The next day, Katherine walked to school.

From the moment she had woken up she was certain that it wouldn't be a good idea for her to be around Monroe with the level of blood lust that coursed through her. But she also wanted the guidance counsellor to have to look her in the face. To feel the her panic when she realised that Katherine Claudia Stilinski knew full fucking well what had happened the previous night. What she had done.

When she realised the Sheriff's daughter could pin a double homicide on her with just the snap of her fingers and a handful of words. But she wasn't going to do that, because the mental torture of what she could do would be infinitely better than Monroe having that answer. She wanted Monroe to suffer just as much as she was going to for the rest of her life.

So she dressed herself in a loose T-shirt that she paired with a hoodie and comfortable jeans, then put her shoes on and began the walk. She brought a coffee in her travel mug and didn't even care when she overfilled it and the liquid burned her hand. She just rinsed it off, and went out the door.

She didn't see anyone on her way to school, which was a blessing on its own.

People were the last thing she wanted to deal with right now. The closer she got to the school the more angry she felt until she was standing at the front doors and all she could feel was that calm, simmering rage bubbling beneath her surface because Brett and Lori were fucking children. Children who had been born into a life of danger and violence, but had the courage to try and become more than that.

And they were murdered for it. They had been murdered in cold blood by someone they were supposed to be able to trust, who was supposed to be advocating for them. A guidance councillor was meant to be helpful to students in figuring out who they are and how they could navigate their lives in the beginning of their independence. They weren't supposed to get away with murder.

So Katherine calmly pushed the front doors open and stalked inside. She shoved past the other students without giving a shit that they were snapping at her for it. But slowly, the vocal threats stopped.

By the time she was at the end of the hallway the majority of the students were staring at her with something that once would've made her feel extremely guilty; fear. They were afraid of her because they had heard about Liam becoming a monster with glowing eyes at the scene of a car accident. A car accident where two people, one of whom was a school rival, had died.

That only angered her more. She slowly stared each of them down until they looked away, and then went about her business.

She found Liam and Mason standing at their lockers, both of them jumping when she cleared her throat from behind them. Apparently she had been quieter than intended. "They know," was the first thing Liam said to her, panic scrawled across his face.

"Just rumours," Mason shook his head at him before she had the chance to speak. "They don't know anything."

"They know everything," Corey cut in, stopping his abrupt walking pace beside her. There were two sophmores on the lacrosse team there last night."

Mason grimaced. "Yeah, but...it was late, it was pitch black out, there was fog on the road..."

"It was a clear night, the full moon was out and it was a well-lit intersection," Katherine cut in, jaw clenching with muted rage. "Anyone could've seen...hell, they all saw me holding two dead bodies in the middle of the road."

It wasn't that she was angry with Mason, because she honestly wasn't. She was just angry, and he was trying to make the situation seem better than it was. It wouldn't help any of them.

"I have to get out of here," Liam hissed, anxiously reaching out to grab her hand.

She gave it a squeeze.

"You can't," Mason shook his head rapidly. "If you leave, these rumours are never going to stop. If you just convince everyone you're a regular kid—"

"—I'm not," Liam cut him off quietly. "I'm not a regular kid."

"Remember what Scott said?" Mason huffed. "Be Clark Kent."

"Clark Kent?" Katherine demanded with a snort. Liam then went through the quick explanation of Scott telling him that werewolf-Liam was super man, a hero to all, and Liam-who-goes-to-school was Clark Kent, a regular guy with a regular day. "Yeah that sounds like Scotty," she muttered drily, though her fondness for him warmed her a little bit.

"Clark Kent turns into a guy in a red and blue outfit with a cape," Liam then snapped rhetorically at Mason quietly. "I turn into a monster with claws and fangs."

"Then just get through the day without shifting," Corey cut in to defuse the tension.

"People are saying Brett and Lori died in a car accident," Mason told them all quietly, glancing down at Katherine's hand as it automatically curled into a trembling fist. "We know what really happened, the truth. They didn't just die..."

"They were murdered," Katherine spat out for them, knowing none of them wanted to be the ones to say it.

"Yes, they were," Mason agreed softly. He settled a hand over her shoulder and gave it a gentle squeeze that almost made her cry. "And now we have to prove it."

The bell rang to signal the students to make their way to classes. Katherine grabbed Liam's hand and held it for a moment before stalking down the hallway, not in the mood for words. The others in the hallways moved off to the sides for her, all staring with narrowed eyes and faces twisted into disgust.

She was stopping at her locker to grab her English text book when she saw movement out of the corner of her eye, and turned to look at it. Monroe was standing frozen at the other end of the hallway, staring at her with a blank face.

In that moment, Katherine wasn't a person.

She wasn't the teenage girl grieving for two of her best friends, who had held them in her arms as they both died.

She wasn't the sister of an in-training FBI agent, or the daughter or the Beacon Hills Sheriff, or the girlfriend of the lacrosse team captain.

All she was, was rage.

One of the first memories she had as a child was herself chasing Stiles down the hallway of their home. She was four years old and had made the mistake of giving her favourite Barbie a haircut so he could pretend it was a different character, since he didn't have that action figure.

Katherine had screamed as she'd run after him, ignoring both of their parents who came in to interfere. She paid no attention to their calming words and had charged at her brother, and had scratched his arm so hard he bled.

Naturally that had ended in Stiles crying, her crying harder over her barbie, and her father having an incredibly long conversation with her as to why you can't scratch people when you get upset. Stiles had gotten in trouble for what he'd done to her barbie and while she didn't remember what happened after that, she remembered feeling like something had been taken from her.

What she felt now was like that, only amplified by thousands.

Very slowly, with that lethal calm flooding through each nerve ending in her body, Katherine walked down the hallway. The other students had all gone into their classes now and it was just the two of them out there.

Monroe was taller than her in the heeled boots she always wore, but her face had gone pale at the sight of her.

She stared up at her, jaw clenching, as she rose up onto her tiptoes until she was close enough to whisper, "I know what you did."

The sharp inhale was all she needed to hear. Monroe was staring at her with her mouth slightly open, and Katherine relished the fear that she saw in the woman's eyes. It was better than anything she could've imagined.

She didn't wait for an answer as she turned and walked back to her locker, grabbed her textbook, and then turned down a different hall to go to class.

•••••

Katherine spent her lunch break going through the photos on her phone, pausing sadly over each one of Brett and Lori. She had spent ten minutes on the phone with Scott, who explained that they were thinking Gerard Argent was the more experienced hunter in the situation, and in turn she told him who she thought the protegee was.

He told her that him, Lydia and Malia were going to try to come up with some kind of deal that Chris would then present to him, as they figured out of the four of them that Gerard was least likely to kill his family. Not unlikely, just least likely.

Around her, other students were going about their day as they usually would; gossiping, eating, complaining. But none of them would allow themselves to be caught looking at her. Katherine knew that it wasn't entirely their fault, that just because they were afraid didn't mean they were bad people.

But how many of them thought that what happened to Brett and Lori was their fault because of the fact that they were something other than human?

She had been sitting there when Liam came to find her. He sat down, sat his head on her shoulder, and told her that he had resigned as the team captain. Katherine gaped at him, demanding why, only to end up hugging him when he explained that the team had called a secret meeting to vote him out because he wasn't human. "You mean to tell me that Nolan — the kid I literally saved from a wolf — is trying to be all high and mighty and popular and hunter-y? To you?" She demanded.

Wordlessly, Liam nodded his head.

"You guys okay?"

She glanced up at the sound of Mason's voice and her gaze drifted off to the wall as Liam explained what had just happened with the lacrosse team. For the duration of it they stayed at that corner table going over everything until finally they left the cafeteria.

They were just reaching a turn in the hallway when Corey cut them off, shoving them off to the side of the halls. "I overheard Nolan talking to Gabe—"

"—who the fuck is Gabe," Katherine demanded.

Apparently, he was someone on the lacrosse team and had been the guy backing Nolan up with the decision to boot Liam out of Team Captain. She hated him. Admittedly she had no idea who he was, but he seemed hatable. The name was reason enough to dislike him.

"You were spying on him?" Mason hissed.

Corey stared at him for a moment, the look on his face reminding her a lot of her brother for a brief moment. "Since he stabbed me with a pen, yeah."

"A respectable reason to stalk someone," Katherine hummed.

The three of them turned to her, all looking mildly concerned, before Corey continued with just a shake of his head. "They're going to try to make you shift." His words were directed at Liam. "He wants proof, and he wants everyone to see it."

"Well how's he going to do that?" Liam gaped at him.

"I don't know, that's all I heard."

"Could you stop obsessing over what people are saying about you," Mason groaned.

Then, Liam choked out, "Nolan's coming," and she blinked.

The three boys shuffled behind her for a moment before she heard the door behind them drift shut with a click. "That settles it," she muttered, and grabbed her bat.

Immediately Corey had an arm wrapped around her shoulders, using his supernatural strength to keep her in place while Mason was hissing about not being allowed to beat people up with a baseball bat during school hours or regular hours or any hours.

Then, from the opposite end of hall, Nolan Holloway with his stupid '08 Justin Beiber haircut and black skinny jeans came around the corner with a taller tanned kid dressed similarly. She was willing to bet that was Gabe, and he was definitely hatable.

Katherine stared at them as she flipped her bat in one hand, first catching the handle and then the opposite end before repeating the pattern. After doing that another few times she kept the grip in her hand and swung the bat around, almost hitting Mason with it. She would apologise later.

For now, she had teenage boys to scare.

Both of them were watching her with arms folded over their chests, staring like they were waiting for her to look away first. When she didn't, their eyes narrowed.

"I don't scare that easily, boys," Katherine called out to them drily, which caught the attention of the other kids in the hallway. She began twirling her bat again.

Slowly, they dropped their arms. She landed an elbow in Corey's side which startled him enough to drop his arm. She used that to her advantage and took a few steps forward.

For two teenage boys they were decently smart because both Nolan and Gabe seemed to then recognize her as the threat she was, and back off. They disappeared around the corner.

Not a minute later, Liam ducked out of the door behind them and Katherine turned to look at him, the lethal calmness in her swelling when she realized he had hidden in Monroe's office. "She had books on supernatural creatures stacked on her side table and scratches on her neck that are from a tree branch in the woods," was the only thing he said, his voice low.

"I fucking knew it," Katherine snarled. Her grip on the bat tightened so intensely her knuckles turned white.

She went on to explain that she had seen Monroe standing with Gerard on the side of the road that night, both staring at her with a similar expression.

The boys had to all but drag her down the hallway again, Liam having snatched his bat as he texted Scott the information they had, but Katherine could only stare at the guidance councellor plaque on the door.

I know what you did.

I know what you did, and I'm going to make sure you pay for it. Even if I have to pay for it too, you'll get what you deserve.

I promise that.
