It is a shame there will not be as much of Lupin as we ALL would like, especially the scene from the HBP book where they are sitting around the fire at Christmas at the Burrow and Harry talks with Lupin. I mean, Fleur is not in the film, so we know that scene will be OUT. I am guessing he maybe in the fighting at the end because he really isnt in HBP much except popping in and out of the Burrow.
