The Doctor was laying there closing his eyes. He knew that he needed to rest. The time lord had no energy. He wanted to conserve his energy if he could. He wasn't sure when everything would be over.
One of his hearts seemed to be struggling. It seemed the ceatures had done more to him.
"Stay safe," He trailed off. The time lord was shaking.
What ever was wrong was taking its toll on his body. He didn't want to die. He knew he had no more regenrations.

Though the Doctor was still unsure if he was dying or not. He just was feeling worse as time went on. He stayed slumpped in his chair. He closed his eyes still and was thinking of the past. He had been through so much with the MAster. He didn't want it to end at just this when he finally had his Koschei back.
He was shaking more. 
He seemed really unable to keep himself relaxed. He was shivered more and more.
"Master..,." He whispered more.

The Doctor didn't want the Master to leave him in the TARDIS, but he knew he couldn't stop the Master from going after the creatures. He had a feeling the MAster would kill them, He just couldn't barely even move.
He was just too weak to move.
The time lord ended up falling asleep. There was nothing he could do when the Master was out there stopping the creatures and he was stuck laying weakly in a chair. He seemed very pale. He breathed deeply.

When the Master returned, he saw the blood. He coughed and tried to get up. "What did you do!!" he growled angrily. He gasped and fell back. He wasn't feeling good, his heart had slowed. He knew he may only have 30mins left. Though too him that was alot of time.
He had been used to having limited time. He coughed more as he struggled to breath.
The time lord knew that creatures had made sure that they had given him a fatal attack.
"I think this was fatal." He groaned. His hearts were now both slowing, He gasped weakly in pain.

The Doctor was groaning and he rolled to the side and coughed up blood. He was shaking and whimpering in pain. "Koschei." He knew that the Master hated been called that, but he felt more vunerable now.
He held his chest and tears went down his face. He had no idea what was been done to him. BUt now he was sure that he was dying. It didn't feel like he was going to be ok. The time lord needed the Master to help him.
"Help me...," he said weakly. He had never said that often to the Master.

He was closing his eyes. It was getting harder for him to stay awake. He held out his hand to the Master. He wanted to feel the Masters touch. He coughed badly. He was still mad with the MAster.
But he didn't have enough time to aruge really. He thought maybe he would if he surived,
One of his hearts gave out and it was getting close for the other one too.
