The third of Lord Eddard’s legitimate children, Arya is the very picture of a tomboy, spending her time among the servants and their children, asking questions and playing games and avoiding all kind of of more lady-like pursuits. She exasperates her mother Lady Catelyn, who sometimes wishes she was more like her elder sister Sansa; it’s no surprise that the sisters do not get along. Closest with her bastard half-brother Jon, like him she’s the only other child of Eddard Stark who takes after him with her brown hair and grey eyes.
On the show, Arya started the show as being aged 11, whereas in the novels she starts at 9 years old.
Arya, Gendry, and Hot Pie come across the brotherhood without banners in the form of a company led by Thoros of Myr and Anguy the Archer. They are made to go with them to Lord Beric, who leads them. Along the way, they are joined by another group of men who reveal they have captured the Hound. At the hollow hill where the brotherhood hides, Lord Beric meets Arya and explains that he will see her returned to her family in time. But first he judges the Hound to trial by combat. Arya witnesses the Hound seem to kill Beric, only for him to rise again after Thoros prays over him and beseeches the Lord of Light to restore him. Arya learns that this has not been the first time Beric died and came again. Matters grow more troubled when the red priestess, Melisandre, convinces Beric to give over Gendry to her, as she is aware that he is Robert Baratheon’s bastard. Despite Arya’s protests, they trade Gendry away for sacks of gold with which they can continue to fight for justice and protect the smallfolk. Despite the promises, her family never comes nearer as the brotherhood prioritize fighting raiders and reavers. In the end, Arya runs, only to be captured by the Hound. He takes her to the Twins in time to witness the chaos during the Red Wedding, the death of Grey Wind, and the display of Robb’s body. The Hound carries Arya away after stopping her from running into the castle. Later, they pass several soldiers making light of the murder of her family: Arya pretends to be a beggar and then personally stabs to death one of the men, while the Hound kills the others.
