The Doctor was looking at her. He just nodded. He knew that maybe he should just take a chance. But he still doubted he would met anybody who would mean that much to him again. He was still thinking over her puzzle.
He was tired still, he knew after a sleep that he would probably be able to work it out better.
"Alright have a good sleep." He yawned a bit.
He hoped she would get a decent rest.

He gets up and says goodnight to everybody before going to lay down and get some sleep. He was soon asleep. He curled up in his blankets. He was breathing deeply as he slept.
It was late morning the next day when he finally awoke. He heard Jack aruging with one of his team about something. He sits up rubbing his eyes. He guessed that somebody had done something wrong as normal.
