It guess Natsu's true identity will be revealed in this arc,what i mean is,the members of alvareth empire will impossible to defeat with his power as a dragon slayer and as we know since Zeref revived Natsu i the hopes that the latter will kill him;to defeat the alvareth empire,Natsu needs to use his "true power".
