The partial turnaround of my TYT Cozy Glow design.

The implication of her being here is that after being in fucked stone jail for some time, Flurry decided just a regular remedial sentence would like…actually solve any problems with Cozy far more than keeping her in stasis till the end of time (or until the next pony in charge has to deal with it, y'know the Celestia Method).

After her release though, they discovered that her taking in an insane amount of Discord's insane magic in the past led to her developing some of the attributes of her chaos form, making her an odd artificial nocturna. Twilight believes there's still a small amount of that magic within her and she may still be capable of higher arcane magic than the average pegasus, but no one's been brave enough to test that theory yet.

She doesn't seem to be capable of any abnormal amount of magic, the worst that's happened is her eyes glowing, her voice distorting, and her hair flowing like her chaos form whenever she's emotional.

Even though she has gotten better, it's easy for her to still slip into her more heinous behavior. She tries to dial back any more monstrous traits, like keeping her eyes hidden and her wings covered. Especially since nocturna are ever rarer nowadays than they were back in her day. For now, Twilight has to put trust in her, because her niece trusts her, but that doesn't mean Twilight has to like it. After all, Flurry's always by her side, in more ways than one.
