Worried to see Sarah hovering around Thomas, Léa goes to Sainte-Marie to mark her territory; she's disappointed to see that Thomas doesn't come to pick her up, busy doing a "job" with Seb and JP.

To heal from her heartbreak, Léa decides to accept Éloi's invitation and attends a costume party; her presence doesn't sit well with the simpletons, especially Marianne, who tries to get closer to Éloi, but Alex only has eyes for her.
