Chapter 6:
It's her day off again, or maybe just not her shift. He sees her poking through the shelves before he goes off to find a book to read during his regular torture session of being surrounded by insects. He forgets about her temporarily until he sees her reading the same book he was looking for. It's the last copy until the next shipment. She sees him and asks if he would like to read it. He doesn't say anything but she quickly puts the book back on the shelf and slips off.
He takes the book and silently thanks her.
