Lord Marcus Beaton

A British lord, Blair met in Europe and uses him to make Chuck jealous. Blair was unaware of his title when he pretended to be a college student from inconsistent colleges (Georgetown, Yale, Princeton, etc) by the name of James. After Blair points out his flaw as being somewhat 'boring' he drops the college boy act and confesses the truth about his title. Blair is astounded and continues her relationship with him, taking steps to impress him and unfortunately, his stepmother, who happens to be Nate's current love interest. In 'The Ex-Files' it was revealed that he was having an affair with his stepmother, Catherine Mason. They were caught by Vanessa who later told Blair and Blair threatened to tell people unless they left the country.
