they have a heartbeat. The souls cannot be killed, and injuries can only be inflicted to their eyes (it is shown the Devil can alter this rule somewhat, as he did in the episode "Encore"), by the living or dead. Even with the relatively restricted ways in which a soul can be harmed, as told by the Devil, they can only feel pain if it is inflicted by another escaped damned soul. Each morning the souls (including Stone) wake up in the clothing they were wearing at their time of death. Any material items they had in their pockets when they died continuously regenerate each morning. In Stone's case, this means he awakens to find his badge, his fully loaded service pistol, and $36.27—the amount of money he was carrying when he was murdered—on his person. This is a not-so-subtle biblical reference. Ezekiel 36:27 says "And I will put my Spirit in you and move you to follow my decrees and be careful to keep my laws" which is a succinct summation of Stone's new role. Normally Stone's items (gun, badge, etc.) retain no damage from day to day, even if they are hit by bullets. However this rule is inconsistently applied, as he takes his coat to a tailor in "Repentance", attempting to have it mended on a different day than when the damage occurred. Fighting villains The Devil informs Stone that because the eyes "are windows to the soul", Stone must pierce the eyes of an escapee to return them to Hell. This rule also applies to Stone himself; however, this was modified by the Devil in a special case when Stone had to return the man who raped his wife. To kill him, Stone had to employ the same rage as he did when he killed the rapist before. If Stone is returned, his mission would be considered a failure; therefore, he would remain in Hell and another person would be chosen to return the fugitive souls. The Devil has taunted Stone by reminding him of this and suggesting that certain escapees would be good replacements. However, in "It's a Helluva Life", an angel hints that the reason Stone was selected is because he was the only soul in Hell suitable for the task and for a second chance at life. Some escapees have other preternatural powers, such as the ability to control the elements or turn
