User blog comment:FairyRaven/Fairy Tail Chapter 397: Steel, Review and Commentary/@comment-7418318-20140825132453

Nitpicking time! The Human body is made to a big part of carbon. So why does Gajeel need to absorb carbon from the water to turn his iron into steel? Also wasn't his nickname Black Steel Gajeel? And if Torafusa is able to harden his body as much as he wants, why didn't he just harden himself even further after noticing that his current hardness is no longer sufficient?

Putting that aside it was a nice chapter with two great quotes. I'm looking forward to Natsu's attempt at singing... and I wouldn't be surprised to see Lucy dancing to his song in her bunny costume, but this time without Levy.

I am wondering who's going to keep on fighting now though. Gajeel, Natsu, Lucy, Levy and Juvia are all poisoned, so they shouldn't be able to. Mirajane seemed exhausted as well. Makarov isn't there any longer and the Raijinshu and Laxus are sill out cold as far as we know.

So unless Gildarts makes a surprise return or CS+OS turns up, that leaves only Wendy, Erza and Gray, but with Erza being on the way to Command and Controll, it'll be Wendy or Gray I think.
