Years ago (note: I refuse to acknowledge any specific year number given in the New 52, because it's stupid and complicates too much) Gotham looked as if it hadn't been inhabited for decades, as a kid emerges from a flooded subway tunnel with a fish to eat. The kid is soon attacked by masked gang members, but before they can do any harm, a tattered Batman comes to the kid's aid, tying up and knocking out all the gang members. The kid looks up to Batman and says that everyone thinks he's dead. Apparently someone has been spreading that rumor ever since said person "killed" the city. Batman says this is a good thing, as whoever they're talking about won't see him coming.
Remember Batman #0? Well, Bruce is still gunning for the Red Hood Gang. Again, a masked Bruce finds him at odds with the Red Hood gang, who has the truck he's driving (containing targets to be killed) surrounded. Young Bruce, he's pretty god damn reckless, and despite Alfred pointing out his shoddy math, Bruce fires a grappling hook out the front window, attaches it to a crane, drives off the platform he's on, swings the truck over a body of water, where the men fall out the back, and ultimately to safety, away from the Red Hood and his gang. Bruce emerges from the water, and straight up gives the Red Hood the finger.
Back in Bruce's current base of operations, Bruce speaks with Alfred (who at this point, is still very against this whole deal) about the Red Hood gang, how no one knows who the boss is, and how the members could literally be anyone who has been blackmailed into joining. Through Bruce and Alfred's conversation, we learn that Bruce is still legally declared dead, and the only person who knows he's alive is Alfred... and his uncle Philip Kane, who awaits Bruce outside his building in crime alley, having been looking for Bruce for years, but admits he probably should have kept tabs on Alfred (who for some reason isn't too pleased to see him) from the start.
Philip convinces Bruce to take a ride with him, as he brings his nephew to the new Wayne Industries building, where he tries to convince Bruce to come and be the new public face of the company. Philip explains that public perception of the Kanes has never been great, and even though the Waynes and Kanes merging (Thomas and Martha's wedding and the two companies) somewhat improved, it would be better for the business if Bruce Wayne was the face of the company. Bruce declines his uncle's request, telling him that he didn't come back to Gotham for that reason, as Bruce puts it, that's not who he is. Philip then asks who Bruce is then.
We flash back to a time where Bruce was a child, he enters a rather large garage to find his father working on a car. Thomas asks his son what he loves about Gotham, as he knows Bruce has been sneaking away into the city after school. Bruce tells his father that the city allows him to be anyone he wants. Thomas is somewhat amused by his son's answer, and brings up something Alan Wayne used to say, about fate forming in the dark, then shows Bruce something Lucius Fox cooked up, a sphere that uses a 360 degree camera to 3D map a confined space, even in the dark. Before he can explain more, Thomas is called away on business. We later see a young Bruce throwing the camera down what would eventually become the Batcave.
Sometime later, night has fallen and Philip is meeting with his "strategist" in hopes they can come up with a plan to fix the current business problem at hand. The solution? Philip needs to kill his nephew, Bruce Wayne. Oh, did I mention the strategist is a young Edward Nygma? That seems pretty important.
In the back-up, a 19 year old Bruce is in Brazil with the man who taught him how to drive (which was a callback to the Red Hood wondering where Bruce had learned to drive, in the main feature). Bruce's "instructor" is a slick, golden tooth, drive fast sort of guy... and also a criminal, as they're being chased by the police. Bruce get's a lot of philosophical nonsense about how the police want to chase him, and yadda yadda yadda, but when the guy riding passenger takes out a rocket launcher to shoot at (and probably kill) the cops, Bruce veers off the road, and into a building, leaving the dude to be caught by the police. Because that ain't how Bruce rolls!
