This came from a variety of inspirations – a Sebastian/Sherlock crossover fic I read, the TV series Chuck, and a photoset made by the tumblr user cooperbastian. I've fallen in love with this AU verse more than I expected to! There's a second part coming soon.
Please let me know what you think of the fight scene! I've never written one before and I'd greatly appreciate the feedback.
Cooper was just putting the frozen pizza in the oven when the doorbell rang.
"Cooper, can you get that?" Blaine called from his room upstairs.
"I got it," Cooper yelled back as he set the timer for the pizza. He was mildly curious who it was, as it was just supposed to be him and Blaine tonight. It was one of those rare times when Cooper was visiting and their parents were out at some function or other. He and Blaine were supposed to be having a brotherly bonding session with movies and pizza.
Cooper opened the door with a smile but then tensed immediately when he saw who was on the other side. He could see the exact moment when Sebastian recognized him as well – his face went from a nonchalant smirk to surprise. Sebastian was the first to react to the unexpected situation as he flung what appeared to be a DVD case at Cooper's head. Cooper ducked and grabbed hold of Sebastian to yank him inside – the last thing he needed was the neighbors seeing this.
Sebastian let himself be forced into the house but as Cooper slammed the door closed Sebastian stepped around him to viciously elbow him in the back. Cooper winced and lost his grip but immediately turned to punch Sebastian in the jaw. Sebastian blocked the punch and kneed him in the ribs. Pain erupted in his side but Cooper ignored it, concentrating on sweeping Sebastian's legs out from under him. The move worked and Sebastian crashed to the floor.
Cooper reached for the knife that he had attached to his lower back, right above the line of his jeans. It was missing. Cooper cursed as Sebastian rolled away from him and back to his feet. Cooper's knife was in his hand – he apparently nicked it when he elbowed Cooper in the back. "Missing something?" Sebastian taunted him as they faced off.
"You mean like a challenge?" Cooper retorted, his mind whirling with questions, moves, escape routes, and Blaine's location. Also places to hide Sebastian's body.
Sebastian sneered but didn't lunge for him at the insult, which is what Cooper had expected. He had apparently learned a few things since last time – damn it.
"Where's Blaine?" Sebastian demanded angrily.
"As if I'd tell you." Please Blaine, don't come down. Don't hear this, Blaine. This was exactly the situation that Cooper had been dreading and having nightmares about for years. Someone had finally figured out his secrets and had come for his brother. Were his parents still safe?
Sebastian was apparently tired of talking and sprung from his spot at Cooper. Cooper deftly evaded the knife, grabbed Sebastian's wrist, and rammed his shoulder into Sebastian's body. He twisted the wrist until Sebastian was forced to let go of the knife – it clattered to the floor. His victory was short-lived as Sebastian's other arm wrapped around his neck, choking him.
Cooper hated that Sebastian had a height advantage.
Cooper elbowed Sebastian in the gut which loosened the arm around his neck. He twisted out of the hold and sent Sebastian flying back with a kick. He snatched the knife from the floor but didn't attack Sebastian. Instead, Cooper raced over to armchair in the living room and ripped the seat cushion open with it. He reached into the stuffing and pulled out a gun. Before he could turn around and take aim, Sebastian tackled him to the ground. Cooper dropped the knife but kept hold of the gun, and now he and Sebastian were grappling for control of it.
As they rolled around on the floor, one of Sebastian's legs knocked over a lamp. The resounding crash meant nothing to either of them, but both Cooper and Sebastian froze when Blaine called out, "What was that?" With renewed energy and approaching sense of panic, Cooper elbowed Sebastian in the side of the face. Sebastian cursed but exploited the weakness it created on Cooper's grip on the gun – Sebastian got complete control of it. Despite Cooper's frantic efforts, Sebastian was able to disentangle himself. Cooper was kicked away and they both rolled to their feet some distance apart. Cooper had managed to pick up the knife again when he had rolled, but Sebastian had the gun trained on him.
This was the scene Blaine walked into – Sebastian holding his brother at gunpoint. Blaine froze at the doorway, eyes wide.
"Blaine. Hey," Sebastian greeted calmly, breathing heavily. His eyes stayed trained on Cooper.
"What the hell?" Blaine asked, finally being able to articulate words.
"Walk away, Blaine. Please, just walk away," Cooper tried to plead with his brother, but he too never took his eyes away from Sebastian.
"Sebastian what are you doing? Why are you pointing a gun at my brother?" Blaine cried out.
"I'm – he's – wait…he's your brother?" Sebastian said, going from hard and controlled to complete surprise. Cooper could see his utter shock - and then Sebastian's faze flicked to Blaine as if to confirm the truth.
That's when Cooper struck. He kicked the gun out of Sebastian's hands and tackled him back to the ground. Cooper had the definite advantage because of Sebastian's confusion. After only a brief struggle Cooper was sitting on Sebastian's back, one hand holding Sebastian's arms behind him and the other a knife to his neck.
"Now, what the hell are you doing?" Cooper snarled at him.
"Cooper!" Blaine yelled in shock again.
"Walk away, Blaine," Cooper ordered. Blaine wasn't listening, though, as he never moved from his position. "Answer the question, Sebastian."
"I didn't know Blaine was your brother. I thought he was your target," Sebastian said through gritted teeth. He squirmed but Cooper kept him in his secure grip and responded by pressing the knife harder against Sebastian's skin.
"If you didn't know we were related, why are you targeting him?" Cooper asked.
"What?" Blaine gasped.
"I'm not," Sebastian responded stiffly. "I was returning that fucking DVD he left at Dalton."
"Who is your target?" Cooper pressed. The problem was he had no idea if Sebastian was telling the truth or not.
Sebastian didn't respond. Cooper pushed his knife harder into Sebastian's skin, drawing small drops of blood. "Who is your target," Cooper hissed with more ferocity that time.
"I don't have one," Sebastian finally gritted out. "I'm off-case."
"No one goes off-case," Cooper scoffed. "Now answer the question or I'll assume Blaine is your target and kill you right here." Blaine let out a choked cry but Cooper didn't even spare him a glance.
"I don't have a target," Sebastian said forcefully. Cooper then heard him sigh before Sebastian's body went lax underneath him. He tightened his grip in case it was a ploy. Sebastian's next words were spoken softly, almost in defeat – "I've been off-case since Paris."
Paris. Cooper was hit with realization – but knew better than to loosen his hold on Sebastian. Sebastian didn't try to free himself, though, even though the words would be a huge distraction.
"Derek," Cooper whispered. "That was Derek in Paris?"
Sebastian nodded – the movement causing blood to run more freely from where Cooper had pricked him.
"Shit," Cooper said softly. He had liked Derek. Sure, they worked for different corporations and had crossed paths under some bad circumstances, but Derek and Sebastian had been his favorite pair to run across in the business. Usually agents didn't take each other out, even if they were the competition. Derek and Sebastian had left Cooper and Sarah (his own partner) tied up outside a police station – not a big deal except they had also been framed for grand robbery. It had definitely been a headache to get out of. Cooper and Sarah had gotten them back in Colombia; they were actually after different targets, oddly enough, but Cooper and Sarah had messed with their vehicle anyway, causing Derek and Sebastian to be stranded in an extremely remote village that had poor cell reception. The next time the teams ran across each other they spent the night buying each other drinks and hanging out before going their separate ways the next morning. They had formed an odd sort of friendship – though not one that would stop Cooper from killing them if they had come after Blaine or any of his family.
But something had gone wrong in Paris. He had only heard rumors of what had happened since he'd been back from an extremely lengthy undercover case in China. And before he could be briefed on the entire story, he and Sarah had been given a short break so that Sarah could attend a family wedding. He only knew that Paris had been a brutal, bloody mess – one which left an agent's mangled body hanging off a bridge. Apparently it had been Derek.
"Shit," Cooper repeated, getting off of Sebastian. "That sucks." Cooper heavily doubted that even Sebastian would joke about that being Derek. Their jobs were dangerous – but more so from stray bullets than gory public displays. Normally it was the targets who died…not the agents. And for Sebastian to lose Derek…
"Yeah," Sebastian said, picking himself off of the ground. He rubbed some of the blood off of his neck. Cooper grimaced – Sebastian was definitely more subdued with the reminder of what must be extremely painful memories.
"Okay. I'm going to say it again. What the hell?" Blaine interrupted.
