"Not sure 'because we've never seen it happen before' has ever been solid, scientific proof that a thing can't happen at all, but I guess I'll take it as a reassurance that it hasn't happened yet. At least it means nobody's figured out how to do it."

Maybe. Maybe not. "Still, I think I'm gonna keep my tinfoil hat handy just in case. Stuff's already weird enough here, I think anything could happen."
