User blog comment:Stone Roger/Natsu and Zeref have somekind of relation?/@comment-122.54.181.103-20130228020027

I think that natsu and zeref are brothers. Natsu is in the good side and zeref belongs to the opposite. Natsu and the other firt gen. dragon slayers maybe exist 400 yrs also and that explains why they cannot pass in freed's rune. And now what i am thinking is mavis and zeref must be somehow related. And i think igneel must be hiding somewhere cause he appears in the anime talking w/ that wisp(dota) like and saying he's son natsu, is already going overboard.
