Ned refuses to participate in Robert’s plan to assassinate the pregnant Daenerys Targaryen and resigns as Robert’s Hand, angering him. Catelyn and Tyrion (whom she has taken as her prisoner) arrive at her sister Lysa’s home in the Eyrie. News of Tyrion’s capture reaches King’s Landing where Jaime Lannister, the Queen’s twin brother, demands answers from Ned. A vengeful Jaime orders Ned’s men killed and fights Ned until Jaime’s man stabs Ned in the leg from behind, leaving him wounded.
