Florine’s departure from Étienne Lousteau for Nathan is both a break in their personal relationship and a calculated change of sides within the Parisian theater and press worlds. Faced with no engagement, she accepts Nathan’s offer of a role and the prospect of a conditional contract at the Gymnase Theatre; in return, the documents and alliances around her help advance the journalists’ competing interests. The choice gives Florine a new protector, leaves Lousteau publicly wounded, and helps turn Lucien de Rubempré’s political and journalistic maneuvering into a personal quarrel with his former allies.

The Offer and the Change of Sides

Nathan had been in love with Florine for three months and was looking for a way to draw her away from Lousteau, for whom she had been a source of support. Her circumstances made his proposal effective: Florine saw herself without an engagement, and Nathan offered Coralie a role for her in one of his plays while promising to procure a conditional engagement at the Gymnase Theatre. Florine was ambitious, and the opportunity promised not merely work but a return to public life with renewed distinction.

By then, she had had time to observe the difference between the two men. Nathan is presented as ambitious in both literature and politics, energetic, and driven by substantial needs; Lousteau’s vices, by contrast, have weakened his capacity to act. Florine chooses the more forceful prospect. Her departure is therefore not described as an impulsive rupture alone: it is a decision made under professional pressure, with ambition and security bound together.

Documents, Patronage, and a New Position

Florine handed Nathan the letters associated with the druggist. Nathan arranged for Matifat to buy them back in exchange for a sixth share of the journal Finot wanted to obtain. Nathan had also secured Finot’s support by selling him that small share for fifteen thousand francs. The sequence links Florine’s change of protector to the bargaining over a journal and to the shifting alliances among the press’s participants; the personal and commercial transactions proceed together.

The change was made visible in Florine’s circumstances. She took a magnificent apartment on Rue Hauteville and openly accepted Nathan as her protector before the journalistic and theatrical worlds. Lousteau, who had been a source of help to her, was displaced not in private only but in public view. What he lost was both Florine’s attachment and the place he had occupied in her professional life.

Lousteau’s Injury and the Blame Directed at Lucien

Lousteau was so deeply hurt that he wept at a dinner his friends gave to console him. The gathering treated Nathan as someone who had played his hand successfully, but several writers, including Finot and Félicien Vernou, blamed Lucien for arranging the affair. They judged that, in bargaining over the matter and serving his new associates, Lucien had violated the most sacred laws of friendship. The charge sharpened because Lucien had relied on Lousteau as a friend and had made secret agreements with him.

The financial interests surrounding the quarrel made the injury harder to forgive. Finot accused Lucien of preventing him from earning fifty thousand francs by revealing the secret of the operation against Matifat. Lousteau, who lost a thousand écus, held Lucien responsible for that damage to his interests. The narrative presents wounded pride and money as mutually aggravating forces: a professional grievance becomes, through the intrusion of financial loss, an enduring personal resentment.

A Public Realignment

Within eight days, the dispute had intensified into a broader decision to bring Lucien down. Félicien Vernou, who hated him, undertook to keep watch on him. For the first fifteen days of the ensuing press battle, Lucien answered with a hail of articles in the royalist papers, especially in Le Réveil, sharing the critical campaign with Hector Merlin. Martinville was the sole supporter described as serving him without ulterior motives; the secret conventions joining journalists across political camps had been kept from him.

The division was visible at the foyer of the Théâtre du Vaudeville, formerly a meeting place for literary gossip and people from different parties. Lucien was no longer treated there as a friend by the wider circle: only men of his own party shook his hand, while Nathan, Hector Merlin, and Théodore Gaillard fraternized openly with Finot, Lousteau, and Vernou. Lousteau eventually shook hands with Nathan there. Florine’s choice thus helps expose the gap between public faction and private camaraderie: alliances that appeared divided by politics could reunite, while the man blamed for brokering the change was left increasingly isolated.
