The DA's Halloween Party offered various prizes. Best male costume, best female costume … Alex had her eyes set on the best group costume. If she could get enough people together to wear coordinated costumes, then she would win the prize, and they would look cool.

She even had the perfect idea; she just needed to get the supporting cast. The Bureau Chief walked into the one six with an offer they couldn't refuse.

"We get a night of free beer if we go to this costume party that we would have gone to anyway?" Munch questioned.

Fin shook his head.

"I need you to go in the costumes that I choose for you. I want to win the best group prize."

"We're not going to have to cross-dress are we?" Fin questioned.

Alex laughed, "no."

With the 1-6 on board, she had six people. The Captain volunteered too. He had to go anyway, and the costume she had for him was easy to wear. The brass wanted to improve interoffice relations or some crap.

Now all I need is a leading man.

Trevor was amused by Alex's call. "You want me to be your date?"

"You won't be my date," she told him.

"If you're the leading lady and I'm the leading man, how am I not your date?"

She rolled her eyes. "Fine, whatever. You're my date, but don't try anything. My girlfriend is armed, and she will shoot you."

"You're back with Benson?" He didn't hear about it.

"Not exactly."

"You're a badge bunny?"

"If I tell you, will you shut up and go to the party?"

"Sure." Why wouldn't I want to know the gossip?

She explained that she was in a relationship with both Olivia and Casey.

"And for obvious reasons, we're keeping it quiet."

"Damn! Hell if I were you, I'd be bragging."

Of course you would, you ass! "Not if Branch was your boss." Even if he did tolerate gay ADAs, and there were a lot of them, it was unlikely he would support gay, poly ADAs.

"I see your point."

"So keep it quiet, will you?"

"I may as well. No one would believe me anyway."

"How sincere!"

"You know that's what I do best."

Asshole!

The Friday before Halloween, Alex convened everyone at O'Malleys for a drink, or an appetizer in Cragen's case, before they headed for the party.

This was the first time that everyone got to see everyone else's costumes.

Munch whistled loudly when he saw Alex's costume. "Move over Olivia Newton John!"

Alex laughed. She had on the tightest leather pants she could find and a black shirt. She got a perm to make her hair curly, and she had a T-bird's Jacket over her shoulder.

"Please tell me they're taking pictures," Fin questioned.

"I'm sure they will, especially if we win."

"Why are you so excited for this?"

"My Mom loved Halloween. When we were children, she'd have the whole family wear costumes from the same theme." Alex's favorite year, they were the Addams Family. Also, Alex heard some other girls were going to be Josie and the Pussycats, and she wanted to beat them.

Slowly, the cast began to appear. Olivia was Rizzo. Casey was Frenchie. Elliot was Keneckie and Captain Cragen was Coach Calhoun.

With Fin as Putzie and Munch as Sonny, they had everyone except …

No one expected Trevor Langan to be Danny, but he had the hair for it.

"Are those extensions?" Casey questioned.

"Someone dragged me to the gayest hair salon in the world," he glared at Alex.

"Oh hush. You loved all the attention … cause you're a slut."

"I'm a slut? Girl, look in the mirror!"

While Alex and Trevor ribbed each other, the DA's party just got started. People were trickling in, many of them in common costumes like ghosts and witches.

DA Branch was a cowboy and some would argue that's not a costume at all.

As the night went on, the more elaborate costumes came out. One pair came as a banana and a giant spoon from the Rejected comics. There was Cagney and Lacey, Sonny and Cher and of course, Kim Greylek, Sonya Patton, and Jo Marlowe as Josie and the Pussycats.

"We're sure to win the group costume," Sonya told the other girls.

Most people would have agreed until a group of people walked in. Munch's whistle caught their attention.

The DJ for the night was a big Grease fan and immediately changed the song to "You're the One that I Want."

Trevor took his letterman's sweater and threw it to the ground. He and Alex started dancing around the floor, just like in the movie Danny pursued Sandy while she led him about.

The other guests were laughing and clapping.

"Oh this is brilliant," Judge Judy (Lena Petrovsky) declared.

The group really had fun with it.

"I believe you're my girl," Elliot told Olivia.

"You're the jerk who took off when I thought I was pregnant."

"But you're not."

"Well, it was the 70s." They started dancing.

At the end of the song, Trevor picked up Alex and spun her around in front of a clapping crowd.

"Did you know Olivia Newton John was thirty when they filmed Grease?"

"I don't feel so old," Alex was only 32 now. Newton John must be almost 60.

"Think we won the contest?"

"We better!"

The party was in full swing now. Alex headed over to the bar to get a "brandy and sprite."

She got her drink and almost ran into her own boss.

"Liz!"

"Alex," the two women hugged briefly. "Welcome back."

"Thank you. I heard a congratulations is in order." Liz was now a judge.

"Yeah, I get to deal with the riffraff you send me."

"Better you than me," Alex teased.

"Cute," Liz deadpanned.

"I don't know if it makes you feel better or worse, but I may be back in the courtroom sooner rather than later."

Liz's lips curled into a smile. "You still have it." It wasn't a question. "You just have to let it come back."

It was time for the awards.

"Thank you all for coming," Branch said into the microphone. He started off with best seamstress (Dr. Skoda made his own Cousin It costume), scariest costume (Haden was a zombie with a missing eye), and best couple (Carver and his wife were Jay Z and Beyonce).

Then, it was time for the three most contested awards. "Best Male Costume goes to Danny Zuko!"

Trevor bowed after he got his little trophy.

"Best Female Costume goes to Sandy Olsson."

Hopelessly Devoted To You started to play. Alex started lip-syncing for a laughing crowd before taking her trophy.

"Best Group Costume goes to the cast of Grease." They all took a group picture and decided the trophy could live at the 1-6.

Kim was so over Alex Cabot. She came back from the dead, so fucking what?

The party was over and people started going home. Elliot promised his wife he'd get home before it was too late.

"I'll see you all on Monday."

Munch and Fin invited their favorite ladies out for a nightcap.

The ladies accepted and they found a bar nearby.

"I love your haircut," Alex ruffled Olivia's hair. She had cut it short.

"I thought it fit the character. Did you get a perm?"

"I'm washing it out over the weekend. Curls are too much effort to maintain."

"But I'm digging this Sandy look," Munch told her. "Can you at least keep the outfit?"

She rolled her eyes. "I can't wear this to work."

"What about to my apartment?"

Fin punched him. "We just got her back; don't scare her away!"

"What inspired you to pick Grease?"

"I was into musical theatre in undergrad. I got the lead role when we did Grease my junior year."

This was like a Christmas present to Munch. "Please tell me there's a recording of this."

Alex shrugged. Who knows if it still existed what 11 years later?

"So why did you want to win the group costume? You would have killed it by yourself."

"I mainly wanted to shut up Kim Greylek. She's always acting like she's better than everyone and she's been bragging about how she would win all of the good awards tonight."

"You mean this was over petty high school drama," Olivia teased.

Alex stuck her tongue at her.

"Kim and her friends are pretty clicky," Casey admitted. "They call themselves Kisonjo."

"What?"

"Kim, Sonya and Jo. Together that makes Kisonjo and they think they're a big deal or something."

Munch made a face. "How ridiculous."

"Now you see why I had to win!"

Olivia laughed heartily.

It was nice having the blonde back. Fin didn't think they'd see much of her when Olivia decided to stay with Casey, but Alex seemed to be taking it in stride. They all were.

He didn't think twice of it when the three girls shared a cab home. It was only after they left that Munch commented, "I thought Alex lived uptown and Casey and Liv were downtown."

"Knowing Liv, she didn't want Alex to go home alone this late."

It seemed reasonable. It just was inaccurate.
