Orphan Black, Season 1

Cosima:
Wow. Rich, man. This looks like a new blade inset in a much older handle. So the fish, is a bitch, semiotically speaking, with a universal wave acts symbol of fecundity. But these…

Felix:
Seriously, what is she on about?

Sarah:
Quiet, she's just weird.

Cosima:
Sorry, sorry, sorry. Okay going off on a tangent there. If she's not dead, we need to find her. Find out what she knows.

Felix:
Are you mad? She's a homicidal maniac.

Cosima:
Yeah, but we need to find out who she is Sarah. She's, she found us. She's got answers.

Sarah:
The only way I'm going to do that is going back to being a cop.

Felix:
No. No way. You're not going back to being Beth. Impersonating a dead officer - that's like a whole new crime.

Sarah:
I think I'm safest with the cops, to be honest with you.

Felix:
Did that actually just come out of your mouth?

Sarah:
Look, Art's already looking for the killer. I shadow him as Beth and let them figure out what's happened to her, and then, when I find that out, I can jump off and deal.

Felix:
Deal? I'm beginning to realize crazy is genetic.

Cosima:
Well, yeah, bad brain chemistry can be genetic, um, but environment, that's individual, right? I mean that's the whole nature/nurture question right there.

Felix:
Okay, let's talk nature. Out of nine so far, one's a psycho who killed four others, one committed suicide, one is a bloody soccer-mum, and then there's you. My crazy sister is sane by comparison.

Sarah:
Thanks Fee.

Cosima:
But… [holds up photograph of Helena's knife] I think this might help figure out where she's coming from, so - I'll look into it.
