Casey: [to Chuck] I made my decision between love and love of country a long time ago, and it was the right decision for me. You have to make a decision whether it's the right one for you. Walker's a good woman. It's still not too late.

Casey: [to Chuck] If my primary objective wasn't to protect you, I'd kill you.

Casey: [to Lester and Jeff] We could do this the easy way or the hard way. The easy way is I shove his foot up your ass.
Jeff: What's the hard way?
Casey: I use my foot!

Casey: [to Morgan about Alex] You break her heart, I break your everything.

Casey: [to Morgan] And a moron again! Sorry moron still.

Casey: Bang up job, Walker. Now I'm gonna give you one last chance to come clean. Did you or did you not compromise yourself and the Intersect?
Sarah: Do you ever just want to have a normal life? Have a family? Children?
Casey: The choice we made to protect something bigger than ourselves is the right choice. Hard as that is for you to remember sometimes.

Casey: Because the thing I hate more than hippie, neo-liberal fascist anarchists are the hypocrite fat-cat suits they eventually grow up to become.

Casey: Beckman was out of line pulling me off this mission.
Sarah: I agree with her. You're too emotionally involved.
Casey: This from the agent that can't keep her chocolate out of Bartowski's peanut butter.
Sarah: Whatever my feelings may be for Chuck I never knowingly endangered the asset. You let your anger towards Bennett cloud your judgment.
Casey: Finally you admit that you do have feelings for the nerd.
Sarah: No, all I will admit to is having feelings.

Casey: But haven't you personally given me the order to kill that commie crackpot on three separate occasions?
General Beckman: And three times, you have failed to complete your orders.
Sarah: Thought you said you had a perfect record.
Chuck: Wow. This is getting entertainingly uncomfortable.

Casey: Chuck! Sarah!
Sarah: Casey, What are you doing here?
Casey: Someone needs to protect the Intersect.
Chuck: Very thoughtful. Thank you very much, I guess.
Casey: Plus, I didn't want to miss any gun play. Come on.

Casey: Chuck, how'd you get here?
Chuck: My mom dropped me off.

Casey: Chuck, stop freaking out.
Chuck: Oh I'm not freaking out. And I'll tell you why I'm not freaking out, because that would require me overreacting and I don't think it's technically possible to overreact to my brother-in-law being kidnapped!

Casey: Credit card charges show mostly video games, comic books. Phone records indicate only one female caller in the last six months: his sister.
Chuck: I feel so sorry for this guy, he seems so alone.
Casey: Oh, whoops. That's your old file, Bartowski.

Casey: Decided to take up bird watching?
Chuck: Just breathing in the view.
Casey: Hmm.
Chuck: I know that grunt. Yeah, that's the number 7, right? Skeptical with a side of cynicism.
Casey: Just clearing my throat. Just couldn't help but notice Agent Walker's car isn't in her usual spot.
Chuck: Oh, I didn't, uh...It's weird. I didn't notice, I didn't see that at all. Fine maybe I did. So? Have you talked to Sarah lately?
Casey: Agent Walker and I don't do a lot of fraternizing off hours. Guess we'll just have to see.
Chuck: See...See What? Why? See what?
Casey: See if she's had enough of the good life with you. See if she's hightailed it to wherever your buddy Bryce is hiding himself.
Chuck: Is that, uh, is that an option?
Casey: Oh, Don't worry. I hear there's a great selection of new handlers in this year's CIA Christmas catalog.
Chuck: Are there? Thanks a lot.

Casey: Does the word "silent" have a different meaning in geek that I'm not aware of?
