User blog comment:Stone Roger/Natsu and Zeref have somekind of relation?/@comment-122.54.181.103-20130228020027/@comment-99.240.136.178-20130312142231

no, that doesn't work, because zeref is a couple hundred years old where as natsu is 17(but should have been 24) so i think that zeref IS Natsu's dad and thats why he said" I can finally see you all grown up" so maybe his mother was Edo grandine (thats why the pink hair)
