'Oh yes.' The Master smiled over at her absently as he further adjusted something on the screen before him. 'I'll be teaching you how to fly her as well. After we've travelled for a while, and you see how I do it.'

Growing another TARDIS was hardly as simple as all that, not with Gallifrey gone and the Matrix with it, but the Master was quite sure he'd be able to accomplish it. After all, there was little the Master couldn't accomplish if he'd a mind. Generating huon particles wasn't difficult, nor composing a solution in which a young TARDIS could grow, but finding sufficient psychic power would be a hard thing. A young TARDIS needed to be contained within a psychic net during its first months of life, and two Time Lords- especially one so young as Jenny- would hardly be sufficient.

But! Now was not the time to be considering that. Jenny wouldn't be getting a TARDIS of her own until she was quite a bit older, and certainly not until she had looked into the Vortex.

'I'm sure she appreciates your thanks,' he said rather wryly. 'Come here.' He gestured her over, indicating the screen on the console, which had switched to lines of equations and coordinates, showing where and when they were headed.

'Can you understand any of this? Any navigation included in your programming?'
