Both Batman and Harvey Bullock continue to investigate the death of Elena Aguila, and once Bruce is done investigating her car that was thrown into the bay, he sends a tip over to Bullock, who still seems desperate to connect it to Wayne. After going through the car, knowing Batman has been there first, Bullock and the rest of the GCPD clean up the scene left by Batman, including Sumo and the kids he was trafficking, as well as looking into the details of a single shipping container missing from the dock.
That morning, before heading back into the cave, Bruce finds Elena's daughter on the docks by herself, pretty depressed, and potentially following some drug use, and gives her one of those inspirational Batman speeches, before disappearing. Meanwhile, we see a bit into Harvey's personal life, and boy does he love cats. Harvey also loves when his investigations link back to Bruce Wayne, so he's going to love that the shipping container that was missing got linked back to some Wayne Enterprises accountant, whose probably on the Kings of the Sun payroll. As that guy is trying to get rid of the paper trail, Bullock pays him a visit.
Elsewhere, Batman is on the trail of The Squid, which brings him to the old Aquarium, which Alfred points out is a bit cheap for a guy named "The Squid," but Bruce reminds him that Gotham villains aren't that subtle... Highlighted by the point that Bruce gets attacked by a giant squid not too long after that, while The Squid and his brother watch on.
But of course Bruce has got some gadgets to help him electrocute the squid and dump it into the ocean, but once he's gotten back on to dry land, The Kings of the Sun have shown up and are in a standoff with The Squid and his men.
