Sir Wilfull is Lady Wishfort’s forty-year-old nephew from the countryside. He is unrefined and ignorant but also very sweet and good-humored. Sir Wilfull wants to better himself by travelling to France. He has come to England to learn French but is easily corrupted by the debauchery that life in London offers. He gets drunk at Wishfort’s house and makes a bad impression on his cousin, Millamant, who his aunt wants him to marry. He doesn’t get along with his half-brother Witwoud, who is ashamed of him, or Witwoud’s best friend, Petulant. They often insult him and he patiently bears their slights. Intensely loyal to Mirabell, he helps him win over Lady Wishfort by pretending to accept being married to Millamant. He is also protective of his cousin Arabella Fainall and almost fights Fainall. By the end of the play, he has made friends with Witwoud and Petulant, who agree to be his travel companions to France.
