"A Mother of a Father's Day"Edit
Batgirl realises that it's Father's Day, which depresses her. She discovers that her new friend Brenda Miller doesn't really like Father's Day either, and as they talk, the question of her mother's identity comes up. Both Batgirl and Batman suspect that Shiva might be her mother, but they are not sure, and Onyx, although she knew Cain and Shiva at the appropriate time, has no idea if it might be true. Batgirl visits her father in prison, but it soon becomes clear that he'd quite literally rather die than tell her.
