"Pupils dilate under normal conditions" Deaton said, clicking the torch. "Heart rate is 250" he pulled her shirt down ever so slightly. "Evidence of an allogeneic skin graft on the right shoulder. Now, this silvery substance at her lips is not something I've seen. It almost looks like mercury"

Tracy's body jerked.

"Can't you just give her a shot of something?" Malia asked.

"She doesn't look to be in any pain" Deaton said.

"I meant a shot to kill her"

"I generally prescribe to a code of ethics that frowns on such measures"

"Malia, you know we're not going to do that" Scott said.

"How do you know she's not going to kill us?" Malia questioned.

"She makes a decent point" I defended.

"Either way, eventually I'm going to have to let my dad know she's here" Stiles said.

"Agreed" Deaton nodded. "And while I may argue against euthanasia" He picked up a jar of mountain ash. "I'm not opposed to a little extra security"

"Don't worry, Tracy won't be able to cross a line of mountain ash. She's not going anywhere" Deaton said, obviously noticing our anxiety.

"Yeah that's kinda of what I'm afraid of" Stiles said.

"Well, you, Kara and I will be able to get out of here no problem. You two-" Deaton looked between Scott and Malia. "-not so much"

Malia frowned, looking down at the line of mountain ash on the floor.

She put her hand out but it was unable to pass through. "Weird"

"Scott would you mind holding her down?" Deaton instructed. "I'm going to be trying a few more invasive tests"

I watched as Deaton slowly slid the surgical knife down Tracy's skin, yet it didn't cut her. There wasn't even a scratch.

I heard a cracking sound and then Deaton held the knife up, examining it with a confused expression.

Stiles looked up. "I think you're gonna need a bigger blade"

"Now this is interesting" Deaton commented, as he looked down at Tracy.

Malia and I walked closer but I paused when I noticed her skin moving.

"Malia help me turn her over please" Deaton said.

Mals and I turned Tracy over and the three of us stared at her in disbelief.

"I think I know what she is" I heard Stiles say.

"Care to enlighten the rest of us? Because this doesn't look too good" Deaton said.

The boys walked over and I watched their confused expressions in slight amusement.

Tracy's spine seemed to start moving and Deaton pressed his hand against it, whilst I stepped backwards in fear.

Suddenly, her back split open, spraying blood everywhere.

We all stepped forwards, trying to see what had happened. I gagged and turned away at the sight of what seemed to be a growing tail emerging from inside of her.

Then there was the sound of something whooshing through the air.

Stiles let out a yell and I spun around just in time to be hit by Tracy's tail.

My body fell to the floor and I cursed.

I couldn't feel my limbs at all.

I knew what she was, though. The boys had given me a Bestiary book to help give me a better understanding of the supernatural.

"It wasn't a werewolf" Stiles yelled out.

I groaned in frustration. "Bitch was a kanima"
