I love this transformation. Let's face it, while I'm not saying Twilight didn't deserve it, her final test was not anything special. She had to fix a mistake she herself made, and did so through brute magic. It'd be like someone ascending through physical force alone. An interesting concept to explore (Like the Animatrix episode "World Record"), but we wouldn't root for them. Here, Trixie achieves it both through performing something that has never been done before, and through compassion
