Aunt Agatha

Although Bertie Wooster's Aunt Agatha never actually appears in "Jeeves Takes Charge," the details Bertie reveals about her as he narrates the story suggest that she disapproves of him. Bertie mentions in the beginning that his Aunt Agatha thinks that he is too dependent on Jeeves, going so far as to call the butler Bertie's "keeper." After Florence discovers that Bertie was unsuccessful in preventing his Uncle Willoughby's book from being mailed to the publisher, she breaks off their engagement and informs him that his Aunt Agatha discouraged her from marrying him.
