The magic seems to be doing something to your insides. Everything hurts in a horrifying fashion. You apologize for chasing the pony and beg for forgiveness in weak tones, barely able to scrape the ground.
The pony glances off, ears swiveling away from you towards some sound perhaps. "That's... too cruel... Goodbye." She turns tail, literally, and dashes off, her hoofsteps receding into the distance.
Despite any desire to sit up or do much of anything else, your body aches and shifts uncomfortably. Whatever she did, it seems to be settling down. You hear something, steps, footsteps. "We have someone over here," comes a male voice. You hear boots sliding down the same valley you came down to just beside you.
The police have found you. They take you to the nearest hospital to be checked up on and, at least, you aren't given a huge bill for it. Alas, you don't get any ponies out of the deal at all, just painful memories.
