Summary: For more than two decades, Cat Grant has been sitting on a story that may transform the world – even more than usual. Now, she brings Kara into the world of a man who may have been the canary in the coal mine when it came to aliens. And the truth that is out there will stun even a visitor from another planet.

Disclaimer: Kara, Cat Grant, Alex, and just about everyone else from Supergirl is the joint property of DC Comics and Greg Berlanti. I don't agree with everything he's done to the characters, but I think much of what he's done is worth doing, and I will try to play by the rules he set. Mulder, Scully, and whoever else I bring into this from the X-Files belong to Chris Carter and the incredible team of writers that worked on the series.

Timeline and Universe:

For Supergirl, the series takes place around season 2, only Cat Grant will never have left Catco, and Kara has just begun her career in journalism. For The X-Files, this takes place around the same time as the revival series, so the timelines shouldn't be that out of sync. Now, for the larger issue.

I realize that the worlds that Fox Mulder and Kara Danvers exist in are completely different places, and if he had to deal with the fact that the President was actually an alien, he'd go nuts. (Though, if you've seen your Darin Morgan episodes, he might have an explanation for that, too.) And I'm not certain how he'd deal with a world where aliens are actually supported by the 24 hour news cycle. That said, there's a lot of common ground between the two worlds than there are differences, so I'm probably going to be making more changes to Supergirl's world.

For now, I will simply say that Mulder and Scully are on Supergirl's Earth. However, Obama is still President, and a lot of the things that were history in our world have happened here. Now Alex Danvers and JonnJonez still work at the DOI, and the alien apocalypse that ended Season 1 happened. As for the conspiracy of the X-Files, well, that's going to be clear as we unravel the mythos.

Ready to stick with me? Then, here we go down the rabbit hole.

Chapter 1

Snapper Carr shook his head. "I can't believe I'm about to say this, but you're really going to go through with this?"

Cat Grant, head of Catco, had known Snapper for more than twenty years. She considered him a close friend, although Snapper mad it a point of pride about not having any. "This can't be any worse from when we split on the issue of superdelegates at the DNC?'

"This isn't the time for banter, Catherine, and I'm not just saying that because I was never good at it." Snapper wasn't going to be deterred.

Cat looked at him. "This is a whole new world we're living in. I knew it was a risk to embrace Supergirl as my own, and that paid off. And this can't be considered any more dangerous than that."

"Supergirl is a hero. No one ever lost money by raising the flag and cheering. This" Snapper shook his head again. "This really could damage everything you've built. Even if you do this perfectly, and I mean from beginning to the end, there is an excellent chance that Catco ends up being regulated from the biggest telecommunication player in the country to something that only the tinfoil hat crowd embraces."

"I'm a businesswoman, Snapper, I'm well aware of the possibility of financial downfall." Cat Grant turned away and looked out at the city. "But I'm also a journalist. And for the last few years, I've basically sat on my hands, knowing full well that there has been a man out there who predicted and foresaw a lot of what's happening. We're not talking broken clock right. We're talking atomic clock right. And I ignored it."

Snapper then actually narrowed his eyes a little, which for him was a sign of great concern. "You're not doing this out of some misplaced sense of guilt, are you?"

"I have guilt, Walter, it's definitely not misplaced." Cat was concerned. She only used Snapper's real first name when she was genuinely worried about something. "He was a prophet. He genuinely saw what was going on. And I regulated him to a trash heap. I know why I did it – even now, I can't fully blame myself for it – but he was right, and I was wrong. I couldn't admit this to Mike Wallace, but I can make it up to him."

Snapper considered this for a moment. "You're sure he's still alive?"

"I've done my homework. He's living on a farm in Newport News. Probably one step away from Ted Kaszynski territory. "

"When are you going to reach out to him?"

"Not until I know for certain that we have all the facts." Cat looked at him. "You're right about all the hits that we're going to take if I put him on camera. Which means, more than ever, that we have to be right. He needs to be more thoroughly vetted than any Supreme Court in the last twenty years, particularly when it comes to his opinions."

Snapper didn't even crack a smile. "I'm still not sure you're right about having the new girl handle this."

"Her name is Kara Danvers. And as many headaches as she's given me over the past year, the fact remains she has a connection to this story that I'd be a fool to deny. She'll go after it with the ferocity of one of those velociraptors. "

"And if the story goes wrong, we'll be accused of putting a rookie on what might be the biggest story since Metropolis," Snapper reminded her.

"Kara is many things – most of which you still can't say on my network – but she is anything but wet behind the ears. Once I point her in the right direction," Cat told him, "she will run this story to ground."

Snapper considered this for a minute. He knew Cat well enough to know that there was cunning even in her most virtuous moves. By putting the most junior reporter on this, she could have cover so that when this story blew up in their face (he couldn't imagine this not happening), it could be written off as the overreach of an overly ambitious neophyte. And even though there were parts of this story he still wanted to follow, he knew that he didn't want to go anywhere near it. He had too many ex-wives he owed alimony to.

"All right," he told her. "I'll send her up."

For a woman who could punch out alien colossus and outrun metahumans, Kara Danvers still felt nervous every time that she went into Cat Grant's office.

It wasn't just that Miss Grant was one of the most (if not the most) powerful women in business today, or that she had spent more than a year running errands and getting coffee for her at the drop of a hat. Nor was it the fact that she had come closer than anyone else in the world as to guessing her alter ego not three months after putting her on the map.

No, what was the most unsettling thing about Cat Grant was still, even after all the things that she had learned about her, something of an idol to her. For all the browbeating and put-downs she had endured, she still saw the woman who had, in little more than a decade, risen from rookie reporter to media titan. It was a rise that even now, could only be described as meteoric, and Kara had outraced more than her share of meteors.

So, even though she knew that Supergirl's role in the world was vitally more important than anything that Kara Danvers was doing right now, part of her still wanted to think that this job – the career in journalism she had just started – was somehow more important. Maybe it was because she felt that she would be doing something for herself, not for the world. There was a certain selfishness in that, she knew, but then again, she thought she was entitled to that. The world had Supergirl. Wasn't Kara entitled to a room of her own?

"You wanted to see me, Miss Grant?" she said, as she opened the door gently.

"We've been through a lot the last year, you and I," Cat Grant told her. "I think you've earned the right to call me Cat."

To say that Kara was floored would've been an understatement. Over the past several months, Cat Grant had acted a lot of the time as if she hadn't even known that Kara had a first name. And the few times she had used it, there had always been a certain level of mockery. And Miss Grant let almost nobody call her Cat. Even the President called her Catherine.

"I told you a couple of weeks ago that I saw a lot of myself in you, Kara," she was saying. "There's a blessing and a curse in that. You know better than most just how hard it is to be a woman trying to climb the corporate ladder. Multiply that by fifty, and you have an idea of just how difficult it was for me making my way in the world."

"I've always admired you. I know that you've been a pioneer. In your own way," she chose her words carefully, "you've been just as big an example as Supergirl."

"But there's always a cost to being where I am," Grant turned around and faced her. "You get started in a career such as this with such idealism. You want to make a difference. You want to shake up the system. You want, to use a particularly dull cliché, to change the world. It's only after you start looking back, that you start to see all the compromises that you have to make in order to get there."

Kara wasn't entirely sure where her mentor was going yet. But considering that Cat Grant rarely talked about her rise to power in anything other than glowing terms, she was glad to listen.

"You were what, 11, in 2003?" Grant asked suddenly.

"Yes."

"Then you would have been in fifth grade around the time Richard Clarke went before Congress." Cat looked towards one of the monitors that were everywhere in her office. "I was just in the process of building my first network. We'd been on the air less than a year, and this veteran CIA officer goes live to the country. 'Your government has failed you. I failed you.' Clarke basically tells America that the greatest attack in our nation's history could've been prevented. Even I had to admit, that was a true profile in courage. We have too few of them."

Kara knew that Grant was coming to a point, even though she had no idea where it was yet.

"I came very close to dying more times than I can count last year," Grant told her. "Now, I've been on military frontlines more than a few times in my life, but I've never counted my mortality as often as I have the last few months. And when you face your mortality, your life may not flash before your eyes, but your mistakes do. Now Oscar Wilde may have said that experience is the name that everybody gives to their mistakes. But they don't go on to consider about what that 'experience' costs everybody else. And certainly one doesn't often get the chance of righting those wrongs. That Kara Danvers, is the main reason I asked you here."

"You want me to help right a wrong?" Kara wasn't sure she followed.

"I want you to help me fix my biggest mistake."

"How big a story is it?"

Grant looked at her again. "Potentially bigger than Supergirl."

Considering who she was speaking to, she felt like she'd taken a blow from someone wearing kryptonite knuckles. And considering who had said it, the magnitude could be considering… well, more powerful than a locomotive. "What's it about?"

"What if I were tell you that nearly fifteen full years before Superman showed up on the radar, there was a man who knew that there were aliens on Earth? That not all of them were friendly, and in fact, a covert portion of our government was conspiring with them to colonize this planet?" Cat told her. "And that this same man didn't work for some fringe element of the Internet or talk radio, but rather for the federal government itself?"

Kara didn't think she was any longer capable of being shocked by anything. Even given with Jonn and Alex had told her over the past year, she had been given the impression that all government activity involving aliens had started the day Clark's alter ego had made his debut in Metropolis. Neither of them was in the interest of hiding anything from her; they had made that very clear when Lucy Lane had shown up. And even the DOA had been a purely defensive measure. This sounded far more insidious. "I would ask how reliable your source is?" she said, taking on the mantle of a reporter.

"That's where things get slippery," Grant admitted. "I never had a reason to doubt my source before that. He'd come through for me on a half dozen occasions before then. But when he first came to me with this intel, I did everything short of laugh him off, and suggest if he'd been wearing a tinfoil hat when he'd heard it. "

"When did he come forward with this information?" Kat asked.

"A little more than a quarter century ago," Grant now looked genuinely ashamed. "I had my own personal Mark Felt. And he wasn't just dropping hints, he was telling me who was getting the money and where the bodies were buried. If Bob and Carl knew about this…" She gathered herself. "But that's why I called you in. It may be several presidential administration too late to break the story, but I can offer the man one hell of a Corrections piece."

"He's still alive?" The way Cat Grant was speaking, Kara had naturally assumed the man was dead.

"He has been out of the Bureau for a long time," Cat told her. "That's right. I did bury the lead. The man in question worked for the FBI for more than fifteen years. I had to do a fair amount of digging in order to even find him."

"Who is he?"

"His name is Fox Mulder, and for nearly a decade, he operated what was probably the only unit in the entire government that had anything to do with the paranormal. He was a pioneer, a trailblazer. And as a reward, he was shunted to the basement of the building, given practically no assistance or acknowledgement from the Agency he worked for, was left for dead so many times you would think he was the lead on a soap opera, and the unit that he worked for is considered a cautionary tale." Grant looked at the wall of screen. "That, Kara, is where you and I are going to come in."

Kara had been delivering Cat Grant's coffee for so longer, she'd nearly forgotten what a great reporter she was. She still knew how to hook the listener. "What are we going to do?"

"You and I are going to get Mulder reinstated in the Bureau. And more importantly, we're going to get the X-Files reopened."
