Around the time of the Black Plague in 1350, Ruby was a witch who sold her soul to the demon that would later possess Tammi. Ruby became a demon herself after prolonged torture in Hell. She owns a special knife that can destroy demons, although it also kills their human host (or meatsuit). Following Azazel's death, Ruby proves instrumental in releasing Lucifer from his Cage by manipulating Sam Winchester.
She initially presents herself as an ally to the Winchesters, helping them fight demons and witches, fixing the Colt and particularly by intimating to Sam that she can help break the deal Dean made with the crossroads demon with his life. She later reveals to Dean that she can't save him, but claims to want to help prepare Sam to fight the demons after Dean is dead, claiming she remembers what it is to be human and wants to fight on the side humanity. As Dean's deal is due and they try to kill Lilith, she sends Ruby back to Hell.
While Dean is in Hell, Ruby returns to Sam. Distraught with grief, he refuses to speak to her while she is possessing someone. She finds a woman in a hospital and possesses her as she is declared dead. At Sam's lowest point she seduces him.
I referenced Monster's Ball right in the script. We were asking ourselves, "Where's the lowest place Sam can go in a state of despair?" That's why calling it a love scene strikes me as hilarious. It's kind of like self-mutilating and calling it getting dressed for the prom.
Ruby convinces Sam that she can help him develop his powers so he can kill Lilith and avenge Dean's death. She gets him to practice with his powers, and also gets him drinking her blood in order to enhance his powers.
After Dean's return, Sam keeps his relationship with Ruby a secret - continuing to drink her blood and develop his powers so he can kill Lilith, who is breaking the 66 Seals that are keeping Lucifer captive. Driven by a desire to prove himself capable to both Dean and himself, Sam fails to realize Ruby is using him, and rejects Dean's advice not to trust her.
When Sam finally kills Lilith, Ruby reveals that Lilith's death is the final seal, the one which will free Lucifer. She taunts him that it was not the demon's blood that has driven him down this path, but his own decisions. As Lucifer rises, Dean arrives, and kills Ruby with her own knife while Sam holds her in place from behind, a move that seems to hurt her.
Ruby first appears following Sam and Bobby as they track down the Seven Deadly Sins. While Bobby and Dean are fighting off Sloth and Lust, the others, led by Pride, go after Sam. The group is then joined by Ruby who gets in on the the fight and attacks the demons with a knife; the knife appears to be able to kill demons. Ruby kills two demons while Sam helps her kill a third. Ruby reveals to Sam that she knows who he is. She then disappears.
Ruby meets with Sam unexpectedly as he researches ways to save Dean's soul. She claims she is a hunter and talks with Sam about his past and his destiny; this sets Sam on a path to research more about his mother, Mary Winchester. Disturbed to find out all of his mother's friends are dead, Sam demands to know exactly who Ruby is. Ruby reveals that she is a demon and claims that Sam fascinates her. Ruby tells Sam that she is in the pursuit of knowledge for her own ends and is "on his side." The episode ends with her offering Sam a deal - he works with her to find out more about his destiny and she helps him save Dean's soul from the crossroads demon.
Sam tells Dean about his encounter with Ruby, although not about the information she gave him about the deaths of Mary's friends. Dean is angry that Sam didn't kill the demon, while Sam insists that they can use her to get information about the demons they are battling and Dean's deal with the crossroads demon.
Ruby comes to Bobby while he is working on the Colt. Bobby shoots her with it, but with no effect. Ruby offers to help Bobby make it work, and they succeed - Bobby brings the Colt to a hunt Dean and Sam] are on and Sam kills two demons with it. Later, Ruby and Sam argue - Ruby threatens to take the Colt from Sam and give it to someone else who'll use it; Sam threatens Ruby with the Colt. They come to a truce again when Ruby reminds Sam that if he kills her, she can't help him save Dean's soul. She refers to herself as "the little fallen angel" on Sam's shoulder.
When Sam threatens the crossroads demon with the Colt, the crossroads demon realizes that Ruby must have fixed it and comments disparagingly on the problems Ruby is causing her, before telling Sam, "She'll get what's coming to her, you can count on it."
Ruby appears to warn Sam and Dean away from the town where they are investigating a coven of witches. She tells them a demon is present that will come after Sam. Dean tries to shoot her with the Colt, but Sam intervenes. When Dean is attacked by a force that causes him to bled internally, Ruby saves him with a witch's potion. When Tammi is about to kill Sam and Dean, Ruby appears and at first acts as if she is on Tammi's side, but then tries to kill Tammi with her knife. Tammi reveals Ruby was once a witch who sold her soul to her. After Dean manages to kill Tammi with Ruby's knife, she tells him all demons were originally human, but during their time in hell they lose all trace of their humanity, but she has retained some of hers and wants to help humans. Ruby reveals to Dean that she can't save him from hell, but that she needs his help to prepare Sam to fight the demons after he is gone.
While the boys are under siege from demons while in a police station, Ruby shows up, able to get in through a salt line damaged unwittingly by the deputy. She tells them that demons are from Lilith, Sam's demonic rival from "the west," and tries to convince Sam that the solution is a spell she knows that will "vaporize" all demons within radius - including herself. However the spell requires the sacrifice of a virgin. Nancy volunteers but Dean is vehemently against the plan, instead he convinces Sam that they need to just open the doors and fight off the hoard themselves. Exasperated, Ruby leaves.
After the boys have escaped, seemingly victorious over the demons, Ruby turns up at their motel room & tells them to turn on the television, where they find out that everyone left in the police station was killed by Lilith.
In an last attempt to save Dean from his deal, Sam summons Ruby. She tells him that he contains the power necessary to defeat Lilith, but Dean intervenes and in the ensuing struggle traps her beneath a devil's trap and steals Ruby's knife.
Ruby escapes and tracks the boys to the house where Lilith is tormenting a family. On entering the house they find the little girl Lilith was possessing is human again. Sam turns to Ruby for help again, but she says it is too late to save Dean. As the hellhounds come for Dean, the boys barricade themselves in a room. Dean, who is able to see the true face of demons, realizes that the body possessed by Ruby now contains Lilith. Lilith says she has sent Ruby "far, far away."
Ruby has returned and possessed another body to walk among humans. Since Dean's death, she apparently has taught Sam to use his powers, among them the power to exorcise demons by forcing them out of their host bodies with the sheer power of his will.
Dean demands Sam to tell him why he trusts Ruby. In flashback we find out that while Dean was dead Lilith had released Ruby from Hell, on the condition that she would kill Sam. She instead kills the demon with her and tells Sam she is there to help him. A grief-stricken Sam rejects her help, and demands that she vacate the body she is possessing.
Ruby then possesses the body of a woman in a coma who is brain dead, and whose soul has left her body, and returns to Sam. She offers to help Sam use his powers so he can take revenge on Lilith and he accepts. He is unsuccessful at first in exorcising demons, and becomes even more despairing. Ruby tells him things will get better with time, and seduces him. After that, Sam finds omens that lead him to Lilith and he pursues her despite Ruby's warning not to. Sam walks into a trap, and is attacked by two demons until he is rescued by Ruby. She kills one with her knife and Sam successfully exorcises the other.
She later possesses the body of a maid at the hotel where Sam and Dean are so she can warn them that demons are closing in on them.
After Anna repels Uriel and Castiel; Sam, Dean, Ruby and Anna take refuge at Bobby's place. Pamela Barnes arrives and helps Anna remember that she was an angel who chose to be human. They travel to Kentucky searching for Anna's grace, only to find it gone. Anna then receives a message that unless Dean hands her over to the angels, they will send Dean back to Hell.
Ruby goes to a crossroads and reveals herself to Alastair. She offers to give up Anna, if Alastair will let her and the Winchesters go. He captures and tortures her with her own knife. She won't reveal Anna's location verbally, but she will take him there.
Ruby takes Alastair to where Anna and the boys are and the demons and angels attack each other. Anna get's her grace back from Uriel. During the process, Alastair disappears. Uriel and Castiel leave, and we find out that Ruby was part of Sam's plan to bring the demons and angels together to get them to fight each other.
Ruby accuses Sam of wasting time - thirty-four of the seals have been broken. Sam says that he doesn't know where the seals are or how to stop them from being broken. Ruby counters that he needs to go after the source of the problem - Lilith. Sam refuses and Ruby leaves.
Sam and Dean are heading to meet Ruby, who has some leads on Lilith, when Castiel and Uriel kidnap Dean so he can interrogate Alastair. When Ruby arrives, she uses a spell to help locate where Dean is being held. Sam then tells her that "its been weeks" and he "needs to be strong." Ruby draws a knife across her arm and Sam sucks her blood - the source of his growing powers and abilities.
After Sam escapes from Bobby's panic room and meets up with Ruby. After letting him feed on her, Ruby tells Sam there are only two or three seals left to be broken. She says only "Lucifer's first" can break the final seal - and that is Lilith. This renews Sam's desire to kill Lilith. She says she has a lead on a demon close to Lilith who is nearby.
Ruby helps Sam capture Lilith's minion who reveals where Lilith will be. When Sam confronts Lilith, Ruby watches on with a smug smile and when Dean arrives, telekineticaly locks him out. When Dean starts to get through to Sam with his yells, Ruby yells at Sam to kill Lilith which he eventually does. After Lilith is dead, Ruby reveals to an appalled Sam that she has been working with Lilith all along to free Lucifer. She tells Sam he didn't need the demon blood, that the choices he has made all year have helped him tap into his own power.
Ruby says Sam was the only one who could brings this about but before she can say why, Dean finally breaks in and rushes forward. Ruby turns to confront him, telling him smugly "its too late." Dean doesn't care and as he charges, Sam grabs a shocked Ruby from behind and holds her in place as Dean stabs her with her own knife, killing her.
Sam reveals that Ruby had taught him how to make hex bags, which he and Dean use to hide themselves from angels and demons. He apologizes to Bobby for not listening to him and Dean about Ruby. When Meg appears in her new meatsuit, Dean initially assumes that she is Ruby returned before Meg encourages him to think further back. At the end of the episode, the rift Ruby caused between the brothers continues when Dean admits that, because of how Sam betrayed him in favor of Ruby, he doesn't feel that he can trust Sam anymore.
When Gabriel places Sam and Dean in the Japanese game show, the question the show's host asks Sam is for the name of the demon he chose over his own brother. Sam doesn't understand the question because he doesn't speak Japanese and after he fails to answer in time, the host reveals that the answer was Ruby.
At the end of the episode, Sam admits that he used to blame Ruby for making him feel angry at everyone all the time, but now acknowledges that it's something wrong with him rather than something that she did to him.
Angry that Dean is willing to work with Crowley, Sam brings Ruby up and compares how he had trusted her to how he had trusted Brady. Right before Sam kills him, Brady taunts Sam about how he had always been so easily manipulated by demons like Ruby and suggests that it is because he is just like them, which Sam seems to dismiss.
Sam and Dean initially mistake Genevieve Padalecki for Ruby before realizing that she is the actress who played Ruby in Season 4. When Dean first realizes that Sam's actor is married to Genevieve, he is upset with Sam for marrying "fake Ruby" and Sam gets flustered.
After her knife fails to kill Abaddon, Henry tells Sam and Dean that they would need an "ancient demon-killing knife of the Kurds" to kill a demon and asks where they got one when Dean shows him the knife. Dean tells him that it was from a demon, but doesn't elaborate on the Winchester history with Ruby.
