I know we have tried this before and it almost always fails, but would anyone like to do a doctor who fanfic? I was thinking it could be about the doctor meeting a timelord girl and wondering where she came from, only to find out that she is the masters daughter, although she is not insane like the master because she is half human like the doctor, and she hasn't taken the test where the timelord child looks directly into the time vortex, so she hasn't had the chance to choose to stand, run, or go insane. of course there would be some companions for the doctor, as well as enemies.
there was an episode in which the doctor had his dna taken and was cloned by a group of soldiers who thought they had been fighting for years when in reality they had only been fighting for a few hours. so in technical terms he did have a daughter.
