Somehow, Jaina knew it wouldn't be that easy. When it came to her father, it never was. However she was looking forward to the challenge. It wasn't every day she was able to prove him wrong, after all.
"No," she replied, "that is not all. I can prove I'm your daughter. Just name it, and I can do it." She could always offer on her own terms, of course, but she knew from experience that letting him call the shots tended to get the job done quicker.
Provided, of course, he didn't decide to try and just dispose of her right then and there. He'd fail, of course, but Jaina would rather it not get to that point.
