Took me a while to find one near the very end, where Ketho, a Hainishman, member of the oldest sentient race in the universe, decided to risk his life with Shevefc on his return to Anarres:
"[Ketho] looked at him gravely, as if he was not sure what happiness was, and yet recognized or perhaps remembered it from afar. He stood beside Shevefc as if there was something he wanted to ask him. But he did not ask it “It will be early morning at Anarres Port,” he said at last, and took his leave, to get his things and meet Shevek at the launch port."
