He listened carefully to her response. Of course, her voice gave away nothing, but the choice of words she'd said made him think perhaps there was something more deeper inside. If that was true, then Svetlana had a lot of resentment towards someone, or perhaps more than one someone. Well, that could be interesting. The more people she could lash out at, due to his meddling, the better. He did like leaving chaos in his wake. There had only been one fight he'd truly run from, and that was the Time War. Romana had chastized him for running, for abandoning their people to their fates. But the Master had seen untold horrors on the front lines of the war that frightened even him. He recognized fighting would only mean suicide, so he had run to the end of the universe and hid there. He'd fob-watched himself, making himself human with no recognition of the Time Lord he had been, the one that was sleeping within. Then that lovely Martha Jones had come along and woken hi up, unleashing him on the universe once again.
Now he was here, ready to unleash terror upon Earth, and mess with Svetlana. As she said check mate, the Master looked at the board. Well, he certainly hadn't seen that coming. He'd been too focused on making his moves and planning his approach of Svetlana to have seen the opening he'd left. But that was the Master, he had a tendency to leave holes in his plans and he tended to get thwarted because of that. But this time, losing the game was a positive. It solidified that Svetlana was worth his time.
"Well played, Svetlana," he said with a smile. Now, to use hypnosis or out-right domination? He settled for the hypnosis. That way she'd tell him what he suspected lurked beneath the surface. Then he'd turn her around and let her act out against whatever it was. He looked up at Svetlana, the smile still on his face. There wasn't anyone else in ear shot of them, so he had no fear of what he was about to do. He looked her in the eye. "I am the Master and you will obey me." As he spoke the words, he reached out with his mind to take hers away, take away her ability to resist him and do whatever he wanted. He put her into a trance, but he waited to make sure she had no defenses, no counter move for being hypnotized.
