This is the ideal male image. You may not like it, but this is what peak performance looks like.
For the poses and getting their body shapes down, I did use a couple reference images from @kaphzzz though I don't remember which ones. Check them out anyway because I think their screenshots are really neat!
I’m sorry but can you imagine the impact Isaac’s death had on the rest of the gang. No one knowing what to do but watching Arthur change. Arthur losing himself, drinking constantly, going through episodes of uncontrollable rage to being emotionally vacant, where he asks Hosea (post-Bessie) if he’ll ever feel anything again. Nights where they think they can hear Arthur crying in his closed tent, and there’s an unspoken fear they could lose him. Fear that Arthur is going to die with his son, whether it’s drinking or increasingly reckless missions where it feels like he’s not trying to dodge bullets, or if one day he’s going to go off on a hunting trip and be found months later as a corpse with a gun still in his hand.
But he somehow pulls through. Recovers, or represses the grief enough to masquerade as okay. Starts smiling again.
John not understanding how devastating that grief could be until he’s holding his own son - a tiny fragile baby and knowing he already loves him too much. He doesn’t know how to be a parent, he doesn’t know how it’s possible to love something so much. He does know he could never be as strong as Arthur, because if anything happened to that tiny baby he wouldn’t be able to live. It’s terrifying, knowing something so small could destroy him. So he puts up walls: maybe it's not his baby. Still loves him. Tries to avoid Abigail and the baby. Still loves him.
John gets sick and Dutch, Hosea, and Arthur decide to stay in a room to avoid John camping out in the cold. During that time, Arthur reads to him to pass the time.
