Dr Vickers
From BRGS Wiki
Dr Vickers was a stand-in for Miss Hartley and was considered by many to be Boris Johnson or Peter Pettigrew due to his almost identical appearance to them both. He was usually either very happy or very cross. Mostly the former. Had an Xbox 360, and the 120 Year 9 students he taught tried, unsuccessfully, every lesson to get his gamer tag (every form does this to teachers with Xbox Live). He left the school in 2009 upon Miss Hartley's return.
