Jesse Turner

History
Jesse Turner's powers developed as soon as Lucifer was let out of the Cage during the first attempt at starting the Apocalypse. When Sam & Dean Winchester tried to get him to use his powers for good, the demons were trying to get him in their corner to present to Lucifer. Jesse took a third option and high-tailed it to Australia to sit out of the Apocalypse.

Shortly after, Gabriel (who had faked his death at the hands of Lucifer) found the boy and offered to train him to use his powers while they both lived in a pocket dimension while the Apocalypse played out.

He's All Yours Now
Years later, Gabriel would tire of Jesse as the boy had grown up to be EXACTLY like his Uncle Gabriel. It didn't take long for the Archangel to track down Adam's group and trick them into taking Jesse in after trapping them in a hellish game show setting.

While Jesse was antagonistic at first, he soon came around when the boys had been captured by Crowley's demons. Helping free his new guardians, Jesse agreed to play nice for the time being. It was around that time that Lucifer had been severely depowered by Amara, resulting in Jesse's powers being cut down drastically.

No one realized that the more Jesse used his powers in this state, the weaker he became and eventually was on the brink of death. Having to use his powers to escape Azazel's disciple Dawn completely drained him, and it was only through Lucifer reaching out to him from Apocalypse world that Jesse's life was saved, although the move caused him to become addicted to demon blood. There was another catch as well: Jesse had to promise Lucifer he'd open the portal to free Lucifer once the boy was back to full power.

After the discovery of Adam's son Hunter, the two became quick friends. Jesse even willingly unlocked Hunter's powers, a move forbidden by Adam so that Jesse could train the boy to defend himself. When Lucifer demanded that Jesse free him at once, Jesse sent Hunter home from a training exercise but forgetting to relock the boy's powers.

After freeing Lucifer from Apocalypse world, Lucifer thanked Jesse by snapping his neck.
