The Truth Comes Out

"You were brought into this world for a purpose, and your futures, all of them, have been decided." pg. 81

It's really no surprise that Miss Lucy is the one to break the news to the children that they are raised for organ donations, because it's just the way her character is. She often worries about the children because they do not seem to grasp that their lives are not normal, so she wants to warn the naive students of what is to come.

Also in this chapter, Ishiguro discusses the issues of Tommy's elbow and organ donations:
"Don't you know? If it's right on the elbow like that, it can unzip."
"The idea was that when the time came, you'd be able just to unzip a bit of yourself, a kidney or something would slide out, and you'd hand it over."

The unzipping gives an image of something being opened rather simply, without much effort. Kinda odd, but the zipping is like a euphemism. Instead of saying, cutting us open, they say unzipping. This word "unzipping" shows us the student's fear at this point. They are afraid to discuss the actual donations outright with everyone, so when they do, they joke about it to cover up their true feelings about what it is to come. It's much easier to talk about giving organs when it sounds as quick and easy as zipping a zipper.
