Sarah and Felix in “Unfinished Business”

Something really weird just happened at the train station.

Felix

What?

I saw a girl kill herself.

Felix

Eeww. A jumper?

Yeah, and she looked exactly like me, Felix.

Felix

What you mean? [Sarah takes out Beth's wallet] Oh! You robbed her body.

No, she left a bag on the platform.

Felix

Isn't that essentially robbing her body? [Sarah shows him Beth's driver's license] Okay, that's …weird.

[sarcastically] Yeah, you think?

Felix

"Elizabeth Childs" — It's you with a nice haircut.

[looking at the address on Beth's license] That's a nice address. What the hell, Fee, did I have a twin sister?

Felix

Well, now, when you're a poor little orphan foster wretch, anything's possible. Or so we tell ourselves.
