Twilight's eyes widened at Discord's voice, and she whirled around. "Discord...!" She spread her wings, flying up a bit to be level with the Draconequus' gaze. "How could you have done something like this? You said you'd changed!"
Mystic frowned at that. "Oh, that's horrible! I can't see why they'd do that - you're just a different kind of Pony. I mean, honestly - Pegasi, Unicorns and Earth Ponies all live together, so why can't they live with a..." She glanced briefly at her fangs and wings, thinking, then spoke again, "Bat Pony?" She asked, smiling sheepishly. "Is that what you'd be called?"
Twilight narrowed her eyes, then her voice raised to a shout as she responded, "And what about Fluttershy then?! She thinks that you're friends! She's been trying so hard, and you're just going to ignore that because you 'aren't a pony'?"
Mystic nodded. "What's it like being a Bat Pony, then?" she asked, then added, "Other than the whole, every other pony fearing you thing, that is..." She gave a soft, sheepish laugh, moving one front hoof over the other foreleg.
She growled faintly, moving slightly as she looked at Stonewing at Discord's order. But she quickly turned her attention back to the Spirit of Chaos. "You aren't going to get away with this, Discord. We won't let you turn Equestria into... whatever you're trying to turn it into!" Despite her words, subconsciously she knew that she couldn't bring herself to tell Fluttershy about this betrayal. It would crush her...
She tilted her head, then giggle slightly. "Heheh, I guess so!" She shook her head. "Do you have any special skills other than flying, or are you really not different from a Pegasus?" She asked another question, wondering if she could maybe make it so that the Bat Pony was more accepted.
