While in the hospital, a cop referred her to a self defense specialist. She went to him and began learning. Inspired by Gotham's new vigilante, the Batman, Selina decided to wear a mask - she adopted the cat as her other persona. Selina attacked her pimp - Stan. She was surprised to see her sister, Maggie, now a nun. She ran, and Sister Magdalene spoke with cops and began tracking Selina. Word got back to the Catwoman that her sister had been looking for her. She confronted her sister. After they spoke, Stan kidnapped the nun. The cops questioned Selina about the nun. Batman showed an interest in the pimp/nun situation and began investigating. The cops began tailing Selina hoping she'd lead them to Stan. As Catwoman, she tracked him and her sister. They were holed up in an abandoned theater. After a struggle on a catwalk, Stan and Magdalene fell. Batman saved the sister, but Stan died in the fall. Selina's friend, Holly, was at the scene when the cops arrived. Batman got Sister Magdalene to safety. After a three week stay in the hospital, Magdalene was visited by Selina. Holly came in beaten up, she said a cop did it. Catwoman went after the cop. Batman was able to stop her from killing the cop (he was tipped off by the nun). Catwoman kissed Batman, and catching him off-guard, she escaped.
