Adeline Kane

Adeline had been brought up as a jet setting, wealthy, careless playgirl, despite being trained by a father who had worked with Chinese guerrilla forces. But, after a traumatic first marriage at nineteen, she joined the U.S. military, where she met, trained, and married Slade Wilson. After Slade left the military, due to a) the supposed failure of the experiment he had undergone and b) his refusal of a direct order so that he could retrieve Major Wintergreen, Slade and Adeline took up the socialite lifestyle Adeline had been raised to.

Unbeknownst to her, Slade was using his hunting trips to gain clients for his mercenary side job, which resulted in the kidnapping and near-death of their younger son, Joseph. Enraged and betrayed by Slade's prioritization of Deathstroke's honor code over their son's well-being, Adeline shot her husband and, when he survived, served him with divorce papers. In the long run, that might have been a poor choice. Grant, who had idolized his father, rebelled against his mother and ran away to New York, where he ran into the Titans and ended up dying due to his alliance with the H.I.V.E.. Slade vowed to pick up his dead son's contract against the Teen Titans; Adeline promptly interfered. She blamed Slade for Grant's death. Due to Adeline's intervention, Joseph, who had been working with her, joined the Titans as Jericho.

In the long run, that also might have been a bad choice: Joseph eventually became possessed by the spirits of Azarath. Begging his father to kill him in order to prevent the corrupted spirits from achieving their purpose, Adeline's only remaining son died at her husband's hand. Adeline found this out from one of her Searchers Inc. agents, rather than from Slade himself, which merely cemented her long-held grudge against her ex-husband.

Slade, however, held no grudge against her, keeping an eye out for her safety and attempting to aid her when he thought he could get away with it.
