What did Lena see when she first saw Hannah?

Lena's abductor helped her sit up, and she saw a girl child. The girl was standing stiff in pajamas that were much too large for her. She had a serious, pale face. She seemed to be holding a little animal. She appeared to be slightly younger than the boy. She was shorter and a little more delicate. She had the same pointy chin and thin hair. Her hair was blonde.
