FierceIris
Dragon Master
Yeah, she loves using pkmn whose strength and ability to synchronize with her fighting style are unproven, so if she did catch him/it, she'd surely try to impress Shaga and use it.
She hasn't done anything like that before, so why should she do it now? It's more a case of her taking every chance she gets to try and bond with her Pokémon, like she did with Dragonite during the Juniour Cup. I doubt she felt proud over showing its disobediance, rather the opposite.
