The very second N had left White, he'd regretted it. After the final confrontation with his father he'd left to 'find himself' when in reality he'd known what he'd wanted all along: love, acceptance, adoration, one person to be his. When White had waved to him, he'd felt hesitance, the desire to return and take her with him. He knew he wanted her.
"I WILL have her." He chanted "I will have her, when I'm stronger. I will have her, when I'm stronger..."
Desire had created a sore on the heart of the one pure hearted prince. It began to fester.
