(Yurek, Twombly, and Nelson have reached the first crash site.)

We gotta go.

(taps Nelson to get his attention)

Shawn - Shawn, listen. Sergeant Yurek's gonna run first. Now, when he gets across the street, he's gonna turn around and he's gonna cover you as you run. Okay? Listen closely: when you get there, you are gonna turn around and you're gonna cover me. Okay?

(Nelson nods, then stands and gets ready to run.)

Now, you're not just gonna run to Eversmann's position. You're gonna stop, you're gonna turn around, and you are gonna cover me. It's important you understand that. Okay, you ready?

Yeah, I guess.

(to Nelson)

Hey - don't forget.

WHAT?

(with exaggerated enunciation)

Don't- forget.
