WARNING: The following article contains spoilers for Batman: Curse of the White Knight #5 by Sean Murphy, Matt Hollingsworth and AndWorld Design, on sale now.

When Sean Gordon Murphy crafted Batman: White Knight, fans were left curious as to what was in the pills that cured Jack Napier, albeit temporarily, of his dementia as the Joker. It turned out Harley Quinn came up with the medicine in order to bring back her Jack, but as Batman: Curse of the White Knight rolls on, we find the Joker locked up in Arkham Asylum, meaner than ever.

Joker outed Batman to Azrael in this story so the latter could go on a murder spree, and even threatened to kill his lover for trying to destroy everything he built as the Clown Prince of Crime. However, Batman and Harleen Quinzel (as she's stable once more) have finally figured out a cure that could bring Jack back for good: his twin children.

Murphy has been coy about the kids, and hasn't used them as a McGuffin before now. With their genders and names still a mystery, it's clear Murphy was holding them back for something bigger in the sequel. Batman initially delivered the babies with Harleen in the bowels of Arkham, the place Joker is housed and where he discovered the dark secrets of the Wayne family. Harleen was then taken care of by Dr. Leslie Thompkins, because the babies were underweight and initially struggled.

Now, however, they're healthier, and Batman -- who arrived at a clever solution for the madman -- actually takes a chance and wants Harleen to bring them before Joker. He connected with Jack in the first book, and sensed a profound love for Harleen. There was something more to the man under the makeup, so Bruce takes a risk by telling Harleen these children can bring back the man she loves.

Harleen does so, and although Joker threatens her and the babies, when she walks away and tells him she loves him still, Jack suddenly reappears behind the prison glass. Harleen is relieved, and so too is Bruce, who needs her to probe Jack's memories in one more session to learn how to wage war on Azrael's army.

Jack recalls the church that Azrael has been using as his lair, but in the chapel he also decodes a message written in blood for the Caped Crusader. In the interrogation, Harleen asks what it is, but Jack is afraid to tell her, because it could destroy the Dark Knight. It remains to be seen how long the kids will have this effect on Jack, and whether he transforms into an allyy, as he hints that Batman will require help now more than ever.

He's cured due to love, for the moment. But even Harleen knows Jack could snap back at any time - and it's a risk she will have to take. Jack wants to remain in the light, however, so he finally may be able to put to rest his demons and the clown, as it will be intriguing to watch the criminal try to seek redemption and atone through fatherhood and another shot at heroism.
