Hours had passed. Hours. The Valeyard was now sleeping. The two weeks that the Doctor had rested left him awake, energized. There was more than an hour in him, now, though he didn't know how long.
He reached to his side table and flipped a switch. Lights flickered around the ship, and a few of the cameras turned off. The damage done would leave the Valeyard angry, but it would keep the Doctor and the Master safe. For now. It wouldn't be long until the Valeyard worked it out, and the Doctor knew it.
So hard, sharing one body. The part of him that wanted to stay the Doctor remaining safe and secure in a small section of the tyrant's mind.
He got out of bed and slipped down the corridor, avoiding the cameras he knew were still on as he made it to the infirmary. No guards. They were switching out, now. He had a window of opportunity to make sure the Master was safe. He had to make sure. He had to see that the damage the Valeyard had done wouldn't be permanent.
He pulled open the door and stepped inside.
