Jesus guys, you've got no idea how bad I felt for Twilight at this scene. If I were my OC, Firebolt Blitz, I would've gone over to here, and gave her a good long hug, because I knew she had never set a hoof wrong before, so how could she have been wrong now?
Unfortunately, as much as I am a sympathiser, I'm also a realist. Twilight burst in at the worst possible time, and started accusing the bride of her brother (and a princess, no less!) of being evil, with absolutely 0% proof to back up her claims. Shining had every right to be peeved at her, however I still feel that the way he went about it was way too harsh, and her friend's and Celestia's actions that followed were simply unacceptable. Celestia should've known Twilight better, in all her wisdom, and her friends should've also known better than to just trot away from Twilight like they did.
Her face says it all, doesn't it? The lower jaw going below her chin, her mouth crooked in pain, her eyes wide in shock, and her ears pointed sharply downwards..........the picture of a shattered soul. It just goes to show how much Twi loved and cared for her brother, her friends and her mentor respectively, and for them to just shun her like that.........that is a coldness beyond comprehension.
God damn you Chrysalis, and all of your Changeling ilk.
