Before I got tot he final page, I thought the one who took E.N.D'S Book was E.N.D himself. That would have been epic. There are a few things that bug me about the dragons: 1) Where was that rocky terrain Igneel was seen in? A manifestation of Natsu's mind? 2) When Grandeeny talked to him, how the hell did she get in? And if they were talking in Natsu's mind, wouldnt ge have heard it? 3) How come Grandeeny, if she was in Wendy, not just transfer the knowledge instead of mind skyping (get it?) with Porlyusica?

Now I understand why Natsu and Gajeel couldn't escape Feeds runes. Now before ressurecting E.N.D and for some reason, I pray the Dragons and their children fight him, I hope Zeref explains how he and Natsu know each other.
