11. Sunk Cost and All That

Complete story — includes the ending

Mr. Peanutbutter, Pickles, and Joey open the new restaurant and attempt to run it together, with Pickles and Joey disliking each other despite Mr. Peanutbutter attempting to get them to sleep together. They do, and discover they have feelings for each other as Pickles leaves with Joey for his upcoming tour. Sinclair and Banks ask Mr. Peanutbutter about seeing BoJack at his house during his bender with Sarah Lynn, which he confirms, as well as unintentionally revealing that he and Sarah Lynn had heroin with them. BoJack, Diane, Princess Carolyn, and Todd hole up in his office to determine what the story being run on him is, which they discover is Sarah Lynn when Sinclair calls Diane. BoJack expresses anger at being grilled after he has changed for the better, causing Todd to leave after seeing the "old Bojack" return, and while Princess Carolyn plans to help him beat the story, Diane insists he should be honest and leaves in disgust when he lies to Sinclair on the phone. He asks Princess Carolyn why she is helping him after everything, and she says it is because she has loved him longer than she has loved anyone else.
