>>28332263She has a huge social insecurity about herself, she doesn't have Lance's greater part of his attention, and is constantly believing herself to be second to Lance because apparently she doesn't also have the approval of the elderly peanut gallery despite her position as Blackthorn Gym Leader and probably the strongest Dragon trainer in town (perhaps short of the elders), probably got wind of news about how this random kid teamed up with her childhood friend to take down Team Rocket while she was stuck at home, WAS probably undefeated (despite the ice cave that aspirants need to conquer to get to her Gym) until player showed up and showed her
that Dragon or no, weaknesses or no, status moves will still fuck you.
