So yeah, had this little scene in my head after I finished watching season 2. Rainbow Dash lives a happy life, although slightly crushed by never getting into the Wonderbolts. Scootaloo, seeing the pain her idol was in, became determined to fulfil that dream for her. so she grew up to become the captain of the Wonderbolts just to make Rainbow Dash smile.

Rainbow Dash is old
Twilight is old
Fluttershy has a granddaughter named after her
Fluttershy is dead
Twilight has a pegasus husband and an alicorn son
Scootaloo is loved
Scootaloo performed a sonic rainboom

Let the flaming begin XD

I also kinda entertain the thought of Scoot never getting her cutie-mark, becoming the most successful blank-flank in history.
