It was a bit funny to see Percy so disgruntled, but Ginny also understood how he felt. Being pulled from your own time and into another wasn't exactly an easy thing to deal with. And that was without adding different ages of the people you were close to into the mix.
"Yes," Ginny sighed, realizing at Percy's question that she actually found that bit quite frustrating. Hermione was the closest to her in age, but Ginny was still over a year ahead. "Harry's only 19, when he should be 21 for me. Hermione's also 19, but she was about to turn 22 for me. And Ron...." she reached up to run a hand over her face. "Ron's 19, but he's been here for a while. He was barely 18 when he got here."
Ginny opened her mouth to explain that Percy would have to be careful around Ron, but she hesitated just long enough to decide against it. They'd get to that bit, but she didn't want to blurt it out just yet and risk upsetting Percy more.
Nodding at his question about MACUSA, she shrugged about the demon. "No, demons are something meant for religious people, I think. But...." she paused, her eyebrows drawing together in thought. It wasn't the first time she'd thought about this particular avenue since arriving, but it was the first time she said it out loud. "I think Voldemort would qualify as a demon. At least in the sense of something we can understand. So it never crossed my mind to question anyone when they said there was a demon. I've already seen one."
She'd done more than see one, but Ginny wasn't going to go there.
