Summary of Stephness: Steph mostly serves as another, somewhat disgruntled (because of her distrust of superheros at this time) helper in the fight against the anti-male bioterrorists. She and Cass apologize to Catwoman, Poison Ivy, and Harley Quinn at the end, acknowledging they were too hasty to judge, and that the trio of Sirens are, as Cass puts it in one word, "Heroes."
