Why’s Iron Will put with the antagonists? He was just doing his job and it was Fluttershy herself who was the antagonist of that episode…That and pretty much everyone in Ponyville. {Was it national ‘Be a Jerk’ day?}
What’s next for Princess Twilight Sparkle? She will become Princess of Princesses on Princess Island and rule over all of them + Equestria, and then the world.
After that? The entire space time continuum as Princess of Space and Time itself.
