Teen Wolf season 3, episode 18, “Riddled,” just finished airing. Read our recap and discuss the episode with fellow fans!

Teen Wolf season 3, episode 18, titled “Riddled,” begins with a phone call from Stiles to Scott, and we’re automatically thrown right into the situation at hand: Stiles doesn’t know where he is, he’s injured, and he can’t move. Scott and Isaac must rescue him.

Aiden and Lydia are in the school late at night, and she’s drawing him for her art class. Aiden has some notions of modeling nude for her, but before anything can ensue, Lydia hears Stiles’ voice coming out of the radio asking for help.

Kira is lying in bed doing homework. She reaches over to turn on her lamp, but the bulb is blown. However, when she goes to remove it, her hand sparks with electricity and the light bulb turns on and then explodes. Her mother comes in to change the bulb for her, and we see that the new light bulb also lights up when Mrs. Yukimura touches it.

Scott, Isaac, Lydia, and Aiden meet in Stiles’ bedroom. There are a pair of scissors embedded in the middle of the bed, with all the red yarn leading from the scissors up to his boards of unsolved cases. Lydia and Aiden stay behind to see if they can find any clues in Stiles’ room, while Scott and Isaac go tell Stiles’ dad that he’s missing.

Then, we get our first look at Stiles. He’s lying on the ground in a basement with his foot in a bear trap. A bandaged man is sitting in the corner, and he draws the symbol for “self” on the wall with chalk. But as soon as Stiles says it out loud, it disappears.

The sheriff is clearly upset, but he quickly gets his officers in crisis mode. They locate Stiles’ jeep, and find that it’s at the hospital. But it’s dead and Stiles is nowhere to be found. On the roof, Derek tells Scott that he can tell Stiles was up there and he was stressed as he struggled with himself.

Teen Wolf Season 3 Episode 18 Riddled Lydia 2

Lydia realizes that she can hear voices when she pulls on the red strings in Stiles’ bedroom. She finds out that Stiles is being held in the basement of the same mental asylum where William Barrow, the Shrapnel Bomber, was committed.

Back with the bandaged man, the creature tells Stiles he’s actually trying to save his life. Lydia, Scott, Aiden, and the sheriff show up at the basement of the mental asylum, but Stiles isn’t there. They leave, but the camera pans over to the wall, where we see scratches in the shape of the symbol for self.

If you’re wondering — no, we have no idea what’s going on either.

Melissa and Agent McCall team up to try to find Stiles. McCall thinks he’s still sleepwalking and that he only believes he’s in a basement. We get a little sneak peek of what their marriage was like, and it involved McCall having an apparent drinking problem. (Can you say hypocrite?)

Melissa and Agent McCall find Stiles in the coyote den, and he eventually wakes up screaming, obviously not knowing what’s going on.

Allison’s phone is turned off even though she didn’t do it herself. There’s a message on there in Japanese, and she and Isaac go to Mr. Yukimura to find out what it says. He translates it, saying that it’s a fake message about a Japanese internment camp.

Aiden tells Derek he thinks Stiles is the nogitsune. At first Derek thinks he’s being an idiot, but after a minute, it’s clear he thinks it could be a possibility. Back at the hospital, Stiles is fine, and Scott and Lydia go home because they have school the next day. Lydia hears some banging that no one else hears, but she ignores it.

Scott’s in a daze at school, and Derek shows up to tell Kira not to take it personally. Well, that, and to ask her what exactly happened at the power station. They go there so Kira can show him, and find Stiles’ bat is magnetized. Derek wants Kira to tell him everything she knows about foxfire.

Lydia is hypersensitive to sounds at school. Scott visits Stiles as he goes to do some tests. They’re looking for signs of frontotemporal dementia, which is what his mother died from. It’s when the areas of brain start to shrink. Scott is clearly upset, but he tells his best friend he’ll do anything he can to save him.

Derek figures out that Barrow used Kira’s foxfire to jump-start the nogitsune’s powers that was inside of Stiles. Derek relays this information to Scott, and also tells him that when he talked to his mother, Talia told him that the Hales not only lived in Beacon Hills, they protected it.

Scott and Derek go back to the roof, realizing that Stiles was trying to protect everyone from what he was about to do. They find equipment that makes it obvious Stiles was going to do something very similar to what Barrow might have done. Meanwhile, Lydia continues to hear the banging sound, and we find out that it’s the MRI machine Stiles is going through. She screams when she can no longer take it.

Back at the hospital, parts of Stiles’ brain show signs of atrophy.

In the machine, Stiles closes his eyes and is again transported into the dream-like state with the bandaged man. The creature once again asks him, “Everyone has it, but no one can lose it.” He tells Stiles that if he can figure the riddle out, then maybe he won’t kill everyone he loves.

Under that kind of pressure, Stiles tells the creature the answer is a shadow. That’s when the bandaged man unwraps himself…and we see that it is Stiles.

Back in the real world, there’s a power surge in the hospital, and with that distraction, Stiles slips away. That’s when Mrs. Yukimura shows up and confronts Stiles, who seems to be fully possessed by the nogitsune now. She tells him that she will stop him, even if it means killing an innocent boy.

Mrs. Yukimura makes the oni appear, but Stiles isn’t afraid of them. That’s when Mrs. Yukimura threatens to pull out the big guns. Too bad we don’t know who that is just yet.
