->'''Faith:''' I am not a killer! I am the Slayer! And you don't know the first thing about me.\\
'''Forrest:''' You really care what I think?\\
'''Faith:''' No. I don't care. God, I don't care.


Faith (in Buffy's body) stands by Joyce while Buffy (in Faith's body) is taken away in an ambulance. They discuss Faith and Joyce notes how horribly unhappy Faith must be. After their conversation, Joyce hugs Faith who is visibly uncomfortable by the sudden affection. Afterwards, Faith takes a bath. She tries to get used to her new body and practices saying phrases she thinks Buffy would say. Faith then crimps her hair, puts on sultry make up and wears leather clothes. Soon after, she buys a plane ticket with Joyce's credit card and goes out to meet the Scoobies.
Meanwhile, Willow and Tara talk about Faith and Tara confesses that she 'belongs' to Willow.

An armored truck runs into the police car holding Buffy and leather-clad operatives from the Watcher's Council jump out. They capture Buffy and put her in the back of their truck.
Faith attends a meeting at Giles' apartment alongside Willow, Xander and Anya (who makes Faith uneasy as she has no idea who she is). Faith happily tells the gang that Faith is on the way to prison but Giles tells them its unlikely as the Watcher's Council has sent a team to apprehend the rogue slayer and take her back to England. Faith is ecstatic at the news and goes out to celebrate at the Bronze until she runs into Spike. Once she realizes who Spike is, Faith begins teasing him and speaking to him seductively. When it's obvious Spike is confused but attracted to her, Faith tells him she wouldn't do anything to him anyway as it's wrong. Frustrated and furious, Spike promises that as soon as his chip is out, they'll have a confrontation. Faith merely smirks at Spike's threat and leaves.

Elsewhere a vampire pack led by Boone, return to their nest and find Adam waiting there for them. Adam talks to them and discusses their fears. He calls vampires a paradox as they are immortal but fear death more than mortals do.

Buffy finds herself chained to the back of the truck with the Council team. She tries to convince them that her body has been switched with the other Slayer but they're unfazed.
At the Bronze, Willow introduces Tara to Faith. While Willow gets some drinks, Faith doesn't try to maintain Buffy's personality and instead says some harsh, rude things to Tara. Willow returns and points out a vampire with a girl which Faith reluctantly goes out to slay. The girl thanks Faith for saving which surprises Faith.

One of the Council members enters the truck where Buffy is being held and she attacks him, threatening to kill him unless they let her go. The other two members tell her that they've settled their affairs and are prepared to die if it means accomplishing their mission. They tell her to do what she wants and unable to go through with her threat, Buffy lets the operative go.
At the Bronze, Tara notices the fragmented energy coming from Buffy and knows that 'Buffy' isn't who she says she is. She informs Willow and they prepare to perform a ritual to track Buffy's real energy.

Faith visits Riley and seduces him in the form of Buffy. At first, Faith is overtly sexy and provocative but Riley isn't interested in games and wants to make love rather than just have sex. After they sleep together, Riley tells Faith that he loves her which stirs Faith's real identity again. She attempts to leave quickly in the morning, leaving a sleeping Riley. She encounters Forest who confronts her about her influence over his friend and team mate. Meanwhile, Adam's eloquence has won over Boone's gang and they pledge their allegiance to him. He tells them they will announce his presence and decides to send them to what they fear most.

When the Council team realize they won't be able to get the Slayer to England, they decide they will kill her instead. Buffy however is prepared; she uses one of the operative's guns to break her chains and the lock on the door. She moves to the driver's seat and leaves with the armoured truck.

Faith is at the airport, preparing to leave town by obtaining a boarding pass for the plane. Buffy arrives at Giles' apartment and struggles to convince him of the truth about the body swap. She reminds him of his stint as a demon and his sexual encounter with her mother which sufficiently convinces him of her real identity. Willow and Tara arrive (with Tara being properly introduced to Buffy), having created a katra that will switch Buffy and Faith back the next time they make contact. After turning on the TV, they discover that Boone and his gang are holding hostages at a church. At the airport, Faith sees the same report on TV and decides to go back and face the vampires. Riley arrives wanting to help but Faith reminds him of his injury and asks him to stay outside. Buffy, Giles, Willow and Tara arrive with Giles acting hysterical to distract the police while Buffy slips inside.

Faith challenges the vampires inside, quickly taking them out before facing Boone. As he starts talking about how Adam has shown him the way forward, Buffy takes him from behind. The two Slayers fight with Faith punching Buffy several times whilst screaming emotional abuse (showing her punching what appears to be her own face while screaming these things shows the extent of Faith's self-loathing). Buffy grabs Faith's hand and the two swap back to their own bodies. The real Faith runs off and is gone without a trace.
The next day, Buffy and Riley are talking and Buffy realizes that Riley had sex with Faith whilst in Buffy's body. The revelation deeply troubles them both. Meanwhile, Faith leaves town on a cargo train.

!!Tropes in this episode include:
* ArentYouGoingToRavishMe: Faith tries to get Riley to do nasty things to Buffy's body, for some sick reason known only to her. The fact that he doesn't helps her along her HeelFaceTurn.
* AuraVision: Tara realizes something is wrong with Buffy because her aura is "fragmented," as if someone had forced something into it that didn't belong.
* BedTrick: It's a lot easier when you're wearing their girlfriend's body.
* BeingEvilSucks: Faith comes to realize this over the course of the episode. Doing evil in Buffy's body is unsatisfying, and when she does attempt to act like Buffy, GoodFeelsGood.
* BecomingTheMask: On the verge of leaving Sunnydale, Faith returns to deal with a gang of vampires who have taken over a church.
-->'''Faith:''' I'm Buffy. I have to do this.
* BirdsOfAFeather: Adam begins his recruiting of underworld denizens by comparing them to himself.
-->'''Adam:''' Vampires. Demons in a human body. You walk in both worlds and belong to neither. I can relate.
* BloodstainedGlassWindows: The Slayers and Adam's vampires brawl in a church full of parishioners taken hostage.
* BondageIsBad: The whole Riley/Faith sex scene and its aftermath seem to be arguing that BDSM and sexual role-play in general are a way for screwed-up people to evade true emotional intimacy.
* BondOneLiner: A vampire [[ScrewThisImOutOfHere tries to escape the church]] InTheHood only to run into Riley, who rips it off him and tosses the vampire into the sun, saying, "You forgot your coat" as he burns up.
* CallBack: Buffy saving Faith from a vampire; the reverse happened in [[Recap/BuffyTheVampireSlayerS3E15Consequences "Consequences"]], right down to her savior being suddenly revealed when the vampire dusts (as we see Creator/ElizaDushku on both occasions, the effect is particularly pronounced). Also from that episode, Buffy tries the HumanShield trick Faith used to escape from the Council.
* CarFu: The spec ops team kidnaps "Faith" by using a reinforced armored security truck to ram the police car.
* CatchPhrase: Faith thinks Buffy's is "[[AndThatWouldBeWrong Because it's wrong.]]"
* CharacterTics: Creator/SarahMichelleGellar and Creator/ElizaDushku do a good job of portraying each other's body language.
* ConcealmentEqualsCover: For once the "bulletproof car" cliche is justified, as Buffy makes her escape by stealing the armored truck.
* ContinuityNod:
** Buffy's anxiety when trying to start the truck fits in with the poor driving skills she showed in [[Recap/BuffyTheVampireSlayerS3E6BandCandy "Band Candy"]].
** Tara says that Buffy was cruel to her and may be possessed; Willow asks if hyenas are involved, referring to Season 1's [[Recap/BuffyTheVampireSlayerS1E6ThePack "The Pack"]], in which hyena spirits possessed Xander, making him act cruel towards Willow.
** A GettingCrapPastTheRadar version--Xander was a virgin when he had sex with Faith in [[Recap/BuffyTheVampireSlayerS3E13TheZeppo "The Zeppo"]], which is presumably why Faith wasn't [[SpeedSex impressed with his stamina]].
** Willow's grudge against Faith (and vice versa) harkens back to TheReasonYouSuckSpeech she gave to Faith in [[Recap/BuffyTheVampireSlayerS3E19Choices "Choices"]], as well as her anger over Faith sleeping with (and later trying to kill) Xander.
** Buffy urges the wetworks team to call Giles, and is curtly reminded that neither Giles nor Buffy Summers have anything to do with the Watcher's Council. Giles was fired in [[Recap/BuffyTheVampireSlayerS3E12Helpless "Helpless"]], and Buffy resigned in [[Recap/BuffyTheVampireSlayerS3E21GraduationDayPart1 "Graduation Day, Part 1"]].
* CrashIntoHello: Faith literally bumps into Spike while dancing at the Bronze. As per this trope, ShipTease ensues.
* DarkMessiah: Adam inspires a gang of vampires to [[FaceYourFears confront their fears]] by seeking victims in a church in daylight. Their leader is even willing to take on a Slayer.
* ADayInTheLimelight: To drive the point home, Creator/ElizaDushku is credited as "Buffy."
* DescriptionCut:
** Faith says she'll be "out there doing my job" (patrolling). Cut to Faith dancing wildly at the Bronze.
** At the end of the episode Riley says that Faith won't be back because she's "had her fun." Cut to Faith hiding in the back of a boxcar, an empty look on her face.
* DoesThisRemindYouOfAnything: Remember, that sweaty panting hand-holding eye-fucking falling-backwards-in-ecstasy scene between Willow and Tara is a ''spell''. A spell called "the passage to the [[DoubleEntendre nether-realm]]," which involves a [[TheImmodestOrgasm giant flaming "O" rising around them]].
* TheDoorSlamsYou: Buffy knocks out Weatherby with the vehicle door, when he comes running up with a pistol.
* DoubleStandardRapeSciFi: Averted--Buffy is furious that Riley slept with Faith, and it certainly fuels her desire for revenge [[Recap/AngelS01E19Sanctuary when pursuing Faith in Los Angeles]]. Might also double as a ContinuityNod if Angel ever mentioned Faith's earlier rape attempt.
* DramaticIrony: Faith's attempt to trick everyone into thinking she's Buffy actually works well on Buffy's loved ones, with not even Riley (Buffy's boyfriend) or Willow (Buffy's best friend) putting two and two together. The person who first realizes something is wrong is Tara, someone whom Buffy has never even met. Justified in that Tara is very in touch with magic and could tell from Buffy's aura that there was something fragmented about her.
* DramaticShattering: Furious over being [[TheTease sexually taunted]] by "Buffy," Spike throws his bottle against the wall and shoves aside an InnocentBystander, causing the chip in his head to jolt him with pain.
* EvenEvilHasStandards: At this point, Faith is truly evil. However, she finds that she cannot turn her back on those in need. Rescuing a girl from a vampire to maintain her cover as "Buffy" profoundly affects her, and when she hears about hostages in a church, rather than run off with Buffy's body, she chooses to save them--because she is [[BecomingTheMask starting to think of herself as Buffy in truth]].
* EvilLaugh: A [[LaughingMad disturbing one]] echoes over the end of the Faith-practicing-being-Buffy-montage. Faith also laughs when she's told that "Faith" is being taken to England by the Council and it'll be a long time before she'll be coming back--she has to stop when the Scoobies [[NotHerself give her a puzzled look]].
* EyesNeverLie: Buffy asks Giles why he can't just look into her eyes and instinctively realize it's her. When Willow says that Tara worked out what happened just by looking at her, Buffy casts a snippy look at Giles, who looks embarrassed.
* ExcessiveEvilEyeshadow: Another hint that "Buffy" is NotHerself.
* ExpositoryHairstyleChange: Faith gives herself the same curly hairstyle that Buffy did in [[Recap/BuffyTheVampireSlayerS4E9SomethingBlue "Something Blue"]] where she was also NotHerself.
* FadeToWhite: Willow reaching orgasm--that is, the nether-realm.
* FoeRomanceSubtext:
** Spike listens with a rapt expression as "Buffy" leans close and describes in lurid detail what she could do to him.
** Faith seems a bit taken with Riley after their lovemaking--giving him one last look [[BeautifulDreamer as he's sleeping]], [[SexyShirtSwitch pinching his shirt as a souvenir]], and stopping him from confronting the church vampires due to his injury. This is in pointed contrast to her dismissive attitude to other men she's slept with.
* {{Foreshadowing}}:
** Spike being mesmerized by "Buffy" taunting him foreshadows his obsession with Buffy in Season 5.
** The next stage in Adam's plan is shown by his gaining followers [[FantasticRacism across the vampire/demon divide]].
** Reading from a credit card, Faith reads the expiration date as May 2001. [[Recap/BuffyTheVampireSlayerS5E22TheGift "The Gift"]], [[spoiler:in which Buffy dies]], aired on May 23rd 2001.
* FriendVersusLover: Subverted; Willow thinks Tara is pulling this, but Tara means it [[NotHerself literally]].
-->'''Willow:''' I'm sorry you're feeling all blechy. But we'll get together with Buffy another time. Sometime soon. I think you'll really like her.
-->'''Tara:''' She's not your friend.
-->'''Willow:''' ...I may have overestimated the "you liking her" factor.
-->'''Tara:''' No, no. I mean, I don't--I don't think she's... ''her''.
* FunnyBackgroundEvent: Buffy tries to hold Smith hostage, but the two other spec ops guys just say they're all expendable and walk off. As they discuss what they're going to do with their prisoner if she continues to be troublesome, Smith goes flying out the back of the truck behind them.
* GettingCrapPastTheRadar:
** Faith taking a bath in Buffy's body. The shooting script makes it clear that she's touching herself "[[ADateWithRosiePalms intimately]]."
** Anya says that as the crisis is apparently over, she and Xander will have sex. Faith smirks. "Well, we certainly don't want to cut into that seven minutes."
** Faith's lurid description of what she can do with her [[SuperSexOrgans Slayer muscles]].
** Willow and Tara [[IsThatWhatTheyAreCallingItNow connecting to the nether realms]].
** A nervous Giles suggests to Buffy that, if she really is Buffy, he'll allow him to tie her up until he's confirmed her bona fides. Buffy retorts that they don't have time for bondage fun.
* TheGlomp: Buffy (in Faith's body) glomps Riley at the church, leaving him rather confused.
* GoodFeelsGood: Faith, forced to slay a vampire to maintain her cover as "Buffy," is profoundly affected by the victim's effusive thanks, and begins BecomingTheMask.
* GoodPeopleHaveGoodSex: Faith offers Riley the chance to indulge any dirty fantasy he wants. Instead Riley makes love to her so gently that Faith begins to freak out.
* GrandTheftMe: Buffy fears her greatest enemy will take her rightful body to Mexico.
* HeelRealization: Faith begins to come to terms with the fact that she has become a monster.
* HellBentForLeather: But not the Black Leather Pants of Evil, interestingly enough. Faith wears the Green Leather Pants of Jealousy, as seen on Willow in [[Recap/BuffyTheVampireSlayerS4E6WildAtHeart "Wild at Heart"]].
* HeyThatsMyLine
-->'''Anya:''' We were going to light a bunch of candles and have sex near them.\\
'''Faith-in-Buffy's-body:''' Well, we certainly don't want to cut into that [[SpeedSex seven minutes]].\\
'''Anya:''' Hey!\\
'''Xander:''' ''[to Anya]'' I believe that's my "hey." ''[to Faith]'' ''Hey!''
* HoldingHands: Faith deliberately takes Joyce's hand to taunt Buffy as she's being wheeled out on a gurney. Played straight with [[LesYay Willow and Tara at the Bronze]].
* ImmortalsFearDeath: Adam observes that vampires are more afraid of death than those to whom it comes naturally.
* ImprovisedWeapon: Faith breaks a pool cue in half to stake the Bronze vampire, and breaks off a piece of church pew later on.
* IndulgentFantasySegue: Faith-in-Buffy's-body imagines stabbing Willow to death, after Willow talks about how much she hates her. Faith is actually so shocked by the momentary lapse into fantasy violence that she backpeddles and tells Willow, [[PetTheDog "I would never let her hurt you."]] (It's worth noting that this is the only instance of such a sequence in the entire series, though a [[Recap/AngelS01E19Sanctuary similar sequence appears]] when Faith crosses over to ''Series/{{Angel}}'').
* IronicEcho: "I'm Buffy" and "Because it's wrong"--by the time Faith uses it at the church, she's [[BecomingTheMask bought into the Buffy role so much she actually means it]].
* ItDoesntMeanAnything: Faith tries to convince herself of this after having sex with Riley, babbling "[[TitleDrop Who are you?]] What do you want from her? This is meaningless."
-->'''Riley:''' You're shaking. What happened?
-->'''Faith:''' Nothing... Nothing.
* ItIsDehumanizing: When Buffy wakes up from the knockout drug, Weatherby sneers and says, "Well, it's awake."
* KeyUnderTheDoormat: Buffy's theft of the armored van is made significantly easier when she finds the keys hidden in the cab. [[IdiotBall Paramilitary spec-ops guys ought to know better.]]
* KickTheDog: Since Faith is trying to ruin Buffy's life, she does this with [[TrueCompanions Xander]] and [[TheWoobie Tara.]] She attempts this on Spike, but he's able to play it cool until she leaves.
* KilledMidSentence: Vampire Boone.
-->'''Boone:''' [[BadAssBoast I have strength you couldn't dream of.]] ''[punches Faith hard in the face]'' [[DarkMessiah Adam]] has shown me the way, ''[punches her again]'' and [[TemptingFate there is nothing]]-- ''[Buffy stakes him from behind]''
* LimitedSocialCircle: Willow is reluctant to invite Tara into the Scoobies because [[SecretRelationship she wants a friend that's hers alone]].
* LongingLook: Faith realizes instantly from the look Tara gives Willow that the two are attracted to each other.
* LoveConfession: Not as direct as three episodes from now, but close enough.
-->'''Tara''': I am, you know.
-->'''Willow''': What?
-->'''Tara''': Yours.
* MaleGaze: Used deliberately with a close-up of Faith-in-Buffy's-body bending over on Riley's bed. In her [[{{Fanservice}} tight leather pants]].
* MeaningfulEcho: Faith [[MirrorMonologue mocking Buffy in the mirror]], including several deliveries of "Because it's wrong!" She eventually says the line seriously when asked why she wants to stop the vampires at the church.
* MoralEventHorizon (InUniverse): Faith jumps it (again) with the GrandTheftMe plot and sleeping with Riley. Buffy is so angry, she shows up on ''Series/{{Angel}}'' determined to kill Faith regardless of who's in her way, even willing to go through her ex to get at Faith.
* MostDefinitelyNotAVillain: In an effort to avert this, Faith is shown in a {{montage}} practicing Buffy's speech patterns in front of the mirror, though a lot of it is how she views Buffy (a stuck-up tightass with no sense of fun) rather than how Buffy actually is (at that point in the series anyway).
* MrExposition: Unusually, not Giles this time.
-->'''Willow:''' You're Buffy. You and Faith switched bodies, probably through a Draconian Katra spell.
-->'''Giles:''' ''[to himself]'' She understands it better than I do.
* NeverHeardThatOneBefore:
** InvertedTrope--Giles is alarmed when "Faith" walks in the door.
--->'''Giles:''' Look, I-I know what you're going to say, and-and, uh--\\
'''Buffy-as-Faith:''' I'm Buffy.\\
'''Giles:''' ''[{{beat}}]'' All right, I didn't know what you were going to say.
** Collins also congratulates Buffy on having come up with one he's never heard before. Unlike Giles, he simply doesn't care, telling "Faith" she's just a package he's got to deliver. "I deliver the package. I don't much care what's inside."
* NotHerself: Faith keeps all her mannerisms, and has to wildly improvise when meeting Buffy's newer friends (like Anya) for the first time.
* NotRightInTheBed: Faith-as-Buffy aggressively flirts with Spike, and invites Riley to indulge in any kinky fantasy he wants.
-->'''Faith-as-Buffy:''' Oh, you wouldn't have liked Faith. She's not proper and joyless, like a girl should be. She has a tendency to give in to her animal instincts. ''[bites Riley's lip]''
* NotSoHarmlessVillain: The Watcher's Council goes from bumbling and inept to badass killers. This is justified by their agents being a special operations team, of a kind they haven't sent before. This is particularly apparent when Buffy tries the same hostage trick Faith used to escape the Watchers in [[Recap/BuffyTheVampireSlayerS3E15Consequences "Consequences"]]. They don't care.
* OffWithHisHead: Adam is showing Boone's vampire gang who's top dog.
-->'''Adam:''' You fear the cross. The sun. Fire. And, oh, yes... ''[pulls a vampire's head off through sheer strength]'' I believe decapitation is a problem as well.
* OutOfCharacterAlert: When Buffy-as-Faith tries to convince Giles who she is, she strokes her hand down the hair near her face, a Buffy CharacterTic.
* PoliceAreUseless: It's perhaps understandable that an ambulance with police escort does not stand up to a raid by a Council wetworks team in an armored van.
* PowerGlows: The katra Willow and Tara give to Buffy so she can switch back.
* PowerPerversionPotential: Faith's detailed description of how a Slayer's strength and endurance equals bedroom prowess. This wouldn't be the last time this comes up.
* PrisonRape: Faith-as-Buffy shocks Joyce by laughing over how "Faith" will be showered with affection by "big ole Bertha" in prison--she quickly backpedals, pretending to be upset over how Joyce was attacked. Ironically, Buffy has made similar comments in the past, though of course never in front of her mother.
* {{Professional Killer}}s: The Watcher's Council Special Operations Team.
* PunchClockVillain: While Weatherby [[KnightTemplar truly believes in the Council's mission]], Collins is just doing his job.
* PutOnABus: Faith doesn't reappear in Sunnydale until three years later. She does, however, become a recurring character on ''Series/{{Angel}}''.
* RageAgainstTheReflection: By the time [[GrandTheftMe Fuffy and Baith]] throw down, Faith wails on Buffy with [[PunctuatedPounding a number of derogatory remarks]]... about herself.
-->'''Buffy-in-Faith's-body:''' You can't win this.\\
'''Faith-in-Buffy's-body:''' Shut up! Do you think I'm afraid of you? ''[starts punching Buffy, beating her own face]'' You're nothing! Disgusting! Murderous bitch! You're nothing! [[YouMakeMeSick You're disgusting!]]
* RapeAsDrama: Faith's actions could be treated as rape, although legally it would be a murky issue even putting aside the supernatural elements. The consequences would be followed up on in the coming episodes and later in the season, and Buffy would even appear on Angel willing to go through her ex to get at Faith.
* ReadingYourRights
-->'''Weatherby:''' By order of the Watcher's Council, you are being taken into custody until such time--
-->'''Collins:''' Skip the speech.
* RealMenLoveJesus: Faith turns up at the church and finds Riley already taking charge of the crisis.
-->'''Faith:''' How'd you get here so fast?\\
'''Riley:''' I didn't, I'm just late for church.
* RelationshipReveal: Not that some fans still didn't get it.
-->'''Willow:''' I just want something that's, you know, mine.\\
'''Tara:''' [[PropertyOfLove I am, you know. Yours.]]
* RequiredSpinoffCrossover: Faith's story continues in the ''Series/{{Angel}}'' episode "[[Recap/AngelS01E18FiveByFive Five by Five]]".
* RevealingHug: Faith grimaces and pulls free of Joyce's embrace, not used to such [[AbusiveParents motherly affection]].
* RomanticTwoGirlFriendship: Tara needs something of Buffy's for the spell. Willow says the ring she's wearing belongs to Buffy.
* SeekingSanctuary: Inverted--on Adam's encouragement, vampires barge into a church and take everyone hostage to prove they've risen above old superstitions.
-->'''Boone:''' It's hard to believe. I've been avoiding this place for so many years, and it's nothing. It's nice, got the pretty windows, the pillars, [[BreadEggsMilkSquick lots of folks to eat]]. Where's the thing I was so afraid of? You know, the Lord? He's supposed to be here! He gave us this address. Well, we'll just have to start killing off His people, and see if He shows up.
* SelfHarm: Faith invites Riley to hurt her (in Buffy's body), then beats herself (Buffy in her body) in a rage.
* SexyDiscretionShot: The Riley/Faith love scene cuts away to Willow/Tara doing their spell with lots of [[SexMagic suggestive heavy breathing]], which means we have a SexyDiscretionShot covered by a GettingCrapPastTheRadar shot!
* SexyShirtSwitch: Faith dresses in Riley's shirt while NotStayingForBreakfast.
* ShootOutTheLock: Buffy's escape from the Council team begins when she gets a hold of one of their sidearms, and uses it to shoot her cuffs off, then break through the window into the armored van's cab.
* ShootTheHostage: Buffy grabs Smith when he tries to inject her and threatens to break his neck if the spec ops team doesn't let her go. They tell her to go ahead, as they get their affairs in order before every mission.
* ShoutOut: Willow says Faith switched bodies through a Draconian [[Film/StarTrekIIITheSearchForSpock Katra]] Spell.
* ShowingOffTheNewBody: Faith's first impulse is to [[BathtubScene take a bath]], [[BathKick show off her legs for the camera]], and grope her new body extensively.
* SpeechImpediment: Tara starts stuttering when Faith talks about how much Willow loved Oz; Faith then mocks her for it. This [[KickTheDog casual cruelty]] tips off Tara [[NotHerself that Buffy isn't the friend that Willow has described to her]].
* SpitefulSpit: Weatherby spits in "Faith's" face.
-->'''Weatherby:''' The Watcher's Council used to mean something. You perverted it. You trash. We should have killed you while you were asleep.
* SpotTheImposter: Buffy is quite able to convince Giles that it's her, by rattling off a string of rather embarrassing facts about their relationship that Faith couldn't know.
-->'''Buffy-in-Faith:''' Giles, [[Recap/BuffyTheVampireSlayerS4E12ANewMan you turned into a demon]] and I knew it was you! I mean, can't you just look in my eyes and be all intuitive?
-->'''Giles:''' ''[suddenly interested]'' How did I turn into a demon?
-->'''Buffy-in-Faith:''' Oh! 'Cause, uh... Ethan Rayne! And-and you have a girlfriend named Olivia, and you haven't had a job since we blew up the school ''[{{beat}}]'' [[DamnWithFaintPraise which is valid, lifestyle-wise]]. ''[Giles is abashed]'' I mean, it's not like you're a slacker type or-- Oh, oh! [[Recap/BuffyTheVampireSlayerS3E18Earshot When I had psychic power]], I heard my mom think that you were [[Recap/BuffyTheVampireSlayerS3E6BandCandy like a stevedore during sex]]. Wh-- Do you want me to continue?
-->'''Giles:''' Actually, I beg you to stop.
-->'''Buffy-in-Faith:''' What's a stevedore? [[note]]A type of dock worker who unloads boat merchandise. Needless to say he has to be very fit regarding, ummm... repetitive tasks.[[/note]]
* StunnedSilence: After Buffy performs the body switch to return her and Faith to normal, she just sits there in a momentary daze. The look on Faith's face, meanwhile, [[VillainousBreakdown indicates the horror she feels]] from her HeelRealization.
* TheTease: Faith taunting Spike at the Bronze reaches fetish levels. It's not surprising he still remembers it in Season 7's [[Recap/BuffyTheVampireSlayerS7E18DirtyGirls "Dirty Girls"]].
-->'''Faith-as-Buffy:''' I could have anything. Anyone. [[DatingCatwoman Even you, Spike.]] I could ride you at a gallop until your legs buckled and your eyes rolled up. I've got muscles you've never even ''dreamed'' of. I could ''squeeze'' you until you pop like warm champagne and you'd ''beg'' me to hurt you just a little bit more.
* TemptingFate / WhereIsYourXNow: The vampires say they're going to start killing people in God's house and see who turns up to stop them. [[AntiHero Faith does.]]
* ThatCameOutWrong: Riley has just found out the woman he slept with was Faith.
-->'''Riley:''' Man, would I like to get my hands on her. ''[quickly]'' Not in a sex way.
* TitleDrop: "Who are you?" is [[RuleOfThree said three times]]: Buffy to Weatherby, Faith to Riley, and Riley to Buffy.
* TokenGoodTeammate: Smith seems to be this, being the only one to question the need for Faith's execution.
* ToMakeALongStoryShort: Willow already knows what happened to Buffy thanks to the nether-realm spell, saving Buffy the need to explain to Giles.
* TransparentCloset: Faith figures out Willow and Tara's mutual attraction in about eight seconds.
-->'''Faith:''' So, Willow's not driving stick anymore.
* TravelingAtTheSpeedOfPlot: Buffy, on her way to Giles after her escape.
* TwoPartEpisode: Faith stole Buffy's body in the last seconds of [[Recap/BuffyTheVampireSlayerS4E15ThisYearsGirl "This Year's Girl"]]; now, we find out what she does with it.
* UnusualEuphemism
-->'''Willow:''' What's wetworks?\\
'''Xander:''' [[BlatantLies Scuba-type stuff.]]\\
'''Anya:''' [[BrutalHonesty I thought it was murder?]]\\
'''Xander:''' Well, yeah. ''[lamely]'' But there could be underwater murder, with snorkels.
* VerbalBackspace:
** Faith-as-Buffy says that Buffy-as-Faith being arrested is poetic justice. When Anya asks what that means, she has to backpedal and say it's actually just regular justice.
** Willow: "I wish those Council guys would let me have an hour alone in the room with her... if I was larger and had grenades."
* VictoriasSecretCompartment: Faith steals money from Joyce's purse and tucks it inside her blouse.
* VillainEpisode: For Faith.
* WeNeedADistraction: Giles pretends to be a distraught family member to allow Buffy a chance to slip past the police line into the church. Unfortunately his acting [[BadBadActing needs some work]].
-->'''Giles:''' Damn it, man! We have to get inside! Our, uh, uh, families are-are in there! Our, uh, m-mothers and-and tiny, tiny babies!
* WhatYouAreInTheDark: Faith is on the verge of leaving Sunnydale when she [[CoincidentalBroadcast happens to see the news]]. She returns to save the people in the church.
* WhileYouWereInDiapers: Faith to Forrest.
-->'''Faith:''' I've been fighting demons since before you could shave.
* WhoAreYou: The TitleDrop--Faith asks it of Riley (after being freaked out by his gentleness) and later Riley asks the question of Buffy (being puzzled as to why a strange girl is addressing him in a familiar manner).
* WithMyHandsTied: Collins goes to execute Buffy-in-Faith's body; Buffy grabs his pistol between her feet and pulls his head into the bars, then uses the gun to [[ShootOutTheLock shoot out the various locks]].
* YouJustToldMe: Subverted; Buffy is apprehended by the police and Faith-in-Buffy's-body remains alone with Joyce. The first thing Joyce says is "Faith," and the changeling indeed reacts involuntarily, so it does looks like Joyce deduced her true identity. However, it turns out she didn't and is just wanting to ask "Buffy" about Faith.
* YouMustBeCold: Joyce wraps her coat around Faith, which she doesn't really notice, as she's too busy smirking over Buffy being hauled away by the police. She does notice when Riley wraps a blanket around her later because she's shivering.
