Storylines
Beth Kane was presumed dead in a car crash that killed her mother Gabi Kane. Years later, she resurfaced as the mysterious Alice and formed the Wonderland Gang. She formed a relationship with Chuck Dodgson and he became her right hand man and second in command. Alice kidnapped Sophie Moore and tried to force her father, Jacob, to choose between her or the city. She was stopped by her twin sister Kate Kane, who had taken up the mantle of Batwoman.

Alice later met with Kate and toyed with her on whether or not she was Beth. Alice was apprehended, but managed to escape and revealed she knew Kate was Batwoman. In an effort to get Dodgeson back, who had been captured by Kate, Alice made a deal with her that she would not kill for twenty four hours.
