Chapter 1

Colonel Jack O'Neill stood in green battle dress with full battle gear and his hand grasping the P-90 rifle as he looked upon a large oval shaped mirror. It looked different than the one they found before. It was elegant and seated in a golden frame. He glanced at his team and asked, "Is this what I think it is?"

"Let's not play with it Jack," Daniel warned as he realized it was indeed a quantum mirror.

Sam sighed, "Hammond ordered the other one destroyed. This is an opportunity to study it further."

"We're not taking this back, Carter." Jack determined. "It's too dangerous."

"Let me get some basic readings from it before we blow it up," she miffed annoyed. She knew that was the next and hated the idea of destroying such advancement. She went behind the mirror and found the access panel. "This will take time, sir." she spoke as she worked.

"Just hurry it up," Jack grumbled. He wanted it destroyed it before yet another version of Sam or worse…Himself were to come through.

Teal'c stood and simply observed the dank area. It was dark and gloomy. The mirror seemed to have been hidden to his estimation for no one in their right mind would wander into such a depressing place.

Sam reported, "I just detected a power spike." She went to unhook her computer when they noticed they were no longer in the dark and gloomy room. Instead they were in some sort of warehouse. A man in a suit lay bloody and tied on the floor before them. Surrounding them were men and women in black uniforms with a skull and crossbones insignia.

Jack huffed, "Send us back!"

Sam gasped at the situation.

"It works!" a tall gray haired man with a colonel's rank sporting the black uniform with the skull and crossbones insignia shouted.

The man in the suit looked up with pleading eyes as the tall colonel aimed a Lugar pistol at his head.

Instinctively, Jack opened fire to save the man and not before long a firefight erupted. The mirror was hit with a few bullet holes as Sam found cover. Daniel managed to grab the hogtied man and pull him behind to safety. As Jack, Teal'c and Sam took on a dozen black clad soldiers Daniel untied the gag on the man's mouth. He asked, "Are you okay?"

"I am," he replied. "Untie me."

Daniel untied his hands and asked, "Who are you?"

"I'm SHIELD agent Phil Coulson." he replied. "Hydra was gonna kill me. You just saved my life. Who are you?"

"I'm Dr. Daniel Jackson." he told him.

Phil untied his shoes and looked for a pistol, "We need to get the Avengers."

"Who?" asked Daniel.

"The Avengers," he repeated. "That mirror is from…" he cocked his head. "I just saw you come through it."

"Yeah," he nodded.

Jack huffed, "Daniel! We're leaving!" With the mirror damaged by the bullet holes it was impossible to return at that time. He made a call to retreat.

"Where are you from?" Phil asked.

"Earth," he told him, "From another reality. We need to get out of here."

"You have a radio?" he asked.

Daniel nodded, "Walkie talkie."

"Give it," he held out a hand.

Daniel handed him his radio and watched as Phil changed the channel and then sent out Morse code.

Phil handed him back the radio, "We get the shore and we have a ride."

"Shore?" he asked.

"We're on an island." he informed.

Daniel asked, "We on Earth?"

Phil asked, "You weren't on Earth?" He then noticed the patch, "What is SG-1?"

"I take it you don't have a Gate," he sighed.

Phil had no idea what a Gate was but asked, "Can I borrow your pistol?"

With a gunfight raging around them Daniel decided they could use the help and handed him the 9mm he carried.

Phil glanced at the gun, "Nice Beretta." He then opened fire directly behind Daniel killed a Hydra agent who was about to shoot him in the back.

Daniel looked behind him and figured Phil just saved his life in return. "Thanks for that," he told him.

Phil sprang to his feet with pistol in hand, "We need to get to the surface."

Jack asked, "You know how to get us out of here?"

"I do," he told him.

"Lead the way," he shouted.

With SG-1 backing Agent Coulson he led them out of the private fortress and to the nearby shore. It was night time and visibility was limited. A large and futuristic looking helicopter dropped from the dark skies above and the loading ramp lowered from underneath. Phil led them inside the helicopter.

A redheaded woman in black leather co-piloted the bird beside a dark haired and blue eyed man. She turned around in her seat, "You see it, Phil?"

"It's there," he nodded. "These four came through it. Hydra caught me. They saved my life."

Natasha stated, "Get us out of here, Clint."

He gave a nod and closed the loading ramp. The chopper took straight up and disappeared in the darkness.

Natasha Romanoff looked at the four and asked, "Who are you?"

Jack asked, "Who are you?"

"I asked you first," she smirked back.

"I'm Colonel Jonathan O'Neill, US Air Force." he told her.

"Is the Air Force after the mirror?" she asked him.

"Nope," he shook his head. "We stumbled upon it and was gonna blow it up with it activated and now we are here."

Natasha wasn't sure she followed what he was talking about. "Do you know what the mirror does?"

Jack looked to his Major, "Sam can explain it to ya."

Natasha looked to Sam.

"It opens a doorway to other realities," she told her. "We just slipped from our reality into yours. The mirror was damaged in the firefight. I will need to repair it to send us back home."

She asked, "Where is home for you?"

"Place called Colorado Springs." she told her.

Clint stated, "That's NORAD!"

Jack grinned, "Great! You have a NORAD too!"

Natasha asked, "What do you mean from another reality?"

Sam explained, "Multi-universe reality theory states that you can have multiple realities all existing in the same place. The realities can be identical or very different. We appeared to have slipped into a reality that is different from ours. Who were those men with skull and crossbones?"

"That's Hydra," she told her.

"Are they dangerous?" she questioned.

"Very," she nodded. She spotted Teal'c and asked, "What's that thing on his forehead for?"

"It the symbol of an enslavement to a false god," he frankly stated.

"Is that…" she squinted, "burned into your head?"

"Indeed," he replied.

"You don't sound like you are from around here." she noted. "What's your nationality?"

"I am Jaffa," he reported.

Natasha had no idea what a Jaffa was much less where a Jaffa was from. "I never heard of such a nationality."

Phil asked Jack, "When you found the mirror where were you?"

"Off world," Jack admitted.

"That's why you said you were from Earth," he looked at Daniel.

"You don't have to be on the same planet to cross realities. You cross to wherever the quantum mirror brings you." Sam informed. "We were off world when found our mirror. It activated and connected to your mirror. That mirror has been damaged and is the hands of some dangerous men. This really isn't a good situation."

Phil told her, "This mirror is from another planet. It's called the Mirror of Odin here. Sounds like you know more about it than we do. I was sent in to figure out what it was and I was caught. We don't know what we are dealing with. Do you know how to repair this mirror?"

Sam pondered, "Depends on how damaged it is."

"Carter can fix it," Jack insisted. "Just help us get the mirror and we will go home and get out of your hair."

"You're name is Carter?" Phil asked and then spotted the name badge.

"I'm Major Samantha Carter," she nodded.

"Any relation to Peggy Carter?" he wondered.

She recalled, "I had a great aunt named Peggy. She was a WAC in World War Two."

Clint stated, "Our Peggy was a WAC in World War Two."

Curiously Phil asked Sam, "What happened to your aunt?"

"She married a pilot, he died during the war and she never remarried after that," she stated. "She passed away a few years back of old age."

"Ours is still alive," he informed. "Have a seat SG-1." he motioned for them to sit down.

Jack asked, "Not gonna disarm us and send us to a cell?"

"SHIELD could use you," he figured. "We need to get that mirror back and you need to go home. I think maybe we can make a deal."

"Which is?" he asked.

"You join SHIELD and help us get the mirror. We will help you return." he suggested.

"What is SHIELD?" asked Jack.

"Strategic Hazard Intervention Espionage Logistics Directorate," he told him.

Jack huffed, "What? What do you people do?"

"We protect Earth from alien invasions and other dangers." he smiled. "What does SG-1 stand for?"

"Star Gate One," he told him. "I like ours better."

"You have a SHIELD?" he asked confused.

"We do," he gave a nod. "It's called the SGC…Star Gate Command…Easy and simple to remember."

Phil stated, "I'll have to remember that." He smiled at his new find. He instantly liked Jack and his crankiness. He found Sam to be very smart and attractive. Daniel was helpful and Teal'c seemed strong and steady. Phil was a very good judge of character and he had a very good feeling about SG-1.
