Jestro hatches a plan to ambush the Fortrex in an attempt to cheer up the Cloud of Monstrox, unaware that the knights are currently at a party. Fortunately, Ava manages to restore Merlok 2.0 to the Fortrex, and he provides the Knighton Academy students with a Nexo power that enables them to fight back against the Stone Monster Army. Forced to retreat—as they lack the Cloud of Monstrox to reanimate them—the army’s withdrawal amuses the Cloud of Monstrox. Back at the party, Macy loses control of Clay’s battle suit, compelling the Nexo Knights to pin it down. After the celebration, they disclose the truth about Clay to King and Queen Halbert, who agree not to speak of it to the rest of the kingdom.
