When Sabrina Enters the Top Boy Competition
When chapter two begins, Sabrina is attending the Academy of Unseen Arts full-time. She wastes zero time becoming a feminist icon by entering the school's Top Boy competition, a series of Goblet of Fire-style challenges meant to decide who will best represent and serve as an example for other students. Of course Father Blackwood throws a misogynistic stink about it, and even Ambrose's boyfriend, Luke, tells her, "It's Top Boy for a reason, Sabrina."*
Even though Sabrina doesn't officially get the top boy role (it ends up going to Ambrose), she still ends up saving the Academy from witch hunters and saving the coven from Father Blackwood's horribly sexist doctrine.
*Luke turns up dead a few episodes later. I'm not saying his shady comment had anything to do with it, but. . . may he rest in peace, I guess!
