[laughs] I wasn't going to tap you on the forehead. But... The sword is a gateway to the Fox. And the Fox is too dangerous. [He sighs] Your mind is a weapon, Kira. Trust yourself. You can still outfox the Fox.
There's a story. I don't know all the details, but something happened a long time ago. Somehow, she lost part of her power. She's not as fast or as strong as she used to be... But, she can still pull a trigger, and she's a perfect shot.
[exasperatedly] And why do you think it's been years? Because she knows what she's doing. She took Scott's boss for a reason. We don't know what it is. We don't know if she's back in Beacon Hills because she missed you all this time and can't wait for a mother-daughter reunion, or if she's planning to put a bullet in your head. We don't know anything.
Everyone. Everywhere. I was in chemistry class when it happened. I had my hands over my ears. My teacher was trying to figure out what was wrong. I took my hands and I started hitting the desk... until I couldn't take it anymore, and I screamed.
All of the windows shattered. I saw kids with glass in their arms, in their faces. Some of them had blood coming out of their ears. They said it was an explosion caused by chemicals... but everyone knew it was me. Find a better way, Lydia. My voice is like a bomb going off. Yours needs to be a bullet.
Your teachers, uh, gave us some of the stuff you guys have been working on. They wanted us to hold onto it for you. I saw something about the, uh, Riemann Hypothesis. Um, things like... nontrivial zeros, zeta functions, and a lot of other stuff that goes totally over my head. Maybe you can wake up and explain it to me? [Stiles hesitates and sighs] Oh, come on, Lydia. You have to come back to us. There's no way we're getting through this without you. Lydia, you have to wake up.
[sighs] Back at my old school, at Devenford... I got into a fight with this kid. I knocked two of his teeth out. They made me write a letter of apology. We both knew it meant nothing. We both knew that sooner or later, we're gonna get into another fight. I can't just say I'm sorry. I feel like I have to do something. Like, maybe... somehow... I have to save your life.
[Scott and Liam have just found Argent hiding in the Dread Doctors' laboratory. Scott senses Gerard's presence and gives Argent a hilariously disappointed look]
The Hellhound. The guardian of supernatural places. They're both creatures of the night. But you may know them as ordinary creatures during the day. And, most likely, neither of them know what they are.
