have always had a great brotherly relationship. They are both protective of each other and will die for another.
Their relationship has changed throughout the years but they still travel and work together. This relationship also begins to develop as one of the show's main plot lines.
Background
Dean is the older to Sam and was always told from a young age to "watch out for Sammy". When the demon killed their mother, it was Dean who carried baby Sam out of the house. Dean is like Sam's protector and Dean views himself like this. So when their father John Winchester went out hunting, Dean would watch over Sam. So Dean would basically cook and protect Sam while their father was out. There was one time though when Dean left Sam alone to play some games. When Dean got back, there was a Shtriga standing over Sam. Dean pulled a gun out, but didn't shoot. Then their father showed up and got rid of the creature. He also yelled at Dean for not watching Sam. This enforced Dean's resolve to protect Sam.
Young Dean and Sam celebrating Christmas together.
As the boys get older, Sam starts asking questions about what kind of work their dad does and why they always have to move around. Dean lies to Sam and makes a remark. Dean tells Sam their Dad is a Superhero. Sam continues on by asking if its because of mom. Dean gets angry and leaves. He comes back later and gives Sam 'dinner'. Sam reveals to Dean that he found Dad's journal and asks if its true. Dean tells Sam its all true (except for Santa) and how Dad fights these monsters. Dean essentially is the one shows Sam the truth about the world and all its supernatural creatures. Realizing Dad is probably not coming home because of the job, Sam goes to bed upset. Dean feels sorry for his brother and tries to make it up to him by stealing presents from other home. Much to his luck, its all chick presents. Sam thanks Dean anyways and gives him the necklace he was going to give dad. This necklace Dean wears till Season 5.
Sam and Dean also go to high school together for one year (Dean in Gr.12, Sam in Gr.9). Dean displays his protective nature again when Sam gets picked on by a bully in Truman High. Dean threatens to tear the kid's lungs out, but Sam stops him. Dean though wonders why Sam didn't take this guy out (due to their combat training). Sam doesn't want to be the weird kid again, which appears to confuse Dean.
A year later, Sam is left alone when Dean and John go after a kitsune together. Sam helps gather information for them, and often talks to Dean on the phone. Sam later asks Dean for advice on how to talk to girls, and trys it when he attempts to talk to Amy Pond. Sometime after that, they continue hunting till Sam wants to go to college. Sam leaves and doesn't talk to Dean for 2 years.
Season 1
| “ | I swore I was done hunting for good. Come on, it wasn't easy, but it wasn't that bad. Yeah? When I told Dad I was scared of the thing in my closet, he gave me a .45. Well, what was he supposed to do? I was nine years old. He was supposed to say, "Don't be afraid of the dark." Don't be afraid of the dark? What, are you kidding me? Of course you should be afraid of the dark! You know what's out there! | ” |

Later, Sam and Dean discover there is a book series about them about there called "Supernatural". Not only that, but Sam/Dean fan-fictions, which Dean expresses his disgust at. They meet the author and he later tells them Lilith is coming for Sam. Dean is shocked at this and tries everything to make sure it doesn't happen. Sam on the other hand, wants Lilith to come so he can kill her.
Everything changes when Dean finds out that Sam has been drinking demon blood. Dean locks Sam away so he can detox. Sam begs Dean to let him out and tries to explain why he was drinking the blood.

Sam sees Brady and gets angry, but Dean holds him back. Sam manages to lock Dean in the washroom and confronts Brady. Sam realizes Brady isn't worth it and lets Dean out. The real trouble comes when Sam suggest that he says yes to Lucifer and jumps in the hole in Two Minutes to Midnight. Dean doesn't like this idea one bit, but Sam believes this to be the only way to defeat the devil.
As Dean promised to Death, he agrees to let Sam jump in the hole. On the way there, Sam makes Dean promise not to bring him back and to go to Lisa once this is done. Basically live an "apple pie" life. Dean doesn't agree at first, but in the end, he does. When Sam has to drink the Demon blood, he asks Dean to turn away, because he doesn't want Dean to see this.

Though Dean begins to notice changes in Sam. Like when Sam held him back when Castiel soul probed a young kid. Dean expresses this concern to Bobby in Weekend At Bobby's. This confusion deepens further when Sam appears to let Dean get turned into a Vampire. As a vampire, Dean notices Sam unusually calm, but Sam tells Dean is trying to keep calm in this situation. Once cleaning out the nest and getting cured, Dean gets a flashback where he noticed Sam watching him getting turned.
In You Can't Handle the Truth Dean gets a truth curse cast upon him and he attempts to use it on Sam about what happened when he was turned into a vampire. Sam tells Dean that what he thinks happened didn't. But the encounter with Veritas confirms Dean suspicions. Sam tells Dean he did let Dead get turned because he knew they had a cure and so they could find the alpha vampire. Sam tells Dean there is something wrong with him. Dean is silent and then breaks out with a punch. Dean beats Sam unconscious.
Dean enlists Castiel to help figure out whats wrong with Sam. Castiel asks Sam a bunch of questions and Sam answers. Sam can't believe Dean is having Castiel treat him. Castiel soul probes Sam and finds that Sam is missing his soul. This explains Sam's actions to Dean, and Dean asks when Sam is still even "Sam". In the end though, Sam still chooses Dean over Samuel. So they follow Samuel to a compound where they take all the captured creatures. There they meet Crowley who claims to be the one who brought Sam back, and forces the boys to work for him. Dean doesn't like the idea, but Sam promises Crowley will get whats coming to him.
Dean now knows Sam is soulless, and tries to deal with this fact. In All Dogs Go To Heaven, Dean tells Sam to stop trying to be "Sam". Mostly because this soulless version could never be the real one. In the end of the episode, Sam tells Dean the truth about how he really feels. He tells pretty tells Dean he doesn't care about anything, including Dean, but he needs Dean's help.

But Dean doesn't give up. In Appointment In Samarra Dean makes a deal with Death for Sam's soul. Sam still doesn't want his soul tries to look for the rings, but Dean already has it. Sam lies to Dean saying hes fine with getting his soul back, when in reality, Sam doesn't want it back. Dean becomes Death for Sam, but loses the wager.

While waiting Dean is worried Sam will never wake up, but as Bobby and Dean are talking about a hunt, Sam appears and hugs Dean. At last, the real Sam is back. Which Dean is more than grateful for. He expresses this when he and Sam are on a hunt for Dragons in Like A Virgin. Sam though is made aware of what happened when he was soulless(thanks to Castiel) and he apologizes to Dean. Dean tells Sam it not his fault, but Sam disagrees.
Sam continues to investigate what happened during the time he was soulless and Dean does not want Sam to dig any deeper. He is afraid the wall in Sam's mind will break. In Unforgiven Sam passes out and sees a moment of hell. Sam's passing out frightens Dean and he has no idea of what to do. Sam does wake up and Dean takes him out. Dean later asks if Sam wants to talk about it and believes what Sam saw was hell. Dean tells Sam to just forget about it and don't kick the wall. Sam doesn't want to forget about it but leaves it alone. Sam and Dean continue to hunt without Sam kicking the "wall". Although Sam does thank Dean for getting his soul back, which Dean is thankful to hear.

Dean stays beside Sam's bedside while waiting for him to wake up. Sam begins to move, Dean gets really concerned. When Bobby makes Dean go back to work, Dean stays by Sam's side until he can't. While leaving Dean leaves Sam the address of where they'll be. Meanwhile in Sam's head, it he has to choose between not remembering everything and forever stay in a coma. Or, remember everything and help Dean. When Sam does wake up, he heads to Dean's location while he still is messed up. In order to save Dean from Castiel, Sam stabs Cas only to find out it doesn't work.
