Jaime Lannister is portrayed by Nikolaj Coster-Waldau. Ser Jaime of House Lannister is a member of the Kingsguard and an exceptionally skilled swordsman. He is Cersei Lannister's twin brother and has carried on an incestuous love affair with her all his life, fathering all three of her living children. He is nicknamed "Kingslayer" for killing the previous King, Aerys II, whom he was sworn to protect. Jaime is captured by Robb Stark's army and held prisoner until he is released by Catelyn Stark and escorted back to King's Landing by Brienne of Tarth. On the road, his sword hand is severed and he reveals that he killed Aerys II to save the population of King's Landing, whom Aerys II was attempting to massacre with wildfire. Upon his return to King's Landing, he retakes his place in the Kingsguard and restarts his affair with Cersei. He travels to Dorne to rescue their daughter Myrcella, but cannot prevent her from being poisoned. After the Faith Militant gain control of the capital, Jaime is relieved of his Kingsguard duties and told to reclaim Riverrun with the Lannister army. Jaime is present at Cersei's crowning following their last child Tommen's suicide, but is later ambushed by Daenerys Targaryen, who has come to Westeros to stake a claim to the Iron Throne. After reuniting with Brienne and joining the effort to defeat the White Walkers, he returns to King's Landing to rescue Cersei from Daenerys' forces. The Lannister siblings die together when Daenerys' dragon, Drogon, destroys the Red Keep.
