While cleaning the other's hands off, the Master smiled softly when the Doctor used his name. "I love it when you say my name." He whispered in Gallifreyan. Unable to contain that bit of excitement that always came with hearing it.
"They can try to kill me, but for some reason, I can't seem to do it right. Dying that is. A certain Doctor keeps me living. I doubt he'll ever stop." He said, almost more to himself than anything else. "And I'd do anything for him. Wasn't always that way. But right now... I'd rip them to shreds." He finished. He knew the pain of wanting something to stop, he knew it better than anyone. When the other grabbed his hands, the Master watched him carefully. "I'll find a way to make it stop, Theta. I promise." He whispered, trying to think of a way to stop them. To stop everything. Just like the Doctor had said he'd help him.
"It is. I'm here now, and nothing will ever harm you again. I bite. They won't want to come near me." He whispered defensively, still wiping blood from various areas. "It's okay. Shh now. I'm here. Don't make me kiss you." He finished softly, brushing one hand through the other's hair for a moment before moving back to wipe more blood away.
