"Will you quit unbuttoning your shirt?" Teddi asked with a huff. "He doesn't have it unbuttoned in the movie, Billy." She reached forward and buttoned up the remaining buttons on Billy's dark blue plaid shirt. Billy was pouting down at her.

"If I button them all I look like a fucking dork," He argued. He turned to look at himself in the full length mirror that sat in their bedroom, adjusting his red jacket with a frown.

Teddi had gone to goodwill once a week for the last two months until she finally found all of the pieces for their costumes. Billy had finally caved and agreed to be Jack and Wendy Torrence from The Shining. Considering the incident with the mindflayer had made Billy go full Overlook, Teddi thought it would be a funny choice (plus, she had actually hit him with a baseball bat).

Billy and Teddi stood side by side, looking back at their reflections. They looked older, Teddi realized. Like somehow they were peering into their futures. "...We look like we should own a farm." Billy muttered.

Teddi let out a snort, softly elbowing him in the side. "We'd make pretty hot farmers." she joked.

"Obviously." the doorbell rang. Teddi hurried out to the front door, and Billy could hear her greeting all of the trick or treaters and complimenting each of their costumes as she handed out candy. Billy picked up his flask, stashing it in the pocket inside his jacket and heading out to meet her.

He would have been perfectly happy lounging out on the couch with a stack of horror movies, ordering a pizza and handing out candy. But there was a Halloween festival in town that Teddi had been looking forward to all month. So he agreed to wear the couples costume and pig out on funnel cake and caramel apples.

Billy didn't miss the girl with short, golden brown hair dressed as Madonna at the door. He didn't need to see Teddi's face to know the girl reminded her of El. The group of kids thanked Teddi and ran off. Teddi shut the door, turning back with a glazed over look in her eyes. She quickly smiled when she saw Billy watching her.

"You can always call her when you get home, you know." he said, wrapping an arm around her.

"I know...maybe. I don't wanna annoy her," Billy knew that wasn't possible. "We should head out before the trick or treaters start to pick up." she suggested. Maybe it was time for them to take a trip up to visit the Byers. Maybe he could call Joyce and surprise Teddi. Tell her they were going somewhere else entirely.

The pair headed out to the Camaro and Billy flicked on the radio. He groaned when Teddi's Halloween mixtape came on, the Monster Mash playing loudly. She giggled beside him, running her fingers through his curls, tucking some behind his ear and laying her head on his shoulder. "It's one night, Hargrove." she reminded him.

The Halloween festival was bigger than Billy had been expecting from a town like Hawkins. It reminded him a little of the boardwalk back in San Diego. The janky rides and colorful food stalls. He was hit with a wave of memories. All the dates he'd taken to the boardwalk to make himself look good. He liked to win whatever girl he was taking out that week lots of those cheap stuffed animals to impress her and help seal the deal when it came to fooling around in the back of the Camaro afterwards. He'd be lying if he said it didn't make him a little homesick.

"Billy, look," Teddi said, excitedly grabbing his hand and squeezing it. She was pointing over at a ride called Dante's Inferno. It was some tacky dark ride that Billy guessed was supposed to be some sort of torture chamber in hell. It had two levels to it, and a large, red demon that grinned down evilly at anyone approaching the ride. "We totally have to go on that. It's so lame." she laughed.

It was lame. The car was almost too small for the two of them. It had ratty old green seats and grotesque faces carved into the sides of it. Billy guessed it was enough to probably scare some kids, but it all looked almost comical to him. Teddi linked her arm with his tightly as the car took off with a jolt. Billy looked over at her, smiling at the nervous but somehow still excited expression on her face.

Billy didn't really understand much of what they saw inside. There was a track of loud, howling wind and evil laughter playing on loop. Every few feet a generic, "scary" animatronic would light up and go off as they passed. Billy reached over and tickled Teddi on the side a few times, timing it with the animatronic to scare her. She fell for it each time, squealing and jumping before slapping his hands away. "You're such an asshole." she laughed, trying to squirm away from him.

They were both laughing as they stumbled away from the ride. Billy slowed to a stop, his eyes narrowing as he looked at the scene in front of him. "...Isn't that your boss?" he asked, looking over at Teddi. She frowned and looked over. There was Keith standing over by the ticket booth. He was dressed as Jason Voorhees, shifting nervously and looking around as if he were looking for someone.

"Yeah...huh. I can't believe he's he-...oh my god. Is that Cheryl?" she didn't need to ask. It was definitely Cheryl Burns. She was dressed as the Queen of Hearts. Her strawberry blonde hair was swaying back and forth as she sauntered over to Keith, giving him a seductive smile that Billy was all too familiar with before running her hands up Keith's chest.

Billy and Teddi looked over at each other, speechless. "...Am I finally going insane, or does Cheryl Burns have her leg wrapped around Keith and her tongue down his throat?" Teddi asked, blinking wildly.

"Well...to be fair he's probably the only guy in town that she hasn't slept with," he said, attempting to joke. He was way too weirded out to find it funny. "Forget the Mind Flayer, that is the weirdest thing I'm ever gonna see," he said with a shudder. "...How come you don't kiss me like that in public?"

Teddi let out a loud scoff, rolling her eyes and glaring over at Billy. "Why don't I kiss you like your ex girlfriend?"

"Technically she was never my girl-" Teddi cut him off by putting her hand over his mouth.

"Please don't finish that sentence." she groaned.

Billy wrapped his arm around Teddi and pulled her close, burying his face in her neck. "C'mon, Larsson. You're not allowed to be pissed at me tonight. It's our anniversary." he said with a grin.

Teddi raised her eyebrow, trying her best not to smile. "Oh is it?"

"Of course. Two years ago today you fell in love with me at Tina's Halloween party, remember?" he turned Teddi around to face him, smirking down at her as his hands rested on her lower back.

Teddi couldn't fight her smile anymore. She wrapped her arms around Billy's neck, grinning up at him. "Technically I fell in love with the kissing. It took me a little while to fall in love with the rest of you." she teased. If you asked Teddi the moment she'd fallen in love with Billy she wouldn't be able to tell you. It felt like she had woken up one morning and realized she was in love with him.

"Technicalities," he scoffed. Billy leaned down to kiss her, his hand weaving its way up through her hair. It was longer than it had been when they met, and it was back to its natural sandy color. Teddi smiled against his lips, pressing herself closer to him.

"Maybe you're right," she sighed happily. "God, I hate how charming you can be sometimes." that was a lie. Teddi linked her fingers with Billy's pulling him over to the colorful and brightly lit food stalls. The smell of funnel cake batter and powdered sugar was making Teddi's mouth water.

"I was thinking...maybe we should go on a road trip," Billy suggested after they had purchased their dessert. Teddi ripped a chunk of dough that was almost too big for her mouth and ate it. "We've been talking about it for awhile." he reminded her.

Teddi eyed him carefully while she munched on her funnel cake. "Yeah, but where do you wanna go?"

Billy shrugged, taking a bite for himself. He licked the powdered sugar off his fingers while he thought. "...You let me worry about that part," he finally said. He'd never been very good at lying to Teddi. The more simple the lie was the better the chance he had at keeping her off his trail. "What do you say, Larsson?"

Teddi didn't take long to think it over. She didn't need to. The two of them had been talking about taking a nice, long road trip for over a year. It was long overdue. Time for just the two of them. "Just tell me when," she said with a shrug and a smile.

Teddi ended up convincing Billy to go on a few more of the rides. Each one seemed even cheesier than the last. They ate fair food until they nearly got sick, and took turns sneaking drinks from Billy's flask. Billy won Teddi a small army of those tacky, cheap stuffed animals from the game stalls. On the way back to the car she could barely keep the large pumpkin, dracula, little devil and a genuinely creepy looking teddy bear in her arms.

"Thanks for going, Billy." she mumbled sleepily, her head resting on his shoulder.

"Any time, Weird Girl," he didn't think she heard him. Teddi was already asleep, most likely from a sugar crash after all the junk food. Hawkins was pretty quiet. All of the trick or treaters had gone home for the night, and the only people Billy saw out and about where a few costumed adults stumbling out of house parties.

He pulled into the driveway of their little house, where the pumpkins they had carved were still glowing on the porch and got out of the car. Billy opened Teddi's door, reaching over her to undo her seatbelt and easily picking her up. All of her prizes fell out of her arms and onto the floor of the Camaro. Except the evil looking teddy bear, Billy noticed with a groan. "C'mon, Larsson. Bed time." he mumbled, carrying her inside.

Teddi took a deep breath in as she woke up, squinting as she took in her surroundings. "I gotta make a phone call, okay? You gonna be alright getting yourself in bed?" he asked. She rubbed the backs of her eyes roughly and nodded before he set her down. Billy disappeared into the living room. Teddi was too dazed to hear what he was saying on the phone or wonder who he was talking to.

She made quick work of changing into her pajamas, leaving her costume in a pile on the floor before crawling back into bed and hugging the bear Billy had won for her close. She was asleep again by the time Billy made his way back into their bedroom. Joyce had picked up on the second ring. Billy could hear Will and El in the background talking animatedly about some movie they were watching. When he told her his plan, Joyce had been all for it. She told him they could stay in Johnathan's room for as long as they wanted since he was away at school, and she promised to keep it a secret from Teddi.

If you asked Billy the moment he'd fallen in love with Teddi he wouldn't be able to tell you. One minute she was driving him up the wall and the next he felt like he'd do anything to keep her happy...she still could drive him up the wall. There wouldn't be any changing that.

Billy changed and slid into bed next to Teddi. He grimaced down at the black teddy bear in her arms, with its red eyes and fanged smile, and wrapped his arm around Teddi's middle. He pressed a kiss to the top of her head. "Happy Halloween, Teddi."
