Stargate Atlantis & SG-1 / Portal 2
Summary: Cave Johnson of Aperture Science becomes the leader of Atlantis after the IOA and UN pull the SGC's funding away. How will everyone cope with their new enthusiastic, insane, caution-less leader?
Note: In this cross over I'm making Rodney related to Cave Johnson. Caroline and Cave Johnson had Chell Johnson, who with a McKay had Jeannie and Rodney McKay.

General Landry sat down at the conference table annoyed. He had just gotten off long numerous phone calls with the President, representatives of the UN and the IOA. General O'neil leaned back in his chair and looked to Landry. "That bad?"
Landry sighed. "Their pulling their funding." Jack shrugged. "They always say that. They never actually do it."
Landry shook his head. "I don't think their kidding this time, Jack."
SG-1 walked in.
Cameron looked between Jack and Landry. "Sir's?" Landry looked at them. "Funding for the SGC's operations are going down hill." Jack crossed his arms. "What are they whinny about this time?"
"The IOA believe there's not enough things coming out of the gate worth the money their putting in." Landy replied.
Daniel put his two cents in. "But where always finding new cultures to study and bring back priceless artefacts!"
Jack leaned over to Daniel. "I think their talking about things actually worth something Daniel."
Daniel replied sarcastically. "Like big guns and spaceships."
Jack pointed at him. "Exactly! Lets find stuff like that!"
Daniel rolled his eyes. Cameron slapped his hands on the table. "No. This isn't gonna happen."
"It already has. They've given the order to return all remaining teams off world then their shutting it down the gate." Landry replied.
Cameron shook his head. "Nope. This has happened in the past already. Something always happens to change their mind where going to be fine." He replied decisively.
"Indeed." Teal'c agreed.
"If they actually go through with this Sir, what about Atlantis?" Asked Sam.
"I don't know. I doubt we could force them home, or have them bring Atlantis here." General Landry replied.

A few days later Woolsey had been briefed on the situation on Earth. He had informed the staff and he had accepted his return to Earth.
Everyone else though obviously refused and decided to let Earth figure themselves out, refusing to pack and leave when ordered. However, once Woolsey had actually packed his things and walked out the gate it all felt real.
The Military had at that point turned to Colonel John Sheppard and the civilian's to Dr. Rodney McKay to fix the situation now that they where the highest ranking members left without a leader.

"Ya' know. We could just stay here. Not like their gonna make the effort to come her and drag us out." Sheppard shrugged.
"Well they could but yes, yes, highly doubtful. Not like they could ever make me leave my city. My city needs me." McKay replied and held up a finger.
"However, it could get very, very bad without their support. He added.
"Rodney, we've been on our own before we don't need them as much as you think. Besides how much help have they really ever gave us with the Wraith anyway?" John replied.
Ronon had his arms crossed. He grunted. "I was on my own for years against the Wraith. I know we don't need anyone."
Rodney frown. "Well did it ever occur to you both that without Earth's support we will eventually run out of ammo? Let alone coffee?! How are we going to fight them then, hmmm? You need bullets and I need my share of coffee!"
"We do have our trading partners." Teyla added trying to be helpful.
"Teyla, most of your trading Friends are only good for food. How many of them would actually be willing to share ammunition when they need that too for their own defence of the Wraith?" Rodney reasoned.
"What about the people who want to keep in contact with their families on Earth?" Dr. Beckett put in. "I got a Mother to keep an eye on. Cant have her worried about me bless her heart."
Sheppard's eyes where shifting in thought while he realized the possible implications. "McKay will think of something."
McKay raised an eyebrow. "I will?"
"Don't you always say you can find a solution to the impossible?" Sheppard pointed out.
Rodney lifted his chin. "Well yes-"
"Good." Sheppard lifted himself from his chair, cutting Rodney off. "Then you'll think of something."
McKay was going to complain but before he could the others where already getting up from their seats.
Teyla put a hand on Rodney's arm. "We have faith in you."
Beckett nodded his head. "Ie, good luck lad."
They left and McKay sighed and grabbed his laptop. "Why is it always me?"
