Mark arrived at the house at 6 in the morning, since he finished a case and was supposed to have the day off. He walked in the house, Tommy was sleeping on the edge of the couch with one hand on the floor and his pillow on the ground. Mark smiled and shook his head. He picked up the pillow and placed Tommy's hand on the couch and covered him with the blanket. He started walking away but tripped over Tommy's converse.

"What the hell" Tommy mumbled and fell asleep again.

"Stupid shoes" Mark muttered rubbing his knee where he hit it. He heard the shower going and knew Olivia was taking a shower. He smiled and got up.

He went to their room to get the key of the bathroom that only they had after James locked himself inside by accident. He slowly unlocked the door and went in so she wouldn't hear him. He heard her singing and he tried so hard not to laugh hysterically.

He grabbed all of her clothes and threw them outside. He pulled out his phone that had a camera on it. He opened the doors slowly.

"Its easy loving cause your so beautiful" He sang out loud, she got startled and turned around and he took a picture of her and started hysterically.

"Mark!" She yelled closing the doors.

"Detective Benson sings in the shower, how cute" He mocked laughing.

"You better delete that picture or I'm going to kill you" She threatened smiling.

"I can blackmail you for sex now" He said smiling as he leaned on the wall.

"you wish, I can just cut you off completely and you know it" She said smiling.

"Do you think Elliot would want to know if his partner sings in the shower?"

"you better not tell him or I seriously will hurt you" she warned.

"I'm not scared of a detective who sings in the shower" He said smiling. She smiled and put water in her hand and opened the door and threw it on his crotch. He smiled and looked at his wet jeans.

"Nice, thank you, can I join you in that shower?" He asked smiling.

"Sure" she teased and grabbed him and pulled him in with his clothes on, she jumped out of the shower and turned off the hot water.

"Liv!" He shrieked as cold water hit him and he moved away. She grabbed his cell phone and took a picture of him.

"Touché my husband" She said smiling and wrapping a towel around herself.

"Your getting better at the whole prank thing, I'm so proud, but you haven't mastered it yet" He said turning off the water and smiling. She turned around where her clothes were sitting but they were gone.

"Jerk" Olivia said under her breath and smiled. He smiled and came out of the shower with his clothes completely soaked.

"I'm still the master" He said as he wrapped his arms around her,

"yes you are, you win, we even with the pictures?" She asked leaning her head on his shoulder and looked up at him.

"Give me a kiss and we'll be even" He said smiling. She smiled and kissed him. He pushed her up against the wall and kept on kissing her. He grabbed her towel and loosened it.

"I have to go to work" She said holding the towel up.

"no you don't" He said kissing her wet neck.

"Yes I do, next time, I promise, I have to go" She said pulling away from him. He pulled her closer and kissed her again. She smiled and rubbed her leg against his groin on purpose to tease him. He let out a small gasp and bit his lip.

"You are such a tease I hate you," he said smiling.

"I know," she said smiling and running her hand down his chest, she let her hand slide under his belt but then pulled it out on purpose, he let out a gasp and smiled. "Have to go" She whispered and went out the door.

"god I love that woman" Mark said smiling and leaning on the wall.

Olivia went into their room smiling, she thought it was so cute how he gets turned on easily. She smiled at herself for teasing him like that. She opened her closet and pulled out jeans and a pink sweater with white strips.

Mark came in smiling, he pulled off all his wet clothes and only had boxers on.

"Hi, you have fun with your erection?" She teased smiling standing in their room with only panties and a bra on.

"no, I need you for that, do you have to tease me like that? Its not nice" he said smiling and checking her out.

"It's fun, your such a guy when it comes to turning you on, all I have to do is brush up against it and you're hooked" She said smiling as she pulled on her jeans.

"Well your hot, that's why" he said walking over to her.

"no sex now, Tommy is in the next room and I have to get to work" Olivia said smiling as he put his hands on her waist. Mark pouted and give her a puppy face which always made her laugh cause he looked adorable when he did it.

"It can be semi-final" he suggested smiling.

"No, I have to go, sorry" she said smiling and grabbed her sweater, he went behind and squeezed her ass which made he jump up "stop doing that" She said smiling.

"it's a turn on for you, I know that, why do you think I do it" He pointed out smiling as he put his hands in her back pocket and rested his chin on her shoulder.

"Well you wont get any so stop trying" she said smiling kissing him on the forehead.

"I love you liv" he said looking at the sweater she was holding up.

"I love you too Mark" she said smiling as she got ready to put on the sweater. He smiled and kissed her on the cheek. He pulled out his hands out of her pockets and flopped down on the bed. She smiled and put on her sweater.

"What should I do with Tommy? Cause I know he doesn't want to go back to his mom's" Mark asked looking at her.

"oh about that…um let him stay here for a while, he doesn't want to go back to that place" Olivia answered as she grabbed some make-up.

"Do you know something I don't?" he asked with a suspicious look.

"yea, he talked to me last night about what happened"

"What happened?"

"um…well…I don't really want to tell you…"

"Liv just tell me, what happened?" He cut her off, watching her get ready.

"His mom's boyfriend was abusing his own daughter and Tommy saw him and hit him with his skateboard, and he was scared that he might try it on him so he came here" Olivia said leaning on the dresser looking at Mark's shocked expression.

"Liv?" Mark said looking at his nightstand.

"Yea?"

"where are those keys I put here last night?" Mark asked noticing Tommy's car keys were not there.

"I don't know, wait…its been too quiet" Olivia said and rushed for the door. "Mark he's gone" She yelled out looking at the empty couch.

"Damn it, why don't you go to work and I'm going to try and find him" Mark suggested as he pulled on his jeans.

"Where are you going to look for him, he has a car, he can be anywhere?" Olivia asked watching him grab his holster and badge.

"He has an old girlfriend near here, so maybe he went to see her, I'll call you if I find him, Bye" Mark said giving her a kiss and pulling on his shirt and going out the door.

It was 3 in the afternoon, Mark searched all morning for him, at friends houses, old girlfriends. He finally decided to go to his house in Jersey to check if he was there. He got to the house at 4, he saw Tommy's car in the parking lot. He got out of the car and went inside the house since it was unlocked.

Tommy was on the ground crying with a small girl in his lap also crying, he was completely covered in blood and his head was bleeding on the side. A man who was way bigger then Mark was on the floor with a broken skateboard by his head and a broken whiskey bottle. He was covered in blood and his head was completely cut up. Mark looked at the man and at Tommy, he kneeled down and checked the man's pulse but there wasn't one to be found. Mark looked at Tommy realizing he killed him.

"He attacked me" Tommy choked through the tears as the small girl sobbed in his chest.

"Where's your mom?" Mark asked looking at him. Tommy just shrugged and wiped his tear and hugged the girl.

"Ok, lets go," Mark said picking up the girl so she wouldn't look at her dead father. Tommy got up and followed him outside. Mark called for an ambulance to the house and drove the kids to the only place he knew they were supposed to be at that moment. SVU Manhattan.
