GET OUT

[Lucy]

ponder what else you have that might be able to wedge the shelves in place while being strong enough to hold your weight.

The door handle perhaps? Assuming whoever built this place is sensible enough to use the far superior lever-style handle rather than the antiquated knob-shaped handle that no one likes.

Also assuming it's made of metal and not, like, wood or something.

You take the door handle back off the supplies door, it comes off easily like last time. It is one of the knobby types sadly, with a couple loose screws lying flaccid in it ready to be attached to some sort of hole. You'll give this a go anyway. You head back to the supplies room and carefully lay the odd hourglass like shape it takes diagonally over the edge of the floor, and stabilize it there with your foot. You push as hard as you can down on the shelves while holding it here and wedge it between the shelf and the floor. This should stop the shelves from moving now. You hope. It doesn't seem too strong. It can take your weight, for now.

What is to be done?
