He can feel the tugging on his hair, but just assumes that's her holding on since he's walking at a brisk pace back to his room. Brisk and not huffy, if anyone asks. Like he cares if a woman takes up residence in his hair until the loss wears off and she ultimately crushes him in his sleep. Why would that be anything to worry about?

When he exits the elevator at the exact same floor he was at a few minutes ago, he doesn't say a word of warning about the dog that hasn't been fed that they're about to visit. She may hear some barking by the time he gets to his door though, so it shouldn't be a complete surprise.

"You can keep him company while I take a shower." Dogs and fairies, should be fine. He just goes in and waits for her to fly off his head on his way to the bathroom. Maybe she can feed Ein while she's at it.
