The parasites nearby wore offended looks upon hearing him address her so casually. The goblins, meanwhile, seemed stunned by the fact that Ken had proclaimed himself to be a representative of the common people.
They hadn't exactly told him what to do in the meeting except being polite and cooperating with the envoys, since they thought of him as the spy Roshoka had planted in their midst. It was the only reasonable explanation behind the envoys' refusal to hold a meeting without Ken.
However, Ken's claim was a huge divergence from their planned routes of negotiations. When someone sitting in a meeting of aristocrats claimed to be representing the common folk, it easily changed the undercurrents. The fact that they didn't know Ken's real background was another volatile element, creating nothing but a headache for everyone in the meeting.
