Kira let out a breath, not letting herself panic. She'd thought they were pretty much the same thing too once, having been convinced she was the evil thing the Oni were hunting. "We're both foxes." she explained. "But Nogitsune's are dark. Also this is my body. Born this way. The Nogitsune possesses people." One was good, one was bad. She wondered if she still had the mark from the Oni, but it hadn't occurred to check for that again once they were gone.
Where had he come from? Kira hadn't heard a sound, had no idea he was there, no warning. One minute she wanted to talk about Stiles, and then he was right behind her. Only it wasn't Stiles. Not really. He was likely still there, probably still in the same body, but he wasn't in control right now.
"I'd be happy to deliver some good news." she said, not daring to look over her shoulder. "The goods news is that you can stop him." she said to Scott. "You can save Stiles. The Nogitsune can be defeated." Her tone was defiant, a 'go to hell' message for the Nogitsune delivered in her words.
Kira didn't move, his grip on her arm keeping her very still. He was powerful, one wrong move and he could easily hurt her. A Nogitsune at her back, and one angry werewolf at her front. Perfect. This was exactly the situation she wanted to be in. "Scott." she said carefully, still not moving. She really, really hoped he was still capable of being rational. "Scott he's still in there. Stiles in there, you don't want to hurt him."
