New details for Sex Education season 4's story are revealed. Premiering in 2019, Netflix's coming-of-age series quickly became an instant hit for the streamer. Sex Education follows the lives of students and staff at Moordale Secondary School, primarily Otis (Asa Butterfield), a socially awkward student who starts an underground therapy business along with his friends, Maeve (Emma Mackey) and Eric (Ncuti Gatwa).

Three seasons later, Netflix is gearing up for Sex Education season 4, which will look significantly different from its predecessors because of a much smaller cast. In the last several weeks, several actors from the show have confirmed that they won't be returning for its next installment. Bridgerton's Simone Ashley won't be back as Olivia, and neither will Patricia Allison as Ola or Tanya Reynolds as Lily. Most recently, Rakhee Thakkar, who plays Moordale's English teacher, Emily Sands, announced that she also won't be involved. This has been a cause for concern for fans, who are wondering what Sex Education season 4's story might be without them.

Now, new details emerge regarding Sex Education season 4's story. A source tells Variety that the show will “see a mixture of old and new exciting faces” when it returns for its next outing. It also adds that the show will focus on the remaining characters finding alternate schooling arrangements after Moordale's sale to developers. Read the related excerpt from Variety's report below:

Despite the mini exodus, a source tells Variety season 4 of the show will “see a mixture of old and new exciting faces” as the Moordale Secondary School alumni seek an alternative place to study – and romp – after the school lost its funding and was sold to developers.

Amid the string of departures, one piece of good news is that Gatwa is confirmed to return as Eric in Sex Education season 4. After the actor was cast as the new Doctor Who, there have been doubts about his involvement in the Netflix series, since most of his time will be devoted to filming the iconic BBC show. While details about how prominent he will be in the show are still unknown, the fact that he's returning is a huge win, since Eric is one of the best characters in the project. In light of this, it's safe to say that both Butterfield and Mackey will be reprising their roles as Otis and Maeve in Sex Education season 4 as well.

The story details for Sex Education season 4 support theories that its narrative may take place exclusively during the school break as the remaining cast scramble to find ways to continue their schooling. While not seeing some of the familiar faces back is disappointing, a much smaller cast allows Netflix to focus on certain plotlines that haven't been fully explored, which includes Otis and Maeve's relationship. Given their season 3 ending, it's time that Sex Education season 4 finally provides some kind of satisfying payoff to their long-gestating romance.
