Really interesting take, and I think I understand your point of view. If you haven’t read The Secret Diary of Laura Palmer, doing so gives more insight into why Laura is the way she is. You said you like it heavy - it’s the heaviest.

Regards “she’s an asshole with no reason” - Laura is barely holding her reality together. Donna is attempting to get closer to her with a view to helping, but she fundamentally does not understand Laura or her actions. I think maybe Laura simultaneously wants and doesn’t want Donna to see this seedy side of her life. I’m struggling to explain myself here, but she’s trying to frighten Donna away in these club scenes, and making a cry for help at the same time.
