Rewatching the show. Heather is not in season 1, but is a background in the dance class (episode 14). If they are so close and been so close since HS, why don’t they talk as friends during class? Also, Donna is there in the Hawaiian birthday, and in the “no bs” video she had made. Was she originally a “friend” ?
And, she is really pissy with people. Really rude and SO loud. How did I not really see that first time I saw this show….
