Something's wrong with Twilight's new student, the redeemed villain Starlight Glimmer

Even though Starlight been forgiven for everything she's done and been made a member of Twilight's distinguished circle of friends, something's obviously troubling her. Even a Pinkie Party thrown in her honor isn't enough to cheer her up.

Troubled, Twilight has a little mare-to-mare chat with her new friend/student, only to be bushwhacked by a simple question: "Why?"
