Fan Casting Batman: Earth One Season Three

Underneath Gotham, Bruce, Alfred and Jones find an old subway station that connects Wayne and Arkham Manors to the rest of the city. Bruce plans to use the place both as a bunker to hide his new Batmobile and as a safehouse to expand his operation as Batman. Suddenly, Gordon calls him through the Bat-Signal to alert him of criminals with military-grade weapons. Batman arrives and stops them, with the last man incapacitated by the cat-burglar he met a month earlier, who escapes with the criminals' stolen money. Jessica – wearing a mask – is escorted by Bruce to a press conference where she opens a homeless shelter named after Harvey. During the conference, Alfred gets a call from the Gotham Mental Hospital; there, he and Bruce learn that the elderly man who broke into the psychiatric hospital in Maine is actually Adrian Arkham, Bruce's maternal grandfather, thought to be long-deceased. Skeptical that his grandfather might be alive, Bruce still takes Adrian to Wayne Manor.
