Oh, she knows she's right. Alice knows that she's going to be right, later when this girl remembers. Not that she takes any satisfaction from that fact though - it'd be so much better and easier if she could snap the girl out of it right now, but it doesn't seem like there's anything capable of doing so.

So maybe she should leave this up to someone more capable. Or come back later, when this whole mess is over, to help and try to drag her back to the train.

But in the middle of this chaos, staying here doesn't seem like it's going to do much.

"Yes, I can see that. Then perhaps I shall leave you to be mad about it by yourself."

Not that she thinks the other will just let her leave, but.. you know, she's giving her a chance to do this the peaceful way! Don't say she never did!
