Moons after their fallout and guilt, Princess Celestia jumps through the portal and finds Sunset Shimmer! Or does she? The girl she finds certainly looks like Sunset, but the girl claims to be just a simple musician who doesn't know Celestia at all.
After the stress of being a ruler and now teacher is becoming a bit overwhelming, Princess Twilight is offered a one-on-one holiday with Sunset Shimmer.
Sunset Shimmer finally crosses the portal to Equestria to visit her friend, Princess Twilight Sparkle. Twilight is very excited to show Sunset around town.
