Stiles becomes aware of his surroundings again at some point, but he has no way to really estimate the time. Last event he is sure he remembers was in Beacon Hills Memorial Hospital. Checking his phone for the time, he saw 5 missed calls. They were all from his dad, but there was only one voice mail, where his dad just asked where he was. Not really thinking about it, he sent off a text that read "Am ok. Please don't look for me. Be back soon." He didn't want his dad to be using police resources to search for him when he was okay. His surroundings fade to black again and Stiles is gone, still unsure of where he is.
In this void, Stiles doesn't know what is happening, but of course he isn't sitting still. The fox spirit inside of him is too busy causing trouble. The Nogitsune moved through Beacon Hills like a predator, never being seen by any of the people who would be looking for Stiles. There were several spots that needed to be reached before too long. Some things, like the bomb, had been prepared and was already in play. Now to really create some chaos.
He traveled across town to the Argent's house, where he knew Chris had locked up his hunting equipment. Stiles knew he wouldn't get caught, even with Chris' experience hunting those supernatural creatures. Of course it didn't matter, because no one was home. He broke into the office, and then into a cabinet. Inside he put the metallic silver briefcase that had been turned down when the Argent's and Isaac had met with Katashi. They didn't know he was there, but then again they never did. He pulled two ultrasonic emitters from another shelf and headed out, leaving just one more surprise on the little table in the hall.
He traveled off to the loft that Derek was now living in, and left one of the emitters just outside his door. He turned it on before walking calmly down the stairs. He didn't particularly care if Derek caught him on his way out, in fact if he got caught it would be even better. Fighting was chaos, and chaos was his favorite thing. Unfortunately Derek didn't appear, so Stiles just continued on his way. Here was where the real fun would begin.
He snuck into the school and into the basement where he set himself up with the other emitter. After turning it on, he settled in to wait for a couple werewolves to appear. While he was waiting, he put in an anonymous call to the police station, asking them to tell Agent McCall about what was in Chris Argent's apartment. He made it quick, figuring Scott and anyone else would not keep it waiting. They didn't disappoint. Just moments later Scott, Ethan, and Aiden showed up in the basement. Scott looked in shock to see Stiles standing there, not only because it wasn't Chris, but because he thought Stiles was back. He would be so sad when he found out what was REALLY going on. Before he could say anything, Ethan and Aiden jumped on him and started fighting. Before they could get too far though, Scott pulled Ethan off, flinging him into an old locker and then turning to Aiden and growling until he actually backed off. The twins were both arguing with Scott, saying that they should be calling the police to say they found Stiles. Scott says no (as Stiles had hoped) and says they have to find out what is going on first. Only then does Stiles speak, sharing with them that he didn't know what he had done for the past two days, and that was true for the real Stiles, but this certainly wasn't him. He pulls out his meticulously filled bag, showing them what there was. He showed them the blueprint of the hospital's electrical grid first. He had figured that that would keep Scott quiet for a while, and therefore everyone else. After that he pulled everything else out; the wire, the rope, assorted tools, and then the map of the cross-country running trail. He had picked this trail for the fact that it was along were Malia Tate's father had set out the bear traps meant for the coyote. He could tell he had made a good choice when he saw just a little flicker of shock in the werewolves eyes. They believed the Nogitsune had used some of these to cause trouble on the trail. All four of them raced outside to stop the team.
At the start of the trail, all they could find was Coach Finstock, and he was definitely not happy that the three of them had disappeared. His face changed to shock when he saw Stiles walking behind them, but before he could ask, Scott started talking about the potential threat on the trail. It of course wouldn't be easy to catch them all, they could only hope that they hadn't run too far yet. Ethan and Scott disappeared quickly, leaving Coach, Aiden, and Stiles to catch up with the larger group. When they finally managed to catch up, and stop the larger group, Scott and Ethan were already heading back with Danny and Kira. Stiles can see the confused looks on the rest of the teams face when he yelled stop before the group could come entirely together. There was a chain under several leaves, but of course Stiles knew what it would lead to. He pulled the chain up slowly, enjoying the increasing worry that was radiating off of everyone around him. When he got to the end, of course there was nothing there, and Coach started laughing, believing that this is all just a normal Stilinski joke. It is Coach who hits the tripwire that was the true trap, and before anyone could blink there was an arrow sticking out of the Coach's stomach. Most of the team started freaking out, while some just stood there shocked. Stiles stepped forward to "help" first, and was pretending to put pressure on the wound, except he was actually pushing on the punctured diaphragm. Soon there was a large spread of blood over the Coach's shirt, and he was having a hard time breathing. Someone had called an ambulance at some point, he could hear the sirens coming in the distance, and he looked to Scott. Scott seemed to realize what he wanted because he quickly grabbed Coach's wrist and took some of the pain. Stiles could see that Scott was frustrated because it wasn't having the same effect as it usually does. The ambulance arrived and with it came the Sheriff. At the sight of Stiles, Sheriff Stilinski stopped with wide eyes. Keeping up his charade, Stiles headed over to see him. Stiles and his dad stood hugging and talking for quite a while, before they were dragged apart by another turn of events.
Aiden had found the wrapping paper that was in the back of Stiles jeep, and with everyone remembering what William Barrow had done with his bomb at the other school, another panic began as everyone tried to get back to the school. By the time the team got back to the buildings Deputy Parrish was standing by one of the buses with a certain look on his face. Stiles knew that they had found the present he had left for them. He could just hear Parrish telling his dad that a kid was sitting on the bus, holding the present in his lap. Stiles was not 100% sure of how they would handle the situation, but to his excitement, Parrish decided to step in and get on the bus. A large crowd was surrounding Stiles and Scott, and he could taste the panic in the air. He was completely ready to drop his charade, but he wasn't done yet.
He can see that his dad is relaxing when he receives the radio call from Parrish. They know it isn't a bomb, just something else. The panic started dissipating when Parrish returned to the front of the bus holding something up to front window. The rest of the group probably couldn't tell what it was, but Stiles knew exactly what is was. It was his father's nameplate. His father could see it too, because there was a huge wave of fear running off into the air. Stiles can see it on the Sheriff's face when he realizes where the bomb must be. It was only a few minutes before they were on their way (the Sheriff not letting his son out of his sight) to the police station.
Even with the warning, the police station was wrecked on the inside. Just at the doorway, Stiles could already feel all the emotions that were running rampant around the station. With just one whiff, he found the remnants of the original fear, but now it was mainly just panic and pain, sometimes both. Inside his dad had rushed off to help where he could and Stiles and Scott were left alone with what was practically the rest of the station. He nodded to Scott again and they both headed off to help the people they could with pain. Scott had pulled a little pain from a few people, but again he was frustrated because it wasn't working as well. Finally, there was one officer they reached who while Scott was taking his pain, died. Even with the death, Stiles could feel the frustration, sadness, and hurt rolling off Scott in waves. Stiles took some of that, but he wanted Scott to have as much pain in him as possible, his plan was still not done.
Once Scott works with a few more people, Kira shows up and tells them that Oni are coming. Scott gets nervous, because he knows they will be after Stiles. He is the only one left. Pulling both Stiles and Kira out, Scott heads to the vet's office. Stiles hadn't known where Scott was planning to take him, but he could make the Vet's office work. The Oni caught up with them, of course, before they could get into the building. Scott's need to defend Stiles jumped ahead and Stiles just stood in the background, enjoying the struggle he could feel coming from Kira and Scott. At some point Kira managed to get a sword and kill one of them, and the tide turned a bit, but not enough. Scott got a sword through his stomach for all his efforts, and Kira and Stiles hurried to get him inside. Inside they were safe from the Oni, and any wandering eyes. Stiles and Kira lifted Scott up onto the table, and then the moment came. Stiles stopped pretending to be the real Stiles and smashed Kira's head into the metal table. As she fell to the ground, Scott stared at him, with confusion spreading in the air. When Stiles turned back, Scott had pulled himself up and standing in front of the table. Stiles grabs the hilt of the sword, and instead of pulling it out, he pushes it further and twists, worsening Scott's wounds. Stiles knows that Scott is still confused, and so he explains. He explains about how the Nogitsune likes to feed off pain and misery and the emotions like that. He finally reveals the finale of the plan, when he tells Scott how he has manipulated him to soak up all of that pain today, and how he would feed off it and strengthen himself again. Stiles lifted his hand to Scott's head and started pulling all the pain out, it traveling down his arm like it had traveled up Scott's originally. He takes it all and gives a wicked smile. "You never should trust a fox. They're tricksters and they'll fool you. In fact, they'll fool everyone." All smiles, Stiles hears a voice behind him. "Not everyone." and before Stiles can do anything, something punctures his neck. He can feel the injection coming in and then the burning feeling as it runs through his blood. He knows what it is then. Letharia Vulpina. The wolf poison. With that thought he fell to the ground, fading into the same blackness as the real Stiles.
