Between a rough fill-in on the details of their situation, general fluttering about aliens, bunking the absolutely no possessions he had in with Sean, and actually grabbing food, a shower and sleep, it had been a busy sixteen or so hours for Alex.
He was still tired when he woke up (too early; he wakes up on prison time whether he likes it or not), and he'd gone for his usual run in a pair of Sean's ill-fitting shorts and t-shirts (the shirt is too small, the waist of the shorts fit but the legs are too long) because he didn't know what else to do. The fact that he'd almost literally bumped into Erik on the way out the door seemed--familiar, if not like home, even if they hadn't said much to each other. ("Good to have you back." "Thanks.")
By the time he gets out of the shower he can hear people stirring around the rest of the manor, and smell food from downstairs. (Real food, that was a change, too. Food he didn't have to guard from anyone, food he could even have seconds of if he were feeling really crazy, although he almost never did.) He throws a pillow at Sean's buried red head and feels absurdly good for a second--maybe it's not home, but maybe some things he can count on, like the fact that Sean could sleep through an air raid siren. "If you're not down there in five minutes I'm gonna come back up with ice," he warns, lovingly.
In the kitchen he's briefly slowed by the presence of an unfamiliar girl entwined with Raven (a pretty girl, he thinks absently, because he's not a monk), but: again, some things don't change, and the first thing he is programmed to do once he's in front of food is eat it as quickly as possible in case some dick comes along and flips your tray for no reason.
