She was one of the main victims of Gríma Wormtongue's poisonous counsel; he convinced her that the Rohirrim were doomed to become nothing and that she would spend the rest of her life as the nursemaid to her uncle Théoden as he declined, rather than do great things as she wanted. As a result, she became essentially suicidal, wanting to ride with Rohan's armies and die in battle. After meeting Aragorn, she developed something of an unrequited crush on him, which, as her brother Éomer later realized, was the last straw. Disguising herself as "Dernhelm" and taking Merry with her, she rode with the rest of the Rohirrim to break the siege of Gondor. When the Witch-king of Angmar went to go after her fallen uncle, she fought him and, with Merry's help, destroyed him. She was gravely injured as a result, but was later cured of her physical injury by Aragorn. However, her first wish upon being cured was to be allowed to go out and die in battle, but, as the armies had already left for Mordor, she stayed in the Houses of Healing. There she met Faramir, and together they helped each other heal and dealt with being left behind. Éowyn decided that she would rather live than die. After Sauron was defeated she and Faramir married.
