The girl cried in Mark's arms all the way up and Tommy just stared at the ground as all three walked through the hallway of the precinct, everyone stared at them since they recognized Mark.

Olivia, Elliot, Fin, John and Cragen were standing around a board talking about a new case they just started. John was the first to see Mark. Everyone else looked up at him.

"What happened?" Olivia asked walking over toward them.

"I'll tell you later, take them somewhere" Mark whispered trying to settle the crying girl. Olivia took her in her arms but she reached out for Tommy. Tommy took her.

"Jenny, this is my friend Olivia, why don't you go with her ok?" Tommy said looking at the small girl. The girl just nodded and let Olivia take her.

"Lets get that cut fixed up ok?" Mark said putting his arm around Tommy's shoulder.

"I killed him," Tommy said to no one in particular and just stared at the ground.

"It was self defense Tommy, go with my friend John and he will get you some ice for your face ok?" Mark said patting him on the shoulder and looked up at John who just nodded. Tommy nodded and let John lead him away from the bullpen.

"What's going on?" Elliot asked.

"Tommy is my nephew, he caught his mom's boyfriend abusing his own daughter last night and he hit him with his skateboard and came to our house to spend the night. He sneaked out this morning and when I finally found him at his house, he killed to mom's boyfriend with a skateboard and a bottle of whiskey, I called Jersey cops and they should be there by now" Mark answered as Olivia came out of the child interrogation room.

"What happened?" Olivia asked coming over to Mark.

"Tommy killed the boyfriend with a skateboard and whiskey bottle at his house, he said that he attacked him" Mark answered running his hand through his hair.

"The girl isn't saying anything, she keeps asking for Tommy" Olivia told everyone.

John and Tommy came back talking about a theory. Tommy holding an ice pack to his head and arguing with John.

"Dude, your old you don't know what your talking about" Tommy said looking at John.

"I have more experience cause I'm older and that's why Guns & Roses will always be the best band" John said smirking.

"Your nuts man, AC/DC rules, you need to catch up on some music, trust me I know music and Guns & Roses is not the greatest band" Tommy said rolling his eyes.

Everyone watched them and smiled, glad John got Tommy to think about something else.

"Hey Tommy, we need to talk to you about what happened, are you ok with that?" Olivia asked gently placing her hand on his shoulder.

"Yea, sure, how's Jenny?" Tommy asked looking up at her.

"She's still crying and she's asking for you" Olivia told him.

"You want me to talk to her, so she would talk to you?" Tommy asked.

"Yea, come on" Olivia said leading him into the children interrogation room.

"Tommy!" The girl yelled out as he came in and gave him a hug.

"Hi Jenny, this is my good friend Olivia" Tommy said pointing at Olivia.

"Hi Jenny" Olivia said smiling as she sat across her.

"Hi" Jenny said quietly.

"I need you to do something for me, you need to tell Olivia what happened the last night and how my dumb skateboard got broken" Tommy said with a smirk, Jenny smiled a little and nodded.

All the guys stood behind the mirror and watched.

"He will make a great detective one day" Cragen said and looked over at Mark.

"Yea, he spend a lot of time with me when I was in homicide, so he knows a lot about this stuff" Mark said smiling proudly watching his nephew.

"Can you stay with me?" Jenny pleaded looking up at Tommy.

"I have to go talk to Olivia's friend, but I'll come to see you after, you stay here and talk to Olivia, Ok?" Tommy offered.

"Olivia can Tommy stay please?" Jenny begged looking at Olivia.

"If he wants" Olivia answered. Jenny looked at Tommy with pleading eyes, he didn't want to hear any of it but he sat down so Jenny would talk to Olivia.

"Well last night I was in my room and…" Jenny started but stopped as a tear rolled down her cheek.

"It's ok Jenny, I'm here" Tommy reassured her and wiped her tear and took her small hand. Jenny just nodded and held his hand tighter.

"My daddy came in and he hurt me…" Jenny said getting up "Here" she said pointing to her privates. She sat down and held Tommy's hand. Olivia looked at Tommy and saw he didn't want to be in the room listening, he just sat there staring at the ground and holding her small hand.

"Then what happened?" Olivia asked gently looking at Jenny.

"I started screaming because daddy was hurting me and I got scared, Tommy came in and took his skateboard and hit daddy over the head…and then Daddy punched Tommy, Cindy came in and hit Tommy for making Daddy bleed…Tommy hit daddy over the head again and his skateboard broke. Tommy ran out of the room and grabbed his keys, daddy and Cindy didn't see him but I did, he sneaked out of his window and drove away" Jenny finished, by now she was crying and hugging Tommy, Tommy was just starring at the ground with his eyes full of tears.

"Ok, Jenny why don't we let Tommy go and talk about what happened and I can talk to you, is that ok?" Olivia asked gently. Jenny nodded and let go of Tommy. Tommy wiped his eyes and walked out of the room.

"Tommy, this is Elliot he will talk to you ok?" Mark told Tommy when he came out of the room.

"Sure" Tommy answered and let Elliot lead him to a room.

Tommy went into the room and sat down and Elliot followed him. Mark and Cragen watched from his office. Fin and John went to the crime scene already.

"You want anything to drink?" Elliot asked closing the door.

"No, I'm fine, lets just get my statement so I can go" Tommy answered letting out a deep breath.

"Ok, sure, lets start when you left Mark's house" Elliot suggested. Tommy just nodded.

"Mark took my car keys and when he went to work I sneaked in his room while Olivia was sleeping and took them, I waited for him to come home until I sneaked out, when he came home he went to the bedroom and I sneaked out. I felt bad for leaving Jenny there alone with that stupid asshole so I went back to get her." Tommy said and took a deep breath.

"What about your mom?" Elliot asked reading the notes Mark gave him earlier.

"I really didn't care cause she was high and drunk the night before, cause I knew that she was on Ivan's side on everything and he wouldn't hurt her. So I had to get Jenny out before they got drunk and did something to her"

"What happened when you got there?"

"Ivan was drunk, I tried to sneak in and get Jenny so no one would notice I was there but he saw me and hit me with the bottle he was holding. Jenny was standing right there so I didn't want to fight cause she was watching me. I grabbed her and tried to make a run for it and the next thing I knew I felt my old skateboard hit me in the back, luckily he was drunk and didn't have full force, Jenny started crying which got me pissed, I grabbed his whiskey bottle and hit him over the head. He started bleeding…and grabbed my…well my privates. I grabbed my skateboard and started hitting him, until he let go. When he did he called Jenny a bitch, and me a bastard cause my dad isn't around, so that got me mad and I just lost it…I hit him harder and faster until I got exhausted and my skateboard was in half and I stopped, when I finally realized what I did, I checked his pulse and he was gone." Tommy finished looking at the ground.

"What time was it when you realized you killed him?" Elliot asked amazed what this kid did.

"Around 3:30 or 3:45 around there" Tommy answered.

"Ok, why don't you stay here while I talk to Mark ok?" Elliot asked getting up. Tommy just nodded. Elliot went toward the door.

"Ivan has a rap sheet," Tommy said looking at the ground. Elliot stopped and turned around.

"What? How do you know?" He asked coming over to the table.

"When Olivia fell asleep I went on their computer and looked him up, you can find this stuff easily on the internet" Tommy answered shrugging.

"Ok, I'll check that out, thanks Tommy"

"His last name is Martinez, used to be Connelly but he changed it after Jenny was born and her mother died cause of a overdose, he changed it so he could keep Jenny and no one would know he was in jail"

"How do you know all of this?" Elliot asked looking at him. Tommy looked up at him.

"I eavesdrop," Tommy answered with a smirk. Elliot smirked and left the room.

Olivia joined Mark and Cragen behind the mirror and heard the whole conversation.

"Lets find Ivan Connelly in the system" Cragen suggested. Olivia nodded and left the room. Mark just starred at Tommy through the window.

"That kid has to be one of the smartest sixteen year-olds" Elliot said coming in.

"Lets call John and Munch see if they have anything to back up the self defense," Cragen said, Elliot nodded and pulled out his cell phone and left the room.

"Are you ok?" Cragen asked looking at Mark.

"Yea, I'm fine, I'm going to go see what liv has" Mark said heading to the door.

"Mark?" Cragen called after him.

"Yea?" Mark said turning around.

"I know this is personal so just watch your moves, ok?" Cragen warned.

"I know" Mark said nodding and leaving the room.

"Two years in jail for assault, got out 6 years ago" Olivia said printing out the paper.

"Where the hell is he?" A woman yelled coming in the bullpen. Mark just rolled his eyes knowing it was Cindy.

"I'm Detective Benson, who are you looking for?" Olivia asked getting up, knowing it was Cindy by Mark's expression.

"Mark knows," Cindy said angrily going up to Mark "Where the hell is Tommy?" She yelled. By this time Cragen came out and Elliot got off the phone and they just watched.

"Why do you care?" Mark said starring at her.

"Because he is my god damn son, and he killed my boyfriend, I want to see him now!" Cindy yelled getting in Mark's face.

"Why you want to protect another fucking boyfriend?" Tommy yelled coming out of the room.

"Tommy go in the room" Mark instructed, Tommy ignored him and went to his mother and got in between Mark and Cindy.

"You stupid bastard you killed him!" Cindy yelled and went to swing at Tommy. Mark grabbed her hand and went in front of Tommy.

"You lay one hand on him, I swear to god that will be the last thing you do" Mark threatened in a low voice holding her wrist. Olivia saw he was getting pissed and he might do something he would regret. Elliot and Cragen got the same feeling and walked behind Mark.

"Mark, go take Tommy in the room" Olivia said getting in front of Mark, and gently pushing him away. Mark looked at her and let go of Cindy's wrist.

"Is this your fucking pussy Mark?" Cindy yelled out, Cragen and Eliot grabbed Mark cause they knew he gets protective Olivia.

"Stupid bitch" Mark muttered as Elliot and Cragen let go of him so he can walk away. Cindy grabbed a stapler that was on the desk and before Olivia could react she threw it and hit Mark in the head. He fell down and his head started bleeding.

"You are under arrest for assaulting a Federal Agent" Olivia said grabbing Cindy and putting the cuffs on her and twisting her wrist a little on purpose.

"Hey you want me to read you your rights?" Tommy asked smirking at Cindy, Olivia smirked and let Elliot take her to a cell.

"Are you ok?" Olivia said kneeling down by Mark who was holding his head.

"Yea, get me a napkin or something" Mark groaned as the back of his head bled. Olivia got up and grabbed a towel she had on her desk and handed it to him.

"You want us to call you a paramedic or something?" Cragen offered.

"No, I'm fine" Mark said getting up and holding the towel to the back of his head.

"Tommy why don't you go in the room where Jenny is" Olivia suggested looking at Tommy, he nodded and left.

"I hate that stupid bitch," Mark muttered as he sat down in Olivia's chair.

"Let me see" Olivia said coming behind him to look at his injury.

"It's not that bad" Mark said moving the bloody towel away.

"You want ice?" Cragen asked.

"Sure" Mark muttered putting the towel back. Cragen nodded and left to get an ice pack.

"You sure you don't need stitching?" Olivia asked stroking Mark's shoulder.

"No I'm fine, you ok?" He asked looking up at her.

"I'm fine," She said with a smirk.

"I want that kid's autograph" John yelled out coming into the squad room.

"Why?" Olivia asked staring at him as she sat on her desk.

"This guy had to be at least 300 pounds, and about 6'3 and the kid killed him, he has some crazy ass rage" Fin answered smirking and sitting down on his chair.

"What happened to Marky?" John asked sitting down and looking at Mark.

"liv probably beat him up" Fin offered smiling. Mark and Olivia just rolled their eyes.

"Tommy's mom came and hit him with a stapler" Olivia corrected him.

"Ouch, Marky you're so lucky I got Olivia not to keep a baseball bat by her desk" John said smirking. Mark and Olivia smiled.

"I'm going to go check on Jenny and Tommy, I'll be right back" Olivia said getting off her desk and going to the room.

"Self defense?" Mark asked looking at John and Fin.

"Yea, were calling it like we see it" Fin answered.

"Yup, but that kid has rage" John answered.

"Well, it comes in handy at times like these" Mark said smiling.

"It's self defense captain" Fin said as Cragen came in carrying an ice pack.

"Ok, lets do the paper work and resume with our case" Cragen said looking at the detectives, they nodded and sat at their computers "Mark can you come in my office for a second?" Cragen asked giving the ice to Mark, Mark nodded and got up and followed him.

"What's up?" Mark asked as he closed the door of the office.

"When I went to get you the ice pack, I looked up Ivan and Jenny, Jenny's mom died and well Ivan is dead, so I want to suggest to you and this is of course a suggestion you have to talk to Olivia first but maybe you guys should take her tonight since she wants Tommy near her and I don't want to put her in ACS custody right away" Cragen suggested as he sat down behind his desk.

"Yea, I'll talk to liv, even though I know her answer already, thanks captain" Mark said with a smirk.

"Sure, why don't you go pull Olivia out of the room and talk to her and go home to get these kids some rest" Cragen said getting up.

"Sure, thanks" Mark said opening the door. Cragen nodded and followed him outside.

Mark went to get Olivia out of the room and talk to her. Tommy came out and sat with Fin and Munch.

"You got some rage kid" John said typing on his computer.

"That's what happens when you spend time with Mark" Tommy said smirking.

"I know what you mean" John said smirking. Tommy just smiled.

"Guys check her out" Tommy whispered to John and Fin, they both looked up and smiled when they saw Tommy checking out Casey.

"Novak?" Fin asked with a smirk.

"What ever you want to call her, she is hot" Tommy said watching Casey talk to Elliot.

"Casey Novak, she's the ADA, also your Uncle's and Olivia's friend and she hangs out with them sometimes" John told him.

"Well I'm sleeping on their couch from now on, god damn Mark he gets a hot wife and a hot friend" Tommy said smiling still checking out Casey. Fin and John looked at each other and smiled.

"Give you ten bucks to go and flirt with her" John offered smirking.

"You think I wont, she is a redhead and smoking hot, lets see the ten" Tommy challenged. John pulled out a 5 and looked at Fin who rolled his eyes and pulled out a 5.

"You flirt with her its all yours" Fin said smiling.

"Your on" Tommy said getting up and walking toward Casey and Elliot.

"This is going to be good" Fin said smiling, John smiled and they both watched.

"Casey right?" Tommy said going up to Casey, she looked at him and then at Elliot.

"Mark's nephew" Elliot said and looked at John and Fin who were trying not to laugh and smirked knowing they were pulling a prank on her "I'll be back" Elliot said walking away and sitting next to Fin and then all three watched smiling.

"Yea, how did you know my name?" Casey asked smirking at the teenager.

"For you I have resources, you have very pretty lips Casey" Tommy said smiling, Casey lifted one eyebrow and looked at him.

"Thanks I guess, um…where's your uncle?" Casey asked nervously.

"You don't need Mark now, you got me, name is Tommy by the way," He said smiling, Casey gave him a look.

"Ok, Tommy well um…way don't you go talk to Mark" Casey suggested.

"No reason to turn me down, I like redheads, their feisty it's a turn on, plus you're the ADA so you must be very feisty which I like" Tommy said with a charming smile. Casey's mouth dropped and she just stared at the 16 year-old. At this all three detectives started laughing hysterically. Casey looked at them and figured out they were messing with her.

"You just earned ten Tommy, nicely done" Fin said holding the money up.

"I do like redheads, but I also like green" Tommy said smiling and taking the money.

"You guys are so dead, you had a kid hit on me, how mature are you" Casey said rolling her eyes.

"I got a car, does that help the situation?" Tommy asked smiling as he sat down on a desk.

"You are exactly like your uncle, and no it doesn't since you cant even drink legally yet" Casey said rolling her eyes.

"She is feisty" Tommy said smiling, all three guys started laughing hysterically.

"Shut up" Casey mumbled smiling. Everyone smiled. Olivia and Mark came into the bullpen.

"Mark you just missed the best thing in the world" Elliot said smiling.

"What?" Mark asked looking at all their smiles.

"Tommy just hit on Casey," Fin answered smiling.

"and I missed it, damn, you guys should have recorded something like that, you know I get my amusement from her misery" Mark said smiling. Casey smiled and hit him on the shoulder "and you wonder why you're single" Mark said rubbing his shoulder.

"Jackass" Casey said under her breath and smiled.

"Leave Casey alone" Olivia said smiling as she sat down.

"Do I have to? Cause she is hot" Tommy said smiling, Casey just raised an eyebrow and looked at him. "Well you are" Tommy said shrugging.

"Poor Casey, gets hit on by 16 year old but never anybody she can legally date" Mark teased smiling.

"Shut up Mark" Casey said giving him a look.

"Relax, you know I love you like my own sister does that make you feel better?" Mark asked smiling.

"Maybe," Casey admitted shrugging with a smile.

"I hope you're happy," Mark said mockingly putting his hand around her shoulder.

"I hope you trip and fall," Casey said smiling.

"I take it back, I hope you're miserable" Mark said smiling and taking his hand off her shoulder. Casey smiled and rolled her eyes.

"Ok, Brady Bunch over there, lets finish this shall we?" Olivia asked smiling and getting up.

"Yea lets go," Mark said getting up "bye Marsha" Mark said smiling and looking at Casey.

"Bye Peter" She said smiling. Everyone smiled and rolled their eyes.

"Tommy why don't you come with us to talk to Jenny" Olivia suggested, Tommy nodded and followed them.

They came out a couple of minutes later with Jenny in Tommy's arms ready to spend the night at their house.

"Why don't you go home so they can get some rest and I'll see you there cause we have to finish this case, ok?" Olivia said to Mark.

"Sure, call me later ok?"

"Sure, love you"

"You too" Mark said giving her a kiss on the cheek before leading the kids out to the car.

Olivia got home at 12 that night, James was sleeping on the couch across from Tommy and Jenny was in James room sleeping. She went into her room and Mark fell asleep in his jeans with a case folder on his chest. Olivia smiled since she noticed he does that a lot when they first started living together. She picked up the file and placed on his dresser.

"Hey you" He said sleepily rubbing his eyes.

"Hi, you fell asleep looking at a file again" She said smiling as she took off her shirt to get ready for bed.

"Oh that's fine, not important file anyway, how was work?" He asked watching her.

"You were there for half of it, but the other half was fine, mostly witness statements and security footage we went over" Olivia answered putting on one of Mark's shirts and unhooking her bra under it.

"You need help with that bra?" He asked smiling.

"No, I think I can handle it" She said smiling taking off the bra.

"How about those Jeans? I'll help if you want," He asked smiling.

"Why don't you take off your jeans and get ready for bed?" She said smiling as she unbuttoned her jeans.

"Were undressing me first, ok, I'll take that" He said smiling getting up.

"Your undressing yourself, to go to bed and sleep" She replied smiling as she took off her jeans and sat on the bed.

"I think I might need help," He said with a smirk walking over to her.

"Your such a loser, that's a bad line" She teased smiling up at him. He smiled and walked over to her and stood in between her legs.

"A little help or what?"

"I need to teach you how to flirt better" She said smiling unzipping his jeans, he smiled and kissed her on the cheek, she rolled her eyes and got in bed. He just smiled at her and took off his jeans and got in bed with his boxers.

"This is a anniversary we won't forget" Mark said moving closer to her and wrapping his arm around her stomach.

"I know, by the way what's with the sleeping situation out there?" She asked putting her hands over his.

"James wanted to hang out with Tommy and Jenny didn't care so I figured it would be easier for her to have her own bed tonight and not sleep on the couch" Mark answered moving her hair behind her ears and giving her a kiss on the cheek, Olivia smiled and moved closer to him.

"You working tomorrow?"

"Yea, have to be there at 7, you?"

"Yea, how's your head?"

"Its ok, but it could be better" He said smiling and moving his hand from her stomach to her breast.

"No, your head is as good as it will get" She said smiling and playfully hitting his hand.

"Fine, you got a present and sex from the best looking man in the bureau that's not fair" He said doing a puppy face and gently massaging her breast over her shirt.

"No, I'm tired, go away" She said smiling removing his hand from her.

"Fine, but I want sex in the shower next time" He said smiling placing his hand on her waist.

"You always want things you cant get, 5 minute make out session deal?" She asked smiling.

"10 minute?" He negotiated

"Seven?" She offered.

"Deal" He settled kissing her on the cheek.

"How did your dorky self get me?" She teased smiling.

"Geeks just have a way with sexy women like you, were smooth and you fell head over heels when you saw me and don't even try to lie" He said smiling pulling her closer to him.

"Ok maybe I did, that's because your cute and funny, otherwise, you're a dork" She teased smiling placing her hands over his.

"I know I'm a dork, but you had my kid so you're a dork for having sex with me, by the way amazing sex" He said smiling. She started laughing.

"Ok were both dorks fine, but we are hot dorks"

"Yes we are, love you" He said smiling giving her a kiss.

"Love you too, goodnight" She said giving him a kiss.

"Goodnight" He whispered and held her in his arms.

Mark held her the whole night cause he couldn't sleep at all. He looked up at the clock, it was three in the morning and he still couldn't sleep.

"Liv are you awake?" He whispered.

"I am now, what do you want?" She groaned cause he woke her up.

"I can't sleep" He answered in a low voice.

"Why?" She mumbled her eyes still closed.

"I don't know," he answered.

"You thought I might know so you woke me up?" She mumbled.

"Sorry, I just cant sleep, I keep thinking about Tommy and Jenny" he answered. She turned around to face him and opened her eyes.

"They are safe now, you don't need to worry" She told him placing her hands on his cheek.

"I know, but I feel so bad for what happened, if I came earlier to Jersey, Tommy wouldn't have killed him"

"And something bad might have happened to Jenny, you cant blame yourself for what happened, Tommy defended himself and Jenny, you cant think what could have happened if you were there,"

"Yea I know, but I mean it was her father, Tommy killed him and now she doesn't have family, how the hell can her father do that to her?"

"I don't know baby, but you are an awesome father and an amazing husband, and a great uncle, I don't want you to worry about any of this stuff ok?" She said giving him a kiss.

"Ok, thanks, sorry for waking you up" he said hugging her.

"Don't apologize, its fine, plus I like it when we talk in the middle of the night like this" She said smiling kissing him on the cheek. He smiled and returned the kiss. She turned around so his hands were around her stomach again.

"I love you Olivia" He whispered softly in her ear. She smiled.

"I love you too Mark" She whispered back and placed her hands over his. He smiled and held her closer. They both fell asleep in that position, holding each other and not letting go.
