Batman defends his plans and criticizes them for not understanding the potential danger of a rogue Justice League before quitting. Batman explains to Superman the original plans were meant to only immobilize. Superman asks if Batman had a plan to stop himself if he himself were to go rogue, and Batman tells him that the Justice League themselves is his plan. With his trust in Batman assured, Superman hands him the Kryptonite bullet and teleports him out of the Watchtower.
