Ruby is a fictional character on The CW Television Network’s Supernatural portrayed by Katie Cassidy and Genevieve Cortese. Created by the writers in order to expand on the characterization of demons within the series, she first appears in the third season, rescuing Sam and Dean Winchester, and continues to assist them throughout the season. By the fourth season, she has won Sam’s trust and begins training him to kill demons with his powers, though Dean remains fearful of ulterior motives.
