He opened the door, cautious not to wake her up. He couldn't help but smile to himself when he saw her curled up in a ball against the wall, trying to keep warm. She looked so innocent. So cute. So weak. The only time he ever liked humans were when they were too young to talk, sleeping, or dead.
He calmly walked over to her and picked up the key that had half-way fallen out of her pocket already. You won't be needing this anymore, he thought as he replaced the nr. 5 key with the nr. 1 key.
"Remember to see me when you find the key," he whispered, knowing she couldn't hear him.
Then he left the room, closing the door behind him quietly.
