Tous-les-deux is the nickname residents of the Berghof give to a Mexican woman who has come to the sanatorium to be with her eldest son, who is gravely ill and eventually dies. Her other son comes to see visit his brother and falls ill and dies, too. Despondent and grieving, she dresses all in black and spends her days roaming the Berghof’s grounds. Tous-les-deux’s nickname comes from her inability to speak any German and hardly any French—unable to communicate with anyone, she greets every person she encounters with the exclamation “tous les deux!” (“both”), referencing her two dying sons.
