"Sure," he says, though he sounds a little less enthused by the prospect. It might be better to have some privacy, but what he actually wants is to see this Scully's initial reactions. Every instinct, every object that strikes her as relevant. Turning to the right leaves him on his own, wondering just what she's doing - and whether she's vanished.

But he does it, walking toward what turns out to be her bedroom. Mulder pauses at the threshold for several seconds, taking in the sight of it, before he turns and starts back down the hall. Once he's close enough to sidle up to Scully, the other Scully, he does. "Let's, uh, try it as a team for a little while."

Leaving aside the fact that he probably doesn't merit access to her underwear drawer anymore, he's not ready to uncover evidence that she's moved on completely. Not on his own.
