In Our Father, Who Aren't in Heaven, Castiel shows Michael several of his memories of God's betrayals, including God's attempt to get Dean to kill Jack with the Equalizer and Sam shooting God with the gun. In Last Call, Castiel reveals that the Equalizer's bullet was actually a piece of Sam's soul and as a result, there may be a piece of Sam inside of God. However, Sam speculates that his dark dreams are Sam seeing God's possible endings due to the link created between them when Sam shot God with the Equalizer. In Proverbs 17:3, a resurrected Lilith destroys the gun. According to Amara, God can still do 'a few parlor tricks,' but is now too weak to even leave the Earth without her help which she refuses to give or to heal his wound. The wound in his shoulder will not heal and connects to Sam's same wound to an extent. In Raising Hell, it is revealed that the Equalizer not only wounded God, but also severely weakened his power and left him in a diminished state. Touching the wound gives Castiel disturbing visions of Sam as well. Castiel tries to heal Sam of his wound from the gun, though revealed it contained an energy that he never felt before.

In Back and to the Future, it is revealed that the weapon is in the possession of Winchester Family after Dean puts the weapon in the glove box of the Impala. However, the Equalizer at first seemingly fails to cause God any real harm and God decides to end the world, unleashing the souls of Hell upon the Earth, including many evils that were neutralized by the Winchesters in the past. Sam grabs the weapon and shoots God, hitting God in the shoulder and injuring himself at the same time. After he slipped his tongue and revealed that all of the events in the Winchester life were just a mere 'epic story', the brothers refused to kill Jack. In a cemetery, Dean confronts Jack with the Equalizer, but can't bring himself to kill Jack to God's rage, instead dropping the gun.

However, whatever happens to the target also happens to the shooter, meaning that whoever kills Jack will die as well. God presents the Equalizer to the Winchesters and Castiel as the only weapon capable of killing Jack.
