I Never Promised You a Rose Garden Chapter 16
Deborah tells Furii another secret. Deborah admits that she was a captured Japanese soldier during World War II. That was an explanation for her otherness at the time because Deborah was the enemy, and although she was Japanese, no one ever recognized her.
That night Deborah feels a breakdown coming on and asks for help. When she wakes up in the pack, Sylvia is in the room with her. They stay in the pack for so long that Deborah is in pain, and Sylvia talks to her until the attendants come to unwrap them.
Deborah realizes that the last of the deceptions hasn't happened yet, and so she knows that Furii will be the deceiver because Deborah has revealed so many of her secrets to Furii. In her next session, she tells Furii that she knows it's coming. Furii promises to prove her trustworthiness, but the only proof she can offer is time.
