This is Parental Glideance, but with the rest of the Dash Family (In my headcanon at least)!

Same episode, same story, but for this version it includes Firefly (Windy Whistles' mother and Rainbow Dash's grandmare), Rainbow Flash (Bow and Blaze's mother and Rainbow Dash's 2nd grandmare), Rainbow Blaze (Bow Hothoof's brother, Windy's brother-in-law and Rainbow Dash's uncle), Sunshower Raindrops (Blaze's wife, Bow's sister-in-law and Rainbow Dash's aunt) and Pickle and Barley Barrel (The children of Blaze & Sunshower, the niece and nephew of Bow & Windy, the grandchildren of Firefly & Flash and Rainbow Dash's cousins). Furthermore, the Wonderbolts’ role is replaced with the Shadowbolts.

Headcanon:

Scootaloo is adopted by Bow Hothoof and Windy Whistles after her original family pass away.

Barley and Pickle Barrel are the children of Sunshower Raindrops and Rainbow Blaze.

Following after the poor treatment the Wonderbolts gave her in Newbie Dash, Rainbow quits the Wonderbolts and joins the Shadowbolts instead. Don’t worry, she doesn’t become a villian. For my headcanon, the Shadowbolts are real and instead of being performers or soldiers like the Wonderbolts, they are vigilante superheroes. This was based on an idea by King Grover: https://youtu.be/u003OBHXl7A?si=ySlJRi2lBCUSYqhk

The events of Season 8-9 (With the exception of The Washouts, Sound of Silence and Best Gift Ever) and Rainbow Roadtrip are not canon.

If anyone wishes to do a fanfic on this, by all means, go ahead! ^{^}
