Selina explains that Batman just appeared in Gotham a while back and no one knows who he really is. Trying to make more sense of all this, Bruce asks Selina if she knows about Catwoman. This just worries Selina.

Confused by his memories of his previous life as Batman, Bruce goes to see Dr. Leslie Thompkins, the doctor that Bruce is friends with as Batman in his other life. She clears up that Bruce is simply identifying with Batman, because he feels that he's been given everything his whole life and the lack of real accomplishment is manifesting the fantasy that he is Batman, who has worked for everything he has and every deed is a great value. Relieved, Bruce determines that the nightmare is over.

He goes to his home, and is "his normal self" according to Alfred. Bruce is feeling happier than he has for years, however when he tries to read a newspaper, the words appear jumbled.

Batman arrives just shortly after and Bruce attacks him, saying that he's figured it out: this is just a dream. Batman questions him how he knows and Bruce explained when he tried to read, he couldn't because reading is a function of the right side of the brain, while dreams come from the left side. When Bruce can't explain how Batman is behind everything, he continues to fight him while Harvey Bullock arrive with the cops to call out as they just want to talk. Ignoring them, Bruce continues to fight and pulls off Batman's mask to reveal the Mad Hatter. Mad Hatter explains that this is indeed a dream world, which the real Mad Hatter invented to simulate everything that Bruce wants. Bruce is worried that this means his secret is out, but Mad Hatter assures him that the mind control device reveals nothing to the outside world. Bruce demands him that Mad Hatter release him, but is told there is no way out. Bruce looks over the side of the tower and realizes a possible way out.

E12: Freeze's Assistance
One night at Arkham Asylum, a group of masked men enter it and manage to silently take out any guards or anyone who pose a threat to them. Eventually they reach Freeze's cold cell and while he is asleep, the group manage to take Mr. Freeze with them, providing him with his suit and equipment, promising to break him out and help him cure his wife in exchange for them to come with them and give their boss a favor. When Freeze asks what the favor, the men tell him to ask their boss, so Freeze reluctantly agrees and wears his suit and arms himself with his Freeze Gun, escaping Arkham. Batman and Robin arrive later at Arkham, reviewing footage of the escape and the killed victims, noting that Freeze escaped but some men in masks took him. Batman then spotted some symbols on the masked men linking to the Gotham Docks, so the two vigilantes head there.

Meanwhile, Freeze arrives on a ferry ready to be set off and the man behind this is revealed to be Alberto Falcone. Alberto reveals that his mental instability has been causing him to lose the respect and power of his father, Carmine, so he wants Freeze's help to get revenge on Carmine and become a major figure in the criminal underworld. Alberto then added that he'll give Freeze a special place in his empire, promising he'll give him the necessary funds and resources in exchange to save Nora Fries. Freeze agrees to Alberto's proposition, albeit reluctantly due to his deranged behavior. Alberto notes that he is aware of Freeze being practically immortal, stating he wants to become immortal too, in order to outlive his family and become the top kingpin. However, Freeze warned Alberto that his state is a curse instead of a gift, to which Alberto denies. After much investigation, Batman and Robin are led to Gotham Docks, where Alberto's ship has already left, so the Dymanic Duo beat up an entire group of armed guards that attack them and interrogate the last one: who tells them he's working for Alberto and their ship has set off. Batman then calls in the Batboat to pursue the ship. Freeze eventually refused Alberto's offer of giving him immortality, saying no human deserves such a fate, before ordering him to get his wife so he can leave. Alberto refuses and has his mobsters deactivate Freeze's suit and then restrains him, then orders his research team to experiment on Freeze and create the serum to make Alberto immortal. Alberto then orders his men to execute Nora, to which Freeze shouts at him not to and threatens to kill him in the most excrutiating way if he does, but Alberto ignores his threats and smiles sadistically. Batman and Robin then arrive at the ferry, witnessing Alberto's thugs preparing to throw Nora's cryochamber into the sea, but they stop them and defeat them before saving Nora and reconnecting her cryo chamber to keep her alive. Alberto's new serum is then finished and he drinks much to everyone's horror, becoming slowly transformed and colder in his blood, much like Freeze.

The vigilantes then break into the room with Robin throwing a lasso at one of the mobsters, tying him up, before taking down the rest of the guards. Batman then helps Freeze out of his restraints and Alberto reveals a trigger used to blow up the ship, planning to test his immortality with such destruction while also killing everyone else to tie up loose ends and to eliminate the only people capable of stopping him. Freeze then punches Alberto in the face, causing him to bleed from his mouth, and the trigger is dropped on the floor. Batman stops Freeze from further hurting Alberto anymore, claiming he'll be punished in Blackgate for his crimes by staying there forever. Horrified by such a miserable fate, Alberto grabs a gun and shoots at the three in anger, but Freeze attempts to stop him only for Alberto to accidentally fall off the ship and into the raging seas below. Batman and Robin return Freeze to police custody and had attempted to search for Alberto's body but were unable to find him, presuming him dead or had just escaped with his immortality allowing him to survive.
