Castle Season 4 Episode 9

Burke: The psychological trauma is every bit as real as the physical trauma.
Beckett: Listen, people are dying out there. I don't have time to get all weepy over a couple of scars.
Burke: Okay. So what's the alternative, walking around feeling like you have crosshairs on your back, thinking every glint off a window is a sniper's scope?
Beckett: Look, there's gotta be a pill out there or something, right? Something to take the edge off.
Burke: Medication can help... but not right away.
Beckett: Well, then what?
Burke: Well, for one, I think you should consider stepping away from the case.
Beckett: You don't think I can handle this?
Burke: I'm saying...you don't have to. You're not the only cop in the city, Kate.
