[Jaime spares a moment to wonder why there would be a bunch of broken boulders way out here - not that it seems important enough to vocalize - mostly because it's never occurred to him to go out and bust up a bunch of rocks. Bart does pose an important question, and it's one that Jaime doesn't know the answer to, even if the truth of the matter has been hanging over their heads.]

Dunno. Maybe all that happens is you've got one best friend, and another good one. I know I'm not his replacement or whatever.

[If Jaime had to guess, he'd say that he and this other version of himself must be pretty different. He has no real desire to replace this guy he doesn't even know, this guy who has somehow become a monumentally important part of Bart's life.]

What d'you figure?

[It's an honest question. Jaime doesn't know what's going on in that head of his.]
