The Doctor was laying there and smiled weakly. "Yes its nice seeing you." he deep down was a bit unsure. Jack was a fixed point in time now, he had actually ran away from him, It was against what was meant to be. But he didn't want to hurt Jack's feelings. Jack was still his friend.He knew Jack was pleased to see Rose as well. "Ohhh I'll be fine once I have the right medicine."
He coughed more and sipped his water from the bottle, he looked rather pale and looked ill. 
Jack was thinking, he was looking at what the medicine was on her screen "Ok should have some that at Torchwood, Though might have been one the medicines I took from our medicine stash."
He pulled out some vials from his pockets and looked at them.
