After her magical battle with Cozy Glow, Trixie is mourning the loss of her favorite prosthetic wings. Mark Wells lifts a hoof, points behind her, and asks, "What are those then?" Trixie looks behind her and and spreads a pristine set of real wings reflexively.

This is a scene from our story, "Off The Mark", when Trixie ascends to pegacorn status. Not quite an alicorn yet but she has the potential.
