Queen Margaery Tyrell was the only daughter of Lord Mace Tyrell and Lady Alerie Tyrell, granddaughter of Lady Olenna Tyrell and sister of Ser Loras Tyrell. Margaery became Queen Consort through her marriage to King Joffrey Baratheon, and later his younger brother, King Tommen Baratheon, following Joffrey’s death. However, a charge of perjury and a false dedication to the Sparrow movement led to her downfall as she was eventually killed along with her brother and father when the Great Sept of Baelor was destroyed with wildfire as orchestrated by Cersei Lannister to reclaim her lost power.
Margaery is the only daughter of Lady Alerie Tyrell and Lord Mace Tyrell, the Lord Paramount of the Reach. The Reach is one of the constituent regions of the Seven Kingdoms and House Tyrell is one of the Great Houses of the realm. Margaery was raised in privilege in the family seat and regional capital of High garden. She is close to her brother, Ser Loras Tyrell, the Knight of Flowers. She is also close to her handmaidens, Sera Durwell and Mira Forrester, who followed her to King’s Landing from High garden. She is said to be as beautiful as she is clever.
Margaery marries King Renly Baratheon, the lover of her brother Loras, though she’s aware of their relationship. Two weeks afterward they have not yet consummated their marriage. Renly camps his army in the Stormlands, near his seat of Storm’s End, and holds a tournament for his followers. Margaery is disappointed when Loras is defeated in the final bout by Brienne of Tarth. Catelyn Stark arrives to treat with Renly on behalf of her son Robb Stark and Margaery greets her warmly. Margaery encourages Renly to produce an heir with her but he is unable to become aroused by her. She is pragmatic about his desires and shocks him by offering to bring Loras into their bed.
King Joffrey Baratheon’s Master of Coin Petyr “Little finger” Baelish also visits the camp to treat with Renly. He makes a point of provoking Margaery about her husband’s sexuality and she affirms her loyalty to Renly. Renly treats with his brother King Stannis Baratheon but is unable to reach a compromise. Renly is killed in mysterious circumstances and his Kings guard Brienne of Tarth is blamed for his death. Margaery convinces Loras to flee the camp with her before Stannis arrives. Little finger accompanies them to High garden having gauged Margaery’s ambition to become Queen. Petyr sways House Tyrell into siding with House Lannister. As a result, House Lannister is victorious at the Battle of the Blackwater.
In a ceremony to celebrate victory, King Joffrey tells Loras he may ask anything of him in return for his aid. He asks Joffrey to wed Margaery to cement the new alliance between their Houses through matrimony. Margaery states she has heard of Joffrey’s courage and come to love him from afar. Joffrey states that he has heard of Margaery’s beauty and reciprocates her feelings but balks at setting aside his betrothal to Sansa Stark. He is convinced by his courtiers that Sansa’s family’s status as attainted traitors is reason enough.
Margaery, accompanied her betrothed King Joffrey, returns from the Great Sept of Baelor in a heavily guarded palanquin. Against official protocol, she stops the procession in Flea Bottom unexpectedly. To the shock of her guards and the bewilderment of Joffrey, Margaery steps out of her carriage and began exploring the streets, despite the warnings of danger and lack of hygiene from her handmaiden.
She eventually arrives at an orphanage and begins interacting with the children. Meanwhile, her servants distribute bread and toys, earning her the love of Flea Bottom’s small folk. That evening, Margaery and her brother Loras Tyrell dine Joffrey and his mother, Cersei Lannister. Cersei is unhappy with Margaery’s earlier actions and admonished her boldness; reminding her that her impromptu charity work took place on the same streets where the royal party was assaulted weeks earlier. During this argument, Joffrey defends Margaery and criticises his mother. As a result, Cersei realises that Margaery is adept at winning the hearts and minds of her people, a skill which Cersei lacks.
Later, Margaery and her grandmother, Lady Olenna Tyrell, invites Sansa for a private meeting with them at the gardens of King’s Landing. Loras escorts Sansa to the gardens for the meeting. During the meeting, Lady Olenna dismisses Mace as a fool for supporting Renly Baratheon’s claim to the throne. By contrast, Margaery speaks well of her late husband.
During the meeting, Olenna insists that Sansa tell them the truth about what Joffrey was like since Margaery is to marry him. While Sansa is initially reluctant to share her feelings, she admits that Joffrey is a “monster” since he had reneged on his earlier promise to spare her father’s life. While Olenna is disappointed at these revelations, she is not surprised given the rumours that have been circulating about Joffrey’s public outbursts. While Sansa is worried that this would mean that the Tyrells would cancel their proposed marriage alliance (meaning Sansa will be stuck with Joffrey again), Olenna assures her that her son Mace is too intent on Margaery entering into a royal marriage to cancel it for anything.
Later, Margaery is summoned to Joffrey’s chambers to see if she needs anything before he leaves on a hunting trip. While Joffrey has previously been easy for Margaery to manipulate, Cersei was apparently able to plant one seed of doubt in his mind; the fact that Margaery was married to his uncle Renly (and thus, already had sex with another man), whom Cersei described as a “traitor and known degenerate”.
When questioned, Margaery says that she was ordered to marry a traitor as her family duty, but Joffrey implies that this still means he must have had sex with her. Joffrey angrily questions Margaery about the relationship and she delicately placates him by feigning demure shyness and painting herself as a dutiful, but frustrated, bride. She uses the rumours about Renly’s homosexuality to redirect Joffrey’s anger, stating that Renly always found excuses to avoid sex, but, in one instance, drunkenly suggested “something that sounded very painful and could not possibly result in children”, which draws her new fiance’s sympathy.
Joffrey tells Margaery he had considered making Renly’s perversion punishable by death. Margaery eventually manages to divert attention to the new custom crossbow Joffrey’s had made for his excursion. It quickly becomes apparent that Joffrey is excited by violence and sadism, so she flirts with him by complimenting the crossbow and musing about killing something herself. Easily played, Joffrey offers to take her with him to share in the excitement of killing something.
Later, Joffrey gives Margaery a tour of the Great Sept of Baelor, where their royal wedding is scheduled to be held. They are accompanied by Cersei and Olenna. During their tour, Joffrey talks about the various Targaryen kings who were buried within the Great Sept. Margaery feigns interest in Joffrey’s topic but his mother Cersei is annoyed. Cersei then tries to dissuade Margaery, suggesting that the deceased Targaryens the two are discussing are a macabre subject. However, Margaery insists that she finds the historical aspect fascinating. She then tells Joffrey that she is glad that the tombs are preserved, and although she understands the actions of Aerys were unforgivable, she also believes the Targaryens were great artistic patrons.
While Cersei and Olenna were engrossed in a conversation about the men in their lives, Margaery manages to convince Joffrey to greet the crowd outside. Having been somewhat placated by Margaery’s charity, the crowd happily cheers for the pair. As a result of this incident, Cersei feels that she had lost control of Joffrey to the Tyrells. She comes to fear that the Tyrells do not have her family’s interest at heart. In response, the Queen Regent orders Little finger to spy on the Tyrells.
Margaery Tyrell later finds Sansa Stark praying in the gods wood, dismisses the Lannister guards and engages in pleasant small-talk. Margaery plays a small joke on Sansa by saying that her cousin died of a pox which made her face melt off, but is just trying to brighten her spirits. Margaery then invites Sansa to visit High garden in the Reach someday. Sansa believes that Cersei won’t allow her to leave the city, but Margaery wryly points out that Margaery’s authority will take precedence when she is Queen. Margaery points out that if Sansa were to marry Loras, then she would belong in High garden anyway. The thought of this makes Sansa choke out tears of joy.
Later, Ser Loras invites Margaery and Sansa to watch him sparring with his squire in the castle gardens. During that time, Sansa praises Loras’s swordsmanship and expressed her interest in marrying Loras, something the Tyrells have been plotting to keep her from being used by Baelish or the Lannisters, and to bring the North under the control of House Tyrell, instead of their opponents. Margaery replies that she would “plant the seed” of the idea after she and Joffrey marry. While Sansa is sceptical that Joffrey would let her go, Margaery is confident that he would do it to please his betrothed. Unknown to Margaery and Sansa, Ser Loras later engages in a sexual encounter with his squire Olyvar.
During this meeting, Loras briefly mentions that he is to be married to Sansa. Unknown to Loras, Olyvar is a spy working for Little finger, who in turn reports to Cersei. In response, Cersei’s father Lord Tywin Lannister arranges for Cersei and her brother Tyrion Lannister to marry Loras and Sansa, respectively, in order to curb the ambitions of House Tyrell and to bolster the marriage alliance between the Lannisters of Casterly Rock and the Tyrells of High garden.
While Sansa is unhappy about this arranged marriage to a Lannister, Margaery consoles Sansa by reminding her that Tyrion was far from the worst Lannister, and that Tyrion might be able to make her happy given his skills as a lover. Later, Margaery also attends Sansa and Tyrion’s wedding. Prior to the wedding reception, she attempts to ingratiate herself with Cersei, commenting that they wills technically be sisters soon. However, Cersei rebuffs her friendship by telling Margaery about the story behind the “Rains of Castamere”.
She explains that the song refers to House Lannister’s destruction of the rebellion of House Reyne of Castamere. This is meant to imply similarities between the ambitions and position of Houses Reyne and Tyrell and that the same fate may fall upon House Tyrell if they plot against the Lannisters. Cersei also threatens to have Margaery strangled in her sleep if she ever dares to call Cersei sister again. During the wedding dinner, Margaery is seated with her grandmother Olenna, who talks about what the dynamics of the Lannister and Tyrell families will be after Loras married Cersei, with Margaery shooting her grandmother a withering glare when Loras storms out.
Olenna assists Margaery in picking out a necklace for her upcoming wedding. She selects the finest of those on offer, noting affectionately that it is similar to one she received from Margaery’s grandfather on her 51st name day. Olenna chucks the piece over the rampart and into Blackwater Bay and orders the Tyrell handmaidens to canvass every jeweller in King’s Landing for better offerings.
After they are left alone, Margaery sardonically suggests letting Joffrey pick out the necklace, which knowing him will likely consist of severed sparrow’s heads. Olenna cautions Margaery to mind what she says, even with her. They are shortly interrupted by Brienne of Tarth, who has come to speak with Margaery about Renly’s death. In private, Brienne explains what she saw and how the shadow had Stannis’s face, and assures Margaery that she will find a way to avenge their king. Margaery reminds Brienne that Joffrey is their king, now. Brienne apologises for any offence given, but Margaery assures her that none was taken.
Margaery’s wedding to Joffrey goes off without a hitch. At the wedding feast, however, Joffrey’s cruelty and twisted sense of humour become apparent in the tasteless performance of the War of the Five Kings he has performed and in his treatment of his uncle Tyrion. Margaery is only barely able to distract him, proving her control over him is fleeting. Everything is cut short, however, when Joffrey is poisoned and dies in front of Margaery’s eyes.
As the capital is in “mourning”, Margaery inquires to Olenna if she is actually the queen or not. Her grandmother tells her she is more so a queen now than she ever was with Renly, but the lack of consummation in both circumstances limits her authority. Nevertheless, advises her to not press the issue just yet. She tells Margaery of how she felt when Luthor Tyrell died, but also says that Margaery is at least lucky that her third marriage should be easier than the other two. Margaery is surprised by this, but Olenna points out that the Lannisters need their alliance with the Tyrells far more than they do.
Margaery learns, to her disappointment, that Olenna intends to return to High garden before Tommen’s coronation. Her grandmother tells her that she should be able to handle things herself from this point. Before she leaves, Olenna tells her about how she seduced Luthor Tyrell to get out of her engagement to a Targaryen, and advises Margaery to make her move on Tommen while Cersei is still distracted over Joffrey’s murder. Margaery is confused by Olenna’s certainty that Tyrion is innocent, until Olenna makes it clear that she would never have allowed Margaery to marry “that beast”, heavily implying that it was she who poisoned Joffrey.
Later that night, Margaery steals into Tommen’s bedchamber, apparently easily sneaking past the Kings guard. She discusses rumours of their upcoming wedding with him and interacts in a friendly manner with his cat, Ser Pounce. Margaery and Tommen bond over their relief that they won’t have to live in fear of Joffrey anymore. Margaery asks if she can visit him again in secret; Tommen agrees. Realising that she must be maternal in her initial manipulation of him, Margaery gives him a kiss on the forehead as she leaves.
Still dressed in mourning clothes, Margaery watches Tommen’s coronation from the side gallery of the great hall. Cersei approaches her and engages her in conversation. To Margaery’s surprise, Cersei says that the things Joffrey did shocked her, then asks rhetorically if Margaery thinks many things shock her. Cersei asks if Margaery still wants to be the queen, to which the lady replies that she hasn’t thought about it. Cersei ignores the obvious lie and says that Tommen will need someone to guide him; apparently, she doesn’t have the will to fight about Margaery being that someone anymore. Cersei and Tywin later set the date of Margaery and Tommen’s wedding to right after the mourning period is over, a fortnight from the coronation.
Along with her brother and father (who is one of the three judges), Margaery is present at the trial of Tyrion Lannister. Although she wasn’t close to Tyrion, she looks visibly displeased at the proceedings, well aware that Tyrion is innocent and the trial is a farce. Nonetheless, Margaery remains silent throughout the trial. Guiltily, knowing that her grandmother is the real conspirator, Margaery watches as the trial goes awry and Tyrion demands a trial by combat.
Margaery, along with lords and ladies from all over the Seven Kingdoms, stands on the Great Sept of Baelor as Cersei Lannister arrives to mourn the loss of her father. During the reception at the Red Keep afterwards, Cersei notices her exchanging a few close words with Tommen and holding his hand briefly. Later on, Margaery interrupts Loras as he is in bed with Olyvar. Irritated at her brother’s lack of discretion, she dismisses Olyvar. Loras is puzzled by Margaery’s relaxed attitude, as Tywin’s death means Cersei won’t be forced to marry Loras and be sent off with him to High garden, which means Margaery will have to contend with her mother-in-law at the capital. Margaery implies that may not be the case.
Tommen and Margaery are finally wed, much to the dismay of Cersei. That night, they consummate their marriage. They are elated and discuss their future together. Tommen tells Margaery how he thinks that his mother is unhappy in King’s Landing. Seeing an opportunity to get rid of Cersei, Margaery manipulates Tommen into thinking that as long as Cersei stays in King’s Landing, she will continue to treat him like a child, like a mother lioness watching over her cub.
When Tommen tries to convince his mother to leave King’s Landing, Cersei deduces that this is Margaery’s doing and pays her a visit, only to find Margaery busy gloating about her “exhausting” night with the King. Greeting her new mother-in-law, Margaery, now more confident than ever and even dressing like Cersei, rubs her queenship and marriage in Cersei’s face, getting less subtle with each barb. Seeing herself losing, Cersei walks away. Margaery and her entourage laugh following her exit.
Later, however, Margaery becomes angry when her brother is arrested by the Faith Militant. She confronts Tommen, who eventually claims that his mother was not responsible and there was no way to free Loras without bloodshed, but Margaery, who has much more court and political experience than Tommen, is perfectly aware that Cersei played a role in her brother’s arrest in order to divide her and Tommen. She subsequently decides to write to Olenna for help.
Olenna arrives shortly after and speaks with Margaery, sharing her belief that even though the Faith Militant arrested Loras, Cersei was the true mastermind. Later, at Loras’s Holy Inquest, Margaery is called to testify and she backs her brother’s denial towards the charges against him. However, Olyvar is called in to give testimony, though it is clear he has been instructed by Cersei. He confirms the accusations against Loras, who is to be put on trial. Margaery, to her horror, is also arrested by the High Sparrow for giving false testimony, and dragged from the room while calling Tommen for help.
Margaery is placed in a cell beneath the Sept of Baelor. Cersei comes to visit her, bringing her dinner and offering her condolences, but by now, Margaery knows of Cersei’s part in the plan to have her and Loras arrested, accuses her of lying and ultimately orders her to leave, throwing the bowl of stew at her and calling her a “hateful bitch”. The High Sparrow later tells Cersei that both Margaery and Loras are to stand trial.
Still in her dank cell, a bruised Margaery is being read at ceaselessly from the Seven Pointed Star by Septa Unella. Margaery inquires about Loras’s condition, but Unella says she must confess her sins first and moves to strike her. At that precise moment the High Sparrow steps in and stops Unella, ordering his acolyte to attend the Faith’s “other guests.” His High Holiness admits that at times Unella takes her devotion too far; still Margaery’s questions concerning Loras remain unanswered. Instead, the High Septon mentions that Tommen misses his wife terribly, and that the love between husband and wife is sacrosanct, and that sins, however, have a way of leading decent people away from all things sacred and into wickedness. Margaery claims she has committed no sins. The High Sparrow gently reprimands the Tyrell Queen, asking if she considers herself to be “wholly without sin.” When Margaery finally acquiesces that no one is perfect and that everyone makes mistakes, the High Sparrow assures her she’s on the right path but has many miles left to go.
Some time later, Margaery is again brought to speak with the High Sparrow. He relates his story about how he began to reject the material world, but Margaery calls him out for quoting from the Book of the Stranger. She admits she isn’t that familiar with The Seven-Pointed Star, but Septa Unella has been reading passages from it at her. The High Sparrow agrees that Unella has a habit of reading at people and finishes his story, allowing Margaery to see Loras. Seeing that her brother has nearly given up hope, Margaery encourages him to keep fighting.
Eventually, the High Sparrow allows Tommen to visit Margaery, who now appears clean and kempt, and unnervingly cheerful considering her recent ordeal. Margaery professes to Tommen her newly found devotion to the Faith. She admits that although she had always put on a kind and caring persona in the past, she had done so with ulterior motives. Upon being asked by Tommen of Loras, she states that he must atone for his sins. This convinces Tommen to unite the crown and the faith, intent on bringing a new era for the Seven and for Westeros.
Just before her own walk of atonement on the steps of the Great Sept of Baelor, her father, along with his army, and Jaime Lannister arrive in order to prevent her humiliation. Jaime threatens to incapacitate the Faith Militant by force, but before any hostility can occur, the High Sparrow announces King Tommen as a newly converted follower of the Faith and calls off Margaery’s atonement, claiming that she has done her part by bringing Tommen onto their side. The Queen Consort then joins her husband in a unification of the Baratheon monarchy and the Faith of the Seven.
Margaery is in the Sept reading from the Seven-Pointed Star when the High Sparrow arrives. They quote verses about the Mother together before discussing the poor. The High Sparrow then asks Margaery why she has not been sharing the marriage bed with Tommen, prompting Margaery to explain that the desires that once drove her no longer do. The High Sparrow responds that Margaery has a duty to her king, country, and the gods: she must produce an heir. The High Sparrow then reveals that he “fears” for her grandmother, stating that while she is a strong and powerful woman, she is also an unrepentant sinner. He tells Margaery that she must bring her grandmother around to their way of thinking or else there will be consequences for “her body and soul.” The implied threat is not lost on Margaery.
Under the supervision of Septa Unella, Margaery meets with Olenna inside the Red Keep. Olenna openly insults Septa Unella, whom Margaery defends, saying she has been a true friend and teacher. Olenna reacts with disgust, pulling Margaery into another room in an attempt to have some privacy, but Septa Unella follows them. Olenna begins verbally attacking Septa Unella, stating that she needs a good bashing. Once more, Margaery comes to the Septa’s defence. Olenna questions what the Sparrows have done to her, and Margaery replies that Olenna marched against the gods. Olenna argues that they marched for Margaery and Loras’s sake.
Margaery replies that the gods could have punished Olenna and her allies for their blasphemy, but they instead showed mercy. Olenna reminds Margaery that Loras is still imprisoned and that that is hardly mercy. Margaery assures her that Loras may return to High garden following his atonement, though he will have to renounce his titles and live the rest of his life in penitence. Olenna is rightfully horrified by this due to the fact that Loras is the heir to High garden and believing that Margaery’s loyalties towards her family and house have weakened. Before she can say more, Margaery kneels in front of her and urges her to return to High garden. Olenna says that she will never leave Margaery.
Margaery repeats her plea, this time with a marked sense of urgency, secretly slipping a piece of paper into her grandmother’s hand. Understanding the silent message, Olenna relents. She tells Margaery that she will see her soon, and the two share a hug. During the hug, Margaery’s mask slips for a split second because of the emotion. After Olenna leaves, Margaery cheerfully asks Septa Unella if she would like to pray. Outside the room, Olenna unfolds the note to find a rose—House Tyrell’s sigil—drawn on it. This reassures her that Margaery’s true loyalty remains with her family.
At Cersei and Loras’s trial, Margaery stands with her father in the Great Sept of Baelor, and watches from the sidelines as Loras renounces his allegiance to House Tyrell, confesses to his crimes and agrees to join the Sparrows. Presumably, Margaery becomes heir to High garden for the final moments of her life after her brother’s disinheritance. She comforts her father and restrains him from intervening when the Faith Militant begin carving the seven-pointed star into Loras’s forehead. When Margaery realises Cersei is not present, the High Sparrow sends Lancel to bring her to the sept by force. When Lancel himself does not return after a prolonged period of time, Margaery suggests to the High Sparrow that Cersei’s absence and that of her son indicates that she is plotting to harm them.
Margaery then attempts to evacuate the Sept, taking the frightened Loras with her. Clearly underestimating Cersei, the High Sparrow dismisses this notion and has his Sparrows keep the Tyrell siblings from leaving the sept, along with everyone else present. Powerless to do anything or reach her father in their final moments, Margaery gives the High Sparrow a knowing look, angered at his lack of understanding and his ignorance of Cersei’s unmatched cruelty. He then realises their doom is nigh, and Margaery clutches to her brother as the sept erupts in an explosion of wildfire, killing everyone inside, including Margaery, Loras, and their father.
Although Cersei is initially delighted in wiping out her enemies in the Faith (and a rival in Margaery), as a result of Margaery’s death, Tommen commits suicide after he sees the burning sept from his chambers, leading to Cersei seizing the Iron Throne. Without Margaery to act as a link in the alliance between House Tyrell and House Lannister, and vengeful of her progeny’s death at the hands of Cersei, Olenna aligns High garden’s forces with Daenerys Targaryen following a meeting with the Sand Snakes of Dorne.
During the meeting at Dragon stone to discuss marching full force on King’s Landing, Daenerys states that she does not want to be known as Queen of the Ashes (i.e. she doesn’t want to rule over a country that must be destroyed to be conquered). Olenna remarks to Daenerys that Margaery was the most admired Queen within living memory, among both the nobility and the small folk, but now all that remains of her is ashes. She concludes that for Daenerys to claim the Iron Throne, she must be feared as well as loved, a trait Margaery lacked.
After the death of her grandmother at the Sack of High garden, the Lannister-Tarly forces are attacked by Daenerys Targaryen, in which the surviving lords are asked to swear fealty to Daenerys. Despite the threat of death, Randyll Tarly announces that he already has a Queen in Cersei. However, Tyrion reminds him that Cersei killed Margaery, who was the rightful Queen Consort of the Seven Kingdoms.
When Jaime Lannister returns home to King’s Landing after the sacking of High garden and the Battle of the Goldroad, he informs Cersei of Olenna’s involvement in the murder of Joffrey, and explains her motivations to kill him in order to protect Margaery from the gruesome nature of Joffrey. In addition, Margaery would have been better able to control the more calm-natured and naive Tommen. He remarks that Olenna, her son and grandchildren are dead and that House Tyrell is officially extinct.
Margaery’s beauty was equaled by her cleverness, which she had in abundance. A true protégée of her grandmother Olenna, she was a gifted manipulator who knew how to manoeuvre her way in court politics. Margaery’s strength was in her ability to win the minds and loyalties of her subjects, which had proven to be a threat to those who rival her family, such as the Lannisters. She demonstrated her formidable skill in her charity work to win over the commoners of King’s Landing, as well as her manipulation of Joffrey by making him think she was excited by his dark impulses. In return, Margaery gained the acceptance of both her subjects and Joffrey, who was an unpredictable and uncontrollable madman to everyone else, including his mother. This proved to be a threat to Cersei, who only relied on the fear of her family name and her position as a source of power.
Margaery possessed the tact and politeness that Cersei lacks. While Cersei is blunt and often rude, Margaery was capable of exuding the courtly behaviour and courtesies expected of a queen – while still privately engaging in palace intrigues to increase her family’s power. Cersei scorns her status as a woman in a realm dominated by men, though she is willing to use sex as a weapon to seduce those she needs (such as her cousin Lancel). In contrast, Margaery worked within the social standards of “proper” femininity in Westeros, but adeptly turned them to her favour, to orchestrate political machinations from behind the scenes.
Although Margaery had to develop many different facades depending on who she is trying to manipulate, she was shown to genuinely have a good heart, compassion, and empathy. Margaery had loving relationships with all of her family members. She loved her brother Loras and was entirely tolerant of his homosexuality – to the point that when her father contracted a marriage-alliance between herself and Loras’s own lover Renly, she acknowledged that it was a paper marriage, and was quite frank that she had no issues with her new husband continuing his sexual relationship with her brother. In addition, she rather resourcefully suggested utilising Loras in order to help conceive a child with Renly. She also showed genuine concern for Sansa Stark and tried to form a friendship with her, even offering her help to get out of King’s Landing once married to Joffrey – though this may have been in part because she had the more long-term goal of good relations with the North, sensing that the unstable Lannisters wouldn’t be in power forever. She shared a very strong bond with her grandmother, sharing her acuity for manipulation and political manoeuvring. Though she had developed many facades in order to sway the opinions of others in her favour, she was extremely loyal to her family and house, and would go to great lengths to keep them safe. Though she was willing and able to feign affection for Renly and Joffrey, she genuinely cared for Tommen (she may not have exactly loved him, but it’s quite clear that she at least liked him) and bore him no ill will when he failed to stop the arrest of both her and her brother, a feeling which he reciprocated to such an extent that he willingly committed suicide when she was murdered by Cersei.
It should be noted that Margaery herself was not technically outmanoeuvred by Cersei in the end: Margaery, even without having any idea of the wildfire plot, realised the threat of Cersei’s absence, and thus ordered an evacuation, potentially with time to spare to get everyone out. It was, instead, the High Sparrow who was outmanoeuvred, refusing to listen to Margaery and not accepting that his plans were about to collapse.
