McCree thankfully doesn't know about the blurry lens part, and he raises his brows in an impressed expression.

"Well that'll make things a whole hell of a lot easier for you." Seriously, how ideal is it that he ran into a skeleton that doesn't need to breathe underwater and can see in the dark with his probably magical tool? And also isn't Sans, who would probably snark about the situation, ask what was in it for him, and suggest getting paid for it. (The irony that McCree might do the same if this was a situation that didn't interest him is not lost on him.) Win-win.

"Name's McCree, by the way."
