who kills tywin lannister in game of thrones
Tywin Lannister Tywin has the Stark ancestral sword Ice melted down into two swords, one of which he gives to Jaime, though he disowns him after Jaime refuses to resign from the Kingsguard to become Tywin's heir. When Tyrion is accused of poisoning Joffrey, Tywin asks Prince Oberyn Martell to serve as one of the judges in Tyrion's trial. Though Oberyn despises Tywin for ordering the death of his sister, niece and nephew during the sack of King's Landing, he agrees when Tywin offers him justice against their murderer, Ser Gregor Clegane. Tywin also presses Cersei to wed Loras in order to use House Tyrell's wealth to pay off the Crown's debts to the Iron Bank of Braavos, but is forced to back down when Cersei threatens to reveal her incestuous affair with Jaime. Tywin has an affair with the prostitute Shae, formerly Tyrion's mistress. Tyrion discovers this during his escape from King's Landing and strangles Shae before confronting Tywin on the privy. When Tyrion admits that he loved Shae, Tywin repeatedly dismisses her as a whore, prompting Tyrion to shoot him with a crossbow, killing him.
The Rains of Castamere Catelyn notices Roose Bolton wearing chainmail under his robes which confirms Catelyn's suspicions that they have been betrayed. Just as Walder signals his men to attack the Starks' men, Catelyn tries to warn Robb, but before he can react, Lothar repeatedly stabs the pregnant Talisa in the stomach, killing her and her unborn child. As he tries to draw his sword, Robb is shot by crossbows, and the massacre of his bannermen begins. Arya, having snuck past the gate, witnesses Frey men kill Stark soldiers and Robb's direwolf, Grey Wind. She is saved by the Hound, who knocks her unconscious and carries her out of the castle. Catelyn, although wounded by a crossbow bolt, holds Walder's young wife, Joyeuse, hostage with a knife and demands that Robb be allowed to leave. Walder refuses, and Roose Bolton stabs Robb in the heart, delivering Jaime's message from Harrenhal, "The Lannisters send their regards." Catelyn screams and kills Joyeuse in retaliation, before Frey's son Black Walder cuts Catelyn's throat.
