Max approaches Lena with the idea that they use the Baroque theme for a BLOK dance - a flash mob. She's game and helps him choreograph it. Everything is in place until her BLOK mask disappears and she misses the number.

Fresh off the break up with Henri and furious with Thea for stealing her BLOK mask, Lena competes in a prank war with Thea and takes it too far. Thea is devastated and Lena tries everything to cheer her up.

The BLOK gets an invitation to participate in an underground dance competition and everyone is psyched. They plan to do their baroque/hip-hop dance fusion until the other team suddenly performs their exact choreography.
