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.
No. Bojack won’t get closure here, and that’s one of the major thesis statements of the show. Bojack doesn’t get closure with Herb, or Penny, or Sarah Lynn, or his mother, or a dozen other characters, he doesn’t get closure with Hollyhock.
And unless extreme circumstances bring them back together, I don’t see any reason for Hollyhock to change her mind.
