SHIELD and NCIS United c22

McGee walked through the corridor heading past the stairs and into the ballpien not liking this idea at all it had been two hours and he was tense he felt guilty over the fact that others were in danger. Gibbs was in a room with Tony and Ziva while the SHIELD agents were doing who knows what. Dalilah was off with Abbey and Ducky sighing again he made his way over to the elevator when he stopped there was an agent standing against the cubical one Tim did not recognize.

Already on alert he was ready when he lunged at him jumping out of the reach of a knife blocking his next attack putting space between them giving him the chance to look around no one was near. He couldn't think too long on that as the man was attacking again, Tim smirked as the man seemed surprised at his fighting techniques. Changing from defense to offence he moved in fast precise movement's one he was taught rigorously over the years to protect himself. Managing to disarm the man so he was now holding the knife he placed a cut on him. The man touched it seeing his own blood he tilted his head before attacking again in fast harsh movements Tim barely had time to defend himself. They crashed through the cubicle's landing on Ellie's desk breaking her computer. Tim bouncing back to his feet to see his opponent doing the same.

"You have something I want Agent McGee." The man said for the first time with a very obvious thick Russian accent.

"Can't say that I do. You shot up my apartment." Tim replied rolling on the balls of his feet ready for the man's next move. "You know I think I would like to know the name of the man that is trying to kill me. It seems only fair seeming you know mine." Tim said barley getting out of the way of his next rapid attack. He seemed to have another knife in his hand.

"I will get what I want." He said as they once again were preoccupied attacking each other as the other defended themselves. "You fight better than I thought…You are different then what I was led to believe." He said once again as they circled each other.

"Anyone tell you, that you talk too much." Tim smirked as the man frowned they both heard running feet and before Tim could turn to see who it was the man charged at him and they both went through the window falling the two stories landing on the Directors car smashing it. Tim groaned breathing deeply.

"That hurt…let's not do that again." He said rolling off the car in time missed the blade by centimeters. He clumsily blocked the man's attack who seemed perfectly fine after their two story fall. He leaned back in time to miss the blade from his neck but it nicked him. The man jumped back from Tim surprised.

"You are not my Timothy McGee."

"No? What gave it away?" Tim stated as his face seemed to glitch then Sam was standing there in McGee's clothing. She was smirking as his face turned from shock to anger in an instant looking back up at the window he growled as he moved in a blur but Sam was ready for him.

2 hours earlier…

Sam bent down behind Simmons as they scanned agent McGee, she pin pointed some details that need improvement. Bobbie helped out with setting up the Machine that they needed as Natasha stood back and watched. Simmons then turned to Skye as they began talking about programming the necessary adjustments. All in all it took them over an hour and a half to get what they needed ready for what Sam wanted. Sam had left with Gibbs to get McGee's spare clothes, when they returned Bobbie had taken Skye to Abbey and Dalilah who were busy working on trying to locate the man. When she returned Gibbs noted that she was carrying another case but this one he knew held a rifle. He had to admit he was impressed with what he was seeing but didn't let on he stood back with Tony and Ziva who were also looking on with interest.

"Agent DiNozzo why do you keep staring at me." Natasha asked hinting her irritation in her tone.

"Sorry it's just you fought aliens…like real aliens. I can't believe I am meeting an Avenger." He said excitedly only to get a punch from Ziva gaining his attention. "Sorry." He mumbled looking down as they then left heading to Abbey and the others. When everything was ready Tim couldn't believe in fact none of the NCIS agents could believe it as everyone was back in the conference room. Sam was now identical to Tim they were looking at each other.

"How?... You know what I don't want to know." Director Vance stated

"What about his voice? I mean if you were to talk it wouldn't matter how much you look alike you don't sound like him." Tony stated

"Really Tony? I thought you would have seen this on one of you movies." Sam replied but it wasn't Sam's voice it was Tim's voice.

"Damn." Tony stated not quiet believing it. "Now I don't even know what one is which."

"I am." Both Tim's stated but Sam gave it away when she ended up laughing at their reactions.

"Send the text." She told Bobbie who nodded and sent the text to Maria hoping that this part of the plan was false. If Sam was right that would mean someone in SHIELD was compromised and that was never a fun thing to learn. "Alright positions." Sam said when they got Maria's reply so everyone went off to their assigned area's now seeing what the SHIELD agent accomplished they found themselves having a little more faith in the plan. Only Ellie seemed to be slightly reserved and Sam tried to give her a reassuring smile but even she knew it seemed weird coming from McGee's face.

10 minutes later Sam left Tim in Natasha's capable hands before walking out of the room heading for the elevator.

BACK To Present…

Sam dodge another swipe of the blade feeling it run through her sleeve of the suit she managed to grab the knife again stepping back looking at the tear in the suit.

"Hey this was borrowed." She frowned as she threw the knife at him which he easily dodged but it did what she wanted so she once again went on the offence.

They were a blur of punches, kicks and parries they both ended up on the ground wrestling she could tell this man was beyond pissed that he was on auto attack which was dangerous Sam knew... He ended up on top of her choking her but she had him trapped in a thigh hold, one she was taught from Romanoff and that she had performed several times efficiently in the past. This time was differed he was nearly as good as her in his techniques. He lifted her up and dropped her on the ground hard at the same time as never releasing his grip on her throat.

Sam felt her grip weaken ever so slightly at the same time he did he was grinning now. That was when she grabbed one of his secret knives 'seriously how did he get this many weapons through security?' she thought as she stabbed him in the ribs grunting when the pressure on her throat relaxed enough for her to get oxygen. She knew it was no serious wound and he was once again on the attack but this time she wouldn't let him get her in that positon again she flipped him before jumping up and away from him regaining her breath. He was already up…

"I was going to kill you for interfering but it was good you did. You have something I want." He said and Sam hesitated she knew what he was talking about but was confused how he knew.

"You can sense it?" Sam asked

"I want it." He said moving in on her again more savagely than before like he now had a purpose instead of hatred he seemed calm and she knew this was far more dangerous than simple rage. She was now fighting for her life.

AN: WOW…What do you think? Is Sam going to be alright? What secret is she hiding? Where are the others? Until Next time.
