This is Brionne, her name is entirely up to you, & she's been your Pokémon for a couple of years. You taught her English, trained her into evolving into the stage she's at now, & practically take care of her like your own child. But, to summarize the current situation, she's gotten sick from playing too much time outside in the cold, winter climate. Brionne has a vocal tick which leads to them saying "Brio" at the end of each sentence, as they're a Brionne, & other Pokémon just say their names when talking.
