• Pinkie and Fluttershy do what they do in the name of protecting the citizens of Equestria. Pinkie ended Red Pill's life to prevent him from drugging and having his way with anypony else, and Fluttershy stands up for all the foals who have been sexually abused by Teddy Bear, with irrefutable evidence in the form of a book of photographs.
  Fluttershy: Adult ponies think that because little foals are helpless, they can do whatever they want to them. Hooves all over vulnerable bodies. Big voices telling them how much trouble they'd be in if anypony found out. Of course, it's the adult that would be in trouble. But the foals don't know that.
• What exactly does Spoiled Rich do to provoke Fluttershy's wrath? Upset Pinkie Pie. One can't help but see a parallel to Pinkie refusing to prank Fluttershy on the grounds that she's sensitive, then hating Gilda's guts when she makes Fluttershy cry.
• Given what we know of how Spoiled Rich abused Diamond Tiara, it's nice to know she can never hurt her or anyone else again.
• In spite of her crimes, and theirs, Fluttershy comforts her victims in their dying moments (except Chrysalis).^note Chrysalis just sucked out Fluttershy's love.
