Slade Wilson, also known as Deathstroke, met Lillian Worth on a search-and-rescue mission a few years after his divorce from Adeline Kane. His mission was to make sure that she escaped war-torn Cambodia safely. After an intermittent love affair with Wilson, Worth gave birth to a daughter whom she named Rose. Believing it to be in the child's best interest, Worth kept Rose a secret from Wilson. Worth eventually settled down at a brothel in New York City, and during a time when Deathstroke was injured and a fugitive from the law, Worth took him in and nursed his wounds. Deathstroke's butler Wintergreen discovered 14-year-old Rose and suspected that she was Deathstroke's daughter.
