- Dr. Walter Bishop: [to Alistair Peck] I, too, attempted the unimaginable, and I succeeded. I crossed into another universe, and took a son that wasn't mine. And since then, not a day has passed without me feeling the burden of that act. I'm going to tell you something that I have never told another soul. Until I took my son from the other side, I had never believed in God. But it occurred to me... that my actions had betrayed him and that everything that had happened to me since was God punishing me. So now I'm looking for a sign of forgiveness. I've asked God for a sign of forgiveness. A specific one, a white tulip.
- Peter Bishop: I read that déjà vu is fate's way of telling you... that you're exactly where you're supposed to be. That's why you feel like you've been there before. You are right in line with your own destiny.
- Peter Bishop: Yeah, I read that deja vu is Fate's way of telling you that you're exactly where you're supposed to be. That's why you feel like you've been there before. You are right in line with your own destiny.
- Olivia Dunham: Well, do you believe that?
- Peter Bishop: Mm... no. It's a bit mystical for my taste. I never get them, myself. Maybe that's because I'm not on track with my own destiny.

- Dr. Walter Bishop: I'm telling you how to do this, but I am telling you... you cannot do it.
- Alistair Peck: Walter, God is science. God is polio and flu vaccines and MRI machines, and artificial hearts. If you are a man of science, then that's the only faith we need.
