[@Holy Soldier] I can come up with a post ASAP.

I just have a question to double check with you before I do: After CHECKing, Frisk knows that Wario is immortal but doesn't know whether that soul is truly Wario's soul or not. Do I have that right?

I figure after seeing the little Wario's behavior they can figure out that Wario is a greedy cheater at heart.
