The Woman in Cabin 10

A knock comes at the door, and the woman in Cabin 10 returns. Before she opens the door, she demands that Lo behave, and Lo acquiesces. The woman gives her a pill, along with a tray of food. She has only brought one pill.

Lo asks what the woman will do with her, and the woman suddenly takes on a dark expression. She says that it isn't up to her. The woman looks in the mirror and realizes that she has blood on her face from their confrontation. She implies that if the man who is in charge realizes what has happened, something bad will happen to Lo, and washes off the blood in the small cell sink. When the woman looks back up, her identity is revealed. As she washes her face, she has also washed off a perfectly painted-on eyebrow, revealing a bald, gaunt skull underneath. The woman is Anne Bullmer, wife of Lord Bullmer. 

After Anne realizes that Lo has recognized her, she shrugs and leaves the room quickly, slamming the door behind her. Lo is in shock, and realizes that it was not Ben but Lord Bullmer who was in charge of both Lo’s kidnapping and the threatening messages.
