Shining Armor plans on throwing Flurry Heart off the Royal Tower to teach her how to fly.  Princess Cadence has some irrational objections to the idea, but Twilight Sparkle is going to provide important context for this educational experience.

No alicorn children were harmed in the process of making this fic. They had fun, actually.
