"Get up." Klaus said as he pulled Rosa off of his bed.

She groaned, "No. Don't make me. I don't like them."

Klaus sighed and finally pulled Rosa up to stand in front of him. "They are your best friends."

The girl sighed, "How could they let this happen? Stefan held me back when I tried to stop Elena from burning down my house. My stuff. Jeremy's body." Klaus nodded. "How could they do that?"

"Look, I get you're upset, but some time has passed and I would like for you to come with me."

—

Rosa and Klaus walked into Stefan's house to see Caroline drinking out of a used plastic cup. "Desperate times, I take it?" Klaus asks, amused.

"What are you doing here?" Caroline asks, not even turning to look at Klaus.

"I brought a present." He said. Rosa nudged him, but he only shrugged.

Caroline turned around, and her mouth opened slightly. "Rosa? Hey."

"Hi. Looks like you guys threw some party."

Caroline looked around the room, "Not me. This was all Elena. And now she's mysteriously not here." Rosa nodded awkwardly. "So, why are you here?" She asked, looking mostly at Klaus.

"I was invited." He responded.

"By who?" Caroline and Rosa asked at the same time.

They watched as Stefan walked into the room, "Me."

Rosa rolled her eyes and turned to walk away when Klaus grabbed a hold of her arm as she tried to pass him. "Don't go, love." He whispered in her ear.

"We need his help. I think Silas might be in Mystic Falls." Stefan told them.

Rosa scoffed, "Can I leave now?" She asked Klaus. He shook his head and watched as she sighed with irritation.

The four of them walked to a cleaner part of the house and Klaus immediately went to pour himself a drink.

"So some blood went missing from a few hospitals. What about Elena? Don't vampires with their humanity off tend to overindulge in human blood, or were you the exception?" Klaus asks turning to Stefan.

He looks at Rosa who was frowning. "It's not Elena" Stefan said calmly.

"Well, let's say for a moment that it was Silas. I'm struggling to see how this affects me."

Stefan sighed, "Look. Silas wants to die and be reunited with his one true love, but he's supernatural, so if he takes the cure and dies, he gets stuck on the Other side."

"How Shakespearean."

"But if he destroys the Other side all together, he can take the cure, die and pass on, but in destroying it, every dead supernatural being will return to our side."

Rosa looked up, something like hope filling her. "That means every werewolf, every witch, every vampire. I wonder how many of those you personally killed. Care yet?" Caroline asked.

Klaus smiled, "My interest is piqued. How do we stop him?"

"We can't." Rosa muttered quietly. Klaus looked at her concerned, not sure if he had actually heard her.

Stefan then started to talk, making Klaus turn back his attention. "Bonnie said Silas needs to complete three massacres to do this spell. Before professor Shane died, he convinced the pastor to blow up the Council. Next, he had you kill your hybrids, and now he only needs one more massacre, so if he's here, that's what he's doing. We need to find him."

Rosa shrugged. "Or don't."

—

Stefan, Caroline, Rosa and Klaus walk into Shane's office and start looking through his stuff. Well Rosa didn't. She just walked around the room, thinking about how to make them stop trying to stop Silas.

"What are we even looking for?" Caroline asked.

Stefan talked without looking at the rest of them. "Well, if Shane really was working with Silas, chances are he was helping him plan his next move."

Caroline looked at Rosa, "Where, on his evil to-do list? 'Steal blood, perform three massacres, pick up dry cleaning'?" She saw that Rosa wasn't even paying attention. Instead she was just staring off into space.

"Actually, not to nit-pick, but we evil villains usually use minions to pick up our dry cleaning, that sort of thing." He looked over to Rosa smiling, hoping he hand out a smile on her face, but instead she was still staring off into space.

Klaus slowly walked over to Rosa. He heard Caroline say something to Stefan about him, but it wasn't much concern.

He stepped next to Rosa, placing his hand on the small of her back and whispering in her ear, "What's the matter?"

Rosa turned to him, "Nothing." She mumbled.

Klaus looked at her for a moment, not believing her before turning back to Stefan and Caroline and joining into the conversation as if he hadn't left. "Besides, Stefan and I work well together, or at least we did in the twenties."

"Well, granted my emotions were off."

Klaus smirked, "And that's why you were more fun, just as Damon is probably relishing in Elena's emotionless company in New York."

Rosa looked up at Klaus, "What?" She then turned to Stefan. "You let Damon take her to New York?" Back to Klaus. "You knew that he let Damon take her to New York?"

Stefan stepped towards Rosa, but she stepped back. "My brother knows what he's doing."

"Oh I'm sure he does." Rosa said, angrily. "Just like he knew what he was doing when he took advantage of the sure bond and had Elena sleep with him, or I don't know, maybe how he practically forced her to turn off her emotions. Yes, I'm sure Damon has everything perfectly under control."

Everyone stared at Rosa for a minute until Caroline interrupted. "I—I think I found something." She said while carrying a large book over to a desk. "Symbolic Figures in the Dark Arts. Didn't Bonnie talk about expression triangles? Here." She points at a large drawing of a triangle.

Rosa walks closer, making sure to get a good look while Stefan starts to read the page. "In some schools of magic such as Expression, human sacrifice can be used as a focus for power. It is rumored that the addition of two supernatural sacrifices compounds the mystical energy, creating an expression triangle."

Caroline then pointed to another symbol on the drawing, "Humans—that was the council fire." She then pointed at another symbol, "Demons, Klaus' hybrid failure."

"Well, I wouldn't exactly call it a failure. What's the third?"

Caroline suddenly clasped her hands over her mouth. Rosa watched intently. "Oh, no." She whispered.

—

Rosa continued to stare at the book, not paying attention as Stefan, Caroline and Klaus were talking. She didn't even look up until she realized Stefan was gone.

Caroline comes next to Rosa and pulls out a rule and starts drawing lines on the map. "There've been two massacres. Pastor Young's farm is here, and the old Lockwood cellar, where you spitefully slaughtered 12 of your own hybrids is here." Caroline drew another line connecting the two locations. "According to the book, the Expression Triangle is equilateral, putting it here." Caroline drew another two lines, making a triangle.

Rosa studied the triangle, confused. "Somebody's been skipping their geometry classes." Klaus says as he walks up behind the girls. "There are actually two places where the third massacre could be." Klaus draws two more lines making another triangle connected on the map.

Rosa's mouth was slightly parted as she stared at the triangles on the map. Caroline smiled, "Well, you didn't let me finish."

Klaus smiled as he watched Rosa staring at the map confused. "Why so suddenly interested?" He asked.

"I'm just...curious."

Klaus was about to protest when Stefan walked back into the room. "Hey. What's going on? Did you find Bonnie?" Caroline started to bombard Stefan with questions.

"No, but I talked to her dad. I think I found Silas."

—

Rosa, Klaus and Caroline walked through the woods. Klaus had his phone out. Caroline looked over Klaus's shoulder.

"I just want to see where we are." She told him.

Rosa walked next to Klaus, her eyes roaming the forest. "You know, when we split up you did have the option of going with Stefan."

"Yeah? And leave Bonnie's life in your hands? Fat chance. Do you even know how to read a map?"

Klaus placed his hand on Rosa's arm and smiled. "Rosalina's here too, isn't forget."

Caroline sighed, "She's kind of mad at everyone."

"I wouldn't let Bonnie die." Rosa defended herself before walking ahead of Klaus and Caroline.

Klaus sighed and looked at Caroline annoyed as Rosa continued walking further ahead. "Aren't you supposed to be her best friend?"

"Yes. That's why I'm here with you instead of Stefan. But she won't talk to me. She hasn't talked to me since...well since Jeremy." Suddenly Klaus froze. "What?"

"Jeremy." He muttered quietly.

Klaus watched as Rosa stopped walking. "Hey, Klaus? Isn't this supposed to be where it is?"

Klaus walked up to Rosa and saw emptiness. "We're here, although judging by the lack of witches, here is not the correct location."

The corners of Rosa's lips were trying to pull upwards, but she looked down hoping that Klaus wouldn't see.

—

They stood watching the witches in circle. "They're linked. Bonnie's gonna kill them." Stefan told them.

"Not if the witches kill her first." Klaus said before slamming Stefan against a tree.

Rosa gasped and Carolin started to shout. ""Klaus, we need to save her."

"How? The only way to stop the witches is to kill them, and then Silas gets what he wants."

Rosa walked slowly towards the witches. "Spirits, take her soul. Free her from darkness." The person who Rosa assumed was the leader said.

Rosa continued to walk further when Klaus left Stefan and pushed Rosa against a separate tree. "What are you doing?" She shouted at him.

"Not letting you make such a grave mistake." He answered.

Rosa's eyes stared at Klaus's for a moment before they started to drift to what was going on behind him.

Klaus looked at the witches to see Caroline vamp speeding into the circle and shoves a dagger into the leader of the witches chest.

"No!" Klaus shouts as all of the witches in the circle drop dead.

Caroline looks shocked, but quickly regains herself and runs up to her friend. "Bonnie. Bonnie!"

Rosa gasped as Bonnie's eyes opened to nothing but white. She smiled, "The Triangle is complete"

—

Rosa and Caroline sat down in two large rocks, watching as Klaus finished piling dirt over the hole.

"There. Twelve graves for twelve witches. Like it never happened." He rolls down his sleeves and looks at Caroline, "Only it did happen, and now Silas has everything he needs to open the gates to hell on earth." He wouldn't even look at Rosa.

"You were just gonna let Bonnie die." Caroline mumbled.

Klaus sighed. "I know arithmetic isn't either of your strong points, but one is still less than twelve." Klaus told them.

"Yeah, but that one is my friend." Caroline replied.

"You tell yourself whatever you need to do you can sleep at night."

Caroline looked down, "I just killed twelve people."

Klaus shrugs. Caroline looked at him before turning around and leaving. I'm

Rosa stood up, crossing her arms over her body. Klaus shook his head. "You lied to me all day, and I let you."

Rosa looked up at him, frowning slightly."I didn't lie. I just..."

"Didn't tell me you were planning on letting all those people die in order to help Silas bring back every single supernatural creature in the after life."

Rosa raised her voice, "To bring my brother back! To bring your brother back!" She yelled. "Don't you care?"

"Of course I care, Rosalina. Believe me, I want you to have your brother back. I want you to be happy. But you don't understand the consequences of whats about to happen."

Rosa nodded. "I know. And I'm sorry. It's my fault."

"It's not your fault."

Rosa shook her head, "If you hadn't tried to stop me, Caroline never would have gotten the chance to save her."

"Rosalina, don't blame yourself. Just...listen to me next time." Rosa nodded. They turned around and saw someone Rosa hadn't seen before.

"Thank you. Of the three massacres, this is the one I've been dreading."

Klaus smiled, "Silas, I presume."
