Jaime Lannister is perhaps the most complex and problematic character on Game of Thrones. Dubbed the Kingslayer and reviled for his incestuous affair with Cersei Lannister, Jaime's narrative path includes redemption, shame, heroism, and heartbreak. But amid all his changes, there is one constant: his blind devotion to Cersei. Even while watching him become a better and more self-conscious man, Jaime still returned to the one who played games, controlled, and emotionally entwined him: his sister and lover, Cersei.
Many fans hoped Jaime would eventually break free from Cersei’s toxic grasp and forge his own path. Yet time and again, he chose her over duty, over love, over honor. His loyalty wasn’t driven by reason or morality, but by deep-seated emotional dependence and a shared identity that had been forged since birth.
This piece delves into ten critical moments when Jaime Lannister demonstrated his loyalty to Cersei, even when it went against reason, sacrificed his principles, or cost him something precious. These instances don't merely demonstrate loyalty; they reveal a man ensnared in an obligation he couldn't escape, regardless of how manipulative or harmful it was.
Times Jaime Lannister proved his blind loyalty to Cersei in Game of Thrones
1) Standing Strong for Cersei as King’s Landing Faced Collapse

Jaime Lannister's allegiance to Cersei was put to the test during the Siege of King's Landing. Although he was held captive by the Stark army, he never faltered in his allegiance to her. His love for his sister and lover compelled him to protect her reign, even when the city was being destroyed. The fight was a turning point for Jaime, demonstrating that he would risk his life to save Cersei. This blind loyalty, driven by his conviction of her authority, also strengthened the toxic but irreversible bond between them. His behavior highlighted the intensity of his familial connections despite the turmoil surrounding them.
2) Risking Everything Just to Be With Her Again

In Season 2, in the Battle of Blackwater, Jaime proves his allegiance to Cersei through his behavior, despite being a captive. He might have taken freedom or looked for a way out, but he just remains very much concerned about the safety of Cersei. Even when in captivity, he assures her of coming back to her amidst all the turmoil. This absolute devotion shows that Jaime's fidelity to Cersei is not simply about political partnership; it is fundamentally personal. Cersei may be remote and concentrated on keeping her children alive, but Jaime's dedication never wavers, evidencing his faith that his right position is alongside her.
3) Coming Back Broken, but Only Wanting Her

Jaime's return to King's Landing at the end of Season 3 is a stunning demonstration of his unshakeable commitment to Cersei. Even after he's been subjected to the terrors of captivity and the physical bruising of serving as a captive, his overriding concern on leaving captivity is getting back to her. Through everything that happens at the hands of the Starks, Jaime's unflappable commitment to Cersei continues to be his most compelling drive. His reunion with her is an important moment of vulnerability, but one that also points up the unhealthy codependency between the two of them. For Jaime, nothing could break the emotional and psychological connection with his sister.
4) Pushing Away Brienne to Stay Loyal to Cersei

Jaime Lannister's violent treatment of Brienne of Tarth on their travels together is another indication of his blind loyalty to Cersei. Despite the fact that Brienne gives him an opportunity for redemption and even forms a bond with him over common experiences, Jaime is steadfastly loyal to his sister. His callous words and deeds towards her are motivated by the fact that he can never betray Cersei, even if it means losing kindness or morality. This act highlights how far Jaime is stuck in his loyalty to Cersei, even if it goes against personal development or the possibility of honor bringing him deeper into moral gray areas.
5) Being a Pawn in Cersei’s Ruthless Power Games

Jaime's involvement in the facilitation of Cersei's political machinations in Season 4 is a demonstration of his blind loyalty, even as Cersei walks a precarious tightrope of manipulation. She employs Jaime as an instrument of her will, and he easily falls into her plans without considering the ethicality of their actions. For instance, Jaime is drawn into Cersei's plan to eliminate threats and shore up power for her house at the expense of the greater good. His blind allegiance makes him an accomplice to her brutal actions, showing how far he is willing to go to support her vision of power, even if it means sacrificing his own integrity in the process.
6) A Twisted Moment That Showed Obsession Over Morality

In Jaime raping Cersei in the Sept, his devotion to her becomes an extreme, disturbing thing. Though this is an extremely unnerving moment and a turning point for the character, it's also possible to realize Jaime is doing this because he feels he always needs to prioritize Cersei's needs above all else. His need to have and keep her drives him to behave in this ghastly manner, illustrating his blind love but also his intense psychological distress. This sequence illustrates how his devotion to Cersei has turned poisonous, warping his moral framework and impairing his judgment.
7) Challenging Religion to Rescue His Queen

Cersei is imprisoned by the Faith Militant in Season 6, which leads Jaime to new heights of devotion toward his sister. He arranges the escape for her, although he knows how bad it will be morally and politically. He does not care; he is just so blind to see. Jaime, even when Cersei's behavior becomes more erratic, is determinedly by her side. He disowns the High Sparrow and the Faith for her; he even risks his honor and reputation for her. That is, Jaime now becomes Cersei's enabler- he does not see himself as a protector of the realm because he considers himself a servant to all of Cersei's whims, leaving aside the costs to his risks.
8) Backing Her Bloody Reign Without Hesitation

During one of his darkest hours, Jaime assisted in killing the heads of House Tyrell, Mace and Margaery, under orders from Cersei. It is here that his loyalty to her vision of control and power shows even the depths of his personal integrity. Now, though Jaime begins to see some consequences of Cersei's ruthless behavior, he continues to follow her orders in his blind loyalty. This brutal act shows just how embroiled Jaime is in Cersei's manipulations and how far he will go to compromise everything-including his moral compass-in support of her rule.
9) Standing by Her While the World Turned Against Her

After the Battle of the Bastards, Jaime remains with Cersei despite the changing world around them. With the ascension of Daenerys Targaryen, Jaime's allegiance to Cersei keeps him oblivious to the danger she represents. He stands up for her behavior, not paying attention to the political realignments and the danger that she now faces. His blind loyalty still obfuscates his judgment, and though others question her increasing madness, Jaime holds firm in his conviction that she is the rightful queen. His stand on Cersei indicates his inability to differentiate between his love for her and his responsibility to the realm, illustrating the perils of blind loyalty.
10) Choosing to Die With Her Instead of Living Without Her

Jaime's last scene in Season 8 provides the payoff of his blind devotion to Cersei. Even as everything around them unravels, he decides to return to Cersei in King's Landing despite knowing the risk. Eventually, Jaime is killed along with Cersei in the Red Keep, demonstrating that his devotion to her is even stronger than his redemption. His choice shows the intricacy of their relationship in which love, devotion, and common history made him choose to give up his dignity and his chance at a good future.
