The ongoing drama between Emily and Kamani reaches a boiling point in this sneak peek from the season finale of "Inside Only Cabo," airing tonight at 9pm ET.

The series features celebrity hair stylist Larry Sims who takes six of his closest friends on a “once in a lifetime trip” to Cabo San Lucas, Mexico. These friends are from different phases of his life and many of them barely know each other as the vacation begins - but it's not long before they're tangled in conflicts, jealousy and even a few steamy hookups.

The crew includes makeup artist Kamani Alana, single mom Bianca Banks, Sim’s oldest friend Jermane Britton, the “unpredictable” Australian Emily Moses, the flirt Agu Ukaogo and the show’s “voice of reason” Malaku Quisada.

Tension has been simmering between Kamani and Emily for a while, but things came to a head in the previous episode when Emily ranted about Kamani in the car on the way to dinner and said some not-so-nice things about her daughter — things that she was too drunk to remember saying the next day.

Kamani seems to have had enough when she confronts Emily in the kitchen the next day.

"What you don’t do is you don’t f--k with my family, like you just did the f--king motherf--king most," she said. "It’s not okay."

Emily retorts that Kamani refuses to talk to her and "then you talk s--t about me behind my back constantly."

The argument makes things awkward for the rest of the crew, who are listening in from the next room. "Get over it," Malaku says. "They’re arguing about nothing, really."

Back in the kitchen, Emily insists that she shouldn’t be blamed for what she said in the car because she can’t remember it. "I don’t really recollect those things, so it’s just making me feel more attacked, because I wasn’t actually present."

"I’m not going to let you play the victim," Kamani fires back. "There are just certain lines you don’t cross... No matter how you feel about me or how I feel about you, one thing I’ll never do is if you had a daughter or [family member], I would never come for your family."

She continued, "That’s why you and I have not talked - because there’s nothing to talk about any more. When you go for somebody’s family, we’re done, I can’t. Because I don’t want to go there with you."

"Invite Only Cabo," airs Sundays at 9pm ET on Bravo.
