Abby Lee Miller's students will be invested in more drama in the upcoming episode of "Dance Moms" season 6.

In the previous episode, chaos within the Abby Lee Dance Company erupted when Kendall's mother Jill Vertes made everyone know that she is not in favor of having Brynn Rumfallo join the team because it means that her mother Ashlee will be around as well.

But Abby assigned the 12-year-old Brynn as the leader of a trio to compete against lead student Maddie Ziegler's own group in the junior duet-trio division. Abby told her that if she managed to beat Maddie, she can have a permanent spot on the team.

However, the moms were not pleased when Brynn, Maddie's sister Mackenzie, and Kalani Hilliker won against the other team. Jill voiced out that she does not want to see Brynn in the group. This made Ashlee upset, since she felt that the mothers were discrediting her daughter's talents.

But the students got wind of the tension between their mothers, especially Brynn, who heard Jill and Kendall saying that her mother is an "awful person."

In the next episode, where the entire ALDC crew will be heading to Las Vegas to join the Sheer Talent Special Edition Competition, the altercation between Ashlee and the other moms will continue.

According to the synopsis for the upcoming episode, "The ALDC heads to Las Vegas; Ashlee and Brynn are now official members of the team; Kendall stands up to Ashlee for the first time; the mothers are concerned that the girls are becoming too involved in the drama."

Because of Kendall's row with Brynn's mother, all the other dance moms will realize that the kids are also affected by their arguments. Will they try to pacify the situation for the sake of their daughters?

"Dance Moms" season 6 episode 13 airs Tuesday, March 29, on Lifetime.
