When Adrien gets nervous about meeting his grandparents, Marinette gatecrashes the lunch to support him... unaware that a family war is about to break out. Due to shenanigans involving Marinette and Plagg, the meeting escalates rapidly, culminating in Lady Milly being akumatized into "Ringmaster," who turns Emil and Johnny into the "Werepapas" and forces them to fight for Adrien's custody. Ladybug single-handedly defeats them, and Marinette suggests that Adrien should live his own life in Paris with Nathalie, whom he already treats as his mother.
