Things are about to get seriously dark on “Dance Moms.” Abby Lee Miller will assign her students murder-themed solos and an equally creepy group routine on Tuesday’s Season 6 installment of the Lifetime series.

After teasing that Brynn Rumfallo may not get a solo in episode 10, the synopsis for “Abby Lee Horror Story” reveals Abby will definitely be gifting the newcomer her own routine. Fellow elite junior team members Maddie Ziegler and Kendall Vertes will also be gifted solos. However, it may not be what they were hoping for.

“The ALDC travels to Northern California where the perform dark routines,” the summary reveals. As previously reported, the girls will be portraying infamous murderers and victims.

Unfortunately for Brynn, it doesn’t appear her week at the ALDC will be without drama. The promo video for episode 10 reveals that her mom, Ashlee, will get involved in a verbal spat with Kendall’s mom, Jill Vertes. “You sabotaged six other kids to make sure yours got what she needed,” Jill tells Ashlee.

“You are pure evil. You guys can all go to hell!” Ashlee responds before storming out of the studio. Could this be the end for Ashlee and Brynn?

Elsewhere in episode 10, the moms will “attempt to play a prank” that backfires. While the synopsis doesn’t reveal who the prank will be on, Abby appears upset in the promo. “Today these moms made a decision,” Abby tells the cameras. “That decision was detrimental.”

[Spoiler Alert]

While Abby has been hard on Maddie since she returned from filming the movie “The Book of Henry,” she managed to get a first-place for her coach at NYDE in San Jose, California, Dec. 19. One “Dance Moms” spoiler site reports Maddie placed first in the 13-14 age division with her character solo “Lizzie Borden.” Kendall placed second in the same age category for her lyrical routine “Natalie Wood.” Brynn, who competed in the 11-12 age range, took home second-place for her contemporary number “Black Dahlia.”

The ALDC’s contemporary routine, “The Cult,” placed first overall in the 13-14 division.

“Dance Moms” Season 6, episode 10, “Abby Lee Horror Story,” airs Tuesday, March 8, at 9 p.m. EST on Lifetime.
