Nathaniel isn't intimidated by Teren. Maybe he's one of the few. He is least of all intimidated by a liar who is hiding from the consequences of her actions. And he's not messing around. The Wardens gave him honor, gave them all honor, and that is under enough assault without it coming from their own side.

He approaches from the front. She can see him long before he is close enough to speak. And if she runs from him, he and others will be witness to her cowardice in action.

And he doesn't look happy.
