Jack's Relationships

This is all of Jack's relationships from throughout the series.

Jack and Castiel
"Jack, your mother, she believed that you would do amazing things, she said that you would change the world for the better. And now, looking at you, talking to you, I know she was right. That we were right. Kelly would be so proud of you."

- Castiel to Jack

Initially, Castiel had saw the unborn Jack as a potential danger to the world and attempted to kill him and his mother Kelly Kline out of fear of what would occur if he was born. Castiel later saw a new view of the child and desired to protect him from danger such as with Lucifer and Dagon.

After his birth, Jack told Sam he had chosen Castiel, since the time he was in his mother's womb, to be his protector. He favored the angel over Dagon and used the promise of a utopia as a means to convince the angel to stay by his mother's side. Jack empowered Castiel to kill the demon and Castiel dutifully took care of Kelly, ignoring Sam and Dean completely either because he genuinely felt attached to his new ward.

By the time Jack was born, Castiel had been killed by Jack's biological father Lucifer. Jack recalled very little of his time in the womb and claimed that it was his mother who told him that Castiel was the one who would protect him and keep Jack safe like a father. Jack spent his first few hours alive looking for Castiel as a result. Eventually, Sam told him that Castiel was gone which saddened him.

Jack returned to his mother's cabin and witnessed a hunter's funeral being performed on his mother and "father".

Jack soon learned that Castiel was not his father but his uncle and that Dean's dislike in him comes mostly from the fact that Jack indirectly caused Castiel's death. When Sam and Dean argue over their opinion of Jack, Jack sadly calls out to Castiel and in doing so awakens Castiel in The Empty. Much later, Castiel demanded the Cosmic Entity release him from the realm and he was soon resurrected.

In Tombstone, the Winchesters bring a resurrected Castiel to the bunker and he meets Jack who is shocked to see him alive. Jack also learns that he played a partial role in bringing him back since it was his pleading that awoke him. Jack hugs Castiel, extremely happy to finally meet him and shows what he has learned from his time with the Winchesters. While working on an assignment, Jack and Castiel catch up with Castiel apologizing for not being there when he needed him but the latter assured him it was alright as he understood it wasn't by choice. Castiel tried to comfort Jack after the latter accidentally killed an innocent but Jack instead left the group.

During War of the Worlds, Castiel searched for Jack even seeking aid from the angels. When the angels propose Castiel helped locate Jack and help him rebuild their numbers, Castiel immediately refused as he didn't want to enslave Jack to that pain. Castiel also refused to let Lucifer (who returned from the other world) near Jack even after hearing that the Alternate Michael intends to invade.

In The Bad Place, Jack states that he only sees Castiel and the Winchesters as his family instead of Lucifer or the angels.

In Devil's Bargain, Castiel brought up his promise to Kelly Kline that he'd protect her son. To that end, Castiel was ready to go back to the Apocalypse World and save Jack from Michael.

During Good Intentions, Zachariah tried to manipulate Jack by playing a scenario of Castiel who Jack was happy to see though was worried as the latter told him not to trust humans. Jack soon realized the truth of the illusion as he knew Castiel wouldn't say such things about humans. Castiel would work on gathering the ingredient for the spell to open the rift and resort to ripping them from Donatello Redfield's mind, after listing Jack as one of the people he loves.

In Bring 'em Back Alive, Castiel asked Dean where Jack and Mary were and was relieved that Michael doesn't have them.

In Beat the Devil, Castiel and the others open a rift and travel through Apocalypse World.

After finding Mary who takes them to a camp, Castiel reunites with Jack. When Jack becomes distraught at Sam's fate and asks why they didn't revive him, Castiel tells his nephew that they aren't strong enough to resurrect Sam. Castiel then tried to comfort him but the latter turns him away before Sam arrives alive but with Lucifer.

During Exodus, Castiel becomes worried after Jack decides to talk with him and tries to discourage him but to no avail.

In Let the Good Times Roll, Jack and Castiel aid the Winchesters in hunting monsters. Following the death of Maggie, Castiel pursue Jack to a gas station, where he helps Sam and Dean in stopping him from hurting an innocent employee and he leaves shocked that he hurt someone again. Castiel was later worried to hear Lucifer returned and had Jack.

Jack and Dean Winchester
Dean views Jack as a dangerous being and blames him for the loss of Castiel, as Jack had been the one to convince Castiel to watch over his pregnant mother and leave Sam and Dean behind. Dean spent the months leading up to Jack's birth feeling upset and angry and viewed Castiel's running away with Kelly as the angel being manipulated.

When Jack was finally born, Dean's first response was to shoot him, only for Jack to unleash his powers in self-defense and knock Sam and Dean out. Dean's opinion on Jack didn't improve as he began hunting for the Nephilim. His distrust in Jack contrasts Sam's softer opinion, likely due to Dean's grief caused by losing Castiel again.

Dean does however, give Jack's mother a hunter's funeral alongside Castiel.

Jack soon learns that Dean still doesn't like him and makes a clear effort to emulate Dean in order to appear more likable. Dean is both annoyed and distrustful of Jack. Dean eventually admits to Jack that should Jack go dark side as Dean anticipates, he'll kill Jack himself. Jack overhears an argument between Dean and Sam in which he learns of Dean's negative feeling stem from him blaming Jack for the death of Castiel. In turn, Jack sometimes believes he is evil because of Dean's words, but Sam does his best to cheer Jack up.

"He manipulated him. He made him promises, said paradise on Earth, and Cass bought it and you know what it got him? It got him dead. Now you may be able to forget about that, but I can't!"

- Dean Winchester's initial opinion on Jack

Jack continues to long for Dean's approval while Dean chooses not to baby him and make him do some of the work during cases, or in Sam's words, treat him like an intern. When Jack becomes dismayed by the lack of approval from the elder Winchester and keeps thinking about Dean's promise to kill him, Sam informs Jack that he can earn Dean's approval through effort, something Dean respects.

While confronting the shapeshifter Buddy, Dean and Jack are both chained up though Dean orders Jack to use his powers to free them. Jack, afraid his lack of control over his own powers may hurt Dean, refuses to obey the order. Jack instead uses his powers to prevent Buddy from shooting at Sam, which gives Sam the opportunity to shoot Buddy, thus solving the case they were working on.

Afterwards, Dean praises Jack for his efforts and acknowledges that he finally did good as Jack smiled to himself at this praise.

With Castiel's resurrection and return, it appeared Dean gave up some of his disdain for Jack since he had partial role in it and he listed Jack as a member of the team. Dean even counted him as a member of Team Free Will and humored Jack on a hunter case but was ready to go along with as it allowed him to act like a cowboy. He was also surprised that Jack was right about it being a case though the monster was something else. Jack wanted to be useful and tried to help Dean by using his powers though unintentionally killed an innocent. Rather than scold Jack, Dean instead told Sam and Castiel to take him back to the Bunker while he deals with the threat. After completing the case, Dean even covered for Jack by putting the innocent's death on the monster. Jack was shown not to accept this and broke down that he might actually be evil but Dean said he wasn't as he admitted that he was wrong in thinking he was.

"Jack: I was scared, I was upset, but why would I look for him? He's no one to me. You, Castiel, you're my family.

Dean: Yes, we are."

- Jack and Dean Winchester

After learning that Jack apparently killed Derek Swan, Dean discussed killing him for it with Sam. However, Dean admitted that he actually liked Jack and saw it as a worst-case scenario that he must be killed. Once they found him, they confronted Jack over his action but he was revealed to be innocent and told them his true intention were to find their mother, which he was able to do letting them know their mother is still alive. When Jack called the Winchesters and Castiel his family, Dean instantly agreed that Jack was family. Dean then praised Jack's initiative in trying to rescue Mary as the latter smiled at his words. Dean continued to be this way when Jack refused to join the angels and wanted to stay with them instead.

During Devil's Bargain, Dean and Sam are told by Castiel that Michael of that world and he intends to invade. Dean realized Jack and his mother are in danger and they decide to capture Lucifer and open a rift to enter the Apocalypse World to save the pair. Dean shows he still sees Jack as part of the family.

In Good Intentions, Jack chooses to help defend Bobby Singer's colony from Zachariah and his angels because he knows its what Sam and Dean would do. He also knows that Sam and Dean would stay and fight and chooses to kill Michael to protect the people of Apocalypse World.

In Beat the Devil, Dean and the others open a rift and travel through Apocalypse World.

After finding Mary who takes them to a camp, Dean reunites with Jack and both witness Sam's return as well as the arrival of Lucifer.

In Exodus, Dean told Jack to not approach Lucifer as he didn't want Jack to turn evil.

During Let the Good Times Roll, Jack had a nightmare but Dean came in his room to comfort him on this and told him they were family. Jack went on more cases with Dean and the others. The bunker was attacked by Michael and Jack was alerted of this by Sam's prayer. He arrived in time to save Dean from nearly being strangled to death by Michael and almost acted on his promise to kill the Archangel but was prevented when Michael revealed his deal with Lucifer. Jack was later horrified to watch Michael take full control over Dean after he managed to kill Lucifer.

Jack and Kelly Kline
Jack's mother.

Kelly had wanted to start her own family for some time and viewed President Jefferson Rooney, her lover, as the perfect man to be the father. Unfortunately for her, Jeff had been possessed by Lucifer and when Kelly conceived, it was Lucifer's child in her womb. Kelly was told of this by Sam and Dean, but the knowledge did not make her despise the child growing inside her, as she was still the child's mother. She evaded the Winchesters in hopes of keeping the baby safe.

When angels began attacking her, Kelly decided to rely on Dagon as a protector to ensure her baby's survival. She also learned from Dagon that the baby was a boy. Kelly was always concerned for her son's well being and could become frantic when things didn't feel right, such as the "weird little pains" she began experiencing a few months into her pregnancy. When she demanded to have her son looked at, Dagon took her to a clinic where Kelly was able to see her son on a monitor.

This would be the only time mother and son would see each other, as Kelly came to learn from Dagon that birthing half-angels was always fatal to the mothers. This piece of information deeply upset Kelly, and as Dagon's treatment of her worsened, Kelly came to doubt her son's future and felt he might be born as a bringer of destruction. She tried to commit suicide to prevent this possible scenario, but her son responded by resurrecting her and letting her know that he was not evil.

Kelly's love for her son returned, so much that she came to believe her son could save the world. She was able to convince Castiel of these beliefs. When her son began sending her visions from the womb, Kelly chose to trust her son and allowed him to guide her. She accepted Castiel as her son's new protector in place of Dagon. At her new home, Kelly decided to name her son "Jack" and left him a video telling him how much she loved him.

"I love you."

- Kelly's last words

Kelly's belief that the world was dangerous and Castiel would be the one to protect Jack drove the newborn baby to grow into adulthood and seek out his father, whom he thought was Castiel, not Lucifer. After realizing Castiel was dead, Jack returned to Kelly's cabin and mourned her death, showing grief for her. As Sam and Dean prepared a funeral for Kelly and Castiel, Jack was at a loss of words for what to say. Kelly's own last words to Jack were, "I love you".

As Jack struggled to control his powers and dealt with Dean's rejection of him, he came to doubt his own purpose and saw that he might be truly evil. Sam reassured him that he and Kelly believed there was hope for him. Sam later revealed the existence of Kelly's video made for Jack on the day Jack was born. Jack watched it with a sad expression on his face. When Sam and Dean took Jack to a grief counselor as part of a case, Jack decided to ask the grief counselor, Mia Vallens, to help him speak with his mother. Mia agreed and shapeshifted into Kelly's form. Jack spoke with "Kelly" who told him that what he was didn't matter, it's what he did. She encouraged him to believe that even monsters can do good in this world.

Jack and Mary Winchester
Jack had heard Sam and Dean mention her several times. He knows that Dean blames him for Mary's fate while Sam wants him to open a rift to save her from the world.

In The Bad Place, after leaving the Winchesters, Jack was revealed to have mastered his powers to feel other worlds and to prove he is good by locating and rescuing Mary Winchester for Sam and Dean, since he knew they missed her. He tracked down Derek Swan, a dreamwalker who was able to find Mary but Derek wasn't strong enough to hold the connection long enough for Jack to open a rift. Jack stops before he can seriously hurt Derek and Derek points Jack to Kaia Nieves who is the most powerful dreamwalker Derek has ever met. After being found by Sam and Dean, he tells them his real goal was to get their mother back and shows them the vision Derek saw of her. Dean later congratulates Jack on finding his mother which Jack accepted with a smile. At the end, Jack arrives alone in the Apocalypse World and wakes up at the feet of Mary who is trapped in a small metal cage. As Mary stares at Jack in confusion, Jack looks at Mary's predicament with worry.

During Good Intentions, Jack got properly acquainted with Mary as Michael held them captive. The two soon broke out and were found by Bobby Singer who took them to his camp. Mary was seen smiling as Jack bonded with the people there but after Bobby distrusted him for his heritage and wanted him to leave, she decided to go with him. When the camp came under attack, Mary implored Jack to run and he complied but turned back as he knew her sons wouldn't run. His decision was a good choice, as Jack saved Mary from being killed by Zachariah.

It was mentioned Bring 'em Back Alive, that he and Mary have become leaders of a human resistance against Michael.

In Unfinished Business, Mary is shown to have taken on a motherly role towards Jack. When discussing Jack going after Michael, Mary makes it clear that she now sees Jack as part of her family as she states that she can't lose "another one of my boys". Jack is deeply touched by her words and hugs her. When Kevin Tran attacks, Jack shields Mary, saving her life and cradles her unconscious form afterwards. Jack and Mary then talk and she consoles him as they look upon the bodies.

In Exodus, in contrast to Sam, Dean and Castiel, Mary had no problem with Jack interacting with Lucifer, believing that Jack was bound to take an interest in him. Though unlike the Winchesters and Castiel she wasn't worried about the idea of Lucifer causing Jack go dark side, as she was confident that Jack would eventually see Lucifer's true nature.

Jack and Sam Winchester
"Jack: Maybe I'm not worth all this. Sam: Your mom thought you were. So did Cass. So do I."

- Sam Winchester and Jack Sam is the first person Jack encountered after he was born. When they first laid eyes on each other, Jack was mostly obscured by shadows in the corner of his nursery, and he gave Sam a creepy smile, frightening the hunter.

Jack initially mistook Sam for his father and Sam had to correct him. To avoid conflict, Sam tried to speak calmly with Jack to let Jack know he didn't mean the newborn any harm. Sam's plans were torn apart when Dean decided to shoot at Jack.

Jack fled and the brothers pursued him. Sam believed Jack was not an evil child and he sought to have a proper conversation with him. Once the brothers found him at the Sheriff's office, Sam stunned Jack with a taser after which the two ended up in the holding cell. Sam was terrified of Jack once more until Jack reassured him that he wasn't using his powers on purpose.

The two began to converse and Jack announced his desire to find his father, so his father could protect him as his mother promised. Sam told Jack that his father - meaning Lucifer - didn't do that but Jack corrected him, saying he meant Castiel. The two soon got into a fight with angels who had come to claim Jack. When one angel tried to kill Jack, Sam was forced to kill her, only to remove the angel blade from his chest unharmed.

Jack joined Sam and Dean in burning the bodies of his mother and "father". Jack didn't know what to do say, so Sam suggested saying "sorry" and "thank you".

In contrast to Dean, Sam supports and believes in Jack becoming a good kid who simply needs to learn how to use his powers. Sam makes an effort to help Jack in this regard and also remind him that Jack is not evil. Sam however, does seek to use Jack's power in hopes of freeing his mother from the alternate universe. When Jack confronts him on this, Sam admits to this when he is questioned by him. Sam tells Jack that he won't force him to try and continues to encourage Jack to believe in himself. Sam also stated he won't let Dean hurt him after hearing the latter swore to kill Jack. Jack overheard an argument the brothers and heard Sam defending him after Dean accused him of manipulating Castiel.

During The Big Empty, a case involving a shapeshifter came up and Sam invites Jack on the case to see what they go through. Jack also saves Sam's life by stopping a bullet fired by the shapeshifter Buddy from hitting Sam. Because of this, Sam's faith in Jack slowly grew even further.

In Tombstone, Sam quickly deduced Jack was responsible for bringing Castiel back. Sam was proud that Jack's powers did good as they brought back an old friend and moved Dean out of his depression. Sam humored Jack in his supposed hunter case however, he saw Jack was right about it being a supernatural creature. When Jack tried to help Dean in fighting off a ghoul, Sam and Cass warned him but to no avail as he used his powers and killed an innocent as well. Jack was horrified as Sam tried to reassure him but he couldn't get through. On the way back, Sam tried to console Jack after his accidental killing but the latter angrily tells them to stop. This act caused Jack to leave the group out of fear of hurting them.

In The Bad Place, Sam is reluctant to believe that Jack killed Derek Swan and that he must be killed. After finding Jack who is determined to be innocent, he reveals he was using his powers to search for their mother and has located her, letting Sam and Dean realize she was still alive. On the drive, Jack states that he only sees the Winchesters and Castiel as his family while Lucifer and the angels are nothing to him. Sam is visibly pleased by this and the fact that Dean instantly agrees that Jack is their family. At the end, they are sent to separate realities.

In Wayward Sisters, Sam questioned Kaia Nieves of Jack's whereabouts and is told that he is with Mary Winchester in Apocalypse World, to Sam's worry.

In Breakdown, Sam enters a depressive state at Jack being gone as he and Dean have lost another important person, as well as hope for finding their mother.

During Devil's Bargain, Sam and Dean are told by Castiel that Michael is the that world and he intends to invade. They realized Jack and their mother are in danger and they decide to capture Lucifer and open a rift to enter the Apocalypse World to save the pair.

In Good Intentions, Jack takes the lessons Sam and Dean have taught him to heart by returning to defend Bobby Singer's colony as he knew that its what they would do instead of running. Similar to what he knows Sam and Dean would do, Jack decides to kill Michael in order to save Apocalypse World.

In Beat the Devil, Sam and the others open a rift and travel through Apocalypse World.

Sam was happy to be on the journey to save Jack but he was attacked by a nest of vampires who devoured him.

After the others tell him of what happened to Sam, Jack becomes distraught at learning Sam's fate and asks why Gabriel or Castiel didn't revive him. Jack was then happy as Sam arrived to the camp alive and smiled at Jack before Lucifer arrived as well.

During Let the Good Times Roll, Jack went on more cases with Sam and the others. The bunker was attacked by Michael and Sam prayed to Jack for help. Alerted by Sam's prayer, Jack arrived in time to save them from death by Michael and almost acted on his promise to kill the Archangel but was prevented when Michael revealed his deal with Lucifer. Lucifer took Jack's power and was about to leave with him before Sam grabbed onto Jack, taking him as well. Jack was horrified to watch Lucifer attack Sam and even more so when Sam told Jack to kill him after Lucifer pitted them against each other. Sam was distraught to nearly watch Jack commit suicide before Dean arrived and using Michael's powers, killed Lucifer.

Jack and Gabriel
Gabriel was Jack's paternal uncle. They didn't know about each other for a while though Sam and Castiel informed Gabriel about his nephew and his whereabouts in Bring 'em Back Alive. Gabriel had to process this knowledge for a while though wanted no part in the conflict.

In Unfinished Business, after the Winchesters helped him Gabriel decided to offer them aid in the conflict.

During Beat the Devil, Gabriel and Jack met face to face in the resistance's camp. Gabriel told a distraught Jack who learned of Sam's fate that he wasn't strong enough to resurrect the latter before he appeared with Lucifer.

In Exodus, while Lucifer is talking to the others and Jack leaves upset, Gabriel goes after him before Jack returns. When Lucifer was telling Jack about his family, he points him out to his uncle though Jack pointed out they met. The two greeted each other as Gabriel told his nephew not to trust what his father is saying since he merely plays the victim and Jack is seen pondering on his words.

Gabriel sacrificed himself to save Jack and the humans by fighting Michael. It is unknown what Jack's reaction was to Gabriel's death or what he thought of him since he wasn't a hostile angel like the others he met.

Jack and Bobby Singer
In Good Intentions, after escaping from Michael's fortress alongside Mary Winchester, Jack befriends the Apocalypse World version of Bobby Singer. While Bobby initially likes Jack, taking Mary at her word that he's a "friend of the family" which is good enough for Bobby, Bobby's opinion changes once he discovers Jack is a Nephilim. Due to his own encounters with angels, Bobby shows a belief that Jack will turn on the humans and that its only a matter of time, effectively exiling Jack and angrily rejecting his help against Zachariah and his men.

After he witnesses Jack kill Zachariah and three other angels to save his colony and Mary, Bobby changed his opinion of Jack and thanks him for his help, showing no further desire to get rid of Jack. Bobby listens as Jack and Mary discuss Jack's reasoning and is surprised to learn that Jack intends to kill Michael to protect them.

Jack and the people of Apocalypse World
In Good Intentions, after escaping from Michael's fortress alongside Mary Winchester, Jack is taken to Bobby Singer's colony where he is saddened to see the injured state of the people and to learn that they are being targeted for extermination. During the night, Jack uses his powers to amuse the young children of the camp in an act of kindness to brighten up their dark lives. Jack admits to Mary that he admires the people he's met on Apocalypse World and their bravery and wishes to stay in the colony. When Jack is told that he can't stay, he's confused and saddened.

When Zachariah and his angels attack the colony, Jack chooses to defend the people instead of running and hiding as he knows its what Sam and Dean would do. After killing Zachariah and three other angels, Jack gains acceptance once more despite being a Nephilim and decides that to protect the people he has come to care for from the angels war of extermination, he has to kill Michael.

It was mentioned Bring 'em Back Alive, that Jack has formed a resistance of humans to stand against Michael, which means he is well respected.

In Unfinished Business, Jack is treated with a lot of respect by his resistance fighters and is greatly pleased by the number of people he is able to save from Michael's armies. After Kevin Tran kills three resistance fighters on orders from Michael in order to break Jack, Jack is devastated by their loss as he had promised to protect them and cared about them.

Jack and Clark Barker
In Lost & Found, shortly after his birth, Jack met and befriended teenager Clark Barker who treated him with kindness and was fascinated with Jack's powers. Clark was the first to introduce Jack to some human things which he greatly enjoyed.

Jack and Dagon
Dagon aspired to be Lucifer's Queen and Jack's mother. To this end, she took care of Kelly Kline during her pregnancy. Dagon initially treated Kelly with a degree of hospitality and did her best to prevent Kelly from being found and kept anyone - such as Dr. Turner - from realizing the uniqueness of Jack.

Dagon began mistreating Kelly after Kelly allowed herself to be lured away by Dean Winchester. Kelly's days spent with Dagon became difficult and stressful, until Jack reassured Kelly that her suffering was not for naught. Dagon lost sight of Kelly again when angels led by Castiel raided her hideout and took Kelly away. In fear of Lucifer's wrath, Dagon sought out Castiel's destination by torturing Kelvin.

She arrived in time to stop Joshua from killing Kelly and her unborn child. As Dagon proceeded to beat up Castiel, Jack gave Castiel some of his powers so Castiel could incinerate Dagon. Dagon's dreams of being Jack's mother were burnt away by Jack himself.

After being born, Jack showed little remorse for helping Castiel kill Dagon and even called her "a bad woman". Dagon is the first being killed because of Jack.

Jack and Asmodeus
Asmodeus sought to make Jack the Ruler of Hell and serve as his advisor. They first met when Asmodeus disguised himself as Donatello Redfield to get Jack to release the Shedim, but his efforts were exposed by the Winchesters and the real Donatello. Jack realized the demon tricked him as Asmodeus tries to implore Jack to join him though he attacked Jack's friends which enraged the latter. Not wanting to fight an angry Nephilim, Asmodeus was forced to escape which released the brothers. When Jack left the brothers and Castiel, Asmodeus sought to find him still intent to use him to fulfill his plans but couldn't locate him. After Lucifer returned and was captured, Asmodeus decided to increase his efforts to procure Jack when learning of an impending threat.

Asmodeus soon found out Jack was sent to an alternate reality but couldn't risk letting the threat in the world into his own.

In Exodus, Jack was made aware Asmodeus is dead, after being killed by his uncle Gabriel in the talk with the latter and Lucifer.

Jack and the Angels
"I am home."

- Jack refusing to go with the angels

Being Lucifer's son and a very powerful Nephilim, Jack was initially considered a great threat to the safety of all those around him, including Heaven who, like everyone else, feared what would occur after his birth. Before his birth, the angels main goal was to get rid of him to ensure their survival and to that end, sought to kill his mother Kelly Kline to prevent her son from being born but she was protected by the efforts of the Winchesters and Castiel.

After his birth, the angels no longer view Jack as a threat, but as a necessity to the survival of their race as after Fall of the Angels their numbers have been greatly diminished and their race is going extinct. The angels pursue Jack as they believe he has the power to produce new angels therefore, replenishing their numbers. To that end the angel Duma sought out Castiel in War of the Worlds to get him to convince Jack to help the angeld but he refused to let them near his ward. Castiel also learns from duma that the angels plan to use Jack whether he wants to or not. She even goes so far as to say jack "belongs to all of us". In The Bad Place, the angels kidnap Kaia Nieves, a dreamwalker Jack had met so they could convince him. Once Jack and the Winchesters found them, the angels try to get Jack to come to Heaven with them to be with his family. When Jack refused, the angels attempted to kill the Winchesters and take Jack only to be killed by him instead.

Similar to Lucifer, Jack does not see them as family and denounces the angels as killers, even killing one that was attacking Dean.

It was later revealed that due to Jack's unwillingness to cooperate with the angels, there are now less than a dozen angels left alive.

It is unknown what Jack thinks of the angels who are kind to humanity like Castiel.

Jack and the Angels of Apocalypse World
Much like the angels in his world, Jack is considered to being abomination by the angels of this world. They refer to him as a "half-breed" but view him as a necessity to invade the prime world by creating a rift. Zachariah tried to manipulate Jack by making various scenarios in his mind but Jack saw through them. Having awoke, he came face to face with Michael who he fought but was overpowered and thrown in a cell with Mary.

Like the angels of his world, Jack refuses to comply with their demands and help them kill humans. As such he broke out with Mary, with the angels hunting him down to the human colony. Jack was horrified at their deeds to the other world and soon killed Zachariah for trying to kill Mary as well as killing other invading angels. Jack's actions gained him praise from the human colony. Having grown to genuinely care for the people in Apocalypse World, he wanted to ensure their complete safety from the angels by killing the Archangel Michael.

It was mentioned Bring 'em Back Alive, that Jack has formed a resistance of humans to stand against Michael, which means he is actively fighting against the latter.

In Unfinished Business, Jack is shown to be actively killing angels such as Balthazar to protect the people of Apocalypse World and shows no remorse for doing so. Instead, Jack is pleased by the humans he saves by winning each battle.

During Exodus, Jack wanted to finally defeat angels by using both his father, uncle, and soldiers but was repeatedly told not to since Sam and Dean who had a plan. Jack killed many angels in the rescue of Arthur and Charlie. Before returning to his world, Jack wanted to kill Michael but Lucifer talked him out of since his plan was dangerous and he conceded.

In Let the Good Times Roll, when the bunker came under attack, Sam prayed to Jack for help against Michael who made it to their world. Jack appeared in time to save dean from being strangled to death by Michael and brutally attacked the latter, showing how much jack had grown to despise michael. He nearly acted on his promise to kill the Archangel but was prevented when Michael revealed his deal with Lucifer. Jack was later horrified to watch Michael take full control over Dean after he managed to kill Lucifer.
