inmates of Arkham, including Ventriloquist and Scarface, Harley Quinn and the Scarecrow, Wayne finds it odd that none of them are willing to say anything and only heap compliments on Bolton. Wayne also notices that the guard is able to quiet them with a mere glare. However, after slyly suggesting a possible extension of Bolton's contract to eighteen months, the inmates panic and finally admit to Bolton's reign of terror. Enraged at the inmates ratting him out, Bolton assaults several Arkham orderlies and attempts to attack his accusers only to be stopped by Wayne tripping him.

Batman and Robin find and defeat him before he can dispose of the hostages. Deemed insane himself, Lock-Up is then imprisoned in Arkham Asylum where the inmates he once tormented mock him, and the Scarecrow vows revenge against him. When placed in his cell, Lock-Up quotes "They thought they could trap me in a world with lunatics, but I
