User blog comment:Bunnyllove/Have Natsu and Zeref meet before?/@comment-24066070-20131111101402

Going by the fact Zeref knew Natsu's name and immediately recognized him, I guess it's safe to say they have some connection. Would be cool imho if this connection involves Igneel and E.N.D.

However, the downside of this connection is that now it is pretty much guaranteed Natsu will be the one to beat/kill/change Zeref and not some other char like Mavis or a God of Ishval.

I just hope the eventual fight between Natsu and Zeref will be done nicely and not something like Zeref spamming his death aura while Natsu copies his scarf's protection to every other piece of clothing he's wearing in order to resist Zeref's death aura. I wanna see Zeref use many different kinds of magic.

My preferred way of Zeref getting killed would be when Rufus shows up, copies Zeref's death aura with his memory make and finishes Zeref off with his own magic, but some dreams just aren't meant to be I guess.
