Oats and Strawberries

A few generations hence, Spike is visited by his great-grandson, Uvarovite, and his fiancee, Dusty, and tells the story of how he won his wings and the heart of Uvarovite's great-grandmother, Rarity.

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.
