Jamie poses as an obnoxious guest star on Off Centre, intending all along to ""X"" the show's star, Sean Maguire. The tables get turned, however, when Sean recognizes Jamie from a JKX promo--and proceeds to ""X"" him! Sean not only ""X-ed"" Jamie--the first time Jamie ever got ""X-ed""--but he ""X-ed"" his co-stars as well, who were all in on Jamie's prank and didn't know that Sean had figured Jamie out!
