FT has going down hill since 500 ,the " dead " of Juvia is hte beginning . I got feeling Hiro just try to a hot point in story line , but accidently he made a bad ones , so he trying to fix that by making a char like Gray had showdown with Natsu in the most kawai way . And then he relize " oh shit i made mistake again , may be i would add some drama to this point + keep teasing us while he think the way to fix this situation , like we got so hype END and Gray get power up too , Gray he can not be kill at this point , not with a stupid way like this , and END can not die at this pointr too , if so who the fuck gona deal with Zeref or Acnologia :)) ,
so after awhile he dive up a Eza magicaly somewhere jump in middle a fight ---> good Hiro sama :)) . I just hope he wont make Gray like this , bring back the Gray that we used to know before . Let just say Gray is powerfull enought to kill Natsu , after that good luck have fun with Zeref + Aco :)) and dont think u got enough men power to do a job , then again good job Hiro :))
The Gray i knew would let Natsu go to zeref , he kill zeref he die anyway ,plus good one Hiro . ( sory for my English not good )
