When I wrote this story, I had the beginning and the end. Usually, when that happens, the middle takes care of itself as I set down to writing. This time, it didn't.
What I know about the middle is this:
The Doctor and Sarah, acting together and separately, would have stumbled around Storybrooke and begun to realize something was very wrong with this place. There would have been running up and down corridors and a couple cliffhanger endings (because Dr. Who) before leading into the final part.
Two weird things would have been going on with the Doctor. He would have found himself acting more and more out of character. I know there would have been a part where he would pull a gun on someone (probably someone threatening Sarah) and been perfectly willing to shoot if that person didn't back down –and maybe even if they did (if that had happened, I'm sure Sarah would have stopped him).
Through all this, he would have been having pains in his leg. It would start off as a twinge now and then, gradually becoming worse and more frequent. After the gun incident, he would have collapsed as his leg gave way and he found he had the same, crippling injury as Mr. Gold.
This would all lead up to the final chapter.
Except, well, what can I say? I never got the middle part going.
So, this is me officially giving up and going straight to the conclusion.
