1. I am Stormageddon

And thats as far as my knowledge goes, however I will attempt to create a story from the others below:

So Alfie creates a Bubble Sphere Gun that lifts the Tardis into an Anti Matter, permitted area. This is where the wedding of River Song is taking place. But she has forget her lovers name. The End... or is it?

While I doubt any of that actually happens, it's the best I can do :P
