Here is the Banner no. 4 of 'Harry Potter and the Deathly Hallows - Part 2' and it's Neville Longbottom this time. Holding the Gryffindor sword. This is Neville's first banner in all 'Harry Potter' films.
I know he deserves to have his own banner cause he will shine in this film. He carries dead bodies. He will kill Death Eaters by destroying the viaduct bridge. Love the Hogwarts Tower and Bridge background.
Among the 4 banners, this one is the most perfect but I like the Ron's banner more but this one is my 2nd.
