[TEEN VERSION] Discord comes to Celestia, wanting her help to fix a problem. There is a Smooze in danger of attacking ponies! Celestia had no idea there was more than one Smooze.
It's been years since Discord had taken up a teaching roll at the School of Friendship. Now as a summer class, he's teaching on the subject of love - no one knows why.
Princess Luna is trying to find ways to remember the important ponies from her past, but is finding that it is difficult to maintain a perfect recall over the events of a long life. Then Discord gives her something unexpected to think about.
Intrigued by her brush with love, Sweetie Belle concocts a plan to find her a special someone. A plan that will need the help of Apple Bloom and Scootaloo.
A few years after Luna's return it seems that Equestria will finally know an era of peace and appears to be on the verge of a new renaissance. Ponies are happy. Luna is recovering. Celestia is miserable.
After being injured during the events of "The Ponies who Played with Fire" a now-captive Discord is facing trial for murder, while Fluttershy and her small band of allies are in a desperate struggle both to clear his name and avoid their own capture.
