Siobhan "Shiv" Roy is a fictional character in the American HBO satirical dark comedy-drama television series Succession. She is portrayed by Sarah Snook and was created by showrunner Jesse Armstrong, as with the rest of the show's characters. Armstrong initially conceived the series as a feature film about the Murdoch family, but the script never went into production. He later decided to create a new script centered on original characters loosely inspired by various powerful media families.

She is a member of the Roy family, owners of Waystar RoyCo, a global media and entertainment conglomerate, led by patriarch Logan Roy. Shiv is Logan's youngest child and only daughter from his second marriage. As a left-leaning political fixer upon Logan's retirement, Shiv distanced herself from the company until she was offered a leadership position by her father. The various back-and-forths with her family for control of the company, as well as her strained marriage to Tom Wambsgans, become a central part of Shiv's storyline.

Siobhan Roy was born in England as the youngest child and only daughter of Scottish media mogul Logan Roy and his second wife, the English aristocrat Caroline Collingwood.^[1] She has two older brothers, Kendall and Roman, and an older half-brother, Connor, from Logan's first marriage. Gerri Kellman, the general counsel to Waystar RoyCo, is Shiv's godmother.^[2] She relocated to New York City with her father and siblings after her parents divorced.

Shiv is implied to have been treated preferentially by Logan, who affectionately calls her "Pinky",^[3][4] but he focused his efforts solely on her older brothers in grooming his potential successors. Logan's supposed preference for Shiv caused her to have an acrimonious relationship with her mother, who resented the time they did not get to spend together following the divorce.^[5] Disillusioned with her family's right-wing conglomerate, Shiv opted to wield her natural leadership instincts in liberal politics by working as a political fixer.^[6] She was romantically involved with Nate Sofrelli, a fellow political fixer who spent time with Kendall in Shanghai, China after he graduated from college.^[7]

During a turbulent period in her life, presumed to take place after she experienced a painful breakup with a previous partner, Shiv met Tom Wambsgans, a businessman from Saint Paul, Minnesota. The two enjoyed a courtship in France and eventually fell in love, although their relationship is deeply flawed.

Throughout the series, Shiv is shown to be shrewd, competent, and more resistant than her siblings to their father's wishes. She is an "indomitable" presence with a "persistent" sense of determination,^[8] but she is also emotionally troubled.^[9]

Shiv begins the first season of Succession as a political consultant largely distanced from Waystar RoyCo's affairs. During Logan's eightieth birthday celebration, the siblings are shocked when he asked them to sign documents that would give his third wife, Marcia, two seats on the company's board. Kendall offers Shiv and Roman a counterproposal that would name him as Logan's successor and appoint the two of them as co-chief operating officers; the duo immediately rebuff Kendall. Logan suddenly suffers a hemorrhagic stroke and is rushed to the hospital during an argument with his children regarding Marcia's involvement with the trust.^[10]

In the wake of Logan's incapacitation, the Roy children are in disagreement over who should take control of the company. Roman insists that Shiv signs the trust documents alongside him, but she doubts Marcia's role in the company. He then blames Shiv for causing Logan's stroke with her hardball tactics, provoking a physical altercation. Tom spontaneously proposes to Shiv in the hospital; she accepts but wishes that he asked her under better circumstances.^[11] She grows suspicious of Marcia and asks Nate to run a background check on her. Marcia reassures her that she is willing to answer any questions she may have.^[12]

Roman informs Shiv that nude photographs of the husband of her political candidate, Joyce Miller, have leaked online. She unsuccessfully tries to block ATN, Waystar's global news outlet, from airing the story.^[13] Shiv then has a dispute with Tom and his mother-attorney regarding their prenuptial agreement, which does not contain any conditions related to infidelity. Tom wonders if its absence meant that Shiv would be unfaithful to him, but she dodges his concerns.^[14] Shiv then has dinner with Nate, who presents an opportunity for the two of them to work for the presidential campaign of Logan's political nemesis. She spends the night with him in his apartment, albeit in separate rooms. Although they are both engaged to other partners, they remain sexually attracted to each other.^[15]

Shiv attends a weekend-long family therapy session at Connor's ranch in New Mexico, but she prematurely exits to speak with U.S. senator and leftist presidential candidate Gil Eavis. Logan chastises her for meeting with his rival and suggests that she is only marrying Tom because she does not want to be betrayed, causing her to cry.^[16] He then implies that he is aware of Shiv's affair with Nate. She views his knowledge as a veiled threat and refuses to stop working for Gil. Marcia later informs Shiv that Logan would not attend her and Tom's wedding; he appears anyway to avoid bad publicity.^[17] After meeting with Nate, Tom confronts Shiv of her infidelity, which she denies. She then gathers political ammunition for Gil and leverages it to force a truce between him and Logan.^[18] Kendall makes a failed attempt to takeover Waystar during the wedding. After they were declared husband and wife, Shiv finally admits her infidelity to Tom and asks for an open marriage. He forgives her and ejects Nate from the wedding.^[19]

Still feeling betrayed by Kendall's attempted takeover, Shiv and Tom decide to cut their honeymoon short to attend to family matters. They join Logan and the other Roy children at the family's summer home in the Hamptons for lunch. Logan asks his children for their opinion on whether he should sell Waystar. None of them felt comfortable with openly sharing their thoughts, so Logan has them meet him one-by-one in the privacy of his office. During their meeting, Logan offers Shiv the role of chief executive officer (CEO). She is elated, as she always wanted the opportunity, but chooses to not disclose the news to Tom; she simply informs him that he was promoted to ATN's chair of global broadcast news.^[20]

Gil tells Shiv that if he were to be elected president, he would name her his chief of staff. On the other land, Logan suggests that it would take three years for Shiv to fully integrate into her offered role. She finally tells Tom the news; he is excited for her but worries about his plans to inherit the company. Shiv reassures him that his ambitions are not in jeopardy before she mocks him and tells Roman in secrecy to not consider him as a threat. After considering her two options, Shiv quits Gil's campaign and informs Logan that she is ready to work for Waystar.^[21]

Shiv vehemently opposes Logan's plans to takeover Waystar's rival Pierce Global Media (PGM). She asks Tom to talk him out of it before he leaves to participate in the family's hunting retreat in Hungary. While he is away, Shiv enjoys a one-night stand and tries to convince Connor to withdraw from the presidential election. Logan later tells Shiv that it is time to bring her into the company.^[22] On her first day, she observes the daily operations of Waystar as everyone is rushed into panic rooms. She is concerned about Kendall's mental health; he tearfully confides to her his belief that the only valuable aspect of him is his loyalty to Logan.^[23] During a weekend trip to the Pierce family estate in Long Island, Shiv abruptly announces that she was chosen to serve as CEO. Nan Pierce, the head of PGM, agrees to sell the company to the Roys on the condition that Shiv would be named as Logan's successor on the day of the merger. Logan refuses and calls off the deal, but receives a call soon after saying the Pierces changed their mind.^[24]

Shiv Roy and her siblings were inspired by the offspring of real-life business magnates, such as Ian and Kevin Maxwell, Shari and Brent Redstone, and Rupert Murdoch's children.^[25] Jesse Armstrong, the showrunner of Succession, wanted the Roy children to have lived in England for a while, as a way to show that they were "quite international due to being incredibly wealthy."^[26] Sarah Snook originally did not want to audition for Shiv because there was nothing in herself that she found "reflective or accessible" in a "beautiful and wealthy" character.^[27] She recorded a tape anyways and was ultimately called in for a screen test.^[28] The Succession creative team flew Snook from her native Australia to Los Angeles for her final audition, which she completed with Jeremy Strong, who played her older brother and heir apparent Kendall Roy.^[28] Before the audition, she spoke to Armstrong and executive producer Adam McKay on the phone and learned more about their respective interests in comedy, politics, and family dynamics.^[28]

When she was offered the part by Armstrong, Snook turned it down due to concerns with how the series would manage themes of sexism, particularly in the workplace.^[29] "If the world is going to be interested in a bunch of white dudes talking about business, and if I’m the only woman in that, then I’m likely to get sidelined and be like some sort of prop," Snook explained to Variety. "I don’t feel like that personally, nor do I feel like I want to compete for that."^[29] She gave the role a second chance by re-examining the part through the perspective of Succession's creative team. She had blind faith that the role would open an opportunity for her to fight for female characters, rather than being sidelined as one of the only women attached to the pilot episode.^[29] "There’s a focus lens toward that kind of sexism," said Snook. "It is present in the show because it’s present in real life, it’s there, and that’s inherent in the characters’ behavior, as well as the things they say."^[30]
