Heather (about Jason): What happened?
Alex: What does it look like?
Derek: Brooks, what do you see?
Heather: Like someone super messed him up.
Derek: Talk like a doctor.
Heather: Um, temporal bone fracture with an epidural hemorrhage.
Derek: How soon does the bleeding need to be evacuated?
Heather: Like, yesterday.
Derek: Yeah, book an O.R. Let's get him up there. (Heather walks away) Karev, what the hell happened? Who did this?
Alex: Make sure he doesn't die. You can't let him die, okay?
