Castiel watches her as she passes through the lobby, he arrival caching his attention immediately, as she's the first person he's seen here yet. The antlers are odd but he thinks little of them--humans are strange and have strange ideas of fashion--and he decides to approach. She doesn't seem particularly threatening, though he knows he could be very wrong.

Still, he won't learn anything if he avoids everyone, and if she means him harm it won't matter if he approaches her first or not; she clearly knows he's here. So he lifts his chin slightly and steps a little closer, opening his mouth to speak.

And there's silence.

He freezes, confused, his neutral mask dropping briefly before he manages to affect calm again, and he tries to ask her where they are. Silence once more.

This is a problem.
