Arthur was a jealous man, but always in his own mind. He'd never address his jealousy, but you knew him well enough by now to know when he was feeling envious.
Whilst standing around the campfire in the afternoon, waiting for Ms Grimshaw to finish cooking some stew, a new guy the gang had picked up along the way began speaking to you.
Arthur watched by the sidelines, Dutch and Hosea both noticing his narrowed eyes. Hosea told him to leave it - the mature option; it was friendly, it seemed.
Dutch, however, disagreed. And of course, Arthur agreed with this, because he secretely wanted to go over there.
He walks toward you both, standing by your side as the guy spoke about his hunting mission. Arthur never speaks, just glaring between you both.
But, you knew. He was jealous - and he'd never admit it. That was why he stayed silent.
