A Game of Thrones
"We're not friends," Jon said. He put a hand on Sam's broad shoulder. "We're brothers."
And so they were, he thought to himself after Sam had taken his leave. Robb and Bran and Rickon were his father's sons, and he loved them still, yet Jon knew that he had never truly been one of them. Catelyn Stark had seen to that. The grey walls of Winterfell might still haunt his dreams, but Castle Black was his life now, and his brothers were Sam and Grenn and Halder and Pyp and the other cast-outs who wore the black of the Night's Watch. (27 Jon 4.107-8)
"Whatever you may believe of me, Lady Stark, I promise you this – I never bet against my family." (32 Tyrion 4.112)
In this place, the crones of the dosh khaleen had decreed, all Dothraki were one blood, one khalasar, one herd. (37 Daenerys 4.39)
