The Doctor looked up at the tall man that he knew to be his friend. " I'm The Doctor, Miss me?" he really didn't know what to say, he pulled out his sonic screwdriver. Knowing what Jack was like, he just blushed deeply. "Thought Id come visit you, " he grinned a little. There wasn't the deep masks of emotional pain like when he had last seen Jack, regeneration had made it easier to bury that pain deep. He knew Jack wouldn't have recognized him right away. He really didn't seem to know how to react around Jack, he was almost thinking Jack was going to hug or kiss him soon as he knew.
He really had missed Jack though, he was alone at the moment, but he seemed to try his best to stay happy.
