Scootaloo based on the My Little Pony: Friendship is Magic TV series. This story takes place during season 8. The season acts as a backdrop or is notably changed throughout the chapters. Parts of this arc take place during the Washouts episode.

Scootaloo finds out from Rainbow Dash herself that Rainbow is a master mev early on in the arc in a scene similar to the  opening of the Washouts episode. Her CMC friends learn about their sisters being fledgling mevs too.  The three are allowed to discuss the matter among each other though are encouraged to keep quiet about the matter otherwise. Scootaloo catches on that Sweetie Belle is warming up to the mev stuff more than she is while Scootaloo herself is mostly confused by it.

Rainbow Dash and Scootaloo still go to the Washouts show together. While there are several similarities to how the real episode played out with some lines directly lifted from the show, there are also notable differences. There is no going to Spitfire or Rainbow Dash tearing up Scootaloo's Washouts merchandise, for instance. Instead, the two have an intense conversation where Scootaloo admits her disability, Rainbow offers to try and help with it, but Scootaloo decides she wants what the Washouts have to offer.

The whole thing will still lead to Scootaloo trying to perform with the Washouts. Another scene again plays out very similar to the actual episode of the next Washouts show with Scootaloo growing nervous and being in genuine danger from the stunt she is supposed to do. Rainbow still swoops in and saves her. Instead of cutting to a scene of a Scootaloo fan club, this story (and arc) has Scootaloo accept Rainbow's offer to try and find a cure for her disability.

Context and italicized audition lines:

0 - [Context: Scootaloo is hesitating on believing Rainbow Dash's very recent confession to being a vampire, but Scootaloo can tell there seems to be a subtle difference of some kind in how Rainbow is acting.

"But...it's daytime. You don't look or act...well, okay, you act a little different, but it's not very vampire-ish," Scootaloo pointed out.

1 - [Context: Scootaloo is being defensive after Apple Bloom and Sweetie Belle have expressed doubt that he is even still a fan of Rainbow Dash. She still likes both even if she's more into the Washouts at the given moment.]

"I'm just into them a lot at the moment. It's different," Scootaloo insisted. "In fact, despite everything, Rainbow's actually taking me to see their show this weekend. I'm going to show her why they're super awesome. She'll understand."

2 - [Context: This is from one of the more dramatic scenes in the story where Rainbow Dash and Scootaloo confront each other. Scootaloo has admitted her flight disability. She is skeptical of Rainbow's offer to possibly find a cure and knows she wants to perform with the Washouts tomorrow. This line should still not be delivered to the point of melodrama, more like subdued determination.]

"Then we're right back where we started, aren't we Master Rainbow Dash?" Scootaloo pointed out. "I don't know about this offer, but right now, I know that I want to perform for the Washouts, with or without your approval. I know that I can't fly today or tomorrow, and that I have a chance in this moment to do something important to me. I'm my own foal now, and you can't stop me."
