As if it was clockwork, Sebastian sauntered through the door with a smirk on his face. Kurt couldn't suppress a grumble. He always had hated those stupid smirks of his. He stayed out of sight and watched Sebastian order his coffee. After he got his order he had started looking around the room, obviously looking for someone in particular. After a couple of minutes, Kurt couldn't wait any longer, so he stood up and walked up behind Sebastian. He even cleared his throat a little, attempting to draw attention to himself, but it didn't work. Sebastian had a one track mind.

"Blaine's not coming," Kurt said from behind Sebastian.

Sebastian turned around to look at Kurt, recognizing that voice instantly. Sebastian put on his proud smirk and gave Kurt a once over. "I'm surprised he even told you about this. Aren't you two supposed to be fighting?" Sebastian asked with a slightly cocky tone.

"We are, and he didn't," Kurt replied as nonchalantly as he could. Sebastian gave him a confused look, wondering how Kurt knew about the get together if not from Blaine. "He didn't tell me because he doesn't know about it. I was the one you were messaging last night."

"I see, and what were you doing on Blaine's Facebook?"

"That's for me to know," Kurt retorted a little harshly.

"Hacking into your boyfriend's Facebook," Sebastian said. "Color me stunned."

"I didn't hack. He gave me his password months ago."

Sebastian nodded in acknowledgement. "So, if you're the one I was messaging with last night, then you're the one who wanted to see me for some reason. Care to tell me what that reason is?"

Kurt knew this was why he had asked to meet Sebastian, but he still didn't want to say the words. He hated the idea of doing this, but he really couldn't come up with a better idea. "I have a favor to ask of you."

Sebastian chuckled. "You're joking, right?"

"If you hear what I have to say, and you're not interested, fine, but just hear me out."

"Why should I?"

"How about we start with the fact that I'm the only reason you're pretty boy ass didn't go to juvie last year," Kurt replied icily.

Sebastian's face dropped, the almost constant smirk disappearing instantly. "Fine."

Kurt turned on his heel and walked back to the table he had previously occupied. Sebastian followed and took a seat across from where Kurt was sitting. They stayed quiet for about a minute, each one just watching the other. It was as if they were trying to size each other up without even realizing it. It was at that very moment that Kurt realized he was dreading this conversation. He hadn't thought this thing through fully last night and was only just realizing how much this conversation was going to suck.

"So what's this favor?" Sebastian finally asked in a dead panned voice.

"In order for you to understand the favor, you're going to need some backstory," Kurt said, which caused Sebastian to open his hands as if to tell Kurt to be his guest and give him the backstory. "I know you know Blaine and I are having trouble. Do you know why?"

"No. Either the guys didn't know, or they just weren't telling me."

Kurt watched Sebastian silently for a few moments. He still hated hearing himself admit the hard fact out loud, and the idea of telling Sebastian, the one person who would probably be happy to hear such news, made Kurt sick. His stomach clenched at the thought of telling Sebastian about Blaine's infidelity, but he knew it had to happen. He took a deep breath and decided he would just do it as quickly as possible, just like taking off a Band-Aid.

"Blaine cheated on me," Kurt blurted out.

Sebastian went wide-eyed at Kurt's revelation. He was not expecting to hear that at all. He knew Kurt had moved to New York a couple months ago (the Warblers really did like to gossip) so he assumed the couple just wasn't handling the distance well. After how hard Sebastian had tried with Blaine last year, he figured Blaine just wasn't the type to cheat. He never thought he would hear that he actually ended up fooling around on Kurt. After all, Blaine had told him that he never wanted to do anything that would mess up what they had. He was always very adamant that he wasn't going to do anything that could hurt Kurt. If it hadn't annoyed Sebastian so much, he probably would have admired it.

"Wow," he finally said, unable to really think of anything else to say. "How'd you find out?"

"He admitted it to me," Kurt replied.

"Oh," Sebastian said a little disappointed. He had been hoping for more drama. It took took him another minute of dumbfounded shock before he could get back to the issue at hand. "As fun as it is for me to hear about this, what does this have to do with me? He didn't cheat with me."

"I know he didn't," Kurt answered quickly. Sebastian didn't need to know that Kurt had feared that initially.

"So how did I get involved?"

"Now is when I ask you for a favor."

Kurt paused again, surveying Sebastian carefully. As much as he hated the man, he could acknowledge his attractiveness and why someone would be interested in him, and he knew he would be willing to do what Kurt was about to offer. It was only then that Kurt realized he had no idea what he would do if Blaine failed his "test," especially if that meant he had done something with Sebastian. Until he reached this point in the conversation, Kurt had thought Blaine cheating was the worst thing in the world, but now Kurt saw that, to him, Blaine cheating with Sebastian was the worst thing. That had been a nightmare of his ever since that man entered their lives.

Kurt took another moment to consider what he was doing. Did he really want to set himself up for this potential heartbreak? Keeping hard eyes on Sebastian, he let out a mental huff. He had to know.

"I want to forgive Blaine, but I don't trust him. I want to test his faithfulness," Kurt said.

Sebastian looked at Kurt without responding. Kurt was being too vague, and there could be no misunderstandings here. Sebastian needed Kurt to actually say what he was trying to say. He had no idea where Kurt was going with this or why he was involved.

"I want you to seduce Blaine," Kurt stated with a surprisingly calm voice.

Sebastian gaped at Kurt, not even attempting to hide the shock. His eyes were wide and his jaw had literally fallen. He normally liked to keep himself composed, especially around people he didn't like, but he couldn't contain how dumbstruck he was. That was definitely the last thing he was expecting Kurt to say. Truth be told, he had no idea what Kurt was going to ask of him, but there was no way he thought it was going to be that, especially not after how everything was last year.

"You want me to what?" Sebastian asked once he found his voice again.

"You heard me," Kurt replied. "I want to know if I can trust him again or if he's going to cheat on me again."

"So you're going to set him up to cheat."

"Yeah, and see if he takes the bait."

"Okay," Sebastian said slowly as if he was still trying to wrap his head around this conversation. "Why am I the bait?"

"'Cause I don't think you were entirely wrong last year," Kurt replied, hating to admit this aloud. "I don't think he was interested enough to do anything while I was here, but I do think he was interested in you, and, with me in New York, he'd be most tempted by you."

That small unintentional compliment from Kurt was all Sebastian needed to gain control of himself again. He finally managed to gain some composure back as he let the idea fully sink in. Kurt WANTED him to seduce Blaine. The idea actually sounded kind of fun, so fun that Sebastian wished he could just say "yes" and leave it at that, but he was too curious and had too many questions.

"What makes you think he'd go for it?" Sebastian asked. "I mean, he didn't last year, and that was before the…incident."

"Incident? That's what you're calling it?" Kurt retorted.

"Whatever you want to call it, the question remains. What makes you think he'd go for it now when he didn't before?"

"Because I'm not here now. I was before."

"Okay," Sebastian said with a nod. That sort of answered his first question, but he had more. "Why should I do it? What do I get out of this?"

"The chance to potentially fuck my boyfriend," Kurt replied coldly.

Sebastian felt things low in his belly tighten at Kurt's words. He couldn't deny that that was something he had been wanting to do for a long time, pretty much since the first time he laid eyes on Blaine. The idea of finally getting to have Blaine turned him on more than it should have. He didn't fully understand why Blaine turned him on more than anyone else, but he did. Sebastian couldn't hide the desire from showing on his face.

"I know you still want to," Kurt said knowingly. "It must just eat you up that he turned you down."

"All because of you," Sebastian said with a grimace.

Kurt gave a small smile. "All because of me," Kurt said fondly. "Here's hoping he does it again."

"Speak for yourself. I want him to fail miserably."

"Does that mean you'll do it?"

"A few more questions first."

Kurt let out a little huff but waved for Sebastian to continue.

"How do you know I'll tell the truth?" Sebastian asked.

"Because if you do manage to get Blaine, you won't be able to stop yourself from rubbing it into my face," Kurt replied simply.

Sebastian shrugged. He couldn't really argue Kurt on that logic. It had been a long time since he had wanted to honestly tell Kurt that he lost, that Blaine chose him, that they had fucked their brains out the night before. It wasn't that Sebastian hated Kurt, it really wasn't. Sebastian didn't think much of him, true, but he didn't hate him. He saw him as an obstacle, something that got in the way of him getting what he wanted. He was just the thing that prevented him from getting Blaine.

"I can't really disagree there," Sebastian said which caused him to be on the receiving end of a cold Kurt Hummel glare. He could only smirk in return. "What if I don't get him? How do you know I won't just tell you I did so you cut him out?"

"There would be no point in lying to me."

"Really? I lie to you about this, you think he cheats on you again, you break up with him, and he goes crawling to someone he knows is interested in him. Seems fairly pointed to me."

Kurt gave a knowing smile. "You might be able to lie to me, but Blaine can't. If I called him out on you two getting together, and you guys didn't, I'd know just from his reaction."

Sebastian's face fell a little. "You're actually going to call him out on it if he does it?"

"Yes," Kurt replied. "So, like I said, there would be no point in lying to me because I would know the truth just from Blaine's reaction."

Sebastian grumbled. "Fine. One more question and then you'll have your answer. Don't you feel bad doing this?"

Sebastian didn't know why he wanted to know, why he even cared, but he did. He may not have known Kurt well, but he still didn't think this was something he would do. Maybe being cheated on made him more heartless; maybe he grew up some from his time in New York; maybe the separation had taken its toll on him. He didn't know what it was.

"Yes," Kurt answered without hesitation.

"Then why are you doing it?" Sebastian asked.

Kurt sighed. He wasn't sure he could explain this, especially not to Sebastian. He probably wouldn't be able to explain even to Rachel. He could barely understand why he was doing this himself. He knew all the potential downsides to what he was doing. He could very well be setting himself up for devastation. He wasn't sure he could handle Blaine cheating on him again, especially not with the man sitting across from him. It would be the ultimate betrayal. He knew if it happened it would be the end of him and Blaine. There would be no going back after that. But there was also one very big upside to his plan. If Blaine could turn down advances from Sebastian, one person Kurt knew Blaine had been somewhat interested in, despite what he claimed, that would mean he meant everything he was saying. If Blaine wouldn't cheat with Sebastian, then Blaine wasn't going to cheat. In Kurt's mind, it all made sense.

"I have to know, Sebastian," Kurt said. "After what happened, I don't want to just sit around wondering if he's going to do it again. I need to know I can trust him before I can really forgive him."

"You know this won't be the end all and be all of this," Sebastian said. "He could turn me down and still go with someone else."

Kurt shook his head. "If he turns you down, when you're actively trying to get him, then he'll turn down just about anyone. Trust me."

Sebastian shrugged. He still thought Kurt was putting a little too much faith in his "test," but he wasn't going to argue with him about it. He shouldn't be trying to talk Kurt out of going through with this anyway. Sebastian actually liked the idea. He knew it was going to be a little challenging to get Blaine to want anything to do with him at first, but he also knew that once he got Blaine talking to him, everything else would be fun and easy.

"How are we going to do this then?" Sebastian asked.

"I'm going back to New York on Monday," Kurt answered. "That's when your work's going to start."

"Are you going to still talk to him?"

"Yeah, but I doubt it will be like it was before."

"You know that's just going to make my job easier."

"I know, but I'm still not…okay with him."

"How are we going to stay in contact? I'm going to need some way to keep you updated besides Blaine's Facebook."

Kurt sighed. He didn't like the idea of giving Sebastian his number, but he knew he had a point. Sebastian had to tell him what was going on someway. Kurt took his phone out and brought up a text message, punching in his own number. He set the phone down on the table, facing Sebastian, so he could read the numbers. Sebastian figured out what Kurt was doing and took his own phone out, punching the numbers in and adding Kurt to his address book. He sent Kurt a blank text message so Kurt could have his number stored too.

"I don't need you to tell me every little detail of every time you two talk or see each other," Kurt said. "I just need to know if Blaine falls for you. I'll text you periodically to ask how things are. Other than that, just let me know if something happens."

"Is there a time limit?" Sebastian asked.

"I'm due back home for Thanksgiving. You have until then. That gives you a month."

Sebastian's smirk was in place when he said, "Alright."

Kurt couldn't hold back and eye roll and a grumble at how happy Sebastian seemed. He knew he would like the idea of chasing Blaine, but he had no idea he would be that obvious about it. He thought he might have at least attempted to hide it, but he was wrong. Sebastian sat there with a smirk playing at his lips and a twinkle in his eyes as he thought of all the different things he wanted to do with Blaine.

"I'll talk to you later," Kurt said and got up to leave.

"Aren't you going to wish me luck?" Sebastian asked.

"No," Kurt bit back and walked out of the coffee shop.

Sebastian took another drink of his coffee and let a small chuckle out. This is going to be fun, he thought.

-:-:-:-:-

Kurt sat in the passenger seat of Finn's car, glancing over at the man driving periodically. He hadn't been home from the Lima Bean for more than half an hour when Finn came and got him and told him that he needed his help. Kurt was more than a little wary because Finn wouldn't elaborate. No matter how many times Kurt had asked, Finn would just tell him it was something for Glee club. Kurt had thought seriously about not going unless Finn explained, but he couldn't do that. Even though it wasn't his Glee club anymore, he would still help them if he could.

They pulled up in front of the auditorium entrance and got out of the car.

"Finn, are you going to tell me what we're doing here?" Kurt asked.

"I just need you to see something," Finn replied, still avoiding telling Kurt what exactly what was going on.

"You need me to see something in the auditorium?" Finn nodded. "How are we even getting in there? It's Saturday."

Finn took keys out of his pocket and shook them. "There are perks to running the Glee club right now."

"What am I seeing?" Kurt asked as they walked through the door.

"A performance."

Finn had led Kurt to the seats and was trying to convince him to sit, but Kurt stayed standing. He could tell Finn was up to something, and he was getting more and more suspicious about what it was. "What kind of performance?" he asked with an edge to his voice.

"Just watch," Finn said as he took a seat and turned his eyes to the stage.

Kurt kept his eyes on Finn for a few moments before he cast his eyes to the stage. He had a nervous lump in the pit of his stomach. He didn't know exactly what was going on, but he dreaded what was about to happen because he had a feeling that it had something to do with Blaine. Kurt didn't know what to expect as he looked at the stage, but he knew he was either going to really like it or really hate it.

The music started playing, and Blaine, Sam, Brittany and Tina walked onto the stage. Brittany and Tina started harmonizing the beginning of the song; Sam took a spot next to them; and Blaine took a few steps forward and locked eyes with Kurt. Knowing the song almost instantly from the music, Kurt quickly figured out who was going to do be doing what on that stage. Blaine would be singing lead; Sam would be backing him up; and Brittany and Tina were there for the harmonies.

Kurt smiled at the song choice. He was the one who first introduced Blaine to "Angel With A Shotgun." He had been the one to convince Blaine that it was a love song. He had been the one in love with the song. He had never expected Blaine to use that song against him. Kurt remembered what he had told Blaine about this song though. Not only did he explain that it was a love song, but he told him it was about someone fighting for their love, for the person they wanted.

"I'm an angel with a shotgun, shotgun, shotgun, angel with a shotgun, shotgun, shotgun.

Get out your guns, battles begun. Are you a saint or a sinner?

If love's a fight, then I shall die with my heart on a trigger."

Blaine kept his eyes on Kurt as he sang. He knew Kurt would recognize the song, knew that he would understand what he was trying to say. Blaine hadn't expected to be nervous, but he was. He wanted this to be perfect, needed this is to be perfect. He knew it wouldn't fix everything, knew it wouldn't get him Kurt back, but he needed to show him that he wasn't giving up. Blaine needed Kurt like he needed air, and he wasn't going to give up on him without one hell of a fight. He needed Kurt to understand that he would do anything, be anything, for him.

"They say before you start a war, you better know what you're fighting for.

Well, baby, you are all that I adore.

If love is what you need, a soldier I will be.

I'm an angel with a shotgun, fighting 'til the war's won.

I don't care if heaven won't take me back.

I'll throw away my faith, babe, just to keep you safe.

Don't you know you're everything I have?

And I wanna live, not just survive, tonight."

Kurt was finally able to move into a seat by the end of the first chorus. He couldn't take his eyes off of Blaine though. The way Blaine's perfect hazel-brown eyes bore into him was making it hard for him to breath. Blaine was doing a wonderful job with the song, and the raw expression on his face was letting Kurt see just how much he meant what he was singing. Kurt always thought Blaine portrayed what he was feeling best with music, and he loved hearing that man sing. It was almost enough for Kurt to forgive him…almost.

"Sometimes to win, you've got to sin; don't mean I'm not a believer.

And Major Tom will sing along, yeah, they still say I'm a dreamer.

They say before you start a war, you better know what you're fighting for.

Well, baby, you are all that I adore.

If love is what you need, a soldier I will be.

I'm an angel with a shotgun, fighting 'til the war's won.

I don't care if heaven won't take me back.

I'll throw away my faith, babe, just to keep you safe.

Don't you know you're everything I have?

And I wanna live, not just survive, tonight."

Kurt caught himself smiling and moving slightly to the music, but he didn't force himself to stop like he knew he should have. Blaine noticed the smile and saw the small spark it Kurt's eyes. He missed seeing that spark so much, missed seeing how it caused his already beautiful blue eyes to lighten just a little. It was the first time he really saw that spark since he showed up in New York. Blaine smiled at seeing Kurt that way. So far, it seemed like his plan was working, and he let himself relax a little.

"Ooohhh, ooohhh whoa whoa oooh whoa

Ooohhh, ooohhh whoa whoa oooh whoa

Ooohhh, ooohhh whoa whoa oooh whoa

(I'm an angel with a shotgun, shotgun, yeah)

Ooohhh, ooohhh whoa whoa oooh whoa

(I'm an angel with a shotgun, shotgun)

Ooohhh, ooohhh whoa whoa oooh whoa

I'm an angel with a shotgun, fighting 'til the war's won.

I don't care if heaven won't take me back.

I'm an angel with a shotgun, fighting 'til the war's won.

I don't care if heaven won't take me back.

I'll throw away my faith, babe, just to keep you safe.

Don't you know you're everything I have?

(I'm an angel with a shotgun)

And I want to live, not just survive.

(Live and not just survive)

And I'm gonna hide, hide, hide my wings tonight."

Kurt kept his eyes on Blaine intently as he came to the end of the song. He almost felt bad that he had completely ignored everyone else in the room, but he couldn't fully bring himself to care. This wasn't about anyone else except him and Blaine. He even liked the slight time changes Blaine had to make to the song to keep himself the lead the whole time. Blaine had understood that the message wouldn't mean as much if it had come from someone else. Kurt needed to hear Blaine's voice as much as possible for everything to be properly communicated.

"They say before you start a war, you better know what you're fighting for.

Well, baby, you are all that I adore.

If love is what you need, a soldier I will be."

Blaine and Kurt locked eyes again and it seemed like time froze for a few seconds. Blaine had just poured his heart out on that stage, hoping against hope that Kurt would understand. Kurt could see everything Blaine was feeling. He very rarely saw Blaine that exposed. He wanted nothing more than to go hug him, tell him everything was going to be okay, tell him that he loved him and wanted to be with him forever, but he couldn't do that. He had gotten Blaine's message loud and clear though, and he was more than willing to give Blaine the chance to prove that he meant every word.
