'If only you knew what he asked in exchange.' Yvonne sneered at the thought of what she had to do once she returned to Amarthea.
When she had sent back word to SO that she was willing to meet him only if he agreed to her condition, he had been hesitant at first.
After numerous letters going back and forth through the means of Tutu, they had finally come to a conclusion about the terms of this favor that he was doing for her.
According to what they had decided, Yvonne could use Tutu to send her letters to anyone she wanted but in exchange, she would have to come to the place where SO called her.
It did not matter where he called her, she had to meet him there and this needed to happen once she returned to Amarthea.
As Yvonne was in a bind to get her uncle to help them out with the task at hand, she had accepted his condition and promised to meet him once this trip had come to an end.
