“I keep remembering the Stark words. Winter has come, Father. For me. For me. Robb must fight the Greyjoys now as well as the Lannisters, and for what? For a gold hat and an iron chair? Surely the land has bled enough. I want my girls back, I want Robb to lay down his sword and pick some homely daughter of Walder Frey to make him happy and give him sons. I want Bran and Rickon back, I want …” Catelyn hung her head. “I want,” she said once more, and then her words were gone.
I always thought, in regards to the stability of his kingdom, Robbs betrothal to Roslin Frey was, in the long run the best thing that could have happened to him. After the Tullys, the Frey probably have a good chance of being the strongest Riverlands house, and they control the border between the two parts of his kingdom, therefore tying them both together. But the impression I get is that most fans think Robb's hand was "wasted" on Roslin. Am I missing something?
