tell me who randomly starts to sing when he's feeling unconfortable about something, it's weird, who does that?
In fact, NOTE: you don't need to edit your post, but him mentioning appalooza seemed forced to me, because no one was talking about the direction of the train, and he randomly bringed the subject up. He asked the location of Appalooza like he didn't know, but even if he didn't know he started to freak out for no reason.
Read Amber's posts, she seemed more natural when she started to react when she found out that she was heading to Manehattan.
