To be honest, I have always rooted for RA because he is trying to better himself, a loving father to Blue, and I want him to win, but he frustrates me because he constantly sabotages himself, and leaves everyone to clean his mess. I had a feeling spilling the beans about the land would not go well with the sisters. I get that he wanted confess, but if he had any sense he should have either told them from the beginning or listened to Aunt Vi, and kept his mouth shut (then again, it would have came to light somehow--he and Charley would have one of their spats and he'll blurt it out). Since Charley, practically financing the land, it was wrong from him to keep this a secret. Now this has caused a serious rift in the family, as RA as finally burned his bridges with both Charley AND Nova--and maybe Aunt Vi, since she warned him....and now Darla has put herself in a predicament as she his working for his sister. Aside from Blue, she should just separate herself from the Bordelon family, and start her own life. She's doesn't need the stress.
That said, it's sad that their father worked himself to the grave, to provide for the family while RA kept getting himself locked up.
