In late November, Vianne wakes from another dream of Antoine and faces worsening shortages and cold. Isabelle slips in from an early outing, and Vianne suspects Isabelle is sneaking out for someone. At breakfast, Captain Beck gives Sophie a chocolate bar and leaves, while Vianne’s guilt over the “list” she provided still gnaws at her.

At school, German and French authorities arrive with a list and dismiss certain teachers, including Jews and others deemed unacceptable; Rachel is among those forced out. Vianne keeps teaching in a daze, haunted by Rachel’s look, then leaves at midday to confront Beck at the Kommandantur. Beck insists he did not order the firings and warns Vianne it is dangerous for her to be seen there, but Vianne realizes her visit will be noticed.

Outside, townspeople see Vianne leaving the German headquarters, and Isabelle angrily challenges her. Vianne admits she gave Beck the list of names, including Rachel’s, and Isabelle tells her that Rachel—not Isabelle—is owed an apology. Shaken, Vianne goes to St. Jeanne’s chapel and confesses her mistake to Mother Superior Marie-Therese, who warns that everyone will be tested, that righteousness may be dangerous, and that Vianne must decide what sacrifices she can live with.

Determined to take responsibility, Vianne visits Rachel and admits she gave Beck Rachel’s name. Rachel reacts with hurt and anger but ultimately accepts that everyone already knew she was Jewish and urges Vianne to be more careful, reminding her that Beck is still a Nazi and therefore dangerous.

As winter deepens, the narrative shifts to Isabelle, who continues distributing anti-Nazi tracts despite little visible effect. She sees posters announcing executions and a new hostage policy, then impulsively steals a bicycle belonging to an SS rider to ease her daily hardship. Isabelle brings it to Henri Navarre, who agrees to repaint it in exchange for a kiss; Isabelle complies, feels both briefly desired and afterward sad, and admits she still thinks of Gaëtan, ending the day repeating “if only.”
