Hunter #1: [Far away.] "They haven't gotten back yet."
Joel: [Quickly ducks.] "Oh shit!"
Hunter #2: [Far away.] "What the hell is taking 'em so long?"
Hunter #1: "I don't know, they went to check on 'em. For now, we wait."
Joel: [Ellie climbs in through the window behind him. Whispers] "Come here. Keep your head down." [Ellie crouches beside Joel.] "Alright now...I'm gonna jump down there and I'm gonna clear us a path."
Ellie: [Looks at Joel] "What about me?"
Joel: "You stay here."
Ellie: [Frustrated.] "This is so stupid. We'd have more a fucking chance if you'd let me help--"
Joel: "I am!" [Momentarily looks over and grabs rifle.] "Now you seem to know your way around a gun." [Presents to Ellie.] "You reckon you can handle that?"
Ellie: [Pauses.] "Well, uh, I sorta shot a rifle before." [Takes rifle.] "But it was at rats."
Joel: [Concerned.] "Rats?"
Ellie: "With BB's."
Joel: [Reluctant.] "Well, its the same basic concept. Lift it up." [Ellie lifts rifle.] "Alright now," [Manuevers Ellie's position.] "you're gonna wanna lean right into that stock, 'cause that is gonna kick a hell of a lot more than any BB rifle."
Ellie: [Tilts head.] "Okay."
Joel: "Go ahead and pull that bolt back." [Preforms motion with hands.] Grab it right there." [Ellie grabs.] "Just tug it." [Ellie reloads.] "There you go. Now as soon as you fire, you're gonna want to get another round in there quick." [Ellie nods.] "Listen to me--if I get into trouble down there, you make every shot count." [Pauses.] "Yeah?"
Ellie: "I got this. I won't let you down."
Joel: [Nods.] "Alright." [Joel crawls away to an opening in the scaffolding but stops to look back at Ellie.] "And just so we're clear about back there..." [Pauses.] "It was either him or me." [Jumps down scaffolding.]
Ellie: [Stares.] "You're welcome..." [Takes aim.]
