No longer frozen, Nora does not have long to live. In desperation, Freeze bribes an old colleague into helping her. This leads to Freeze hunting down Barbara Gordon, one of the few women on hospital records with Nora's rare blood type. Freeze plans to use Barbara for a fatal organ transplant to save Nora, but Batman intervenes. Nora is ultimately cured by Dr. Lyle Johnston of Wayne Enterprises.
