"How come you weren't scared?" Xavier asked Emma, his face furrowed. "I was afraid more than you," she said, sitting with a straight expression. "But why can't I see on your face?" he asked, his brow furrowed once more in perplexity. "Because I'm terrified inside my heart and don't overreact like you," she said, as if playing with danger was second nature to her.
