Author's Note: Yup. Colossus and Multiple Man. Piotr and Jamie. I paired them off as a side plot in A Little Complication and they went down quite well so let's see what I can do with them in their own story.

I have no idea how long this story is going to be, I have a fair few chapters in my head but when I start writing my stories tend to start sprouting limbs so we'll see! I'm gonna start off (like I did in Too Late if any of you have been with me that long!) with a prologue which contains a glimpse into a chapter from much later in the story and then we're gonna go back to the beginning and work back up to the prologue.

Now I'll warn you now – I have the beginning and some of the middle but as usual have no idea how to finish. And I can't promise a happy ending either. Also I can't promise to be as regular in updating as I have been in the past – but I will try my best.

So obviously we'll see Piotr and Jamie but we'll also have appearances from the usual suspects, including John and Bobby (not together though!), some Jinx and Tommy (two OCs of mine) and maybe Abi (an OC). Maybe even Pietro…

Disclaimer: Don't own the x-men but I will stake my claim on the uber-cuteness of Jinx and Tommy and Abi if they pop up!

Sleeping With the Enemy

Prologue

The pause seemed to last forever. Fifty feet under ground, in a dimly lit, stone walled room the two mutants just stared at each other, neither moving, neither talking, both oblivious to the noise that raged somewhere in the background…

A loud crash echoed over the rest of the chaos from somewhere to their side, followed by a pained cry and the sound of shattering – ice shattering. Piotr's eyes widened, his gaze turning instinctively towards the noise although all he saw was the stone wall. Jamie smiled cruelly.

"You should go and help your friend," he said blandly. "Pyro won't lose twice."

Piotr swallowed hard.

"I'm not leaving you."

"Awwwww…" Jamie pulled a mocking, sweet face. "Are you worried about me?"

Piotr bristled, crossing his arms.

"I'm not leaving you unattended," he replied flatly. Jamie scowled, glancing sideways as another loud crash filtered through the wall.

"Being a bit heavy handed aren't you all?" he arched an eyebrow. "I thought you guys were supposed to be the peaceful type?"

Piotr's eyes narrowed.

"One of our kids is dead," he replied tightly. Jamie sighed helplessly.

"I told you – that had nothing to do with us!"

"You're the only one who could hack our security system!"

"I set up your security system!" Jamie threw up his arms in despair. "Why the hell would I bother to do that if we were gonna be the ones breaking into the mansion?"

"So no-one else would get there first."

Jamie shook his head.

"You know I didn't take Tommy!" he replied agitatedly, oblivious now to the distant chaos that still raged in the background. Curling his lip up slightly he held out his arms, wrists together as if offering for them to be tied up. "Fine - take me to your leader and I'll tell them exactly what I was doing when Tommy was kidnapped," the multiplying mutant lowered his arms with a wry smirk as Piotr's head dropped briefly. "But of course we don't want your precious comrades finding out that good old reliable Piotr has been sleeping with the enemy now do we?"

Piotr let out a shaky sigh but his face remained stoic.

"I shall own up to my mistakes," he replied flatly.

Jamie's face fell slightly.

"You reallythink I did it?" the multiplying mutant frowned heavily although there was no hiding the genuine hurt in his bright blue eyes. "You really think that I would be involved in this?"

Piotr took a deep breath.

"What use is an alibi to someone who can be in two places at once?"

Jamie closed his eyes briefly before standing up straight, setting the taller mutant a defiant stare, his shoulders bristling.

"Well, if that's how you feel…"
