...the stereotypical answer would be that she'd be a fervent Edward/Bella shipper. But this is selling Cori short. She did have a strong moral compass, though it was a completely bonkers one, and she had a pathological hatred for inconsiderate, arrogant, and/or self-centered people. That she ended up making Team Rocket precisely that was... probably a sign that something had gone haywire upstairs. But when she wasn't going batshit insane over her hatred for Ash, she was fairly consistent.
Where am I going with this? I'm pointing out that Cori was a militant friendshipper - oh, and while I'm at it, she had an utter infatuation with mystic spiritual powers and the idea of soulmates.
That's right. She'd be a Bella/
Jacob BNF.
And she'd probably be a Big Name Anti-Fan, though she'd rapidly creep the other snarkers out. I somehow think Cori's WRH of New Moon would end with a live Edward delivered back to the Cullens in several pieces (since vampires can survive disembowelment, remember?). And she would throw the most EPIC shitfit come Breaking Dawn. It would make New Beginnings look moderate. And the sad thing is that she'd have halfway-decent justifications, since all vampires in Twilight canon either murder humans or tolerate murder as an alternative dietary choice... but then she'd hurl the werewolves right past several Moral Event Horizons and not even realize she was doing it. And then there would be some ritual to make Bella a werewolf, and ahaha I am so tempted to write a trollfic in this style as a tribute to Miss Falls. ...I am SO tempted.
