As promised, JT attended the Marine Corps Ball Saturday in Richmond, Virginia with combat instructor Kelsey De Santis.  The wife of a Marine who attended said Justin "posed for pictures and seemed like a normal guy." Another attendee said, "Justin seemed to have a good time, and it was great to see him there."
