Iris listened to his words thoughtfully. A sorry would not be appropriate so instead she sighed. "There are alot of people in your same position. The difference is that you have chosen to do something about it. My only suggestion to you is to make sure your mind is under your control. When your out in battle, you want to reign in the bad memories and grab power from them, like you said, it is your drive." She looked to her mentor, knowing his story had likely hit home for her, but her face had shown nothing. "Remember this..." she said looking back at him. "The reason you want to fight needs not to be because you want revenge. It needs to be because you want others to never feel that pain. Use that as your drive. As a Ranger, you are no longer fighting for just yourself." 

With that said, Iris retrieved two katana and gave him one. "Show me how strong your drive is." she said stepping away and preparing herself. She spun around and placed her wepon in her left hand, bringing it across her chest like she usually did, keeping her feet apart. This was the same one she always did. You could tell alot about a person by their stance, she would be looking for something specific in his.
