L didn't know what he had been suspecting when he first entertained the idea that there might actually be such a thing as a shinigami. Maybe he was suspecting a more humaniod creature, or maybe he was expecting one with a less detailed personality. Either way, he still knew that this creature in front of him is not what he was expecting.
Everyone had long since gone to sleep; Light was passed out on the couch, with Misa right at his feet. The shinigami was watching them intently, as if at any moment one of them might spring up and incite a fight. L knew there was more to their relationship than there appeared, Light, Misa, and the shinigami, but he also knew that extracting that information would not be so easy.
A long time ago, he had asked Light whether he thought it was possible for a human to know the future. Unlike many others, he didn't ask this to test Light's reaction, but out of actual curiosity. He had a feeling that he was on the right track, he could feel it deep in his gut; Light Yagami was Kira. And now he knew for sure that within the next few days, he would find out whether this really was true.
L reached for a random piece of food. His fingers grazed a smooth surface, and when he picked it up, was surprised to see an apple. He definitely hadn't seen it there earlier. His eyes flashed to the shinigami, who was still trained on the couple on the couch. He turned the apple over in his hands. Quietly, he stood and dragged his way over to the mysterious creature.
Rem turned her eyes to meet him. She obviously had as much contempt for him as he did for her. He stopped in front of her and held up the apple. She gaze him an odd look, or as odd as shinigami can give. He continued holding up the apple, as if she might snatch it at any moment.
"Death gods love apples, correct?" L asked. Rem didn't say anything.
"Perhaps not." L let the apple slip from his hands and fall to the floor. It gave a loud bounce before settling by Rem's feet. L shuffled back to his seat without another word.
Now Rem's eyes were trained intently on L. She knew he was trying to play some kind of mind game, but as with most, she couldn't figure it out. Misa turned over and Rem's eyes snapped back to the couch. L was back to being occupied with his food, but it looked like their brief interaction wasn't over.
"Why aren't you asleep?" Rem asked.
L took a bite of ice cream. "Insomnia, I suppose." Leave it to L to state the obvious.
Rem didn't say anything. L was anxious; he wanted to find out as much as he could about the Death Note, but had no way of testing it without the others here. L picked up the notebook and opened it to a random page. He scribbled something down, drawing Rem's attention.
"What are you doing?" She shuffled over. L didn't bother to hide the notebook, leaving out for her to see.
"I'm quelling my curiosity." L shut the notebook as Rem peaked over his shoulder. Her eyes went wide on noticing what he had been writing in.
"What do think you're doing?" She hissed. L slid the notebook back into it's package.
"Writing in the Death Note." L said.
Rem's head turned back to the couple on the couch. L could almost hear her count the seconds, waiting for one of them to suddenly stop breathing. Her eyes turned back to L, who looked completely indifferent. She looked tempted to open the notebook and see what he had written, but ultimately thought better of it.
Before walking back over to her previous position, Rem had one last thing to say to L.
"If anything happens to Misa, it will be your head."
L bit back a smile. Of course, he knew better than to write anyone's name in the Death Note. In fact, he did something even better. But that wasn't his goal. He knew something now that he didn't know before. He wasn't going to get any information out of this shinigami. Rem was attached to Misa, and Misa was attached to Light, that meant that he probably had both of them wrapped around his finger. Say what you want, but he was good.
L took another look at the shinigami. He knew he was close; he could feel it. It wouldn't be long before they got the evidence they needed to catch Kira. But, somewhere deep down, L also knew that this might not end well. But that could wait until tomorrow.
