"Please," she begged, pulling on the bars. "Let me leave."
Draco stepped forward from the shadows. He shook his head. "You can't leave, Luna, I won't ever let you."
"You can't keep me here like this!" Luna screamed, hoping someone would hear her voice. She knew they wouldn't though. She was trapped here, with him.
The war was raging on around them and her friends and family needed her. But he wouldn't let you leave.
Draco moved forward, gently caressing her face. "Luna, I'm keeping you safe here, and one day you'll thank me for it."
She stepped back. "Don't touch me."
"Don't try to escape Luna, I won't let you leave," Draco said, finality in his voice.
Luna sent him a mutinous glare.
"You can fight me as long as you want, but you're not leaving. If I keep you here, you're safe. I won't let you get away from me."
"I will one day!" Luna protested, shaking the bars.
Draco shrugged. "I doubt that, but even then, I'll find you again." He leaned in close. "We're meant to be together Luna. I know you've seen it, the way our auras blend together. Don't try to fight it."
"Go away," she whispered, afraid. She was afraid because she was trapped here. She was afraid because she didn't know what was happening to her father. And she was afraid because she knew Draco was right. Their auras were perfect matches. They were soul mates. But she refused to believe it.
"You'll come around Luna," Draco said, sounding quite sure of himself. "You see this as me preventing you from escaping, but I see it as me protecting you."
Luna was quiet. She didn't want to talk to him anymore.
"I'll be back later today Luna," he whispered, reaching into the bar.
Luna recoiled, scooting away from him.
Draco shrugged. She'd come around. And then they'd be together.
