S2E9 · Blackwater

Complete story — includes the ending

Stannis's fleet assaults King's Landing. Sansa plays along, trying to manipulate Joffrey into leading the attack himself (hoping to get him killed), but Joffrey proves too afraid to fight. Leading the defense, Tyrion destroys most of Stannis's fleet with wildfire, including Davos's ship; however, a significant force still manages to attack the castle. The Hound, overcome by his fear of fire, denounces Joffrey and deserts the battlefield. Joffrey retreats in fear as Tyrion rallies the Gold Cloaks into fighting with him. Stannis's forces enter the castle, but Tyrion leads his men behind them and mounts a rearguard attack. Cersei goes to the throne room with Tommen, intending to commit suicide rather than be captured. Tyrion is betrayed and wounded by one of the Kingsguard, Mandon Moore, but saved by his squire, Podrick. The Hound offers to take Sansa to Winterfell, but she is still scared of him and refuses. Tywin and Loras arrive with a combined Lannister–Tyrell army at the last minute to save the city, but Stannis escapes.
