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: Predators Moon
Awesome Art: All the cover pages that the author made for the story are very well-drawn.
Harsher in Hindsight: The library burns down in one chapter, only to be restored to perfect condition the next. Too bad they couldn't pull that trick in the Season 4 finale...
Celestia trying to kill the Predacons in a slow and painful manner.
Twilight's Heroic BSOD can count as this, especially seeing as she's in a corner with no lights.
Pinkie Pie coming across Tarantulas in Derpy's basement, with not only Derpy strung up but Dinky and Amethyst.
During the fourth chapter, Carousel Boutique gets attacked by Dinobot II. While Rarity is holding off the Predacon, Sweetie Belle runs away and tries desperately to find help even though everypony she meets is scared. Blackarachnia on the other hand...
Also counts as Adult Fear when Dinobot II holds Sweetie Belle hostage in order to get answers from Rarity.
