Carol Harding was Mason Harding's daughter, who came upon Captain America when he infiltrated the East Coast estate where she was recovering after a serious operation. The two talked and discovered a mutual attraction, agreeing to meet the next day on the beach. Cap met her as Steve Rogers, taking her for a horseback ride, wishing to keep her safe while Falcon and the S.H.I.E.L.D. agents were raiding her estate. When Steve scared a beach gang off, Carol realized he was Captain America.
