The city has gone dark, and is in total chaos, but naturally, the GCPD feels it is more necessary to focus on the crazy man dressed like a Bat instead, and even more naturally, Batman makes a fool out of them by jumping his car over their blockade.
With a blackout, a storm approaching, and Batman trolling the GCPD, Commissioner Loeb checks in on another problem across town, and it's a murder scene, where the victim's bones have grown like tree branches outside of the victim's body. It's the second victim found like this in short period of time, both of whom Batman had investigated, and both of whom were WayneTech scientists. There was a witness this time, a young Pamela Isley, who is more concerned with the plants in the lab, but mentions seeing a large skeletal looking man in the building.
In the meager Batcave, Bruce finishes work on a signal jammer which he hopes will help prevent the Riddler from possibly wreaking more havoc not he grid once it comes back online, then turns his focus on the blood samples from the two boney victims found recently. Turns out the compound used ended up being developed by WayneTech, under the supervision of one Dr. Karl Helfern, who gained a reputation of "Dr. Death" after many of his illegal experiments were discovered, causing him to go off the grid. Bruce has a lead on who he could possibly get info about Helfern from, but Alfred suggests he maybe get the police involved, something Bruce doesn't take kindly to, as he emerges from a rope ladder, to find James Gordon waiting for him at the edge of the hole.
Gordon welcomes Bruce back into town, and commends him on the bravery he had shown at ACE Chemicals, but Bruce doesn't seem to want to speak with Gordon, after his parents are brought up. Gordon mentions something about the night the Waynes died and how Bruce is probably angry at him for his part, which, yep, he is, and triggers Bruce to get angry about something we don't quite know yet. So Gordon cuts the personal chit chat and gets down to business, and brings up the scientists, but Bruce doesn't engage. So Gordon has one more question, and that's what's in the hole he just came out of. Bruce tells him to look for himself, and once Gordon does, Bruce hits a button that triggers a sonic signal to have all the Bats fly out at once, into Gordon's face, then tells him that the manor's generators attracts the bats.
That night, Bruce pays a visit to Lucius Fox who is happy to see him. The two speak about Helfern, and Lucius confirms to Bruce that he had been working on the formula, which was very unstable. Fox then continues to tell Bruce that Helfern had become very unstable as well, and last he heard, was working in underground labs for private, unregulated clients. There was one more thing Lucius forgot to mention... the compound was equally his as well, and he injects Bruce with a syringe to the neck, telling him that Dr. Death is coming, and none one can stop him. Sure enough, Dr. Death shows up besides Lucius saying he's just getting started.
Then we got a back-up of Harper and Cullen Row in the dark. Their dad is a still a dirtbag drunk, who leaves them in the dark, which Cullen is afraid of. But Harper puts Cullen to bed, trying to comfort him in the dark. She tells him that i's not just him who is afraid, everyone is, but there are special people who stand up against all the fear. This of course is cut with images of everyone from Batman to Luke Fox, taking part in their various adventures. Harper manages to wire up a lamp to a battery for Cullen, and which his fears being settled, he says it's okay to turn it off, and the two go to bed.
