The Doctor stayed quiet while they talked mostly, his eyes were closed. He wondered how easy it was going to bed for him to get out of there. He knew that he was horribly unwell.
He chuckled when he heard her on the phone to Mickey. He could see that she was definitely related to the Tylers. He found it rather amusing to listen to her on the phone as well. 
He knew that he would need to rest soon as he got a chance to.

The Doctor put the cold water bottle to his forehead as she gave it to him. He wondered if Mickey would know it was him, he knows that he had changed since he last saw him. He was hoping that between Caitlyn and him that Mickey would know it was really him. He closed his eyes for a moment.
Not been able to have medicine when he felt horrible was torture. He knew he had safer medicines in the TARDIS. Though it was just a matter of getting them.
