Happy Halloween! This is the end, thank you to everyone who has read this over the past month. I've really enjoyed writing it.

Special thanks to my reviewers Wolflover1989, silversnakes, assantra and CastiellaWinchester94. You guys are the best!

"You two make the cutest Dean and Cas I have ever seen," squealed Kira, "Oh my god Stiles those wings are amazing!"

"Thank you," said Stiles, "You look awesome too."

Kira was dressed as wonder woman. Scott came over to see them and took Kira's hand, smiling his little puppy dog smile at her. He was dressed as a skeleton.

"So this is a thing now?" asked Derek narrowing his eyes at Scott.

"Um yeah."

Derek continued to glare at Scott. "You don't sound too sure."

"Derek!" snapped Kira.

She was an only child and Derek was her best friend so he seemed to be taking on the stereotypical role of older brother.

"No, no, I am sure," he reassured Derek looking terrified, "I mean, if Kira is."

"I am," grinned Kira, "Let's go get a drink."

The pair quickly moved away from Derek and Stiles.

Stiles frowned, "You scared away my best friend and you're best friend. Oh now they're together we can double date."

"Um yeah," replied Derek sounding really unenthusiastic.

The boys went to get drinks then decided to mingle and say hello to all their friends. Everyone in the group had seemed to have coupled off. October had been a strangely romantic month this year.

Despite the severe amount of underage drinking, Lydia had brought her boyfriend Parrish to the party. They were dressed as a cop and a prisoner, but Parrish was the one wearing the orange jumpsuit.

"Something's wrong here," grinned Stiles as he approached them.

Lydia smiled at him, "We decided to change things up."

"Creative," complimented Derek making Lydia beam at him. She didn't know Derek very well but was pleased about how happy he made Stiles.

Parrish and Derek got along pretty well and they decided to make plans to meet up over the weekend.

"Maybe they should date instead," suggested Stiles, "And we could date."

"Stiles I thought you were over me," teased Lydia.

Stiles responded, "How could anyone ever get over you Lydia Martin?"

"I don't know but Jackson seems to have," she replied staring at Cora and Jackson dancing together dressed as a witch and a zombie, "You better watch out for that one Derek."

"Don't worry, she can take care of herself," said Derek but he gave Jackson an unfriendly look as a warning anyway.

The best costume by far was Allison and Isaac who were dressed as Princess Bubblegum and Finn from Adventure Time.

"Someone should have been Jake," criticised Stiles.

Isaac turned around, "I have a Jake on my backpack."

"That's so cute," squealed Stiles before realising how childish he sounded. Despite that, Derek smiled at him like he hung the moon and stars.

The couple went to dance. Derek still didn't like dancing but he decided that he liked dancing with Stiles just because Stiles was a ridiculous dancer, especially when he'd had something to drink, but that only made Derek like him more.

Erica and Boyd were dancing next to them and at some point Erica stole Stiles from Derek, leaving him to dance with Boyd, which was weird.

"Buffy the vampire slayer right?" asked Stiles gesturing to Erica's costume.

"Yeah," she said, "And Boyd is a vampire."

Stiles complimented, "You two look good."

"I know." She winked at Stiles and then kept dancing with him.

At some point Danny grabbed Erica and Stiles, introducing them to his new boyfriend Ethan and then forcing them to do vodka shots

After a while Derek stole his boyfriend back and dragged him to the kitchen where he could get him some water so Stiles could sober him up.

The vodka shots had made Stiles pretty drunk.

"You're the best boyfriend ever you know," beamed Stiles.

"Yeah I know."

Stiles exclaimed, "No but you're really you are suuuch a goooood boyfriend!"

"Thanks Stiles."

Stiles grabbed his boyfriend from behind and hugged him. Derek smiled at his drunk idiot but pulled away.

"Drink this," ordered Derek.

"Yes sir!" replied Stiles saluting him.

Derek laughed, "You are such a strange drunk."

Stiles ignored him completely, switching topics to, "Do you remember when we first met?"

"When you threw toilet paper at me?"

"Yeah," grinned Stiles, "Isn't it so weird that I'm your boyfriend now, like if Scott had been the one to throw toilet paper at you would you be his boyfriend?"

He reminded him, "Scott's going out with Kira and I didn't start dating you because you threw toilet paper at me."

"Really?"

"Yes really."

For some reason Stiles thought it would be a good time for him to sit down and so he lowered himself gently to the kitchen floor, leaning against a wall and stretching his legs out. Derek stared at him for a moment before sitting down next to him.

"Why did you decide to date me then?" asked Stiles after a long pause.

"I don't know," said Derek taking Stiles hand, "I thought you were an idiot when we first met but you sort of got under my skin, you were the first person to ever make me feel flustered and nervous, I couldn't stop thinking about the idiot who threw toilet paper at me at 1 in the morning."

"I couldn't stop thinking about the beautiful grumpy man I threw toilet paper at at 1 in the morning!" yelled Stiles.

"I guess you got your answer then," replied Derek, "We started dating because we both couldn't stop thinking about each other."

Stiles was silent for a moment before he turned to stare intensely at his boyfriend. He told him, "I like you a lot Derek, like really a lot, like I don't love you because it's only been a few weeks and you can't fall in love that quickly but like probably one day I'll be like crazy in love with you."

Derek didn't really know how to respond to his boyfriend's cute ramblings so he just leaned over and kissed him on the top of the head.

"I feel the same way," he whispered, "Happy Halloween."

Stiles grinned at him, "Happy Halloween."7
