The building that Babs had entered to confront Firebug has, well... it done blown up real good! As a good handful of people watch on as the building collapses, James Jr is amongst them, concerned for the fat of his sister... seeing as he's the one who wants to kill her. As the civilians dig through the rubble for Batgirl, James helps, but just until the point where she emerges, pretty knocked around, giving him the opportunity to make his escape.
Elsewhere, Harvey Bullock has just locked up the former Joker thugs Babs had tipped the police off of. Gordon attempts to speak with Harvey about the Firebug attack, but gets a notification on his phone telling him to go to the roof. Gordon finds Bruce waiting for him, and all we see is Bruce say: "Jim..." Then we cut to Gordon, visibly troubled, calling his daughter to make sure she's alright. He eventually tells Babs that Robin has died, worried for how the City will take the death of one of their heroes. Babs assures her father that she's alright, and as she hangs up, starts to cry a little, feeling awful for Bruce. She attempts to call Dick to speak to him about Damian, but Dick already knows, and doesn't really want to talk at the moment.
Knowing she still has work to do on Firebug, Babs toughs it out, and goes back to work analyzing some evidence, when her phone calls. She assumes it's her dad, but Jr ends up being on the other line, letting her know he's getting ready for them to play, so to speak. Babs basically tells her brother to fuck off and bring it, suits up, and heads back out to catch Firebug.
As Babs catches Firebug, who does the "You don't even know the kind of people I work for" sort of deal, James decides in order to start getting to his sister, it's time to kill their mother. Unfortunately for James, he arrives in the hospital to find his mother's bed empty, as a nurse tells him she checked out a few minutes prior.
With Firebug caught, Babs turns her attention to tracking her brother's phone, which she traces to a old home in a rundown neighborhood. But, Jr is nowhere to be found, only a pinned up bat, with "nice try" written in blood. Across from the house Babs got tricked into searching, James sits in what looks to be a young girl's room, hands covered in blood, then calls his mother, who ended up seeing James coming, and had just dodged him at the hospital. He tells his mother that she will meet him, or else he'll, and I quote "kill her" and then "make dad eat her." YEP.
