[x] The Balls. She's smart enough to have brought a backup Pokeball in case you fry the first one, but little does she know that you have two paws! Steal both so she can't throw them when you're distracted.
[x] The Badge. You put a lot of hard work and effort into utterly humiliating Rojo and robbing him of his precious badge and possibly also making him cry. How dare she try to undo your efforts?
[X] The Bunny. Come on. It's a big dumb slow goofy Water type. Like an egg with ears. It'll go down in a single zap, and then she'll have lost the badge and you'll have a perfect hostage!
[x] Benevolence. Nope nope nope, absolutely not, you're not having any of this "mercy" or "tolerance" nonsense; she is insulting your glorious victory and has chosen her doom.
