You know what? He doesn't look anything like the portrait.
Well, that's ridiculous. He looks exactly like it.
No, he doesn't. The man in this portrait seems as though he's angry at someone. But Barnabas, my cousin that I met at the Old House, he seems more sad than angry. Seems as though he's remembering something that he's lost a long time ago. Maybe that's when I thought he was a ghost. He seemed as though he was haunting the rooms instead of just walking through them.
