Chuck: No. No, it's for Ellie.
Sarah: No, I'm sorry. There's no debate. It has to be you. You're the Intersect.
Chuck: I won't take it knowing that Ellie will die without it, that both of you have been poisoned, too.
Casey: You're a good person, Chuck, and I respect that, but I got a job to do. So take it before I shove it down your throat!
Chuck: Okay, okay. Fine, fine, I'll do it.
Sarah: Thank you.
Chuck: I'll pretend to agree to take it then run like hell to my sister's room and make her take it. Why did I just say that out loud?
Sarah: It's the poison, it makes you tell the truth.
Casey: You do that, I'll give chase, put a gun to your head, threaten to pull the trigger if you don't take it.
Chuck: Would you really shoot me?
Chuck: Yeah, don't waste a bullet. We're already dead. I'm saving my sister.
