Maria: "Don't even think about reaching for your weapon." [Ellie draws her gun.] "Tell the girl to drop hers. Now!"
Joel: [Backing up.] "Ellie, do as the lady says."
Ellie: [Reluctantly raises her hands.] "Okay..."
Maria: "Please tell me you're lost."
Joel: "We didn't know the place was occupied. We're just trying to make our way through."
Maria: "Through to where?"
Tommy: [Off-screen.] "They're alright."
Maria: "What, you know these people?"
Tommy: "I know him" [Camera pans to Tommy, holding a rifle, opening doors.] "He's my goddamn brother."
Joel [Smiling.] "Tommy."
Tommy: "Holy shit" [Embraces Joel.]
Joel: [Chuckles in disbelief.] "How you doin', baby brother?"
Tommy: "Let me look at you." [Pulls away. Chuckles.] "You got fucking old."
Joel: "Easy--It's gonna happen to you too."
Tommy: [Maria walks beside him, still holding her rifle.] "This is Maria. Be nice to her, she sorta runs things around here."
Joel: "Ma'am. Thanks for not blowing my head off."
Maria: "Would've been embarrassing, considering you're my brother-in-law."
Tommy: We all gotta get wrangled up at some point."
Maria: [Looks at Ellie.] "Ellie, right?"
Ellie: [Nods.] "Yeah."
Maria: "What brings you through here?"
Ellie: "Uh...it's kind of a long story."
Tommy: [To Maria.] "Why don't we bring 'em inside?"
Maria: "Yeah. [To Ellie.] You hungry?"
[Maria enters the dam while Ellie and Joel follow. Tommy closes the door behind him. End cinematic.]
