Welcome To Plathville season 5 has explored Ethan Plath’s relationship with his wife, Olivia Plath, but tends to show his relationship troubles as Olivia’s fault rather than his own. Ethan and Olivia’s relationship has been rocky in recent years, especially after Ethan’s family has chosen to ostracize Olivia for their perception of her actions. In the past, Olivia has been close to Ethan’s family, though things weren’t easy in her relationship with her mother-in-law, Kim Plath, or her father-in-law, Barry Plath. In recent years, Olivia’s had a better relationship with her sister-in-law, Moriah Plath, but things changed after the two had a falling out before Welcome To Plathville season 5.
