But there is a major flaw in that plothole, if Acnologia could smell Dragon Slayers from such a long distance even if Irene was far away, why hasn't Acnologia gone after Natsu and the others the moment they received DS magic or when the first time Natsu went DF. The only thing I can think of is that Acnologia was too arrogant to even care about such trivial things and would not bother since no one can best him.
