Quote 13
Everything—the walls, the floor—has been done in gleaming white tiles, which the centre keeps so clean when you first go in it's almost like entering a hall of mirrors. Of course, you don't exactly see yourself reflected back loads of times, but you almost think you do. (2.26)
The recovery center at Dover sounds just like a fun house at a fair. Having your image reflected all over the walls might be a little off-putting, but it does point out how important mirrors are. Inside the tiled walls at the recovery center, Kathy can't really escape seeing herself everywhere, which is a constant reminder of her fate.
Quote 14
So you're waiting, even if you don't quite know it, waiting for the moment when you realize that you really are different to them; that there are people out there, like Madame, who don't hate you or wish you any harm, but who nevertheless shudder at the very thought of you—of how you were brought into this world and why—and who dread the idea of your hand brushing against theirs. The first time you glimpse yourself through the eyes of a person like that, it's a cold moment. It's like walking past a mirror you've walked past every day of your life, and suddenly it shows you something else, something troubling and strange. (3.73)
Kathy doesn't like seeing herself through Madame's eyes. It's no fun to realize that other people are disgusted by you. Plus, realizing what Madame thinks of her seems to change the way Kathy thinks about herself.
Quote 15
Nevertheless, we all of us, to varying degrees, believed that when you saw the person you were copied from, you'd get some insight into who you were deep down, and maybe too, you'd see something of what your life held in store. (12.12)
According to this theory, the apple doesn't fall far from the tree. Or the clone doesn't fall far from her "possible." So finding your model would be like getting a cheat sheet for your own identity. But what part of your identity will you get to discover when you find this model? And what do you think Kathy means by the phrase "deep down"? Maybe she means she'll learn more about her personality. Or her soul. Or her DNA?
