"You want to hunt all the wrong things." Zoro didn't trust yet that Noctis would curb his appetites once he got out there, and he didn't want to get into a dogfight about it. He was fine to let the boy out to run and stretch, but after he had a full belly, when the livestock would be in less danger. Maybe next month, they could out hunting together.
Zoro realized he'd advanced on the boy in response to the attention only after he'd actually started moving, pressing Noctis back in the direction of the white counters with the line of his body and a shove of his chest. Herding him into a corner. He'd already made his kill and eaten until he was full - it was his other instincts that were more dominant now. "So if you want to eat," he growled low, rubbing past Noctis' cheek to snap lightly at his ear lobe, "go ahead and eat."
His tone suggested Noctis might not have the chance if he waited.
