Panel 1: First person view from the librarian, the shaking lines blacking out at the edge of their vision. The edge of a hand can be seen close to their face with the other hand clenched on the table in front of them.
Panel 2: The librarian looking up slightly and seeing the box with the key in it in front of them on the desk.
Panel 3: The box standing alone in a white panel that cuts through the noise.
