When the sun goes down

On my side of town

That lonesome feeling

Comes to my door

The whole world turns blue

Dean laid on his bed and looked to the empty spot next to him. His foolish heartbreak still felt as fresh as it did six months ago. He couldn't help but remember when they had first met. He and Sam had been hunting a vampire. They had caught up with it but got separated and it was about to pounce on Sam when suddenly its head was sliced off just as Dean made it there. Standing there was a girl about their age. She was about Dean's height, shoulder-length chestnut hair, and dark green eyes.

"You ok?" she asked Sam as Dean helped him up.

"Yeah thanks," he said.

"You took the vamps head clean off," Dean said clearly impressed, "pretty badass,".

"Thank ya," she said. Dean took note of her country accent.

"I'm Dean Winchester," he introduced, "and this is my brother Sam,".

"Harper Gates," she said shaking their hands, "pleasure to meet ya fellas,".

"Oh no pleasures all ours," Dean said with his classic flirty smile, "Harper, would you like to join us for a beer or two?".

"Sure," she said. From then on they ran into each other a few times, eventually became a thing and she even eventually moved into the bunker. Dean sighed, getting up and grabbing his keys. He soon found himself sitting in a familiar bar parking lot.

There's a rundown bar

Cross the railroad tracks

I've got a table for two

Way in the back

Where I sit alone

And think of losing you

I spend most every night

Beneath the light

Of a neon moon

Dean walked into the bar and took his usual seat. Heart aching again as it had been a while since he sat there alone. The memories of their times at the bar played through his head. Like the time she beat him at darts five times in a row, or the time she drank more shots than him but didn't get drunk as he did. The one the brought a tear to his eye was the night he taught her how to play pool. She won the first game and then they shared their first kiss. That was the night Dean officially asked her to be his girl.

If you lose your one and only

There's always room here for

the lonely

To watch your broken dreams

Dance in and out of the beams

Of a neon moon

I think of two young lovers

Running wild and free

I close my eyes

And sometimes see

You in the shadows

Of this smoke-filled room

Then the night it all came crashing down played in his mind. It had been a grueling hunt against a small werewolf pack. Harper had almost been clawed to death getting between Dean and one of the werewolves. Luckily Castiel was there to smite it before it touched her. When they got back to the motel she and Dean had a heated argument.

"You should have stayed hidden Harper!" Dean shouted.

"And let that thing attack you, Dean, no way!" she snapped back.

"I had things handled," he said.

"Dean the damn thing knocked the weapon out of your hand and Sam was busy fighting another one," she pointed out, "I had too!".

"You are not going on any more hunts," he said, "that's final!".

"You're not my keeper Dean Winchester," she said, "I will hunt whenever I want,".

"This is why I should have never gotten with you," he said. He regretted that the moment he said it. The tears in her eyes making the feeling worse.

"So what Dean?" she said, "you want me to leave?".

"Harper," he started, but she cut him off.

"No, like you said you shouldn't have gotten with me," she said starting walking away, "the whole lone hunter thing right?. I'll be gone in ten minutes," she rushed out of the room. He has spent every moment since kicking himself for not going after her. He looked toward the jukebox in the bar and for a minute he thought he saw her, but when he rubbed the tears from his eyes she was gone. After about eight beers he decided to head home. He waved to the bartender and headed out to his car. When he looked over to where Baby was parked he froze. Leaning against Baby was Harper. Dressed in her usual gray tank top, flannel jacket, and jean shorts. They just stared at each other for what seemed like hours. "I knew I'd find you under the neon moon," she said nodding to the blue, moon-shaped, neon sign above the bar door.

Dean hurried to her, grabbed her in his arms, and planted a desperate kiss on her lips. It didn't take long for her to melt right into it. When they broke apart he cupped her face in his hands. "I'm so sorry Harper," he said huskily, "I didn't mean what I said,".

"Shh," she said putting her finger to his mouth, "I know, but it doesn't matter now,".

"Please come home," he said, "I miss you so much,". She smiled and kissed his lips again.
