The Doctor himself is unsure of how to feel about all this. He knew it would be the Master showing up. Knew it from the moment of Adeola's warning passing her lips and that look of viscous intent.

And it didn't help what the Doctor knew. That the Master managed a horribly failed regeneration after this, and was so mentally unstable and far gone, the Doctor didn't think he was able to reach out to him. And then knowing he somehow had a part in the Doctor's own doom to come.

'They' said knowing is half the battle, but 'knowing' was far too much for the Doctor's taste. It was wrong and he wasn't suppose to know of his future; it went against everything a Time Lord stood for.

"Ignore him." The Doctor took Martha's hand and began moving down the hall, trying to distance themselves.
