BoJack promises his publisher to write a better book than Diane, but finds himself struggling to start. He, Todd, and Sarah Lynn take drugs together and write a gibberish book, and Todd admits he does not care about the loss of his rock opera because he did not expect anything better from BoJack. BoJack begins to hallucinate visions of Diane and Horsin' Around while trying to reach a conclusion about his self-worth, and he has a flashback to his mother forcing on him the same advice he did Sarah Lynn. He imagines marrying Charlotte, a deer that was close friends with him and Herb, and having a daughter with her, only to finally wake up from his hallucinations. He goes to Diane at a ghostwriter convention and admits her book is excellent. He begs her to tell him that he is a good person; Diane does not respond.
