When does Cassia wonder if her Match should really be Ky?

Realizing that she lost a lot of time reading, Cassia runs the rest of the way. Ky is the only person there ahead of her.

As others come to join them, Cassia realizes she needs to destroy the paper her grandfather gave her. She realizes that she heard someone near her as she was reading it. Ky tells her that he saw her. He touches her arm, and she wants to touch him back. As they go down the hill, she thinks about the words she read and wonders if her Match really should be Ky.
