I think he'll turn into a vampire.
(Bea comes into the Kennedy house. Finn is sitting on the couch.)
Bea: Hey Finn, I've just been interfering in my ex-boyfriend's life again even though he's perfectly capable of looking after himself.
Finn: That's nice.
Bea: What's the matter, Finn? You sound different.
Finn: You know how before the amnesia i was evil?
Bea: Yes?
Finn: Well now i'm even more eviller!
(Finn then turns around and opens his mouth. Revealing two fangs.)
Bea: Whoa, hold on. You're a vampire now? Crazy stuff. Now hold on whilst a sing a song to process my feelings.
