User blog comment:Stone Roger/Natsu and Zeref have somekind of relation?/@comment-74.116.58.42-20140607160416

maybe natsu is from the past 400 yrs ago and failed to kill zeref for some unknown reason. then zeref becomes immortal forcing natsu to advance to the future because he is a dragon slayer he couldnt be restored to his original form because of his age and therefore became a child again.zeref knows this and stay on the island away from trouble until natsu meets him of tenroujima.zeref hoped natsu is able to kill him this time but natsu had lost his memories of his other life.zeref is disappointed and becomes evil again.i think igneel and natsu are friends from 400 yrs ago and therefore igneel didn't tell him about the past and gave him the scarf to protect him in case he encountered zeref. i think the day the dragons disappeared is the day acnologia awoke for his second coming the dragons feared his existence and disappeared to the mountains.
