So, Bojack would end up dying in prison for some reason (maybe he kills himself or something), his relatives, friends and ex friends (even the “fuck” friends - except Herb, because he’s already dead) cry for him. Some years later, Hollyhock(the one who suffered the most with Bojack’s death) gets married and has a baby(wich is implied to be a reborn Bojack) , who she calls Bojack as a homage to her dead brother, swearing she’ll not let him go through the same way Bojack went.
