Identity Quotes in Daughter of Smoke & Bone

How we cite our quotes: (Chapter.Paragraph)

Quote #7

For the first time since [Akiva had] lost [Madrigal], his memory failed to conjure Madrigals' face. Another face intruded: Karou's. (25.31)

While this sentence can be interpreted as Akiva's newfound love/lust for Karou replacing his memory for Madrigal, it's also some subtle foreshadowing about Karou's true identity.

Quote #8

She rushed into herself and was filled. [...] She was whole. (44.3, 44.6)

Snapping the wishbone marks the moment when Karou knows exactly who she is. The pieces of the identity puzzle finally snap together. Man, we wish it was this easy in real life.

Quote #9

[Akiva] wore a horse mask of molded leather that covered his true head completely. (51.13)

The chimaera play with identity at the masquerade ball. Human-types dress as animals and vice-versa. Here, we see Akiva don a horse mask. What do you think he's trying to say about himself by assuming this as his animal identity?
