As I already answered in the prediction blog, people only got scared after the actually looked at Jiemma.

If they were afraid of an aura they felt, there would have been no need to look at him or for that one guy calling out "Look out, it's Sabertooth' Master".

The people got scared by his dark expression combined with his reputation.

As to the discussion itself, I just realized something. E.N.D. looks like an abbrevation and it contains Natsu's initials. So if the theory, as unlikely as it is, should proof true in some way, the N.D. might stand for Natsu Dragneel. No idea what the E. might be though.

But this is just idle musing. As I stated before I really don't think Natsu is E.N.D.
