The Secret Must Be Heard

K-15 wakes up alone in a glass tube, wearing clothes she's never seen before. When people gather around her and observe her actions as they poke and prod her, she doesn't know what to think. She doesn't remember anything accept her name. Something whispers to her at night, and a male scientist talks to her during the day. When she starts asking questions, she gets to know that she isn't on her home planet anymore, and she arrived there three weeks ago. Why wasn't she awake for the full three weeks, and why is this scientist being so nice, when the rest of them treat her like an animal?
