Orgon's family is up in arms because Orgon and his mother have fallen under the influence of Tartuffe, a pious fraud (and a vagrant prior to Orgon's help). Tartuffe pretends to be pious and to speak with divine authority, and Orgon and his mother no longer take any action without first consulting him. Tartuffe's antics do not fool the rest of the family or their friends; they detest him. Orgon raises the stakes when he announces that he will marry Tartuffe to his daughter Mariane (already engaged to Valere). Mariane, of course, feels very upset at this news, and the rest of the family realizes how deeply Tartuffe has embedded himself into the family."
