The Thirteenth Doctor

Here's my ongoing very AU take on what the ending of Death in Heaven could but probably won't be like. It's just a lighthearted little story so take it for it is. Here's how I think that Twelve regenerating into a woman just might go and I hope that you'll like just who the Thirteenth Doctor turns out to be. Here's a hint. She's someone who is already very, very familiar to us all!
