So I've read up to chapter 30 but I have one slight question about Grige.

Spoiler for spoilers:

He was shown to be actually really scared of a real battle, to the point where he couldn't even move. Then without explanation he came to the rescue, all confident and stuff, and beat everyone to pulp. There was no explanation on how he transformed from cowardly back to the way he was. Or did I miss a chapter? Or was he just acting it up so he could separate himself from the team?
