The ALDC's revolving door continues as Abby auditions a new dancer to be a part of the "Great 8" team heading to Nationals. Brynn, Lilly, and Maesi all go head-to-head with solos. And, the moms are hopeful the new dancer will complete the team, but Ashlee thinks otherwise when her mom insults Brynn.

The ALDC travels to Denver where both the stakes and the altitude are high! For the first time this season Kalani, Kendall and Nia all dance competing solos. Much to the elite's dismay, the minis are in a technically complicated group dance, and the moms once again wonder if this addition will ruin their winning streak heading into Nationals.
