In ET's exclusive sneak peak of Thursday's episode of Braxton Family Values, sisters Toni, Tamar, Towanda, Trina and Traci Braxton invite their father out to dinner, but things get heated when talk turns to their upcoming family trip.
"I think we need a family trip," Toni says of heading to Mexico. "I think that's the problem. We need to all get together and bathe in the sun and eat and drink and giggle... That's going to unite us again."
In the name of family unity, the sisters even want their divorced parents, Evelyn and Michael Conrad Braxton Sr., to come along for the getaway.
The plan quickly turns tense, however, when Michael Sr. reveals that he wants a special guest to join him in Mexico. The family patriarch suggests that his second wife go on the trip for a potential face-to-face with Evelyn.
The backstory between the two ladies -- Michael Sr. cheated on Evelyn with the woman that he later married -- would make for a potentially awkward group getaway, and the sisters are clearly not happy with the idea.
"That sounds like a disaster," Tamar predicts, before explaining that, if she were her mother, she would punch her father's wife in the face "on sight... just because."
It's obviously going to take more convincing for the sisters to get on board with their father's idea of a family trip. See the drama unfold in the clip above!
Braxton Family Values airs at 9 p.m. ET/PT on WE tv.
