As a member of Titans East, she has a rematch with the Ravager and a brief confrontation with Robin, after which Robin injects Cassandra with a counter-serum (prepared in case Deathstroke regains control of his daughter), and she is apparently freed from Deathstroke's control and vows to kill Deathstroke to revenge herself.
