Neville

I have not posted much, but I want to ask a question regarding Neville. What will his role be in Deathly Hallows? I am one of those people loving tha chiastic structure theory, in which book 1 and 7, 2 and 6 and 3 and 5 are pairs, while book 4 is the turning point, containing elements from all. We clearly find similarities between 3 and 5, both being kind of inward and depressing, fleshed out in book five, Harry´s “Dark Night of the Soul.” Books 2 and 6 both have the concept of the Horcrux, but fleshed out in book 6.

So, if book 1 and 7 are similar, could it be that Neville´s bravery will mirror his bravery in book one, where he earned Gryffindor the House cup? Can he be the one that turns it around in the war?
