He'd go to his room, but what would he even do there, sleep? Already had some, thanks, not looking forward to dreams tonight. Gym, then. Beat at a punching bag. Ignoring anyone else there who might stop to look at him. Get energy out. Practice. Move. Kick.

When stances, moves, motions that aren't his seep in, he gets unbalanced and ends up on the floor from someone else's footing that doesn't work on his body, his reflexes. Huffs on the floor until he picks himself up and goes again. He will keep going until he's sure he's himself. Or at least reasonably sure he's himself. At least he's got some energy out.
