User blog comment:Stone Roger/Natsu and Zeref have somekind of relation?/@comment-176.253.209.253-20131109171104

Maybe Natsu is actually evil and Igneel's scarf is the only thing keeping him from becoming evil like maybe it absorbs the evil magic and Zeref knows Natsu when he was a kid and Igneel took Natsu in his care so he can change Natsu and make him good and when he thought Natsu was turning to the light he left and gave him a scarf which absorbs dark magic
