Hey guys so this is my AU with my own make up of the team from different seasons. Basically Munch is gone, Elliot hasn't left (yet) Amanda hasn't arrived (yet) and Nick is gone too. Fin is awesome, Elliot is brooding, Carisi is a hyperactive child, Liv is Sergeant, Cragen is still Captain and shit is about to go down.

btw I base all my law and police knowledge off of shows like this that I watch so if I get stuff wrong I'm sorry just try and go with it please?

Let's do this.

EDIT- MASSIVE TRIGGER WARNINGS FOR THIS STORY - CHILD ABUSE, UNDERAGE SEX, RAPE, CHILD PROSTITUTION.

16th Precinct 02/11/18

"Olivia! Got a live one, you and Elliot are up."

Cragen's voice came from the door to his office and Olivia lifted her head from where she had been filling out paperwork. She was already in motion, grabbing her jacket and gun as she asked

"Where?"

"A clinic on West 63rd. But you're not goin' there, Fin and Carisi are. Get Stabler, head to Bellevue the vic's there. Girl, 14, assaulted. Go, now."

"On it" was her response as she headed to the door meeting Elliot who was walking the opposite way carrying to cups of coffee.

"Turn around" she said as he frowned at her in confusion, taking one cup from his hand "It's coffee to go this morning. We gotta get to the hospital, I'll fill you in on the way."

Bellevue Hospital 02/11/18

"How is she?" Olivia asked the doctor as she, the doctor and Elliot walked through a set of double doors and down another hospital corridor.

"Not good, it was close but she'll live. Broken ribs punctured her right lung, arm fractures, wrist fractures, facial bruising and several deep cuts along her abdomen."

"Sexual assault?" asked Elliot his face as grim as it ever was.

"I believe so."

"You believe so?"

Sighing the doctor stopped and he turned to face the two detectives.

"She's traumatised. The nurses approached her about a rape kit and she almost went catatonic. She's not talking, won't give us consent to examine her for sexual assault, she barely let us treat her injuries and she was partially sedated at the time."

"Wait doc slow down. What do you mean partially?" said Elliot.

"They must have sedated her at the clinic and the effects began to wear off by the time she reached here."

"You mean she received medical attention before she came to the hospital?" asked Olivia and the doctor nodded.

"The ambulance picked her up from the clinic, they were already working on her when the paramedics arrived."

Grace and Mercy Clinic – West 63rd street – 02/11/18

"You the first on the scene?" asked Fin as he and Carisi approached a uniformed officer who was writing something in his notebook.

"Yeah. Officer Adam Craster, my partner, Officer Tailor is with CSU."

"Give us the run down. The hell happened here?" asked Fin, putting his hands in his pockets as the cold New York wind blew down the street.

"Easier to show you. How it started anyway."

"CCTV caught the whole thing" said Officer Craster as he showed Carisi and Fin into an office inside the clinic. When they were both inside he pressed play on the monitor in front of them.

"Dr Max Linden runs the clinic, he arrived at 6:45am."

They watched as the man who must be Linden walk into the main waiting room.

"Perp must have been waiting for him outside because about thirty seconds after he gets in…" Craster tailed off as Fin and Carisi watched the scene unfold.

The Doctor was checking his phone when a noise they couldn't hear made him turn to look at something out of view of the camera. Not out of view for long though as a hooded figure a lot smaller than the doctor, and with a scarf around their face came storming into view a gun aimed right at the doctors head.

"Doc surrenders, straight away they go back out the front" Craster paused as the doctor and the figure disappeared for a few moments "then this happens."

"Well that was unexpected" said Carisi, eyebrows raised.

"Bang goes my drug addict looking to score theory." Fin agreed.

The CCTV footage showed the doctor and the unknown figure reappeared but now the doctor was carrying a limp figure while the hooded perp kept the gun trained on him.

A girl.

Young.

Seemingly unconscious.

Craster paused the tape.

"They go back to exam room one and the camera looses them." He said.

"We need to talk to the Doc"

"He's through here."

The trio of cops walked through the hall into the waiting room where the doctor was sat talking to a female officer who Munch guessed was Craster's partner officer Tailor. Dr Linden must have been in his late forties to early fifties, with short cropped blonde hair and an athletic build. He stood up when Fin and Carisi approached.

"Dr Linden. 'm Detective Tutuola this is Detective Carisi with Special Victims Unit. Think you can walk us through what happened after you ended up in the exam room."

"I arrived early, I had some paper work to catch up on. I saw her outside but she was alone. She must have caught the door before the automatic lock engaged and come in behind me."

"Perp was female?"

"Definitely. She tried to hide it, lowered her voice and covered her face but it was definitely a girl. Young too, probably not much older than the patient. She made me go outside to the alley and that was when I saw the younger girl. The girl with the gun told me to take her inside and treat her. So I did. But she needed treatment beyond what I can do here. I told the older one that and she told me to call an ambulance and then she took off."

Fin gave the doctor a curious look.

"Don't mind me sayin' Doc, but you seem awful calm bout this."

"I was an army medic for three years. Guess I deal with stress better as a civilian than I do as a soldier."

At the questioning look from the Detectives the doctor explained

"I was discharged. Post Traumatic Stress. Mostly sound related, nightmares and flashbacks about missions and field surgeries that went bad. Couldn't hold my nerve in the field anymore. Guns don't scare me too much, I uh, I guess that's why I'm reasonably calm. Training and therapy combination, guess it did me some good after all."

"Is there anything else you can tell us about the girl with the gun. Anything about what she looked like or did she say anything else?"

"Only what I told Officer Tailor here. From what I could tell from her face and her voice she was Hispanic. Young. Wore black jeans and boots, grey hoodie. I uh, I'm afraid I cant tell you what kind of gun it was. Um, to be perfectly honest I tried not to look at it, didn't want to lose my head."

"Don't worry about that, our guys should be able to give us a basic idea when they see the footage." Carisi supplied.

As Carisi and Fin turned to leave, Linden called

"She called the younger girl Marls. Maybe short for Marley or Marlene?"

"Thanks Doc." Said Carisi.

"Detectives?"

Carisi and Fin turned once more just as they reached the door and the Doctor said with absolute surety

"She did something wrong I get that. But if she hadn't gotten her friend basic treatment when she did that girl – Marls – would have died. I think she was doing what she thought was best. I just thought you should know that."

Bellevue Hospital 02/11/18

"What have you got Fin?" Olivia asked as she stood in a corridor around the corner from the young girls room. Elliot had stepped away and was talking more to the girl's attending doctor when her phone had rung.

"Girl forces her way in, makes the Doc treat her friend at gunpoint. When he can't do any more she tells him to call an ambulance and runs off." Fin said down the phone before he sighed a little "Liv something just don't feel right about this. Half of me thinks our gun carryin' guardian was the one who beat the hell out of our vic."

"Well you could be right. We still don't know if she was raped but my money is on yes. If so, it's possible that our gun girl carried out the assault after the rape but…"

"But you just don't see it" Fin finished her sentence and Liv smiled to herself and it showed in her voice when she answered

"Mind reader" then the smile fell "But seriously Fin, the doctor said this girl was beat within an inch of her life and it was with the perp's bare hands. I'd want to check with Warner but doctor says based on his experience the strength required, it'd have to be a man or body building woman and-"

"And not some tiny ass skinny girl."

"Are you going to let me finish any of my own sentences today?"

"Not a chance Liv."

She couldn't help but smile a little again. Looking up, Olivia saw Elliot walking towards her with a grim look on his face.

"Gotta go Fin."

Olivia hung up and turned to face her partner who said in a voice that was full of false calm

"This guy really did a number on her. Doctor Anders over there thinks she's lucky to be alive."

"Any personal effects with her?"

"None. No ID, nothin' to tell us who she is."

Olivia opened her mouth to respond but paused when her phone buzzed. It was a text from Fin.

Girl called the vic Marls. Doc said it could have been Marley or Marlene?"

"She awake?" she asked as she put her phone away.

"Came round five minutes ago. Doctor says we can talk to her but tread carefully." Elliot answered and Olivia couldn't help but tease him a little by saying

"Well we all know treading carefully is your specialty El. We got a name. Partial name anyway."

Smirking at the look he shot her Olivia stepped round him and started walking, saying over her shoulder

"Come on then. Let's go talk to Marls."

Ta da!

Hope this is an ok start. I've never really had the confidence to write an SVU story before so i'd appreciate feedback even if it's constructive.

More action to come with an appearance of my favourite character. Think you can guess who it is?

More soon.
