A/N - I have been doing a rewatch of Smallville for a while now. And when I got to the episode "Luthor" I suddenly was sparked with idea for a Stefan/Bonnie story. Anyway in that episode Clark was transported to alternate universe and we got to see how one change could alter an entire world. I thought that would be an interesting thing to explore, so I began writing it out.

In my story there are two different worlds, Earth I and Earth II. Earth I is the most similar to canon so for the most part Stefan and Bonnie aren't all that close.

Earth II is quite different from canon. In this world, while Stefan did come to Mystic Falls for the same reason as the show, he actually meets Bonnie that day and is immediately attracted to her. So she ends up being the reason he decides to stay in Mystic Falls. This of course would alter a lot of situations that happened on the show, making both worlds different in many ways.


Salvatore Boardinghouse ─ Earth I

The last thing Stefan wants to do is celebrate his birthday, but he knows if he doesn't he'll have to have to sit through another intervention. Ever since he's gotten out of that safe, everyone has been trying to get him back to normal. It hasn't been all that successful and he knows they are on the cusp of planning another intervention for him, which is not something he wants to deal with at the moment.

So when Elena makes the suggestion to throw him a birthday party, he reluctantly agrees. She managed to get most of the gang to come; even Bonnie who he knows has every reason to not want to attend. She's the only one who hasn't been trying to get him to snap back and knows that it's partially because she's dealing with her own baggage as the anchor.

It makes them similar in many ways. They both were missing for months without any of the others knowing and now that they are both are trying to adjust to being back. He wishes he could talk to her about it, help ease the burden he knows she's carrying, but after everything that's happening between them, he is unsure how to approach her. And he has to admit a part of him wonders if she would even be receptive to him at this point.

He is drawn out of his thoughts when he hears Damon's laughter. It figures that his brother is having more fun at this birthday party than he is.

"So are you having fun?" Elena smiles hopefully at him.

No. Is what he would love to say, but he knows that wouldn't go over very well with anyone in the room. And he doesn't really want to hurt their feelings. He's saved from answering when Caroline and Matt both suggest that he open his gifts. The others agree and soon they are all crowded around a table that has several gifts stacked on top of it.

He smiles weakly and picks up a box. There's no card on the outside, but he figures that whoever gave it will admit to it soon enough. He hastily rips the paper off and opens the cardboard box the gift is stored in. He is surprised to find silver rectangular box with intricate designs on it. He's is so focused on the gift, he doesn't see the looks of surprise from the others at the strange gift.

Intrigued, he twists the box open and is immediately surrounded by blue light. He closes his eyes as the light grows brighter and he feels nauseous all of sudden.

Damon starts to rush over to him, but the light disappears just as quickly as it appeared. He relaxes when he sees Stefan standing there, his eyes shut, but with still intact. Damon doesn't know what was with that gift, but he's glad there wasn't any permanent damage.


Salvatore Boardinghouse ─ Earth II

Stefan almost comes right then and there when he looks down and sees Bonnie's head moving up and down on his shaft. In all his years, he has never seen anything more arousing. When he meets her gaze, her green orbs flash with smugness and he is unable to stop the obscenities from spilling from his mouth.

Bonnie feels warmth flow through her body, feeling both sexy and powerful. Who would have thought, she of all people would have Stefan Salvatore gripping at the bed sheets and shouting out nonsensical words and obscenities.

His eyes close tightly as she continues her assault and eventually his legs begin to quiver. His cock jerks and he knows that he won't last for much longer. And when Bonnie chuckles, the sound vibrating around his length, he comes with a prolonged and loud bellow.

Afterwards, Stefan flops back onto the bed, panting the same way he would if he were fighting an army of vampires. He blinks up at the ceiling as he attempts to come back to himself, his body spasms occasionally from the aftershock of what has to be the best orgasm he's ever had. The only thought running through his mind is that this is a great start to his birthday.

When he finally has control of his motor functions, he feels around on the bed for Bonnie, only to come up with air. Frowning, he sits up and looks around the room for her and is surprised to see her typing something into her phone across the room, in only her lacy underwear. He jumps out of the bed and saunters over to her and starts to suck on her earlobe.

"Come back to bed." He whispers seductively into her ear.

"Mmm," She moans as his mouth moves to her neck. "I have to go."

"You don't really want to go…" He cups her breasts in his hands and squeezes "…do you? If you stay I can make it worth your while." He slides his hands to her hips and grinds his groin into her ass. He grins when she gasps at his move.

She turns around in his arms and smiles apologetically. "I wish I could but I have to meet a client." She frowns as she remembers the client that hired her to help a spirit move on to the other side. Based on what she's heard about the spirit it shouldn't take long and they are paying her quite a bit of money to help them.

"You're really going to leave me alone on my birthday to help a client?" Stefan pretends to be wounded.

"Yep." She shrugs unapologetically. "I have to make a living some way and unlike certain undead people I don't have the ability to compel people into giving me the things I need." She trails her index finger down his chest. "Besides I'll only be gone for a couple of hours. That will leave plenty of time for us to be alone before we have to meet the gang for paintball later."

"I only need ten minutes." His hand dips into the waistband of her panties. "At least right now."

Bonnie sucks in a breath and she knows Stefan can tell she's wavering. He proves this when he slips two of his fingers into her folds, coating them with her arousal. "Stefan, you're not making this easy for me." She groans when he sticks those same fingers into his mouth and sucks them clean.

"If I make it easy for you, I won't get what I want." He retorts before seizing her lips in a searing kiss.

"I'll be more than─ happy to give you ─what you want ─when I come back." She manages to say between kisses. As the kiss continues she quickly realizes they've somehow managed to make it closer to the bed.

She pulls away from the kiss before looking up at him. And immediately realizes what a mistake that is. The look on his face is playful and she knows he is up to something. He takes a long look at his crotch, lingering for several seconds before meeting her gaze and looking down again. When she follows his gaze downward and realizes he's gripping his cock, desire takes over.

Bonnie pushes Stefan against the wall and covers his mouth with hers. Stefan immediately opens his mouth to her, caressing her tongue with his own. His hands skillfully remove her bra and panties before lifting her off the floor and reversing their positions so she's the one pressed against the wall. He smiles slyly at her as quickly he thrusts inside of her, groaning when she wraps her legs and arms more tightly around him.

They move together hurriedly, moans and sighs spilling out as he pounds her against the wall. He is relieved no one else lives in the boardinghouse because they would easily figure out what was happening.

"Told you I could make it worth your while." He says against her lips as he moves in and out of her.

-X-

"Okay now I really do have to go or I'm going to be late." Bonnie says breathlessly from Stefan's chest. What was supposed to be only last ten minutes turned into nearly thirty and now she will have to rush if she wants to make it to her client in time. "I knew I shouldn't have let you talk me into this. It's never only ten minutes with you." She rolls off his chest and starts to climb out of bed.

"But, you're relaxed aren't you?" Stefan sits up slightly, leaning over to press a kiss to Bonnie's calf before she completely makes it out of the bed. He rests his head on one of his arms, watching as Bonnie once again slips on her underwear before opening the closet and pulling out a dress to wear.

"Yeah I am," She slips the dress on, picks up her phone and grimoire and walks over to the bed. "Thank you for that." She leans down to kiss him. "I'll be back soon." She pulls away and smiles at him before rushing out of the room.

The moment she's gone he flops back down on the bed, a relaxed grin on his face. He might as well get some rest before Bonnie gets back. Within minutes, Stefan is asleep, a content smile on his face.

Two Hours later, Stefan is drawn out of his sleep when a bright blue light floods the room. He makes an attempt to get out of bed only feel a searing pain throughout his body. He closes his eyes tightly as he is hit with nausea and dizziness, hoping that they both will eventually pass.

After what seems like forever, the nausea and dizziness goes away along with the bright light, allowing Stefan to feel comfort enough to open his eyes.

However when he opens them is surprised by what he sees.


Earth I

"Stefan, are you okay?" He hears Caroline's voice calling his name.

Stefan opens his eyes and immediately looks around in confusion when he realizes he is no longer in his bed. Instead he is in the living room in the midst of what appears to be a birthday party. Which is strange because Bonnie and the others know he's not a fan of birthday parties. That had been why they decided on going paintballing instead.

He looks to his right and is surprised to his brother. What's Damon doing here? He hasn't seen him since he ran off to chase after Katherine a year and half ago. So why is he here in the boardinghouse as though it's a normal occurrence? His gaze moves from Elena, to Caroline, to Matt before searching for the person that means the most to him.

Bonnie. If anyone can make this situation better, it's her.

The moment his eyes find her he realizes that there's something different about her. It's not just her physical appearance, though that appears to have changed somewhat as well. She's still just as beautiful, but her hair is shorter than it was when he last saw her. Still her physical appearance is only the minor change he sees in her. He's also getting something different from her emotionally. Since the first day they met, he's been to pick up on her emotions. Whether, it's fear, anger, lust, sadness, he has always been able to figure it out without her having to tell him. Apparently today is no different because right now her aura is screaming at him and it's telling him she's upset. About what he has no idea, but he does know whatever it is a big deal.

He frowns when Elena's younger brother wraps his arm around her in a way that indicates they are more than friends. And if he hadn't figured it out before, he knows for sure that he's no longer in his world. He has to be, the alternative is just not a possibility.

"Where the hell am I? I don't belong here." Stefan blurts out suddenly, startling everyone else in the room.

"Great! Just we need a repeat of amnesiac, Stefan" Damon says sarcastically as the others groan, remembering what happened not so long ago. "I knew I should have stopped you from opening that box."

"I never said I had amnesia. I know who all of you are, what I don't know is how I went from lying in my bed to standing in front of all you. And what box are you talking about?"

"The box that you just opened a few minutes ago." Damon explains to him irritated that he has to fix yet another problem around here. "The one that engulfed you in bright blue light a few minutes ago.

"I never opened a box." His brow furrows.

"Stefan, if this is a joke it isn't very funny." Elena frowns at him.

"I'm not trying to be funny." He looks around the room. "I'm telling you this…" He gestures towards them. "… isn't my world. This has to be some kind of alternate world or something." He can only assume some kind of spell went awry or something similar. "It's the only thing that makes sense."

"Why do you think that?" Caroline jumps into the conversation.

"Well for starters, I hate birthday parties and everyone close to me knows that. So they would never throw me a party like this." He says as he looks around the room and glances at the cake and decorations. "Maybe the Stefan you know is different, but I would never go for this. And because things here are too different for them not to be." He says thinking of Damon's presence and the fact that Bonnie seems to be with Jeremy.

"If what you're saying is true, you've only been here all of two minutes." Damon narrows his eyes at Stefan. "How could you already know that things are different from the world you belief you're from?"

"Trust me things are different." He frowns sadly as he looks at Bonnie again, this time meeting her gaze head on. "Way too different."

Bonnie looks away after a few seconds, feeling slightly uncomfortable by the look in his eyes. In all the time that she's known him he's never looked at her like that. Unsure what to think, she fixes her gaze on something the rest of his body.

"Alternate universes?" Jeremy scoffs from his place next to Bonnie. "That's crazy even for us."

"Guys, I think he's telling the truth. Look at his forearm." She points to the distinctive scar on Stefan's arm. She remembers seeing a while ago in Emily's grimoire when they were on they were trying to kill Klaus. If Stefan has the mark then that means... "Klaus is dead in your world isn't he?" She looks up at Stefan, the wheels turning in her head.

"Yeah." Stefan nods.

The all stare at the mark in interest, slowly coming to the conclusion that he's telling the truth. That and the fact that Klaus is alive and well in their world. Which leaves them wondering where their Stefan is.


Earth II

Stefan opens his eyes he realizes that there is something very off about this situation. Instead of being in front of the others in the living room, he's in his bed naked. He sniffs the air and is surprised to smell remnants of sex in the air. He sits up, completely confused especially since the last time he sex had been with Rebekah and that had been months ago.

Startled, he quickly climbs out of bed and rushes to the closet to find some clothes. He's surprised when he realizes that half the closet is filled with women's clothing and shoes. Ignoring that for now, he's pulls out some clothes to wear. Once he's dressed, he looks around the room and spots many other items that indicate a woman is sharing the room with him. His first thought is Elena, but once he looks at the clothing, he realizes the clothes aren't really her style.

His attention goes to one of the large dressers when he sees several picture frames covering the top of it. The first picture is of himself with Tyler and Matt, another features Bonnie, Caroline and Elena in what looks to be their cheerleading uniforms. The first couple of pictures throw him off mostly because he's only keeps pictures with Elena for the most part and he's never taken pictures with Matt or Tyler.

However it's rest of the pictures─ all of himself with Bonnie, that give him the most pause. One picture is of him and Bonnie, his arm extended, making it clear he took the picture. They both have smiles on their faces and her forehead is resting against his cheek. Another picture shows him carrying her on his back and it appears to have been taken at the beach based on their beach attire. The next picture is of him sitting in some kind of chair with Bonnie cradled in his lap; both have smiles on their faces.

Still it's the final picture that captures his attention the most. He and Bonnie are outside some kind of carnival based on the scene in the background. Bonnie is looking into the camera, but his attention is on her. It's not all that different from the other three pictures, but the way he's looking at Bonnie in the picture pulls him in. It's like she is the only person in the world and he's completely and utterly content. It's hard for him to believe because he's never been content, but the guy in that picture seems to be. That's when it hits him that he's definitely not where he's supposed to be. Which leaves him with one question.

Where the hell is he?

He is broken out of his thoughts when the door suddenly opens.

"Bonnie?" He gasps in surprise when he sees Bonnie Bennett looking at him in a way she never has before. Usually when Bonnie looks at him, he sees pain, distrust, and even fear at times, but now when he looks into her eyes he sees love and warmth there.

"Hey, I figured you would still be in bed when I got back." She smiles at him as she makes her way over to him and wraps her arms around his neck.

"I─" He tries to protest, but before he can say anymore her she's pulling him into a kiss. The moment their lips meet he unable to resist returning the kiss, surprised by how amazing her lips feel.

Initially Bonnie matches him kiss for kiss, but it isn't long before it registers that something is different about this kiss. She pushes him away and tries to figure out what's off. Initially everything seems the same; his face, his body, even the way he smells, but she can still tell there is something different about him.

Her gaze moves to his eyes and her heart sinks when she sees something different in his eyes. His eyes look lost and the love she normally sees there is missing. "You're not Stefan are you?" She frowns at him before amending her statement. "At least not my Stefan." She asks with a mixture of worry and sadness in her voice.

"No, I'm not."
