James has let her heal his hand. Well maybe "let her" is a little bit of a stretch. James didn’t move or acknowledge her at all. Even when she went to remove the picture from his hand, in order to clean away the blood. She was able to remove the scar, fixing his hand up as if nothing happened. Even though there was no physical hurt left, Lily could tell that was the least of his concerns. It broke Lilys’ heart. She’s never seen James so...empty. He’s been staring at the same spot for two hours, and every time Lily tries to look into his eyes she finds nothing. Lily doesn't know what to do. She doesn't understand what’s happened. She’s scared, scared that this is something James wont come back from. The thought alone is ridiculous, at first. He’s survived war, yet he’s never looked as destroyed as he does now. So yeah, Lily is scared.
