At Deadshot's funeral (he shot himself through the chest, to shoot Regulus last issue), Harley Quinn, Captain Boomerang, and Amanda Waller, all stand at attention, as Deadshot receives his military style service... until the rain starts... green rain, knocking out all those at the funeral, except Harley, who seems to have an immunity to it. Whatever could that mean? Oh wait, I know! Puddin' is home!
AND BOY IS HE ABUSIVE!
While Harley is initially happy to see Joker, Mistah J isn't all that happen to see her. He knows what she's been up to, and someone has to pay for it. Captain Boomerang? Nah, Harley doesn't care about him. Waller? Not her either. But there's one person Harley does somewhat care for, and that's the deadman, Deadshot, and joker has no problem with desecration. Joker hits a nerve with Harley, who points at gun at him to get him to stop. Despite him knowing Harley won't pull the trigger, Joker offers her up a deal, do something for him, and he'll leave her new boyfriend alone.
Then there's a cut in time with Amanda haven woken up visiting all the incarcerated members of the Squad... that's not why I'm covering this, so, lets move on!
Having done what Joker asked (see Batman #13), Harley calls out to him, asking if they're set. But before she goes, Joker asks from the shadow who's "driving." Harley, or Dr. Harleen Quinzel? Harley tells him it's just good ol' her, but Joker doesn't quite believe her, as he soon puts Harley in a noose made out of heavy duty chain.
