It's one of the saddest weeks in ALDC history as Maddie and Mackenzie participate in their final competition with the team. The two sisters both have solos, but when Abby pits Mackenzie up against a new mini, Ari, it's clear that Abby is more concerned about her future than her past. The moms encourage Melissa to reason with Abby, since this is her last week, but she avoids the confrontation and takes her frustration out on the wrong person, ending her time with the ALDC like she never would have imagined.
