Sebastian pulls his Porsche into the underground parking garage located a convenient few blocks down from the deli where Barry said to meet him. It also happens to be several blocks away from the Lower Manhattan Police Department. Barry mentioned that the deli he chose is a popular cop hang out.

Sebastian wouldn't know.

But he thought that comment might have been Barry's subtle way of reminding Sebastian to be on his best behavior.

Sebastian smiles. Only a few conversations, and Barry's already got him pegged.

Sebastian was surprised when he got Barry's text. He honestly thought he'd never hear from the man again. When he first read the message without Googling the number it came from, he thought it might be Kurt playing a trick on him, a little bit of roleplay to spice things up, maybe even to apologize more than he already had.

Or a test, which was likely, too, knowing Kurt.

But after Sebastian called back, he discovered that it was indeed Barry Allen. Barry had been intrigued by meeting Sebastian and Kurt, enough that he had spent all that night lying awake, thinking about it, and wondered if he could possibly take Sebastian up on his offer. Or at least discuss it. Sebastian made it very clear that, regardless of how he might have come across, he didn't do a thing without his boyfriend. He and Kurt were a packaged deal. Barry agreed. He said that he had a long time boyfriend of his own, and that he would need to be factored into the equation, or it would be a no go for him as well.

One step at a time. They decided to go for lunch and talk it over, see if they were, in fact, compatible, and then decide on how best to break it to their significant others.

Sebastian knows he can get Kurt on board, no problem. They would just need to convince Barry's boyfriend. Sebastian was praying for a big ole yes. After all, how often do you actually come across your Doppelganger in your lifetime?

For Sebastian, this is an event of comic book proportions. Even if Barry has no intention of doing anything sexual with him and Kurt, it would be interesting to get to know this man, find out what walk of life he comes from, what his childhood was like, where he went to school, what were his dreams, his aspirations, how he ended up working for the police. Looking at Barry, imagining the life he might have led that brought him to this point, is almost like looking at what Sebastian's life could have been if he hadn't been born to privilege; if he hadn't taken those left turns when he could have gone right; if he hadn't met Kurt, hated him, and then fallen in love; unlike Barry, who seems married to his job.

Sebastian checks the time on his phone as he walks out of the garage, then double checks his messages. He's preparing to send a quick text to his boyfriend to make arrangements for dinner when he glances up to see where he's going and, speak of the devil, there he is. Sebastian cocks a brow and chuckles to himself. He guesses even after everything that happened - their long talk, and the remarkable apology sex that followed - Kurt is just too fascinated by Barry to stay away.

"Motherfuckin' Kurt," Sebastian mutters to himself, shaking his head. He's not hurt anymore, and he's not mad. He can see the humor in his boyfriend being obsessed with someone who looks exactly like the man he loves. It could be the plot of an M. Night Shyamalan movie. Now all Sebastian has to do is keep an eye out for the plot twist and hope no one gets murdered … or kidnapped by aliens. With any luck, he and Kurt will both get the chance to fuck this obsession out of their systems, literally, and everything will go back to the way it was B.B.A.

Before Barry Allen.

Sebastian sneaks up behind Kurt, eager to hear the excuse his smitten boyfriend comes up with for showing up here, not knowing that Sebastian would be there, too. Sebastian's beginning to enjoy catching Kurt unawares. The teasing afterwards is way too much fun. It reminds him a lot of high school when he began to see, after months of instigating and antagonizing, what their daily battle of wits had become - verbal foreplay.

All through Kurt's senior year of high school, poking fun at Kurt became an addiction. Even when Sebastian knew he should keep his mouth shut, even when he realized that what he was doing was getting him nowhere, he couldn't stop. What had started out as a ploy to steal the immensely fuckable Blaine Anderson away from a less-than-worthy adversary became a need for Sebastian.

A need to see the fire that flashed in Kurt's eyes when Sebastian made a sarcastic remark.

A need to see Kurt's chest heave right before he came out with a jab to parry it with.

A need to watch Kurt's pale cheeks flush red and know that Sebastian did that. He put that rush of color there. Soon, when he saw Kurt's face fill with color, he began to imagine that scarlet stain all over Kurt's body.

Their very last angry confrontation occurred after Kurt and Blaine broke up. Kurt came right to Sebastian, ended up on his doorstep at eleven o'clock at night, and they fell into their old routine without Sebastian knowing what had happened.

That evening wrapped up somewhere in the vicinity of four in the morning with him and Kurt in Sebastian's bed.

They'd been dating ever since.

After Sebastian found out about Barry, after he caught Kurt ogling him from across a café patio, the sex that ensued reminded Sebastian a lot of that night, except instead of Sebastian asking Kurt's forgiveness for crossing over a line (which he did with a snide insinuation about Kurt's inability to keep Blaine satisfied), it was Kurt begging for forgiveness.

Then on his hands and knees with Sebastian behind him, pleading for mercy.

Sebastian had been tempted to make Kurt call him Barry, see how his little perv would react, how fuckin' turned on it got him. Sweet, soft, quiet Barry Allen, so scholarly and reserved from what Sebastian could tell. It actually made Sebastian so hot thinking about it while he pounded into his boyfriend, every thrust that missed its mark intended to make Kurt pay for what he'd done, that Sebastian didn't last long.

Jesus fuck! Was Barry Allen going to become a kink for him? Was that deranged? Would he require therapy for this? A support group? An intervention?

Whatever. He'd taken it this far. He saw no reason to turn back now.

Sebastian slips up behind Kurt and wraps his arms around his waist from behind.

"Well, hello, gorgeous," Sebastian whispers, and Kurt, startled at being caught, stiffens in his arms. "And you called me a stalker." Sebastian nuzzles aside Kurt's head and attacks his neck. "Look at you? Tracking our little Barry down. Gawking from a distance like a lovesick puppy. You're so hot to get at him, huh? You wanna put that pretty mouth on him? Wrap your legs around his waist? Make him say your name? Or do you wanna moan his name while I fuck you hard? I'll tell you, babe, I'm getting so many nasty ideas. I think this might call for a little roleplaying later on, don't you think? Or …" He nibbles at the soft flesh beneath the collar of Kurt's shirt, at the muscles rigid as stone "… I've got the Porsche in a parking garage a few blocks away. We can slip inside for a quickie, release some of this tension before we talk to our boy because you, my love, are as stiff as a stripper pole right now. Whaddya say?"

There's something odd in the way Kurt reacts to Sebastian's kisses. Instead of relaxing in Sebastian's arms - melding against his body to feel Sebastian's hard-on press against his ass, bending his neck to offer the length of his smooth skin for Sebastian to mark - his head twists left and right, and he leaps out of Sebastian's grasp.

"Get the hell off of me!" he yells so loud it rings in Sebastian's ears. He spins around and shoves Sebastian full force with both hands planted on Sebastian's chest. The blow knocks the wind from Sebastian's lungs, and he stumbles back a couple of steps. Sebastian trips over his feet and almost falls to the ground, but he manages to recover.

"What the fuck, Kurt!?" Sebastian fixes his shirt and glares at his boyfriend, getting a better look at the man suffering from a severe case of overreaction. It doesn't take more than a glimpse for Sebastian to tell that there's something off about him. Standing in front of him, body locked in a defensive pose, a black canister of Mace in his raised right hand, the man threatening Sebastian looks like Kurt, but only if they were living in an alternate dimension and Kurt were a community college literature professor. He doesn't hold himself like Kurt, and how he glares, his eyes wide instead of narrowed to slits, his teeth clenched with lips parted instead of pinched into a thin line - that's entirely new. The glasses perched on his nose - Kurt would never be caught dead in those glasses. And those clothes. They definitely weren't the clothes Kurt was wearing when he left for work this morning (though he has been known to do a costume change halfway through the day, so that's not weird). But … is he wearing khakis? And a plaid shirt? Maybe Kurt would wear plaid, but that shirt definitely wasn't a McQueen or any other upper echelon designer. Sebastian isn't as in to fashion as Kurt, but he can tell a bargain basement shirt when he sees one.

Sebastian is about to ask Kurt if this is a joke, or did he actually go as far with his fetish as to change his appearance to become someone he thought Barry might like better, until an even more fantastic realization hits him.

"You're … not Kurt, are you?"

"N-no!" the man spits, backing shakily away. "Wh-who's Kurt?" The man seems to finally see Sebastian past his can of Mace and his mouth drops open. Shocked blue eyes look Sebastian up and down. His brow smooths with recognition, then furrows again with fear. "Who ... who the fuck are you?"

Sebastian wants to laugh. He wants to throw his head back and break down until tears leak out of his eyes and he can't breathe, but he's afraid he might get Maced if he does.

"Holy shit," he murmurs, looking the man over, completely stunned by what he's seeing. If Sebastian thought that finding a man that looked exactly like himself was impossible, what would the statisticians of the world make of this coincidence?

"Carson?" Barry appears, rushing over to the frightened man's side. "Are you ... Sebastian?" Barry raises an eyebrow. "I didn't know ... I didn't realize you two had met."

Barry puts his arm around the man's waist. The man turns his head to look at Barry, staring at him as if they're all going insane, himself especially.

"B-Barry?" His eyes dart from Sebastian to the man by his side so quickly that Sebastian would be surprised if he doesn't give himself a headache. "Do you ...?" He shakes his head, not sure what he wants to ask, what question will solve this mystery. "Who is this!?"

"Bar-ry," Sebastian sings, feeling safe to lower his arms, "you've got some 'splaining to do."

"Uh … yeah," Barry agrees. Carson's fuming eyes demand an explanation while Sebastian smirks at the two of them like he just caught them doing something wildly inappropriate. "Maybe I should introduce you two?"

"I think it's the least you could do," Carson snaps.

Barry clears the discomfort from his throat. "Sebastian Smythe, this is my boyfriend, Carson Phillips. He's a journalist for The Central City Citizen. Carson, this is Sebastian Smythe. I met him here in New York a few days ago. I …" Barry pauses, his expression puzzled. "I'm not exactly sure what you do for a living."

"No one does," Sebastian jokes, hoping to diffuse the stress from the man with his finger stuck firmly to the dispenser button of his Mace. "It's nice to meet you." Sebastian leans forward and extends a hand. "I apologize about before. You just look … well I mistook you for …"

Carson stares at Sebastian's hand as if it's an inimical, pus-strewn monster, and takes a reflexive step away, dragging Barry with him.

Sebastian pulls his offensive hand back, wringing it with his other to hide it from view.

"Maybe it would be better if I called Kurt and we all ate lunch together," Sebastian suggests. "Get this all out in the open once and for all, hmm? What do you guys think?"

"I think that's a good idea," Barry says. He pauses, waiting for Carson to jump in with a barrage of questions or a scathing rant, but his eyes are still wide as saucers, bouncing from Sebastian to Barry, his mouth hanging ajar.

"O-kay." Sebastian reaches into his pocket for his phone. "Just … give me a second."

"Of course." Barry walks Carson away a few paces to explain Sebastian to him in private. Sebastian watches them as he dials Kurt's number. Barry gazes into his boyfriend's eyes as he talks with Carson shaking his head in disbelief, shooting the occasional unreadable glance Sebastian's way.

"Sebastian?" Kurt picks up without Sebastian noticing, so drawn into the conversation between Barry and Carson that he can't even overhear.

"Kurt? Babe? Can you come downtown for lunch, say, now?" Sebastian watches Barry put his arms around his boyfriend, a surreal ping knocking in his chest from watching these two men, who look so much like him and Kurt, embrace. "No," he says when Kurt asks if there's something wrong. "Everything's alright. There's something you have got to see."

"What is it?" Kurt asks, the telltale sounds of him heading out of his office, down the hall, and into the elevator audible through the phone.

"I'd rather you see for yourself," Sebastian says. "Let's just say that Barry Allen's been holding out on us.
