title: List of Game of Thrones characters
text: Jaime Lannister ( season 1 -- present ) portrayed by Nikolaj Coster - Waldau . Ser Jaime Lannister of House Lannister is a member of the Kingsguard and an exceptionally skilled swordsman . He is the Queen 's twin brother and has carried on an incestuous love affair with her all his life , fathering all three of her living children . He truly does love his sister and will do anything , no matter how rash , to stay close to her . He is nicknamed `` Kingslayer '' for killing the previous King , Aerys II , whom he was sworn to protect . He was allowed to keep his post in the current Kingsguard as he and his influential father helped Robert win the war , but no one feels he deserves this post , which frustrates Jaime . Despite Eddard Stark 's animosity against him for forsaking his oath to protect the King during Robert 's Rebellion , Jaime has great respect for Eddard , whom he considers a great warrior and his equal . Unlike his father and sister , Jaime cares deeply about his younger brother Tyrion . In Season 2 , Catelyn releases and sends Jaime to King 's Landing under Brienne of Tarth 's watch in exchange for a pledge to send her daughters home . On the journey , they are captured by the violent Locke , a man - at - arms under Roose Bolton , a Northern Lord . On their way to Harrenhal , now held by Bolton , the lowborn Locke cuts off Jaime 's sword hand to taunt his position and privilege . Jaime survives and is allowed to depart Harrenhal on condition that he acquits Bolton from any guilt . During his time in Harrenhal , Jaime reveals to Brienne on why he killed King Aerys II . Once freed , Jaime travels to King 's Landing with Brienne and disgraced Maester Qyburn , given by Bolton to tend to his injury , in tow . At the end of Season 3 , they arrive at the gates and Jaime reunites with Cersei . In season 4 , Jaime is fitted with a golden prosthetic hand and given a new sword , and is trained by Bronn in fencing with his left hand . Jaime is one of the few people in King 's Landing who believe in Tyrion 's innocence in killing Joffrey , and does his best to comfort his younger brother , while outright refusing Cersei 's order to kill Tyrion before his trial . When Tyrion is sentenced to death , Jaime frees Tyrion from captivity and arranges for him to be smuggled to Essos with Varys 's help . Jaime tells Cersei that he will travel to Dorne and bring Myrcella back . Myrcella says that she likes it in Dorne and does n't want to go back to King 's Landing . However , she eventually leaves with her uncle and Trystane , after Doran bargains to have his son take his seat on the Small Council . On the journey home , Jaime reveals his incestuous relationship to Cersei to their daughter , who then reveals she knows and is glad that Jaime is her father and hugs him , but moments later Myrcella collapses from poison and dies . In season 6 , Jaime returns to King 's Landing with Myrcella 's body and sends Doran a letter requesting the heads of Ellaria , Obara , Nymeria and Tyene , but later hears that both Doran and Trystane were killed by the Sands . In response to Cersei 's humiliation by the Faith Militant , Jaime ponders murdering the High Sparrow and marching on the Great Sept of Baelor with the army of House Tyrell to forcibly rescue Margaery from custody . He is foiled , however , when Tommen declares an allegiance between the Faith and the Crown , and dismisses Jaime from the Kingsguard , clearly on the High Sparrow 's orders . Jaime is later sent to the Riverlands with Bronn to oversee the surrender of Riverrun . He parleys with Brynden `` The Blackfish '' Tully , to no avail , and then falsely threatens Edmure Tully with the murder of his baby son if he does not get his men to surrender the castle . The castle eventually falls to the Lannisters and Freys . Jaime briefly crosses paths with Brienne and Podrick , but allows them to leave peacefully . He returns to King 's Landing shortly after the Great Sept 's destruction , and enters the Red Keep to see Cersei being crowned Queen . In Season 7 he commands the Lannister army , capturing Highgarden but suffering defeat when ambushed by Daenerys ' Dothraki forces and dragons . He clashes with Cersei over the threat from the Army of the Dead , and when she breaks her word over sending military support he leaves her and rides north alone .
