She would be, wouldn't she?

Beautiful and powerful and absolutely dangerous.

And all those emotions; the guilt about killing, regret for abandoning and hurting her father?

Gone. Not a trace left. The Doctor wouldn't even recognise her.

Of course.

Ah, now that is a victory against the Doctor. A decisive move in their neverending game. And, ooh, the Master popping by for a visit on one of the planets under Jenny's rule; and she's there on a throne, the cruel mistress, because one needs to present an image of some sort to the natives, after all. And he's found the Doctor there, and he just drags him before her, throws him down to the floor with a little smirk.

'What would you like done with him, my dear?'

Waits to see how long it takes for them to recognise each other.

We still need to do that someday.

Seriously.

We do. But, you know, this one far, far into the future. Ours would be while Jenny's still fresh, so to speak. And while Ten is still Ten. Just to drag out that torment a little more, because oh, isn't it lovely?

True. Doing it while she's still fresh and presenting the challenge of having to deal with her father would just break her and it would be terrific.

Eee, lovely
