text: You stick your foot through the doorway, and it vanishes from sight. You feel it passing through an invisible wall, like sticking your foot through a flowing sheet of water. However, when you pull your foot back to this side of the doorway, you can see it again, and it feels fine. You take a deep breath, and plunge through the doorway...
  
  You stumble to a halt as you pass through. As your face passes the invisible wall in the doorway, the endless white expanse of nothingness vanishes from sight, to be replaced with Karl's sleeping quarters! You look around the room. There's a bunk against one wall, a closet with Karl's clothing against another wall, and a small desk unit with some of his various odds and ends.
  
  Turning to look out the door, you can see the passageway fine. Opposite Karl's open doorway, you can see the door hatch to your own sleeping quarters, and it is closed shut.
  > You wait around, and see if your granddaughter comes past this room.
  Perhaps, you think, you might run into your granddaughter again? You sit on the bed, but then you realise that in this room, there is no blaring sound of the intruder alarm. Karl's room must not be in her era of time... Besides which, looking about the room, it looks like it is indeed Karl's room, and not being used by someone else.
