Lets say the Master, Four, Six, Eight, Ten and their respective companions are in a room.
"We should have an orgy." The Master stated from his small corner of the room. The occupants of the room ceased their bickering and cast wary eyes towards him.
Jacks immediate reaction was an emphatic yes (as that was his instinctual reaction to any question on the topic) remembered who it was who had made the statement, and immediately reverted to recoiled disgust.
Sarah Jane was giving him goggly eyes that were equal parts indignation and bewilderment.
Rose had her mouth wagging about like an outraged fish.
"That is absolutely disgusting!" She shouted after a moment. The Masters eyebrows went up as he looked her over.
"Well, you really wouldn't be part of it." then his eyes went back to where the four doctors stood, and he grinned at them.
"The Doctor would never! None of them would ever! Doctor tell him you wouldn't!"" Rose turned to her doctor, who was gaping at the Master with half glazed eyes.
"Doctor!" She demanded.
He looked to her, back to the Master, back to her.
"I..."
That was when the fifth spoke.
"Well he can stay out here then." and proceeded to head towards the Master, followed closely by four, six, and eight.
Suddenly ten was standing in front of the Master like a human shield.
"Back off! Ive been without for a hundred years so I get first dibs!" And then grabbed the Master and dragged him into the nearest room.

After several moments of silence Jack was the first to speak.
"You know, we could have a warm up orgy out here."

I like to think that it was Ainley, because Ainley saying any of this would make me happy.
