So I was wondering why there are so many unanswered questions about Neinhart. Even after his defeat, he stayed a mystery. There are some characteristics which weren't explained about him.
1). Why does he refuse to obey Zeref's orders?
As you see, Neinhart didn't appear when Zeref ordered the Spriggans to come together. Also, Zeref didn't seem to care about it all.
2). Why isn't he a teamplayer?
He refused to work together with Dimaria and Wahl. Instead, he stayed at the ship doing nothing.
3). Does he have a connection with Ikaruga?
When he summoned Ikagura against Erza, he literally said "
my beautiful historia".
4). Why does he rate himself above the other Spriggans?
Neinhart made it sound like Wahl and Dimaria didn't reached anything at all, just as he expected. It seems like he ranks himself above them.
At some point, I don't know if I actually like the way how he is portrayed as a mystery or not..
