Young Sam and Dean's eyes widened.  Young Dean snatched his gun out of his waistband, quickly putting it to Dean's stomach.  Young Sam did the same to his older self.  But their older versions did nothing to defend themselves.

Gosh, this is really confusing to explain which Sam and which Dean I'm talking about.  I mean, I could number them, like Sam 1 and Sam 2, but you still have to think.  Let's see...

Oh, I got it!  The younger Sam and Dean are Moose and Squirrel.

"Are you shape-shifters?" Squirrel asked.  "You're a little off on our looks, by the way."  He pushed his pistol harder against Dean's abdomen.  "Silver bullets. Just so you know, I hate shape-shifters who wear my face, accurate or not.  What I want to know is why you look--"

"We need your help, Bieber," Dean interrupted with a smirk.

"Why would we help you?" Moose asked.

"Perhaps we could go somewhere less public?" Sam suggested.  "Like the motel room you were about to crash in."

Moose looked at Squirrel, then shrugged.

"Sam," said Squirrel. "You can't be serious.  They're shape-shifters.  The last one we came across got the cops on my ass!  We should blow their faces off and get back to the case."  Squirrel turned to face Sam and Dean.  "Unless...you two are involved with all of this."

"How about you all shut up and go to the motel?" I said.

They all suddenly looked at me, surprised.

"Who the hell is she?" Squirrel asked.

"Go to the damn motel and I'll tell you," I said.

After much convincing, we finally made our way to the motel.  Perhaps it would have been easier if we'd shown up after they'd made it to their room.  But, no, because if we'd let their minds meditate on the case long enough, then we'd be the ones helping them and not the other way around.  God, this was complicated.  I didn't even know if this would count.

Sam and Dean reluctantly wore hats and sunglasses (yes, at night) when we went into the motel, so the staff wouldn't freak out when they saw two of each person.

Once we finally made it to the room that Moose and Squirrel were staying in, the door was locked behind us, and then guns were once again pointed.

"Dude, seriously?" Sam said.

"All right, macho man," Dean said to his younger self.  "Listen."

Squirrel's brown furrowed.

"We are not shape-shifters," explained Dean.  "We are you."  He pointed at Squirrel's chest as he said this.

"Oh yeah?" Moose said, challenging him.  "And why would we believe that?"

"Fine," Dean said.  He reached for his knife.  "Silver knife."  He sliced his forearm with the blade.  "See?  Not a shape-shifter."

Squirrel's gun lowered slightly.

"Try the salt and the holy water too, if you'd like, but we are you."

"But it doesn't make any sense," said Moose.

"We're from the future. From 2015. We need your help," Sam said.

"Time travel?  Really?" Squirrel was unconvinced.  "How is that even possible?"

"I brought them here with me," I said.

"And who are you, again?" Squirrel asked.  "What are you?  And give me a good reason why I shouldn't kill you."

Sam, Dean, and I exchanged glances.

"She's, um...it's, uh...It's a really long word," Dean finally said.

"Okay. Go on," said Squirrel.

"Um...Pneumonoultramicroscopicsilicovolcanoconiosis?" I said, picking the first random word that came to mind, which was one that I memorized in 7th grade for extra credit.  Dean shot me a strange look.

"Dude, that is long," said Squirrel.

"Isn't that a lung disease?" asked Moose.

"How do you know that?"  Squirrel blurted, giving his brother a once-over.

"It's one of the longest words in the English language," he replied.

"Dude, why?  Why do you care?"

Moose shrugged.

Squirrel raised his gun back up a few inches.  "No more lies."

"Can we please put the guns away?" asked Dean, holding up his hands.  

"Not until we get answers," said Moose.

So, we did our best to explain it.  Besides, they weren't going to remember any of this, anyway.  Because the younger Dean was still at the phase in his life where he refused to believe in angels, something that we all did not want to take the time to prove, we said that I was a witch.

"A witch that can time travel?  That's new."

"Let's just say I'm one of the more powerful ones," I said, causing the door to unlock, then swing open and closed for effect.  Moose and Squirrel raised their eyebrows.

"So, a time-traveling witch brought our older selves here to ask for our help?" Moose asked.

"Yahtzee," said Dean.

"Well that just makes our lives so much weirder," remarked Squirrel, finally setting his gun down.

-

"Woah, Sam.  Everything on you got longer.  That luscious hair, and, boy, those Goliath legs...I bet you didn't get any longer under the belt, though, if you know what I mean, heh heh," said Squirrel.

Dean laughed.

Both Sams jabbed a right elbow into their Dean's side.

"Can we ask...questions?" Moose asked.  I could see in his eyes that he already understood, somewhat, that spoiling their future was a bad idea.

"Yeah.  Where the hell is Dad?  And what is going on with Sam?" tossed in Squirrel.

"Yeah, it would be best if we didn't answer that," Sam said.

"Wait, so if we are still hunting together in 2015, then I never went back to law sch--" Moose began.

"What makes you think that we are hunting together?" asked Dean, avoiding answers to the questions in a way that would just cause their younger selves more despair.

"You actually know what you're doing, basically," Squirrel pointed out.

Sam shrugged at the truth of that statement.  "For the most part."

"So, what are we dealing with?" asked Squirrel.  "...and what's so important about it that you came back from the future for our help?"

"We, uhhhh--" Sam said.  "We did it wrong the first time.  Didn't make the right choices.  We need you to make the right ones."

"Okay, and what are they?" demanded Squirrel.  "I don't like going after this with a blind eye."

"You'll just have to trust us."

"That's it?" Squirrel threw up his hands.  "Sammy, I think I know what we did wrong the first time'.  Something turned us into dicks."

"It's Sam," Moose corrected.

"Knowing too much about your future can cause extreme damage to your lives," I said, trying to make up a convincing argument.  "Just let us help you and you'll understand in ten years."

"But if we change the future, then you won't come back to fix it...How would we understand when the reason never occurred?" asked Moose.  "Isn't this come kind of a paradox?"

Ah, shit.

"It will, uh...come to you in a dream?  You will get a glimpse of the alternate timeline.  Since it's an alternate timeline, there is no paradox."

Squirrel rolled his eyes at how nerdy his brother was being.  "Okay, enough of this Back to the Future crap," he said.  "It's making my head hurt.  I still cannot process the fact that I'm talking to myself!"  He ran his hands through his hair, then let his arms fall to his sides.  "Without a mirror."

"Given all of the things you've experienced in your lifetime, from demons to vampires, this isn't quite so hard to believe, is it?"

"Vampires?" Moose asked.  "They're real?"  No one seemed to hear him or realized what he had picked up on.

"That's monsters.  This is time travel," said Squirrel.

"Yet here we are," interjected Dean.

Squirrel stared at his older self for a moment.  "At least I still look good after ten years. See, Sam?  And I don't eat my veggies."

"Let's run a marathon and see who gives up first," challenged Moose.

"It's on."

"Guys!" I interrupted.

They turned and looked at me.  Dean pursed his lips as he nodded his head forward, annoyed.   His arms were crossed.

"Right," said Squirrel, glancing down at his feet and then back up to me, biting his bottom lip.  He rubbed his hands together.  "So what's the plan?"

"You do what you would normally do while we work in the background," I said.

"What does 'working in the background' involve?"

I gave a small smile.  "We'll worry about that."

"Gosh, you guys are killing me.  Can I at least know whether or not I end up buying the burger I'm hungry for?" Squirrel threw up his hands.

My small smile turned into a smirk. "Yeah, we can't really tell you much, and, even so, I don't even know abo--"

"Buy it," said Dean.  "Don't want to be hungry."

Squirrel tipped his head at his older self with thanks.

"Doing it right the second time," Dean added with a shrug and watched Squirrel head for the door.  "Hey, get me one too."

Squirrel gave a thumbs-up and then climbed into the Impala.

-

The rest of the case didn't really involve us much.  We only shadowed Moose and Squirrel, but out of sight.  That is, until Sam began having visions of people dying.  

No, not just Moose.  Sam.  Sam from 2015.

Both Sams grasped their heads, crying out and crumpling to the motel room floor.  Both Deans hurried to their brother's side.

Call it a mirror image.

"Sammy!" shouted Dean.

"Sam, hey, hey!  What's going on?  Talk to me," Squirrel said to Moose, holding his arms.

Both Sams struggled for a few more moments before freezing and staring forward with a look of horror on their faces.  It was a frightening thing to see from this perspective.

"Why is this happening?" shouted Dean.  "Yellow Eyes is dead!"  Luckily Moose and Squirrel were too involved with each other to hear that factoid.

"I--I don't know!" I shouted back.  Dean cradled his brother, who was almost to the point of sweating.

The visions both ended at the same time.

"Wait," I said suddenly, realizing why this was happening.  "He isn't dead.  This is 2006, remember?"

"So the visions can still happen as long as the demon is alive?  We knew that they were connected, but I thought, since Sam is older, it wouldn't affect him," said Dean.

"Well, turns out that it does."

Sam blinked, wiping his eyes, which had watered.  "I forgot how awful that was."

Moose looked at Squirrel, terrified.  "It's happening again.  Something's gonna kill Roger Miller."

Moose and Squirrel ran off quickly, driving away in the Impala.  Squirrel briefly asked if Sam, Dean, and I were coming, but we decided not to.  The two of them hurried off after that.

You know what happens next.  You've seen the episode.  Haven't you?

Assuming that you have, I'll continue.

-

"This is ridiculous," said Dean, slamming his fist against the table.  "It's not going to work."

"What isn't?" I asked.

"The trial.  No one is helping anyone.  It's just us sitting in this crappy motel room watching porn while Sam and Dean Jr. run around town doing the exact same things that we did ten years ago.  We aren't getting anywhere!"  He shut Moose's laptop.  "This porn is ten years old.  It sucks.  Pixels."

"Dean.  Don't leave it up," Sam said, referring to how Dean did not close the Busty Asian Beauties tab before closing the laptop.  He'd given up an hour ago on trying to keep him off of the computer in the first place.

Dean rolled his eyes, opening the computer back up, listing to the sound effects greeting him back to the website.  He clicked the X at the corner of the screen. 

"Would have been funny to see Sammy Jr. find that," he muttered.

There was a pause. 

"Dean's right," Sam said.

"About the porn?" I asked.

Sam stuck his jaw out momentarily.  "No."  He set his pencil down where he was attempting to complete a crossword out of pure boredom.  "It doesn't look like we are doing a very good job with this trial."

I sighed.  "Well, any suggestions?"

They were silent.

"Lovely," I said sarcastically.  "We're on my last trial, and we don't even know how to ask for help, since we can't affect the future.  I guess I'm not good enough to know how."

"Hey, don't blame yourself.  They're trials.  They are supposed to be difficult," Sam said soothingly. 

"Yeah, but you guys seemed to be doing pretty well with the trials to close Hell."

"I almost died, Nicole."

"But you didn't."

"Because of Dean.   And you don't have to worry about bad health, since the trails are strengthening you.  So, the struggle is in another area."  He stood to his feet and walked to me.  I was standing in the corner of the room.  "I know we will find out how to get through this.  Why?  Because we have these."  He tapped my forehead with his right index finger.  "We'll think our way through.  And we will complete this trial."

I nodded, staring at my feet.

And that's when Sam's next vision struck.
