Disguied as a pharmacist, Léandre is able to talk to Lucinde while Sganarelle distracts Géronte. Géronte, however, turns his head and sees Lucinde talking. Sganarelle then tells the young couple to run away. Lucas, still mad that Sganarelle hit on his wife, tells Géronte that Sganarelle was in on Lucinde's elopement, and Géronte takes out his wrath on the fake doctor. Then Léandre comes back with the news that his rich uncle has died and he's inherited his fortune. Géronte happily agrees to Lucinde and Léandre's wedding. Sganarelle is released and his healing powers go to his head, while Martine comes back to him, humbled by the thought of being married to such a wise and knowledgeable man.
