"I wish you the best of luck in finding a way out," Lily said sincerely. If she thought she'd be any help all, she would have offered. As it was, she imagined whatever had done this was well above her range of problem solving skills.
"We were trying. But he hides, and he sends his minions out, and he is very powerful, and skilled, and always surrounded by his Death Eaters." She was somewhat amused by the snake analogy, if only because it was so fitting -- him having been Slytherin and all.
Lily shook her head at the request for a demonstration. "There's a reason they're called that," she insisted quietly. "They're dark magic, and I wouldn't cast one." Not willingly, anyway. Under extreme duress or self-defense if everything else was failing, she may resort to it, but she didn't think so. "They're spells that kill, that cause pain, and that let the caster take control of the mind of the one they've cast upon. Good witches don't use them."
A little smile crept onto her lips at the shift in topic. "You don't already find things about this place seriously unusual?" She asked, an almost teasing lilt to her voice. "This situation ... I've never been in anything like it."
She could sadly relate to Susan's little rant on stupid superiors, and yelling at them. She herself had had heated discussions with some of her professors. Generally over a grade, but occasionally over other instances. There had been some memorable discussions with the Headmaster when she was head girl, and Lily smiled -- sadly, and a little fondly -- at those memories. "I can relate," she assured Susan softly. "Sounds a bit like the way I'd handle things."
