"There's nothing that can be done about it." James says it in a resigned tone of exhaustion, though he doesn't actually protest the demand. He wipes the blood from his hand onto a cleaner spot on his coat--the whole thing is going to need washing, so who cares--and then carefully shrugs off Prior's coat before reaching up to one-handedly unbutton his greatcoat.

"They're old, but have reopened and won't heal." Not until the scurvy is dealt with anyway, which he should probably explain, but his thoughts are going hazy again and he mostly has to concentrate on staying upright.
