A quick prediction on how the natsu vs gray will happened

AvatarGray will say something bad like i want to destroy the world for zeref or something like that and then it pisses natsu off then he accidentally killed avatargray.

Due to shock and denial end is released and fairytail gray (because the avatar is just an ice replica of himself) appears saying that you finally showed yourself end.
