so before The Vault aires i just want some guesses on who this Green Ghost lady is. I know some people think its Finn's mom or relitive but who else could it be? When people say theat the Ghost Lady is his mom your also saying that Finn's bigest fear is his mom, and in SOME situations it could make sense that he is scared of his mom.
In the preview Finn puts the Ghost lady in the Vault and he says " Thats where the stuff I can't handle goes" so even if he is scared of his mom He wouldn't remember why he was scared or why he can't handle it. So, in other words I, personaly, Don't think the Green Ghost Lady is Finn's mother But, hey i might be wrong. Who else could this Ghost lady be? Or who do you think she is ( If you do think that she is finn's mom please comment why)
