The Doctor was glad at least that he knew his name, it could be rather awful if he didn't know his name. It still didn't really ease much of the empty feeling he had. He wished he knew how to make that go away. He hoped he would remember things once his head didn't hurt as much. He really did want to sleep. But he was sure Samantha wouldn't let him, he really hated been so tired and not meant to go to sleep.
"Yeah I am a bit, Least have a coat I suppose" He said, he pulled it around himself more tightly.

He knew the idea of a police box spaceship would be weird to her, it was to him right now, But it was what he saw. He rubbed his head, he really did want to sleep, he was exhausted and hoped that he would be ok to rest soon. He was dizzy and felt rather miserable. He had no idea how he was going to stay awake. He was very exhausted and wanted to sleep.
"UGh so tired," He was glad at least he was going to be able to lay down. He followed her and was trying his best to stay up right. 

The Doctor was glad when he was at her flat, he lay down on the couch and noticed the tv was on. He was glad for the icepack on his head, It seemed to ease the pain and made him more relaxed.
"Yeah its helping. " he whispered. He was so very tired and shivered a bit. He groaned "Still feel bit sick, But sure I'll be fine, sure thats just part of it yeah?" He normally wpuld know, but it was like that knowledge was wiped.
