The Doctor was still a bit nervous. He looked at Jack, "Uh yea..." He sits down and he closed his eyes. He was unsure if the needle had be used just yet. He was humming to try and clear his mind, he didn't know why the idea of a needle was making him so nervous. He still had his eyes closed after JAck had even taken the blood and didn't seem to notice that it was over.
He was lost in his own thoughts right now.
