A prank to the princess

You gallop as fast as you can back to Canterlot. Along the way, a masked stallion starts chasing you. You panic, trying to run faster, when suddenly it dawns on you: you can fly! While the pony who’s chasing you cannot. You soar back to Canterlot, a huge smile on your face. Disaster avoided!

Luna laughed. Things were back to normal ‘round here.
