Meg watched the tension as it rippled through the girl, but noticed that she didn't immediately reach for a weapon, meaning she probably didn't have anything too powerful at her disposal. That was a relief all by itself. Unless she was packing an Angel blade or the knife, she couldn't actually kill her, but she could probably still do some damage. The knifes that had spilled out of her bags looked vicious enough, but Meg wasn't exactly afraid of them, as long as she could keep some distance between herself and the girl.
She was being ridiculous, of course. Her first reaction should have been to flatten the girl and run for it. She could crush her to the ground without even blinking and leave her there. It's what everyone expected her to do, she was sure. Hadn't Sam implied as much? She was a demon, and couldn't be trusted, no matter how many times she stuck her neck out for them. Still, she didn't do it. She kept her hands at her sides, and took a step backwards, trying to nonchalantly put some distance between them.
The girl's question caught her off guard though. She'd been right. The boys clearly hadn't talked to her yet.
"A few months," she answered in as conversational a tone as she could manage. "Been soaking up the sun," she couldn't resist the urge to twist the knife a tiny bit, "swimming with Sam, enjoying life and all it's many possibilities." She took another tiny step backwards, preparing for the moment when she could break and run for it. Maybe going back to her house, with it's wards, was the better idea after all.
