He thought about giving another warning, but then realized it didn't really matter. The Master wasn't capable of listening, especially not in his current state and he'd already tried twice. All the frustration and ... aggravated surrender came back, full force. Besides, he'd wanted to do this, hadn't he? The timing sucked, but the Master didn't care and the Doctor had decided it just didn't matter.
The Doctor shrugged a bit to himself, and walked over to take the chair facing the Master. He reached out, curled one hand around the back of the Master's neck, spread the other against the side of the Master's face and, without warning or preamble, surged into his mind. Fast, hot, bright and everything he had pouring out to combat that damn ceaseless and maddening pounding.
