A/N; So okay I've had this idea going round my head for ages and I just couldn't get it out, so like all good little fan fiction bunnies I decided to give in to the itch and put it to paper, or well computer screen…err…whatever…This is a crossover with Star gate SG1 set series 4 directly after window of opportunity. It's a little Au and I'm going to be playing with time lines in the star gate universe but bear with me guys, it'll work (crosses fingers, and hides before fans can throw harmful objects). I'm going to try my hardest to keep in character for Jack and the SG1 guys, and I'm really looking forward to it. But so you know, there will be no Jack/Sam pairing in this, because that is so many levels of wrong its…..well its wrong. Its so wrong its wronger than a wrong thing can be!! Well it is for me anyways. It will be a Jack/Danny pairing, so you have been warned, however there will be no intimate details of the pairs sex life, maybe just the odd kiss and grope now and again. Anyways without further ado, on with the show. Cue music, amazing video footage …you get the idea……lol……..Guess I should add that supernatural wise this is pre-series….I swear that's the last. Now away with you, read the story………………………

Semper Fi. ( Always Faithful.)

Jack O'Neill entered his home threw his bag in the hall closet and sighed deeply. The last mission had been a doozy . For more than 3 months he and Teal'c had been forced to re-live the same day over, and over, and over again. Did he mention over and over? Not only that but they'd had to convince the General and the rest of Sg-1 that not only were they not crazy, or possessed by any alien but that they really were reliving the same day.

They'd finally convinced the General to allow them to travel back through the gate to P4X-639 after countless visits to Doctor Fraiser and her ruthless use of her dreaded pen torch light. It had taken countless times of them returning to the planet before Jack could convince Malikai that the machine he was trying to get to work was not the solution to stopping the pain he felt from losing his wife. Going back in time to spend even a small amount of time with her before she died would not stop the event from happening, nor fill the hole it left you with when they did die. The distraught man had asked how Jack would know how it felt and in a moment of empathy Jack had shouted that he had lost his son, that no matter how desperate he would be to see Charlie again. To hold him. To play ball with his beautiful wonderful son, he just couldn't go through that pain again. It had nearly killed him the first time, and if it hadn't been for Daniel, it would have done. Of course the latter part was left unsaid.

But the mission itself had left him exhausted. His emotions that he kept so under control had bubbled to the surface and he was drained, it would take him a couple of days to reel them back in, put them back in the little box he kept tightly sealed at the back of his mind. The General had awarded the team with a couple of weeks downtime and barring any unforeseen end of the world situations he was going to take full advantage, maybe go to the cabin and get some fishing in.

Carter had gone to visit her father on the Tok'ra home world, it would seem that the months being stuck on a single day had affected them all as Teal'c had left through the star gate to visit his son Rya'c and old friend and teacher Bra'tac.

The only other remaining member was Daniel and as the archaeologist didn't have any family he was staying earth bound, with Jack. The two were planning to spend some time together, Jack slumped into his easy chair and brought a chilled beer to his lips, another sigh escaping him before he could stop it. So no fishing then. All Daniel would do would be to bitch and moan how boring and pointless fishing was, and why couldn't they do something more interesting. Like a museum.

Jack grinned, sometimes Danny was worse than Sarah ever had been when it came whining. Thinking of Sarah made him think of Charlie again, he felt his eyes sting and wiped a tired hand over them. He missed his son every day, it was getting easier, day by day, but sometimes it was like he'd only just lost him. He reached for the photograph that was by his chair, a ten year old boy was smiling happily at the camera, his green eyes sparkling with mischief, a baseball bat slung over his shoulder and a Boston Redsox cap placed proudly on his head. Jack ran his fingers over the still frame, it had been taken two days before Charlie had shot himself with Jacks own gun,

" You okay?'' Daniel asked him quietly, Jack nodded and placed the photo back in its place

" I'm good. So Doctor Jackson, what you wanna do with your time off? Feed that already enormous brain of yours with yet more useless information?'' Daniel huffed and crossed his arms across his chest

" My mind is not full of useless information Jack, and if I recall my useless information'' he used air quotes at his useless information remark that made Jack hide a grin " Has got your ass out of enough sticky situations'' Daniel shot him a glare, Jack moved towards him hands out in a placating manner, Daniel backed away from him until he felt his back hit the wall, he winced when he caught sight of Jacks smirk. The Colonel leaned forward and rested his hands either side of Daniels head, palms against the wall. He leaned in so he was only inches from the Doctors face, his small gasps brushing against his lips,

" Thought you liked my ass Danny'', Jack grinned when Daniels adams apple bobbed ferociously, he leaned in and captured the younger mans lips, kissing him softly, deepening the kiss when Daniel joined in and moaned softly into his mouth. If you'd asked Jack O'Neill , Colonel in the United States Air Force 6 months ago if he'd be in a relationship with another man, he would probably have knocked the person out. But after wearing the bracelets that Anise had brought , and having the enhanced abilities , and the following mission, something had changed between the two friends. Something deeper had taken them both over and neither had been able to deny it. Now Jack couldn't imagine his life without Daniel in it. They had to be careful, with the N.I.D constantly on their backs, they had to be vigilant and not let on of the development in their relationship. It was hard, but Jack O'Neill never went into anything blindly, and Daniel, well Daniel in Jacks eyes was worth it, he was worth the risk.

" Come on Doc, what about an early night?'' Jack whispered against Daniels ear, Danny shivered and smiled into Jacks neck,

" Sounds good to me Colonel'' , grinning Jack took his hand and the two men went upstairs, Daniel was determined to rid the demons from Jacks mind, and he knew just how he was going to do it. A half hour later Jack couldn't even form a coherent thought, when the pair finally fell asleep, sated and smiling, the only thoughts that were running through Jacks mind were what he would cook for break fast the next morning.

Dean Winchester pulled his black beast of a car outside of the wooden property. Today he was posing as a detective, working the recent bout of homicides that seemed to have struck the area. Of course the local police had thought it was nothing more than random attacks by a satanic cult, but so far six people had lost their lives, and it didn't look like they were any closer to finding the culprit. And it would seem that the attacks weren't going to stop any time soon.

It was a case that Dean usually wouldn't have bothered with, but the symbols that had been branded into the skin of each victim had shown that it was more than the local police could deal with. At best it was a cult, trying to summon a demon, at worst it was a witch working for a demon. Dean hated witches, in his mind anybody who dealt with there own body fluids was just not right, in fact they were down right icky. He gave an embarrassed laugh as the thought entered his head, icky, where in the hell had that come from. Dean Winchester did not use words like icky, that was more Sammy's deal. The grin fell away from Deans face at the thought of his little brother, he'd left for Stanford and his new normal life just over a year ago. Dean had tried calling him, but Sam hadn't taken his calls, always letting his phone go to voice mail. After a while Dean had got the message and stopped calling, he didn't understand why he still couldn't be a part of Sam's life. He didn't share the same feelings his dad with about college. He wanted his brother to be happy. Safe. And if going to college and increasing his incredible geekiness is what Sammy wanted, then that was fine with Dean. But his dad hadn't thought the same way. John had given Sam an ultimatum

" You walk out that door Samuel Winchester, don't even think of coming back!!" he'd shouted, Sam had looked to Dean, his big brother for back up, for him to intervene, to say something. But Dean had stood there dumbstruck. He knew Sam wanted to go to college, but what he hadn't known was that Sam had applied or even been accepted anywhere. To say he was hurt was an understatement, confused a given, but when his dad had told Sam that if he left never to come back, Dean just couldn't seem to make any of his bodily functions to work. Even blinking was an impossibility at that moment in time. Sam had looked hurt for a second, then jutted out his chin in defiance

" Fine" with that said, he'd picked up his bag and left without looking back. It had taken Dean a few seconds to get control over his body, but then he was moving towards the door and his baby brother, he wanted to tell him how proud he was of him, how he hoped he'd be happy, that even though John felt that way he himself didn't. But by the time he'd got outside Sam was nowhere in sight and was refusing to answer his phone. Dean had left messages countless times, but he didn't even know if Sam had received or even listened to them.

He sighed heavily, it had been a long hard year. He was with his dad less and less, going on solo hunts and only meeting up occasionally. In the last seven months Dean had seen his dad twice and even those meetings had been small, that had Dean blinked he would have missed them. Instead he got text messaged co-ordinates to take him to another case. He was tired. Bone weary tired, but he pushed himself onwards, he had to or more people would die. It was his dads last set of co-ordinates that had brought him here to Colorado Springs, it was strange being here. It was like he'd been here before, but in all of his memories he didn't ever re-call his family ever coming to Colorado in any way shape or form. So why were some places familiar? He shook of the thoughts and put his game face on. The last murder had taken place not far from this residence and he was hoping that someone inside had seen 'something' to give him a clue as to what direction to head in. Extracting the fake I.D from the glove compartment Dean climbed out of the impala and moved towards the door, he gave a loud sharp knock and waited.

Jack was pulled from his intense blending of the batter mix from a firm knock at the door, he frowned slightly, wiped his hands and went to see who it was before the knocking woke Daniel. When he got to the door he was surprised to find a young man stood there in a suit, he can't have been more than twenty three, if even that.

" Can I help you?'' Jack asked with a raised brow, the young man flashed his I.D and sent Jack a charming smile,

" Good morning sir, I'm sorry to trouble you so early but I was wondering if I could ask you a few questions''

" What about?'' Jack asked remaining firmly in the doorway, you just couldn't be too with the N.I.D on the loose, they weren't above using officers in there dealings.

" I'm not sure if you're aware sir, but there has been a spate of murders recently, and the last one was quite near to your home. I was hoping that you may have seen something''

" Okay, come on in. Who did you say you were with?'' Jack asked

" I've just transferred from Minnesota P.D. I worked homicide there, when I moved here they put me straight onto this case'' Dean lied, he shifted uncomfortably at the penetrating gaze that the man in front of him was shooting him, he made him feel like he was under inspection, like it was his father watching him, and a part of him, a small part felt like he knew this man, but he'd never seen him before so how could he?

" Take a seat kid'' the man offered " You want a coffee?'' Dean grinned

" Always, coffee is good" the man nodded and went to make Dean a coffee, he came back with a good sized mug and Dean took it gratefully,

" Thanks'' He took out his pad and pen poised he began to talk again " May I take your name sir?''

" Colonel Jack O'Neill, United States air force'' Jack supplied, Dean grinned

" My dad was a marine, thought I recognised a military man'' Jack grinned back

" What's your name kid?'', green eyes lifted and looked to Jacks chocolate brown ones,

" Dean Matthews, sorry sir I thought I'd given you my name already'' Jack shook his hand dismissively in the air,

" Not a problem kid, and please call me Jack''

" Thanks. So. Jack, can you tell me if you've seen anything suspicious? Anyone hanging around, a group of people maybe?'' Jack raised a questioning brow, Dean shrugged

" I want to cover all the bases, call it a hunch but I think that maybe there's only one person involved, but my department thinks it's Satanists''

" And you don't?'' Jack asked, Dean shook his head

" Nah, all indications point to only one person being responsible. Make it a hell of a lot easier if it were a group''

" Why'd you say that?'' Jack asked truly intrigued

" If it's a group, at least one of them gets too big for their boots and runs their mouth off. But if its only one'' Dean shrugged " They're harder to track down, more cautious. Did you see or hear anything?''

" Sorry, only got back from the base last night, been on a mission and didn't get back till late. Not been home for a few days''

" Is there anyone else home? Someone else who may have seen or hears something unusual? No matter how insignificant it may seem, it could be the thing that breaks the case'' Jack nodded

" My partners in bed, I can ask him if you like but I highly doubt it. We work together''

" Could I speak to him at least?'' Jack decided to give the kid before him a break and nodded

" Yeah, sure, I'll go get him. But don't know if he'll know anything more than I do'' Dean shot him a grateful smile. Jack froze, the kid when he smiled looked just like Charlie, but he couldn't be. Charlie was dead, sure they'd be the same age now if Charlie had survived, it made Jacks heart ache with loss,

" Hey man, you okay?'' Dean asked concerned

" Huh?'' Jack asked

" I said you okay?''

" Oh yeah, yeah I'm fine. Thanks. Bad mission just tired is all''

" I hear that'' Jack heard Dean whisper, but he was sure that the comment had not been meant for Jacks ears, so he left it alone and went to ask Danny if he'd be happy to speak to the young detective.

Deans eyes wandered around the room he was waiting in, he was taking in all the medals on display, a low whistle escaped his lips. His dad had been decorated, but had nowhere near as many as Jack O'Neill had. The man could open his own medal shop and still have left overs for his private collection, as his eyes travelled around the room they fell onto a framed photograph of a small boy clutching a baseball bat, it was slung over his shoulder and he was grinning at the camera. The boy looked familiar so Dean moved closer to inspect the picture, as he neared he felt his heart come to a stop in his chest. The boy in the picture. The one smiling as if they hadn't a care in the world, was himself. Dean was looking at a picture of his ten year old self staring back at him.

A barrage of images assaulted his mind, he was in a wide back yard playing catch with a man, the man wasn't John Winchester yet Dean knew in his heart that this man he was playing ball with was his father, the images changed, he was in a closet reaching for a closed box high on a shelf. He opened the box and removed a 9mm weapon. A loud bang brought Dean from his mind and he dropped the frame, it clattered to the floor the glass smashing in the process.

Jack raced down the stairs to confront the young detective, to find him with his fingers fisted tightly in his hair, and his eyes squeezed shut. His face was full of pain, a whimper escaped his lips,

" Dean? Detective? Are you alright?'' Dean felt his knees give way, but the pain that was ripping through his head now was far too much to bare and he welcomed the darkness that over took him.

" Danny!! Get your ass down here and call Janet'' Daniel came to the top of the stairs pulling on a shirt,

" What's happened?'' upon seeing the unconscious man on the floor, Daniel made to move towards him, but was stopped by Jacks glare,

" Now Daniel'' Daniel nodded and moved to the phone, Jack was cushioning Deans head, prying back his eyes to try and check his responses,

" Err….Jack?' Daniel ventured slowly, he decided it was safe to carry on when he received no response " shouldn't we call the paramedics instead of the base?''

" No. Just call Janet and tell her to get here and I mean like yesterday. I can't explain this Danny, but, this kid, there's just something about him. He…'' Jack swallowed past the lump that had formed in his throat " He reminds me of Charlie and…''

" Jack….Charlie's dead'' Daniel said quietly, softly, he didn't want to harm Jacks feelings, Jack shot him a glare that he usually reserved only for the Goa'uld or Senators from Washington whom happened to be called Kinsey. Daniel took a step back and picked up the phone,

" I'm calling her now'' he said quietly to Jack, but Jack wasn't listening, he was studying the young mans now lax face. Observing the freckles that spattered across his face, the jaw line that was sculpted yet strong, the last thing he noticed was a small scar at his hair line. A scar that unless you were up close and personal like this could be easily missed. A scar in the shape of a bullet hole,

" Ch-Charlie?'' Jack stammered out. Could it really be his son? Could this young man who had just collapsed really be his son? Jack didn't know what was going on, but he was determined to find out. With or without the help of the SGC, and if it turned out that it was Charlie, then no place in the universe was going to be safe for the bastards who had stolen him.

A/N; So what do y'all think? Any good? Is it worth continuing? I know time lines are more than a little askew, but I'm taking poetic licence with it all. As for Charlie being raised in Colorado Springs?? I'm not sure where he did grow up so I just made it up. Anywho drop me a line and let me know what ya think….. Laters taters xxxxxx
