User blog comment:Stone Roger/Natsu and Zeref have somekind of relation?/@comment-83.249.199.184-20141207132653

It makes a sense natsu being END. besides the reason why igneel couldnt kill END being that he would become  his son. Somehow END suffered memory loss or got sealed   such igneel decided to raise him as natsu dragneel and maybe natsu is he good version of END and somehow that scarf natsu has is to protect him from being his old  self.
