One year ago the Doctor landed in Equestria after falling into some sort of rift. There he met new companion and friend Derpy while taking the guise of Ponyvilles timekeeper 'Doctor Whooves'. But one day while planning a trip to the past something happens.

With time changed and a mysterious but familiar force pulling the strings from the shadows can The Doctor save the day and fix the timeline?

The key to doing so may lay with Twilight Sparkle, but the she's not the Twilight the Doctor knows.
