Complete story — includes the ending
In the second season of Philbert, a series of strangulations start to occur. BoJack begins to hallucinate the runaway Philbert balloon and brief flashes of his everyday life being on a dark TV set, as well as a golden set of stairs leading up to a bright destination. When he receives a letter under his door that promises to expose his deeds (actually a Philbert advertisement), he begins to conflate his real life with Philbert's and investigates everyone close to him, including Diane, Princess Carolyn, and Charlotte Carson. He has a bizarre musical dream performed by Gina that questions the true motivation of his addiction to fame. Gina finds his stashes of painkillers and leaves him when he tries to take them back by force, while on the show, her character discovers Philbert is actually the one responsible for the stranglings. He starts to choke her, and BoJack does not stop when Flip ends the take, forcing Mr. Peanutbutter to pull him off as everyone watches in horror. BoJack flashes out of reality to the stairs and ascends them, finding himself in a crudely drawn empty space with the Philbert balloon floating above him.
