"Delilah!" My sister yells, a smile on her face. I run toward her. She stretches out her arms, and I hug her.

"I thought I lost you." I pull away to look at her. "What happened?"

"I got away."

I frown. "Tris, you sound different. Are you okay?"

"What do you mean? I'm fine!" She says as her eyes flash the bright electric blue of the djinn. I scramble away from her.

"Lil? Come back." She says, a demanding tone in her voice I've never heard before.I stare into her unnaturally blue eyes, searching for the brown irises of the sister I know.

"Tris." I say, my voice breaking. "Where's Tris?"

"I'm right here." The monster responds, cocking its head. Blue tattoos start to snake their way down its arms. "Come with me." It says. "We can be happy together. I can give you anything you want.

"N-no. You're not real. This- this is a dream." I realise.

"You may be in a dream, but this," It gestures at my sister's body, transfigured with the symbols of the djinn, "this is real. This is what your sister has become. And you let it happen."

"No. No no no no no." I back away, covering my ears. "No. None of it is real. It's not real." I trip over my feet and land on my butt. My sister-monster towers over me, every inch of her skin covered in glowing tattoos.

"This happened to her, and it will happen to you. You can never escape us. You think you can forget us, start over, but you will never be able to. We will always be there, waiting for you to let your guard down, so we can get in. You will never be free."

I wake up in a cold sweat. The first thing I register is a flash of blue, and my blood turns to ice. I relax as I see it's just the streak in my hair. I must have been sleeping with it in my face. That explains the dream.

I try to slow my breathing. "Just a dream, just a dream, just a dream, just a dream,"

The bedsprings creak above me. "Delilah?" I hear Nydia say through a yawn. "What's going on?"

"Just- just a bad dream." I tell her.

"Are you okay?"

"Yeah. Yeah. I'm fine." I take a deep breath. I'm not sure I believe myself.

Apparently she doesn't either, because I see her silhouette coming down the ladder. She comes and sits next to me.

"Do you want to talk about it?" She asks, her brow furrowed.

"Not really." I don't want to get into that with her yet.

"Okay." She puts her arm around me and lets me put my head on her shoulder. She starts singing a song in a language I don't know.

"Malagō malagenna mariye baṇṇada navilina gariyē, ellinda bande ī manege kaṇḍa nī iḷidante bhuvige.."

She keeps singing as I slowly fall asleep.

"Can anyone tell me how to kill a djinn?" Claire asks. I raise my hand. "Delilah?"

"Either blunt force, like bashing its brains in, or a silver knife dipped in lamb's blood."

"Exactly." She gives me a small smile. Over the past few weeks, I've focused excessively on how to track and kill djinn, so eventually I can find the ones that ruined my life and kill them.

Claire continues talking about the different ways to kill monsters and how they overlap, even bringing out some examples of weapons and asking everybody what each one could kill.

"Okay. Tomorrow, we're gonna get some practice using these weapons, so wear clothes you can move around in. Instead of coming to this classroom, you're gonna want to go down into the yard, where we'll have some stuff set up. Okay, everybody can go."

I start to head towards the door, but Claire tells me to hold up. She waits until everybody else is gone, and then starts to talk to me.

"I noticed how interested you've been in djinn lately."

"Well, yeah. They're the monsters that killed my family."

"Yeah. But that path can be dangerous. It can consume you, make you a monster yourself."

I raise my eyebrows. "How would you know?"

"Because a few years ago, I was just like you. I was obsessed with finding Castiel, the angel who ruined my life. I let it consume me, and when I finally found him, I wanted to kill him. I'm glad I didn't. I might not love Castiel, but I know he's done a lot of good for the world."

"Well, I'm certain that these djinn haven't saved the world multiple times."

She grits her teeth. "Maybe that wasn't the best example. Okay. Dean and Sam's dad, John. He spent most of his life trying to find the thing that killed his wife. He mistreated his children, he beat Dean, he kept them both from having a childhood."

"He sounds like a horrible person. I'm not."

"The thing is, he wasn't a horrible person before that. His need for revenge changed him. I just don't want that to happen to you. To anyone here."

"Okay. I just, I feel like those djinn deserve to die, y'know?"

"Of course. I feel like all monsters deserve to die. I just need to make sure that you don't throw away your life trying to find the exact djinn that killed your parents."

I nod. "Okay. Yeah. I understand. But I still just wanna kill as many of those sons of bitches I can find."

Claire smiles. "I wouldn't expect anything else from a hunter-in-training."
