First, to test the chair, Batman asked it who killed his parents - it answered correctly: "Joe Chill".

Batman concludes that the Joker used the murders as a diversion, his real plan was stealing a truck full of his Joker-turning chemicals.

They go to Blackgate Penitentiary: at the crime scene of the Joker's murder of a judge, Batman found the fingerprints of one particular criminal: his parents' killer Joe Chill, who has terminal cancer.

Inside they face The Criminal, who intends to turn Chill into the new Joker because of his role in the Dark Knight's creation.

Jason leaves a letter for Barbara, where he confesses his love for her and is ready to abandon the Red Hood identity for good, if it means having a chance to be with her.
