I just don’t see what the point would be of making a character who is already miserable even more miserable. We’ve already seen him go through the loss of the two people he loved. We’ve seen him dealing with the pain and guilt for centuries. If we were to see him experience yet another loss there wouldn’t be too much character development, I think. Something has to change to keep his story interesting and change the dynamics a bit. The writers can’t make him go through the same type of situation over and over again. That’s not good writing in my opinion.
