As Batman yells at Harley, demanding to know where Joker is, she leaves him to drown in the chemicals that made Joker who he is. Putting his respirator on, Bruce manages to escape the chemical vat just in time, before it at through his suit. Heading back to the cave, he alerts all his allies that Joker may individually target them, then heads up stairs to speak with Alfred. Not getting any response, Bruce begins to search for him, and all he finds is a small little present, wrapped in purple and green.
Inside the present is a cassette tape, the Joker's voice plays through as Bruce listens to it, claiming that he's planning an event, and he needed to "borrow" Alfred. Eventually, Bruce hears Alfred, remaining brave, remarking that it'll take more than a blindfold to scare him. Joker soon corrects Alfred, no blindfold... just ammonia burns, which he intends to do again, just for fun. Bruce crushes the tape before he can listen to anymore of Alfred's screams, and heads back out to search for his loyal friend.
Bruce firsts visits Gordon, informing him of the abduction, and that Joker has target him next. On the tape, a custom label that simply said "Gordon" was found, and Bruce wants to put him into protection. Gordon refuses, telling Bruce that he's faced the fear before, and won't go into hiding while his men are on the front lines. As Gordon looks at old pictures from when they first apprehended the Joker, he begins to start bleeding, and soon enough, blood is literally seeping from his body. Joker had poisoned him some how with a dangerous blood thinner.
Bruce manages to get a coagulant into Gordon's system and gets him to the hospital. Outside of Gordon's room, Bruce meets with Dick, and tells him about Alfred. Bruce keeps referring to him as "Pennyworth" until Dick, visibly distraught, tell shim to drop the act, it's Alfred they're talking about. Bruce tells Dick that he knows, after all Alfred was a father to him. He continues to tell Dick not to let any of the family know, as he feels that the emotion it would stir would cause them to want to hit Joker fast and hard, thus making them lose focus. Despite Dick's disagreement, Bruce asks him to help him out. He knows where Joker is going to strike next, the aqueduct, similar to one of his previous crimes, Bruce needs Dick at the pipeline, to prevent the fallout of what could happen.
On his way to the aqueduct, Bruce tries not to psych himself out by taking notice of how he'd usually be speaking with Alfred at this point. When he arrives, sure enough, the Joker is waiting for him. This time around, Joker has taken some liberties. Instead of the standard way things go down, Joker has already gone out of the way to just kill all the people who would have died from his classic plan anyways, pointing to all the bodies already in the water, and then proceeds to blow up the structure Dick is at.
Bruce loses it for a bit, and does just what he predicted everyone else would do, and gets sloppy. Many of Joker's chatter teeth pop up with wire, tangling up Bruce. With Bruce in a comfortable position, Joker begins to get down to business, and let's Bruce know what's going on. You know, the whole court jester to king thing, family makes him weak... if you paid attention to anything, you've no doubt heard it before. But Joker has another bit of info that he makes sure to say as loudly as he can for the Bat allies he knows are listening in... he knows who they are. He knows every single thing about them, and he's coming for them.
There's one more thing, Joker claims to have a secret that reinforces his claim that even Bruce knows the family makes him weak, a secret between just them, that he keeps in a tiny little book, with a bat-skin cover. Bruce tells the Joker he's lying, and Joker accepts the challenge, telling him, and all his allies that within 72 hours, they'll all be dead, and Batman will be the one to have killed them.
Meanwhile, in the back up, the Penguin has been called to a meet and greet within a church, only to find the top Lt. of each crime family in Gotham dead, and posed in prayer positions, wrapped in barbed wire. The Joker greet's "Ozzy," and clues him into his little plan, and drops off an invitation to the party he's planning.
