User blog comment:Miskos3/Fairy Tail 522 & 523: Gray's Trump Card & Is Destiny Burning, Review/@comment-5693502-20170219002522

Apart from the revelation that Zeref's true goal is something still unknown, that whole Lost Iced Shell chapter was made redundant by blah blah, burn fate this, nakama stay alive that...

Don't like the way how Mr. CantBeKilledByAnything Zeref talks like it's so easy to kill him... if it was so easy, he'd be dead already right ? Still waiting for Zeref to show why his 400 years of life, experience and magic knowledge should really be putting him on a level matched only by Acnologia...

Two good things from these chapters:
 * Acnologia
 * Zeref looking like he'll do something offensively/August apparently didn't get Fairy Tail'd like all the other Spriggans
