A lot of the rules that pertain to the actual killings were going to show up once the first death happened. That's why there's also no "3 people discover a body alert" regulation, or any mention of the court of carnage. But those rules will most likely get revealed if Cyrus makes an address in front of everyone.

I wonder what would happen if somebody broke into a locked room during the night of carnage? Does the room stay permanently open from then on? Or does it get re-locked once the hour passes?
