Shortly after the Nightmare Moon incident, Celestia tries to help her sister get adapted to modern Equestria while Twilight and friends continue to work to know one another.
When Twilight's portals release Tirek into the human world and the humans get turned into ponies, they have to unite with their ponyselves to defeat him and save both world's.
Meadow Flower attempts to cheer up Spike after she and Cloudchaser witness Rarity reject him. Things pretty much snowball from there when Meadow Flower finds herself interested in the dragon.
When shes sent to help set up a town hosting the Summer Sun Celebration with another student of Celestia's, Twilight is forced to tolerate Sunset's jokes and more in order to save Equestria.
Cancelling practice is a huge taboo for Spitfire. Sadly, piss poor weather might force her to go through with it. Truly, there is no worse fate than an unscheduled day off.
(Takes place sometime after "Rainbow Falls".) After word gets out about what happened with the Wonderbolts at Rainbow Falls, the elite flyers' reputation starts to slide. Spitfire considers resigning, and Rainbow Dash struggles to talk her out of it.
As Hearth’s Warming approaches, Rainbow Dash seeks Twilight Sparkle’s assistance in retelling an adventure story in an effort to bring back the sister she never knew.
