For most of his time on the series, Greene's role was that of a mediator and occasional authority figure, and he was considered the main character of the series for the first eight seasons . Mark was also the only original character to die, and his death at the end of Season 8 marked one of the biggest turning points in the series . </P> <P> Mark Greene, an only child, was raised by his mother, Ruth, and father, David . David Greene served in the United States Navy, and thus the family moved frequently and lived all over the country, including: Jacksonville, Florida, Norfolk, Virginia, Corpus Christi, Texas, Washington D.C., Kings Bay, Georgia, and Hawaii, where they spent three years, David's longest assignment . Mark had a very strained relationship with his father, and was decidedly closer to his mother . He would often act out in an attempt to upset his father, and aimed his goals in the opposite of what his father wanted . Mark thought his father's Navy career mattered more to him than his family, only to later learn that David was on track to be an Admiral and turned down the chance in order to come home and help Mark with a bully . The most memorable time of his childhood was when his family was in Hawaii, a time he would later recreate with daughter Rachel during the last few weeks of his life . </P>
