Katie wanders tentatively closer to the cave, a look of rapt interest evident on her face, unconsciously singing the words to a half-forgotten song she heard as a child. "Into the dark, and what it brings. Secrete away your precious things. So many mysteries to explore..." As she gets closer to the entrance, she removes her pack and begins rummaging in it, never taking her eyes off the cave.
After a moment, she pulls out what looks like a large two-pronged fork. She continues humming the tune wordlessly as her fingers unscrew the spike at the bottom of Nutbuster, stow it in a belt pouch, and then screw the fork in in its place.
"We will need a torch," she says, almost to herself.
