Luna dies
Bettina is questioned by Martin about his relations with Nick Terrier. She explains to him that Nick offered him the boat, saying that he had won the diamonds in poker. Bettina also admits having seduced Victor to recover the diamonds. Manon interrupts the interrogation, reproaching her for not telling the truth, convinced that she does not really want to help them. Bettina assures that the boat did nothing illegal: they only rented it to tourists. Suddenly, she thinks of something.
Manon calls William to tell him that the tourist boat had been used to hunt bats. She asks him if this could constitute a track to understand the contamination of patients. Roxane is convinced that they hold a start of the solution there and that they will find a remedy.
Samuel, Aaron and William look at illnesses that can emerge by contact with bats. They envisage a track, linked to the transmission by secretions. Samuel decides to take samples from the boat.
Chloé treats Luna and assures her that doctors will soon find a remedy. She asks him if she would accept to call Dorian so that he came to be treated in Saint-Clair. Luna refuses: she knows that by coming, Dorian would end up in prison, which he would not bear.
William joins Luna at her bedside and questions him about Bénédicte. The young woman tells him that they are now living on an island, with a garden and a dog. She claims to love Dorian passionately.
Victor crosses Bettina at the end of the police station and does not understand that it is released so easily. She explains to him that she wanted to recover her diamonds, that’s why she acted with him. Victor doubts that she really liked Nick, but Bettina tells her that it was sincere.
Nordine entrusts Manon that he made a promise: once this event is finished, he will ask her in engagement. Touched, Manon accepts.
An alert sounds in Luna’s room. The young woman makes a cardiac arrest. Doctors try to revive it, to no avail. Luna is dead. William says that if a remedy is not found quickly, all patients will die.
