"The seasons begins with a newly-motivated Abby Lee promising to no longer overlook her remaining dancers now that her star, Maddie, is gone. Abby assigns Brynn and Kendall head-to-head duets with boy partners and Brynn struggles with the pressure. When Jess calls out Abby's favoritism for Brynn, Ashlee hits her boiling point," the synopsis read.

According to the show's official spoiler site, Brynn also suffered from a minor injury during her performance. This caused her to run off stage. While there, she was checked by Miller and her mom Ashlee.

Meanwhile, next Tuesday's episode of "Dance Moms" season 6 is entitled "Nia & Kendall Face Off." The two members of ALDC's competition team will be pitted against each other in episode 20.

"Abby challenges Nia and Kendall with tough head-to-head trios but the group tribute to Madonna leaves the moms wanting more. Holly suspects Abby has a hidden agenda for Nia, but when she brings Nia's manager to the studio to investigate, her strategy backfires. When talk of the girls' technique erupts at competition, Abby abandons the team," the synopsis read.

In other news, episodes 21 and 22 will be called "Return of the Minis" and "Mother's Day Meltdown," respectively.

Episode 21 will see the arrival of Alexus Oladi, Areana Lopez, Elliana Walmsley, Peyton Evans and newcomer Lilliana Ketchman. "The minis are back for the first time this season and the elites question if Abby can hold true to her promise of new beginnings."

Episode 22's synopsis reads: "It's Mother's Day and an emotional Abby tasks the minis with their first lyrical routine to honor their mothers. The elites are put to the test when their moms make a shocking decision that leaves them without a group dance for competition."

"Dance Moms" season 6 airs Tuesdays at 9 p.m. ET on Lifetime.
