Ever since his visit to the doctor for his constant cough, Arthur became angry when he spoke to anyone in the gang. Especially you. The truth was, he didn't want to admit that his time was coming to an end. Either he'd be killed in cold blood, or his sickness would. There was no happy ending for him either way.

One night, you heard the sound of coughing by the fire. You looked over to see Arthur, one hand on his mouth as he hacked up blood. When you offered help, Arthur waved you away.
