When Charles returned with Arthur, he was pissed off.

It was clear by the way his jaw was clenched, and he avoided everyone at camp - though it's not like he socialised with many of the gang members anyway.

Turns out, he was angry because a pair of men had decided to kill off a ton of bison. Knowing Charles, you knew it angered him to see things die needlessly.

Now, he sat on a crate by the fire, carefully working at some arrows with his brows knitted together in focus.
