I was thinking,has Gray along the lines figured out that Natsu is END?He shoulndn't be mentioning the Book especialy if not.If he found Natsus plan stupid in general he would say"I doubt he suceeds because Zeref won't be alone,the Shields probably are there too".And if Zeref unseals the book of END one aditional demon is trouble for everyone exept probably Gray.In Natsu's case however it means Ishgar and Fairy Tail suffers a loss by converting an ally to an enemy.
