None of the elders spoke up, all of them were lost in their own thoughts, focused on Azrail, marking him. What he showed just now suggests that there is more to see than what is being told.
A lot of secrets are hidden within Austin, which also shows the fact that he is not one to be easily messed with. Azrail could feel it; the tension in the room was sky-high. The eyes of the elders, in a hidden manner, were fully focused on Azrail. He could feel them weighing him, understanding him on a deeper level.
'They don't want to make a small move yet; they want to know more.'
