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 was right to cut bojack from her life. She said she could use a brother, but it seems all bojack has done is been a burden and danger to her. Im glad she had the maturity to realise that and she already has a strong support network to help her grow as a person beyond needing the company of bojack to overcome her struggles
