Day 7: Cosplaying

Ah, Halloween.

The spooooookiest time of the year, when the barriers between the normal and supernatural are temporarily remoooooved.

Which is all fine and dandy.

But when it comes finding out your respective partner's outfit to your quirky technical analyst's annual Halloween party, then...

"Can you please tell me?" Ashley practically begged.

"Nope. You're just going to have to find out for yourself." Spencer loved it when he was begged for information he wouldn't give - which admittedly was not a common occurrence in his life. So, when the opportunity arose, he took it.

"Just a hint?" Ashley pleaded.

"Nope."

"Spencer, look at me." And she gave him her puppy-dog-eyes-deluxe-edition-with-bonus-tears-threatening-to-spill-over-lashes.

He groaned. No one could resist that face. "You will be the death of me." Ashley grinned triumphantly.

"Only a hint: 708," he replied smugly. Ashley's grin disappeared.

"What's that supposed to mean?" she wondered out loud.

"That is for me to know and you to agonize over," Spencer smirked. She swatted his arm.

"Don't go thinking I won't find out somehow," Ashley warned.

"Right. You just keep telling yourself that."

"You know, I think you need a ego-deflating event. You've been quite arrogant lately."

The night before the big party...

"Well? Do I get to know now?" Ashley called from the bathroom. She had been adding the last adjustments to her own costume, as she had been ordered to stay in the bathroom while Spencer finished up with his costume.

"Okay, you can come out now!"

She walked out of the bathroom...to the sight of her boyfriend in a surgical mask and full doctor garb, wheeling a rectangular cart with a tan cloth stretched out across it. It had artfully drawn eyes, mouth, and veins on it, and a jar full of blue liquid and a "brain" underneath.

"Oh, Spencer," she sighed.

But he was too busy gaping at Ashley's ensemble. "Wha- Who are you?"

"You like?" She twirled, causing her black robes to billow out around her. "I'm Loony Lovegood, o' course." She put on a British accent.

He finally recovered, presumably smiled at her (she couldn't see his mouth behind the mask), and replied, "The Dirigible Plum earrings are a nice touch."

"Right? And they're wonderfully accentuated with the butterbeer cork necklace!"

"Your Spectrespecs are crooked." Spencer moved towards Ashley. As he adjusted the Spectrespecs, his hand touched her cheek, sliding down to the side of her lips. "And you've got something right...here." His fingers touched her lips, causing her breath to hitch.

Unable to control herself any longer, Ashley tore the mask down his face and kissed him. She could feel him grin against her lips.

Once they broke apart, Spencer looked down. "You tore my mask," he noted. "Good thing I have an extra."

"You are such a nerd," Ashley muttered, still flushed.

He gave her that smile she had fallen for. "The drop-dead sexiest, it's been said."

"Oh, my God."

"You said it, not me!"

Just then her phone buzzed with a reminder from Garcia that the party was to start in 15 minutes.

Ashley kissed Spencer on the cheek. "C'mon, we have to go."

He gave her the infamous Spencer Reid pout. "Can't we stay a little longer?"

She gave him a caring, loving look. "No."

At the party...

When they walked in, the hostess scurried over with drinks in her hands and a slightly manic look in her eye. "LOVE the lion head hat, Ash!"

"Thanks, Penelope. You look pretty good, too." An understatement. Garcia seemed to have decided to dress up as a literal tech kitten, with a tail, ears, and whiskers, along with phones, PDAs, and basically any handheld technological device known to mankind, and a few unknowns.

"And my Junior G-Man - what is that?"

"Oh, it's the last pure human from Doctor Who, Lady Cassandra O'Brien.Δ17. She first appeared in the episode 'The End of the World', in which-" Spencer was cut off by Garcia shoving a drink into his hand. "Happy Halloween!" she chirped, and made her escape.

"I get the distinct feeling she's more than a little buzzed," Ashley laughed.

They moved around the room, encountering their other team members; Hotch, dressed as Severus Snape ("You shouldn't have died," Ashley had commented); Rossi, as Master Shifu ("Still got it in ya, old man?"); JJ, as Elsa ("Let it go!" she had cried dramatically); Emily, as Katniss ("Because I can totally rock the side braid and the deadly weapons,"); and Morgan as, of all things, The Rock ("I sure as hell got the body,").

Then Garcia called, "Piñata time!"

Well, between Spencer's extreme possessiveness when it came to candy, Ashley's ability to poke anyone who dared come near her with her wand, and Morgan's sheer brawn to carry him through, the piñata candy was split fairly evenly.

Then came the regular BAU party games: Pin the Murder on the Unsub, Spin the Glock, and Who Took the Murder Weapon from the Crime Scene?

All in all, it was a great party.

But the best part came at the end: Garcia yelled "Group picture!", set a timer on a camera stand, and got a picture of all of them in their Halloween best. She immediately printed out eight copies of the picture and sent each person home with a different homemade frame.

All courtesy of the tech goddess herself, of course.

Spencer and Ashley collapsed on Ashley's couch. Both were so tired from the evening's events that neither even bothered to take off their costumes, although Spencer removed his surgical mask and Ashley took off her lion head hat and set her wand on the coffee table.

"Great party," Ashley said, breaking the silence.

"Yeah, it was," Spencer agreed.

"I think we should probably change into something more comfortable," she commented.

"I'll grab your shorts." Spencer stood up.

"Did I ever tell you you're the best boyfriend ever?" Ashley muttered.

"Yes." Spencer smiled. "Multiple times."

When he got back with the shorts, he turned away as Ashley changed from her robes into them. Stripping down to his boxers, he yanked on an old t-shirt.

Ashley looked at him and chuckled. "Figures."

"What?"

She gestured to the TARDIS emblazoned on his shirt. Grinning, he climbed onto the couch with her, and, needing no words, wrapped his arms around her.

And so they fell asleep in each other's arms.

A/N I know, cliche ending, but I couldn't think of anything better. And as for the costumes for the team members, that was just me playing out my fantasies...I mean, Hotch as Snape? CLASSIC! Also, pardon any inaccuracies, as my knowledge of Doctor Who isn't really extensive enough to formulate a costume based on it. Gotta post this, it's 11:58!

Reviews are love! Also, review with what YOU think the costumes should have been!
