It sure sounds like it based on this season 9 casting notice:
MASON: Late 20's early 30's. He's a handsome charismatic charmer who savors life. He appreciates good food, loves fast cars and sees beauty in every woman. There isn't a detail in life that eludes his senses. He is a master of seduction... knowing what everyone wants and needs before they do. But don't let his magnetism fool you. There's more than meets the eye. His intelligence can't be matched. He outmaneuvers everyone in his path. Though he longs to find a home, that vulnerability can be twisted -- making him a force to be reckoned with."
