After creating what McKay reluctantly agreed to call 'Miller's Crossing', Radek sent a probe via the interdimensional bridge and all present watched the monitor screen as they held the crossing open to see what was on the other side. Jeannie stood in between McKay and Radek, and gaped in surprise, along with everyone else on seeing an alternate version of herself on screen with shorter hair. McKay spoke into the microphone,

"Hello? Who is this?"

The other Jeannie replied, "I'm Doctor Jeannie McKay of the Earth Colony Atlantis… who are you? You sound like my annoying brother Meredith."

Everyone this side snickered before McKay glared at them into stopping.

Jeannie, surprised, spoke into the microphone, "Hello? Doctor McKay? I'm Doctor Jeannie Miller, speaking from Atlantis… our Atlantis. We're conducting an experiment to maintain a stable bridge between two universes."

Jeannie McKay replied, "Oh right… you're me, and that must have been Mer. Ok, yes, we ran a similar experiment and grabbed little snatches of energy from several universes at random but…."

McKay interrupted her, saying quickly, "Yes, yes, yes, we did the same thing but it had the nasty little side effect of destroying other universes."

"Well Mer, that certainly beats destroying a solar system."

As everyone glanced at McKay, he said, "It was two-thirds of a solar system, thank you very much, and it was uninhabited."

Sam smiled and asked, "How have you guys come along?"

Jeannie McKay, surprised, said, "Colonel Jackson?"

Sam blinked in surprise and replied, "Yes?"

"You're pregnant in our universe."

Embarrassed, Sam said as McKay rolled his eyes, "Okaay…"

Jeannie McKay smiled and said, "Ok, well, we scored a ZPM which really got our Mer pissed."

Radek asked, "Just out of curiosity, what is your role there?"

"Hey Radek… I'm the chief scientist."

McKay looked increasingly annoyed as Sam slowly patted him on the shoulder, and he asked, impatient, "Pleasantries aside, how did you do it?"

"We got lucky Mer. Actually, we've got a spare if you're after one. I assume I just throw it through the McKay… um, Miller Crossing?"

"Rolling would be preferred. It is a delicate piece of technology after all…"

"Jeez, relax Mer. Whichever universe it is, you're so highly strung."

"Just send it over."

Sam squeezed his shoulder and remarked, "Say 'please' McKay…"

As Jeannie McKay sent someone to retrieve their spare ZPM, Jeannie asked, "Um, how come you kept your name?"

Jeannie McKay smiled and replied, "Well, seeing as I'm not married, why would I change it?"

Everyone blinked in surprise, not least Jeannie, and she asked, "You didn't meet Caleb?"

"Oh, I did, and we dated a few times but my work took precedence. I take it you married him?"

McKay remarked, "I'll say… I've got a niece."

"Wow… how are universes differ. Mrs Sheppard's going to be pleased – she likes alternate universes like the rest of us like soap operas."

Surprised, Sam asked, "Mrs Sheppard?"

"Yep, that's what we call Teyla. They got married last Spring."

Everyone exchanged odd looks and smiles, and McKay said, "Yeah, well in ours, Captain Kirk got Elizabeth pregnant."

"Wow… him and Doctor O'Neill?"

Just then the ZPM arrived in the large reactor but no-one paid attention as they practically gaped at the screen in total surprise, especially Sam.

--------------------

As McKay and his team installed the spare ZPM from the other universe, Sergeant Muniz called out, "Sensors detect three approaching Wraith hive ships, its weapons powered. ETA is five minutes."

McKay called, panicking, "That's nowhere enough time… we've got to recalibrate the installation sequence… it's a different style of ZPM, like a two-pin plug in a three-pin socket."

Sam, remembering something, ran off to her office and grabbed Merlin's device from a drawer in her desk with her laptop. As Jeannie, Radek and Jennifer followed her, she sprinted into the puddle jumper bay, using a jumper's power source and linking it to the device. Ignoring the sweat on her brow, she furiously typed into her laptop, interfacing the device with the craft as everyone watched with bated breath.

Sheppard, leaning casually against a bay door, asked, "How long is it gonna take?"

"Ooh, I don't know…"

"Ok… will it work?"

"I don't know."

As Jeannie gulped, Sam added, "We'll know soon enough though."

Sheppard said, "Let me and Lorne take a couple of Jumpers to hold them off with a couple of drone weapons."

"It's way too risky."

"And this isn't?!"

Sam snapped, still typing, "Look Shep, if you want something to do, go and join Ronon in looking at McKay and his team meaningfully. If I send you out in a Jumper, you'll get blown up. There's no time to put out a distress call to the Daedalus… they're ferrying the Athosians to a new homeworld after the earthquake. This and the ZPM are our only hopes."

"Right."

Sheppard fell silent as they all watched her, McKay joining them. Sam finally closed her eyes and pressed a button, whispering,

"It was nice knowing you guys."

They all waited with bated breath, and Sam called into her headset, "Muniz?"

There was a pause before they all gazed around each other in surprise on seeing energy weapon blasts running straight through them. Muniz replied, obviously surprised,

"Enemy has discharged weapons… weapons discharge has… it's passed through us. Enemy ships are moving away."

Everyone cheered, hi-fiving a much relieved Sam, and Sheppard leant down to hug her. McKay rushed off to shout at his team, and Jeannie asked, looking at Merlin's device,

"What is that?"

Sam replied with a smile, wiping her brow with a tissue, "That, Mrs Miller, is Merlin's device. It's shifted us into another dimension, hence the weapons fire going straight through us."

Jennifer knelt down next to Sam and hugged her, whispering, "I knew you'd do it."

"Thanks Jennifer."

Just then, they all felt their surroundings sink, and Muniz called into Sam's headset, "Ma'am, Doctor McKay's team did it. The city's submerged."
