How we cite our quotes: (Part.Chapter.Paragraph)
Quote #1
It made me wonder, thought, what would have happened if Kate had been healthy. […] Certainly, I would not be part of this family. (1.1.4)
Anna's whole existence happened because Kate was ill. It's a weird situation to be in, kind of having to be grateful that your older sister has cancer.
Quote #2
[The nurse] removes the needle, and sticks Kate again, who howls even louder. (1.3.34)
"Howls even louder" are just three words that cannot describe the pain Kate must be going through… or the pain Sara feels at having to watch her daughter suffer.
Quote #3
My sister's in pain, and I'm relieved. What does that say about me? (2.1.21)
Anna is too young to know the term schadenfreude, but that's not what's happening here—Anna is just glad that her mother is distracted, and that this takes her attention away from Anna after Anna files the lawsuit. (Which is weird, because isn't attention what Anna really wants?)
