"The more I hear about other worlds, the crazier it gets!" His whole world being turned upside down, and in a far different way than Sin ever did. "I never thought about different planets, other life--the idea never crossed my mind. There was just where I was. But now... now I'm here. It's like it shouldn't be real."

As reflective as it sounds, is, he says it lightly, not giving any credibility about how real or not there is. Though that does make the corner of his mouth twitch, and he shares wryly:

"There's a guy on the train who thinks we're part of his magic hallucination."
