Did Charlie really mean it or did he have second thoughts?
In Corey's Been Dead for an Hour (S4 E9), Charlie finds Alan's stash of money and will only return it if Alan agrees to spend it all.
Alan says he has financial anxiety and he keeps that money as a back up so he doesn't end up homeless. Charlie then insinuates that he should spend that money regardless since Alan will always be able to live with him till he's gone.
Alan tries to reaffirm this and question Charlie's sincerity, "Really, you mean, no matter what? I can always count on you?"
Charlie ponders for half a second and then tosses the money back at Alan saying "keep the money".
Deep down, did Charlie really mean it but decided to avoid answering because he didn't want to be vulnerable, or did he have second thoughts and change his mind?
