Jack's Relationships

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

Jack and Castiel
Jack 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. Castiel dutifully took care of Kelly, ignoring Sam and Dean completely either because he wsa being mind-controlled or 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 father. Jack spent his first few hours alive looking for his father. Sam eventually told him that Castiel was gone.

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

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.

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 more 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 and Sam Winchester
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".
