The Great And Powerful Trixie has returned to Ponyville at last, and Twilight Sparkle doesn't stand a cha--hold on. What's this giant shiny house doing sitting in the middle of everything?
Twilight's just a little nervous. It has nothing to do with Moondancer taking over the Castle Library. Or Moondancer's smile when she suggested taking over the library. Or anything to do with libraries. It's nothing. Nothing at all.
After the events of "The Cutie Remark," Starlight Glimmer develops a new respect for Twilight when she discovers that they both have something in common: that they once had sanctuaries that were both destroyed.
