[His lips purse at the question. Evidently they'd known each other here as well, and Dean can't say for sure whether that's good or bad. On the one hand, they'd gotten along more or less alright in Wonderland, but there he'd been tempered by months of stabiliy, months of growing to give the residents of the mansion the benefit of the doubt. They'd all been stuck together after all, they'd had a common enemy, a common cause, and he'd gotten a little more face-time with monsters of the vegan variety.

There's no guarantee things had been the same on the ship. For all he knows, the last version of him could've found out Derek was a wolf the hard way, could have hunted him down and threatened him, could have walked in on him during a change, could've done any number of things to start it off on the wrong foot. He'd have been sure he was making the right call at the time.

Derek seems neutral enough, though, so maybe they'd gotten along. Who the hell knows.

He scratches absently at the stubble beneath his ear, ambling a little closer before drawing to a stop a few feet away.]

That last guy- I'm not him. Memory wipe or... doppleganger swap, I don't know, the point is I don't know you from here. I showed up fresh-faced about two months ago.
