Olivia shifted in bed and hugged Mark around the stomach.

"Baby move your knee." He mumbled sleepily and pushed her knee away from his crotch.

"Sorry." She mumbled and cuddled more into his arms.

Their door opened to their room. Mark opened his eyes and spotted Lilly standing there dressed in her Tinkerbell Halloween costume. "Hey princess."

"Is it James?" Olivia teased with a smile as she kept napping on her husband's chest.

Lilly smiled and came to their bed. "Daddy let's go." She started pulling Mark by the arm.

"Where?" He pulled her back. "You sleep walking kiddo?"

"No." She rolled her eyes. "We have to go trick or treating."

"Not at seven in the morning we don't." he kissed her on the cheek. "C'mon let mommy and me sleep."

"Mommy has to go to work." Olivia answered and didn't bother opening her eyes. She knew full well Mark took care of all the kids when she had to work.

Lilly pouted at Mark. He pouted back. "Who got you dressed anyway?" Mark questioned as he rubbed Olivia's back gently.

"Zane. He didn't want to at first but I bothered him. Now I'm tinkerbell" She held up her arms. "Do you like it?"

"Yeah baby." Mark kissed her on the head. "But it's too early to trick or treat. You want to be tinkerbell in the living room?"

"Daddy." Lilly whined. "What are you dressing up as?"

"The sleeping man." Mark winked and pretended to fall asleep.

The twins came into the room and started jumping around.

Mark opened his eyes again. Matt was in a Ninja outfit and Mike had his jeans hanging low with a baggy hoodie. "Take whatever you want, just don't hurt me." Mark teased with a smirk. "Mike what are you supposed to be? Zane?"

"No. Zane said I should be ghetto. I don't know what that is but it's comfortable." Mike answered and pulled his pants up. "Mommy my pants are falling."

"Get a belt." Olivia answered sleepily and turned to the other side. She got home from a case at three in the morning and was craving sleep that her children weren't letting her have.

Mark noticed Olivia's tired attitude. He got out of bed. "Ok guys, let's go be gangster ninjas and tinkerbell's in the kitchen." He kissed Olivia on the cheek and led the kids out of the room to let Olivia rest.

Mark chuckled spotting James dressed in a nice suit with his hair combed nicely to the side.

James fixed his tight vest under his blazer. "How do I look?"

"Like an accountant." Mark smirked. "Who are you?"

"You." James answered. "Can I borrow your badge for the night?"

"No." Mark answered weirdly. "I don't dress like that."

"Yes you do. When you had a big federal conference. But c'mon, let me borrow your badge. I have Halloween parties to go to." James pleaded. "I promise not to break laws with it."

Mark rolled his eyes. "Top left drawer in my room." He started fixing breakfast for the twins and Lilly.

James smiled and went to his parent's room. He slowly walked to the drawer seeing Olivia sleeping.

Olivia opened her eyes hearing someone in the room. "Wow. Who are you proposing to?"

"No one. I'm a fed." James grinned. "Do I pull it off?"

"Get your dad's badge." Olivia smirked and looked at the clock. "Hey give me my jeans."

"Lazy." James mumbled and grabbed a pair of jeans from a shelf and tossed it to her.

Olivia looked at the big size. "These are your fathers."

James threw his hands up in the air. "Well I don't know." He looked through the shelf full of jeans and found a small pair. "Yours?"

"Yes." Olivia nodded. He tossed them on the bed. Olivia put them on under the blanket since she slept only in her panties.

James saw that the drawer was locked. "A little help?"

Olivia got out of bed and covered his eyes with her hands as she put in the code for the lock. "No peeking."

"What am I five years old? I'm not going to steal your gun and pretend I'm a cowboy."

"Could be a G.I. Joe." Olivia teased and found Mark's old badge by their weapons. She closed the drawer and locked it again. "All clear."

James moved her hand off his eyes. "Let me get the badge." Olivia gave him a warning look. "Please." He quickly added.

Olivia opened his blazer and put the badge on the inside pocket. "More fed like that."

"Thanks." James nodded. "Hey did Cameron really ask you guys if he could marry Jenny?" he lowered his voice.

"Yeah. We gave him permission."

"You mean you did. Dad wouldn't even let her have a boyfriend if it was up to him." James smiled.

"Same thing. Stop harassing Cameron, he is a nice kid and loves Jen."

"I don't harass him." James defended. "It's called being protective."

"Well don't be so protective." Olivia answered. "If Jenny is happy that's all that matters."

"So can I harass him when she's not happy with him?"

Olivia thought about it. "Maybe just a little." She winked and kissed him on the cheek. "You look very handsome by the way."

"Thank you Madame." James smiled and left the room.

Mark came in a couple minutes later. "Hey Cameron's parents are having a Halloween party, they invited us to come over."

Olivia took off her shirt and started to look for her bra. "I'm going to be at work all day. You can go if you want though."

"I'm not going to go alone." He sat down on the bed and watched her looking through her closet. "No chance of you getting out early?"

"No I'm sorry baby." She put on her bra then grabbed a blouse. "I know you need some fun time and not just taking care of the kids all day."

"I don't feel manly being a stay at home dad." He stated with a small shrug.

"Baby." She looked over at him. "I know it's probably not very fun having to feed them and make sure they don't kill each other but you shouldn't feel unmanly because of that. You're a good dad and an amazing husband."

He shrugged a little. "I know. Thanks."

She sat down in his lap. "I love you."

"I love me too." He teased with a smile and pulled her closer. "Can I get some treats tonight?" He winked.

"Depends…what are you dressing up as?"

"The naked horny husband." He grinned and gave her a kiss.

"I love that costume." She laughed and got off his lap. "I have to go be a detective now."

"Seen it before." He stated with a smirk. "Be a nurse!"

"In your dreams." Olivia grabbed her gun and badge. "I'll call you later." She gave him a quick kiss. "Love you." She left in a hurry knowing she was going to be late to work.

Mark got dressed knowing the kids we're going to be hyper all day. As he put on his belt Lilly came into the room crying. He quickly kneeled down. "Honey what's wrong?"

"My dress ripped." She answered and wiped her eyes as she hugged him around the neck.

"Aww baby." He noticed the seam ripped a little. "Told you not to jump around so much."

"Where's mommy? She knows how to fix it."

"Mommy went to work." He kissed her head. "I don't know how to sew but we can go buy you a new costume."

"No." She started crying again. "I like this one."

"Ok." He nodded realizing the kids would get attached to one new toy and wouldn't want to change it for days. Same with Halloween costumes. "You want daddy to try and fix it?"

"Yeah." She nodded and wiped her eyes again.

Mark picked her up and carried her to her room to change her costume so he could attempt to sew it for her.

-------------------------------------------------------------------------------------------------------------------

Olivia yawned once again as she looked over evidence for the case.

"Tired?" Elliot questioned.

"You think?" Olivia rubbed her eyes. "The kids decided to dress in their Halloween costume and wake us up early."

"I know how that goes. At least half of them are already grown."

"A little too grown." Olivia shook her head. "Jenny's boyfriend asked us permission to ask her to marry him."

Elliot raised an eyebrow and instantly spotted his son standing in the doorway of the precinct overhearing Olivia's statement. He quickly got up. "Hey."

Dickie just stared at Olivia. "She's engaged?"

Olivia looked up and instantly regretted what she said. "Um…not yet but will be."

"I thought she wasn't ready."

"Dickie c'mon." Elliot tried to calm him down.

Olivia got off her chair. "Dickie sorry she turned you down but that doesn't mean she can't ever be ready to be married."

Before anyone could say anything, they heard yelling down the hall. Olivia and Elliot looked over and spotted John and Fin leading their suspect down the hall.

"Go home." Elliot told his son in a small whisper. Dickie rolled his eyes and left the squad room.

-------------------------------------------------------------------------------------------------------------------

Mark sat in the living room trying to figure out what to do. "Lilly you sure you don't want to be a gangster like your brother?"

"Yes." She answered and watched her father trying to sew.

Mark nodded. "Just checking. What about a cool pirate?"

"Nope."

"Ok." He nodded disappointedly.

Zane came into the room and hi-fived Mike. "How's it hangin' playa?"

Mike pulled his pants up again that were down to his butt and had his boxers showing. "Very low."

Zane smirked and pretended to do a karate move on Matt. Matt laughed and did the same being very excited about his ninja costume. "How's it going tinkerbella?" He questioned Lilly.

"My dress ripped. Daddy doesn't know how to fix it." Lilly answered with a pout.

Zane sat down by Mark. "I'll do it."

"You know how to sew?" Mark asked with a raised eyebrow.

Zane shrugged. "Yeah. My mom taught me."

Mark nodded and handed it to him. "Thanks man." He got off the couch and started to leave the living room. The twins followed. "Guys I'm going to the bathroom, I'll be back." He told them.

The twins nodded and went back to Zane.

Mark just shook his head trying not to be annoyed with the kids never giving him privacy.

------------------------------------------------------------------------------------------------------------------

Olivia and Elliot sat across their suspect questioning him.

"Where were you last night Foster?" Elliot asked.

"Home." He answered.

"Really?" Olivia questioned. "There are photos of you hanging around the federal plaza last night. A block away from where you raped and killed your victim."

"I didn't kill anyone."

They heard a knock on the door. Casey opened the door. "Detectives."

Elliot and Olivia got up and went outside. "What's wrong?" Elliot asked.

"Feds have Foster as their suspect also."

"Suspect for what?"

"They wouldn't say." Casey shrugged. "I need a confession or we can't hold him. He goes into federal custody and we are going to lose our case."

Olivia spotted Brad and another agent coming through the doors. "It better be your anniversary Casey."

Casey turned around and spotted her husband walking toward them. "You're not getting our suspect Brad."

"Of course not." Brad answered. "Is he in there?"

"Yes he is." Elliot answered. "He is in our custody."

Brad laughed and walked past them. He went into the interrogation room and pulled Foster up. "Let's go." He pulled him off the chair and handcuffed him. "It's your collar Franklin."

"What the hell do you think you are doing?" Casey snapped.

"National business." Brad's partner answered. "Stay out of this." Franklin ordered.

"Shut up." Casey snapped at him.

"Excuse me?" Franklin stepped in front of her.

"Back off." Brad ordered. "Step away from her now."

Franklin did as ordered and stared at the detectives as Brad led Foster out of the room.

Cragen came out of his office spotting the incident. "What's going on?"

Brad simply pulled up his badge. "It's a matter of national security, captain. Sorry." He shrugged at his friends. "If you have any more questions for him, call me." He looked over at Casey with a small smile. "You know the number."

Casey stared at her husband angrily. "See you in court sweetheart."

Foster let out a laugh. "Who? Me? See you also baby."

Brad hit him upside the head. He grabbed the back of his neck and led him out of the squad room. Franklin followed.

Everyone looked over at Casey. Casey rolled her eyes and just walked away without a word.

-------------------------------------------------------------------------------------------------------------------

Later that afternoon, Casey followed the judge down the hall on one side and Brad on the other.

"Your honor the federal agency is obstruction justice. They arrested our suspect in our precinct during an interview."

"Is this true Agent Stewart?" Petrovsky questioned.

"No your honor, the detectives we're outside of the interrogation room. There was no interview being conducted." Brad answered.

"He was in our interrogation room." Casey snapped. "What do you think happens in those? We sing songs?"

"Nobody was talking to him. You didn't charge him. It was fair play." Brad answered.

"Your honor the bureau hasn't even stated why they are arresting Mr. Foster. We have the right to know if it's connected to our case."

"It's not." Brad answered. "We don't need to tell you why we arrest someone."

"Ever heard of the Patriot Act agent Stewart?" Casey smirked at him as they went into the office. "You have to share information with us."

"Have to? This is a matter of National Security counselor, not a rape case. Our cases are far more important than yours."

"That's enough Agent Stewart." Petrovsky ordered. "Was Mr. Foster arraigned?"

"No." Brad answered defensively. "He was just a suspect. They didn't even read him his rights yet."

"We were until you're little army trampled over about a dozen laws in less than ten minutes."

Brad just rolled his eyes.

Petrovsky nodded. "I can't charge the federal bureau with obstruction but we will split this." She answered. "The police can have Foster for 24 hours. If by then the NYPD does not get a confession, the FBI gets him."

"With all due respect your honor, we can't agree with that." Brad spoke up.

"Are you kidding me?" Casey asked. "The people are the ones getting screwed here. 24 hours? C'mon grow up Brad."

"Apparently your detective can make people talk in a matter of ten minutes. I heard that right hand of his is handicapped." Brad smiled. "I don't trust the NYPD interrogating my suspect. I'll interrogate him, if he confesses to your rape case I will let you know."

"You think I trust you with that?" Casey snapped. "No. We get him for 24 hours."

Brad just stared at her. It suddenly became personal. She didn't trust him?

"Sorry Agent Stewart. 24 hours it is." Petrovsky answered.

Brad nodded and left the office. Casey followed him. "Thanks for screwing me over." Casey snapped.

"Yeah. Thanks for not trusting me." He fired back and walked in the other direction.

----------------------------------------------------------------------------------------------------------------

"Daddy can we go trick or treating?" Lilly whined as she sat on the couch playing with her dress.

"No baby, it's raining." Mark answered and flipped a channel.

"No it's not." Matt whined as he stood on the couch and looked out the window.

Mark got up and went over to them since all were standing on the couch looking at the pouring rain. "Dude its pouring rain out. You're not going out now." He went over to Mike and pulled his jeans up. "Just so you know, this is only for Halloween, you're not allowed to dress like this any other time." He kissed his head. Mike nodded.

"Daddy this isn't fun." Lilly whined again.

"You guys want to play monopoly?" Mark offered.

"No." All three answered.

"How about we rent a movie?" He asked again. "C'mon you guys like movies."

"But we wanted to go trick or treating." Lilly whined and looked over at her father. "Why is it raining?"

"Well you see," Mark picked her up and placed her on his shoulders. "Negative and positives meet in a cloud and it starts to cause humidity which then causes rain."

"Daddy." She whined. "I didn't mean that."

"Well you asked." He patted her back. "C'mon guys, you're depressing me just watching the rain. Let's do something. You guys want to eat?"

All three shrugged. "Can you make us Mac and cheese?" Mike asked.

"Sure." Mark answered and motioned for them to follow. "Let's go troops."

All three followed their father.
