"The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass…."

- Revelation 1:1-8

This is about six months after Apocalyptic, no specific place in the timeline for that story, but I'll put this one after My Bloody Valentine since that's what I know of the plotline so far. And everyone should know that we're firmly in the Supernatural-verse, so there won't be any mention of aliens. :)

What Must Come to Pass

Dean startled slightly out of his concentration, or rather what had turned into blank staring at the book in front of him, and let out a sigh as he dug his cell phone out of his jacket, raising it to his ear. "Ya?" he asked.

"This is Special Agent Fox Mulder. Is this Dean?"

Dean's eyebrows rose, glancing to Sam briefly across the library table, who was deep in research of his own. "Ah, yeah. What's going on?"

"I got this number from Bobby. You said to call if anything seemed out of my league."

"That I did," Dean responded. He got a sharp shushing noise from a librarian at the ongoing conversation, and received a glare as well when he looked over to meet her eyes. He gave her a wide, innocent smile, but somehow she was immune to his charms and simply pointed to a sign behind the desk that read No Cell Phones.

"Well, I think I've got something," Mulder spoke as Dean reluctantly got up from his seat. That jarred Sam from his focus and he looked up, a questioning look on his face at who was on the phone. Dean held up one finger to him as he left, tossing another smile to the librarian over his shoulder, this one slightly cockier, as he went out the automatic doors.

"Alright, give it to me," Dean said.

"I'm in central Oklahoma right now. I've been here for a day or so with Scully looking into a large amount of deaths—."

"Define 'a large amount,'" Dean interrupted, leaning against the brick wall of the library.

"Ah…." There was a rustling of papers. "By my count so far we've got…214."

Dean's spine straightened suddenly. "What the Hell?" he asked, eyes wide. "Where are you, exactly?"

"Chandler, Oklahoma."

"Is that the CDC thing I heard about? I thought there had only been like five deaths and it was from swine flu?"

"God, I wish it was the flu."

"What did they die from?"

"Some from yellow fever, some from malaria, small pox, cholera, a bunch of diseases thought to be eradicated or widely vaccinated against, especially in the US. And some victims were infected with several of them."

"Holy shit…" Dean muttered to himself, his eyes narrowed tightly. He pursed his lips. "I'm assuming the CDC's got smoke coming out of its ears."

"Yeah. They're chasing their tails because they've been trying to contain it, quarantine the infected, but it just keeps spreading," Mulder explained. "They can't figure out how."

"Okay, that's weird, but this does seem like a straightforward CDC problem," Dean told him. "Biological weapons attack or something. Why call me?"

"Because each of the deceased had residue of something else in their bloodstream besides the disease they died from and they can't find a reasonable way to account for it." Dean's heart seemed to sink into his chest."I don't know if you've seen this before—."

"Sulfur," Dean breathed, leaning back against the wall and shutting his eyes, massaging his forehead. "Damnit."

Mulder was silent for a moment. "I guess I called the right guy."

"Yeah, you did," he grumbled. Dean paused, chewing on the inside of his cheek. "Listen, are any of the victims acting…psychotic?"

"…What?" Mulder asked, puzzled.

"The infected. Are they becoming violent?"

"Ah, no. No, they're just getting sick and…dying."

Dean paused again. "All right. Hey, how come I haven't heard that the plague is spreading through central Oklahoma?" he asked. "On the news or whatever?"

"Why do you think?" Mulder asked tightly.

"Panic, right, but…I guess what I meant was how have I not heard anything?" Dean asked. "How is this being kept under wraps?"

Mulder sighed, rustling the phone line with static. "That's another reason I called you. I'm not sure how much longer we can keep this quiet. Honestly I was hoping this was up your alley cause that means we don't have all the pieces of the puzzle and explains why we're getting nowhere."

Dean snorted. "Trust me, you really don't. All right, Sam and I'll take off right now. We should make it there in…" Dean checked his watch, "…like twelve hours, if we trade off driving. Where should we stop? I want to park us a good amount from this thing."

"Outskirts of Oklahoma City should be fine," Mulder replied. "That's where I'm at."

"Yeah, by the way, how is it this is your jurisdiction, if you don't mind me asking?" Dean asked, half his mouth sliding up in a smile.

"Ah, it's not really. I'm technically here with Scully working on a cold case that I just got a fresh tip on."

Dean nodded. "Nice. I'll call you when we're close. Call me with any updates."

"I will. Oh, and Dean?" Mulder asked.

"Ya?"

"I want to be honest with you. After we ran into each other a while ago I did some checking up on you and your brother. Did some research on what you guys called 'hunting'. Once I got the last name Winchester it was pretty easy to find your background. And I, ah, talked to a few people who were reluctant or downright stonewalling when I brought you up."

"Yeah, I know," Dean replied simply.

Mulder paused. "You know?"

Dean smiled slightly. "Well, say your friends got a call from some strange guy asking about you. What are they gonna do?"

"They told you."

"Soon as they hung up with you, I got a call," Dean said with a nod. "So thanks for the honesty, but if I didn't think you were on the up and up, I wouldn't have told Bobby to give you my number if you ever called him."

"I see," Mulder murmured. "Can I ask what swayed you toward trusting me?"

"Well, mostly because of your history in the FBI, Special Agent Spooky Mulder."

Mulder chuckled. "Did some research of your own, huh?"

"I have to admit, I was intrigued at the whole FBI-hunter thing from the get-go," Dean replied. "I think you've seen enough to know that what my brother and I do is the real deal, so as long as you're not a moron that means you'll back us up."

"Glad to hear my resume speaks for itself."

"It sure does. See you tomorrow, Mulder."
