Dean and John

John and Dean Winchester have a father-son relationship, as well as a solider-Commander relationship. He raised Dean in the hunter lifestyle, as well as teaching him esstental survival skills

Background
This was built upon John raising Dean in the hunting lifestyle and teaching Dean the essental skills to survive. Not to mention John was Dean's role model. All of Dean's things (music, clothing, and car) were John's.

While John was about to go hunting, he always ran down with Dean the rules. His number one rule was to watch out for Sammy. There was one night though, that Dean stepped out to play video games, and came back with a Shtriga standing over Sam. John comes in to only to injure the creature and yells at Dean for not protecting Sam. This sets Dean's mind set for his childhood. Unlike Sam, Dean never really disliked the way John raised him and Sam. Dean is just as good as John in hunting, and goes out on hunting missions by himself. Though he does partner with John after Sam leaves for college. Then three days before Dean goes to get Sam, John goes missing.

Season 1
"This is John Winchester. I can't be reached. If it's an emergency, call my son Dean. 785-555-0179. He can help."

- John Winchester

In order to find John, Dean goes to get Sam (who he had not talked to in 2 years). Despite John's missing status, Dean still takes John's teaching with him and uses them to convince Sam to hunt while looking for John. Dean also strongly believes that John is alive and gets this confirmation when John's unavailable number is now activated with voice mail. In Home Dean calls John for help about their old house. John does show up, but not to Dean.

Though at the end of Asylum, John finally calls Dean's cell. When Dean gets the phone from Sam, John gives Dean orders. Dean being the loyal son, writes it down and does what John asks. Dean continues following John's orders after all this time. John on the other hand, is trying to protect his son by not being around due to what the nature is of John's hunt. John didn't even show himself when Dean's life hanged in the balance in Faith.

Dean and John are reunited in Shadow when Dean thinks they found the demon. John comes to their hotel room and Dean is relieved to see John again. Dean apologizes to John for accidentally lending John into a trap. John forgives Dean. But then they get attacked by a daeva, and due to Sam's intervention they manage to escape. Now out Dean realizes that he and Sam are John's weaknesses and says that John needs to go on his own. Dean doesn't want to hold John back nor see him defeated. So John and Dean separate.

In Something Wicked, John sends Dean on a mission. This mission handling something that had escaped John and had attacked Sammy on Dean's watch. It was a redemption mission for Dean, so he could correct his mistake all those years ago. Dean tells Sam that because of that mistake, John began to look at Dean differently, so in turn, Dean made sure never to make a mistake like that again. Dean can't handle John's disappointment.

They are reunited though in Dead Man's Blood when John comes to join Sam and Dean on a hunt. The hunt involving vampires and the colt. Dean is though uncomfortable when John and Sam begin arguing like in the old days. Later on in the episode, John finally reveals the truth about the colt and it can kill the demon that killed Mary Winchester. They attempt to get it back, but are foiled and forced to run. After that John sends Dean to a funeral home to get Dead Man's blood. Ready to head out, John gives out orders and heads out. This is where we first see Dean disobeying his father's orders when he comes back to save John. They all have a talk, and they decide to go hunting after this demon together.

So they head out after the demon with the colt. Then Sam gets a vision and John gets angry with Dean about not telling him. Dean responds by that getting John on the line was damn near impossible. Like when Dean called about the old house, or when Dean was near death. John gets the message and tells Dean hes right, but doesn't like the new tone Dean is using.

Seasons 4 & 5
Dean goes back to the past with help of Castiel and meets his father in a diner. There John buys Dean a coffee. Dean also advises John on his car purchase, the Impala. Its because of Dean's intervention that John buys the Impala. Then in Season 5, they meet again. Although John can't remember Dean. Dean comes to John and Mary's house under the pretense that Dean is Mary's cousin. When the truth comes out about what Dean really does, John a bit of his fatherly side and tells everyone to shut up. Though John is quick to learn from Dean. Though Michael scrubbed John's memory clean of anything about meeting Dean.
