“The family is falling apart,” Ethan says. “And it’s a big old mess.”

Micah, 22, struggles to accept his parents’ separation while he’s on his own out in California. He admits that he’s “still bitter about the whole divorce.”

“I always thought you and dad were, like, perfect together,” he confides to his mom. He later says he doesn’t want to “keep walking around eggshells around every single person” in the midst of all the family drama.

Oliviais shown reconnecting with her sister Lydia Grace, whom she hasn’t had a relationship with since the pair were teenagers. “My parents thought Lydia was walking the fine line to hell,” she explains. “So I cut ties with her.”

In the meantime, Kim is embracing the dating life after hersplitwith Barry. A friend teases that she’s “keeping secrets.” Next, she’s seen on a date with a new man — who has yet to be revealed — and asking, “Would you call me your girlfriend?”

Moriahis shown with a giant tattoo across her arm that reads “REBEL.”

“So you’re rebelling against everything that our enemy has planned against you?” Barry questions his daughter.

“That sums it up!” Moriah replies.

Later,Ethanis seen entering an empty home. “I get back, she’s gone,” he says as he finds what appears to be a letter. “I’m just so tired of all the nonsense.” It’s unclear if he’s referring to Olivia — or Moriah.

Moriah is seen having another conversation with Barry. “This is gonna come as a shock, but…” she starts dramatically. The trailer then cuts to Moriah speaking with Ethan on the phone, clearly upset. He questions “what the hell” his sister is talking about.

“Just don’t forget that I love you,” Moriah is heard saying. “I don’t know when we’ll speak next.”

We see a montage of various family members getting emotional, then what appears to be Moriah getting baptized. “I’ve carried all this baggage and weight of all the mistakes that I’ve made my whole life and it’s time to just put that down,” she narrates as Barry places her into a body of water.

At the very end of the trailer, Ethan can be made out dramatically crying, “Olivia!”
