Welcome To Plathville season 5 just began, but things are already looking rocky for Ethan Plath and his wife, Olivia Plath, who may or may not still be together. As the Plath family unravels due to Kim Plath's split from Barry Plath, things are getting more difficult for Ethan and Olivia's marriage. Though Ethan and Olivia have a strained relationship with his family, in the past they have done their best to continue to foster their connection. Olivia, who had a tough falling out with Moriah Plath between the last season of Welcome To Plathville and the current one, is far more on the outs than Ethan is.
