The Doctor opened his eyes slowly and he looked around. He was wondering what the TARDIS would come up with he was nervous again. He felt rather dizzy suddenly and had to lay down on the bed, he didn't realize that the Master had purposely made sure something got into the TARDIS to harm him. He closed his eyes again. He had no clue what was going on really.
"Jack.... think something..... is harming me."
He was too dizzy to even think.
