You talked about the Direwolf/Stark warg connections driving personality, but I think there are also foreshadowing connections to the fate and names of the Direwolves as well. Summer’s death literally was a sign that “Winter is here.” Robb and Rickon’s wolfies both died prior to their respective masters, and Jon’s wolf is named “Ghost”, probably not coincidental for a man that was raised from the dead. Sansa’s Lady was given a death sentence by Robert and Cersei’s behest, when Nymeria ran away…very symbolic of the death Sansa’s own idyllic picture of what being a lady in Westeros, kicking off her long arc of suffering and eventual hardening into what a lady really needs to be to survive in Westeros. Nymeria, like her namesake, the adventuring warrior queen, became her own queen of a the pack of Riverlands wolves and her rejection of Arya’s plea to come home mirrors Arya’s own rejection of her noblewoman fate and her adventurous arc thus far. But where else will the Nymeria parallels take Arya? She once asked Lady Crane “What’s west of Westeros”, I imagine her story ends with her sailing away from Westeros to found her own new city, in a place perhaps still unknown to the rest of the world.
