EDIT: I'm actually pretty certain that Omar Sy will not be a member of the X-Men since I don't see him saying much given that his English is so poor, so I see him as a silent henchman of Magneto's. I also have a feeling that Blink is a substitute for Azazel since Flemying doesn't want to return. It could be one of the many rewrites done to the script.
Flemyng never said he didn't want to return. He said he was never asked and was 'gutted' about it.
