Mary Lynn laughs, then walks away without another word. As you watch that fine ass scoot out of your life, and with it your hope of having a normal-sized person to carry you around this now giant world, you start to wonder how you're going to handle this. The gun is just gone, and you honestly don't have the slightest idea what to do. Maybe somehow you'll be able to find security footage of someone taking the gun, and identify them somehow, and get the gun back from them, but that seems awfully far off to you just sitting there on a library shelf by yourself, barely an inch tall. You doubt there's a camera pointing at your aisle in the stacks. You'll have to figure something out, somehow.
For now, you have to figure out how to get down. Sure, there are a bunch of books here, but are they really going to work as footholds? Even the next shelf down has to be at least a fifty-foot drop. Are you really going to risk it?
