User blog comment:THE TERRIFYING TITANIA/Is there a connection between Master Mavis and Zeref?/@comment-117.197.190.26-20140512125713

According to my thinking,Igneel is the lumen histoire and Natsu is E.N.D.....Igneel cant stop him because Natsu somehow surpassed Igneel.....So Igneel asked Mavis Help,Mavis on condition somehow supressed the curse power of Natsu and turned him into a child(Maybe sacrificed her life to do so)...According to me The strongest demon(according to Zeref) is a dragon Named Natsu.....And next to him only Acnologia....When Natsu is unleashed Only Igneel can stop him by emotion....
