Heh, more self-pimping, plainly you haven't read my island stories! The Other Side of the Island (http://www.anywherebeyond.com/stories/theotherside.html) and The Cherry Tree Ballad (http://www.anywherebeyond.com/stories/thecherry.html). The characterization is no longer "true" (they were written early last season, so stuff has changed since then) but I think they'll fit your requirements. :)
