Joel: It's clear.
Tommy: [to Ellie] You want a hand up?
Ellie: I got it.
[Ellie mounts her horse as does Tommy.]
[As Tommy and Ellie begin to leave, Joel mounts his horse. He follows them a few feet behind. They tread at a steady pace through the forest. Joel is deep in thought, clearly thinking about what Ellie had just said to him inside the ranch. Eventually, they come in to sight of Tommy's settlement. Joel and Tommy near the edge.]
Joel: [to his horse] Easy..easy.
Tommy: [to his horse] Whoa now. [the two have stopped just shy of the edge. Ellie stops just behind them. To Joel.] There she is. Kids'll be watching movies tonight.
Joel: Where is this lab of theirs?
Tommy: It's all the way out - University of Eastern Colorado.
Joel: Go Big Horns. [he and Tommy snicker. To Ellie.] Ellie, get off your horse, give it on back to Tommy. [to Tommy] I'm gonna hang on to this fella, if that's alright with you. [to Ellie, who is too stunned to move.] Go on. Don't make me repeat myself?
Tommy: What are you doing?
Joel: Your wife kinda scares me. I don't want her coming after me.
[Ellie dismounts her horse and approaches Tommy, offering the reins which he passively takes.]
Ellie: Sorry for stealing your horse.
Tommy: [focussed on Joel] Look, come back to town, let's discuss it at least.
Joel: [as he pulls Ellie up onto the horse.] Eh, you know me. My minds all made up. University Eastern Colorado. How do I find this lab?
Tommy: It's in the science building, looks like a giant mirror, you can't miss it.
Joel: You take care of that wife of yours.
Tommy: There's a place for you here, you know.
[Joel nods in appreciation.]
Joel: [to Ellie] You good?
Ellie: [Content] I'm good.
Joel: Adios, little brother. [to horse] C'mon.
[With that, Joel and Ellie depart as Tommy watches them. End cinematic]
