User blog comment:JohnnyN64/END/Natsu theories don't add up/@comment-24.252.59.97-20141107134204

The older than 80 years old thing with the Fried's runes during the fighting festival was explained when Igneel came out of Natsu's body. We can only assume that's the same case with Wendy and Gajeel's dragons. Of course, a person harboring a 400+ year old dragon couldn't pass the runes. I'm not sure how to explain the mention on END being created for the sole purpose of killing Zeref and Zeref actually saying on Tenrou Island that Natsu is the only one who can destroy him. Lets not forget the obvious familiarity that Zeref has with Natsu. We're missing some vital pieces to the puzzle
