Jack is only interrupted when Dean is forced to shoot him to get Jack's attention. Buddy shoots at Sam, but Jack uses his power to cause the bullet to ricochet into the wall.

Elsewhere, Lucifer mentioned to Crowley that his son's power is a chip off the old block. Driving back, Dean stops at the side of the road before they get back to the bunker in order to talk to Jack. Mrs. Butters accuses Jack of being bloodthirsty and dangerous, insisting that he is despite Jack's claims to the contrary.

Jack orders him to back off but Zachariah ignores him and advances as Jack uses his power to lift him and destroys him as the colony watches this feat. Jack and Mary are found by Bobby who blames Jack's use of his powers for how the angels found them.

Jack is then fingerprinted and sits with Clark who asks what Jack is on.

Just as Buddy is about to shoot them, he sees Sam return and readies to kill him by tricking him into coming to him. Seeing the sheriff's gun, Jack initially takes a defensive stance until Sheriff Barker assures him she only wants to help him. He returns to the house of his grandparents but Mrs. Kline reveals that she has discovered his deceit on Kelly's whereabouts and shouts at him to tell the truth. Sam and Jack are placed in a holding cell, while Dean explains the situation to the sheriff.

Dean notices Jack is behaving oddly with his new pet snake and takes him on a trip to see Donatello who Dean calls their expert in a lack of soul. During labor, a rift to an alternate reality is opened and Team Free Will uses it to trap Lucifer within but he drew Mary with him as they tried to push him in.

The action of the sigil causes Jack momentary discomfort. As Mrs. Butters prepares celebrations for the various holidays, Jack enters the kitchen in his pajamas, leaving Mrs. Butters confused as to what Jack is. He is soon chased by a black ooze. Realizing his days are limited, Jack resolved to get enjoyment out of his remaining time, as Dean decides to help him by teaching him how to drive, by using the Impala and Jack is excited by it.

The child kicks moments later and Castiel feels it.

As they depart in his truck, Castiel tells Kelly that the child showed him "the future". Serafina tells Jack that making his body strong and reclaiming his human soul was all preparing him for this moment. Castiel insists that Jack never needed absolution from the Winchesters or him and that they don't care about Jack because he's useful or fits into some grand design, they care because of who Jack is as a person. That night, as Jack prepares to depart with Lucifer, he receives a prayer from Sam that the Winchesters are in danger. They then ask if she isn't killing anyone who was as she deduces it to be her old lover Buddy who is also shifter and enjoyed killing just to torment others.

In Last Holiday, Jack has been holed up in his room for awhile dealing with the return of his soul and all of the burdens that return to him because of it. After escaping the two spot figures approaching them and hide, they are found by the people who question if they are human or a threat. As Kelly continues to insist on her son's goodness, Castiel asks her if this is true, who will guide and protect the child after his birth since Kelly will die in the process. Finally, with a scream from Kaia, the two emit a yellow glow that opens a rift and sends out a wave of energy that disintegrates the attacking angels. In the main universe, Gabriel is informed by Sam of his nephew and how he is in the other universe. However, once it starts, it can't be stopped.

In addition, the sheriff has video footage of a masked person crouched over the body and Jack notes that the horrific nature of the crimes seems almost demonic.

Apparently, when Earth was created, humans started praying to things like harvest and luck instead of Chuck, which of course pissed that narcissist off.

Jack is surprised as he brings up the brothers' statement of nothing coming back from being burned but soon hears it is partly because of him begging for the angel's return is why he has come back.

Dean sends Jack to get his things, but Sam refuses to join them in the hopes of finding another solution.

At that moment, Jack collapses in pain, his eyes glowing and the skin around them burning. After getting confirmation that Jack was who the girlfriend saw, the Winchesters come to the wrong conclusion that Jack murdered Derek and is now looking for Lucifer as they saw the picture of the apocalypse world. Sam confirms he wants to save his mother but states he does care for Jack and promises not to allow Dean to hurt him as they go off to their quest.

Sam returns to the house to find Kelly dead, along with a trail of scorched footprints leading to the nursery.

Jack returned to the camp where he decided to hear Lucifer out, despite protests from Castiel but Jack insisted on talking to his real father. Unfortunately, Dean’s luck doesn’t increase with the victory and the boys realize someone is skimming luck from each game. They contact Rowena who at first is against helping the son of the devil, she is swayed when Jack talks to her and thanks her for her part in the Exodus from Apocalypse World. However, after Castiel leaves, Jack coughs up blood and is shown to have been doing this frequently. Jack tells Sylvia how he lost his mother with Sylvia having had a similar experience a few years before. During Devil's Bargain, the Winchesters are informed by Castiel about Michael and realize Jack, as well as Mary, are in danger.

Jack eats a burger and drinks beer the same way (and the same time) as Dean does, but this only serves to annoy Dean. As he tried to leave, Sam stopped him and tried to talk him out of it but Jack was only swayed when Lucifer intervene since his plan was dangerous and he conceded. After being kidnapped by Castiel, Kelly insists on the goodness of her child. Next, he goes up against a man named Joey 6. Dean, on the other hand, takes Jack’s face in his hands, with Jensen Ackles conveying the many mixed emotions Dean’s feeling at that moment. In this bar, though, you don’t buy into a game with money, you buy in with luck, which you transfer into a coin. Jack realizes that Adam hates God which he confirms, stating that he's wanted this for 300,000 years which is how long it took Adam to figure out how to do it too. After escaping from the alternate reality, a weakened Lucifer tells Castiel that he needs Jack's help to defeat the alternate reality Michael.

In The Big Empty, Jack is watching videos on the computers before he is invited by Sam to join him and Dean on a mission though he refuses due to Dean's distrust of him while also revealing he is aware Sam wants him to control his powers to save his mother.

Excited by this, Jack greets the newly resurrected Angel with a hug and proceeds to tell everyone he found a case. Jack listens to Sam's phone call with Dean and suggests breaking out of the cuffs to get them out of the dungeon. In the aftermath, Jack joins the Winchesters in staring in amazement at Lucifer's corpse before Michael suddenly betrays his deal with Dean, takes full control of his body and disappears. Jack went to the forest where he thought back on his mother's words and pondered on what to think of Lucifer. The pains were, in fact, the start of intense, life-threatening pain that Kelly was going to experience since birthing a Nephilim was always fatal to the human. Once Dean returns, he explains he had the ghoul take the fall of the guard's death as Jack has an outburst regarding the dead man and is scared that he will hurt the others saying they are all he has and he can't hurt them. Jack explains that Billie's spells have been turning him into some kind of bomb and when he goes off, Chuck and Amara will cease to exist. Sam further reveals that Lucifer was the one who killed Maggie and Jack forces his father to admit the truth. In Optimism, Jack has grown tired of resting in the bunker and tells Dean that Sam is on a hunt with Charlie Bradbury while Bobby and Mary are on leave. Sam and Dean try to get more specifics out of Jack for how he will kill God when the time comes, but he clearly doesn't know. In LOTUS, after Lucifer took possession of President Jefferson Rooney, he had sex with Jefferson's aide and lover, Kelly, who was unaware of the possession. In an attempt to get free, Dean tries to break the cuffs with the archangel blade, but it instead sends Jack flying backwards into a cabinet and Dean states that the cuffs aren't coming off without the key. He identifies Michael who flings Jack aside and prepares to make him submit, Jack stands defiant and prepares for a fight.

Desperate to save Mary, Dean forces her at gunpoint to join them. While he can understand emotion and why he felt it, he still can't feel himself and can only understand why the Winchesters are angry about the death of Mary Winchester. Subduing a doctor, Jack is able to help Kaia escape through a triple-locked door.

Remember how the original Death told Dean that he’ll be there when God dies and reap him in “Two Minutes to Midnight”? To Jack's surprise, he is visited by Lucifer who reveals that Sam left him behind in Apocalypse World, but claims not to hold a grudge. However, Dean is no longer as angry as he was once was with the young Nephilim and refuses to let Mrs. Butters hurt him. Drinking beers, Jack explains that he wanted to return every day since his resurrection, but he couldn't as Jack can't use his powers without God knowing he's back and trying to kill Jack again. He then hears Dean state he was the cause of Castiel's death which causes his eyes to glow as he says the angel's name.

To all their astonishment, he is fine.

Dean later states that Jack is now powerless as a result of what happened.
