A/N: Sorry for the lack of updates, I've been really busy lately, and had no time to update. I also got carried away writing a chapter of a new fic, but decided it will tie into this fan fic later down the line. I hope you enjoy this chapter, and as always, please review if you have the time.

I couldn't help but smile thinking about what Alex had said about us having kids, as I was driving to the women's shelter, all I could think about was me and Alex as parents. I felt her hand on my knee and heard her crisp voice in my ear. "Focus on driving you." she said with a beautiful smile.

I smiled too, "I am. I'm a brilliant driver." I felt Alex give my leg a squeeze.

"I know you are." she said softly. "Are you okay?"

I nodded a little thinking back to Lucy, "How can she be so hard and cold?" I asked.

"She's a street kid, looking after a six month old baby. She has to be hard to everything, on the outside at least."

"I suppose, I just find it hard to understand how a mother could leave their own baby, but to leave two. I just can't wrap my head around it."

"Are you thinking about Marni again?"

I felt a lump rise in my throat, "I still feel like I should have done something." I admitted.

"You know you can't do anything now to get her back, but you can put a stop to Lillian." Alex said smiling.

"Oh I will." I was determined to put a stop to Lillian and her human trafficking. I threw a right and pulled up outside the women's refuge. Alex and I walked in, I identified myself and soon had baby Callie in my arms. Alex put a car seat in the back of the Crown Vic, and together we made sure Callie was tucked in and safe. I got back in the drivers seat and turned to face Alex, "That felt..." I said trying to find the right words.

"Right." Alex said for me, spot on with how I felt.

"Yeah." I turned and checked on Callie, she was sleeping. I smiled and pulled away from the curb.

"I love that look in your eyes." Alex said softly.

"What look?"

"The parent look. You had it with Marni."

I smiled a little, "I've always wanted to be a mom." I admitted.

"I can tell." Alex said resting her head feeling tired.

I drove back to the one – six, got Callie out of the car and took her to see Lucy. Leaving her with Elliot, Alex and I made it our mission to find the two girls Marni had told us about. I had print outs of the girls faces from the bank, and thanks to their arrest records, I knew their local hangouts. Alex and I headed out to a cafe where the girls are known to go. And there they were sitting in the window. Fin and Munch pulled up behind us and went in. I couldn't risk being seen knowing Lillian had photos of me, and no doubt Alex by now.

We followed the girls for three hours before they lead us to the top of the garden space in Chelsea. I looked at Alex and she gave me a look that said she felt exactly the same way I did. Shocked that such a nice place would be home to such a low, disgusting event.

"We're going to need a plant here tonight." I said to Alex, Fin and Munch got into the back of my car.

"I'll go." Fin said. "I don't have any plans other than a TV dinner and reruns of CSI."

I nodded with a smile, "How do we get you in?" I said.

"Easy, I act like I've got an invite. Confidence is the invite." he said.

"So that's where I've been going wrong." Munch laughed.

"We need an idea of how many people are turning up tonight." Alex said looking at me.

"Fin can give us an estimation when he's in there. If we need more back up, we can arrange it." I said softly.

The evening rolled around quicker than I thought it would. All day I had been debating whether to confront Lillian but I knew I shouldn't. I couldn't risk messing tonight up. We needed this to nail her ass to the wall. We had the letter from Marni, and if everything went to plan we would stop a people trafficker. Alex and I were sat in the Crown Vic in Chelsea whilst Fin and Munch both decided to go into the building. Amazingly, they both went in, no questions asked, no problems.

Fin took a look around, Munch was off talking to some other guests. "It all seems pretty legit so far." he mumbled into his sleeve. "Got about twenty people here so far. No sign of the girls or Parks."

I looked at Alex who gave me the same look back, "Is it all men?" she asked.

"Pretty much, got a few girls scattered around, but mostly pervs in suits." Fin mumbled again. "I'm going to work the room." Fin set off and headed in the direction Munch was, he gave a nod at the men who turned their attention to him. "Gentlemen." he greeted. "Do you know what the turn out is likely to be tonight? I have a... prior arrangement." he said leading the conversation.

"Are you heading to Dallas tonight too?" one man asked.

"No, London. My flight leaves at three."

Munch stepped in, "You're going to see Driver tomorrow?"

"You know Driver? You must be well connected." Fin said with a smirk sounding very impressed.

One man looked at them both, "Tell me more about Driver."

"Who's asking?" Fin said getting defensive.

"A potential client." the man replied.

"Driver doesn't deal in small time." Fin said giving the stranger a look.

"I'm Lillian's wing man, I personally picked the girls for tonight. You like them, you let me know. We'll go from there."

"You'll be around all night?" Fin asked.

"Yeah, I'll be with Lillian in the booth." he said pointing. "There's twelve girls tonight, pick out a few, I'll give you a free ride before we ship them off." the man said with a smug smile.

"Sounds fair." Fin said, he looked at Munch. "How are you getting to London?"

"Business class." he responded.

"Sit with me tonight, you can catch a ride on my plane tomorrow. It's private." Fin said motioning to the bar. "Drink?"

Munch nodded, "I'll buy."

Alex and I looked at each other, I always knew Fin handled himself well, but tonight he was doing better than I'd ever given him credit for. "He's good." I said with a smile.

"The Driver story was a brilliant move." Alex said.

Through the static, Fin's voice appeared, "Ladies please, my ego... I won't be able to get my head out the door." he laughed as did Alex and I.

Alex sighed, "Twelve counts of kidnapping, reckless endangerment and in some cases rape and abuse. We've already got a good case."

"That's if the girls talk. Hopefully they will, but they've been tortured and taught talking has consequences." I told her, but she already knew.

"Liv you can make anyone talk to you. These girls will need you, there's no one else like you."

I smirked, "Now I know how Fin feels." I laughed, I picked up the radio, "Fin what time is this kicking off?" I asked.

"Ladies and gentlemen, I hope you enjoy the show." Lillian said, she sat down in her booth with the mystery man.

The first girl came out wearing nothing but her underwear. Then a further eleven girls were showed to the guests. Fin had to hide his disgust, as each girl was only known by a number. They were all shown off like animals, their age given, drug of owners choice and their trainers regime. Lillian stood back up and smiled.

"I can see that you've all enjoyed our girls tonight. We've raised enough money to go to Europe and bring back thirty more girls for your pleasure. I would like to thank all of you for coming, and I hope to see you at the next auction."

Fin gave a signal to Olivia, within seconds fifty arms officers were in the event room. Olivia took great pleasure in arresting Lillian Parks. She hauled her into the car, then drove to the one – six. Olivia put Lillian in the lock up and sat down with Alex.

"I bet that felt good." Alex said with a coffee in one hand and a smile on her face.

I nodded, "Good, verging on great. Do you think we have a case?"

Alex nodded taking a mouthful of coffee, "Yeah, we have Lillian on tape and we have the photos Munch took of the girls, and a video of her little speech. We'll nail her for this, don't worry."

"I'm not worried." I said with a yawn. "I'm going to take Lillian down for her blood test. I want her DNA on the record. Not a vile of blood and secrets."

"I'll come with you, you never know Liv, she might not be your mom."

I tried to smile, "If she is my mother, it means my whole life has been a lie, if this test proves she's not my mother, then I'm going to be wondering why the hell she did all this in the first place."

Alex looked at me, "If it turns out she's not, I think the only thing you can think is that she wanted to take you out of the force. Remove your focus so she could get away with everything she had planned." Alex sighed annoyed she couldn't get her words out, "I just mean that she must have thought you were a threat, if she takes you out of the equation, she stood a better chance of getting away with her plans."

I looked at Alex, "I know what you mean." I thought about what Alex had said but it didn't make it any easier, I felt that same confusion hitting me, it was the same feeling I'd had when I saw the baby photos of myself, sitting all perfectly lined up. Right there in perfect view.

I got up and headed to Lillian who was sat in the lock up, I walked her down to Warner who took Lillian's blood. Two uniformed officers took Lillian back to lock up, I looked at Warner and waited for her to tell me something about the blood. An hour later, she could only tell me one thing, but it was the one thing I had hoped for.

"The blood type is different." she said confidently, "The blood in the Vile is your mothers, the blood from the test is Lillian's." Warner handed me a sheet of paper. "Lillian's blood type is B negative, your mother's was O positive. She stole your mom's blood."

Those words were exactly what I wanted to hear, Lillian wasn't my mom, but that only left me one question; how the hell did she get my mom's blood?
