So it looks like it was Gray that killed Frosch after all. People have been hyping it up for a short while now.

I was a bit worried about Sting also, was trying to figure out if he was Droy 2.0 or was doing something similar to Reedus.

I hope Natsu run into Gray next episode and to see what develops from it.

I am a bit worried though about the lack of information there has been on Avatar for them to make it look like a simple job seeing that only Rogue and Minerva were going on that job.
