Spoilers for SG1 Episodes: Point of View and Ripple Effect and SGA: McKay and Mrs Miller.

A/N: I am the one who was pissed that Dwparsnip created such a sad universe for one of the Rodneys in McKay Plus Four so I'm adding to it. (With DWP's permission of course!)

You need to read McKay Plus Four, all three chapters, to make sense of this so go read it if you haven't. Awesome writing. It moved me to tag it!

No beta so all mistakes are mine (well, quick reads by dwparsnip and koinekid-thanks!). Also, I haven't done a ton of research on alternate universes, so sorry if my science is sloppy.

"We've picked up a signal from the Daedalus," Major Marks stated from his position at the con. "It's banged up pretty bad, ma'am."

"Colonel Lorne, this is the Colonel Carter, do you copy?"

Static filled the room as Sam's eyes met Rodney's for a second. They both feared that the ship might have been lost during its last skirmish with the Replicators. "Rodney…" Sam started.

"I'm on it," he replied. "Trying to boost the receiver."

"Sun… Lorne… Heavy casualties…" a voice broke through the static.

"Can you clean it up?" Carter asked McKay.

"Working on it," Rodney stated as his fingers flew over the console.

"Strange energy read…. Picked up (static)…. Doctor Kusanagi ensures us she's not a Replicator. And I'll tell you she came in handy with all the injuries we had. We lost Doctor Cole when we took a hard hit … and we're still venting atmosphere," Colonel Lorne explained.

"Colonel, do you want us to beam out your crew?" Sam asked. "We'll be in range in a couple of minutes."

"If you can. Doctor Kusanagi thinks if we shut off life support to most of the ship, we'll be able to make it to Atlantis," Lorne answered.

"Great. Now what did you say about a visitor?" Carter asked.

"Doctor?" Lorne was talking to someone on his bridge.

"There was a huge power spike like the one when that rift in space-time appeared several years ago," the quiet voice of Miko Kusanagi came over the comm.

Rodney looked at Sam with guilt in his eyes, as that was one of his failed experiments.

"And then she suddenly raced into the infirmary in the midst of the attack. From what little time I've had to question her, it appears Doctors McKay and Zelenka in her universe were trying to develop a drive to move ships between parallel dimensions. Things started to unravel and the crew of the Daedalus had to be beamed to a nearby planet. She somehow got transported here instead."

"Who?" Rodney asked.

"We didn't hear her name," Sam clarified.

"Doctor Jennifer Keller."

A look of absolute horror crossed Rodney's face. Two Jennifers? His eyes connected with Sam who knew far too well the dangers of having two of the same person in the same universe.

"Beam her to my ready room," Sam said as she got out of her seat.

"I better go…" Rodney started heading in the opposite direction.

"Rodney, I need you with me," Sam ordered.

He nodded reluctantly and followed his CO. Tons of emotions flowed through his brain but the one at the top was a pain he couldn't brush aside. I really hope this one isn't married to Ronon.

Jen Keller couldn't stop shaking. The events of the last forty-eight hours shook the usually calm, collected Midwesterner to the core. Never in her life had she faced as many trials.

First, the experiment on the Daedalus in her universe went awry forcing the evacuation of the crew as the ship shook and began to lose power. The physician ran to her quarters to grab her pack of personal effects and was beamed out of the corridor because the ship was starting to break apart. Instead of going to a planet however, she ended up in a corridor on the Daedalus once again. Explosions were wracking this one too and knocked her off her feet.

Jen raced to the infirmary, clutching her backpack, and calling Colonel Caldwell on her earwig, but only received static in return. Once she arrived, a frightened nurse that she didn't recognize cried out that the CMO had been killed and immediately pressed Jen into service. But I'm the CMO of the Daedalus, she thought.

After dealing with more burns, broken limbs and cuts that she had in her entire medical career to date, she passed out on a bed for a few minutes before talking to the command staff, Colonel Evan Lorne was the commander and Doctor Miko Kusanagi was the head of engineering. When she asked about Colonel Caldwell or Doctor Novak, she got sad faces stating they hadn't survived an assault by the Replicators almost four years ago. From then on the conversation spiraled out of control, leaving her dizzy and with a splitting headache.

Dr. Kusanagi deduced that Jen somehow came into contact with the rift in space-time being formed by the experiment while she was in the Asgard beam.

"So I sh-showed up on a Daedalus in a-another reality?" Jen asked with chills running up and down her spine. A report from long ago came to mind about an incident involving SG1 and Samantha Carter. Entropic cascade failure results in the death of the subject from the alternate reality. A wave of panic flashed through her, begging her to run, but she remained frozen on the spot.

"Yes," Colonel Lorne stated.

"And in this reality I'm not the CMO of the Daedalus?" she asked.

"No, that was Doctor Cole," the Colonel stated.

"Who is on Atlantis with Doctor Beckett in my reality. She's his second-in-command." Jen gripped the gurney harder and tried to remain upright, exhaustion and terror as death loomed even closer threatened to overwhelm her.

"Doctor Beckett is alive in your reality?" Miko asked.

"Of course," Jen explained.

The sudden sounding of klaxons alerted them to another attack from the enemy called Replicators, which Jen had never heard of before, and sent them scrambling to their stations. More injuries flooded the infirmary and left her too busy to talk before the Sun Tzu arrived.

Jen wasn't sure if she was being rescued or interrogated when she was told that she'd beam directly to Colonel Carter's ready room. At least she might be able to help me. She was almost as smart as Doctor McKay in my reality.

Once Jen rematerialized in a small room and caught two sets of blue eyes looking at her with shock and sadness, she knew her life was almost over. It's only a matter of time before you die because there are now two of you in this reality.

"Doctor Keller?" Sam emphasized her last name.

"Yes," she replied as she looked at the man next to Colonel Carter.

Doctor Rodney McKay stepped forward with a wary smile on his face and concern in his eyes. The concern was something she never saw from the Rodney McKay in her universe and it was the final thing to push her over the edge.

As darkness descended over her vision and she fell forward, she heard a shout of Jennifer from Rodney and felt his arms wrap around her to keep her from hitting the deck.

Thanks again, dwparsnip, for letting me play in your universe.
