Two-Face is at odds with his ex-wife Gilda Grace Dent, as he believes their marriage failed because he was unable to give her children. She later marries Paul Janus (a reference to the Roman god of doors, who had two faces). Two-Face attempts to frame Janus as a criminal by kidnapping him and replacing him with a stand-in, whom Two-Face “disfigures” with makeup. Batman eventually catches Two-Face, and Gilda and Janus reunite. Years later, Gilda gives birth to twins, prompting Two-Face to escape once more and take the twins hostage, as he erroneously believes them to be conceived by Janus using an experimental fertility drug. The end of the book reveals that Two-Face is the twins’ natural father.
