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: Ponyville Goes Tothe Dragons
Actor Allusion: Twilight notes how odd it is that Ember's voice sounds a lot like how she sounded as a teenager. Tara Strong, Twilight's voice actress, also did Ember's voice in the games she appeared in.
Alternate Character Interpretation: Cynder. In canon, she's The Atoner who has a hard time getting over her past. In this fic, she's Jerkass who gets irritated easily by everyone who isn't Spyro, and has a problem with authority. (Though, that could be chalked up to being torn from her own world to one filled with Sugar Bowl candy colored ponies, and the fact that Ember use to have a crush on Spyro.) It also may be just a Jerkass Fašade she put up to form a barrier around herself in an attempt to forget about everything's she's done in her life.
Base Breaker: Of course, this coincides with the above. Some prefer this new characterization in comparison to how most fics tend to play up her past to wangesty levels, while others find her Jerkass demeanor a bit graiting.
