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: Through The Eyes Of Another Pony
Awesome Ego: Firewall's shameless arrogance is yet another of the things that make him so entertaining as a character.
This trope is ultimately subverted in chapter 8, where Firewall fails to stop The Nightmare from possessing Princess Celestia.
