S1, E6: Alison discovers she is pregnant and confides in Berthe, the peasant, making her promise to keep it a secret. Of course, Berthe can't keep her mouth shut and tells the other ghosts. Very excited about the news, they start looking for a name for the baby. But for Alison and Nabil, this pregnancy is not compatible with living in a dilapidated castle. They decide to sell and find a more suitable place to raise a child. The ghosts, who have grown attached to them, are desperate and try to convince them not to leave. Except for Georges, the military man, who is busy looking for a new group to command.
