-->-- '''Terra'''

[[GrandFinale The last episode]] ([[WesternAnimation/TeenTitansTroubleInTokyo before the movie]]).

Also the one where Terra [[BackFromTheDead returns,]] [[HomeSweetHome albeit]] [[BroughtDownToNormal changed]] [[IJustWantToBeNormal forever.]]

Beast Boy encounters a girl who looks exactly like the long-presumed dead Terra, and there is a very real possibility that it is her. However, she claims to have no memories of being a Titan and lacks Terra's powers.
----
!!Tropes:
* ActuallyADoombot: [[spoiler:The Slade that Beast Boy fights and defeats ends up being a robot duplicate.]]
* AmbiguousSituation:
** It's not made clear if Terra legitimately has amnesia, is just [[FakingAmnesia faking it]] so she can live [[IJustWantToBeNormal a normal life]], or happens to be an IdenticalStranger to the ''real'' Terra.
*** However, plenty of lines all but confirm it is Terra and she's choosing to forget.
*** Should that be the case, it is unclear exactly how ''long'' she's been alive, as well as she was able to remove the neurosuit as it was completely fused to her nervous system.
** {{Discussed|Trope}} when the others are searching for the White Monster. Robin, Starfire, Raven, and Cyborg, while skeptical of Beast Boy's claims, openly ponder how Terra could've possibly returned (she either freed herself, the petrification effect simply just wore off, or an Earthquake could have occurred while they were gone).
*** Starfire wonders why, regardless of how, she never tried locating them. Raven points out that Terra wasn't exactly one of the good guys the last time they saw her, therefore, she probably didn't ''want'' to be found.
* AndTheAdventureContinues: "Beast Boy to Robin. I'm on my way."
* ApathyKilledTheCat: While the other Titans wonder how Terra could have recovered, Beast Boy doesn't question it, only caring that she's back.
* BackFromTheDead: As it's believed, Terra.
* BittersweetEnding: The episode ends with Beast Boy accepting that the Terra he knew is never coming back and joining his teammates in battle, showing that he's finally ready to move on, though he's not happy about it.
* BolivianArmyCliffhanger: Largely downplayed. Though it was never shown exactly how that battle ended, the episode ending with Beast Boy en route to help the Titans fight the creature, as well as Robin's earlier confidence that Beast Boy would be the one who'd be able to take the creature down, does give some assurance that they were going to win that fight.
* BolivianArmyEnding: The episode ends with Beast Boy finally joining in the battle against the new enemy. The resolution is not shown. (The [[WesternAnimation/TeenTitansTroubleInTokyo follow-up movie]] does not address this, although its very existence implies the creature was dealt with in some manner.)
* TheBusCameBack: This is the only episode of the season to feature Slade, and even that's just for one scene. [[spoiler:And he's later revealed to be a [[RobotMe robot clone]].]]
* CallBack: Slade sends one of his robotic duplicates to confront Beast Boy, just like how he did the same thing to Robin at the end of "[[Recap/TeenTitansS1E9Masks Masks]]".
* DenouementEpisode: With the season's main story arc having wrapped up with one episode to spare, the actual finale is more of a bittersweet coda.
* DidNotGetTheGirl: Beast Boy doesn't get Terra at the end.
* EndOfSeriesAwareness: Having the Titans return to Jump City to see that NothingIsTheSameAnymore, while Beast Boy has to learn to let go of the past, all points to telling the viewer to accept that the show is over and to watch something else.
* GrandFinale: Of the AndTheAdventureContinues variety.
* HardTruthAesop:
** The world is always changing and you need to stop living in the past and accept things as they happen, which Beast Boy learns.
** You also shouldn't push to restart a past relationship if the other person doesn't want to reconnect.
** [[CharacterDevelopment Learning to let go is a big part of growing up.]]
** NostalgiaAintLikeItUsedToBe, and what you consider to be happier times can be seen as just mostly as an awful, traumatic period for someone else.
* InnocentlyInsensitive: If the school girl really is Terra, then all of Beast Boy's attempts to restore her memory just remind her of all the horrible things she did and all the trauma she went through back in Season 2.
* MadeOfExplodium: The wooden support rafters explode when Beast Boy rams Slade into the abandoned park's rollercoaster.
* MaterialMimicry: The White Monster can copy substances that it touches. After becoming oil, it gains the ability to reform itself.
* NoEnding: Infamously so.
* NoNameGiven: The girl who is thought to be Terra never refers to herself by any other name.
* NostalgiaAintLikeItUsedToBe: All the schoolgirl can think about when Beast Boy reminisces over his time with Terra is that she sounded like a terrible person who betrayed him in the end.
* NothingIsTheSameAnymore: The Titans return after defeating the Brotherhood of Evil to find their home city changed.
* NotMeThisTime: Slade claims to have nothing to do with Terra's return, amnesia, or loss of powers.
* OffIntoTheDistanceEnding: The episode ends with Beast Boy running out of the school into a bright white light.
* PostFinalBoss: A variation. The monster that the Titans face is the last antagonist of the final season after the actual BigBad The Brain and his LegionOfDoom are defeated. However, the monster is different from the norm of your usual PostFinalBoss in that he's considerably more difficult to defeat and the episode ends on a cliffhanger with Beast Boy joining the fight against it with no actual resolution. Additionally, the Slade-bot is the last personal foe Beast Boy faces after his arc with The Brain.
* ShipSinking: Beast Boy given up on Terra eliminates any chance of the two ever becoming a couple.
* TitleDrop: "Things change, Beast Boy. The girl you want me to be is just a memory."
* ThatManIsDead: Assuming the schoolgirl really is Terra, given how she keeps telling Beast Boy to stop calling her as such, it's made very clear that she no longer wants anything to do with her old life.
* TwoLinesNoWaiting: While Beast Boy tries to get Terra to remember her past, the other Titans chase after a BlobMonster terrorizing Jump City.
* UnusuallyUninterestingSight: None of Terra's classmates seem to recognize her from her time as a temporary Teen Titan or the Slade-related terrorist who briefly took over the city at least a year ago.
** Also, none of her school's students or staff seem to notice or wonder why Beast Boy is at their school.
* TheUnreveal: Done on purpose. It's never actually revealed whether the girl Beast Boy meets in this episode is Terra with amnesia, or whether Beast Boy mistook the girl for someone else, etc.
* VillainHasAPoint: Slade says that if Terra doesn't remember her acts of heroism as a Titan, it's because she chooses not to. Beast Boy argues that she can't forget being a true hero and sacrificing herself to save everyone... ''but''... she didn't exactly have the best time when she had her powers. They were hard to control, which made her feel very insecure about herself. When Slade helped her control them, she owed him a favor by spying and betraying the Titans, something she felt ''very'' guilty doing. That's not even getting into the guilt she probably feels for nearly killing the Titans and taking over the city unopposed, as well as the trauma she endured from the Titans viciously fighting back and Slade beating her to a pulp when she retreated and technologically controlling her like a puppet. Even if this really is Terra brought back from the dead, she probably wants to avoid the chances of triggering another volcano. You can't really blame Terra for wanting to move past all of this, or Slade (though considering how he played a part in said trauma, he doesn't really have a leg to stand on) for outright calling Beast Boy out for telling her to remember something she doesn't want to. Perhaps Slade learned something from the battle with Trigon after the latter told him YouHaveOutLivedYourUsefulness.
* WhamLine: "Terra"'s first words to Beast Boy: "Sorry, you got the wrong girl."
* WhamShot: Terra's statue is no longer in the cave, making it clear that she's living flesh and blood.
* WhatTheHellHero: ''Slade'' of all people does this, calling out Beast Boy for continuing to force her to remember something she doesn't want to.
