But in a preview of the season shared exclusively with PEOPLE, Tammy’s return is met with chaos: Not only is her husbandCaleb Willinghamhaving trouble maintaining his weight loss back at the rehab facility, but her sisterAmy’s marriage to her husband of 6 years,Michael Halterman, is imploding.

Tammy’s homecoming begins on an upbeat note, with her proudly sharing “I lost 300 lbs. And I’m ready to conquer the world’ — even though she says she can’t imagine leaving without Willingham, who hasn’t been approved for discharge yet at Windsor Lane Rehabilitation Center in Gibsonburg, Ohio, where they met andlater married.

At first, her return is met with laughter and levity. When Tammy and Amy, 36, struggle to open a jar of pickles, Tammy cracks, “You got two children, I thought you knew how to handle a pickle.”

In reply, Amy shoots back, “I’m used to the bigger pickles,” causing both sisters to laugh.

“She’s been around a lot of pickles,” Tammy later explains, again prompting the reunited sisters to crack up laughing.

And this season, weight loss is fully a family affair, as half-siblings Amanda and Misty share that they’re seeking approval for weight-loss surgery, whichTammy had in 2022andAmy had in 2020.

“Do we get a family discount?” Amy quips to the camera.

But while Amy is quick with a joke, the preview shows that she’s deeply struggling to manage the household and her two young children,Gage Dean, 3,andGlenn Allen, 1.

“I am very overwhelmed, stressed-out, and Michael ain’t doing s—,” she says. “Every aspect of my life is chaotic because I have no support.”

Amy’s marriagecontinues to decline, as she tearfully tells her family, “I’m exhausted all the time, because I’m trying to take care of two boys and take care of the house.”

“I feel like I’m at my breaking point,” Amy later says.

But things explode during a confrontation in their living room, when Amanda confronts Michael, angrily demanding that he give Amy her debit card or she’s calling the police.

“I ain’t giving her s—,” he retorts, walking away, prompting Amy to to chime in, “No, he’s got two seconds to get his s— and get out of my house.”

While sister Misty tries to break things up, Tammy calls for help. “I’m calling the police. I’m not f—playing,” she says.
