Am I missing something here? This is the same girl who betrayed us, correct? Same dick?
I like her.
~ Brenda and Gally.

Well, I don't know. We don't necessarily need her, right? Not all of her. We just need her finger.
Gally, back off.
What are you, squeamish? I guarantee you she's done a lot worse to Minho.
That's not the plan, back off.
~ Gally and Thomas talking about Teresa.

Why are you helping us, Gally? I put a spear through your chest.
Yeah, nobody's perfect, man.
