Whom did rosalie remember when she saw emmett dying?

This question references the Twilight series backstory. Rosalie Hale was transformed into a vampire after being assaulted and left for dead by her fiancé Royce King and his friends. When she saw Emmett (later her mate) dying after a bear attack, it triggered memories of her own traumatic experience. Henry was her human friend whom she loved and who represents what she lost.
