User blog comment:IamJakuhoRaikoben/Chapter 464: Natsu vs Zeref, Review./@comment-24546844-20151130220956

Don't know... I've read this twice and both times it felt underwhelming for something that's supposed to be a decoy final fight (because we know Zeref isn't going down his easily). So the power is just something Igneel left inside him? And all it does is increase the power of his flames? Definetly not enought to kill him IMO. I too don't get Zeref's reasoing but I guess it's something like a power that transcend death, Igneel's flowing through Natsu even after his death (just like Obito's BS sharingan transfer), is the counter for a power that ignores it or something like that. Also, does that mean that Natsu's power will drop to a less OP level after this fight?

There were three things that interested me though:
 * The first one is that Zeref was smiling all the time thorugh the fight. Maybe be it's to show that he's proud of his brother's growth.
 * The second is that this power-up opens the oportunity for the other DS having a similar power, though weaker as they didn't train to master it like Natsu.
 * Like everyone else, I'm surprised that Zeref knew Layla though like I've stated before, I don't like that Layla have conections to the main events of the series but, as she does I'd rather she be related to Acnologia and the dragons instead of Zeref.

I don't feel like speculating who Anna is, but if I'm to give it a shot it is... Acnologia's true name! But seriously, maybe Brandish's/Laya's mother/sister, or something ike that. We surelly will know something important next chapter, with a title like that. Anyway, can't wait till Zeref sees himself unscathered by the attack soon.
