Author's Note: Hello, Riverdale fans!

So, I watched season one on DVD for the first time. And I watched it again in honor of Luke Perry (R.I.P.). I've seen a few episodes from season two and three on YouTube.

While Betty and Jughead (Bughead) are my main favorite couple, I grew to like Polly and Jason. Yeah, I know, they're related and he's dead; but I think they had potential to be a cute couple.

So, I came up with an idea of doing a Polly and Jason centric story (alternate universe), what would have happened if they succeeded in running away on July 4th. Jason was never abducted by Mustang and later killed by Clifford Blossom, and Polly was never sent away to the Sisters of Quiet Mercy. She manages to escape from her house, unnoticed. Also, how the mystery would have continued (without everyone not knowing Jason's still alive) in Riverdale; with Betty and Jughead trying to figure it out.

BTW, Polly and Jason's babies will NOT be named Juniper and Dagwood in this story. I just think it's ridiculous and Jason would not approve, he'd turn over in his grave.

Anyways, to those of you who shipped Jason and Polly (Jolly or Pason), enjoy! Constructive criticism I'll take, but no flames please. I'll do my best to write Jason in character. I did notice he never said a word, not in the flashback montages nor season one's pilot.

Chapter 1

"Our story is about a town. A small town. And the people who live in the town. From a distance, it presents itself like so many other towns all over the world. Safe. Decent. Innocent. Get closer, though, and you start seeing the shadows underneath. The name of our town is Riverdale.

And our story begins, I guess…with what the Blossom twins did that summer. Plus, the mysterious disappearance of one Polly Cooper. On the Fourth of July, just after dawn…Jason and Cheryl Blossom drove out to Sweetwater River…for an early morning boat ride. Meanwhile, unbeknownst to us all, Polly ran away from home without a trace…

-Jughead Jones

In the early morning hours of July 4th, a red and white Corvette convertible pulls up on the shore of Sweetwater River. Jason and Cheryl Blossom get out of the car and closed the doors.

Dressed in white, they held hands and walked towards a boat.

Turning to her brother, Cheryl asked "Are you scared, Jason?"

Jason hesitates and shakes his head, as a small smile formed; before answering his sister "No, Cheryl,"

The twins get into the boat. Jason began paddling away from the shore, across the water; with Cheryl sitting across from him.

They're quiet for a minute, enjoying their annual ride. Then, Cheryl breaks the silence.

"How much further do we have to go?" She questioned.

"Just until we get to the other side of the river." Jason replied. "Then we'll go our separate ways. You set our 'boating accident' into motion, while I head for Greendale. We'll be there soon;"

Cheryl nodded in agreement.

Prior to the July holiday, Jason confided to Cheryl that he was going to run away, someplace safe. He needed to get away from their parents, Thornhill Mansion, the pressure of taking over the family business, and Riverdale itself. With her help, Cheryl and Jason came up with a plan: stage a boating accident at Sweetwater River and make it look like Jason drowned, trying to retrieve a glove. Yet, they'd make it to the other side; perfectly dry. Jason would contact his sister, once he made it to a haven.

There was a lot more to why Cheryl's twin wanted to leave, but Jason couldn't tell her the real reason; at the risk of blowing his cover. Cheryl didn't dare to question her brother further.

The siblings continued with their voyage, until finally they made it to the other side.

Pulling up to the shore, Jason put the paddles down and steps out of the boat. He helps Cheryl get out.

Holding hands, Cheryl and Jason walk up to the forest part of Sweetwater River. As they walked along, a gun shot rang out, startling them.

"Did you hear that?" Cheryl asks.

"Yes," said Jason.

"What do you think it is?" Cheryl questioned.

"That must be Dilton Doiley teaching his scouts how to shoot." Jason responded.

"Well, this is it. This is where we part ways,"

Cheryl sighed. She was sad that her brother is leaving, but deep down, she knew he had to go. Staying in Riverdale would be soul crushing for Jason.

"I can't believe you're going away," Cheryl said with a hint of sadness.

"I'm sorry sis," Jason apologized. "But I can't stay here any longer. I've got to do this;"

"I understand," Cheryl replied, nodding. "Promise you'll call me?"

"I will. I promise," Jason assured. "And thank you, thank you so much for everything."

The red-haired teens gave each other a sibling hug.

"I love you, Jay-Jay;"

"I love you too, Cher;"

"Be careful, JJ. And good luck," said Cheryl.

"I will. Good luck to you as well, with the plan. Don't tell anyone where I'm going." Jason said.

Cheryl agrees.

They pull away and Jason slowly let go of Cheryl's gloved hand. He walks away.

"Goodbye, Jason;"

Jason turned around and looked at his sister for the last time.

"Goodbye, Cheryl; take care."

Jason continues to walk away and Cheryl goes her separate way.

Jason emerged from the forest and he headed for Greendale. The minute he stepped foot into Riverdale's neighboring town, Jason smiled to himself. So far, so good. Now, all he had to do was meet his girlfriend at the getaway car, on the side of the road.

As he walked, Jason pulled out his phone and saw he'd gotten a text message from Polly Cooper. He couldn't answer, since he was paddling and didn't want Cheryl to get suspicious.

The message read:

Polly: I'm at the getaway car. I'll be sitting behind the trunk of the car.

Jason replies to Polly's text.

OK. Hang tight, on my way. Sorry 4 the delay. I was in the boat with Cheryl. See you soon!

Polly: See you soon, love you!

As Jason continued through Greendale, he looked around. So far, no one suspected a thing. The citizens assumed he was passing by.

Finally, Jason spotted the Blossom Maples Farms sign and the vehicle (under a tarp) parked by it. He had made it to the highway off route 40. As the football jock got closer, he made out a hooded figure lying on top of a suitcase. Hearing footsteps, the figure sat up and stood. The mysterious person wore a long, black hoodie, leather gloves and a mask; resembling a porcelain doll.

Jason pursed his lips and backed away a bit; nervous. He expected to find Polly, but instead, found someone else. He didn't know what to make of it.

But to his surprise, the figure held up a gloved hand; as if to say "wait."

With a free hand, the person pulled back the hood, revealing two blonde ponytails and a headband. The mask is lifted, and a familiar face with green eyes looks back at the red head.

"Jason,"

A/N: Take a guess who it was…I'm sure you know.

And as for the incest thing, I've decided that in my AU story, Polly and Jason will not be related as third cousins. It's biased on social media, especially Instagram. Some consider Jason and Polly's relationship incest, and some don't; because they're third cousins and there's a less than 3% chance they're related. Debate all you want in the reviews, I think them being related ruins the chance of being a couple (other than Jason being dead on the show).

In the next chapter, Polly explains to Jason how she escaped from her house.

Anyways, don't forget to review, favorite, and follow! Another chapter coming soon!
