You walk around a large hole in the floor of the large room. The room is split down the middle by the entrance to the living room and the backdoor exit.
To your left is an area that might have been a kitchen at one point, but now the appliances are gone and the cabinets are rotting away. The only other feature is a half-rotten staircase leading down.
To your right is a dining table with both it and its four chairs in surprisingly fine condition. Next to the table is another staircase, but this one is not rotten at all and it leads up.
You wonder at the strange contrast between the table and the kitchen until you realize someone is missing: John. He could be up or down the stairs, but it occurs to you that he could have chickened out of the dare.
