Memo finds a stray puppy outside the building and sneaks it inside, giving it to his friend Manu. Meanwhile, Agnes informs the others about the dog, but they initially dismiss her, as she is known for making things up. However, after her persistence, they reluctantly check the room and are shocked to find Manu holding the puppy. Manu fabricates a story, claiming he adopted the dog because it had nowhere else to go, and apologizes for not informing them. Cecile is touched by his selflessness and allows the dog to stay, though Agnes and Serge have their reservations.
