The Master chuckled. "Very easy on the eyes. Especially on his knees." He sighed a little at the memory. He missed the Valiant. "I've run into one version of him here and I've heard there are others. The black medical student would be Martha - haven't seen her here yet though apparently she's here. And the Doctor... he's here goodness knows how many times over, but yes, there's one who may or may not be from my reality and a bit further on in the timeline."
He fell silent, gazing into space. The Doctor's words were finally starting to sink in.
