Rachel didn't like this guy, she REALLY didn't like this guy. He's too smart for his own good, or at least he thinks he is. Makes sense as he fancies himself as a researcher or something. The tactician crossed her arms at the Dark Mage's would-be threat. She was almost positive between her and Talbot that anything this man could hurl they could return twofold, in fact she almost wanted him to try it, almost. 

The tactician's eyes narrowed by the end of the man's speech, her mind produced a counter rather quickly, one that would hopefully expose his true intent of whether he meant to harm them or not. "Well, since you have so helpfully outlined all relevant information, what do you propose us poor, defeated Shepherds do? Surely you don't expect us to trust strangers who know who we are, even if they claim to mean us no harm. So tell me, from our perspective why would we even consider taking you with us? Why couldn't we just kill you for the supplies and be done with it?" Hopefully his response might shed some light on what it was he truly wanted.
