Arthur was possessive of you. Almost too possessive, to some people. He was always by your side, attached at the hip. People knew he was a dangerous, so they respected his wishes.

Unfortunately, Dutch wanted to talk to you. Alone. It wasn't anything malicious, but to Arthur, it felt like a personal attack. He was not happy when you told him. "Alone.. has he lost his damn mind?" Arthur grumbled in frustration, pacing in your shared tent. He was pissed, more than pissed even.
