The school was very weird. It's hard to imagine there would be any government left to pay schools for each student anymore. It was more like the dorm supervisor lady was cracked in the head beyond repair and couldn't let go of the school. But then again, considering the students were all weirdos, it's probable that had something to do with the school existence. The abducting men might have been some hirelings and not present during nights at all. There's not much the lady could have done at that point, considering she had a six-shooter while the dude had an automatic pistol, so assuming he had a full complement of bullets, she would have lost inevitably.

Scar's situation interests me as well. I thought maybe the genuine gravekeepers have short lives and she's nearing the end, but that would fit poorly together with accepting the baby back in the city of the dead.
