Just an FYI, later games retcon Rolande's name to Lauren for some reason... :\
Leon set out to develop his strength further by entering the third tournament, during which he was constantly haunted by remorse for losing Rolande to the desert. During the tournament, Jann Lee caught up to him to challenge his strength.
After the fight, Leon returned to the desert, and the oasis where he had buried Rolande, and was greeted by a hallucination, or possibly the ghost, of his lover. This vision of Rolande gave Leon a desert flower, before disappearing again, maybe in a way of telling him that he had proved himself, and he could moved on with his life.
