Later that night Liz and James went out on a date and Zane went out with some friends. Casey and Brad took Lilly to stay at their place since the twins wanted to see Ben. Jenny went out with Dickie on a date and Mark and Olivia were left alone in the house.

Mark sat on one end of the couch as Olivia just flipped channels and ignored him on the other end of the couch.

"We can't just ignore each other the rest of our lives, we do sleep in the same bed you know?" Mark spoke up looking over at her.

"This isn't the time for your dumb jokes" Olivia kept looking at the TV and pretending that she had no more interest in him.

"You used to like my jokes"

"You used to keep your dick in your pants"

Mark said nothing and looked down at the ground. "I don't know what you want me to do anymore. I said I'm sorry a million times and I would do anything for you to forgive me"

"Can you go back in time and keep your pants zipped up?" She threw the remote on the table, got up and went to their bedroom.

Mark got up and followed her into the bedroom "Olivia we have kids you can't just get rid of me"

"Watch me" She opened all his drawers and threw all of his clothes at him "Get out"

He shook his head "No"

She got all of his clothes from his closet and threw it at him "Get out!"

"No! I want to talk about this!"

"Fine! How was she?" Olivia yelled at him.

"What?"

"You said you wanted to talk about it! How was she Mark!"

"She…she's nothing compared to you I swear"

"Oh cliché line sweetheart"

"Look I'm sorry, what do you want me to do?"

"Get the hell out of my house would be for starters!" She pushed him out of the door of their bedroom.

"C'mon Olivia don't do this please"

"I can't look at you right now so it would be better if you would just leave" She crossed her arms on her chest and looked at him trying to hide her emotions.

"I'm so sorry, please don't do this. You think this is the best for Lilly or any of the kids?"

"You should have thought of that before you let your boss blow you, now get the hell out!"

"Oh c'mon you think if I gave up on you every time you made a mistake we would be here?"

Olivia grabbed a magazine from his nightstand and started to hit him with it.

"C'mon!" He protested as he grabbed the magazine from her hands "Enough!"

"I never cheated on you, you bastard!"

"What about Aaron!" He yelled back even though he new it was a cheap shot.

"That was totally different and you know it! He kissed me and I was drunk!"

"Like mother like daughter!" He yelled back and knew he crossed the line immediately. He handed her the magazine back knowing she wanted to hit him.

Olivia grabbed it and hit him over the head a couple of times and then threw the magazine on the floor. She crossed her arms on her chest and just looked at him.

"C'mon Olivia remember when you dumped me? If I gave up on you those two weeks would we be here? I didn't give up on you then and I never will…so please don't give up on us…please?" He whispered as he touched her arm. "Please baby?"

"I never thought I would regret taking you back but I guess I just proved myself wrong," She whispered as she sat down on the bed and wiped her tears away.

"Don't say that" Mark kneeled down in front of her and took a picture he had of the kids on his nightstand "Do you regret this?"

Olivia didn't answer and just looked at the picture.

"Olivia do you regret having them?" He whispered.

"No" She whispered and shook her head "But I regret trusting you so damn much" She took the picture and put it back on the nightstand.

"Don't say that. C'mon I made a mistake and I admit it, I'll be a man about it and tell you that I should have done something more to stop it but I know that wont make up for what I did. I love you too damn much Olivia." He whispered as he put her hair behind her ears. He put his head on her lap and hugged her around her waist knowing it was the end and he didn't want to let go of her.

"Mark" She whispered as she picked his head up and made him look at her "You always protected me from other people and I love that about you…but why couldn't you protect me from you?" A tear rolled down her cheek "Mark I want a divorce"

"No" He whispered and shook his head. He wasn't able to keep his tears back anymore and let a tear fall down his cheek "I'm not giving you a divorce"

"Mark you're not the same…my husband wouldn't do that to me. It's best for us to keep away from each other," Olivia whispered as she wiped his tear away.

"No" He shook his head again "Olivia I cant live without you. I cant live without your heart" He placed his hand gently on her chest "Or your smile" He gently glazed his thumb over her lips. "Or your amazing talent to make me laugh and make fun of me" He whispered with a small smile.

Olivia smiled a little "I don't know if I can trust you again Mark, I'm sorry" She wiped her tear away.

"No. C'mon it's me, if you can't trust me then who can you trust?"

"I don't know," She whispered with a shrug.

Mark didn't hide his tears and just rested his head on her lap "Let me be there to hear my daughters first words please? I want to walk Jenny down the aisle only if you let me. I want take the twins to their first day of school and tell them that it won't be so bad. I want to be the one that ties James's bowtie on his wedding day. Olivia don't take that away from me please?"

Olivia kissed him on the head and started to cry "You took it away from yourself honey. It's your fault not mine" She whispered as she untangled his arms from her waist and got up and went to the bathroom.

Mark put his head on the bed and started to cry knowing that it was his entire fault. "Fucking gun" He choked out through tears wishing he were dead right now. It would make it easier then the pain and guilt he was feeling for ruining his own family.

Olivia sat on the edge of the bathtub wiping her tears away. She knew that it would be hard for the kids knowing Mark wasn't going to be around but she couldn't still be with him after what he did. She admitted that she was still in love with him but she couldn't see him the same way imagining him getting oral sex by the woman she hated the most.

Brad let out a deep breath since he was taking care of the twins and Casey was taking care of Lilly and Ben.

"Can we watch a movie?" Mike asked as he started to jump on the couch.

"No it's sleep time," Brad answered as he picked him up and put him back on the couch.

Matt got on the couch and started to jump on it as well "What about cartoons?"

"Sleep time" Brad answered as he put him on the couch as well. "Let's go" He picked both of them up and carried them into his room.

Casey put Lilly to sleep by Ben and covered both of them.

Brad put the twins on his bed since they were sleeping in Casey's and his bed and Casey and him were sleeping on the couch.

"Guys be quiet so Ben and Lilly don't wake up ok?" Casey whispered to the twins as she covered them with a blanket.

"Can we watch a cartoon and fall asleep with it?" Mike asked.

"Without volume yes" Brad answered as he took a DVD and put in the TV they had in their room and put it on mute. "Now sleep. If you need anything we're in the living room"

"Goodnight" The twins said in unison and waved at them.

Casey and Brad waved and went out of the room. Casey closed the door behind them and flopped down on the couch. "Oh boy"

Brad lay down on her and rested his head on her shoulder. "Four kids are tiring. How do Mark and Olivia do it?"

"I'm pretty sure they are superheroes," Casey teased with a smile as she gave him a kiss on the cheek.

"Yea superheroes that are lucky enough to be having sex right now" Brad mumbled as he buried his face in her chest "I want sex" He whispered as he put his hand under her shirt and cupped her breast gently.

Casey giggled and wrapped her arms around his neck "Not tonight"

Brad groaned and pulled her shirt off "Why?"

"Cause I said so" Casey whispered "No more touching"

Brad purposefully made a puppy face "Bradley wants Casey Novak…correction he wants her butt and breasts"

Casey tried to contain her laughter not to wake the kids up "Don't make me laugh"

"But I like your laugh" He pouted and kissed her neck.

"When are we going to get married?"

"It's not like you have been saving yourself for after your wedding and I'm your first "

"Not that" Casey rolled her eyes and slapped him on the chest "We have been engaged for about nine months now and we hardly made any plans you know?"

"I don't know, when you want" Brad answered with a shrug and returned to kissing her neck.

"I'm up here buddy"

Brad looked up at her and gave her a kiss on the lips. "I don't mind kissing your sexy lips either" He started making out with her.

Casey giggled and rolled her eyes but kissed him back.

Mark and Olivia heard the doorbell. Both quickly wiped their tears away and got up from where they were. Mark was the first one out of the room as Olivia tried to cover up her tears.

He went to the door and opened it. He looked at James standing there with two men behind him "Yea?" He asked totally confused and just looked at James.

"Are you his father?" The older man asked.

"Yea. What's the problem?"

"We caught him with other boys that were smoking marijuana" The younger man answered.

Mark looked at James and gave him a look "Go to your room"

James said nothing and did what he was told.

Olivia came out of the bathroom and went to the door. She walked past James and could tell something was wrong. She went over by Mark and her eyes quickly settled on the younger man standing in her doorway. "Cassidy" She said in almost a whisper.

Brian Cassidy quickly looked over at her and a small smiled appeared on his face "Olivia"

Mark looked at his wife and then the younger detective. "You two know each other?"

"We used to work together," Olivia explained. "What happened with James?"

"We caught him with some kids that were smoking marijuana but we found none on him so we just brought him back here cause he showed us who his father was" Brian answered and kept looking Olivia "So you're married to a federal agent?"

"Close to divorce" Olivia answered with a smile purposefully trying to get Mark jealous even though she couldn't believe her own words.

Mark quickly looked over at her and her words were like a punch in the stomach. He said nothing not wanting to make things worse.

"Oh. Hamilton can you go wait in the car, I'll be right there" Brian said looking over at his partner. His partner did was told of him.

"Mark can you go talk to James?" Olivia said looking over at Mark.

Mark just looked at her and then Brian and instantly felt protective and jealous. He said nothing and went up the stairs. He quickly walked into James's room.

"Look dad-" James started thinking that Mark's fast paces were about him.

"Just be quiet" Mark cut him off and quickly opened his bedroom window. He climbed out and pulled himself on the roof so he was directly above the front door and he was looking over Olivia and Brian talking.

James climbed out of the window and joined him "What's going on?" He whispered.

Olivia looked up hearing some kind of noise. Mark quickly put his hand over James's mouth and pulled him back from the ledge so they weren't visible.

"So Olivia now that you're divorced want to go on a date?" Brian asked with a smile.

James looked over Mark and opened his mouth to say something but Mark motioned for him to be quiet.

"Well um…" Olivia knew that she didn't want to go on a date while she was married but knew it would drive Mark insane and jealous. "Yea that sounds great"

"Dad-" Mark quickly covered his mouth.

"Do you want to be grounded for the rest of your life?" Mark whispered to him. James shook his head "Then be quiet"

Olivia looked up but saw nothing even if she did hear some sort of rustling.

"Pick you up tomorrow at seven then?" Brian asked grinning happy that he finally had a date with one of the most gorgeous women he ever met.

"Can't wait" Olivia said with a smile and went back into the house "Bye" She waved and went into the house and closed the door.

"Bye" Brian waved with a smile.

Mark grabbed a penny from his pocket and threw it at Brian and hit him in the head. James and him quickly moved back when Brian looked up.

Brian said nothing and walked back to his squad car.

"Dad what the hell is going on?" James asked looking over at Mark when Brian drove off.

"Marijuana that's what. Get in the house" Mark ordered and pointed to the window.

James rolled his eyes and went back to his room. Mark took a deep breath not believing that Olivia was actually going on a date. He climbed into James's room window and stopped seeing Olivia standing there with her arms crossed on her chest. James was sitting on his bed looking back and forth at his parents.

"Spying on me?" Olivia asked with a deadly stare.

Mark gulped and shook his head "No"

"Lying?" Olivia asked.

"Yes" Mark answered.

James looked at them and totally felt confused and uncomfortable. "Um…what is going on?"

Olivia looked over at him and grabbed his cell phone from his jacket "You're grounded"

"Mom I wasn't smoking it-"

"And no seeing Elizabeth for a month" Mark added.

"Dad!" James yelled shocked and quickly looked over at him.

"And no hanging out with your friends for two months" Olivia added.

"Hey if you two are having problems don't take it out on me" James protested.

"Excuse me I have to get ready for my date" Olivia smiled at Mark purposefully and went out of the room.

Mark's mouth dropped and he shook his head "Damn that's cold"

James looked over at him "So what's up with you guys?"

"Divorce" Mark answered in a low voice and went out the window and to the roof. He sat on the roof and just looked at the night sky.

A couple of seconds later James joined him "Divorce?" He asked as he sat down by his father.

"Divorce" Mark nodded.

James looked at the ground and played with the small pebbles "Why?"

"James do you love Elizabeth?" Mark asked looking over at him.

He nodded "Yea, she's hot"

Mark smiled a little "Then treat her well ok?"

"Yea" James nodded still confused.

"Hey no matter what happens, you're always my son ok?"

James nodded and hugged him "Yea"

Mark gave him a kiss on the head "If you have problems I want you to talk to me ok?"

"Of course" James whispered with a nod "You and mom will work it out right? I mean you always do"

"I made a big mistake so I really don't know alright? But if your mom and I aren't together then you're the man of the house ok?"

"You got it"

Mark nodded "And don't give her trouble, when we punish you its for your own good so you better start cleaning up your act, promise?"

James just nodded. "Promise"

"Goodnight kid" He patted him on the shoulder and got up and went inside.

He went down the stairs and inside their bedroom.

Olivia was standing by her closet purposefully trying to act like she was excited for the date but she wasn't one bit.

"You're not really going to go out with this guy are you?" Mark asked as he sat down on the bed.

"Of course I am. I'm moving on and I bet Cindy would be happy to hear that so are you" Olivia smiled at him trying to seem as cold as she could toward him even if she didn't want to picture him kissing Cindy.

Mark looked down at the ground and shook his head "You actually expect me to be with her? I didn't want it in the first place then why would I be with someone who ruined the best thing in my life?"

Olivia looked at the ground for a second but then quickly looked up trying to hide her feelings that she still had for him. "You're sleeping on the couch tonight"

Mark nodded and said nothing. He grabbed a pillow and blanket from the closet and went into the living room.

Olivia lay down in her bed and just stared up at the ceiling. She slowly drifted off to sleep wondering if what she was doing was the best thing.

Mark lay on the couch staring at the ceiling not being able to sleep wondering if his marriage was over. He heard the key in the lock and knew it was Jenny.

Jenny came in quietly and closed the door behind her slowly.

"Busted"

She quickly spun around and found Mark watching her. "Hey dad"

"Past curfew isn't it?" Mark asked raising an eyebrow.

"The movie ran late sorry" She whispered as she came in the living room "Why are you on the couch? I mean if you have a blanket while you are waiting for me I think you are getting really old for this dad" She teased with a smile.

"Funny" Mark smiled at her and shook his head "Marriage problems"

"Want me to go find out from James or do you want to tell me?" Jenny asked as she sat down by him.

Mark rolled his eyes knowing James and Jenny told each other almost everything "I'll do the honors" He sat up on the couch. "Your mom and I are getting a divorce"

"What!" Jenny yelled out.

"Ssshh" Mark shushed her "Do you have to wake up the whole neighborhood?"

"Sorry" Jenny whispered with a shrug "Why?"

"Its complicated but I'm at fault and I admit it" He gently stroked her hair "How are you and D?"

Jenny chuckled "Only I call him that dad"

"Hey your old man is cool right?"

Jenny smiled and hugged him "Defiantly"

"You and Dickie didn't have sex yet did you?"

"Dad" Jenny whined "Please"

"I'm just worried that's all, its my job as a dad" He gave her a kiss on the head.

"Why do you think you and mom adopted me in the first place?" Jenny whispered looking up at him.

Mark instantly felt bad bringing up what happened to her "I'm sorry sweetie"

"Don't be. If my…my biological dad didn't rape me then I wouldn't have fallen in your arms and I'm glad that you and mom are my adoptive parents"

Mark nodded and held her tighter "I love you" He whispered softly.

"I love you too no matter what"

"I'm glad to hear that"

"Don't worry when I do decide to have sex I'll tell mom I promise"

"Good. Now go get some sleep kiddo" He gave her a kiss on the cheek and let go of her.

"Goodnight" Jenny smiled at him and went up the stairs.

Mark lay down and knew it was only the twins left to tell which would be the hardest part since they were attached to him.

He got up and slowly went into Olivia's room and sat down by the bed and watched her sleep "I'm so sorry" He whispered quietly "I love you" He tried to fight his urge to fall asleep since he just wanted to watch her.

Jenny knocked on James's door and went in when she heard him accept. "Hey"

He was sitting up against the wall in his bed and staring blankly at the wall across him "What's up?"

She sat down by him and looked at the wall he was looking at "You heard about mom and dad?"

"Yea. It was harsh, mom even accepted to go on a date with this one guy that almost arrested me"

"Oh yea I heard"

"Your boyfriend?" James asked in a mocking voice.

"No. Sarah, her boyfriend who is your friend was with you and got arrested told her and she told me"

"Girls" James mumbled.

"Hey you men aren't as good, dad told me it's his fault"

"Same here" James nodded "After they divorce we are going to be so punished all the time cause he is more laid back then mom"

Jenny looked over at him "They won't divorce"

James looked at her "How do you know?"

"It's mom and dad were talking about Jimmy boy," She teased as she messed with his hair.

"I know but you should have seen how cold she was toward him, it looked like there was no chance anymore"

"That's why we have to meddle into moms date"

"No" James protested, "I'm not getting involved."

"Fine but when Lilly grows up without a full time dad you're going to be the one to blame"

James let out a deep breath and rolled his eyes "What do you have in mind?"

Jenny smiled and rested her head on his shoulder "Who ever that guy is that asked her on a date will pay"

"You're evil"

"Thank you" She smiled at him and gave him a kiss on the cheek "Sleep for tonight bro but tomorrow its party time" She went out of his room and went into her own.

James flopped down on his bed not believing they were the ones that were going to put their parents back together.
