Lind is Marion's classmate and friend at a French academy, alongside Jacques and Claude. He presents a calm and collected demeanor, contrasting with Jacques' straightforward personality. Lind develops romantic feelings for Ledania, the mayor's daughter, sparking a bitter rivalry with Jacques as both compete for her affection. This competition fractures their friendship and fuels Lind's growing envy.

Discovering Ledania harbors unrequited feelings for Marion deepens Lind's resentment. His jealousy drives him to betray Marion by revealing Marion's secret affair with the married Sarah to her husband, Count Cluny. Lind intends this revelation to cause Marion's expulsion from the academy, removing him as a romantic rival for Ledania.

This betrayal intensifies the conflict between Lind and Jacques, culminating in a pistol duel to the death. Marion intervenes, halting the duel but suffering an injury. Following this incident, Lind departs the academy, transfers to a school in Paris, and severs ties with his former friends.
