The Master led the way to the bar, but glanced back at the Doctor over his shoulder several times as he did. Partly to make sure he was following, because now that he'd finally found him he wasn't going to let him disappear if he could help it, and partly because... something wasn't right. His conversations with the other Doctor and Master came back to him with a jolt.
"You all right?" he asked, as they approached the bar. He made the question as casual as he could, because he didn't want to frighten the Doctor off.
