How we cite our quotes: (Chapter.Paragraph)
Quote #1
What if all the pieces of belief and memory that comprise who I am [...] are nothing but a tragic misfiring in that gray matter between my ears? (5.103)
Jason's first assumption when he wakes up is that some sort of crazy brain problem is causing his identity crisis. Maybe he is a famous scientist and only imagined that he had a wife and family. Amnesia is a thing, after all. Yikes. We have the heebie-jeebies just thinking about it.
Quote #2
Will I keep fighting to be the man I think I am? (5.103)
Jason considers accepting the identity that everyone keeps pushing on him, but he just can't do it. He can't shake the feeling that he belongs somewhere else. Of course, he's right, so it's a good thing he listens to his intuition in this case.
Quote #3
[E]ven though she isn't Daniela as I know her, I cannot hide from how madly I love this woman, even here and now, sitting in this bed, in this wrong world. (5.460)
It freaks Jason out to meet parallel-universe Daniela, not merely because she's a successful artist in this reality, but also because his feelings for her are as strong as ever. Does it count as cheating if it's with a version of your spouse from another universe? We're asking for a friend.
