rachel mason rachel mason is a fictional character not a real person and as such the qualifications are very much irrelevant to the article the article may wright including qualifications although notice none of the other articles on eastenders doctors list them is also irrelevant secondly she has only been referred to as rach on few occasions she is not credited as rach in anyway however in the case of other characters such as melissa ryan it is different she was referred to on a much wider scale as mel but her credited name is still melissa
