The Doctor was smiling when the TARDIS took off. He was glad that he was better. "I'm happy to be back," He told the TARDIS. He stroked the console and was thinking. He had no idea the TARDIS had found something more exciting and had taken them off the course they wanted.
He grinned. "Oh I missed doing this with so many people."
Jack laughed a bit "I Missed this too." He grinned more.
