>>48564219The game doesn't support your headcanon. She does accept her loss after you achieve what she hasn't, and even cheers you on. It's clear she has insecurities about losing to a child after she's been spoiled all her life (being called "blessed" as a title) and clearly never lost before, but that doesn't mean she lacks talent, it just means you're a freak child prodigy who in the remakes catches a goddamn legendary bird right after you fight her.
If she's a leader due to reason other than skill it's because she's a part of the Dragon clan and Blackthorne leader is an inherited position, not because she's Lance's cousin.
She's really no worse than Blue, who people don't really complain about. In fact, she's better. At least after you prove you're amazing she backs down after very slight chiding. He just keeps going until Oak tells him he's an asshole to his Pokemon.
