Disclaimer: I don't own Stargate Atlantis

Note: I started writing something about John, Liz and 'The Storm' but that wasn't going so well so I've put it on hiatus and decided to write a story which I wasn't going to write but decided too. Its an AU story and Kate is my own creation. This implies a pre-existing relationship between McKay and Kate on Earth.

Paring: McKay/OC, Sheppard/Weir

Lab

McKay was working late in his lab on a ZPM found on a recent mission to P3C-264. The power was abnormally strong, must stronger then a regular ZPM should be. He'd been working on it for two days straight and still had no way of figuring out why it was abnormally strong. McKay banged his pen on the table and ran his fingers through his hair.

"Rodney, you need to take a break, you're going burn yourself out"

Rodney turned round and saw his vision of loveliness. She was leaning against the doorframe, her blonde hair tucked behind her ears. Her ocean blue eyes looking at him with love and admiration.

"Remember what happened in Russia, you worked for three days straight and then fainted during your presentation?

"Please don't call it that, I passed out"

Kate continued

"I think those three days were the only ones I actually saw you go more then a few hours without food."

McKay smirked at the memory.

"It's not like I was trying to impress you or anything."

"Though I do remember you calling me 'Major Carter' when you came round"

"Never going to forgive me for that, are you?"

"No"

Kate moved away from the doorway and walked to McKay

"Take a break, I'm lonely."

She sat next to him as he kissed her gently.

"See, was that really so bad?"

McKay smirked before turning back round to the ZPM. Kate sighed and decided to follow suit.

"What's wrong with it, apart form the obvious?"

McKay sighed

"I want too turn it on, but the energy readings are too high. It's not safe."

Kate sighed

"I know nothing about Ancient technology but isn't there anyway to extract some of the energy"

"Oh yes, of course, why didn't I think of that two days ago!"

Kate sighed; she was used to McKay's sarcasm. He'd been working two days straight on the ZPM and it was beginning to take it's toll

"It was just a suggestion."

"Well it was a stupid one."

Kate stood up.

"Fine, you're the big scientist here, no wait you're an asshole"

"Well you finally know the real me, congratulations. Surprised it took you so long, but then again I've always had a thing for dumb blondes, why should I be surprised"

Kate was not going to take that lying down. They'd been on Atlantis for a little over two years and known each other on earth for two years before that but she'd never seen Rodney act like that, sure he'd get snippy at her, but he'd never start a fight with her, sure she'd called him an asshole, but she always called him that.

"You know Rodney…"

Before she could finish the ZPM began to glow and make a low buzzing sound. The two of them turned round as the ZPM exploded

Elizabeth's quarters

John, not leaving her mouth, placed Liz on the bed and began to take off her jacket

John moved his mouth to neck and began kiss her collarbone.

"John, I need to be doing something which isn't…Good God this is good."

John had moved slowly down her body in a surprise attack, which he knew would leave her at his mercy. She knew this too, and she loved it.

John began to take her t-shirt off when they heard and explosion. John moved his mouth from her. The look in her eyes mirroring his own thoughts.

"What was that?"

John rolled off Liz and the two off them moved to the corridor were several other occupants of that corridor had also come out of their rooms. None seemed surprised to see John leave Liz's quarters. Liz went back into her room and picked up her radio.

"Peter, it's Weir. What the hell was that?"

"There was a strange energy build up in McKay's lab before it happened."

Liz looked at John.

"Rodney's in there working on the ZPM."

John took the radio out of Liz's hands

"Call Beckett and the medical team to the lab, possible emergency."

John and Liz shared a look before heading into the direction of the lab.

TBC…

I'll try and finish this tomorrow. I know what's meant to happen. What do you think?
