Thea is a rather important character in the region and while going into detail about her would enter spoiler territory, it’s safe to say that you’ll encounter her quite a bit during the course of the story. She’s been sheltered from the outside world for most of her life, so she’s a bit awkward and tends to be overly serious when the situation really doesn’t call for it; but she has a good heart and wants to not only help people and pokemon, but to also prove to her overbearing father that she can take care of herself.
