Most people don't know this, but Fluttershy isn't vegetarian. She spends so much time around carnivores and sick and dying animals that she is quite familiar with and accepting of the fragile temporary nature of life and how every second you spend, be it eating weasels or planting crops or refilling water bottles, or reading this crappy story is one more second you stand closer to the swift approaching unavoidable and all-encompassing eternal void of death. Fuck, that's depressing. Anyway, inasmuch she has no ethical objections to eating meat, and also, it's really delicious I mean seriously have ever had Orange Chicken?
Fluttershy inasmuch was pescetarian--that is, she only ate fish. Not like as in, "and nothing else", but rather, fish were the only formerly sentient creatures she ate.
Anyway, weasels are sort of like fish in that they are slippery and will slip right out of the web of lies they've created, and Fluttershy couldn't catch fish in the stream near her cottage because the Flemish had poisoned all the streams in and around Ponyville. Jesus fuck, never trust a french-speaking Belgian, at least not in Equestria.
Fluttershy was hungry and weasels are sort of like fish, so Fluttershy ate one. To kill it, she used the stare on it then boiled it alive while it was paralyzed by her dreadful peepers like fuck I'm saying fuck a lot but what a fucking way to go!
After it was nice and tender, Fluttershy ate it until only about a third of the lower body and entrails were left, which she fed to Harry the Bear.
