its been pointed out before that arya is one of the few characters to react on page to all her family members deaths. this is especially significant for the starks because they’ve all been separated for so long and theres a lot of uncertainty regarding what has become of each of them. most of the time we don’t get to see their immediate reactions to news of the others alleged fates
A long time ago, she remembered her father saying that when the cold winds blow the lone wolf dies and the pack survives. He had it backwards. Arya, the lone wolf, still lived, but the wolves of the pack had been taken and slain and skinned. (affc)
theres a great deal of focus on family in arya’s storyline. this is because her identity arc and her pack are COMPLETELY dependent on each other. arya’s gradual loss of her identity is a direct response to each relationship that she loses to death or abandonment.
