how about at the end of this story it turn out to be that natsu is acnologia from past and another timeline, explains how zeref seem's to know alot about natsu and only reason why he helped acnologia to become dragon and the strongest is that he wanted to die already. but acnlogia lose his control, well he could have just let acnologia to kill him!! but im not mistaken zeref is tired of war/killing and want peace but how can he die and leave the loose acnologia? explain's why he said only natsu can kill him. but got disappointed after they meet and said that natsu is not ready. or maybe zeref is acnologia himself and as far as i know natsu is the strongest DS in this show. -One thing for sure, ONLY HIRO MASHIMA knows what comes next!!! :)
