For some reason, Twilight and Rainbow Dash's friends think they're dating even if they show absolutely no signs of doing so! They were just really close friends...
It was supposed to be a simple spell. Not to interact or interfere, just to test. To reach out and see if alternate dimensions really existed. I didn't want to do it.
A few month ago, Rainbow Dash found Twilight stargazing up on the balcony of Golden Oaks library. Ever since then she comes back, every night, and listens to Twilight's lectures on everything astronomy.
Rainbow Dash teaches a preteen Scootaloo how to fly, strengthening their bonds, both to each other and the ponies around them. A story about love, family, and growing up.
