Twilight is confused, very confused. Now this has happened before when she was trying to figure out the Pinkie sense, only now she has to deal with something that's a bit closer to home. Pinkie's distant cousin hails from a travelling circus from Stalliongrad, and he can perform magic even though he's an earth pony.

Now that's the part that bugs her. The rabbits out of the hat, the card tricks, the whole sawing ponies in half thing, it all goes deeper than that and Twilight is determined on discovering his secret. A secret so powerful it could perhaps affect the very fabric of Equestria itself… or not.
