- Kira: You're going to tell Scott that Barrow might have used foxfire created by me to jump start the Nogitsune's power inside Stiles.
- Derek Hale: Yeah.
- Kira: Basically that I helped the dark spirit take control his best friend.
- Derek Hale: You should probably wait here.
- Nogitsune: You don't understand, do you? It's a riddle. Do you know any riddles, Stiles?
- Stiles: A few.
- Nogitsune: What gets bigger the more you take away?
- Stiles: A hole.
- Nogitsune: What gets wetter the more it dries?
- Stiles: A towel.
- Nogitsune: When is a door not a door?
- Stiles: [Anguished] When it's ajar.
- Aiden: I kinda overheard... well I listened in on Stiles talkin' to Scott about how he thinks he was the one that wrote that message to kill Kira.
- Derek Hale: You think Stiles, skinny, defenseless, Stiles, is the Nogitsune? A powerful, dark spirit?
- Mrs. Yukimura: You know me. Then you remember that I won't be deterred by your choice of host. Even if it's an innocent boy.
- Stiles: [Possessed] Are you threatening us?
- Mrs. Yukimura: [the Oni appear] Now I'm threatening you.
- Stiles: We're not really afraid of your little fireflies.
- Mrs. Yukimura: If the oni can't defeat you, I know someone who will.
- Aiden: Are we even allowed to be here this late? What if security catches us?
- Lydia Martin: There is no security. The number of the homicides in this school have seen to it that no sane person will ever take a night job here again.
- Lydia Martin: [In Stiles' bedroom] There's something here.
- Isaac Lahey: Yeah. Evidence of total insanity.
- Derek Hale: There was definitely some kind of a struggle.
- Scott McCall: With who?
- Derek Hale: Himself.
- Lydia Martin: What did that sound like to you?
- Aiden: Like a string being pulled.
- Lydia Martin: You didn't hear people whispering?
- Aiden: I definitely did not her people whispering.
- Scott McCall: How did you know? Did he call you too?
- Lydia Martin: I heard it.
- Aiden: Don't ask. It gets more confusing when you ask.
- Rafael McCall: We get a lead on our sword-wielding maniac?
- Deputy Parrish: Nope. But we've got posters up all over town for your guy.
- Rafael McCall: [Looks] Not exactly how I described him to the sketch artist.
- Derek Hale: You know, I took Cora back to South America, right? It's where she spent most of her time after the fire. But that's not the only reason I left. I needed to talk to my mother.
- Scott McCall: Your dead mother?
