and on episode 52 if i'm not wrong, after the scene where Laxus was finally defeated, you see Igneel and Grandinee, they knew Zeref, because Grandinee said: by the way, Zeref is... . Zeref knew Natsu, on Tenroujima island he even recognized him, while Natsu didn't even know what he was. I don't know how, but he knew him so that he could 'stop' him, but he didn't seem to be ready for that. I think the dragons had to dissapear for some reason, and i guess Zeref is involved into that story. Grandinee said to Igneel they couldn't do anything but to believe in the power of the humans... .
