"Soooo...what you're saying is it's possibly them traveling through times but also possibly the worlds they pull people from are different but superficially match times in other worlds' pasts. And it could still be either/or but functionally it means I'm just like people from your past anyway."

"Which is basically what she just said. And basically what I just said. Only in way more words. Okay, got it."

Except that didn't sit well with him.

"Except what if I'm not from your past? What if I'm not from your past and my present is a little different from your past? You shouldn't just assume it's functionally the same just because I seem like something from a past that sounds like it's way too far in the past for you to even know anything solid about, anyway. Especially if turns out we're in the same present and it's an entirely different world and the way people live in it might be its own unique..." He waved vaguely with his hand. "...thing. Like, did the people in your past do bear-owl racing for fun? Or, I don't know, listen to rock music?"

Guy couldn't take credit for rock music, that was all Grug. It basically consisted of hitting rocks on other rocks rhythmically in a way that was fun to jump around to.

In any case, Sherlock had just given Guy his own chance to talk their ears off. Now that he'd gotten Guy going with the philosophy and trying to figure out the universe, he wasn't going to stop anytime soon. At least not unless someone else stopped him.
