Chapter 4:

Sienna stared at her reflection in the mirror; her top was lifted up so that she could have a full view of her stomach and she turned sideways so that she could see her stomachs profile. She didn't know if it was the result of paranoia, or if it was due to the recent news she had received from Dr. Ryles that she was in fact carrying twins, but Sienna noticed her stomach was swelling.

She had a freaking obvious bump!

Sienna groaned to herself; what she had told Caroline and Luna the other day was true – she didn't care what people thought of her being pregnant and she wasn't going to be ashamed, but that didn't mean she wasn't perceptible to other people's thoughts and the rude words and name-calling they were to throw her way.

Teenage mother at 17, how atrociously despicable.

She didn't even have Stone to protect her or her honor, since he had all but left, shunning her in front of his friends and sticking his tongue down the throats of many girls since dumping her. If Stone … Stone! The love of her life, her first ever boyfriend and the boy she lost her virginity to, the boy she stayed faithful to, believed and accused her of cheating on him and carrying some other guy's child, then the population of Mystic Falls would think no better of her.

There was a heritage display in the Founder's party tomorrow, and Sienna was obligated to go, with her being the daughter of a founder's family and all.

The good news; River, Luna and Caroline would be going with her and she wouldn't be alone. The bad news; she had an obvious bump that didn't look like binge-eating fat, but an actual baby bump. She would need to get a larger size dress, thankfully not from the maternity section yet, but everyone would still notice.

The other bad news; she had promised Damon the other day that she would have him escort her. She was so mad at him for killing Mr. Tanner that she didn't want to be around him or even look at his smug-filled face where that damn permanent smirk never failed to make an appearance. However, she would never regret her decision, otherwise it would be a compelled Caroline going along as his date, and she couldn't have that.

Suddenly, Sienna heard a disturbing groan coming from Stefan's room, and she ran over quickly as possible to check on him. Sienna froze in her place with her mouth held agape when she witnessed the scene she had walked in on; Damon was pulling a knife out of his stomach making a disgusting squelching sound that had her close to barf her insides out.

"What the hell is going on?" demanded Sienna, walking into the room and sitting beside Stefan who looked worried at her being in close contact to Damon with a knife in his hand.

"Nothing Sienna, just Damon messing with my head," Stefan stated with angry eyes fixed on amused electric blue ones.

"All right, I deserved that. But I just wanted to let you know, they caught the culprit," Damon made an extravagant gasp of surprise, "The animal responsible for killing coach Tanner and all those people."

"Funny," scoffed Sienna glaring at Damon, "You're not behind bars or having a stake through your heart – if you even have one," she added bitterly.

Damon smirked at her – Arghh, again with the damn smirks! "Come now Sienna, don't be mean. It was actually a mountain lion. Really big one," he widened his hands showing how big the lion was, "It attacked a hunter this morning. It's all over the news. 'Deadly beast captured. All's well in Mystic Falls.'" Damon made a big performance of quoting the headlines and Sienna couldn't help but roll her eyes.

"Why would you cover your tracks?" asked Stefan suspiciously.

"Wouldn't you like to know," Damon smirked. Sienna growled; she was so not in the mood for Damon's cryptic attitude, "Answer the damn question, Damon!"

"Fine," Damon pointedly smiled at the heavily scowling Sienna, "I've decided to stay a while. And I'm just having way too much fun here with you and Elena, and you of course oh wonderful niece of mine."

"Can't touch her now," said a smug Stefan

Elena, Elena, Elena, doesn't he think of anyone else besides that grating whining bitch?

"Well, the vervain keeps me out of her head. Maybe that's not my target. Believe it or not, Stefan, some girls don't need my persuasion, ask Sienna's bubbly friend Caroline," Damon smirked and Sienna growled at him, and went to lunge at him if it weren't for Stefan's fast reflexes, holding her around the waist. "Some girls just can't resist my charm and my unflinching ability to listen to Taylor Swift."

"You can't get into her house anyways!" said Stefan grasping for straws.

"Really?" said an amused Damon, his eyes flittering to an enraged Sienna. "Because yesterday I stopped by the Gilberts while you were off playing high school student and had a decent chat with the enticing Jenna Sommers about how worried I am about her niece breaking my poor brother's heart. You can thank your niece for the idea."

"What?" Stefan gasped staring wide-eyed at an annoyed Sienna. Unfortunately for Stefan, his attention was on Sienna that he didn't notice Damon lunge at him with the very knife he was recently stabbed with, stabbing him in the stomach.

"Stefan!" screamed Sienna as Stefan fell down on the floor, grunting in pain.

"This is John Vervatos, dude. Dick move," Damon grinned walking out of the room.

Stefan grabbed the knife and threw it on the floor as Sienna fumbled over him in worriment. "What did Damon mean about it being your idea?"

Sienna rolled her eyes; of course Stefan would care more about Elena than the fact he was just stabbed by his brother which hurt him more since he only drank from animals, "Seriously, that's what you care about?" Stefan gave her a deadpanned, serious look and she sighed.

"Fine, I admit, he wanted an invite into Elena's house and I gave him an idea of how to do it."

"But why?" growled Stefan angrily, "Why would you help him?"

Sienna fixed Stefan with a piercing stare, "It was either Elena or Caroline, Stefan. He wanted to use Caroline as his puppet, compel her to be his fake girlfriend so he could get invited into the Gilbert's house. I chose Caroline over Elena, and I will always choose my friends over Elena," Sienna gave him a sympathetic look as she was leaving his room. "I really am sorry Stefan, but I don't give two shits about poor Elena, and if I have to help Damon again to keep my friends safe from him, I'd give up Elena in a heartbeat."

And with that Sienna left the room and headed down to the kitchen where a smug Damon sat drinking a tumbler of his favorite scotch, obviously having heard the whole thing. "Nice speech. How very dramatic of you."

"Shut it! I wasn't going for dramatic. I meant what I said … and the same goes for you too! If I have to put you down to protect my friends, my sisters, then I will. You may be family, but so are River, Luna and Caroline. If you want to be family to me then act like it. Without threats and without killings."

"Oh come on! Tanner was a douche from what I heard. Nobody will miss him!" exclaimed Damon.

Sienna gaped at the vampire, "And that makes it okay?! He had a life, he had a beating heart, and he was human. Just because someone is an ass, that doesn't mean they deserve to die. Who are you to place judgment on what he does and doesn't deserve?!" Sienna growled. "No one deserves to die Damon."

"I'm a vampire, Sienna," Damon shouted flashing over to her face. "It's what I do! I kill, I'm a killer!"

"And I get that. I do. I mean most animals are herbivores while some are carnivore. Humans are carnivores. Vampires are cannibals. I get it; but you could choose to drink from humans and then heal them or leave them with sufficient amount of blood in their system and compel them to forget. Or, you could drink out of blood bags. You don't have to end every human life for a snack," rebutted Sienna, leaving the room and Damon to his thoughts.

His niece really did have a way with words, and he found himself liking her spunky attitude and large repertoire of words and snappy comebacks.

"Knock, knock."

Zach looked up and smiled at his niece as she entered his office and sat on the armchair in front of him, "Sienna, I'm sorry I wasn't around yesterday when you got back from the hospital. How did it go? Are you and the baby all right?"

"Yup, actually," Sienna laughed nervously, twirling a strand of dark hair around her finger, an obvious sign that showed she was nervous, "I'm having twins actually."

"What? Twins!" Zach gaped at his niece, his eyes drifting down to her small baby bump.

"Yeah, well twins and triplets run in my genes, so…" Sienna trailed off nervously.

Zach cleared his throat nervously, "Do you, uh, eh, do you want me to call your parents?"

"No! Not at all. I don't want to bother them with this, let's just … let's just keep this between us for now, kay?" Sienna pleaded him, her olive green eyes beseechingly staring into his hazel ones.

Zach sighed and nodded, "It's up to you Sienna. But the number is in my drawer if you ever need to call them."

Sienna stood up and gave her Uncle Zach a tentative smile, "Okay, got it. Thanks Uncle Zach. I don't know what I would do without you." She gave him a hug and a kiss before running out of his office, leaving an awkward, blushing Zach behind.

Her Uncle Zach was always so awkward; she blamed it on Damon and Stefan. Unlike his twin brother, her father Giuseppe Salvatore, Uncle Zach never bothered trying to have his own family since he was scared of the vampires constantly visiting the Boarding house. Uncle Zach feared having a loving and breathing family, terrified that they would die from Damon's hands like all his ancestors before him did.

"Where are you going Riv?" Stone Fell asked his sister upon seeing her grab her car keys from the hook above the door.

River glanced back and rolled her eyes; Stone always insisted on doing the big brother routine since their parents were always absentee and never bothered asking where they went off to. "I'm picking Sienna up and meeting the girls at the Grill."

"Doesn't she have her own car," Stone sneered rummaging around for a mug so he could pour himself his morning coffee as he had woken up late.

"She does, but the girls and I decided it was better for S not to drive in her recent condition," said River absently. She knew her brother would ask, and she wanted to inform him he was going to be a father to twins; she wouldn't give up hope for her brother to act like he used to before with her best friend and finally take responsibility over the babies he had fathered.

Stone froze, his hand halfway reaching out to the coffee-maker, identical navy blue eyes locked on each other, "Recent condition?"

"Yup," River popped her 'p', "The doctor told her to take it easy now that she is giving birth to twins."

Stone dropped the mug. It crashed on the floor, shards of glass splattering everywhere, but Stone never took his eyes off his sister's, "Twins?"

"Uh-huh," River smirked inwardly, mentally pumping her fist in the air, "Luna went with her yesterday for an ultrasound. Turns out she's pregnant with twins. Anyways I gotta go. Toodles!"

And with that River bounced over to her car to pick up Sienna, cackling with delight. Her poor brother on the other hand, dropped down in a chair with his hands buried in his palms; trying to process the news his dear sister had just imparted him with.

When River and Sienna entered the grill, they found Caroline speaking in hushed tones with Bonnie and Luna sitting on a farther table nursing a cup of coffee.

"You are so lucky you can drink that! I miss caffeine," grumbled Sienna, staring longingly and the murky brown liquid swirling in Luna's mug.

"Ah, ah, ah. No coffee for you," chastised River.

"Yeah, think about it. In about four to five months you'll be able to get hyped up on caffeine again," Luna raised her hands in the air in faux-cheer.

"Actually, that's not true. It's not good for the baby to breast-feed from mommy if she has caffeine in her system … so more than five months," corrected River with a smirk, making Sienna groan as she glared at her two smirking friends, "You two are evil!"

"You know you love us," teased Luna. "By the way, any dates to the founder's party tomorrow? I'm going solo."

"Same here," said River in fake-cheer.

"Damon's taking me," Sienna grumbled angrily. "He wanted to escort his cousin since he's new to town."

"Au contraire mis amigas!" squealed Caroline, sitting in the empty space reserved for her next to Luna, "Damon asked me to be his date this morning. Isn't that great!" she bounced in her seat bubbly.

River was surprised at the look of anger and shock written all over Luna and Sienna's face … especially Sienna. Damon was her cousin after all, she should be thrilled … right?

"What?" snarled Luna.

"What the hell Caroline!" yelled Sienna, drawing some attention over to their table. Sienna didn't give a shit though, screw her hormones, she was actually angry, no scratch that … she wasn't angry, she was furious!

"What?" asked Caroline, the picture perfect face of confusion.

"I told you that Damon is on the rebound. He's just going to use you and then dump you!" snapped Sienna.

"Oh, don't be silly," Caroline giggled with amusement, "Silly, silly Sienna." River, Luna and Sienna gaped at Caroline's very … unCaroline-like behavior. Caroline paid no heed to her friend's baffled looks and leaned in closer, "Guess what Damon told me, you would not believe it! Apparently, both Stefan and Damon dated this girl Katherine, but she picked Damon over Stefan, which drove him mad, so he did horrible things to try and break them up. He manipulated Katherine. He filled her head with all these lies until it finally worked and she turned against poor Damon."

"That's not true!" snarled Sienna, "He's lying to you!" Luna and River still sat gaping at their friend's odd behavior and the story she just told.

"Of course it is, silly. Damon loves me. He wouldn't lie to me," Caroline giggled.

"Excuse me … love? He barely knows you to love you," snapped Luna looking at their blonde friend as though she had lost her marbles.

"Did you hit your head on something hard, Care?" asked River tentatively. River always went for the soft approach while Luna did the tough act routine.

"Oh my god! He didn't!" Sienna hissed, her mind whirling with disbelief and anger as she finally comprehended her friend's odd attitude.

"Didn't what?" River looked at Sienna, waiting for an answer, "Sienna?"

Sienna abruptly stood up, throwing money on the table, "I gotta go."

"What? Go where?" asked Luna.

River stood up as well, "I'm your ride, let me drop you."

"I'm not an invalid, River. I need a walk to be alone with my thoughts, I'll be fine and I promise I'll call or text once I'm at home," Sienna didn't even spare her friends with another glance as she stormed out of the grill.

She was going to kill that bastard! Damon fucking Salvatore compelled Caroline so that he could be her date for the Founder's party, and he obviously fed her with those lies about Stefan so that she could tell Bonnie who would in turn blab to Elena, causing problems between her and Stefan. Sienna could care less about Elena, but Damon went after her friend, and that was unacceptable.

She's going to have her revenge. She will show Damon that no one, no one messes with her friends.

"Sienna?" Sienna turned around and gaped at seeing Stone in his car, staring at her. Sienna glared at him and continued walking.

"Hey! Why aren't you with River? You're not supposed to be walking," he yelled out after her, driving his car alongside her.

Sienna scoffed and threw him a nasty look, "You made it perfectly clear that you don't give a shit and that you care even less about my 'bastard children', so fuck off Stone."

Stone winced, but hid it behind a sneer, "Fine! Be an ungrateful bitch. I was going to offer you a ride home, but forget it."

Sienna rolled her eyes, "I don't want or need a ride from you. Why don't you just go and dawdle off to another one of your skanks and leave me alone."

"I will," Stone sneered at her, speeding off in his car and away from her sight. Sienna wiped a few stray tears off her cheek as she continued on her way to the Boarding house. She was a girl on a mission; she had no time to cry over her ex.

"DAMON! DAMON SALVATORE! GET YOUR ASS DOWN HERE RIGHT NOW!" Sienna yelled. Stefan flashed down instead and Sienna glared at him, "You're not Damon. Where is he?"

"What's wrong? What happened?" asked Stefan worriedly. "High blood pressure isn't good for the babies Sienna."

"Well, fuck that," snarled Sienna, throwing her bag onto the sofa. She then looked down at Stefan's hands and frowned when she saw he was wearing leather gloves, before a smirk of comprehension lit up her features, "You're picking out vervain, good."

"Uh, what do you mean?" Stefan looked unsurely at Sienna. He trusted her and cared for her, but after what she told him that morning freaked him out when it came to Elena's safety and he didn't want to risk it.

"Damon fucking Salvatore went back on our agreement. He compelled Caroline to go to the founder's party with him tomorrow and he fed her made up stories about Katherine … oh, heads up just 'cause I love you, she blabbed to Bonnie who will end up blabbing to your precious girlfriend."

"What? That's perfect," growled Stefan.

"Yup! So you, my amigo and I, are going to team up together and bust his lying, traitorous ass six ways to Sunday," Sienna bobbed her head angrily yet perkily since she had a plan for torturing Damon.

Stefan involuntarily found himself staring at Sienna with amusement, crossing his arms, he said, "And, I take it that you have plan?"

"Of course! Well, a better plan than yours, that's for sure," Sienna mused, looking down at his gloved hands and back into his forest green eyes, "You are planning to probably lace his favorite bottle of scotch with vervain , right? … yeah, well, na-uh, he'll be expecting that."

Stefan looked disconcerted at that, "So then, what's your plan?"

"I was already thinking of lacing vervain into my friends morning drink. I thought I had time to get some from the basement but Damon beat me to it and compelled Caroline. I didn't think he would betray me. Tomorrow my friends are getting ready here for the party, so I'll slip vervain in our drinks. Damon is going to probably start drinking from Caroline and tomorrow at the party you keep an eye out for him. The second he drops down, lock him up in the basement. Capish?"

Stefan smirked, "Nice having you onboard teammate."

"Nice working together Cousin," Sienna winked, her and Stefan trading high-fives as they went down to the basement to get working on liquidizing the vervain.

The next day, Luna, River and Caroline came over to the Boarding house as they got dressed for the founder's party.

"So … Sienna, you don't seem angry anymore that Care is going with Damon," said Luna causally when Caroline stepped into the bathroom. River leaned in to listen since they were talking in hushed tones.

Sienna shrugged, "I told Caroline he was bad news. I mean, I love my cousin, but he's a womanizer. I know him. He only loved a girl once, and she's dead. So … Care is stubborn and refuses to listen to me. The only thing I can do is watch out for her from afar."

"I still can't believe she completely disregarded your words from the other day. She sounded like she understood," Luna shook her head in disbelief.

"Damon has his ways. Most girls just take one glance at his eyes and are hooked in," said Sienna; they had no idea how true her words actually were.

"Not me," said River instantly.

"Me either," scoffed Luna.

Sienna beamed at her friends as Caroline got back. "Look at my baby bump! You promise you girls will stay by my side?" Sienna pouted. Luna, River and Caroline rolled their eyes and laughed.

"Of course you doofus," River giggled.

Luna, River and Sienna took River's car to Lockwood manor, while Caroline left with Damon in his car. It made sense to take River's car since Luna won't be dropping them back home since the party was in her house.

Carol Lockwood was so gracious when she saw Sienna and she winked at her small baby bump drawing her into a hug and ceasing all the whispers around her, especially when Mayor Lockwood himself gave her a kiss on the cheek and a fatherly hug. No one would gossip around Sienna anymore with the Lockwood's support of her pregnancy, and Sienna tried not to burst into emotional tears at how grateful she was for them in her life and for their support in front of the whole town.

But even with the Lockwood's support, it didn't stop everyone from staring at her with wide and condescending eyes at her and her baby bump, or from having the gall to move forward and ask her about the father. Luna and River nearly tore into a couple of snooty guests' heads when they would shut up and leave her alone.

Sienna rolled her eyes upon noticing that Stefan and Damon were congregated around Elena with Caroline hanging on Damon's arm. Sienna couldn't wait for her and Stefan's plan to succeed; yeah, Caroline would have to be bitten by Damon, but it was an unnecessary evil to protect her friend.

Damon picked the wrong Salvatore to mess with; just because she was a girl, human and pregnant, it didn't mean she couldn't hold her own and kick his ass.

"River!" the three girls turned to see Logan Fell approaching them with a beaming smile on his face.

"Uncle Logan," squealed River running into his arms and hugging him.

"It's been a while girls," he smirked at Luna and Sienna.

"You were the one that left town," Luna shot back with a smirk of her own; the girls loved Logan Fell, he was like the cool uncle that spoiled them rotten, and unlike his brother and his sister-in-law, who so happened to be Stone and River's parents, he actually cared about them and spent time with them.

"Touché," Logan laughed, his eyes falling down to Sienna's baby bump and he sighed, "So it is true … I presume Stone's the father … am I right?"

Sienna's eyes bulged slightly in surprise, "You don't think I cheated? 'Cause Stone definitely does."

Logan rolled his eyes and hugged Sienna, "Unlike my idiot nephew, I know how much you love him and that you'd never cheat on him. So, I'm going to be a great-uncle huh?"

"Twins," Luna sang.

"Twins? I'm too young to be a great-uncle to two kids," he laughed, "Well, look. I'm going to go. If you need anything River, I'm only a call away. Same goes for you too, girls."

"Bye!" the three girls echoed.

The girls had fun dancing three-way style the whole night, but Sienna made sure to keep a careful eye on Caroline who danced for a while with Stefan leaving Damon and Elena alone … obviously Damon's plan, compelling her to do so, so that he can have a private moment with Elena and feed her with more lies; which she was of course dumb enough to fall for.

Sienna felt more comfortable knowing Luna, River and Caroline were full on vervain now and couldn't help but feel disappointed at their parents; even though they had no actual proof of vampires being in town, Mystic Falls housed many vampires before and any random vampire could make its way into town.

Plus, ever since Damon arrived, there have been many animal attacks littered around town. The parents in the founder's council should have begun lacing vervain in their children's drinks. She knew for a fact that her Uncle Zach was providing the council with vervain every month.

Sienna noticed Elena storm out of the bathroom like a girl on a mission, slapping Damon hard on the face and yelling at him. She then noticed Stefan give her a subtle look, telling her the plan was now on motion before disappearing after Damon who was dragging a panic-stricken Caroline outside.

She waited for a few minutes, just to make sure that they wouldn't walk in on Stefan and Damon, before telling Luna and River that she lost track of Caroline, and the three girls began their search heading out to the Lockwood's yard where they found Elena hugging a hysterical Caroline.

"Caroline!" Luna and River yelled, running forward to their distraught friend and engulfing her in a hug. Elena stood over them looking awkward.

"You can leave now, Gilbert. You're not needed, we can take care of our best friend," snapped Sienna coldly. Luna left Caroline in River's arms and stood by Sienna's side with her arms crossed and leveled Elena with an icy glare.

"Look, sh-she's my friend too," Elena glared at them, stuttering slightly.

"Yeah, right," scoffed Luna.

"She is!" growled Elena adamantly.

"Of course she is. I mean, because you treat her like such a good friend, right?" snapped Sienna sarcastically.

"What's that supposed to mean?" Elena shouted staring at Sienna and Luna with rage-filled eyes.

"Huh, well. How about the time when Stefan came into town … Caroline was interested in him, but of course you batted your doe-like eyes at him and ensnared him. Leaving a rejected Care. Right after you dumped Matt saying that you needed to be on your own for a while!" Luna mocked her.

"Sounds like such a good friend, don't you think so, Lu?" Sienna declared theatrically.

"I-I, but, I did need time, my parent-"Elena stuttered blankly.

"Yeah, because you're the only one in town that experienced something tragic," snapped Luna. "You dumped Matt and immediately moved on to Stefan … the new guy. Your 'friend' was interested in Stefan, yet you held no honor and took him from her."

"The only person you can be a good friend to is Bennett, and I doubt that would last. Don't think we haven't heard you speak about Caroline behind her back," Sienna took a few steps closer to Elena, who backed up slightly, "Let's clear out the air Gilbert. I don't like you and I sure as hell don't trust you. You may have been able to snag my cousin, but I'm watching you. I know your moves and your tricks, and guess what hun? We're not falling for the poor damsel in distress act you so fondly put on. One day, everyone is going to see you for the manipulative bitch you are and you won't have anyone to fall back on."

"Now leave!" snarled Luna. Elena wasted no time in leaving the four girls and scurrying back into the Lockwood manor and the girls helped Caroline into River's car so that she could drop her home.

When Sienna reached the Boarding house, she decided that she would confront Damon in the morning as she had tired herself out a great deal and stressed too much. Her babies needed some well-rested sleep. Sienna went to bed feeling a lot safer now that Damon was locked up in the cell.

Sienna smirked to herself; Yes, Damon, the headline reads 'Deadly beast captured. All is well in Mystic Falls.'

A/N: I enjoyed writing this chapter and the girls. I decided to have Damon compel Caroline at the last second so that we could see Sienna's vengeance and protective side when it comes to her friends, and I wanted a scene where she and Stefan worked together. Damon is now locked in the dungeon; next chapter we will have Sienna confront him. Sienna did warn him not to mess with her friends; he decided to challenge her and he got burnt.

If you guys have any ideas, let me know and I'll see if I can fit it in with my plot.

R&R.
