nej.
Det är inte i föreställningen, men i böckerna har Arya ett par wargdrömmar där hon ser genom Nymerias ögon, som väsentligen prowling skogarna om vad som starkt antydas vara Riverlands.
Från En storm av svärd II: Blod och guld (kapitel 65, Arya XII ):
By the time they found themselves in the foothills of the Mountains of the Moon, the rains had mostly stopped. Arya could see the sun and moon and stars, and it seemed to her that they were heading eastwards. "Where are we going?" she asked again.
This time the Hound answered her. "You have an aunt in the Eyrie. Might be she'll want to ransom your scrawny arse, though the gods know why. Once we find the high road, we can follow it all the way to the Bloody Gate.
Som det framgår av detta citat, har Arya och Hound vid den här tiden lämnat Riverlands bakom och flyttar mot Vale of Arryn. Omkring den tiden har Arya en mycket levande dröm:
That night she went to sleep thinking of her mother, and wondering if she should kill the Hound in his sleep and rescue Lady Catelyn herself. When she closed her eyes she saw her mother's face against the back of her eyelids. She's so close I could almost smell her ...
... and then she could smell her. The scent was faint beneath the other smells, beneath moss and mud and water, and the stench of rotting reeds and rotting men. She padded slowly through the soft ground to the river's edge, lapped up a drink, then lifted her head to sniff. The sky was grey and thick with cloud, the river green and full of floating things. Dead men clogged the shallows, some still moving as the water pushed them, others washed up on the banks. Her brothers and sisters swarmed around them, tearing at the ripe flesh.
Medan inte identifieras med namn, menar den flod som nämns där, att den är Greenfork (floden vid tvillingarna), tillbaka i Riverlands.
Från En dans med drakar II: Efter festen (kapitel 45, Blindflickan ):
She opened her eyes and stared up blind at the black that shrouded her, her dream already fading. So beautiful. She licked her lips, remembering. The bleating of the sheep, the terror in the shepherd's eyes, the sounds the dogs made as she killed them one by one, the snarling of her pack. Game had become scarcer since the snows began to fall, but last night they had feasted. Lamb and dog and mutton and the flesh of man. Some of her little grey cousins were afraid of men, even dead men, but not her. Meat was meat, and men were prey. She was the night wolf.
But only when she dreamed.
Här är det ännu mer uppenbart. Nymeria är fortfarande tillbaka i Westeros (där vintern sätter sig in) och medan den exakta regionen aldrig identifieras är hon säkerligen ingenstans nära Arya som befinner sig i Braavos vid den tiden.
Det finns också flera nämnder av en jätte wolfpack som terroriserar Riverlands.
Från En fest för kråkor (Kapitel 44, Jaime VII ):
The next day, Ser Dermot of the Rainwood returned to the castle, empty-handed. When asked what he'd found, he answered, "Wolves. Hundreds of bloody beggars." He'd lost two sentries to them. The wolves had come out of the dark to savage them. "Armed men in mail and boiled leather, and yet the beasts had no fear of them. Before he died, Jate said the pack was led by a she-wolf of monstrous size. A direwolf, to hear him tell it. [...]
"A ring of fires round your camp might keep them off," said Jaime, though he wondered. Could Ser Dermot's wolf be the same beast that had mauled Joffrey near the crossroads?
Den här gången är området tydligt identifierat: Jaime är vid Riverrun vid den tiden. Arya har under tiden lämnat Westeros och har tillbringat en del tid redan i Braavos.
Det verkar som om Nymeria var ganska kvar i det område där Arya lämnade henne tillbaka i The Thrones Game och gjorde det till sitt packs territorium. Det här är också där Arya möter det paket som nämns i ditt citat och där hon möter Nymeria under säsong 7.
