The Doctor was dizzy and he lay there, he looked at Arwen "Jammy dodgers are good," He said simply. He wasn't thinking it could be that, He wondered what was affecting him, he knew that it was probably to do with the Master, he felt worse and ended up fainting for a few hours.
When he awoke he was looking around where he was. He seemed to be dazed and looked rather pale, he was shaking.
