Title: Chain of Events

Summery: There are things that we all want to change in the past. To make so it never happens or to get a different outcomes. But what consequences could occur from changing the past. Could things get better or could they get much worse. Must you sacrifice a life to save another? Are you willing to lose a friend in order to save the other? One NCIS special agent will find out that some events shouldn't be changed.

Spoilers: Only if you haven't seen 'Twilight' and 'Kill Ari'

Disclaimer: I don't own NCIS or any of its characters. (Which might be a good thing to some people) and in no way am I making money off this. Every one else not part of NCIS that's in the story is mine.

A/N: OMFG. Choosing the perfect main character for this story was so hard. It took me days to figure out who to use. The most obvious choices are Gibbs, Tony, and McGee. I thought of the ways the story could work with each of them. Finally after careful consideration I chose McGee. Why? Because to me, it made the most sense, though you might say otherwise. After reading this some of you might agree with my choice, but I know that there's gonna be a lot of people who would have chosen either Gibbs or Tony. But either way please read and review my story. I kinda went a little fast writing this because I'm just trying to get past some of my smaller ideas so I can start on my next big story, but hopefully it will still be good, as long as you get the message. Like some of my other stories, I felt like writing the whole story first then posting it all at once. Why? I don't know. I just do. And just to let you know, it's been awhile since I've seen Twilight and Kill Ari, so I'm real sorry if I mess up any info. Anyways please read and review. I really hope you like it.


Chain of Events

Chapter 1

Ari looked through his scope to see Gibbs and his team in his sight. He put Gibbs in the crosshairs and placed his finger on the trigger. He suddenly changed his mind and aimed at Kate. Kate was oblivious of the looming danger as she stood next to Gibbs scanning the buildings. Suddenly she heard a scream behind her.

"KATE!"

As Kate turned around the last thing she saw was McGee tackling her. Just before she hit the ground there was a loud bang that echoed in the air.

Before Kate could react, McGee got up, grabbed her by the arm and pulled her to cover behind a wall.

"What just happened," Kate asked still a little confused.

"There was a sniper that was gonna shoot you," McGee told her.

"What?"

"Ari was gonna kill you."

"That bastard. How did you know he was gonna kill me."

"Um, Gut feeling."

"Thank you so much," Kate said hugging McGee.

"Don't mention it."

"Where is he," Gibbs yelled as he ran to where Kate and McGee were.

"Boss, it's Ari," Kate said.

"He's in the building across from us," McGee told him.

"Keep in eye out for him," Gibbs ordered.

Suddenly another loud bang echoed through the buildings.

"We gotta get out of here before he gets us,' Gibbs said, "DiNozzo get over here. DiNozzo?"

When they heard no response the three of them looked over to see Tony lying on his back. Then they noticed the blood that was flowing from behind his head.

"Oh my God, Tony," Kate yelled as she and Gibbs ran towards his lifeless body.

"It's too late, he's dead," Gibbs said, "McGee, call for back up and get that son of a bitch."

McGee stood there staring at Tony's lifeless body with a face of shock.

"McGee," Gibbs shouted.

"No, no," McGee said ignoring what Gibbs said, "This is not how it's suppose to happen."

"What are you talking about," Kate asked.

"This isn't suppose to happen," McGee continued as his hands started to shake. McGee then started to step back. He raised his wrist and pushed a button on his watch.

Suddenly everything around him faded to white. He looked around to see that he has arrived to in small completely white room. On one of the wall was a giant TV monitor surrounded by smaller monitors each projecting a live video feed. On the big monitor was a still image of Gibbs and Kate kneeling next to Tony. In front of McGee was a clear table with a white computer on top. Behind him was a white door with a silver doorknob.

McGee ran up to the computer and started to type furiously.

"Your back," said a voice from behind him.

McGee turned around to see a young man behind him. He was slightly taller than McGee, with short, slicked back black hair and wearing an all white suit and shoes.

"I don't get it Leo," McGee said turning back to the computer, "I saved Kate and got her to safety but Ari then killed Tony. What happen?"

"What'd you expect? For him to take one shot and run off without checking if he hit anything? Now way. He gonna stay there till he's at least hit something."

"I have to go back."

"Like I said earlier, if you change something in the past, it's gonna effect the future and your gonna get a different outcome, though it might not be the one you want. As you just saw. If someone that was suppose to die doesn't then some else has to die in his or her place."

"I know I can stop this. I just got to."

"If you insist."

McGee than typed in the last bit of info into the computer and pushed ENTER. The room then started to disappear and almost as quickly he appeared back on the rooftop.

TBC in the next chapter….
