It was late by the time McCoy sedated Jim, hoping to not only give the man a few hours sleep but to get away himself. He needed to find Shego, to make sure she alright or to keep her from Jim if she didn't know already. If he was being honest with himself he needed to get away for the very reason he was worried Shego wouldn't handle this well at all.
He slumped against the wall of the hallway for a few moments, letting out a breath he felt he had been holding for hours before he forced himself to start walking at a hurried pace. It wasn't just the way Jim looked, though that was part of it, it was the way he wasn't quite all there. There was a mad gleam to him that the other Kirk had in some ways, maybe not the same malicious shade but enough that his palm and arm itched with phantom pain just looking at him. Of course taking care of Jim came first, but now that he had the time to he wasn't quite sure why he wasn't falling apart under the sudden strain.
He stopped at Shego's door, brow furrowed as he knocked sharply. "Shego, it's McCoy." He called gruffly, like nothing was wrong because it was damned foolish to be so worked up over something that had been settled months ago.
