Benjamin
John gave it a few days-- he wanted Benjamin to have a chance to calm down and he wanted to regain some of his own physical strength for what was sure to be an exciting encounter.
Then he went looking. It wasn't hard to find the man, really. Someone died and he knew in his gut that Benjamin would be there. Maybe not close, but he'd be there. Overseeing his charges, or his duty, or maybe just using his failure to flog himself, but whatever it was he was doing he'd be there.
And he was.
John didn't say a word, just stopped beside the doctor and looked in the same direction. Watching someone being put in the ground, covered with dirt and their existence on this planet being covered up. He didn't 'cry but the lump in his throat temporarily prevented him from speaking.
