After years of learning how to become a better person, Harley Quinn's path to redemption in the comics is seemingly complete.
In the comics, Ivy leads Harley to an off-limits section of a museum to a case containing a priceless diamond. Ivy tempts Harley to steal it, as the one diamond alone will allow the lovebirds to leave Gotham forever. Despite how tempting the situation was, Harley refused. She endured both physical and emotional by her Mr J, and had previously tried, unsuccessfully, to escape from him.
The book showcases Harley's redemption arc and while she retains her zanier, unpredictable personality, she's clearly on the good guy's side. More importantly, the world around her is slowly recognising that as well.
