Shadows of the Past

After the Joker and Harley Quinn get into a fight over Batman, Harley gives Joker a beating that knocks him unconscious. When he wakes up, he doesn't remember who the Joker is, recalling instead a life as a man named Jack Napier. Harley is desperate to figure out if this is a horrible joke, or if she really has lost her Joker forever...thanks to Eric Border for the suggestion! :-)
