When I saw there were no Supernatural/Star Trek Voyager crossovers yet, I wanted to write the first one!

Would love to hear reviews if anyone wants to hear more : )

Tom Paris started it.

He was almost always the one who enticed everyone on Voyager to indulge in his latest holodeck fantasy. There was the French bar, the futuristic yet campy and old adventures of Captain Proton, and Fairhaven, the charming Irish village.

And then B'Elanna encouraged him to move up to television from the early 21st Century – she was tired of black and white shows, frankly, and replicated a DVD player with a month's worth of rations for his birthday. She had searched the database for popular TV programs from the United States at the time collecting DVD's was popular – and discovered one called Supernatural that apparently was very popular in its day.

So maybe it was B'Elanna who started it after all. She downloaded the entire series and put them on those silver discs that went into the DVD player. But it was Tom, after realizing how much fun the show was, who came up with a holodeck program in which the Voyager crew could interact with Dean and Sam, the two main characters. Tom knew B'Elanna had a little crush on both Dean and Sam, and wasn't even jealous, he thought it was cute. He thought he would surprise her – with a face to face meeting with Dean and Sam Winchester.

Plus – Tom had a lot of fun writing up a case for Dean, Sam and B'Elanna to solve – something with werewolves running rampant – something to get B'Elanna's Klingon blood pumping.

It was great, Tom thought. He could barely hide his smirk as they walked into the holodeck and B'Elanna was asking, "So what is this?"

They were standing on a street in an old – fashioned American city – old fashioned because there were streets with cars on them – and B'Elanna saw a black car pull up next to her.

"Oh – my" B'Elanna said when she first witnessed Dean Winchester looking up at her with a concerned look on his face. He – was – gorgeous up close and personal. Heck, he was gorgeous on the show. But in three dimensions – Tom had even created Dean's expressive eyes just right – must have used the whole stock of DVD's and let the computer take notes to create Dean's character, she thought.

Then Dean's cocky smile was coming through – just as perfectly as his expressive eyes - he was aware that a female had taken notice of him, and couldn't help but inwardly pat himself on the back, just like he would have on the show. Then he spoke.

"Hi, would you happen to know where City hall is?" Dean asked. "It's not downtown like it usually would be."

"Oh – my," B'Elanna said, repeating herself. Dean sounded just like Dean. She could see him breathing, his chest rising and falling – he looked so real. She turned to Tom. "Oh my God Tom, this is incredible!"

Dean smiled again. "I know I'm a sight for sore eyes – thanks – but do you know where city hall is? It's kinda urgent."

B'Elanna suddenly stooped down, realizing she hadn't caught a glimpse of Sam yet. There he was, as cute as ever, smiling and waving and saying hi.

"Ohmigosh, there's Sam too!" B'Elanna nearly bounced with joy. "Dean and Sam – oh honey, you are wonderful!" She grabbed Tom and hugged him.

Dean looked really confused. "Uh – do you know us?" He asked.

"Um, yes," B'Elanna said. "You're famous hunters. Bobby told me about you."

"You know Bobby?"

"Computer, freeze program," B'Elanna said. Once she saw Dean's confused look freeze, she said, "Tell me exactly how to get to this city hall they want to get to."

The computer gave her exact directions, she made sure she could recite them back to Dean, and then said, "Computer, resume program."

B'Elanna opened the backdoor of the car and crawled in, motioning Tom to follow her. "I can take you there," She said. She could hardly believe she was in the Impala with Dean and Sam Winchester. This was going to become her favorite holodeck program, for sure.

News travelled fast on Voyager. It wasn't long before practically every female on the ship wanted to schedule holodeck time with Dean and Sam, after hearing what B'Elanna was saying about them in the mess hall. The popularity of the program spread like that Snarnalian flu that hit them a year ago. Except this was much, much more pleasant.

The women were spending all their time allotted for holodeck recreation with the Supernatural program, programming either Dean or Sam to be attracted to them – whoever was their favorite Winchester brother. Dean was the most popular one. The holodeck was booked solid. Even Captain Janeway, couldn't use her rank to get any extra sessions with Dean, and boy, did she try.

Nobody got jealous though - because they were just holodeck characters – and Dean (or Sam) could be programmed to forget all the other women whenever they were with someone. When women were waiting their turn, they'd be in the mess hall, comparing their experiences, trying to top everyone else for getting the best attention from Dean and Sam.

The men were getting a kick out of the program too. Harry and The Doctor were especially having a lot of fun writing up stories to make adventures for everyone to experience. With Tom writing some of the stories too, everyone had a chance to experience a supernatural mystery where they didn't know what was truly going on till the end.

So, Tom Paris started yet another holodeck program that everyone on the ship wanted to be a part of. The men went in with groups – since they didn't care about winning either Sam or Dean's heart. The women found that one going in at a time wasn't allowing for enough bookings – so they started going into the holodeck in pairs – one woman agreed to Sam, the other for Dean.

Janeway even wondered if this obsession was getting a little unhealthy – but when it came to her turn with Dean on the holodeck – all thoughts about that possibility went out the airlock. Nobody seemed to want to give up this new indulgence, and even Neelix was saying it was boosting ship moral greatly. Janeway wondered what would happen if the holodeck went down. Curses, it would be Red Alert!

Everything changed though one day when B'Elanna was saying something to Tom on the side (she was the only woman who went in with a man – Tom didn't want to lose his girlfriend to a holodeck character). She was saying something about when they would get their turn on the holodeck again, and Dean and Sam were in earshot.

Dean blinked. "Holodeck? Did you say holodeck?"

"Yeah, but don't worry about it. Just some code talk for my other job," B'Elanna explained.

"I know what a holodeck is," Dean said. "Are we on a holodeck?"

"Yes," B'Elanna said carefully. "How do you know what a holodeck is?"

"Duh, Star Trek," Dean said. "Okay, quit joking with us. Very funny."

"What is 'Star Trek'?" Tom asked.

"Dean, that might explain what's going on with our case," Sam said. "This one has been more unusual than most. Maybe we really are on a holodeck type environment."

Uh-oh, thought Tom. Sounds like the Doc programmed a really weird one this time. He told the computer to freeze, and then to remove any awareness of the holodeck from the characters. Then resumed.

"Being on a holodeck is too – weird." Dean said. "I mean, Star Trek is in the future, for crying out loud."

Tom felt as if the computer hadn't heard a word he said.

Then the door appeared, and Seven of Nine walked in. "Oh, My God, Sam – it's Seven of Nine! I must be having a really good dream!" Dean exclaimed.

"Me too" Sam said, his jaw falling.

And then Dean turned to Tom and B'Elanna. "I just realized who you guys are. You look just like Tom and B'Elanna on Voyager. Damn, if this is a holodeck, I want to set up some personal time with Seven over there, stat!" He raised his eyebrows several times.

Now B'Elanna and Tom's jaws were falling.
