Complete story — includes the ending
BoJack awakens in a recurring dream of his, where he goes to a dinner party at Beatrice's house and eats with other dead people, including Herb, Sarah Lynn, Crackerjack Sugarman, and Butterscotch Horseman in Secretariat's body. They discuss the best and worst parts of their life before going into a theatre, at which point BoJack claims his dream usually ends, but it continues. As the attendees all perform acts that relate to their lives before being sucked into a black doorway, Butterscotch pulls him aside for a smoke and expresses his regrets about their relationship, before revealing BoJack is, in reality, drowning in his old pool. As the rest of the attendees vanish into the doorway, black tar emerges from it and starts to chase BoJack through the house. Remembering that he called Diane before the dream started, he assumes that he cannot be dying, and so he tries to call her again. She points out that nothing that is happening is real and she never picked up the phone, and so he accepts his fate of the black tar engulfing him as he asks how her day was.
