It's the New 52! Time to learn about Hush and his slightly tweaked history!
Everything is a bit awkward in the cave. You've got a beaten up Batman, Julia Pennyworth tending to him, and Batgirl, Red Robin and Red Hood just sort of sitting there like "huh?" Once introductions are made, Bruce gets to the point: Hush. He's behind it all, and right now the family needs to do their best to stop the riots in Gotham. As the family disperses, Bruce takes Julia to visit her father in the hospital.
Meanwhile, Bard is announcing martial law in Gotham, while Stephanie hitches a ride to the prison her father is being detained in, and after confronting him, realizes that he's hacked into her account online and has posted a $100,000,000 bounty on her head. Run Steph, run!
While visiting Alfred, Bruce tells Julia about Hush. His story remains somewhat the same, but now it seems he was a little more obsessed with being like Bruce in their youth, to the point where he'd tell girls that he was Bruce Wayne, which Bruce found to be a little fucked up. One thing leads to another, Tommy figures out Bruce's secret, and Hush is born. After the visit to her father, Julia seems fully on board with taking her father's place in Bruce's operation...
But Alfred's troubles are not over, as Hush, posing as Doctor Tommy Elliot, has him moved to Arkham, where Joker's Daughter awaits him, claiming he has a new master to serve.
