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.
Crazy Awesome: Pinkie Pie, as in canon, though here she also does things like borrow the chapter outline from the author and do things so crazy even the dragon magician is perplexed as to how she's capable of it.
The Woobie: Applejack in Spells 4-6, particularly when we find out she's so dead set on keeping the farm going because of how much it meant to her deceased parents, particularly when Gnome lights half the farm on fire.
Jerkass Woobie: Gilda turns out to be one when its revealed that Djinn has spent the last six months systematically tearing her life apart and framing her for crimes, and that Rainbow Dash is basically her last hope.
