Lemons.
The sharp smell of citrus wafted down the hall, crept under the small space between the door and the carpet and permeated his nostrils. Vergil frowned slightly, and put aside the book he'd been reading. When he opened the door to investigate, the scent grew even stronger. At first, he'd assumed that the girl was doing her cleaning routine and had decided to use some lemon scented furniture polish.
But, no. After a moment, he decided that tt was much too potent to be anything but the real deal. Curiosity piqued, he followed the smell down the hall and into the dining area. The human was sitting at the table, reading something on her laptop screen. The scent in here was overpowering and clearly the source.
"What are you doing?"
She jumped and snapped a look over her shoulder, startled expression quickly melting into a pleased smile. For a moment he was rather surprised at how happy she seemed to see him.
"Hi Vergil." She chirped. "I'm just up to no good on the internets."
"What's that odor?"
A tilt of the head, then she held up a small plate laden with bright yellow crescents. "Lemons."
"What are you doing with a plateful of raw lemon slices?" Vergil wondered if she was making lemonade, but he could see no other ingredients near.
Without answering, she held a piece up and took a bite out of it. After a moment, she grinned at him with the yellow rind in front of her teeth. At his surprised expression, she giggled, took the rind out and swallowed the sour fruit.
"You're eating lemons?" He asking, flattening his mouth in exasperation.
"Yeah. I like 'em." She ate another slice, and seemed to sincerely relish the taste.
He stared at her for a long moment and then shook his head, sighing. "You're very, very odd," he said, turning and heading back towards his room.
"The half-Devil calls me odd," She muttered to herself. "The irony is almost painful."
"Shut-up and eat your lemons," He called back, just before closing the door.
