Well, it didn't take long for Casey to escape the GCPD, as your generic cop reports to Gordon that there's no way Casey is who she says she is, due to there being a death certificate. Gordon goes to speak with Casey in an interrogation room, but she's already escaped, and heading for the Bat-Signal on the roof.
Meanwhile, in Santa Prisca, Bane is less than impressed with Calvin and his allies, claiming to know everything about Calvin, and taunting his constant running from conflict. But, Calvin is who he is, and his allies scramble, each chased by one of the venom freaks.
In Gotham, turns out that Batman isn't the first to respond to the Bat-Signal, as the Butcher shows up to finish the job he had planned for, killing Casey.
In Santa Prisca, Anya gets cornered by Malicia, but is confident in her abilities with swords, as she name drops her sparring partner, Ra's al Ghul. Meanwhile, Edgar and Joey have The Professor command the less-than-intellegent Brute to attack them.
Calvin is Bane's target, and he's been lead to the depths of Santa Prisca, where he was raised. Bane believes Calvin is trying to get an emotional response out of him, but Bane tells Calvin the difference between them is that he found strength in his prison, Calvin ran from it.
In Gotham, Casey isn't doing too well, but Batman eventually shows up, and manages to string The Butcher up by a cable. When Batman turns his attention to Casey, she weakly tells him about her daughter, and that he and Calvin must save her. The police show up, but Butcher has already freed himself and escaped, so Batman has them get Casey to a hospital.
In Santa Prisca, all of Calvin's allies are able to beat the venom freaks set after them, and retreat to an advanced jet, hidden on the roof of the prison, to wait for Calvin, who is still dealing with Bane. Calvin has had enough of Bane's psychoanalysis, and tells the brute that he's not weak due to his willingness to survive. Calvin tells Bane that he's already won, because the real reason he brought Bane down to the depths of the prison, is because he studied the architecture, all he has to do is grapple up a pipe Bane can't fit into, escape, and warn Gotham about the war that's coming, and that's precisely what he does.
In the plane, Calvin tires to contact Casey, but Batman answers. Calvin tells Batman to put Casey on in ten seconds or he's out, but Batman breaks the news that she's been seriously injured, and he's not sure she'll make it.
Meanwhile, back at Santa Prisca, Sebastian Clarke tries to urge Bane to continue his war, so he can destroy the Court of Owls, but Bane sees no purpose in it, as his chance to take Gotham has been lost... not quite says a mysterious man in a bowler hat. Bane demands to know who the man is, and he introduces himself as someone who can offer a better solution than Clark. This of course doesn't please Clark too much, as he starts yelling at Bane, which of course Bane doesn't take a liking to, and silences Clark in his own unique way.
Bane again turns his attention to the mysterious man, and asks to know more about this "Society," to which the Outsider will gladly answer...
EDIT: James Tynion let me know that we've yet to see the last of Sebastian, so I was wrong on his ultimate fate, but the unclarity was still there.
