Harley Quinn and Joker try to ambush James Gordon at the dentist office, but Batman gets the drop on them
and even mocks Joker for being too predictable. They escape, but Joker's pride is wounded, and Harley
can't even get a smile from him. Eventually tossed out with the hyenas, she blames Batman for standing
between her and Joker.
In flashbacks, we see Harleen Quinzel’s past — her gymnast scholarship to Gotham University, her seductive
manipulation of professors, and her eventual posting at Arkham Asylum where she meets and falls in love
with Joker, breaking him out to become Harley Quinn.
Determined to remove Batman from the picture, Harley crafts a meticulous plan to capture him, dangling
him over a tank of piranha. But Batman plants the idea that Joker would be furious if she killed him alone.
Convinced, she calls Joker, who rushes to the scene.
