Kim Plath is willing to talk about her late son, Joshua, but chatting about him with son-in-law Zac Wyse is anything but fun.
“I’m aware that Zac likes to have really deep conversations, but I don’t know that ‘excited’ is the word I would pick,” Kim, 53, tells the cameras in Us Weekly’s exclusive sneak peek at the Welcome to Plathville season 8 finale, airing Tuesday, June 16.
Despite being uncomfortable, Kim sits down with Zac, 24, who tries to explain how “excited” his wife, Lydia Plath, is to “just be able to share this with her family who experienced it with her.”
Zac reveals it’s “awesome” and “great” that Kim is willing to talk to not only Lydia, 22, but everyone else about Joshua, after Lydia claimed her parents never spoke about him once he died. (Joshua died in 2008 when he was 17 months old following an accident on the family farm in which Kim was driving and ran him over.)

“I’ve given up trying to fix things and make every relationship work and every relationship perfect,” Lydia tells the cameras, noting that only “time” will tell whether Kim and Zac “choose to spend time together and grow or not.”
Zac, for his part, says in a confessional that he doesn’t “understand” Kim and how she “operates.”
“I’m trying to understand a lot of the decisions she’s making, but it just doesn’t click for me,” he admits, seemingly referring to Kim’s choice not to relive her heartbreak with Joshua publicly like Lydia did during a January podcast. (Lydia’s brother Ethan Plath, meanwhile, revealed during a June episode that he doesn’t like to talk about Joshua “publicly unless it’s remembering him for who he was when he was alive,” saying it was “disrespectful” to speak about his actual death.)
Zac and Kim stumble through their conversation, with Zac telling his mother-in-law, “Grief is definitely more complicated, I feel like, at times.”
Kim explains during the heart-to-heart that she will “always be a parent that lost a child.”
She notes, “There’s no amount of thinking, talking, writing, what, praying, anything that could change that.”
Kim reveals that she feels like she “lost so much” of her life during the year after Joshua’s death that she doesn’t like to go back there.

“You don’t want to be in that place again,” Zac says, to which Kim replies, “Yeah.”
Kim, however, notes that if her other nine children, whom she shares with ex-husband Barry Plath, do “need me to go back there for a while, I’ll do it.”
Zac is happy to hear that, responding, “That’s good,” since his wife has been asking Kim to talk about Joshua more and more.
“Lydia over the last few years just worked really hard to really just be seen in the family. And I don’t feel like Kim really try to see her or tried to even see [her],” Zac tells the cameras, getting choked up. “I don’t want to talk about this because I don’t. I can defend my wife, but in all honesty, I don’t know what they’ve been through. Period.”
Kim, meanwhile, says in her confessional that she understands where Zac is “coming from and he means well,” but she’s still unsure what he “needs from me in order to feel accepted [and] loved.”
