These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ace Combat: Equestria Chronicles
Chaotic Neutral: Gilda. Type IV: she doesn't fight for anyone or anything, but herself.
General Silverbeak appeared to have crossed it by suggesting a plan to kidnap little fillies and using them as hostages in the early phase of the war. It is revealed in chapter 14 that it was actually Red Cyclone's idea.
Gilda's betrayal and her brutal beating of Rainbow Dash in chapter 11.
Nightmare Fuel: The second chapter of Wings of Unity has the heroines discuss how Aurora managed to get her wings. She got them by combining magic and alchemy, or, to put it bluntly, using the blood and bones of her fellow Exiles, be it those who died or would die soon.
