They left everything hanging; they didnt keep the couple together; they never showed her homeland; they never showed any of her "relatives"; they didnt conclude the connection with the wheat he brought with... etc. Usually when a story decides to end with one of those irritating endings where they leave things hanging and unknown, they do it in a very poetic way with a number of borderline definitive clues to lead to more than one conclusion. In this case though, they failed to do that. Anyways, thats just my opinion of course.
