[I won't get left, don't be silly is what Will almost says. But of course, it isn't silly. There's no guarantee, after all, that they're even going the same place. What if there's some tiny, inconsequential difference between their worlds that they hadn't thought to mention, something like a discrepancy in Lucas's birthday, or a slightly different sequence of events, no, we went to the movies and THEN the arcade that day last May, don't you remember? that'll result in the Mike he sees upon waking up being a different Mike? Not his Mike?

It won't really matter, Will knows. Whichever Mike it is won't remember Deerington, and neither will he. But like this, standing at the edge, he's suddenly thinking of all the worst possible outcomes.

To distract himself, he looks away from the door, looks at Mike instead. Squeezes his hand and tries to put into his own awkward, faltering teenage words everything brimming in his chest.]

I know. I -- it's not going to change. For me. No matter what happens, no matter what you...do or don't do or say or don't say. [He exhales, looks down at their entwined hands, burning them into his memory.] It didn't change here either. [No matter the fights or the failures or the myriad ways Mike's picked himself apart and found all the flaws.] Okay? It's -- always been you.

Okay?
