Clearly their relationship deteriorated once BJ started his lecturing gig and Hollyhock found out about New Mexico (nail in the coffin being the televised interviews). However I can’t help that feel that Hollyhock has some of the same character flaws as BJ, and despite his major issues , he’s still family. In that sense maybe BJ would get her in a way others wouldn’t. I kind of hope that in the long run BJ gets his shit together and they can form a healthy relationship.
She doesn’t need him. As someone who’s estranged from family and as happy as I can be with it, I can honestly say that I think she won’t see a point in reconnecting with him. Her mom can cover any unanswered questions from this point. She has all the evidence she needs to show her that her brother isn’t someone she wants in her life or someone who will benefit her.
So, no.
