}} Polymorph]]". The three-part special "[[Recap/{{Red Dwarf Back To Earth}} Back to Earth]]" also acts as a sequel to the Series V episode "[[Recap/{{Red Dwarf Season V Back To Reality}} Back To Reality]]".
* ''Series/{{Scrubs}}'': Some of the episodes are titled "His/Her/Their Story" (the usual episodes are titled as [[IdiosyncraticEpisodeNaming "My ___"]]) with [[NumberedSequels Roman Numerals used to indicate which part it is]]. These episodes focus on [[LowerDeckEpisode characters other]] than JD.
* ''Series/StargateSG1'' has what amounts to a ''{{prequel}}'' episode: "[[Recap/StargateSG1S4E162010 2010]]" is set entirely in a BadFuture, with the [[FutureLoser future versions]] of SG-1 working to send back a warning. The episode ends when they succeed, then a season later in "2001" the events referenced as history in 2010 start happening and they have to decypher the NoteToSelf to avert it.
* ''Franchise/StarTrek'' features several of these, spanning multiple series:
** The ''[[Series/StarTrekTheNextGeneration TNG]]'' episode "[[Recap/StarTrekTheNextGenerationS1E2TheNakedNow The Naked Now]]", for instance, was a sequel to the ''[[Series/StarTrekTheOriginalSeries TOS]]'' episode "[[{{Recap/StarTrekS1E4TheNakedTime}} The Naked Time]]".
** ''[[Series/StarTrekDeepSpaceNine DS9]]'' delighted in doing this to TOS, with "[[{{Recap/StarTrekDeepSpaceNineS05E06TrialsAndTribbleations}} Trials and Tribble-ations]]" as a sequel to the iconic "[[{{Recap/StarTrekS2E15TheTroubleWithTribbles}} The Trouble with Tribbles]]", and a whole series of sequels exploring the mirror universe introduced in TOS' "[[{{Recap/StarTrekS2E4MirrorMirror}} Mirror, Mirror]]".
** ''Film/StarTrekIITheWrathOfKhan'' could be seen as a feature-length sequel to "[[{{Recap/StarTrekS1E22SpaceSeed}} Space Seed]]".
** ''[[Series/StarTrekVoyager Voyager]]'': ''[[Recap/StarTrekVoyagerS5E17CourseOblivion Course: Oblivion]]'' is a sequel episode to ''[[Recap/StarTrekVoyagerS4E22Demon Demon]]''.
* ''Series/{{Supernatural}}'':
** The series has "Hell House" in season 1 and its sequel "Ghostfacers" in season 3.
** "{{LARP}} [[Film/LarsAndTheRealGirl and the Real Girl]]" and "Pac Man Fever", are sequels to "[[Literature/TheMillenniumTrilogy The Girl With The]] TableTopGame/DungeonsAndDragons [[Literature/TheMillenniumTrilogy Tattoo]], in which [[EnsembleDarkhorse Charlie]] first appeared.
* ''Franchise/UltraSeries'':
** ''Series/UltraQ'' did two episodes in which a MonsterOfTheWeek returns with a vengeance. They featured [[AnIcePerson Peguila]] and [[HumongousMecha Garamon]] respectively, with the latter's return episode revealing the alien invaders who had originally sent the first Garamon to attack Earth.
** The sixteenth episode of ''Series/{{Ultraman}}'' was one for its second episode, as the Baltans turn out to have survived Ultraman's destruction of their spaceship and they seek revenge.
** In ''Series/UltramanTiga'', the episode "Requiem to Darkness", in which Horii's friend Ryosuke transforms himself into the monster Evolu using alien cells, got a sequel towards the end of the show called "Goodbye to Darkness", where an escaped lab monkey mutated by the same cells into a new creature called Metamorga (naming pattern, anyone?) appears, while also grappling with some of the leftover issues from the previous episode, notably Ryunosuke's girlfriend Sayaka and her feelings for Horii.
** ''Series/UltramanDyna'' did a sequel to the above-mentioned Tiga episodes called "The Light and Shadow of Youth", which also served as a sequel to a ''Dyna'' episode called "Battle! Monster Island!" (which had a mad scientist and his mutant monster Neosaurus), as the mad scientist's apprentice perfects the alien cells to create super-soldier clones and eventually turn himself into the monster Zomborg. ''Dyna'' also did a sequel to the ''Tiga'' episode "The Phantom Dash" called " "The Phantom Dream Bird", in which a legendary bird-woman of ill omen named Kokakuchu warns Mayumi that "the tragedy will happen again", referencing her boyfriend's death at the hands of the monster Gazote in ''Tiga''. Kokakuchu soon appears at the power plant Gazote attacked, and the brother of Mayumi's late boyfriend is there as well...
** ''Series/UltramanMax'' did one to ''Series/UltraSeven'''s "The Targeted Town" called "The Untargeted Town", in which the alien Metron turns out to have survived his encounter with Seven and has restarted his HatePlague schemes with cellphone signals instead of cigarettes. The episodes even have the same director! There was also "A Different World", which serves as a sequel to the MultiPartEpisode that had Red King and Pygmon/[[SpellMyNameWithAnS Pigmon]] and the episode "A Bright World", as the alien Shama returns from the latter episode to destroy DASH and Ultraman Max with a device that summons a new Red King from a parallel universe where it was never destroyed, but accidentally brings in Pygmon too.
** ''Series/UltramanMebius''' "The Monster Master's Legacy" follows up an episode of ''Series/ReturnOfUltraman'' called "The Boy and the Monster Master" by featuring the son of the benevolent alien Mates (murdered in an incident of FantasticRacism) coming to Earth to avenge his father's death.
** ''Series/UltramanOrb'''s "The Girl with the Blue Ribbon" sees the SSP and Gai discover that their one-off alien foe Maddock from "A Heart That Won't Flee" has somehow reincarnated himself in the body of an amnesiac teenage girl and has also resurrected his monster Hyper Zetton Deathscythe.
* ''Series/TheWonderYears'': The fifth season premiered with "The Lake", where Kevin meets a girl named Cara while on vacation at the lake. The season ended with "Back to the Lake", where Kevin returns to the location specifically to reunite with Cara.
* ''Series/TheXFiles'':
** A first season episode "[[Recap/TheXFilesS01E21Tooms Tooms]]" was a sequel to an episode earlier in the season, "[[Recap/TheXFilesS01E03Squeeze Squeeze]]", one of the few they did like that. In the first ep they caught the MonsterOfTheWeek and in the later ep he was released from psychiatric ward. It's pretty damn hard to prosecute a supernatural crime...
** The episode "[[Recap/TheXFilesS02E13Irresistible Irresistible]]" had the sequel "[[Recap/TheXFilesS07E07Orison Orison]]". They featured a creepy serial killer obsessed with dead women and Agent Scully. In "Orison", he escapes from prison and tries to find Scully.
** "[[Recap/TheXFilesS03E17Pusher Pusher]]" had the sequel "[[Recap/TheXFilesS05E08Kitsunegari Kitsunegari]]". "Pusher" is considered a brilliant episode with a great antagonist for Mulder. "Kitsunegari" is disappointing as he inexplicably became helpful and his previously-not-mentioned twin sister has the same paranormal abilities (which he gained because of his untreated brain tumour).

* In ''WesternAnimation/{{Futurama}}'' the episode "[[{{Recap/FuturamaS2E19TheCryonicWoman}} The Cryonic Woman]]" is essentially a sequel to the pilot episode (showing how far Fry's come, reminding us of what his life was like before he was frozen and showing how someone might suffer for being a FishOutOfWater in his situation). They even pointed this out in the DVD commentary.
** During the episode "[[{{Recap/FuturamaS3E2ParasitesLost}} Parasites Lost]]", among the many changes to himself via a beneficial worm infestation in his body, Fry gains the ability to play a holophonor (it is said that not many people in the whole universe can play it, and the few that ''could'' can't play it well), cementing his relationship with Leela. However, to find out whether or not she loves the real him, Fry induces a PygmalionSnapBack by driving the worms out of his body. He tries playing the holophonor again, and as expected, he lost both his talent and his seduction over Leela. The episode ends with Fry practicing on the holophonor, but this is not revisited until "[[{{Recap/FuturamaS4E18TheDevilsHandsAreIdlePlaythings}} The Devil's Hands Are Idle Playthings]]", a SeriesFauxnale centering on Fry's ability to play the holophonor.

** "Be Mine" for both "Terra-ized" and "Opposites"; after a PreviouslyOn segment, it picks up where "Terra-ized" left off.
** In "[[Recap/TeenTitansGoS1E37Legs Legs]]", Raven loses her cloak, and she creates a new superhero identity called [[KickChick Lady Legasus]].

** "[[Recap/TheSimpsonsS2E15OhBrotherWhereArtThou Oh Brother, Where Art Thou?]]" shows Homer meeting his successful, [[LongLostRelative long-lost half-brother]] Herb, and ends with Homer ruining his brother's career and their relationship.

* ''WesternAnimation/StarTrekTheAnimatedSeries'' had several episodes that were sequels to episodes in ''Series/StarTrekTheOriginalSeries''.

* ''WesternAnimation/TeenageMutantNinjaTurtles1987'' had a couple. One was "Mr. Nice Guy," which was a sequel to the episode "Leonardo Lightens Up," as both plots involved one of the Turtles being affected by Donatello's personality ray. "Michelangelo meets Bugman," had a sequel that was naturally called, "Michelangelo Meets Bugman Again." "Adventures in Turtle Sitting" was a spiritual sequel to "Back to the Egg," as both had some of the Turtles reduced to five years old which left the one(s) who kept their natural age to look after them (notably, Leonardo was turned into a five-year-old in ''both''). "Menace, Maestro Please," was a sequel to "Name That Toon," and is notable for immediately following the previous episode unlike most cases.
* ''WesternAnimation/BatmanTheAnimatedSeries'' had "His Silicon Soul," which was a direct sequel to the 2-part "Heart of Steel", and "Day Of The Samurai" which was a sequel to the earlier "Night Of The Ninja." When the show became ''The New Batman Adventures'', "Joker's Millions" followed up on a plot point briefly mentioned in the "World's Finest" {{Crossover}} with ''WesternAnimation/SupermanTheAnimatedSeries''.
* ''WesternAnimation/TazMania'' had "Here, Kitty, Kitty, Kitty," and its follow up "Here, Kitty, Kitty, Kitty Part II," which saw an evil housecat owned by Taz's sister Molly try to kill Taz, and every single time Molly saw the two the cat would [[WoundedGazelleGambit pretend to be the victim]].
* ''WesternAnimation/RockyAndBullwinkle'' had the story arcs "Moosylvania" and the series finale "Moosylvania Saved."
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' episode "Skeletons in the Water Closet" ends with Billy's mom going crazy because of Grim. "Grim vs. Mom" has her coming back to settle the score. And then there's the Nigel Planter episodes, and the Secret Snake Club episodes.
* ''WesternAnimation/{{Arthur}}'': "The Blizzard" (Season 4) features the town pooling their food and coming together to deal with a power outage. A radio broadcaster makes wildly inaccurate forecasts. Much of this happens again during "The Blackout" (Season 12), with Dave Read remembering how bad the forecasts were.
** Likewise the two episodes that deal with D.W.'s Snowball.
* ''WesternAnimation/RenAndStimpyAdultPartyCartoon'' has "Fire Dogs 2" which is a sequel to "Fire Dogs", an episode of [[WesternAnimation/TheRenAndStimpyShow the original series]], though it has little to do with it apart from it starting where the original episode ended.
* In ''WesternAnimation/MickeyMouseClubhouse'', the episode "Goofy Babysitter" is a followup to "Goofy Baby", except instead of Goofy getting turned into a baby, Mickey and the rest of his friends end up transformed.
* ''WesternAnimation/MrBogus'' had "[[Recap/MrBogusS3E7SuperBogusFliesAgain Super Bogus Flies Again]]", as a follow-up episode to "[[Recap/MrBogusS2E8BogusToTheRescue Bogus To The Rescue]]".
* On ''WesternAnimation/HongKongPhooey'', there was always something connecting the two 11-minute segments.
* ''WesternAnimation/JusticeLeague'' had "The Return", a sequel to "Tabula Rasa" and "Ancient History", the sequel to "Shadow of the Hawk".
* ''WesternAnimation/TheTransformers'' was not as continuity-driven as later installments, but it did have a few episodes that connected to each other despite not being a multi-parter. For one impressive example, the "Five Faces of Darkness" five-parter comes directly after the [[WesternAnimation/TransformersTheMovie movie]]. "Thief in the Night" reveals what happened to Trypticon after fighting Metroplex in "Five Faces of Darkness". "Thief in the Night" is used to explain why Octane was banished by the Decepticons in "Starscream's Ghost". The ghost of Starscream would later reappear in both "Ghost in the Machine" and the ''WesternAnimation/BeastWars'' episode "Possession". Starscream's immortality would later be used to explain Rampage's in "Bad Spark".
* ''WesternAnimation/TheLooneyTunesShow'' has "Best Friends" and "Best Friends Redux".
* ''WesternAnimation/TheSmurfs'' had "Smurfette Unmade" as a sequel for "The Smurfette" and "Dreamy's Pen Pals" as a sequel for "The Astro Smurf".
* ''WesternAnimation/CodenameKidsNextDoor'': Had plenty over it's run they may have well been [[StoryArc Story Arcs]].
** ''Operation C.A.K.E.D'' (which were all named with a number at the end, save S.I.X) dealt with the K.N.D confronting the Delightful Children and trying to take their birthday cake away from them [[spoiler: Only failing in the the sixth one due to some clever manipulation by the [=DCfdtL=].]] Likewise the final episode, Operation I.N.T.E.R.V.I.E.W.S, was centered around this.
** "Operation C.A.B.L.E.-T.V." lead into "Operation E.N.D".
** "Operation: J.E.W.E.L.S.", "Operation: R.A.B.B.I.T.", "Operation: C.H.O.C.O.L.A.T.E.", and "Operation: L.I.C.O.R.I.C.E." and "Operation: C.A.R.A.M.E.L." detailed the story around Numbuh Five and her arch-rival, Heinrich
** "Operation: E.N.D", "Operation: T.R.A.I.N.I.N.G." and "Operation: G.R.A.D.U.A.T.E.S." which focused on Numbuh 2's brother, Tommy, training to be a K.N.D agent.
** "Operation: P.R.E.S.I.D.E.N.T.", and "Operation: S.N.O.W.I.N.G." set up "Operation: E.L.E.C.T.I.O.N.S." Detailing the fiasco with the school president and the consequences that followed.
* ''[[WesternAnimation/MyLittlePonyFriendshipIsMagic My Little Pony: Friendship is Magic]]'':
** [[Recap/MyLittlePonyFriendshipIsMagicS3E5MagicDuel "Magic Duel]] is a sequel episode to [[Recap/MyLittlePonyFriendshipIsMagicS1E6BoastBusters "Boast Busters"]].
** [[Recap/MyLittlePonyFriendshipIsMagicS5E8TheLostTreasureOfGriffonstone "The Lost Treasure of Griffonstone"]] is a sequel episode to [[Recap/MyLittlePonyFriendshipIsMagicS1E5GriffonTheBrushOff "Griffon the Brush Off"]], which aired five years prior.
** [[Recap/MyLittlePonyFriendshipIsMagicS5E12AmendingFences "Amending Fences"]] is a sequel episode to [[Recap/MyLittlePonyFriendshipIsMagicS1E1MareInTheMoon the first episode]] [[Recap/MyLittlePonyFriendshipIsMagicS1E2ElementsOfHarmony of the show]]. More specifically, ''the first three minutes of the first episode of the show''.
* ''WesternAnimation/WanderOverYonder'': "The Gift" for "The Gift 2: The Giftening"--despite the name, the ''first'' one is the POVSequel that continues slightly past where the first left off.
* ''WesternAnimation/StevenUniverse'' is normally a continuity-heavy series where things that change in one episode are regularly called back to in another, and some episodes' plots are directly derived from earlier ones:
** The episodes "Steven's Lion", "Lion 2: The Movie", and "Lion 3: Straight to Video" [[SubvertedTrope don't actually have much to do with each other]] as far as their individual plots are concerned, aside from Lion having a major role in each. "Lion 2" and "Lion 3" receive an ''actual'' follow-up in "Rose's Scabbard", which revisits certain elements of the previous episodes (in particular, Rose's armory and her CoolSword). "Lion 4: Alternate Ending" follows up on "Lion 3" in a different way, as Steven reassesses the message from his mother to find some hidden purpose.
** "House Guest", the first episode of the first season's second half, deals with one of the immediate consequences of "Mirror Gem"/"Ocean Gem", the half-season finale (Greg's broken leg, an injury he suffered in "Ocean Gem").
** "Open Book" is one to "Rose's Room". Both are set in the eponymous room, and both have a similar plot where Steven has to deal with the room's strange effects.
** "The Test" kicks off when Steven discovers that the Sea Spire mission from "Cheeseburger Backpack" was a test, which he thinks he failed.
** The first episode of season 2, "Full Disclosure", picks up directly from the ending of the season 1 finale, "The Return"/"Jail Break", as Steven tries to cope in the aftermath of the latter.
** "We Need to Talk" is a direct follow-up to "Story for Steven", both {{Whole Episode Flashback}}s centered on Greg and Rose. "Greg the Babysitter" is a third set later still, though the focus is a bit more on Greg specifically.
** "Coach Steven" centers on Garnet and Amethyst fusing, inspiring anxiety (and a song) from Pearl until their fusion goes out of control and Pearl has to stop her. "Cry for Help" starts with Garnet deciding to fuse with Pearl instead of Amethyst for a similar task, causing Amethyst to experience similar feeling (and also a song), [[spoiler:but their fusion goes wrong [[AddictiveMagic in a different way]]]].
** "Super Watermelon Island" is not only a sequel to "Watermelon Steven", it is also part of the resolution of two separate {{Story Arc}}s ([[spoiler:Malachite and the Cluster/Peridot's redemption]].)
** The plot of "Beach City Drift" is kicked off when Kevin, the guy who harassed Steven and Connie in "Alone Together", reappears, causing them to try to get back at him. In "Kevin Party", he comes back again and invites them to a party, which they use as an opportunity to reconnect when they'd spent the last few episode not speaking to each other.
** "Monster Buddies" ends with Steven hoping he'll find some way to help a gem monster he befriended. "Monster Reunion" begins with Steven discovering that his healing powers still work, and he partially succeeds in using them for just such a task.
** In "Historical Friction", the characters [[ShowWithinAShow put on a play]] about the founding of Beach City. "Buddy's Book" picks up where the play's story left off. However, it stars the play's {{Deuteragonist}}, which makes it more of a SpinOff Sequel Episode.
** "Tiger Millionaire" is a ProWrestlingEpisode where Steven discovers Amethyst wrestles as PercussiveTherapy, and joins her to have fun together. Several seasons later, "Tiger Philanthropist" shows they were still wrestling, but Amethyst quits suddenly because she feels better about herself, leaving Steven uncertain whether to keep at it or how.
** In "The New Lars", Steven possesses Lars' body. Everyone likes Lars more for this, and only Sadie gets suspicious, which makes Lars realize no one else really knows him. In "The Good Lars", Lars tries to use baking for a potluck as an opportunity to open up to other people.
* The ''WesternAnimation/MyLifeAsATeenageRobot'' episode "Raggedy Android" is about Dr. Wakeman making a suit that could disguise [[RidiculouslyHumanRobot Jenny]] as a human, but [[FlawedPrototype doing such a rushed job]] that people were far more scared of it than Jenny. "Return of Raggedy Android" centered on a newer version of the Exo-Suit that actually worked [[GoneHorriblyRight and far too well]]. The latter had a SequelHook for ''another'' possible SequelEpisode (the Exo-Suit was still alive and took Mr. Mesmer as a new host) [[WhatHappenedToTheMouse which was never resolved on-screen]] (though Mr. Mesmer was later shown to be fine, implying it was dealt with offscreen)[[note]]there actually was a plan for a third episode, in which the Exo-Suit kidnaps Brad and threatens to kill him if Jenny does not surrender herself to its control but Nickelodeon executives rejected it for being too disturbing[[/note]].
* ''WesternAnimation/AtomicPuppet'' does this a fair bit.
** "Atomic Detention" ends with Joey and AP accidentally driving Joey's [[ApatheticTeacher Apathetic]] SadistTeacher Ms. Erlenmeyer [[ItMakesSenseInContext into madness and supervillainy, and she ascends a portal into another dimension.]] It was seemingly forgotten for the next while, until "Erlenmeyer's Revenge", where Ms. Erlenmeyer returns to Joey's school, revealing that she has been transformed into the psychic Queen Mindbender by a malevolent alien entity from the dimension she entered.
** "Tick'D Off" picks up immediately after "Survival of the Feltest" with Joey, his dad, and AP coming back home from their camping trip, and Joey finding that a tick from the campsite has embedded into his neck and it becomes sentient when Joey and AP power up.
** "Monster Truck Invasion" sees the return of Zorp, the leader of the aliens from "Pizza Planet", in a new scheme ToServeMan. Then the episode ends with Zorp finding an astronaut chimp, which leads to the plot of "Buck Monkey".
** "Lacer Takes Over" is a sequel to "These Shoes", as it turns out the malicious A.I. of the [[TrickedOutShoes Lacer Hypertops]] has survived the destruction of its body to continue its scheme to lead machinekind in overthrowing humanity and find itself a new body.
* ''WesternAnimation/TheAmazingWorldOfGumball'' began doing sequel episodes during Season 3 as [[ContinuityCreep continuity began to play a larger part in the show]]:
** Both "The Burden" and "The Bros" act as sequel episodes to "The Shell", the latter moreso than the former. Each episode, all of which were aired on consecutive weeks, forms part of a loose trilogy about [[RelationshipUpgrade Gumball and Penny's relationship]] and [[FriendVersusLover Darwin's feelings towards it]].
** "The Nobody" deals with Darwin and Gumball finding out someone is living inside their house. [[spoiler:It turns out to be Rob, who they saw floating around in "The Void", but didn't help, and got out on his own.]] In turn, "The Nemesis" is a sequel to "The Nobody", about [[spoiler:Rob trying to take revenge for them abandoning him]].
** "The Man" is about Richard coping with his mother finding a new boyfriend and that his father abandoned him. "The Signature" follows this up as Richard attempts to prevent them getting married, [[spoiler:and ends up reuniting with his father]]. To a minor degree, "The Check" is a sequel to "The Signature", as the episode kicks off when Richard's new stepdad gives his grandkids a gift they start fighting over. "The Outside" follows up "The Signature", being about [[spoiler:the Wattersons spending time with Richard's father (and finding out why he left in the first place)]].
** "The Pest" deals with the (very minor) fallout from Anais rejecting Billy's friendship in "The Egg".
** "The Awkwardness" is a sequel to "The Hug", both of which are about the [[CringeComedy relentlessly awkward meetings]] between Gumball and someone he doesn't know. "The Cringe" follows this further, as the two attempt to discover ''why'' things between them are always so awkward.
** In "The Nest", the monster that's been kidnapping citizens of Elmore turns out to be [[spoiler: the Evil Turtle from "The Puppy".]]
* ''DangerMouse'': "The Hickory Dickory Dock Dilemma" had "The Clock Strikes Back" as its sequel.
* Occurs twice in ''WesternAnimation/DefendersOfTheEarth'':
** In "A House Divided", Ming turns the Phantom's estranged brother, Kurt (who believes he is the rightful Phantom) into N'Dama the Weather Demon and lures the Phantom and Jedda into a confrontation with him. Kurt/N'Dama reappears in "Family Reunion", where he is still out for revenge. His lust for power ultimately proves to be his undoing and he is KilledOffForReal.
** In "The Evil of Doctor Dark", Ming turns to the evil magician Doctor Damian Dark (a former Shadow Lord and an old enemy of Mandrake) to seek the three pieces of the Orb of Konos, which has the power to grant immortality. The episode's sequel, "The Return of Doctor Dark", sees the Defenders (along with their friend, Mara), Ming's forces and Dark racing to find the pieces of the Orb; in the end, Dark (like Kurt/N'Dama) is destroyed as a result of his own greed.
* ''WesternAnimation/BumpInTheNight'' featured some episodes that were continuations of older episodes.
** "It Sang from Beyond the Stars" and "Comfort Schmumfort" are both follow-ups to "Not of This Boy's Room", as they both featured the return of the alien duo Sleemoth and Gloog and alluded to Mr. Bumpy's first encounter with them.
** "Made in Japan II" serves as a sequel to the episode "Made in Japan" and focuses on the return of Little Robot.
* ''WesternAnimation/BuzzLightyearOfStarCommand'' had an episode called "Strange Invasion", which had Team Lightyear end up on Roswell, a planet inhabited by [[LittleGreenMen stereotypical green-skinned and large-headed aliens]] who mistook them for a threat. The episode had a sequel in "Stranger Invasion", where the heroes returned to Roswell and had to help the inhabitants fight back against the invading forces of Evil Emperor Zurg.
* The ''WesternAnimation/PoundPuppies1980s'' episode "Where Do Puppies Come From?", which had the Pound Puppies help out a dog named Rusty and his pregnant mate Lucy, was given a sequel episode in "Pups on the Loose", which had Rusty and Lucy entrust the Pound Puppies with looking after their new children.
* ''WesternAnimation/ChalkZone'' had a considerable number of episodes that served as continuations to previous episodes.
** "Follow the Bouncing Bag" is a sequel to "Hole in the Wall", where Vinnie Raton continues trying to carry out his scheme of discovering [=ChalkZone=] and exploiting the place and its inhabitants for profit.
** "Disarmed Rudy" is a continuation of "Pumpkin Love", as it has Jacko try to get even with Rudy for "stealing" his bride.
** There were a series of episodes devoted to Snap hosting a show where he has a Zoner sent out to shoot footage of [=ChalkZone=] wildlife or snoop on other Zoners. The individual episodes were "Beanie Boys to Men" (where Snap sent Spy Fly to observe the training of Skrawl's minions), "Wild [=ChalkZone=]" (where Snap tries to have Push obtain footage of blechy bugs), and "Journey to the Center of the Yeti" (where Snap tried to get Spy Fly to see if there were life forms lurking in the fur of the Yadda Yadda Yeti from "That Thing You Drew").
** "Killer Breath" and "Doofus Penny's Grand Opening" were both sequels to "The Doofi". The former had Doofus Penny try to help Doofus Rudy create the perfect art model by using an invention to merge baby's breath with the killer bush in hopes of creating a baby bush that will stay still, only to plague [=ChalkZone=] with a terror aptly named Killer Breath. The latter had Doofus Penny drag Snap into a tour of her Scientastical Hall of Wondoors.
** "Reggie the Red" had the episode's main conflict revolve around Reggie Bullnerd finding the piece of red chalk that nearly took over Rudy in "Battle of the Hands".
** "The Further Adventures of Super Hero Snap" serves as a sequel to "Super Hero Snap" and has Snap help Generic Man recapture the villain Major Brand after she escapes from the secure yet humane correctional facility Generic Man took her to.

* ''WesternAnimation/GravityFalls'': Season 1 had "The Time Traveler's Pig", in which Mabel and Dipper steal a time traveler's time machine so that they can win a pig and impress Wendy at the same time (each time they try, only one succeeds), inadvertently getting the time traveler, Blendin, fired for losing his time machine to a couple of kids. Season 2 has "Blendin's Game", where a disgraced Blendin challenges the twins to a game of Globnar to win his freedom and a "time wish" in revenge.

Two seasons later, "[[Recap/TeenTitansGoS3E2LegDay Leg Day]]" sees the return of Lady Legasus, who helps the other Titans appreciate their legs more and reinvents them as the League of Legs, with Robin as Captain Cankle, Cyborg as Thunder Thighs, Beast Boy as The Calf, and Starfire as the Incredible Quad. The League of Legs make another appearance later in the season with "[[Recap/TeenTitansGoS31ArmsRaceWithLegs Arms Race With Legs]]", in which Lady Legasus must save the day when [[WithGreatPowerComesGreatInsanity the rest of the league abuses their leg power]].

* Roger Stern's SpiderMan story, "Nothing Can Stop the Juggernaut" from the early 80s was followed up by 2009's "Something Can Stop the Juggernaut". And to make it even better, the sequel was written by Stern as well!

** In season 3 episode 2 "[[{{Recap/AngelS03E02ThatVisionThing}} That Vision Thing]]", a prisoner is freed from another dimension by Angel, who then returns 4 episodes later to cause havoc.
** Faith's return in season 4 may be considered this to her appearance in season 1, "[[{{Recap/AngelS01E18FiveByFive}} Five By Five]]" and "[[{{Recap/AngelS01E19Sanctuary}} Sanctuary]] ".

* ''[[WesternAnimation/RenAndStimpy Ren & Stimpy: Adult Party Cartoon]]'' has "Fire Dogs 2" which is a sequel to an episode of the original series, though it has little to do with it apart from it starting where the original episode ended.

** ''Series/UltramanDyna'' did a sequel to the above-mentioned Tiga episodes called "The Light and Shadow of Youth", which also served as a sequel to a ''Dyna'' episode called "Battle! Monster Island!" (which had a mad scientist and his mutant monster Neosaurus), as the mad scientist's apprentice perfects the alien cells to create super-soldier clones and eventually turn himself into the monster Zomborg.
*** ''Dyna'' also did a sequel to the ''Tiga'' episode "The Phantom Dash" called " "The Phantom Dream Bird", in which a legendary bird-woman of ill omen named Kokakuchu warns Mayumi that "the tragedy will happen again", referencing her boyfriend's death at the hands of the monster Gazote in ''Tiga''. Kokakuchu soon appears at the power plant Gazote attacked, and the brother of Mayumi's late boyfriend is there as well...
** ''Series/UltramanMax'' did one to ''Series/UltraSeven'''s "The Targeted Town" called "The Untargeted Town", in which the alien Metron turns out to have survived his encounter with Seven and has restarted his HatePlague schemes with cellphone signals instead of cigarettes. The episodes even have the same director!

* ''Series/{{Community}}'':
** "Advanced Dungeons and Dragons" from Season 2 had a follow-up "Advanced Advanced Dungeons and Dragons" in Season 5. Abed notes that sequel episodes often lead to the downfall of overly-proud creators, [[BaitAndSwitchComment which gives him the resolve to do it so he can prove his superiority to them]].

** The two part finale, "To Boldly Go", can be seen as this to "[[Recap/StarTrekS1E3WhereNoManHasGoneBefore Where No Man Has Gone Before]]", though more in the sense that it is meant to form BookEnds with that episode.

* ''WesternAnimation/TeenTitansGo'': "Be Mine" for both "Terra-ized" and "Opposites"; after a PreviouslyOn segment, it picks up where "Terra-ized" left off.

An episode in a series that serves as a sequel to a previous episode. Different from a TwoPartEpisode, in that there may be several episodes (if not several ''years'') inbetween the first episode and the one that picks up the plot again.

** There were a series of episodes devoted to Snap hosting a show where he has a Zoner sent out to shoot footage of [=ChalkZone=] wildlife or snoop on other Zoners.

** "Coach Steven" centers on Garnet and Amethyst fusing, inspiring anxiety (and a song) from Pearl until it their fusion goes out of control and Pearl has to stop her.

* ''TMNT1987'' had a couple. One was "Mr. Nice Guy," which was a sequel to the episode "Leonardo Lightens Up," as both plots involved one of the Turtles being affected by Donatello's personality ray. "Michelangelo meets Bugman," had a sequel that was naturally called, "Michelangelo Meets Bugman Again." "Adventures in Turtle Sitting" was a spiritual sequel to "Back to the Egg," as both had some of the Turtles reduced to five years old which left the one(s) who kept their natural age to look after them (notably, Leonardo was turned into a five-year-old in ''both''). "Menace, Maestro Please," was a sequel to "Name That Toon," and is notable for immediately following the previous episode unlike most cases.
