Apple Bloom has been chasing after Chip Mint for the longest time, and is distraught when she finds that he has already found himself a fillyfriend. Her fellow Cutie Mark Crusaders suggest that she try Featherweight instead, but Apple Bloom is uneasy, believing that him getting into a relationship with a simple farm pony like her could hamper his future career as a journalist. Tootsie Flute knows better, and tells everypony the story of how her two mothers, Lyra and Bonbon, were brought together.
This story was thought up long before Slice of Life, and contains plot features that contradict the aforementioned episode, hence the AU tag. I would have altered the storyline to suit, but this would have meant a complete rewrite as it was nearly half-done by the time the episode aired.
