Renly

“And his brothers?” Jon asked.
The armorer considered that a moment. “Robert was the true steel. Stannis is pure iron, black and hard and strong, yes, but brittle, the way iron gets. He’ll break before he bends. And Renly, that one, he’s copper, bright and shiny, pretty to look at but not worth all that much at the end of the day.”
And what metal is Robb? Jon did not ask. Noye was a Baratheon man; likely he thought Joffrey the lawful king and Robb a traitor. Among the brotherhood of the Night’s Watch, there was an unspoken pact never to probe too deeply into such matters. Men came to the Wall from all of the Seven Kingdoms, and old loves and loyalties were not easily forgotten, no matter how many oaths a man swore . . . as Jon himself had good reason to know. Even Sam—his father’s House was sworn to Highgarden, whose Lord Tyrell supported King Renly. Best not to talk of such things. The Night’s Watch took no sides. “Lord Mormont awaits us,” Jon said.
