hey Artie here's Winnie's summarized backstory as a lil treat

so for backstory to her backstory her family was among a group of humans living among the fairies and they were gifted fire powers by the fairies but then they rebelled and decided they hated fairies and have been training themselves to destroy the fairies again if they ever came back and uh Winnie's mom room it a tad too far

basically the fire powers had skipped her mother's (Riley's) generation for reasons and so Riley fucked the first man she could and conceived a child and basically isolated Winnie for the majority of her life, devoting her every waking moment to teaching her how to use her powers 

Riley allowed Winnie to transition after she attempted suicide and it was also a sort of manipulation tactic she held over Winnie's head throughout her entire life because whenever she'd express any minor grievance Riley would say "well I let you become a girl, so be grateful" and just all around Riley was very abusive and manipulative and only saw Winnie as a weapon

onto Prestige Queen and Lady Fairy: A Tale Of Two Queens where Winnie gets introduced and she tries to kill Flower and Rosette and Gaia and Carlotta and as the movie goes on it showcases her progressively getting more and more desperate as she's unable to kill the fairies and she's beyond terrified of what her mother will do to her if she's unable to kill them

they end up helping her get away from her mother and also for the beginning of the Hush movie Winnie and Rosette do not like each other. well, Rosette doesn't like her, Winnie spends it all profusely apologizing but by like forty minutes in they're girlypops

Winnie currently is just trying to find redemption in herself, see herself as more than a fairy killer, see herself as more than her mother's little weapon and try and hate herself left because yeah this bitch got a lot of self loathing going on 

she's moving around from place to place though generally stays at least nearby the other Powerstrike girlies and she spends a lot of time at Ellie's
