Thea Salvatore slowed down as she turned into the circular driveway of the Salvatore Boarding house, she hadn't been there in a long time but like Damon's visits, Thea's usually ended with death.

Thea opened the door of the car and climbed out, squinting against the sun, she hated the sun, even as a human Thea had preferred the nighttime.

The spent a few minutes looking around the house, she knew at least one of her brothers where there due to the fact that there had been a few recent deaths with all the signs of a vampire, weather is was Damon or Stefan on one of his ripper trips she didn't know but either one would prove to bring some fun.

Thea walked into the living room and poured herself a glass of Scotch, sipping it as she picked up a few random knickknacks and set them down in different places.

She paused when she heard footsteps and instantly knew it was Zach, Thea turned toward a book shelf and ran her fingers down the spines of the books, waiting for him to notice her and speak.

"I didn't know you were here." Zach said, his voice not hiding his surprise and fear.

"I'm sure there are lots of things you don't know." Thea said in a wickedly sweet voice.

Thea turned to look at Zach who was eyeing her carefully a worried look in his eyes, Thea stopped walking and swirled her drink around. "Go ahead, purge. Get it out. What's on your mind?"

"Why are you here, Thea?" Zach asked, his voice shaking.

""To spend time with you, Zach." Thea said, smiling. "Family is important, don't you think?"

"I know you, you always have a motive." Zach said. "So tell me, what is it this time? Why are you and Damon and Stefan here?"

"You are in no position to question me!" Thea snapped and in a blink of an eye she was in front of Zach, her hand around his neck, her drink in the other hand. Her facial expression had changed drastically, her once bright blue eyes where dark, the veins sticking out around them and her fangs had come out, and they were so long that they almost scrapped the bottom of her lip.

"I didn't mean to upset you." Zach gasped.

"I'm not upset Zach." Thea said, smiling. The smile only proved to make her look even more sinister and Zach's heart skipped a few beats.

"What's going on?" Stefan called from the doorway. "Thea, what are you doing here?"

"Just having a family moment, Stefan. Spending some quality time." Thea said, her face relaxing, the fangs retreating the veins disappearing. "I think I'll go find Damon, see you two later."

Thea walked slowly out of the room and paused just out of view.

"Hey, you okay?" Stefan asked, Zach.

"No, I'm not. And neither are you. How many more people have to die before you see that?" Zach asked, he spoke more freely with Stefan then with either Thea or Damon.

"I see it, all right Zach. I see it." Stefan said.

"Then why aren't you doing anything about it?"

"I can't, Zach." Stefan snapped. "It would take human blood. It's the only way that I could stop them. And I can't do that."

"We have to do something, they're both here."

"I know, Zach." Stefan said, his voice sounded tired and Thea almost felt badly for him. Almost. "They're bad enough apart, but together…Thea isn't like Damon, she is much much worse. We have to do something but how I do I get them both?"

"Vervain would weaken them. If they ingested it, it would help you get the upper hand."

"Vervain hasn't grown here since 1865. Damon saw to that. The little I had, I gave to Elena."

Thea inched away from the wall and hurried upstairs to Damon's room, the door was open and Damon was watching TV, without a word and in a second Thea was on the bed tackling him, at first Damon was truly aggressive but once he noticed it was Thea his movements became more playful, they wrestled on the bed for a few moments until Damon pinned Thea to the floor.

"Hello, sister." Damon said, pulling Thea into a hug. Thea rested her head on Damon's shoulder and in a brief show of emotion let a small tear escape.

"What are you doing here?" Damon asked, pulling away.

"I got wind of some vampire attacks in Mystic Falls, and I thought. Is that my brother? Little did I know that it was both of my brothers?"

"I'm glad you came, Thea, I could use a little help." Damon said.

"Fill me in." Thea said. "I think we both have some useful information."

Thea sat on the bottom of Stefan's bed, flipping through one of his diary absently, she was dressed in a skimpy black dress, eight in-heels and her make-up done beautifully. Damon was rummaging through Stefan's closet.

"Do they still wear ties at this thing?" Damon asked.

"Why are you even going?" Stefan asked.

"It's only fitting. We were at the very first one, remember?"

"I think it's better if we don't draw attention to ourselves." Stefan said.

"So you should stay here." Thea said, as Stefan walked over and grabbed the diary away from Thea.

"I'll see to it Elena has a good time." Damon said, smirking. Stefan grabbed his drink and took a sip. "My goodness, I've driven you to drink."

"Can't seem to rid myself of you, what else am I supposed to do, besides go about living my life?" Stefan asked.

"See, therein lies your eternal draggle, Stef." Thea said. "You're dead dude, get over it."

"It's cool not growin' old." Damon said. "I like being the eternal stud."

"Yes, being a 150-year-old teenager has been the height of my happiness." Stefan said.

"You racked a funny, Steffie. We should have a drink to celebrate." Thea said, grabbing the Scotch and pouring to glasses.

"1864. You and Katherine were the perfect couple." Damon said. "It was hell watching you dance with her."

"My happiness was short-lived, as you well know." Stefan said, tying his shoe.

"I remember, I left the party early, iw as waiting for her. The night you dropped her off, I was waiting just inside. You were such a gentleman, gave her a kiss on the cheek. And what she really wanted was…oh, well. Here's to history repeating itself, huh?" Damon asked as Thea handed him his drink.

Thea and Damon both glanced at each other before dropping there cups onto the floor.

"I admire your effort, Stefan." Thea said, her eyes going dark. "Pouring yourself a drink them spiking the bottle with vervain. I'm not some drunk sorority chick, you can't roofie me." Thea growled, getting angrier. "I can't help but feel a little used. I thought we were having a moment." Thea said, her expression instantly changing into one of placid happiness. "I have to go the party angry, who knows what I'll do."

Thea pushed past Stefan and walked out of the room.

"Any dead bodies are on you tonight, Stefan." Thea hissed over her shoulder.

Thea walked beside Damon, her arm in the crook of his elbow. On the other side of Damon was Caroline Forbes who was eyeing Thea carefully.

"So this is who you're spending your time with?" Thea whispered to Damon.

"She's Elena's best friend." Damon said, shrugging.

"Caroline! You look smashing." A tall brunette woman said.

"Thank you, Mrs. Lockwood. This is my boyfriend Damon and his little sister Thea."

"Oh, well, come on in." Mrs. Lockwood said.

"Lovely to meet you. I've been looking forward to this party for quite a while." Damon said.

"Well, enjoy."

"Sorry about crashing, I hadn't planned on visiting Stefan and Damon, I hope you don't mind." Thea said, her voice sweet and sincere, though she was neither.

"Not at all." Mrs. Lockwood said, smiling.

Once inside, Thea gave Damon a kis son the cheek and hurried away, compelling several different guys to dance with her and drinking glass after glass of champagne, a few hours later she found Damon and Caroline.

Thea guessed the girl was Elena.

"Hey, Damon, will you dance with me?" Thea asked, walking over to them.

"I don't dance Thea." Damon said, smirking.

"Just once, please?" Thea asked, giving him a sad face which they both knew was fake.

"Just one." Damon said, relenting.

"You wouldn't dance with me but you'll dance with her?" Caroline asked, crossing her arms angrily.

"She's my sister Caroline; I'd pick her over you any day." Damon said.

They danced the one song and when they were vanished they walked back over to Caroline, Stefan and Elena.

"What'd we miss?" Damon asked, still holding onto Thea's hand.

"We were just chatting." Caroline said.

"You must be Elena, I'm Thea." Thea said, smiling. "I'm Stefan and Damon's sister."

"Do you have any more secret siblings?" Elena joked.

"No more, I promise." Stefan said.

"Drink, Damon?" Stefan asked as a waiter walked past.

"No, thanks, I'll pass."

"Stefan, do you have another dance in you?" Elena asked.

"Absolutely." Stefan said, grabbing her hand.

"Save one for me, Stef." Thea called softly after them, Stefan nodded briefly but kept walking.

"They look so cute together." Caroline commented.

"Don't talk, please." Damon ordered and Caroline frowned at his comment."

"Come on, Damon. Let's dance again." Thea said.

"No, I gave you one dance that's all." Damon said.

"Fine." Thea said, pretending to put. "I'll find someone else."

Thea danced a little bit longer before finding Stefan.

"Can I have my dance now?" Thea asked.

"Sure." Stefan said, leading her onto the dance floor.

"I remember the first one." Thea said, wistfully. "I was so jealous, Father wouldn't let me go. He said I was to little, that next year I could go. I told him it didn't matter about next year, this was the first one but he didn't care." Thea said and then added mischievously as if she was revealing a big secret. "I didn't listen, I snuck away. I saw everyone, dancing and…I hated you, and I hated Damon, you left me behind and didn't care even a little bit that I was sad or lonely." Thea said, her face was sad and then it changed again, to one of anger. "Why'd you do that? Why'd you not care about me? All you cared about was Katherine and your love for her."

"I'm sorry, Thea. I admit I wasn't a good brother then, I'm sorry."

"That was a long time ago." Thea said, smiling a little. "Why'd you do it? Put the vervain in the drink?"

"It was for Damon." Stefan said, looking away for a second.

"Don't lie to me Stefan, it only makes it worse."

"I don't want people to die here; I want to make a home for myself."

"You could have asked, told me you wanted it safe. I can cover my tracks; I don't have to kill. You didn't even give me a chance."

"I should have trusted you more, Thea, I'm sorry."

"You aren't sorry, but you will be." Thea said, leaning close to Stefan's ear. "This town is going to rain blood, and it will be all your fault."

Thea pulled away, smiling as she bit her lip. She winked at Stefan and danced away.

Thea saw Damon walk out a back door, dragging Caroline behind him, Thea could feel Damon's anger and she giggled in delight hurrying after him.

"Don't!" Caroline begged. "She took it off and I got flustered, okay? I didn't know what to say, but I swear, okay, I did not tell her. I just told her that you didn't meant o hurt me."

"You make me crazy, you know that?" Damon said, kissing her neck. "It's okay, I forgive you."

Thea frowned angrily, she had hoped to see some blood to feel death in the air but instead she was getting this. But in the next moment Damon sank his fangs into her neck, it wasn't the same type that he would give to someone he wanted to live, he was angry and Thea gleefully skipped over to join.

"Unfortunately, I am so over you." Damon whispered.

Damon fell to the floor in pain and before Thea could do or say anything, she felt a sharp prick in her neck and she felt her own pain.

Thea blinked her eyes, everything was heavy and painful and dark.

"What the hell?" Damon gasped beside her.

"I know, I could spike your drink…so I spiked hers, and a simple syringe to the neck for, Thea." Stefan said. "This is for the best.
