Ellanor kept herself composed as Marken explained the stipulations of their wedding, making it clear that they would be joined in name only, and nothing more. In all honesty, this could be fortuitous for her. Being wedded to Marken would give her the ability to roam the castle to retrieve the information that she was tasked to gather for her own kingdom. To break the marriage, all she had to do was not sleep with him, therefore not giving the prince any heirs. It was perfectly legal to divorce a woman who couldn't sire a son.
"Very well, you silly prince," Sylvia told Marken softly after she finished her tea, "I will marry you. And you would do well not to trust me. I think it is very clear by now that I have no intention of becoming a docile arm ornament for my enemy's son. Until this agreement no longer benefits either of us, we shall stay in this... union."
Standing, Sylvia put down her teacup and walked around to Marken, extending her hand in a very business-like manner. Right from the very beginning, she was going to be straightforward and clear with their partnership. She would not be romantic with him, and she would not indulge in sympathizing with each other. He was simply a means to an end to her.
