BoJack tries to explain how the audience isn't supposed to like Philbert as a character or agree with anything he does, and realizes that what the show is doing is normalizing Philbert's behavior.
BoJack leaves and goes to Diane's. He asks her to come work with Flip on the show, to make it something that they can all be proud of. BoJack tells her that this is her chance to change society for the better. Diane says that nothing she does causes any real change to happen, but BoJack says that she changed him.
