With Nationals just five weeks away, the flu wipes out half the team. Glo makes a last-minute decision that sparks outrage, especially from Kaeli and the moms. Two soloists go head-to-head in comedic routines, but for one of them.

Kaeli asks Audrey to redeem herself in a new ballet routine after last season's disaster, but Tammi isn't up for the challenge. As Nationals loom, Glo dares Ashlan to go a week without Lisa's help and Corinne tries not to spew her anxiety onto Lily.

With Nationals approaching, Glo asks the Dance Dads to be more involved than ever. Bellatrix's solo forces her to open up, Smiley performs a tribute to a pop culture icon, and Miah struggles to nail the lead of a murder mystery group dance.
