Peter doesn't get angry often, but when he does, he's like ice and silent fury; but Edmund is just the opposite - his anger is a quick, violent burn that sometimes makes him tremble with the passion. Lucas laughs until he has tears in his eyes to cover a secret hurt, while Sam goes out and punches things until his hands are raw and he falls down sobbing to the ground. Boys don't cry, they were told in their old life, but they all know better and there's no one who would judge them for it.
