The level of badassery in Gray's new powers tells me that either something really fucked up is gonna happen to him, or it's just a temporary (though not one-time) thing, or the E.N.D. situation is gonna drag to the next arc. That would be a little bit too much if he was just casually going around freezing people on a whim, and also it would take away the intellectual part of his magic and rivalry with Lyon (although I can't say I wouldn't like to see Lyon's face when his ice dragon gets eaten :P). It just doesn't seem to make sense in the long run.

Also, the way his tattoo wasn't there in the beggining and then reappeared on his will hints that Lucy's Aquarius powers might work in similiar manner. I assumed at first that it was just one-time, but it already reappeared few chapters past, and seeing how Gray's one behave it might not have just been Mashima's mistake. Which is a little bit strange too, because though not as much overpowering as Demon Slaying magic seems to be, it kinda overlaps with Juvia's territory. Does it make sense? Are they gonna perform Unison Raids left and right? Is Mashima aiming on creating a little fire brigade? -_o I wonder.

And I just loled at the Gray's first panel in this chapter - he looks like freakin' cupid xD And aims at Tempesta, is it that Boys Love? ;)
