This is the story of how Spike got his wings, and became Sweetie Belle's brother-in-law. The story is enveloped within another tale of Spike's great-grandson, Uvarovite, and his special somepony, Dusty Amber, coming for a visit, many years later.

Part two: [link]

A caveat: the story does have a love scene in it towards the end (in part two). But it's not explicit. If this were a film, I's be aiming for something like an Adult Accompaniment rating... that is to say, you're in the room, you can tell what's going on, but the camera's in soft focus and aimed at the shoulders. My intention is to stir romantic feelings, not physical arousal. If you were alright with the love scenes in, say, Titanic, you ought to be okay with this.
