Twilight screws up when making a complex potion, and ends up with two heads. With nothing to do about it but wait until the effects wear off, everyone involved is presented with a rare opportunity: finding out if two heads really are better than one.

I don't know. Once I had the idea, I had to make the image, and once I made the image, I had to write the fanfic. I already know my writing needs work (like, a lot of work) so constructive criticism is welcomed!
