Cristina: Is that Chest Peckwell? H-How is he?
Derek: Oh, a bad bleed. We won't know more until he wakes. What the hell happened?
Cristina: I don't know. Um, I need your help.
Derek: People keep saying that to me today.
Cristina: I found that on Paul Dawson's scan. Could that be a clot that we missed?
Derek: Yeah, that's exactly what it is. It's blocking blood flow to the basilar artery. Brooks... Why would we miss that?
Cristina: Oh, I'm not asking her.
Heather: Yeah, she's-- She's asking you.
Derek: And I'm asking you.
Heather (looks at the C.T.): Because it's a thrombus... which is harder to see. It's more common to find a bleed or an infarct. You were looking for the wrong thing.
Derek: Nice job.
Cristina: Could you take it out, like now? Run a pipeline stent and restore the blood flow to the basilar? I mean, could that wake him up.
Derek: It could. It could also kill him.
