My character has failed the interview and was attacked by the tchortist. Yet the quest still remains open and is not marked as failed:
Also, even though my character managed to persuade the old rejected to leave his cage, and all the tchortist in all accessible areas are dead (as well as the creatures in the West Wing, except for the faceless), there is not dialogue option to tell him that. Which makes little sense, as in another rescue scenario (Newton at SGS), the NPC acknowledges that the way out clear.
