"If you want to help me once I find it, I won't stop you. How can I contact you?"

Trevor gives her an e-mail address. "I might have a proper cell number in a few days. Do you have anything in case I need to contact you?"

"Meet me at the local library. If you go there, I'll meet you."

"Perfect. Anything else or can I proceed with my morning flight?"

"Enjoy." 

She stalks off.

And Trevor flies off in search for Scott or the nearest relevant person.

Theoretically, some of the relevant people will be in school. Sky might be easiest to contact.

Sure, Sky works, he will find Sky and say. "Hey, some mysterious fox-lady told me that one or all of the three Nemetons sacrifices might be possessed. How was your night?"

"Hello to you too. Do we trust the mysterious fox lady?"

"Well, there is that saying 'trust but verify' which I guess works even when you don't trust people," he then relates his conversations between himself and Noshiko.

"She didn't say anything about weaknesses? Does mountain ash work? Who needs to be that cryptic, is it a pathological thing?" 

"She didn't even say anything about powers, actually. She did say that mountain ash works, but only when it's outside a host. I honestly don't know what the deal with the crypticness is. Might be a kitsune thing. And maybe this is just a prank, but I think it's worth telling the others about it."

"The part where they feed on chaos and pain is kind of weird, most monsters around here are all about violence and vengeance, but they don't like it. They just can't help it." 

They go to meet up with the others.

"I honestly don't know what to expect as normal from the local supernaturals."

Where they meet the others? Who is there besides the three sacrifices?

One of the sacrifice's fathers is there as well.

There's also this guy.

"What's this about?"

"Sky said that Trevor has news for us about our situation."

"Lay it on us."

Cool. He tells everything the kitsune told him (he decides not to share her name with the know hunter of supernatural creatures).

"So, Scott, Stiles and Allison are totally possessed by an ancient chaos spirit and there is a fox-woman hunting them down. How do we solve this problem?"

"We get it out. Mr. Argent?"

"I may have a lead. I'd rather not discuss it in front of any nogitsune."

"Who are you going to discuss it with?"

"Lahey. Doctor. Newcomer. We should talk, without them."

Blink.

"I didn't know we were friends."
