Not at all. Even if Gray were to find out about E.N.D., what would the awakening of E.N.D. accomplish? Do you expect him to take out Invel? Then what? It will be pointless. It'll be okay if Gray were to know the truth and question Natsu and stuff like that but E.N.D. awakening right now would be a waste.
