There were two sides of Julian, she thought, and she remembered a line from something she'd read --Emily Brontë, maybe. Different as a moonbeam and lightning. She wanted to reach the moonbeam part, but she didn't know how. Very softly she said again, "I don't believe you. You're not like the other Shadow Men. You could change --if you wanted to." "No," he said bleakly. "Julian... " It was the bleakness that got her. She could see herself reflected in his eyes. Without thinkng, she moved even closer. And closer. Her upper lip touched his lower lip. "You can change," she whispered.
Julian is portrayed as having two contrasting sides, like the difference between a moonbeam and lightning, a metaphor she recalls from reading. She struggles to understand or reach his better, gentler side, feeling that he is capable of change. Despite her desire for him to be different, he remains bleak and unchangeable in her eyes, which deeply affects her.
Her feelings intensify as she sees her own reflection in his eyes, and impulsively, she moves closer, even touching his lips, whispering that he can change. This moment highlights her hope and belief that he is capable of transformation, despite his bleakness.
