Sebastian looked over at Melissa with a surprised expression. She really was an expert at this kind of thing. He never would have known to say that at all. He would have a lot of work to do if he was going to be a mentor like she was. 

But, looking back to Grace, he could definitely see that that was the reason for her lack of control. But the next step here was to find a way to get her to let go of her fear of hurting other people. The ability to control her powers was there, what she needed was someone that she could feel comfortable with. 

"I'm... sorry to hear that about your sister, Grace. It must be difficult to have to live with yourself after that. But from what you've told me, it wasn't your fault." Sebastian moved closer, putting a hand on her arm gently, immediately feeling how cold it was. "You have to trust yourself. Look, I'm right here and I'm not dead! Kinda cold, though. Remind me to bring some gloves and a jacket when we talk like this." He smiled cheerfully to try and bring her spirits up. It would be a long road until Grace would learn how to control her powers, but he wouldn't give up.
