At the time of the cruise crash, Kimberly and Shirley Linton were in the midst of an argument. Shirley was working on the cruise as part of the staff, and had discovered that Kim was on the cruise just to rub her success in her face. The two sisters have never gotten along--Shirley always wanted to be a professional athlete, but an injury in her childhood caused her dream to drastically veer off-course, whereas Kimberly's ambitions have been very successful. #usisland #usislandchallenge #sisters
