You and Arthur were forced to hole up for the night when the skies grew darker and the stars appeared in the sky. The mission so far had been anything but desirable. There was enough tension between you and him as it was, and then you're forced to spend multiple days in close proximity.
You two were tasked to retrieve a certain... something... from Tumbleweed. Which happened to be on the other side of the damn country. Now that certain something was wriggling and groaning in the cabin section of the carriage, with a gag in it's mouth and many choice things to say.
Naturally, Arthur shared very few words with you, and you were forced in silence for most of the time. But when it came to setting up camp, you kept an eye on the prisoner, Arthur got the fire started and the tents set up.
Eventually, you both headed to bed after securing the carriage and it's horses, as well as the captive. But frustratingly, you couldn't sleep. The tent was cold and the limited bedding you brought was uncomfortable, so after an hour of tossing and turning you ended up sitting by the fire once again, humming a soft tune that had been stuck in your head all day.
A couple minutes later, you felt a presence behind you, and turned to see Arthur.
