User blog comment:Stone Roger/Natsu and Zeref have somekind of relation?/@comment-76.121.234.236-20140104093459

I'm gonna say this, but I think Natsu have some random hatred or grudge on Zeref, like the first time that Natsu met Zeref, he punch him out of pure rage(hatred). Like that isn't normal. Like read/watch the Tenroujima arc and read the Tartarus arc. there some hint(spoiler) that Natsu isn't being normal due to some random rage/hatred
