Still care - The Master is trying to Track down the Doctor but has a stomach flu and is struggling, but he is still determined. He though collapses and the Doctor helps him
The Master walked or rather stumbled trying to track down the Doctor, he felt awful, but making the Doctor suffer was still more important to him. Though he didn't want to shame himself by vomiting in front of the Doctor, he wondered if he should wait till later or put his plans aside for another day. But he just shook his head.
He knew he could fight this, he coughed a bit and moaned. Damn he thought, the drumming in his head already making his headache feel worse.
He looked around trying to look for signs of a blue police box, he knew as soon as he found that he had would have found the TARDIS, and where the TARDIS was the Doctor was likely to be. He looked annoyed when he was feeling dizzy, his head was pounding and he he was burning up. He coughed a bit and walked on more. He knew he could get there. When he heard the sounds of the TARDIS near by he smirked.
"Finally," He laughed a bit and tried to run there to make sure the Doctor didn't get away from him. He waited for the Doctor to step out. He knew the Doctor would be determined to try and help if saw he was sick. That mere fact made him feel even worse.
He coughed again and sighed as his stomach lurched, Not now. He thought irritably.
