CNBA, that logic is flawed because all dragon slayers smell just like dragons, and Acnologia has no problem finding them. Dragon Slayers and dragons have always an integral, major part of the story, and though this major plot point is side-lined, it's extremely important that Acnologia couldn't smell or detect Irene's dragon nature. The next chapter gives me hope that it will be fixed judging by the title, but if a development cleaves holes in the story after it is given, then it's not particularly a good development. Readers shouldn't have to fill holes themselves, and the author shouldn't have to backtrack and retcon, either.
