Ch. 10

-SPN/NCIS-

Dean checked the doorknob and, seeing that it was locked, knelt down, pulling out a few small tools. After a few seconds the lock clicked and Dean grinned, satisfied.

"How did you learn to do it that fast?" Tony whispered as he inched closer to Dean. Dean turned, still grinning.

"Lots and lots of practice." Dean said before moving into the house, all of his senses on alert. Castiel tapped on his shoulder as they entered the living room, and Dean turned.

"I sense they are in that room." Castiel said, his deep voice rumbling through the house even through he was speaking quietly. Dean nodded, heading to the door of the room Castiel had indicated. Dean almost jumped when a voice yelled from behind the door.

"I know you're out there, Dean. If you or your little angel boy toy come in, this will not end well for your precious little brother." The female vampire yelled, and Dean could hear the smile and the treat in her voice. Dean made up his mind quickly.

"Alright, I'm just going to open the door so we can talk more easily." Dean said, even though he knew there wouldn't be too much talking being done if something happened to Sam.

When she didn't say anything in reply, Dean's hand wrapped around the doorknob and he turned it slowly, letting it swing open as he armed himself again with a stake and his favorite gun. Suddenly, the hair on the back of his neck stood on end. He only felt like that when he felt he was being watched.

"Did you think I'd be here alone, Dean?" came the vamp's sudden question. The sneer on her face was enough to make Dean bolt toward her, filled with rage. That was when everything went wrong. As soon as Dean moved, the whole house was filled with Vamp's.

Dean swore as he sliced through the neck of one vamp, cutting his head clean off when he hit the floor. It didn't occur to Dean that the noise he could hear over the snarling was the laughter of the one who had Sam.

He struggled to keep from going right for Sam, instead turning to the NCIS team who seemed to be having some trouble.

Tony was slicing and firing away at a vamp that had come up behind Ziva when she had her back turned. Ziva was fighting two vampires at once, and actually had the upper hand. Dean had to give her some credit, she was pretty good. McGee wasn't doing too badly himself, though he seemed to be having a particularly hard time with a vicious male vamp who was giving him a run for his money. Gibbs however was nowhere to be seen. Even when Dean sliced his way through to the other side of the house, he hadn't once caught a glimpse of the old man anywhere in the fray. Castiel had stayed back near the room, slicing his way through vamps with his angel blade.

Through all of his looking and slicing, Dean had failed to notice that he was being followed by a particularly menacing looking vamp.

He stopped after cutting down three vampires at once, grinning triumphantly, when he heard the slight hiss of a blade slicing through the air, and then a loud thump behind him. Dean turned around quickly to see Gibbs standing over the vampire. Something silver flashed near his sleeve, but by the time Dean's eyes got there, whatever it was had disappeared. Gibbs looked up, a grim look on his face.

"You missed one." He said, and the deadpan tone of his voice was something that competed with Castiel's when he had first come to Dean. Dean nodded, his face serious, before he turned back around quickly.

"Cas, Sam, you ok?" Dean yelled, because he couldn't see either anymore. He waited, and almost began to dread the answer.

"Yeah, We are fine, Dean." Castiel's reply came from the bedroom. Dean ran over, pushing the door open all the way to see Castiel, standing behind Sam who was strapped to a chair, and the female vamp on the floor. Castiel untied Sam, who stood up, rubbing his wrists.

Dean approached the body of the female vamp, his eyes looking down at her. Castiel's angel blade stuck out of where her heart would be, and she seemed to be paralyzed.

"I guess you were right. Someone is going to die, and it's not me." Dean said quietly before kneeling down, a long, wicked knife in his hand. She actually laughed, her sharp teeth protruding out of her mouth as she grinned, blood trickling from her mouth.

"It won't matter. You cut one of us down, another will pop up." She wheezed, her lungs filling fast with blood. Dean nodded, his face serious.

"Yeah? Then I'll be there to keep cutting them down."

The blade was sharp, but he still had to put some weight behind it as he sliced her head off. He stood up, the bloodied knife still in hand, and stared at her dead body for a minute.

He turned to Sam after that, a grin breaking out across his face as he held out his hand like he wanted something.

"Time to pay up, Sammy. I won, again." Dean said as he grinned. Sam shook his head, but couldn't help the smile that spread across his face as he pulled out his wallet, took out a twenty, and handed it to Dean.

The NCIS team watched from the doorway, dumbfounded (except for Gibbs, who's face was straight), as the two grinned at each other, then began to laugh. When their laughter finally died down, Dean glanced at the door.

"So, you care to explain why you are laughing?" Gibbs asked, and Dean actually almost grimaced and averted his eyes.

"Sorry. So, you guys did pretty well for never having done anything like this before." Dean said with a smirk. Tony returned the smirk, adding a flash of teeth.

"Guess you underestimated us then?" He said, and was surprised when Dean shook his head.

"Not at all actually. I thought you guys would do well from the beginning. You have good heads on your shoulders, so I knew you could take care of yourself." Dean said with another smile, winking at Ziva, who grinned at Dean, glancing almost quick enough for Dean to Tony, before turning around and heading out of the doorway.

"If I didn't know any better, I would think you guys were all hunters." Sam said, his tone sprinkled with a bit of confusion.

"You do not know how right you are, Sam." Castiel said cryptically, making the team shoot him questioning glances. Castiel sighed, like what he was about to say should have been obvious.

"Amazingly, all of you actually come from a line of hunters, even if the line is back far in your bloodline's. The gift often skips generations, but all of you seem to have inherited it." Castiel said, sounding for all of the world like he was teaching preschoolers.

Now it was Dean and Sam's turn to look confused. They both turned to Castiel, their expressions asking the questions they didn't voice.

"It would seem that someone went through a lot to put this particular team together." Said Cas, glancing at Gibbs as he talked. The old man's face stayed straight and unreadable, but Dean could feel his suspicion climbing.

-Back at the NCIS Office-

Dean watched Gibbs carefully from where he stood outside of the bull pen, his arms crossed as he leaned against the wall. Something about Gibbs seemed familiar, but in an alien way. He couldn't quite put his finger on it, but he knew the knowledge of the real Gibbs was in his mind somewhere.

Quickly, he pulled Tony aside, thinking that he might know something that could shed some light on the situation.

"Hey, have you ever seen Gibbs do anything….weird? You know, something that seems impossible? Like just appearing somewhere, or something?" Dean asked, being sure to keep his voice down. Tony seemed to consider the question, before coming to a conclusion. He studied Dean for a moment, seeming to weight out if he could trust him or not.

"Well, he does seem to be able to appear out of nowhere at just the right time, like when Abby has something for him. And he does seem to know, most of the time, where the bad guys are." Tony said, his expression still suspicious. Dean nodded, and it was then that what Gibbs might be popped into his mind. He didn't let this show in his expression though. He kept his face straight, his eyes still on Gibbs.

"Alright, I guess we should be on our way." Sam spoke up from his spot leaning against McGee's desk. They had been discussing the best way to hack into military databases. Dean nodded as he pushed himself up from the wall he was leaning against with Tony.

"Sam's right. Lots more baddies out there for us to get to." He said nonchalantly, like it was the most normal thing in the world. Gibbs nodded, his eyes moving over Dean, Sam and Castiel, before waving towards the elevator.

"Thanks for the help. The way out is there." He said, not trying to sound harsh. Dean nodded once, and after he and Sam said their goodbyes, they left the Navy yard. Gibbs looked down at his desk before they left, and he noticed a note taped to his desk.

"Here's my number, in case you guys run into something like this again, Old Man." Dean had written, along with a cell phone number. Gibbs grinned, shaking his head as he sat back, looking at the ceiling as he continued to smile. Despite the attitude, he had to admit, he liked the kid.

Authors Note; So there you have it! The end! :D Just kidding! xD There will be another chapter to clear up the whole Gibbs business. And if you want it, more of the after math of Tony and Ziva ;D Tell me what you think! :D
