Luc is definitely sort of just *around* (which has nothing to do with everyone else and 100% to do with my inability to play him). Luc and Ria's (continuing?) hookup's are definitely a highlight for him but we could totally talk about finding something else for them to do besides that!
Like with Nathan, Luc is totally around for giving all the advice! Even if he isn't a relationship kind of guy, he would listen to any concerns Nick had about his and Lita's relationships until the cows came home :-)
