Stiles Stilinski x Fem!reader

Part 12

"Isaac, stop touching things." I scolded him for the second time and pulled his hands away from the counter, shaking my head as we stood in the animal clinic with Derek, Scott and Deaton. Speaking of, Deaton looked over to me.

"Well done on making Beta, (Y/n)." I smiled in thanks and swatted Isaac's hand away from the bottles again.

"Thanks. It's nice to not rely on people all the time."

"So, does the kanima show any weakness?" We all shared a look, Isaac leaning on the table on his forearms.

"One." Derek spoke. "It can't swim."

"Does that go for Jackson as well?" Scott shook his head.

"No. He's the captain of the swim team." I thought for a moment.

"Maybe it's sort of psychological, it's not the kanima that can't swim, but the master. Like a link between them?" Deaton slowly nodded, knowing my theory was completely plausible.

"Essentially you're trying to catch two people." He got something out of one of the drawers. "A puppet and a puppeteer." He set it onto the table, it was a pendant. "One had to take care of the husband and the other the wife. Do we know why?"

"I don't think Jackson could do it. His mother died pregnant, too, and she was maybe murdered." Scott added and I looked at him, knowing he was right. "I think he couldn't let the same thing happen to someone else." I noticed Isaac's change in behaviour, like he had realised something.

"Isaac? You okay?" He shook his head and then nodded, his one arm slipping around my waist and pulling me next to him.

"How do we know it's not part of the rules?" I stared up at him.

"What?"

"The Kanima kills murderers. If Jackson kills the wife, then the baby dies, too."

"Does that mean your father was a murderer?" Isaac's grip tightened on me a little but soon relaxed.

"Wouldn't surprise me if he was."

"Hold on, the book says they're bonded right?" Derek nodded. "Then (Y/n) could be right, what if the fear of water isn't coming from Jackson, but the one controlling him?"

"What if something that affects the kanima also affects its master?" I added, letting my hand wander to the bottles and pulling out the one with mountain ash. "We could trap them both."

"Wh-what is that?" Isaac asked from beside me.

"Mountain ash, it acts as a sort of supernatural barrier." I explained and stood up straight.

"So we can catch them?" I nodded.

"Theoretically."

I followed Stiles into the room where Erica and Isaac were keeping Jackson, the two of them flinching when the door opened, but relaxing when they realised it was us. I watched as Isaac had his arm twisted before he came back over to the three of us and sat on the sink that was in the corner of the room. I set my hand on his shoulder.

"I'm here, I'm right here with you." Jackson's voice was distorted, not like him, and it was freaking me out, it freaked all of us out.

"Jackson." Stiles crouched in front of him while u s three werewolves chilled in the back. "Is that you?"

"Us. We're all here." Stiles looked back to all of us, Erica edging closer to the two of them while Isaac pulled me over to him when I trued to do the same.

"Are you the one killing people?"

"We are the ones killing murderers." I shared a look with Isaac.
