Kyle is following closely, a bit like a Scooby Doo sneaking sequence, but mutters to himself a moment for the jab, "A jiffy is one one-thousandth of a second." He squeezes his eyes shut for just a blink before looking away again, "Sorry..." He just can't hold the science in.

But Kellen is looking at him, (really looking. who does that? no one really looks), and his hopes climb just a little in knowing that maybe he wasn't making fun and really wanted to know, "String theory says that all possible timelines and universes happen simultaneously, instead of parallel. In a matter of speaking." There is a twitch of lightly-freckled cheek in a half smile, "So, the answer is, sorta."
