Ethan Plath wasn't sure of sister Lydia Plath's whirlwind romance during the Welcome to Plathville season 7 premiere - especially after his own marriage ended in divorce. The Tuesday, July 22, premiere focused on new beginnings for the Plath family. Ethan, 27, and sister Moriah Plath were newly single when the cameras picked back up in fall 2024, while Lydia, 21, and Issac Plath were happy in fresh relationships. Micah Plath, meanwhile, revealed he had "tension" with girlfriend Veronica Peters after she and Moriah, 22, experienced a falling out between seasons.
