the movie hinted at a Luna/Neville love in the offing considering Rowling never mentioned that, and, indeed, had them marrying other people. Though I've heard in the past that Rowling has to approve of any of the changes made in the film versions so she must have been okay with it. Maybe the liaison is meant to only be temporary. I wanted Luna and Neville to end up together so I was good with it. Actually, I wanted Luna and Harry to end up together but as it became apparent that was never going to happen, Luna and Neville became second choice.
