Jaime went to the throne room. On the way, he came across Rossart, who was dressed as a common soldier and hurrying to a postern gate. Jaime attacked him, and while Rossart tried to defend himself, he stood no chance against the experienced knight, who gutted Rossart without mercy. Jaime then slipped into the throne room through the king's door, finding Aerys alone pacing through the room. When the King saw the blood on Jaime's sword, he demanded to know whether it was Lord Tywin's, renewing his command that Jaime should bring him his father's head, otherwise Jaime would burn with all the other traitors. He told Jaime that Rossart was on his way to give the enemies a warm welcome, asking again whose blood was on Jaime's sword. Jaime answered that it was Rossart's. The King became scared, his mouth dropping open in shock. Aerys lost control of his bowels, soiling himself. He turned and ran towards the Iron Throne. Jaime seized Aerys and hauled him bodily off the steps. The Mad King squealed like a pig as Jaime killed him with a single slash across the throat, thereby preventing him from giving the command to burn the city to some other pyromancer.
