Sigma jaunts towards the bird corpse until Roland picks it up, after which Sigma waits a few paces away. He had already trusted Roland with his life once before, and is content with letting him handle the knife. He watches him clean it quietly, behind solemn eyes. Roland doesn't need to finish that sentence.

"That might be prudent," Sigma agrees, if only from a competitive standpoint. Raising hell over the small things was a good way to get oneself killed - now that Roland mentions it, Sigma wonders what would have happened if someone had beat him to Roland. Would he have blown his own cover to help defend him? He certainly liked Roland, but that wasn't something he could answer from outside of the moment, not after he'd forced himself to kill Ruffnut. He'd faced a gauntlet of tests of his character in the most recent Arenas, and he did not expect it to stop after he petitioned out.

As for sharing a meal with someone else, that is something Sigma can easily accept, curiosity about Roland aside. He perks up at once: "I would be happy to, Mr. Deschain," he answers cheerfully. "If you might show me to where you were planning to set up camp, I can start a cooking fire," he offers - no matter how many Arena's he'd been in, Sigma had always found starting a fire to be a hassle, and wonders if Roland feels the same. Doing the chore for him might give Roland some time to cool off from his frustration.
