Say Free, if Ssarak were to become friendly, commenting that he does not wish to have hostility among friends and noting that they have physical evidence on them that they need to turn over to Lucilia, would Grey still stand in their way?

He is convinced they are overreacting, and he feels they'll do something rash. That, and he can't help to be so overprotective, since he's bound to her he is unable to willingly leave her undefended if he's in the area and there's a perceived 'threat'. That, and he distrusts Psychomancers on principle.
