It might sound unfair, but I tend to believe Master more, he is
after all my entree student. Unless you can prove otherwise. And I
think the only way is a face to face date...ermm I mean
interview.
Let's say Master is credible... then Fairlady and Stellazio are
definitely credible too. 
If the date erm.. I mean the interview is to take place, you
might want to provide the details.
