- [after Olivia realizes Peter is not from this Universe]
- Dr. Walter Bishop: Olivia. Please don't tell him.
- Dr. Walter Bishop: Perception is largely an emotional response. How we feel affects the way we see the world.
- Agent Olivia Dunham: I have a freakishly good memory. I remember everything.
- [about the lab in Jacksonville]
- Agent Olivia Dunham: Not this. There's just nothing that's familiar.
- Dr. Walter Bishop: My theory was wrong. This wasn't a quantum event at all. We're standing in two buildings... one of which comes from the alternate universe.
- Dr. Walter Bishop: The universe seeks balance. We sent a car over there so a car of equal mass came back. Now, a building from the other side appeared here. The laws of physics demand both sides of the equation balance. I calculate that a building from this side will be pulled over there... inhabitants and all... within the next... just under 35 hours.
- Astrid Farnsworth: All right, so what am I looking for?
- Dr. Walter Bishop: Anything that looks like it doesn't belong.
- Astrid Farnsworth: I think this qualifies. Richard Nixon on a silver dollar.
- Dr. Walter Bishop: That's disturbing.
- Agent Olivia Dunham: So what are the odds of something like this occurring naturally?
- Dr. Walter Bishop: Oh, it's possible. But if so, God has a far more disturbed sense of humor than even I could have imagined.
- Dr. Walter Bishop: I know what Newton did... .and I'm afraid I've just remembered what's going to happen next.
