I've seen people talking about what the twist in the The Lich will be. I didn't find any blogs about it, so I decided to make one. Leave comments about your theories, and I will add them to this post!
Oh, and by the way, not all of these are mine. Only the Finn's arm one and the explosion are my ideas.
- Marceline's Betrayal.
- Finn loses his arm, and gets a robotic one.
- (Personally, I doubt this) FP or PB's death.
- Lich-Possessed Rainicorn pup(s)
- Jake's death
- Peppermint Butler(or Gunther) is revealed to the puppetmaster behind the Lich.
- Ice King dies
- A new human character
- (This doesn't even make sense, as there is a sixth season)Everybody dies.
- The Lich is Finn's father (LOL)
- The destruction of Finn's hats.
- Death of Billy or Beemo.
- The episode ends with an explosion that could have killed a main character, and we don't find out if they are alive until the first episode of Season 5.
EDIT: Turns out that the Finn's arm and Death of Billy ones were technically true, we'll have to wait until Season 5 to find out!
Comment with more theories and discuss the currently posted ones.
