Sam Winchester

Samuel "Sam" Winchester is a fictional character in The CW Television Network's Supernatural played by Jared Padalecki.

Background
Sam Winchester was born on May 2, 1983 to John and Mary Winchester. Sam was the couple's second-born child and younger son, four years younger than his older brother, Dean Winchester. Sam is different from his older brother, Dean, in that he is rational, sensitive, and seemingly more concerned with living a "normal life" than his brother; in spite of this, it is apparent that he would do anything for Dean. He also rebelled against his father's attempts to raise him as a hunter and enrolled in Stanford University. When Dean came to ask Sam for his help in the first episode, the viewers are introduced to Jessica, Sam's girlfriend. It is apparent that Sam was somewhat popular, despite no one knowing what it is his family really does. His brother, Dean, is the only one allowed to call him by his nickname, Sammy. Sam has also had more love interests than Dean, although Dean has had a few flings on the show.

Season 1
Sam Winchester was born on May 2, 1983. When he was only six months old (November 2, 1983), his mother Mary was killed in his nursery by The Demon. Infant Sam was saved when his older brother, Dean, ran outside with him while their father John went back to attempt to rescue Mary, who was stuck on the ceiling and consumed by the flames that later engulfed the entire house.

Twenty two years later to the day, the same demon killed Sam's girlfriend Jessica Moore, which spurs Sam to embark on a journey to find their missing father and get vengeance on the demon. While John Winchester is missing, he occasionally contacts the boys to leave them new missions to complete. The boys fend off mystical creatures and urban legends such as the Woman in White, the wendigo, folklore's Bloody Mary, and shapeshifters. Through these missions, Sam begins experiencing episodes of precognition and once displays telekinesis.

The season finale concludes with Sam, Dean, and their father John escaping from a horrific crash with The Demon in Salvation, Iowa. While Sam is driving the Winchesters to a hospital after Dean and John were hurt, a truck crashes into them, causing massive damage to Dean's Impala with the Winchesters inside. Will They Survive?

Season 2
In the beginning of the second season, Sam takes a more active role in the hunting. He tells Dean that this is what their dad would have wanted him to do. The Demon's plans for Sam are still unknown. Dean and Sam meet with three people that John once knew: Ellen Harvelle, her daughter Jo, and their computer genius associate Ash. They assist the brothers in their hunting. In the episode "Simon Said", Sam displays immunity to Andy Gallagher's power of mind control, as opposed to Dean who gave him his beloved Impala. He is also immune to the demonic sulfur virus in the episode "Croatoan".

Since "Hunted", Sam has learned what his father told Dean moments before his death: that the Demon plans to cause Sam to become evil and use him and "children like him" as soldiers in an upcoming war. Dean was told that if he could not save Sam, he would have to kill him. Sam is convinced that he must save as many people as he can in order to change his destiny, as he drunkenly states in "Playthings".

In the episode "Born Under a Bad Sign", Sam is possessed by the same demon responsible for Meg's possession in Season 1. It is also hinted at that this is also the same demon that lead to the death Ellen's husband. It becomes clear that if the time comes for Dean to shoot his brother, Dean would not be able to do so. In this episode Sam(while still possessed) also kills another hunter.

In the episode "What Is and What Should Never Be", Sam and Dean aren't close in the alternate reality created by a djinn. Neither Sam nor Dean had ever hunted, and Jessica is Sam's fiancee. As in reverse to reality, their mother is alive, but their father is dead.

The first episode of the season finale of season two, All Hell Breaks Loose, Part 1, Sam is trapped in a haunted abandoned town in South Dakota with "Others" of his kind. It was revealed that there is demon blood in Sam and his mother Mary Winchester knew who the demon was, much to Sam's surprise. He is stabbed by a soldier named Jake and collapses in his older brother's arms just as he and fellow hunter Bobby arrive to the rescue. He dies within the minute, amongst his brother's pleas for him to stay with him. In the second episode of the season finale, Dean made a deal with a "Crossroads Demon" to deliver himself to Hell in one year, in exchange for Sam's life. Sam doesn't know of what happened while he was dead, and is in fact unaware he was ever dead in the first place. In the following battle to prevent Jake and the "Yellow-Eyed Demon" from unleashing a demonic army, Sam shoots and kills Jake, unloading seven bullets into his body - 4 in the back and 3 in Jake's face. This is the first time Sam kills a man, or someone that isn't a demon, and seems to show no remorse, this could be because of the fact that Jake killed him prior.. The "Yellow-Eyed-Demon" questions Dean if he is sure that what he brought back in Sam is 100% pure. Sam figures out that he was dead, and tells Dean he'll get him out of the deal he made, no matter what.

Season 3
Different in many ways, Sam desperately tries to find a loophole in Dean's deal. He picks up the broken Colt and with help from Bobby and the mysterious Ruby, fixes it.

In the episode, "Sin City", Dean is trapped with a lustful demon, causing Sam to come to his rescue. As a race unfolds, the demon calls forth help. Sam is well aware of this too. As the seductive demon breaks free due to help, Sam is forced to kill one of them with the refurbished Colt. As Sam is about to pull the trigger on the seductive demon, Dean pleads him to stop. Too late, Sam fires, killing her.

Now, more determined to free Dean, Sam summons the Cross-Road Demon and forces it to let Dean out of his deal. The Demon tells Sam that shes just a "sales women" and that she has a boss. At point-blank range, he kills the demons with the Colt.

Deeper into the season, Sam is pitted against Gordon Walker. A rapid confrontation turns into the death of Gordan after he's turned into a vampire. Cutting his head off, Sam feels no remorse for killing him.

In the Season Finale, Dean is down to 30 hours and Sam suggests they summon Ruby. Not trusting her, they take her knife and head for Indiana where they find out Lilith is located. After many attempts to try to kill Lilith, the brothers fail. Dean discovers Lilith is possessing Ruby and sends Hell Hounds after him. A crying Sam pleads Lilith to stop. He picks up the body of his mauled brother and cries out to him.

Season 4
After Dean's death, Sam has lost all contact with Bobby. Even still, he tries several methods on trying to bring Dean back including making a deal with the cross-road demon. Still wanting to never give up hope, he lodges in Illinois, close to where his brother is buried. After Bobby learned of Dean's escape, the two goes to visit Sam. They find him enjoying his "wild side". A confused Sam tries to attack Dean, but Bobby stops him and tells him that its really the real Dean. Now trying to find information on who helped Dean, their search leads them to the diner where they meet demons who claim they know who broke Dean out. Dean, obviously knowing its a bluff, gets up and nonchalantly leaves. Sam, however, tells Dean that they're demons and they need to die or other people will. Dean protests against this. Later, Sam returns to the same Diner to confront the demons. As he enters, he's attacked but realizes that the Demon's have had the eyes burned out. He calls forth Ruby to see if she has found anything. As the two discuss, Sam shows that his powers have developed and he's able to exorcise demons using his powers.

Powers
During the course of Supernatural, Sam has been shown to have telekinesis and precognitive abilities. However, the telekinesis has only been shown once, under extreme pressure, while the precognitive abilities are the primary. They have occurred in several episodes, manifesting before the series, and continuing throughout the series until they slayed the Yellow-Eyed Demon. Sam now claims that all of his powers are gone. However, in Season 3 he displays strength superior to that of a vampire (turned Gordon) and in the finale of Supernatural, Ruby informs Sam that his powers are not gone, they are just dormant.Lilith had tried to blast him with her powers, but Sam was unaffected. In Season 4, Sam has been developing his powers and can now force demons out of their hosts and back into hell.

Death
Through the course of the series, Sam has died once and have been resurrected by the Cross-road Demon. Dean payed the ultimate price with his soul.
