There was an incident with Road, a while ago. [His voice has that soft quality to it again.] Someone was friends with her, and then was told by one of the Exorcists to stay away from her. In retaliation, she trapped him in her dream and forced him to watch the deaths of his dearest loved ones. Then she forced him and the Exorcist to nearly kill each other.
We haven't warned people since then, not on a wide scale. They've only hurt Exorcists since that incident. That may not justify things in your mind, but... we're doing the best we can.
