This was exactly what she had wanted. If he let her go now, the plan will have worked after all. If she said yes now, that she wanted to leave, he would send her away and she would go free. Then when word reached him that she had been the lady all along, the ransom would be cut almost in half for the fake Terra. It was exactly what she had wanted from the start. But, she didn't want it anymore. The money for her ransom could help the Fox and his people so much.
Deep in her heart, she knew that was just and excuses to stay longer, but it was a good thing to tell herself rather then admit the truth to herself. The truth about her own feelings.
She shook her head, "I don't want to leave Fox. I... I don't know how to say it but... you know that I can't stay here. I am not one of your people. What good could I give this place? The only good is the little bit of money you will receive along with the bulk for Lady Terra. You say you don't need my ransom, but your people do. They need every penny they can get to make up for every penny that has been taken from them. You know that's the truth. So... while I would love to stay here Fox, you know that realistically, I am better off being ransomed with Terra."
