If Rinoa and Squall arnt related--why do they make Julia (former lover of Laguna) Caraway's wife--its obvious that Caraway needs to be in the plot (assasination of the sorc) but why does he need to be married to Julia--is it simply to have Rinoa love the son of the man her mother loved and see the similarities in the song she wrote about Laguna--or are they related?
