She seemed to really consider it for a moment, nodding once. "I'm for it. It might be the only way to shut him up." because knowing them, they just had to say something. It was like not saying anything was actually difficult to do. There had to be some kind of charm to fix that problem. Or just a gag, while binding his hands so he couldn't type anything.
"Possession." she repeated with a nod. "There are demons here. Apparently their true form is what looks like a cloud of black smoke. At least up here. And they need to possess people to move around unnoticed, and do what they have to. There's one demon, named Lilith, who's trying to raise Lucifer. She has minions to do what she asks. Right now, they want us. If they posses us, they get our abilities. In the case of people from our world, full control of our magic, and access to our memories to know all the spells." she explained, looking straight as him as she did. It seemed to calm her down, colour returned to her face, she became more focused. "You need a necklace. It's a charm, to prevent possession. I've learned how to make them, I'll get you one."
She looked down at the body, wincing slightly at the sigh of it before turning away. "Right. Lets do that then. At least we know it's her for sure now."
Not saying anything was probably best, either way, she didn't like the sound of things.
