TL; DR - Arya aprenderá a ser dama e será casada para o casamento.
No entanto, a verdadeira questão é por que alguns deles ficaram em Winterfell. Normalmente, como um emprego no mundo moderno, quando você assume um novo emprego em uma nova cidade, sua família viaja com você.
Nós vemos isso com duas mãos anteriores; Jon Arryn leva sua esposa Lysa e seu filho Robert para Porto Real antes de Lysa fugir após a morte de Jon, e com Tywin Lannister que levou Cersei e Jaime à corte apenas para sair com Cersei depois que Jaime se juntou à Guarda Real.
No entanto, os Stark são diferentes, os Starks seguem os "Antigos Caminhos" e têm tradições pelas quais eles vivem. Uma dessas tradições é que "sempre deve haver um Stark em Winterfell". Tipicamente, isso significava o atual patriarca da casa, mas nos tempos em que o lorde era chamado, alguém deveria preencher seu lugar. Os livros nos oferecem mais detalhes nessa interação, e lembre-se que Ned não queria que o trabalho fosse Catelyn e Luwin, que o convenceram a fazê-lo.
"The Others take both of you," Ned muttered darkly. He turned away from them and went to the window. She did not speak, nor did the maester. They waited, quiet, while Eddard Stark said a silent farewell to the home he loved. When he turned away from the window at last, his voice was tired and full of melancholy, and moisture glittered faintly in the corners of his eyes. "My father went south once, to answer the summons of a king. He never came home again."
"A different time," Maester Luwin said. "A different king."
"Yes," Ned said dully. He seated himself in a chair by the hearth. "Catelyn, you shall stay here in Winterfell."
His words were like an icy draft through her heart. "No," she said, suddenly afraid. Was this to be her punishment? Never to see his face again, nor to feel his arms around her?
"Yes," Ned said, in words that would brook no argument. "You must govern the north in my stead, while I run Robert's errands. There must always be a Stark in Winterfell. Robb is fourteen. Soon enough, he will be a man grown. He must learn to rule, and I will not be here for him. Make him part of your councils. He must be ready when his time comes."
"Gods will, not for many years," Maester Luwin murmured.
"Maester Luwin, I trust you as I would my own blood. Give my wife your voice in all things great and small. Teach my son the things he needs to know. Winter is coming."
Maester Luwin nodded gravely. Then silence fell, until Catelyn found her courage and asked the question whose answer she most dreaded. "What of the other children?"
Ned stood, and took her in his arms, and held her face close to his. "Rickon is very young," he said gently. "He should stay here with you and Robb. The others I would take with me."
"I could not bear it," Catelyn said, trembling.
"You must," he said. "Sansa must wed Joffrey, that is clear now, we must give them no grounds to suspect our devotion. And it is past time that Arya learned the ways of a southron court. In a few years she will be of an age to marry too."
Sansa would shine in the south, Catelyn thought to herself, and the gods knew that Arya needed refinement. Reluctantly, she let go of them in her heart. But not Bran. Never Bran. "Yes," she said, "but please, Ned, for the love you bear me, let Bran remain here at Winterfell. He is only seven."
"I was eight when my father sent me to foster at the Eyrie," Ned said. "Ser Rodrik tells me there is bad feeling between Robb and Prince Joffrey. That is not healthy. Bran can bridge that distance. He is a sweet boy, quick to laugh, easy to love. Let him grow up with the young princes, let him become their friend as Robert became mine. Our House will be the safer for it."
