The Doctor crash lands on Karn, when ship's pilot Cass learns that Doctor number eight is a timelord she chooses the fate of death rather then spend time with him.
I know Paul McGann only gets minutes in the role, but we are given a glimpse of how amazing he could have been if he's been given a proper stint, surely there could be a means to bring him back one day. I would also like to commend Clare Higgins, she's an excellent character actress, good that she returns in The Magician's Apprentice.
It was a huge surprise that Paul got to play the Doctor, even for a small part, and it look a wee bit recycled, but it wet the appetite enormously for the big special, 8/10.
