Ford is damn certain that if he gnaws on the inside of his cheek any more, he's going to draw blood. He keeps doing it anyway, though, because it's a little less obvious than chewing on his lip, and he really doesn't want Stan to know how hard it is for him to think all of this over without looking as anxious as he feels.

He's only quite for a few seconds (though it feels much longer than that) before he takes in a deep breath through his nose and releases it through his mouth. He's gotta psyche himself up for this - there's no way Stan won't look at him like a goddamn idiot after he tells him, he knows that, he's convinced of that, but at least he can prepare himself for it since he knows its coming.

"...Do you remember when we were kids, and I used to make you watch all those cheesy sci-fi movies about time travel and parallel universes?"
