Welcome To Plathville's Olivia Plath has been accused of many things by the Plath family in the past, most recently of maliciously deleting music Moriah Plath had released and keeping the proceeds. While Olivia has been a polarizing figure for the Plath family throughout her time with their son, Ethan Plath, things have come to a head in recent years and throughout the start of Welcome To Plathville season 5. Moriah, who used to be incredibly close with Olivia, was depending on her sister-in-law for help with her music career, especially after the release of her song "Missed Myself". While Olivia helped with the music, the release was somewhat tricky.
