As the demon explained his terms, Shae was busy working on making herself a sandwich and taking some kind of cleaner to her arms that took the 'tattoos' off. It seemed they weren't so much tattoos as Henna... well... most of them. Some really were permanent, like the ones protecting her from influence and possession. The rest were removable with the correct chemical. She ate her food and glanced up at him when he finished, pushing aside the empty plate.

Though she'd seemed like she wasn't paying attention at all, she'd actually been listening carefully to his wording and his terms. She considered, "What kind of demon are you? If I'm going to be sharing myself I need to know what exactly I'm sharing it with and what the consequences might be."

The thing is, if she were sharing herself with a lust demon or a wrath demon there could be some serious problems... Well, if you considered promiscuity and the occasional blind rage induced murder a problem. She drummed her fingers on the counter before continuing, "Also... I have some stipulations. If, at any time, I find you are reporting my knowledge to another... be that other be demon or angel, or purposefully impeding my cause... The contract is then null and void."

She smiled somewhat, "Because the things I know are valuable to both sides and I don't need a demonic informant inside my brain... deal?"

She stood and moved to her cabinet and removed ash and salt... "I'll help you stay put without that body until the contract is made, if you still want to make it?"

She drew a circle in ash and then an intersecting circle with the salt. With her chalk she drew runes on the outside of each circle that warded her from malintent and prepared it for a contract and the 'joining' rune in the area where the two overlapped. It was a simple set-up designed to force the two of them to state their deal whilst joining hands over the overlapping bit and the magic between them would hold them both to the terms. It would also protect her from any trickery because it wouldn't allow him to do anything but what he stated... it left him vulnerable though because she could dismiss him if she wished and force him to go back to his possessed body or find a new one. Unless, he was a more powerful demon in which case him being allowed to stand in front of her in his true form might be... unfortunate. It was a set up that Ruben had taught her so that even if he wasn't what he said she'd have some measure of protection against attack.

Usually, to make a contract, you used a summoning circle that was carefully prepared, but that was more for people who had a specific demon in mind... You could also just head to a cross-roads and hope some lingering demon decides to take an interest and then you're left open to all sorts of things like possession, their influence, or twisted words or... Well, not so great stuff. Shae was a bit too old school and way too cautious to just jump into any kind of bargain. 

"Ready when you are," she noted after scribbling two runes onto her arms with some paste that seemed to dry quickly and stain her fingers. They were for mental fortitude and courage because seeing a demon in its true form, or an angel for that matter, could be a... startling thing.
