He was quite accustomed to those around him being attacked. Even before he'd gone off to war, those around him were constantly targets. His poor mother, before Astrielle removed her threads from her tapestry, was always being attacked by the Queen in some way or another. The Queen consistently made sure to ensure both Caspian and his mother remembered their places always. And then later, when the Queen had signed off on him going to war at fifteen, watching those he'd once shared dinner with die became commonplace. He learned very quickly how to separate his heart from the matter altogether. The same way doctors dealing with the poor who can't afford Healers deal with all the death they, too, must see. He went numb for his own peace of mind.
