Walter: Two thoughts to come to mind. The first, that this affliction might have been caused by a mutation, changing these lipids to seal any and all orifices. Did they check his anus and penis?
Peter: You think we could get the answer to that question without me in the room.

How come when nobody knows and it doesn't make sense, they come to us?

Olivia: Is your father about?
Peter: Right here. Why don't you ask him what he's doing?
Olivia: I'd rather not.

Olivia: Prep Hicks. Ready or not, we're administering the antidote.
Walter: An experiment. How exhilarating.

Olivia: Cut open his hand.
Peter: What?
Olivia: I want to see if there's a disk in it like Bowman's.
Walter: I like cutting.

Astrid: It also gave him four extra nipples.
Peter: Maybe he mutated into an opossum.
Walter: No, opossum's have 15 mammaries, unlike most mammals, who have an even number of nipples. Hence, the one half rule regarding nipples.
Astrid: The one half nipple rule?
Peter: You just had to ask, didn't you?
Walter: The typical number of young in the litter is usually equal to half the number nipples on the animal. The number of nipples being the maximum litter size. Humans, for example, one child is the typical. Maximum, twins. Barring extraordinary cases when the young exceed the number of nipples.
Peter: God, I hope I never have to hear him say the word "nipple" again.

Bowman: What weapons do you have? What weapons?!?
Male Flight Attendant: We have a taser in the cockpit which I will use on you if you don't calm down.
Bowman: Taser won't do a thing. It'll just piss me off.

Walter: With all due respect, Darwin got it all wrong. I used to make the joke that Darwin's thinking was rather... unevolved.
Peter: Which I'm sure used to be very funny.

Peter: I think I got a guy who can help us.
Olivia: Who?
Peter: Do you really want to know?
Olivia: Good point.

With all due respect, Agent Harris, I have done my due dilligence. I just got off the phone with my contact at the CDC. And they have seen nothing like it. But you tell me, does this look like a flu you've heard of? Where people's brains come out of their ears?

Olivia

Peter: I don't underestimate my father, by the way. I understand him. Sometimes more than I want to. Look, if I let him talk to that woman, she's just going to accuse him of killing her daughter, which is something he didn't do.
Olivia: Then why not just let them meet?
Peter: Whose side are you on anyway?
Olivia: I know what it's like to live with something unresolved. That's all.
Peter: Congratulations. You just described the entire planet.

Walter: It's a shame I don't have a lab. I'd like to examine him.
Peter: You do have a lab, Walter. Your lab at Harvard.
Walter: Yes. I do, don't I?

Just your average multi-national corporation specializing in secret bio research and defense contracting. Massive Dynamic. Seems like such an innocent name for a corporation, don't you think?
