He could sleep in his underthings that are definitely not ridiculously patterned, but, sure, fine. Ex's sweats. From Bond's end, there's a flicker of...of something closed off but present. Not quite anger, but something dark. Possessive? Something along those lines.

He changes. The sweats fit, more or less. He does not know how to feel about that, or how to feel about the fact that he doesn't know how to feel about that. Better to just not feel, then.

All right. Fine then. Bed it is. But only because the brief views of Q's terror make him want to protect him from...what, from the boogeyman? From bad dreams, bad memories, maybe. If he can.
