Chapter one- One Night That Changes Everything

June 8th, 2010

It was a hot summer day in Mystic Falls, and the sun was shining through the bedroom window, threatening to wake Damon up from his well deserved rest, after all he performed at his highest level last night, he thought while smirking to himself.

"What are you smirking about?" Elena questioned him curiously as she watched him sleep from the seat on the window sill.

Damon's smirk grew even wider with that question. He loved her voice, he loved everything about her, not that he was ever mushy about these things but it was still the truth. He knew she liked to sit on the window seat and watch him sleep. He'd always tease her about it, but he sometimes watched her sleep too.

"I was thinking how amazing last night must have been for you," he replied, opening his eyes now and waggling his eyebrows.

Elena laughed despite herself, "Your ego is so big I don't know how there is any space left in this room. Besides, it was I who was pleasing you last night," she explained grinning at him wickedly as she hopped onto the bed.

"Fine, Fine, we both performed equally well last night," he said with a dramatic sigh.

"Yea well you better keep it up mister or I'll just have to find me a new man" Elena said, looking at her nails, trying to hide a grin, she knew this would drive him crazy.

Damon's mouth hung open in shock just for a second when he realized she was just riling him up as usual. Now it was his turn to have some fun. He got a wicked grin on his face and just stared at her with his sexy, smoldering eyes.

"Why are you looking at me like that? Damon?"

All of a sudden he laid her down and he was straddled on top of her, tickling her mercilessly, causing Elena to emit shrieks of giggles.

"Damon….please….stop…" she said in between laughing and trying to catch her breath.

"Mm, sorry, no can do. Not until you take back your last statement."

Elena had a small smile on her face as she shook her head no and then she started laughing again when he proceeded to tickle her.

"Say it…" Damon said while laughing at her happiness.

"Fine!" Elena yelled and she finally caught her breath as Damon sat on top of her waiting.

"You, Damon Salvatore, are my soul mate and I would never dream of finding another man," she proclaimed to him shyly and he leaned down and kissed her feverishly.

"You're mine too." He said seriously, as she held his hand in hers and pulled him off the bed.

"C'mon, let's get dressed and I'll make us some breakfast."

"Can we do it naked?" Damon asked, completely serious.

"Considering that your brother is going to be here any minute…" Elena mentioned as she pretended to ponder, she started to walk towards their bedroom door, "I mean that's up to you, if you want him to see me naked I guess it would be okay…" She turned around to look at him innocently.

"Run. You'd better run Elena."

Elena looked at him wide eyed as she starting running down the stairs laughing as she heard him close behind. She made it all the way to the kitchen before he had her pinned up against the wall.

"You just think your sooo funny today, don't you Elena." Damon said with the slightest edge to his voice.

"Oh c'mon I was just kidding. Look I'm sorry it was a bad joke," she said placing her hands on his chest and leaning close to his ear, "I promise I could never look at any man the way I look at you," she whispered and she could almost feel the slight grin forming on his lips.

"Good, because you know, if women knew I was single for some reason, they'd be lining up to date me."

Elena pushed him away glaring, and he responded "Hey, you started this."

The door bell rang, and Damon groaned knowing it was Stefan and he was having such a good morning until then.

"I'll get it," Elena exclaimed seeing his reaction, "don't be such a baby, he's your brother."

"Elena my dear, you are not answering the door."

"Why the hell not?"

"Because you are still in your very sexy night gown and Stefan cannot see you like that."

Elena blushed, "Oh right, okay you answer the door and be nice. I love you," She said kissing him on the cheek as she ran upstairs to change.

Damon shook his head, and walked to the door, "Well, hello brother."

"Hey, Damon, where's Elena?" Stefan asked casually.

"You know, some might find it suspicious, and quite frankly rude that your first response to me is always about my girlfriend. Never a 'hey Damon, how's it going' or 'So Damon, I finally admit I'm gay..'"

"And some might call you paranoid. I don't know what Elena sees in you sometimes."

"Well clearly no girl finds you worthwhile," Damon said glaring, wishing he'd never opened the door.

"Hey Stefan!" Elena said cheerily as she walked over and gave him a hug, "Well don't just stand there, come in."

"See Damon, Elena could give you some pointers on greeting techniques," Stefan said with a very small smirk of his own.

"Well clearly I could give you some dating techniques, when was the last time you got laid? Let me think…" Damon said while patting his chin with his index finger, deeply pondering.

"Oh! Silly me, it's been what like a year?"

Stefan was ready to retort back, but Elena stepped in, "Guys, can't you get along for more than a few seconds?" she asked glancing back and forth between their rigid postures.

"Ugh, I swear you both are impossible."

Damon put his arm around her shoulder and pulled her close, kissing her head, "Well as fun as this is, I have some errands to run my dear, so you enjoy your time with not so saintly Stefan, and I will see you later."

Then he pulled her face to his for one more breathtaking kiss, just to prove to Stefan that she was his. When he pulled apart, he chuckled as he saw her stumble a bit.

"And that is how it's done, my dear brother," Damon said smirking, as he patted him on the back and walked out the door.

"Sorry," Elena said to Stefan blushing, "he's just you know, with your history…"

"I know Elena, don't worry, it's actually kind of amusing."

"Thanks…I think? Um, so did you bring it?"

Stefan nodded and handed her the bag.

Damon walked along the streets of the town, glancing in store windows every now and then to see what new items had come in, but he didn't stop in as he liked to do sometimes, no today he had only one store to go to and it was for a very specific reason.

He took a deep breath, when he reached his destination, but he smiled as he walked inside.

"Hi can I help you?" The sales clerk asked him

"Yes, I'm looking for an engagement ring. Something sterling silver, preferably very simple but elegant with sapphire stones on each side of a heart shaped diamond in the middle. I think it should be ready to be picked up now, I talked with Chuck about customizing the ring weeks ago. "

"Okay and your name please?"

"Damon Salvatore.

"Okay, let me go check in the back."

Damon browsed at the other rings while he waited, pleased with himself that none compared to the one he created himself. He really wanted this to be special for Elena.

"I hope you're getting a ring for me…" a girl stated innocently.

Damon turned around, his heart sinking, she couldn't find out like this.

"Elena? What are you doing here? I thought you were hanging with my brother today…"

"Not Elena, you silly boy. It's me. Katherine." She explained with a smirk of her own that rivaled Damon's.

"Ha ha, very funny Elena, you really shouldn't be here right now. You'll ruin the surprise," Damon grumbled.

"Who is this Elena? It's me Damon! The love of your life….Katherine."

"If you're really Katherine, then tell me why I got arrested that one time."

"You got arrested?" Katherine asked, feigning shock

"See I knew you were Elena….and you thought you could fool me," Damon said, waving his finger at her.

"Oh but I did, you were arrested because you almost killed your father because you found out that he had been beating your mother" Katherine replied innocently, giving him an evil smile.

Damon had a deep frown on his face, gritting his teeth he said, "Well, Katherine, you haven't changed bit."

"Oh Damon, that is a compliment of the highest order. Why would I ever want to change when I get everything that I want?"

"Gee I don't know, maybe because you are a bitch!"

"Now, now, I really thought you might have been over me by now," Katherine said sighing dramatically.

"Are you delusional? Of course I'm over you. I'm here buying a ring! For Elena!"

"Fine, fine, come with me to the Mystic Grill then so we can catch up, and you must tell me about this girl who has stolen your heart."

He glared at her, "Why don't you catch up with my brother? In fact, I'm sure he'd love to see you, and just a warning, he's a little out of practice if you know what I mean," Damon said winking at her.

"No! I want to see you, c'mon just to catch up, for old times' sake."

"You have an hour," Damon replied and thanked the sales clerk who had finally come out of the back and he grabbed the ring and stalked out of the store, Katherine following behind him, grinning wickedly, ready to bring her plan into effect.

They walked into the Mystic Grill and took a seat at the bar, Damon immediately ordering a shot of whiskey to calm his nerves, and Katherine did the same, why should he have all the fun.

After two more shots, Damon turned to look at her, a bored expression on his face since Katherine was just staring at him, "Well this has been a riot, let's do it again sometime. But you see there's this girl, Elena, and I really need to be getting back to her."

"Oh right! The mysterious Elena, do tell me about this charming girl," Katherine said sarcastically.

"Gladly. Let's see I met Elena about a year ago, we moved in after 6 months, and have been living together ever since. She's the complete opposite of you—kind, warm, playful, selfless, caring, and I can go on and on but I think you get the hint. She's everything you weren't."

Katherine glared at him, she really hadn't expected this and she knew Damon well enough to know when he was lying and this wasn't one of those times. The anger was building up inside her. This would not do. He was supposed to pine for her until she returned so she could have her way with him like all those years ago. He was supposed to be her toy and then she could go after her real treasure, the real reason she came back—Stefan. There was only one option left, and even though it deviated from her original plan it would have to do.

"My, My, I see I have clearly under estimated this girl. She seems fantastic, I'll simply have to meet her."

"Absolutely not! Meeting you would be poison to her and our relationship. Nothing good happens around you, but that's okay because if it weren't for you, I never would have met Elena."

"Well, see Damon, you owe me for this wonderful relationship you seem to have going."

He scoffed at her as he took another shot, "That'll be the day. So what have you been up to Katherine?"

"Oh me?" she said batting her eyelashes, "I've been traveling mostly, and well as you know there have been quite a few men in between. They just seem to fall at my feet, kind of like you did."

"I was young and naïve then, I wouldn't make that mistake again. I told you, go find Stefan."

Katherine pouted, "You used to adore me Damon, I know you must still feel something for me somewhere, but I get it, you're with Elena now. But don't you remember the fun we used to have, let's play a drinking game and I promise I'll leave you alone."

"One game. That's it."

Katherine ordered a round of shots, mumbling under her breath, "let the games begin."

It was about thirty minutes and 10 shots later, and Damon was starting to feel a buzz.

"My turn to ask!" Katherine said, pretending to be drunk, she could hold her liquor better than anyone, and much to Damon's dislike they were playing one of Katherine's games that made absolutely no sense. Basically, every time you were asked a question you had to drink. There were some things he would never understand, but that was just Katherine, no matter what it was, guys tended to do the things she wanted.

"So where is Elena today?"

"She was hanging out with Stefan today. They're good friends"

"Oh you mean good friends like me and Stefan?" she asked innocently

Damon stopped mid drink, and slammed it down.

"Their friendship, is nothing like yours' and Stefan's! Elena would never do that to me," Damon replied in a harsh tone and Katherine knew she had found the right chord.

"You never thought I would either, but I did. What makes Elena any different?"

"Because unlike you, she actually loves me back. You're the one who was always incapable of love, your heart is like a black hole."

"Thanks, I try. But really, do they do this often and do you always leave them alone together? You must really trust her, after all, it is Stefan we're talking about here."

"We're done here. Have a nice life Katherine." Damon said angrily as he rose from the bar stool.

Katherine stood up and placed her hands on his shoulders looking deeply into his eyes, "You will go home and you will tell Elena that you know she's been sleeping with Stefan. You will tell her she's a whore and any other hurtful things you can think of. She betrayed you, and then when you are done, I want you to come right back here."

"I understand," Damon replied and Katherine kissed him on the cheek as he walked out.

"Good boy," she said to his retreating form.

When Damon arrived home, he was fuming due to Katherine's compulsion and it 10:00; he had been gone for 12 hours. Elena was pacing around the living room. Damon never stayed out this long, at least not without calling her, she wanted to report him missing several times but she knew that was irrational. When she finally heard the door unlocking she looked up and her smile faded when she noticed he was drunk.

"Where the hell have you been? You said you had errands to run and you're gone 12 hourss? I didn't know where you were! You could have been lying in a ditch somewhere!" Elena screamed at him, releasing all her worries and frustration.

"Oh don't act all concerned," He said sneering at her.

"What are you talking about? Of course I'm concerned," Elena said lowering her voice a little, "You never go out that long without calling me or get drunk. What happened?" She asked coming over to give him a hug but he pushed her away.

"What happened? What happened is that I know Elena!" Damon screamed

"You know? But.."

"You don't even deny it! Yes I know that you've been sleeping with my brother behind my back!"

"What are you talking about? Are you insane? Of course I'm not sleeping with your brother." Elena replied started to get really upset, she didn't know what was going on.

"Oh don't act all innocent. You're just like Katherine, sleeping with my brother behind my back. You're nothing but a whore."

Elena walked up to Damon and slapped him across the face. "How dare you," she said in a low, angry voice, "How dare you, walk in here 12 hours later and accuse me of such things? I have never done anything to break your trust, I LOVE you. Please tell me where this is coming from." Elena begged him as tears started falling down her cheeks.

Damon stood there staring at her, facing an inner struggle. A part of him knew that this was all wrong and that he shouldn't be doing this, but a slightly stronger part made him continue, as if he wasn't in control.

"You don't love me. You love Stefan. It will always be Stefan!"He yelled, picking up a glass and throwing it at the wall.

"Stop it! Just stop! I love you, not Stefan. Never Stefan. You need to come back to me Damon."

"I wish I had never met you Elena, go to hell," Damon said glaring at her and heading for the door.

"Damon," Elena yelled in between anguishing sobs, "please don't go, just rest and we'll talk in the morning. I love you, I promise you nothing has happened."

But, he never stopped, nor turned around. He just walked right out the door and Elena fell to her knees and continued to cry.

Not long after, the disastrous fight, Damon found himself in the Mystic Grill, drinking shot after shot. He just wanted to forget this night ever happened. He looked at the clock about an hour later, through his blurry vision, and he put his head down. He was plastered by now and Katherine knew this. She sat down next to him but was careful not to disturb him. She needed him asleep after all. She read a magazine out of sheer boredom to pass the time. Twenty minutes later when she was sure he was finally asleep, she helped him up and led him to the outside alley. She carefully laid him down, and got into position.

"Now don't worry, this won't hurt a bit," she said to a barely conscious Damon and then if you were in that alley you would have saw Katherine bight into her wrist and feed Damon her blood, and then if you listened very closely, you would have hear his neck snap.

The next morning Damon woke up with a pounding headache, and he was squinting his eyes at the sun. He went to rub his eyes with him hand when he felt something cool, touch his skin. He saw that he was wearing a ring, one that he didn't remember getting. Then as she slowly looked around the room, he started to panic, not knowing where he was. He looked down and found that he was only in his boxers and he felt sick. He felt a rush of memories come back to him with such intensity. He remembered fighting with Elena last night and accusing her of awful things and he remembered getting drunk but ten it went blank.

"Finally, You're awake," Katherine said sitting on the bed.

"Katherine what are you doing here? What I am doing here?"

She gasped, "You don't remember? That insults me Damon, we had a beautiful night last night."

"What are you talking about?" He said through gritted teeth.

"I'm talking about us reconnecting, you know having sex," She replied, smiling.

"You're lying. I know I fought with Elena last night, but I wouldn't do that to her."

"Don't worry, it can be our little secret."

"No! This didn't happen, I wouldn't do that, I-I need to go home," Damon said as he walked around the room picking up his clothes.

"Oh but Damon, you can't go home," she replied innocently.

"What are you talking about? Yes things are bad but I'll fix them."

"Well, okay but there's something you should know."

Damon looked at her, waiting for a reponse.

"Aren't you thirsty? Does your tongue feel heavy? Are you craving anything?"

Once she mentioned it, Damon started to feel everything she was talking about and he had an unbearable craving for blood.

"Why am I craving blood?" He asked almost calmly, afraid of the answer, Stefan had mentioned something to him very briefly once but he never paid much attention.

"Because you're a vampire now. Just like me, and now we can spend the rest of eternity together."

Using his newfound strength and speed Damon grabbed Katherine by the neck and slammed her into the wall.

"Mm, aggressive, just like last night," she replied smirking.

"Stop!" he roared, his fangs coming out now, "Why did you do this to me? Why couldn't you just leave me alone."

"Because," she started in a bored tone, "Elena can't have you, I want you."

"Well that's too bad. I'm going back to Elena."

Katherine laughed at him, a dangerous low laugh.

"You fool. You think you can go back to Elena, you're a vampire now! She'll only see you as a monster. She'll want nothing to do with you. Besides that, you're a new born. You could easily kill her, draining her of her blood. You wouldn't want to do that now would you?"

He pressed harder against her throat, "You have taken everything from me and if I didn't need you right now I would kill you. But I swear Katherine, one day I will kill you. You ruined my life." He let go of her and left the room slamming the door.

"He'll be back," Katherine said as she simply shrugged and went to take a shower.

Damon walked to his and Elena's apartment and watched her through the window. She was sleeping on the couch probably waiting for him to come home. He heard her heartbeat and it made him want to drink her blood. That's when he knew Katherine was right, he was a monster and he could harm Elena, he gave her sleeping figure one last longing look and walked away.

Five Years Later- June 8th 2015

Five years. It had been five years ago that he and Katherine had left his town and now they were back. He didn't know how long he had been standing outside their old apartment when he finally walked over to her new house not too far from there. It had been 5 years since he had even seen her, since he heard her voice. He wasn't sure he was ready to see her but he couldn't wait anymore. It felt strange to flip the switch and have his humanity back for a little while. It was the only way he could deal when he left- to shut everything off and to survive with Katherine. But now that he was back, he felt like he deserved some pain, he just didn't know it would be this hard. He was about to leave when he realized he had been caught. Elena stepped out of the house and stopped on her front porch, just staring at him.

"Hello, Elena."
