The Doctor was looking at her "I'm not been a sour puss," He grumbled. He knew he was only moody due to feeling unwell. He knew at least River knew how to fly the TARDIS. He was looking pale still, curling up in his blankets he went to sleep. He knew River would wish he was by her side flying the TARDIS, but he just wasn't up to it. His breathing was heavy.
When the Doctor awoke he groaned. He had a headache and hoped that he could hide it. Why did he have to go and get sick. The Doctor just hoped that River wouldn't notice, he sat up and attempted to get out of bed and he wobbled.
