When Elie works in the warehouse, a young French girl works next to him; they never speak because he understands no French and she understands no German. One day Elie is the victim of being in the wrong place at the wrong time and suffers a terrible beating at the hands of Idek, who then sends him back to work as if nothing has happened.
In great pain, Elie drags himself to a corner to recover a bit. The French girl wipes his forehead with a cool hand and a mournful smile. Suddenly her gaze holds his, and he knows that she wants to tell him something.
After she seemingly ponders her next steps, she speaks to him in perfect German:
"Bite your lips, little brother . . . Don't cry. Keep your anger, your hate, for another day, for later. The day will come but not now . . . Wait."
This is risky because she has passed herself off as a non-Jewish Aryan and has thus been assigned as a forced labor inmate and not to a concentration camp, which would be far riskier.
Life is full of bizarre coincidences, and many years later, the two run into each other by sheer chance in Paris. She explains to Elie that she knew that she could trust him that day and that he would not betray her, which is why she risked exposing her identity to a boy in need.
