Tenma visits Rudy, a criminal psychologist, who is working on cases involving a murderer named Jurgens.

Robert delves into Johan's past and makes a shocking discovery. Dr. Gillen speaks to Peter Jurgens, a serial murderer about Johan's possible involvement and gets a tragic reply. Johan confronts Robert about Stephen Joos. And Dr. Reichwen receives tragic news from the police.

Suspecting foul play in Robert's 'accidental' death fall, Dr. Reichwen makes some discoveries in his investigations. But as he later realizes, his investigations may have put him in harms way.

Dr. Tenma and Dr. Reichwen finally meet. Dr. Reichwen intends to proof Dr. Tenma's innocence in the homicides, but Dr. Tenma has other ideas.

Lunge tries to get into Dr. Tenma's mind by pretending to be him. Dr. Gillen learns something about Johan during an interview with a psychotic killer. Dr. Reichwen tries to warn the Lieberts of Johan's true nature. Dr. Tenma scouts for a perfect sniping location.

Dr. Reichwein reveals the true nature of Johan to Mr. Schuwald. Dr. Tenma gets ready to assassinate Johan. Lunge concludes that Dr. Tenma will kill Schuwald next. Lotte confronts Nina about Johan.

Lunge, from the BKA, learns that Johan may indeed exist. Nina goes into regressive hypnosis to learn more about the picture book and her past. Mr. Schuwald has a message for Dr. Tenma and sends Karl to Dresden to pass it to him.

Nina returns to the apartment that she lived in with her mother and Johan and encounters another memory. She then returns to Munich and Dr. Reichwein where she volunteers for hypnosis to find the truth behind these memories. After she nearly kills Dr. Gillen in a hypnotic rage, she leaves Dr. Reichwein's house to try to stop Tenma from killing her brother. Meanwhile, Suk and Vardemann team up to interview former residents of the Mansion of Red Roses to gather information on Franz Bonaparta's reading sessions with his picture books, and for Vardemann to find out more about his father's true involvement.

Egon Weisbach was one of the first investigators in the murder of the Liebert parents. On his last day on the job before retirement, he is escorting a convicted serial murderer but wants to know why he killed someone who did not fit his modus operandi. At the same time, Dr. Gillen is interviewing several murderers wondering why they killed someone who also did not fit their usual targets. Both realize that all these criminals committed murders outside their usual scope at the request of a young man, presumably Johan.

As time passes, more people in Ruhenheim are being shot dead by mysterious people and each other. Both Grimmer and Lunge determine that the owner of a local hotel is Klaus Poppe, also known as Franz Bonaparta. After subduing a man who was giving weapons to everyone in the town, they obtain information that one of the ringleaders is in a second hotel.

Tenma runs into Lunge, the latter apologizing for his previous accusations against Tenma. Nina and Dr. Gillen rush to Ruhenheim. After the winning lottery couple is wounded in an attack on Bonaparta's hotel, Grimmer rushes out to the streets to reason with the unknown assailants.

Lunge confronts Roberto, one of the ringleaders, in a hotel room. Both are subsequently wounded in the fight. Nina and Gillen arrive in Ruhenheim where they find a house containing drawings of the two twins by Bonaparta. This triggers a final memory and the secret to Johan's madness and motives, his quest for true solitude, as well as forgiveness for his actions. Bonaparta accompanies Tenma on his quest to find and kill Johan.

Bonaparta attempts to shoot Johan dead, but is gunned down by Roberto, who dies of his own injuries soon afterwards. With the massacre now over, authorities rush into the town and attempt to determine what happened. Just as an officer is about to arrest Dr. Tenma, an ambulance worker arrives asking for Tenma's assistance.
