Isabel's eyes actually started to show some emotion for the first time since the two met, as they flared up with a small bit of hardness and anger at his accusation. "Absolutely not." Of course she didn't expect him to understand... how could he? It wasn't like he could tell that she was different from normal people, he had yet to actually see the way she moved and fought in combat. Truth be told though, this mission actually was a little bit personal for her, in that Isabel typically didn't have any qualms about killing people during combat, it was her job... but that one person was special.
