Meredith (to Burke and Dylan who are whispering to each other): Stop it. I'm not a patient.
Meredith: The two of you are looking at me the way we look at patients. Like I'm going to freak out at any minute. I'm not gonna freak out so whatever it is just tell me straight out.
Burke: The main oxygen line runs directly under this room.
Meredith: Okay. (Burke just stares at her) Not okay... Well? I need one of you to tell me what this means, exactly. Because I think I know what it means, but I tend to be glass half empty these days. So, I won't trust what I think it means because what I think it means is that if the bomb were to explode over the oxygen line the whole hospital could blow up. ... And that's just crazy, right?
