How we cite our quotes:
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.
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.
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?
