"What are you wearing to my party?" asked Kira chatting with Stiles from behind the counter in the tea shop while Derek served customers.
"Well if you don't need my boyfriend to dress up with you this time I thought I might make him do something with me," he answered.
Derek walked up behind him and asked, "What do you want to do with me?"
Stiles laughed and whispered, "A lot of things."
"We were talking about Halloween costumes." Kira was shaking her head and sharing disparaging looks with Satomi who was talking with customers at the front of the shop.
Derek chuckled, taking Stiles hand in his own even though he was meant to be working not talking to his boyfriend.
Stiles explained, "I thought we could dress up together."
"As what?"
"The greatest fictional gay couple to exist in a fictional reality!" exclaimed Stiles, he seemed very excited about being able to cosplay with his boyfriend.
"Carlos and Cecil?" asked Derek
Stiles frowned, "No."
Kira suggested, "Oh Willow and Tara!"
"I don't want to dress up as a girl," groaned Derek imagining himself in a wig and a dress. He wondered whether he'd be Willow or Tara, probably Tara.
"No, it's two guys!"
"John and Sherlock?" wondered Derek feeling very stuck, "Oh or Solangelo?"
"You read blood of Olympus?" asked Stiles bewildered, "They are a great ship but no, I think we should go as Dean and Cas. You would be Dean of course."
Derek paused for a moment, picturing Stiles in a tie and trenchcoat. With that image in his mind he agreed, "Yeah, that sounds good, let's go as that."
"Okay, good!" grinned Stiles, "I have a samuet, so just dig out some plaid and a leather jacket and we're good to go."
"You're such a nerd."
Stiles beamed, "Yes but you're my boyfriend so I'm your nerd, I have to go to work now so I'll see you later, bye!"
He hurried off before Derek could even respond, leaving him grinning after him like an idiot which Kira teased him for mercilessly.
