How we cite our quotes: (Part.Chapter.Paragraph)
Quote #1
I miss my own [name] and I mourn for everyone else's, because I'd like to love them, but I don't know who they are. (1.1.7)
R finds it impossible to love someone if he doesn't know their name. This is one of the reasons he falls for Julie so hard: she's the first person he's met in a long, long time who has a name.
Quote #2
I think I remember what love was like before. There were complex emotional and biological factors. [...] The new love is simpler. Easier. But small. (1.1.40)
Boy, yeah, love is complicated. R finds that without all the hormones and pheromones and pesky social things like talking or finding something in common, love is heck of a lot easier as a zombie. However, making it easy also kind of takes the fun out of it.
Quote #3
I want our cells to braid together like living thread. (1.2.40)
This is Perry's thought when he and Julie hook up for the first time. He has this desire to become one with her—which is another subtle foreshadowing, as at the end of the book Perry inside of R does end up combining cells with Julie (and vice-versa) to create something new.
