Canon
Steve Harrington

Steve Harrington is portrayed by Joe Keery. While starting out as a typical jock character, Steve has grown into a more paternal and caring character as the show has progressed, a development that has received widespread acclaim from critics and fans alike and has led to Steve becoming one of the show’s most beloved and enduring characters. Initially a part of the recurring cast, Joe Keery was promoted to the main cast in the second season. Steve is a side antagonist turned protagonist of season 1, and one of the main protagonists of season 2 and season 3.

Season 1 :

Steve is initially portrayed as a stereotypical 1980s jock character, antagonistic and unlikable. Steve had been dating Nancy Wheeler but after he harasses Jonathan Byers by breaking his camera, Nancy seems to become close to Jonathan. Steve accosts Jonathan, but Jonathan beats him in a fight and Steve sees the error of his ways. Traveling to the Byers' home to apologize, he becomes involved in Nancy and Jonathan's fight against the Demogorgon, which they defeat. At the conclusion of the season, Nancy buys Jonathan a new camera and Steve continues his relationship with Nancy.

Season 2:

Steve's relationship with Nancy is stressed, and he breaks up with her after she will not say she loves him. He calls her out after her drunken tirade at a party where she calls their relationship fake. Steve also finds himself at odds with Billy Hargrove, a new student at the school who seeks to become its tough guy. Steve becomes involved with Mike Wheeler and his friends after Dustin asks him to help find his "pet" D'Artagnan, unaware it is a Demogorgon. Steve and Dustin bond over how to talk to girls, and soon Steve takes Mike, Lucas, and Billy's stepsister Max under his wing. Steve protects the children as Demodogs start ravaging across Hawkins, giving time for Eleven and Jim Hopper to close the gate to the Upside Down, and for Will Byers to have the Mind Flayer exorcised from his body.

Season 3 :

Now graduated from high school, Steve works at the Scoops Ahoy! ice cream parlor at Starcourt Mall with Robin Buckley (Maya Hawke), a former classmate who teases him frequently. Dustin, having returned from science camp and set up a ham radio tower to talk with his new girlfriend Suzie in Utah, gets Steve's help to translate a Russian radio message he overheard. Robin helps with the translation, indicating a site at the mall, and Lucas' sister Erica (Priah Ferguson) is recruited to sneak into the site in exchange for free ice cream. Steve, Robin, Dustin, and Erica find a secret Russian base under the mall that is attempting to open a portal to the Upside Down. Though Steve and Robin are captured and drugged, Dustin and Erica help save them and return to the surface to warn the others. Whilst coming down off the drugs, Steve admits he is attracted to Robin and learns that Robin is a lesbian, yet accepts her sexuality. In the following battle with the Mind Flayer, Steve helps to stop the possessed Billy from ramming the car that the others are using to escort Eleven away, and joins the rest in distracting the Mind Flayer with fireworks as the gate in the Russian base is shut down. With the mall's destruction from the battle, Steve and Robin lose their jobs at Scoops Ahoy! and get work at the local Family Video.

Nancy Wheeler

Nancy Wheeler is portrayed by Natalia Dyer. Nancy is the sister of Mike Wheeler and the ex-girlfriend of Steve Harrington. Nancy starts investigating the disappearance of Will Byers when her friend Barbara Holland goes missing as well. She teams up with her future boyfriend Jonathan Byers to investigate Will and Barbara's disappearance, which leads to her discovery of the Upside Down.

Season 1 :

Nancy is Ted and Karen Wheeler's oldest child. She has a younger brother, Mike, and younger sister, Holly. She is introduced as best friends with Barbara Holland, who doesn't agree with Nancy's new relationship with Steve Harrington. She is also shown to have grown somewhat distant from her brother and his friends, and is unaware of Jonathan's secret feelings for her. After Will goes missing, Nancy offers her sentiments to Jonathan, something which distances herself from Steve's other friends, who think Jonathan is a freak and is likely responsible for Will's disappearance. Nancy becomes involved in the investigation after Barbara disappears while she is having sexual relations with Steve. Due to her guilt for abandoning Barbara and her motivation to find out what happened to her friend, Nancy meets up with Jonathan to discuss Will and Barbara's disappearance.

In the course of their investigation, Jonathan and Nancy accidentally discover the alternate dimension where the creature that took Barbara - The Demogorgon - resides, known as "The Upside-Down". Nancy successfully escapes from The Upside-Down thanks to Jonathan's help and the two retreat back to Nancy's house, where they sleep in her bed to comfort each other. This is witnessed by Steve, who takes the encounter out of context and assumes Nancy is cheating on him. In a fit of rage, Steve's friends Tommy H. and Carol graffiti the Hawkins movie theatre slut-shaming Nancy. Nancy confronts Steve, which results in a fight between Jonathan and Steve, leading to Jonathan's arrest. After Hopper gets a call from the station that Jonathan has been arrested, he and Joyce return to Hawkins where they share the information they know about The Demogorgon. Nancy successfully contacts Mike, who has gone into hiding due to having befriended Eleven and becoming a target of the Hawkins lab. Nancy reunites with Mike and his friends at Hawkins Middle School where they build a makeshift sensory deprivation tank for Eleven to be able to use to find Will and Barbara. Eleven discovers that Barbara has been killed by the Demogorgon, leading to Nancy cementing her determination to kill the monster.

Nancy and Jonathan return to the Byers house to create a distraction, to allow Joyce and Hopper safe passage through The Upside-Down to retrieve Will, luring the Demogorgon to the house with blood. Steve arrives in hopes of reconciling with Jonathan, but ends up becoming witness to The Demogorgon. Nancy and Jonathan ask Steve to leave and save himself, but he finds his courage due to his love for Nancy and re-enters the house, successfully injuring the Demogorgon before it is lured back to Hawkins Middle School, where it is seemingly killed by Eleven. Nancy reconciles with Steve and resumes their relationship, gifting Jonathan with a new camera for Christmas.

Season 2:

One year after the events of season 1, due to the inability to divulge information on Barb's disappearance, Nancy and Steve begin consistently meeting up with her parents and sharing dinners with them. It turns out that Barb's parents have put their house up for sale and they've enlisted a private investigator, Murray Bauman (who is currently harassing Hopper for answers), to uncover Barbara's disappearance. Nancy is still overcome with grief over Barbara's death and begins showing potential signs of post-traumatic stress disorder, believing she is seeing Barbara's ghost following her in the school's library. While attending a Halloween party, Nancy gets drunk and begins verbally berating Steve when he tries to cut her off, leading to a falling out between the two. After Steve angrily leaves the party, she is escorted back home by Jonathan.

Nancy confides in Jonathan and the two arrange a meeting with Barb's mother in the park. At the park, Nancy and Jonathan are overcome with the suspicion they are being watched, and are intercepted by agents of the Hawkins Lab. They secretly record a conversation with Dr. Owens, who explains that he is trying to amend for Brenner's mistakes, admitting to culpability in Barbara's death.

Nancy and Jonathan visit Murray at his residence to see if the evidence is damning enough to lead to the shutdown of Hawkins Lab. Murray suggests that they water down the story to make it more believable to the public. He also figures out that Nancy and Jonathan have sexual tension, suggesting that they share his guest room, leading to them reciprocating their feelings that night.

Upon their return to Hawkins, Nancy and Jonathan find the Byers residence empty and littered with Will's drawings. They head to Hawkins Lab where they soon come across Steve, who has in the meanwhile befriended Dustin, Lucas and Max Mayfield. They head to the front gate where they meet Hopper, Joyce, Mike and a heavily sedated Will, who has become possessed by the Mind Flayer. They return to the Byers house and attempt to interrogate Will, who has been signalling in Morse Code for them to close the gate to The Upside Down. Once they deduce Will's message, the Byers house phone rings, alerting The Mind Flayer to their location. The house becomes swarmed with Demodogs before they are incapacitated by Eleven. The group reunites with Eleven and create a plan which involves Hopper and Eleven returning to Hawkins Lab for Eleven to close the gate, with Joyce and Jonathan going to Hopper's cabin to exorcise Will. Steve encourages Nancy to go with Jonathan and promises to look after Mike and the rest of the kids. With their differences put aside, Nancy accompanies Jonathan in exorcising Will, restraining him and exposing him to numerous heaters. Once the Mind Flayer has successfully exited Will's body, the group signals to Hopper to close the gate.

Nancy later attends the official funeral for Bob and Barbara after Hawkins Lab is exposed and shut down. Nancy and Jonathan volunteer help at the Hawkins Middle School Snow Ball, where she sees that Dustin is alone and rejected. Nancy offers to dance with Dustin and consoles him.

Season 3:

In the summer of 1985, Nancy and Jonathan get internships at The Hawkins Post under the watch of Tom Holloway. Nancy is eager to impress her sexist male co-workers by suggesting story ideas, which usually resulted in demeaning jokes and comments, leaving Nancy humiliated and embarrassed. One night while Nancy is working late, she answers a call to about rats eating Doris Driscoll's fertilizer. Assuming the guise of reporters, Nancy and Jonathan interview Mrs. Driscoll at her house, where they witness a rabid rat she has captured. Nancy's colleagues reject the story calling Driscoll a nut-job, leading to Nancy returning to the house, only to find that Mrs. Driscoll has become infected by the newly resurrected Mind Flayer, eating fertiliser and screaming that she "has to go back".

In the meanwhile, through possessing Billy Hargrove and Tom's daughter Heather, the Mind Flayer possesses Tom and the rest of the Hawkins Post staff, and compels them to fire Nancy and Jonathan to keep them from learning the truth. Still undeterred and despite an argument with Jonathan, Nancy still decides to pursue the story, noticing symptoms in Mrs. Driscoll similar to that of Will's possession, Nancy calls Jonathan and asks to meet up with Will. As they discuss this information, Nancy, Jonathan, Will, Mike, Eleven, Lucas and Max return to the hospital, only for Nancy and Jonathan to find that Mrs. Driscoll is missing and are intercepted by the flayed Tom and his co-worker Bruce. A fight breaks out, with Jonathan killing Tom while Nancy kills Bruce, before the two flayed hosts merge together to form a monster. The monster is wounded by Eleven before retreating to the sewers.

The group takes refuge at Hopper's cabin, but the Mind Flayer manages to track them down and wounds Eleven. The group heads to Starcourt Mall to re-group with Dustin, Steve, Steve's co-worker Robin and Lucas' sister Erica. While there, Hopper, Joyce and Murray arrive who reveal that they know how to close the new opening to the Upside-Down built by a Soviet detachment under the Starcourt Mall. The Mind Flayer arrives at the mall and is fended off with fireworks by Nancy, Jonathan, Will, Lucas, Steve and Robin, as Billy attempts to infect Eleven. Eleven reaches through to Billy, who sacrifices himself to The Mind Flayer to save Eleven, resulting in his death. The gate is eventually closed by Joyce, albeit seemingly at the cost of Hopper's life. After Hopper's death, Joyce takes in Eleven and her, Will and Jonathan sell their house and move away. Nancy and Jonathan share a passionate and emotional kiss goodbye as she watches with her brother, Dustin, Lucas and Max as they leave Hawkins.
