A couple of days have passed since Twilight Sparkle and Spike settled into Ponyville after the Nightmare Moon incident. However, Spike's noticed that she and her new friends, along with one or two others in town, have been behaving a little...oddly as well.

Not only that, but Celestia's summoned him back to Canterlot to inform him that he's now helping out her student in more ways than one...along with the rest of the Element Bearers.
