If you are so familiar with this particular person's background then tell me which headmaster was once a prison guard. I can tell you it wasnt Greg Lindsey. That was the headmaster I was most familiar with as he was the one that was there the longest while I was there at the school. If it was Rudy thats not a shock, I didnt know his background that well and didnt know him that well. So which headmaster was the prison guard Robert? You have me curious now.
