It all makes sense now. I was supposed to die, in both universes. But when I didn't, I became a paradox and now, for the two worlds to heal, I had to be deleted. But, if I'm already dead in both universes, then why am I here? How am I back? Something's gone wrong Walter. I need your help.

Peter

I need you to figure out why no one remembers me. Why you don't remember me.

Peter

You asked for my theory! I never said it was flawless.

Walter

Olivia: Walter, he says you're the only one he will speak to.
Walter: Me?
Olivia: Walter, he says his name is Peter Bishop. He says he's your son.

Well, what choice do I have? I've been haunted for weeks with visions of a strange man. And now the man is here, in the flesh, in our midst, and no one will let me examine him or even see him. I'm kept in the dark knowing nothing. How's a man supposed to get some rest with all these uncertainties?

Walter

Peter: Olivia, thank God you're here.
Olivia: Who are you?

When I do that, people say I'm crazy. I suppose I've learned that crazy is a lot more complicated than people think.

Walter

I don't know, I just had a feeling; that he didn't want to hurt me, that he wanted my help.

Olivia

Walter, I don't think I'm going to get much sleep tonight either. What do you say to a root beer float?

Olivia

Ah, fresh air. I've forgotten how much I love it. I should have gotten out of the lab years ago.

Walter

If you don't mind, I think I should urinate before we leave. And don't worry, I packed us sandwiches!

Walter

Walter: Claire, will you please man the cameras in my absence.
Astrid: Really? Claire? That doesn't even start with an A.

You know they did a study on sarcastic people, and they get more illnesses than other people. Something to do with negative energy.

Robert Danzig

Fauxlivia: You know, being you and living your life, only me more homesick for my universe.It must be hard to develop trust in people when all you've got is yourself. It must be terribly lonely.

Fauxlivia: Yeah, keep telling yourself that.
