Ethan Plath hit his breaking point with Micah Plath's girlfriend, Veronica Peters, during the latest episode of Welcome to Plathville - and he wasn't alone. "Well, Veronica's here with Micah, unfortunately," Ethan, 27, told his girlfriend, Teegan Nichols, during the Tuesday, September 9, episode of the TLC series, after Veronica arrived at his sister Lydia Plath's wedding rehearsal. Ethan quipped, "She's become quite a little demon," describing Micah's long-term partner. "I'm just going to kill her with kindness," Teegan responded, trying to calm down a frustrated Ethan.
