If it weren't for Gray's self-control, several things might have flown around the room.
But he was able to control himself and study what Matt was saying.
'Alice fought with her... I see, that's why she told me she had fought with a scary woman. How the hell did she fight with that strange woman? Even that Edevane woman was recently injured by her and had to spend some time healing.' Gray couldn't understand this, but his expressions, despite trying to hide them, were very obvious to Matt.
Since learning of Gray's plan, he raised all his defenses to the highest and used all his ability to talk to and look at this man. Any information is precious when you're facing possible death, after all. And while he wasn't entirely worried, it was still wise to do things carefully.
After all, in a head-on battle, at this point, Matt would lose miserably to Gray.
