When Mitch jumped, it wasn't due to death striking him down, but more of concern over Morana shaking and apologizing over what seemed like a no-big-deal situation to him. It was obviously a big deal for her, however. One part of him wanted to touch her shoulders to try to calm her down, but another part worried that it would freak Morana out even more if he tried to hug her. He really didn't know how to comfort people, much less frightened girls.
So instead, Mitch held out his hands, lowered and palms-up, showing her that he was all right. "It's okay, Morana, it's okay. I didn't hurt ya, did I?"
