As an AI developed by OpenAI, I don't have real-time updates or the ability to make predictions on future events. As of the time of my last training data in October 2021, the fifth season of "The Marvelous Mrs. Maisel" has not been released yet. So, I'm unable to provide information about what happened to Joel in Season 5.

However, I can provide an overview of Joel's character up until Season 4. Joel Maisel, played by actor Michael Zegen, is Midge Maisel's ex-husband. Throughout the series, we follow Joel as he navigates through his broken marriage, his struggling business and his complex relationship with Midge.

While initially portrayed as somewhat of a villain due to ending their marriage, the series also shows his considerable personal growth, ultimately redefining him more as a supporter of Midge's comedy career.

Though they separate, Joel and Midge share two children and continue to maintain a complicated relationship. They often lean on each other for support and sometimes struggle with lingering feelings. In Season 3, Joel starts a nightclub in Chinatown, transitioning away from his tedious job at Triangle Shirtwaist Factory. He also provides emotional support to Midge, especially after she gets fired from her world tour.

As of Season 4, there's a lot left open for Joel's character in terms of potential development and storylines. In terms of his professional life, we will likely get to see how his new nightclub fares. On a more personal level, it will be interesting to see how his relationship with Midge evolves, especially given their complicated history and shared experiences.

Joel's journey in the series mirrors the broader theme of the show itself: personal transformation amidst the demand for conformity, striving for career success while navigating personal challenges, and exploring new horizons in a rapidly changing society.

As for Season 5, fans and viewers will have to wait for its release. Given the depth and complexity of Joel's character, it's safe to assume that viewers can anticipate more twists and turns in his storyline which will continue to add to the charm of "The Marvelous Mrs. Maisel". We can predict that similar themes prevalent in the earlier seasons — like personal growth, career pursuits, and complicated romantic relationships — will continue to be explored. Upcoming seasons also offer an opportunity for the writers to expand on Joel's character and delve deeper into his aspirations, relationships, and experiences.

In summary, until the series makers release the fifth season, there would be a lot of speculation about what could be in store for Joel and the other characters. These speculations around possible storylines and character arcs, though inherently uncertain, do contribute to the growing anticipation for the new season of "The Marvelous Mrs. Maisel".
