How we cite our quotes: (Chapter. Paragraph)
Quote #4
This was therapeutic physical contact, Chloe said. We should all choose a partner. (2.54)
It's not immediately apparent this early in the book, but our narrator doesn't have any friends or romantic relationships. He never mentions any past girlfriends. Maybe Chloe's suggestion to choose a partner is a subtle hint that a romantic relationship might do him some good.
Quote #5
I tell Tyler, Marla Singer doesn't need a lover, she needs a care worker. Tyler says, "Don't call this love." (7.70)
Here's one place where our narrator and the Tyler side of his personality agree: they are not—repeat: not—in love with Marla Singer. Hmmm, we think the multiple personalities doth protest too much.
Quote #6
Even if someone loves you enough to save your life, they still castrate you. (8.54)
Marla is talking about the love between a dog and his owner. But we have to wonder if this is part of the whole love-denial thing our narrator and Tyler have going on. Will being in love with a woman make them less of a man?
