Well, I happen to think that Julia's first love was always her music (she was that moony artsy type like that) and Caraway second. I mean, I adore Laguna, but I figured it was more just a brief "hey someone will talk about my music with me!" and less omgtruelove. And it bothers me that Caraway is always painted with such a negative brush.
Besides, he wouldn't have spoiled Rinoa and been completely scary protective if he didn't love his wife and at least have SOME love in return. Logic. XD
