In King's Landing, Ned finds Robert's eldest brother Stannis Baratheon left the city after Jon Arryn's death for his island of Dragonstone. Ned begins to investigate into Jon Arryn's affairs, which leads him to visiting locations where Jon Arryn visited with Stannis - including places where Robert's bastard children are found. On the way back from one such place, Ned and his soldiers are waylaid by Jaime Lannister, who demands Tyrion's return, and when he does not get what he wants he orders Ned's men be killed - in the ensuing skirmish, Ned is crippled in one leg when his horse collapses on top of him.
