"Anyway, I'm not making any big claims for myself. I know carers, working now, who are just as good and don't get half the credit. If you're one of them, I can understand how you might get resentful - ...(Ch1, p.3) Assumes prior knowledge and builds interest because the reader wants to find out.
" Or maybe I am remembering it wrong..., maybe I did feel a little stab of pain" (Ch1, p.8)
"And although we hadn't had any part in this latest plan to rile Tommy, we had taken our ringside seats, and we were starting to feel guilty" (Ch1, p.10).
" So I reached forward and put a hand on his arm" (Ch1, p.11) Kathy is positioned as an empathetic character - certainly more than Ruth so at this point.
"This was all a long time ago so I might have some of it wrong; but my memory..." (Ch2, p.13) Retrospective narrative, looking back at the past. The acknowledgment that as a narrator, she is flawed - her memories may betray her/have changed over time/only show her side.
Is she a reliable or an unreliable narrator? She is willing to admit that her memories are only her side of the story.
"I don't know how it was where you were, but at Hailsham..." (Ch2, p.13) She is talking to other people just like her - clones.
"'You notice everything, don't you Kath?' (Ch2, p.23). Kath appears to be rather perceptive - a good quality - a very human quality.
"Thinking back now, I can see we were just at that age when we knew a few things about ourselves-about who we were, how we were different from our guardians, from the people outside - but we hadn't yet understood what any of it meant" (Ch3, p.36)
"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" (Ch3, p.36). 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.
