Something is up with the kids Pyg supposedly infected, and Tim Drake knows it. Doing scans on all the kids who were kidnapped by Pyg, Tim figures out that they were all showing odd flue like symptoms before they were brought to the museum, and it's all connected to where they live, a projects building in the Narrows... the same one Harper and Cullen row live in, and uh oh, Cullen feels sick!
Elsewhere in Gotham, at the Gazette, Vicki Vale berates the newest young hire at the paper for getting an easy in at the paper, where she had to work for everything. Warren, the guy who broke the story on the Joker, calms her down and gives her some leads to a story he's received tips on, offering her a chance to cover something other than the Gordon case. Naturally, Vicki takes the scoop, but is forced to bring along the new kid Joey, for the ride.
In the Narrows project complex, Tim is scanning another kid he believes to be infected by... whatever, and knows Batman is watching him. Things are tense between the two, Tim mentioning how messed up things have been since Joker, Damian and now Nightwing, but nevertheless, reveals his findings that these kids are infected with some crazy form of nanobots, for some unknown reason. Bruce seems to recognize them, but doesn't say anything, telling Tim that any weirdness from him at the moment is about the city, not what's happened between them recently, and leaves.
On the streets, Vicki brings Joey into the Narrows to follow up on some leads... then find the biggest, scariest looking motherfucker, and starts asking him about Carmine Falcone, seemingly fully knowing how dumb she's being, but who cares... Well, maybe she'll care when all the thugs she's "interviewing" pull knives on her. Before anything bad can happen, Harper shows up and tasers the thugs, telling Vicki and Joey to follow to her apartment, where they'll be safe.
Inside Harper's apartment, she berates Vicki for being so stupid, which Vicki doesn't seem to care about. Long story short, the thugs kick down the wall, but a story above, the nanobots in that kid activate, attack Tim, and have him crashing down through the ceiling. Shit goes bad, Nanobots attack the thugs after they attack first, Tim finally finds a way to shut the bots down, but they find their way into Cullen. Yeah, things are crazy! You know what else is crazy? Remember the Batman #22 back-up with the guy who trained Bruce Wayne with all sorts of technology? He's responsible for the nanobots! Why? I don't know!
