He blinked at how dismissively the teen mentioned all the space. Sure, the house was large enough but most of the rooms were occupied, so unless he was sleeping on the couch- or everyone had left. The way he froze at that revelation was probably more than enough evidence he knew damn well what that must have done to the other Ed's mental state.

The adult didn't respond when he mentioned Al naming Roy, taking a steadying breath at all of this news coming at once. If there was any doubt in the teen's mind that this was the same person he'd left behind in the Quarantine, the way he abruptly closed off at that point would have been plenty of indication. He swallowed, not looking at the kid as he spoke again. "Al's gone?"

He'd been trying to get him to leave for six damn months, and his brother refused to leave him behind. The idea that he'd left without Ed at some point in this other timeline was a little too much for him to process at the moment. If he had any idea how depressed the other guy was, he had to imagine that contributed to it. The part about Mustang might as well have gone unheard for all he was capable of registering beyond everyone being gone, including Alphonse.
