"Nope." That's an easy one, and it works on both counts. He remembers Sam (aka the guy who has a car, not that Alex is going to be mentioning that straight-up, oh no) mentioning a "Dean" and yadda yadda yadda, but he's not caught up enough on family drama to really care about that shit. "Never seen you before in my life."

Not that he remembers, anyway. He was here once before too, and it's kind of unsettling to be reminded of that here and again.
