Kate Leavitt: I don't care if Bradberton made you the Pope. You're not telling me what to do anymore! We've been stuck down here for weeks. There is no Bradberton anymore. There's no Nuka-World anymore. No NOTHING anymore! Don't you get it, Rex? We're done. Humanity's done. We might be all that's left... and you want to continue working on this bullshit project?!
Meacham: Why don't you wake up, Kate? You don't know what's going on out there. There could be Chinese soldiers right above us, and we'd never know. Project Cobalt could be the thing that saves us... saves America. We have to keep working!
Bennell: I wish the two of you would stop fighting. We need to keep level heads if we're going to survive. Look, Kate... maybe Rex is right. Maybe if we concentrate on our work, it'll take our mind off of things for a while. None of us want to end up like... like Dr. Medford.
Meacham: Look, I don't deny it's a shame what happened to Dr. Medford, but at least he kept his mind on his work. The fact of the matter is, he lost it... he was weak. He let his emotions take over. I don't want to see the same thing happen to you.
Kate Leavitt: You're crazy. At first, I thought you were just driven... but I was wrong... you're absolutely crazy. Why don't you pull out some of your "secret" recordings you've been making of us... you know, the ones you think we don't know about. Play them back and listen to yourself over the last few weeks... listen to how goddamn insane you sound. Well you know what? I'm done. I'm done with you and I'm done hiding down here waiting until you snap.
Meacham: Get away from the door controls, Kate. I'm not kidding.
Kate Leavitt: A gun? So what are you going to do? You going to shoot me now? Is that what this has come to?! I said this to you a few months ago, and I'll say it again. Go to hell, Rex... and goodbye.
Bennell: Oh my god. You... you shot her. She's... she's gone.
Meacham: I had to do it, Kevin. She left me no choice. Now let's take care of this mess and get back to work.
