The Great and Miserable Trixie

Trixie questions herself and her powers because of how she was possessed by the Mane-iac. With her magic prowess fading away, it's up to Twilight Sparkle to talk some sense into the magic performing pony and show her that she can still be great and powerful. Is Twilight Sparkle helping Trixie out of compassion or is there something more? Sequel to Gilda's Nightmare.
