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.
- And the Adventure Continues: "Beast Boy to Robin. I'm on my way."
- Apathy Killed the Cat: While the other Titans wonder how Terra could have recovered, Beast Boy doesn't question it, only caring that she's back.
- Actually a Doombot: The Slade that Beast Boy fights and defeats ends up being a robot duplicate.
- Ambiguous Situation: It's not made clear if Terra legitimately has amnesia, is just faking it so she can live a normal life, or happens to be an Identical Stranger to the real Terra.
- Bittersweet Ending/Downer Ending: A little of both. 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.
- Bolivian Army Ending: The episode ends with Beast Boy finally joining in the battle against the new enemy. The resolution is not shown. (The follow-up movie does not address this, although its very existence implies the creature was dealt with in some manner.)
- The Bus Came Back: Slade returns for the first time since Season 4's finale.
- Dénouement Episode: With the season's main story arc having wrapped up with one episode to spare, the actual finale is more of a bittersweet coda.
- Did Not Get the Girl: Beast Boy doesn't get Terra at the end.
- Grand Finale: Of the And the Adventure Continues variety.
- Made of Explodium: When Beast Boy rams Slade into the abandoned park's rollercoaster, the wooden support rafters explode.
- No Ending: Infamously so.
- Nothing Is the Same Anymore: The Titans return after defeating the Brotherhood of Evil to find their home city changed.
- Not Me This Time: Slade claims to have nothing to do with Terra's return, amnesia, or loss of powers. And he was right.
- Two Lines, No Waiting: While Beast Boy tries to get Terra to remember her past, the other Titans chase after a Blob Monster terrorizing Jump City.
- The Un-Reveal: 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. Although given that the "Schoolgirl" outright tells Beast Boy "things were never the way you remember" it should be incredibly obvious that it is in fact Terra who does remember and is choosing to repress her memories and powers.
- Villain Has a Point: 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 with betrayal of the Titans, something she felt guilty doing. And that's not even getting into the guilt she probably feels for nearly killing the Titans and taking over the city unopposed. And 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 blame Terra for wanting to move past all of this, or Slade 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.
- What the Hell, Hero?: Slade of all people does this, calling out Beast Boy for continuing to force her to remember something she doesn't want to.
