Which character in 'Mansfield Park' is the manipulative aunt?

The manipulative aunt in Mansfield Park is Mrs. Norris. She is the widow of the clergyman at the Mansfield parsonage and the sister of Lady Bertram, making her Aunt Norris to Fanny Price and the Bertram children.

Mrs. Norris presents herself as a guardian of propriety and economy, but her behavior is self-serving and controlling. She helps arrange Maria Bertram’s marriage to the wealthy but foolish Mr. Rushworth, interferes in household affairs, and repeatedly treats Fanny as an inferior dependent rather than a beloved relation. Her apparent concern for rules often masks jealousy, opportunism, and cruelty.

Mrs. Norris is especially important because she helps expose the moral weaknesses of the Mansfield household. When Sir Thomas Bertram leaves for Antigua, he trusts her to help supervise the family, yet she fails to prevent the disruptive theatricals and does little to protect Fanny. She is sometimes confused with Lady Bertram, Fanny’s passive aunt, or Mrs. Grant, a neighboring character; neither fills Mrs. Norris’s manipulative role.
