The Nuit had to hold herself from flinching when the ghost suddenly materialized and approached to touch her cheek. Things seemed to be going... alright. Well, as good as they could be, considering the original situation. And Isolde didn't want to mess that up. So she held very, very still.
She had heard that a ghost's touch was a chilling, unpleasant experience. The testimony had come first-hand from a man who had claimed to be a ghost-hunter while passing through Mithryn, where Isolde had grown up. He had been a melodramatic fellow with big bags under his eyes, a grin that could stretch for miles, and hands that waved and flapped about as he talked as if he was a baby bird not yet ready to fly. What Isolde felt when first Rena had touched her, and then Kouri, was just a slightly cool sensation, and it was neither pleasant or unpleasant. She wondered if having no body warmth altered her perception of the contact. Regardless, the cloak of coldness that seemed to radiate out from the girls still was enough to chill the warmth of Syna from the air, numbing the tips of Isolde's fingers and nose.
"You want me to be comfortable with you? I know just the thing... you let me go 'inside' you, Madame Isolde. That way... I can understand a lot more about your... body. Ehehehe~ So... what do you say?"
The Nuit just stared at Kouri --well, at the tip of her nose-- and let out a long, slow exhale. Okay, okay. She was suddenly very nervous. Let Kouri, the ghost girl who had just tried to kill her, possess her body? Isolde would have to be completely and utterly insane, raving mad to even consider it. It was a terrible idea. The risks... even besides the fact that the ghost had proven herself homicidal, Isolde did not know how this possession might mess with her body. Would it work like a normal possession --a topic Isolde already didn't know much about-- or would something else happen? From experience, she knew that a Nuit's connection to their body was... strained, for lack of a better word. The control was off a bit, the reflexes were off a bit, and Isolde had just gotten done thinking that even the way she experienced things, her senses themselves, were not the same as a regular, living person's. If a Nuit couldn't synch with their body, a lot of things could go wrong very quickly. And if Kouri --whether from malicious intent or by accident-- severed that vital, frail connection... what would happen? Isolde didn't know. At best, Isolde was willing to believe that the ghost wouldn't purposefully damage her, not after promising to Rena. No, no, certainly not. But accidentally was an entirely different matter.
The Nuit opened her mouth to say no --leaning back a bit because Kouri was very, very close, close enough that the Nuit could smell a faint odor of metallic blood-- but she found that she couldn't do it. What was wrong with her? She was not going to let Kouri do this!
But... but she had offered to do anything within her power. And this was in her power. If she broke this oath, then perhaps the ghosts would start wondering what other oaths --such as the promise not to hurt them-- she might break. That could make things very dangerous, very fast. Or perhaps if she angered the ghosts, both of them, simply by refusing? The Nuit flicked a glance at Rena; the girl looked so hopeful. And all of these threats and complications in Isolde's mind... they were all speculation. Just purely speculation. She didn't know how far-fetched her fears were, or how realistic. At best, nothing unusual would happen --well, other than her being possessed. At worst... her connection with her body would be damaged, or severed completely. She didn't know if she would be able to 'reconnect' or if she would be-- be broken. Unable to move. Crippled. And surely death would come after. If she didn't get into a new body, if she was unable to perform the soul transfer, then she would eventually rot away. Until she was gone.
But, once again, that was all guesswork. Probably everything would be fine. Probably.
Still, even if she did say no, what if Kouri decided to force her way in? Isolde didn't know if that was possible, but surely an unwilling possession would be a lot more damaging to her body, and possibly her mind. So either way, though she didn't really like the idea...
"I-If th-this is what it t-t-takes to make it up t-to you, then I-- I agree. Just, pl-please b-be careful. M-My body is... more frail th-than a regular p-person's." The Nuit gritted her teeth, not really knowing what was going to happen, or how it would work. Would she remain conscious of what was happening? Would it hurt? Would she be able to see into Kouri's memories? Worse yet, would Kouri be able to see into hers? Some emotion akin to panic danced in the Nuit's eyes. Her hands shook. But she simply sat where she was and waited for whatever was going to happen.
