Changing Desires

Princess Twilight had always thought of herself as a good friendship teacher. After taking Starlight Glimmer in as a student she really helped her grow in not only being able to make and keep friendships, but also in keeping her volatile temper in check. When Twilight told Starlight to go make a friend on her own, she did just that but it wound up being a pony Twilight disapproved of, Trixie Lulamoon.

Eventually Starlight was able to get Twilight to take Trixie in as a student but it did not take long for Trixie and Starlight to fall madly in love. This frustrates Twilight so much that she tries to plant the seeds of doubt in Trixie's mind making her think that Starlight doesn't really love her. When Starlight found out about this, she rewrote Starswirl's time travel spell in a different way. She took Twilight back to the day of her entrance exam and held filly Twilight in her aura. Starlight gave Twilight and ultimatum, give her relationship with Trixie her blessing or lose her destiny entirely. In the end Twilight chose giving Starlight and Trixie her blessing so Starlight let the filly Twilight hatch Spike and get into Celestia's school.

Now that everything has settled down, Trixie and Starlight continue their friendship studies but can it really be that easy for two marefriends to simply study friendship? Also, will it be easy for Twilight to continue to educate a mare who has much more magical ability than her, a mare who could eradicate her destiny if she wished?
