"So you don't know about the Stargate Program?" said Rodney.

"The what?" The whole NCIS team said.

NCISxSGAxNCISxSGA

After a lengthy discussion on Stargates, Wormholes, the Ancients, the Wraith and Atlantis, the NCIS team was debriefed, but were still skeptical about this.

"I mean life sucking aliens and going to other planets instantly and the lost city of Atlantis. I'm sorry, but it sounds like just a joke to me" said Tony clearly thinking that they were making fun of him.

"Hmm, I might just have something..." Rodney trailed off thoughtfully and he fished something from his pocket from his jeans. It was a pretty little object.

What is that doing from the SGC! asked a very angry Shepperd. "You know the protocols" I know the protocols! Well I just wanted to experiment with it. To see what was it."

"You have a lab and scientists to do it."

"Don't trust them!" singed-songed Rodney

"Whatever. It's your job you're losing" John rolled his eyes, frustrated at the Canadian.

"Here! catch!" Rodney unexpectedly threw the object. That was a first, throwing an invaluable piece of technology. Shepperd caught it deftly. It was a little round ball. With dents just like the jumper.

As John catched it, it lit in his hand. It opened at the seams and activated what was inside. Hovering just above his hand, was a hologram of the beautiful woman that they encountered in the hologram room in Atlantis. It started to talk.

"In an effort to save the last of our kind, we submerged our great city into the ocean. The Atlantis Stargate was the one and only link back to Earth from this galaxy, and those who remained used it to return to that world that was once home. There, the last survivors of Atlantis lived out the remainder of their lives. This city was left to slumber, in the hope that our kind would one day return."

"Hmm, a portable hologram"

"Cool!" said DiNozzo. John tossed the hologram to Tony, turning off, as it left his hand. Tony dropped the sphere as he tried to catch it.

"Hey! Be careful with it" warned Rodney. "It's a valuable piece of equipment!"

"Talk for yourself" retorted Tony bending over, picking the hologram projector from the floor

Unfortunately for Tony it didn't lit up for him. Neither for Gibbs and Ziva. But by surprise, it lit up for Tim.

"Hey! No fair!" whined Tony. "Why does it work for him and not for me?"

"You have the ATA gene" said Rodney surprised. "And I think a little less than the Colonel"

The question was on the tip of their tongue for the people who didn't do Gate travel for a living.

"Right, right." Rodney caught the stares directed to him and his team.

The ATA gene or The AncientTechnology Activation is a gene that certain people, like the Colonel, possess from the Ancients. Shepperd her,e got the strongest ATA gene, Well, except for Gen. O'Neill." He didn't elaborate further.

Just then the phone on Jenny's desk started to ring. She stood up from the couch, crossed the room to her desk and answered it.

"Yes?"

"Ok"

"We will be right down, Ducky."

"Ducky?" said Ronon, thinking it was strange to have a animal as a name

"Dr. Donald Mallard, our Coroner."

"Oh"

"Going down are we?" John stood up stretching a bit to loosen his muscles after sitting for so long. "So led away"

So the little-big group was led by Gibbs, for the sole purpose to see what happened to the dead marine. They trooped out the office down the stairs, first making a stop to the bullpen to leave the AT-1 stuff before going to the elevator. It took two trips to go down because they were so much. No more than 5 people on this elevator. We wouldn't want the elevator to break down.

So they entered Ducky's lair.

"So our Sergent Lewis Green was tortured then murdered" said Ducky peeling off his medical gear thinking that Gibbs was there.

Rodney sneezed as the smell hit him when he entered the autopsy lab. Ducky turned quickly, tensing when he heard it. But visibly relaxed when he saw Gibbs.

"Well aren't you going to present them?" indicating the AT-1 team clustered together.

The scruffy haired man stepped forward and and presented himself and his team as if he did it many times.

"I'm Lt. Col. John Shepperd. This is Dr. Rodney McKay" The man who sneezed looked up and nodded. Teyla Emmegen. She nodded too "And Ronon Dex." The man who looked like if he was from Hawaii, gazed at him. "And This is my marine." As he looked sadly towards the body.

"I'm so sorry." said Jenny from beside him

"The was a good man."

"So you said he was tortured?" Gibbs trying to change subject.

"Yes. Multiple 2nd degree burns. But that's not all he has a broken fibula and tibia. And two gunshot wounds to the head."

Ducky saw the Scientist wince.

"Ouch! That must of hurt!"

"I don't think that he would had felt anything. Except for the broken bones."mused John

"So anything else?"

"Nope, but there is this interesting mark on his chest."

"Can I see it?" asked John

"Sure, if you want to."

Ducky and John went over and looked at the chest of the body.

"It's a feeding mark" announce John. "Looks pretty recent"

Wait? It can not be. He was not even fed on when he was off...on mission" piped Teyla remembering the doctor didn't know about the team.

"Oh! No! It means that there's a Wraith on Earth!" exclaimed Rodney.

Whoops! Long time! Sorry. School and such I didn't know what to write. Promise to bring out the next chapter real soon.

Um also, the hologram that talking is a piece of the transcript from gateworld. Don't belongs to me. So please don't sue me!
