Well, don't forget, in order for a speech to be compelling, she'll have to know what is compelling to each character. Just the "greater good" argument isn't going to have any effect on Kit.<br/><br/>"It's for the greater good! Eventually, they'll get you, too!"<br/>"I've felt that way about humans for almost four hundred years, none of you wanted to help avoid a genocide then."<br/>"But, it's only a matter of time before they kill you!"<br/>"I've hidden from the entire world for four hundred years, I can hide from one douchebag that isn't even after me, highness, for a few decades before he croaks."<br/><br/>Kit isn't the most agreeable person ever.
