The Master doesn't really want to save the human but he finds himself toppling the cyberman anyway. Perhaps it's because the Doctor would be quite annoyed to see his pet dead even after they had attempted to fix her or perhaps it's the promise of information from her and the entertainment he can gain over the years he has to wait until he can reach the Doctor. Either way the human is saved for a moment and the Time Lord is going to make the most of it.

A pet human might make a good distraction for a while.

He lures her from the room with promise of tea, briefly wondering whether everyone on Sol 3 liked tea or the Doctor only chose those whose tastes matched his own. I mean- he himself was partial to tea but from those he had met it seemed it that was something that the whole human race shared without discrimination. Perhaps they had all been brainwashed- then again if they had the Doctor would have done something about it. Or would he? What's the harm in a liking for tea?

He checks the hall briefly- it wouldn't do to have to get rid of the nurse so soon- and gestures for the human to follow him. The Master remembers then how the Doctor's type involved compassion.

"It's alright- they don't feel pain." He says simply, waving the human's concern away.

The human contradicts him and the Master only just manages to fight the urge to roll his eyes.

"Yes they do." He admits, trying to fake concern and failing quite miserably. The human- possibly female, maybe? He's never been sure- questions him again.

"It was a clever lie." He whispers, "But you see straight through me." He shrugs as he finishes before attempting to derail the human's train of thought with tea again.

Yet again the human questions the Master and he wonders if he should have just let the nurse or the cyberman deal with it. Humans were fragile with endless questions and he is already tired of this one.

"People, people, people, people, people. They are people." He says, patience nearing its limits and just wishing that the human would give in so he could start pumping it for information. The information on how to distract the other aliens travelling with the Doctor would be more than enough for him to spare its life for now.

She finally asks a relevant question and he can't help but smile.

"Curing them." The Time Lord declares- running off before the human can ask more questions. He checks that the human is following before going to find the tea- he knows he put it somewhere around here.

The wheels of the drip squeak as the human enters the room and pauses. He steps out in front of the primate and tries to hide his amusement at the fear that flashes through its mind.

"You want the good tea or the bad tea?" He asks, pretending not to notice the physical symptoms of shock. The human recovers quickly and asks the difference.

"I call one good, one bad." The Master admits easily. The human seems confused by the answer but asks for the good tea anyway which is lucky for it because the bad tea is actually really terrible tea- he honestly can't remember where he got it.

"Excellent- positive attitude will help with the horror to come." He says, instantly going to make tea. The Master turns back briefly at the human's question.

"Mainly the tea." He says with a smile. It's not entirely false- even the good tea is more strongly mediocre to bad.

The Master sets himself to the task of making half-decent tea and mentally sighs at the indignity this adventure is forcing upon him. If anything that human of the Doctor's should be making half-decent tea for him upon threat of death.

He reminds himself of his main goal and commits himself to the long haul.
