What if, by some odd chance, Natsu is Zeref's brother, and the only one immune to his Death Magic. Or Natsu is "E.N.D". That would be a major twist. Enhanced Natsu Dragneel. Lol. I just wonder why Zeref is so interested in Natsu. I hope to see the Dragons soon. From what Future Rouge said, the world is sorta apocalyptic, and I wonder what happen to his Cat after the year is up, what kills him.
