Chapter 17

Olivia ran from the living room and down the corridor to their son's room, as Elliot called 911 for an ambulance. He was in the middle of the call when Olivia ran back into the room.

"El," she said. Elliot looked over to her and knew straight away something was wrong.

"Liv, what is it?" he asked her as she walked towards him.

"He…. He isn't here," she said tears running down her face.

"What do you mean he isn't there?"

"He's gone…. Someone has taken him."

"Stay with the girls," he told her as he jumped to his feet and ran to Liam's room. He stared down into the empty cot as he pulled his phone back out his pocket.

"Hey El what's up?" asked Fin, Elliot could tell he had woke him up.

"Liam has been taken, he's gone. The girls ….were waiting for an ambulance," he said talking fast into the phone as tears flowed down his cheeks as he looked into the empty cot and picked up the small teddy bear Eli had given him and put it in his coat pocket.

"El what the hell do you mean Liam is gone?"

"Someone has taken him."

Fin jumped out of bed and pulled on his clothes. "I'm on my way man," he told Elliot. Elliot just nodded and hung up the phone, as he walked back to Olivia and his girls.

He dropped to his knees and put his arm around Olivia "Fin is on his way," he said to her as he looked down at Maureen and Kathleen, Olivia had finished untying their arms and legs.

"Who would do this El, who would take our baby?" she cried as Elliot pulled her to him.

"I don't know baby, but when I find the fucker he or she is dead. No body hurts my family…..Nobody," he said hugging her as she cried.

"Mmmmm…Dad," mumbled Kathleen, struggling to open her eyes. Elliot let go of Olivia and reached out to his daughter and stopped her from trying to sit up.

"Don't try and move sweetheart," he told her. "Help is on the way," he said pushing her hair out of her face.

"Oh god….. Spud," she said panic in her voice. "Where is he?"

Elliot looked at Olivia and then back to Kathleen. "We don't know Kat," he said "We need you to tell us what happened." He heard Maureen groaning and Olivia moved to her side and stroked her face to sooth and comfort her.

"We….we ordered pizza….it was late. It came then….. Then, there was another knock; we thought it was the pizza guy back. I opened the door and this guy….he was just stood there….."

"Who was he? Did you recognise him?"

Kathleen shook her head and started to cry. "He said he was here for his son… then he punched me," she said shaking. "I remember hearing Maureen scream….. He grabbed my hair and banged my head off the wall," she sobbed as she lifted her hand to her head. "That's all I remember, I'm so sorry daddy," she cried.

"It's okay baby," he told her leaning down and kissing her, "It's okay, you have nothing to be sorry for."

"Is…..is Maureen okay?"

"She is starting to come around," he told her as the paramedics came into the room.

Elliot and Olivia stood to one side as they got to work on the girl's; Elliot wrapped his arm around Olivia's waist.

"Liv, there is only one person I can think of who would think Spud is his."

"Yeah I know," she said her body shaking. "I just can't think why he would do this, unless he is back on the drink and drugs."

Elliot's eyes left Olivia as Fin ran into the room followed by Nick. They both looked around as they went to Elliot and Olivia.

"What the hell happened?" asked Fin.

"We think it was Brian," said Olivia.

"Cassidy… nobody has seen him for months, the last I heard Tucker said he was rehab that was 5 month ago. Why the hell would he come back and take Spud?" asked Fin.

"We don't know, but were sure it's him."

As much as Elliot didn't want to leave Olivia he went with the girls to the hospital as Olivia told Fin and Nick everything she knew. Fin called in CSU, as door to doors were carried out. Nick put the alert out to all units. Once Olivia had told Fin everything she knew Nick took her down to the hospital.

"Liv, why you so sure it was Cassidy?" he asked her as they drove through the city.

"Who else would think that Liam was his baby?"

Without looking at her he asked "Is there any chance Cassidy could be the father and not Elliot?"

Olivia shook her head. "Elliot is Liam's father you only have to look at him to know that," she said staring out the window of the car. "Plus I never had sex with Cassidy….. Not since before Lewis. There was only Elliot."

Nick nodded "Sorry but it had to be asked," he said to her.

"Yeah I know," she said wiping her eyes. Nick reached over and took her hand.

"We will get him back Liv, if Cassidy has him we will find him."

Olivia just nodded and carried on staring out the window.

Olivia walked down the hospital corridor towards Elliot with Nick. Elliot was stood up his back resting against the wall his head dropped forward.

"El," said Olivia as she got close to him. Elliot lifted his head and looked at her, his eyes red from crying. He opened his arms to her and she walked into them as he pulled her to him and held her tight.

"How are the girls?" she asked him as he held her.

"They're both gonna be okay. They both needed stitches and have a concussion. They need to stay in for a couple of days."

"Have you called Kathy?"

"Yeah she is on her way up. She is at her moms, visiting."

He pulled back and cupped her face in his hands as he dropped his forehead to hers. "We will find him," he told her. "We will get our little boy home, I promise you."

Olivia nodded. "Fin has everyone on this."

"As soon as Kathy arrives we will go to the station and help. I know there isn't much we are allowed to do but I can't just sit back and do nothing."

"Okay," she said as he pulled her back into his arms.

"I love you Liv," he said as tears flowed from his eyes again.

"I love you to," she replied as her tears fell on his shoulder and she held him tight.

Nick stood and watched them and felt his phone vibrating in his pocket. He took it out and answered. "Hey Fin, any news?" he asked him.

"Yeah, Cassidy checked himself out of rehab 3 month ago. I sent guys to his and Olivia's old apartment. They said the place was a mess. Empty bottles of drink of everywhere and used needles."

"Jesus Christ," said Nick.

"That's not the worst part. They also found photos of Liv everywhere; he has been watching her since before Liam was born. It looks like Liv and Elliot's suspicions where right."

"Well if he has taken Liam and he isn't at his apartment where else could he have gone?"

"Don't know Amanda is checking his bank accounts and looking for any other property. I need you to ask Liv if she knows of any other places he might go? And show Cassidy's photo to Kathleen and Maureen see if the can ID him."

"Okay will do. They are waiting for Kathy to arrive then they are coming down to the station."

"Okay man; give me a call if you get anything."

Xxxxxxxxxxxxxxxx

Elliot and Olivia drove in silence to the station both deep in thought. Elliot parked the car and turned the engine off plunging them into silence, as they both just sat there.

"This is all my fault," said Olivia quietly.

"Why would you say that?"

"I'm not meant to be happy, look at my life nothing has ever gone right for me," she said looking down at the ring on her finger. "I screw everything up. Everyone around me ends up hurt…. I mean we weren't back together long and some psycho took you to get at me, and almost killed you….your daughters are in hospital because my ex-boyfriend has totally lost it and stolen our son… you should have stayed away, I should never have let you in. This is why I don't let people in."

Before Elliot could say anything she opened the car door and climbed out. He quickly grabbed the keys and got out the car running after her.

"Liv stop!" he yelled at her, running up behind her. "I said fucking stop," he grabbed her arm to stop her walking and spun her round to face him. "I won't let you do this," he said pulling her to him. "None of this is your fault, none of it," he told her pulling her into his arms. She tried to push him away but he was too strong for her.

"I should have been there for him, I should never have left him," she cried as she tried to push him away. "I left him alone and look what happened, I'm not meant to be a mother. I knew I couldn't do this."

Elliot kept his arms around her as she cried and tried to break free from him. Her body shaking as she cried. "I should never have been a Mom," she sobbed. Elliot felt his own tears on his cheek as he held her.

"Liv, you're gonna be a great Mom, you are a great Mom. The only person who is to blame here is Cassidy. We left our son with his big Sisters, it's not like we just went out and left him alone."

"But if I had been there…"

"Then who knows what might have happened." He pulled away to look at her. "We are going to find our Son; the best detectives in New York are out there looking for him. And look who he has for a Mom and Dad."

"It's just the thought of him being out there somewhere… without us. What if Brian isn't feeding him or looking after him."

"Liv he took the bottles of milk from the fridge and his changing bag. So no matter how fucked up in the head he is, he was actually thinking about what he was doing. What we need to figure out is why and where he could have taken him. We are no good to Spud if we are sitting around blaming ourselves, we need to put our heads together and find him."

Olivia wiped her eyes and looked up at Elliot. She took hold of his face and pulled his head to hers and kissed him softly on the lips.

"Thank you," she said quietly.

"Anytime," he told her as she took hold of his hand.

"Now let's go and find our son."

"That's my girl," he said as they both headed to the elevator.

Xxxxxxxxxxxxxxxxxxxxxx

"Hey Sweetheart," said Elliot resting his hand on Olivia's leg as he crouched down beside her. "Liv," he said gently shaking her slightly. Olivia jumped up.

"What's happened?" she asked. "Do we have something?"

"No but your exhausted, we both are," he told her. They had been at the station chasing up leads for the last 15 hours.

"I'm fine," she told him looking round the busy office.

"Liv you need to rest, we haven't slept for almost 40 hours…Come on," he said taking her hand and pulling her up out of her chair.

"El, I can't…we need to find him," she said tears in her eyes.

"I know, but we need rest. Otherwise when we do get something we won't be in a fit state to help or be there for Spud."

Olivia looked at him and then around the room at everyone working.

"Just an hour… up in the cribs. Nick or Fin will come and get us as soon as they find anything out."

She nodded "Okay," she said quietly as Elliot led her up the stairs and into the cribs.

Elliot grabbed one of the beds and pulled it over next to another one.

"There is no way we can both fit onto one of those beds," he told her as he lay down. She smiled and lay on the other bed next to him. Elliot wrapped his arms around her and pulled her to him, her back to his chest. They both lay in silence for a while. Olivia pulled Elliot's hand up to her chest and held it tightly to her.

"El…What if they, we can't find him."

"Don't even think that Liv….. We can't think that or go down that road."

"But it's been almost 24 hours already that Brian took him, we have no leads."

"Liv, Brian took him saying he had come for his son. I really don't think he would have taken him to harm him."

"El, he hurt the girls….."

"Yeah because they were in the way of him taking Liam, I really don't think he will hurt him on purpose." As he said the words Elliot prayed he was right.

"I keep going over the last year with Brian trying to think of any places he has mentioned but I can't think of any. In fact the more I think about it I really don't know that much about him full stop. We never really talked….Not like we do. I don't really need you to talk to me, I can normally tell what you're thinking, before you even say it."

"You can huh."

"Yeah, and right now I can tell your just scared as I am. Your just as worried at what Brian might do, but you're doing what you always do and say what I need to hear. Your protecting me."

"That's my job Liv."

"And it's mine to look after you," she said turning around in his arms to face him when she felt his tears fall on her neck. "Partners for Life remember," she wiped the tears from his face.

"I just want our boy back," he cried.

"Me to baby," she said kissing him softly. Elliot kissed her back tasting both their tears as they comforted each other, and they both drifted off to sleep.

Xxxxxxxxxxxxxxxxxxxxx

Elliot opened his eyes but lay still on the bed not wanting to wake Olivia who was still asleep wrapped in his arms. He wasn't sure how long they had been up in the cribs. He carefully reached over to Olivia's bag and took out her phone to see what time it was. His heart began to race when he saw text messages and missed calls from an unknown number.

Hey Baby, you still working you should be done by now.

He opened the second message.

Liv getting worried now you're not answering.

Elliot looked down to check Olivia was still asleep. Before he began typing into the phone.

Sorry caught up in a case, will be leaving soon. Tried to call the home number but you didn't answer. How's the baby?

Elliot held his breath waiting for a reply.

He is good missing his mommy though, so hurry home.

"Liv…..Liv," he said shaking her.

"Hmmmmm….. Yeah," she said lifting her head and looking at him, she could something was wrong. "What's the matter?" she asked panic in her voice, as she sat up on the bed.

"This," he said handing her the phone. "I picked it up to check the time and saw the missed calls and messages."

Olivia took the phone from him and read the text messages. "You replied to him?"

Elliot nodded. "I couldn't exactly call him, come on," he said climbing off the bed. "We need to get a trace on the call when you ring him back."

They both hurried out the cribs and downstairs. Fin looked up from his computer when he saw them heading towards him "What's happened?"

"Cassidy has been trying to ring and has text Liv. We need to put a trace on the phone when she calls him." They showed everyone the messages he had sent.

"At least we know he is looking after Liam," said Nick.

"I don't care if that fucker has him wrapped in a gold blanket, he hurt my family and took my son," growled Elliot.

They got TARU into the squad room and set up the phone. Olivia looked at Elliot as she rang the number on the screen her hand shook as she held the phone, and it rang in her ear.

"Hey, Baby," said Brian answering the phone. "Where you been all day?"

"Sorry I got caught up at work on a case."

"Yeah I was worried about you."

"Yeah…I should, I should have called. I shouldn't be long though."

"That's good I missed you…"

"I…. I've missed you to. How's the baby?" She asked her voice breaking a little.

"He's good think he is missing his mommy though he won't stop crying. He could be just hungry." Olivia listened hoping to hear Liam in the background.

"I can't hear him is he asleep."

"No…. he's awake on the bed. Why do you sound so worried?"

"I'm not…I'm just missing him."

"Missing him Huh….like you were missing him last night?" he asked. "God you must think I'm so stupid, just like you all did all those years ago."

Olivia looked round at everyone "What do you mean?"

"What I mean is how much did you miss him last night Olivia, when you were out with Stabler!" he yelled down the phone. "When you were fucking Stabler in a hotel room, did you miss him then. I'm not stupid I know this kid aint mine I just said that so you would all think I had lost the plot. Christ how could he be mine when you wouldn't even sleep with me…. I was your boyfriend and you wouldn't let me even touch you. But you spread your legs so easy for that prick."

"Brian you need to calm down, it wasn't like that….."

"No Olivia it was exactly like that, what I want to know is how long were fucking Stabler behind my back?"

"Brian I ….. I wasn't….."

"So how the hell did you get knocked up?" Olivia heard Liam crying in the background.

"Brian, please is Liam okay?"

Cassidy started laughing.

"Cassidy I swear to god if you hurt him I will kill you," said Elliot into the phone.

"Oh look who it is, the mighty Elliot Stabler," he laughed. "Suppose you think it's quite funny do you, coming back into her life and taking her away from me, you always were jealous of the fact that I fucked her all those years ago. I was always the butt of everyone's jokes. Everyone always laughing at me, well nobody is laughing now," he told them, Liam was still crying in the background. "Everyone is taking me real serious now I have the kid."

"Brian what do you want from us, I mean what are you hoping for by taking him, he is only a baby," said Olivia.

"I want you to know what it's like to have your life ripped apart. You two tore my life apart, had me locked up in a mental hospital, I have lost everything….Jesus Christ will you shut the fuck up!" he yelled as Liam carried on crying.

"Brian we did it for your own good," said Olivia trying to reason with him. "You needed help."

"No what I needed was your love and your help, but you were too busy screwing Stabler."

Elliot moved away from the phone "Tell me you got a location on this prick," he said as they continued to trace the call.

"Almost there," he told him. "Just pin pointing the exact location."

"Just tell me where you are," said Olivia. "I will come over and we can talk about this."

"Nah, I'm done with talking. I'm done with you, done with the job, done with everything. We could have been so good together Olivia, I would have given you everything, and I loved you so much…. For fucks sake does this kid ever shut up…. Maybe I should put a gag on him as well," he laughed. "Get some peace and quiet."

Olivia looked at Fin when he said that. "He has someone else with him," he mouthed.

"What do you mean gag him as well?" asked Olivia.

"Oooops I said to much, well best go as I'm sure you're tracing this call….. Enjoy another child free night," he said before hanging up.

"Fuck!" cursed Olivia when the line went dead. "Please tell me you got his location."

The guy from TARU shook his head "We only got rough location, and there are hundreds of buildings in that area."

"Trust me, we will take anything right now," said Fin as they all looked at the screen and the location.

"Oh no," said Elliot looking at Olivia when they saw the area.

"You think he's….."

Everyone looked at them as they talked.

"He said gag him as well indicating he had someone else. If he has totally lost the plot and it sounds like he has then why not," said Elliot.

"But he never done anything to hurt him, why would he?"

"To hurt you Liv, Brian said it himself. He wants to take everything from you that you care about. He wants to hurt you."

"Excuse me," said Nick butting in. "But what the hell are you two going on about, do you know where he is."

"Yeah I think we do," said Elliot.

"We think he is at Cragen's new place, he bought a small beach house when he retired. It's in that area," said Olivia looking at the screen. "He has to be there."
