Hello readers! Welcome to Chapter 5 of Nightmare! It's a long chapter this time, yay! It also gets a bit darker as we delve into Rosalie's "Nightmare"

**This chapter includes a rape scene that may be triggering. It was hard to write because I didn't want to be too graphic and it went through many rewrites. Overall, I hope I was able to get the point across and I'll leave a warning before the scene.

Anyway, thanks Benson-Fan19 for your review! I appreciate it and I'm glad you are liking this story so far!

Chapter 5:

Rosalie woke up, her head pounding as if her brain was smashed with a hammer. What happened last night? She rubbed her eyes and as soon as she saw where she was, her heart plummeted into her stomach. She was in a dark windowless room with only a mattress against the wall, which she was sitting on, and a chain bolted to the floor which her ankle was chained to.

'Oh my God… ' Rosalie thought as she tried to get her ankle unchained, but it was locked and she didn't have a key or anything to unlock it with. She looked around the room, but no one else was there. Only her.

Now panicking, Rosalie scrambled around looking for her phone, but it was gone. Her dress was gone too. All Rosalie was dressed in was her bra and panties. This was reminding her of her mother's cases and it only freaked out Rosalie more.

Suddenly, a door opened and a man came through. He shut the door behind him and walked down a flight of stairs. Once he reached the bottom, Rosalie was able to see that it was the man from last night, Will.

"Good morning sunshine! I thought you'd never wake up," Will greeted in a cheerful manner. Rosalie wasn't comfortable with him anymore. She was now terrified.

"W-where am I? W-who are you?" Rosalie stuttered in fear, but Will only chuckled.

"I'm Will silly! You know me! I can't tell you where you are though," Will said in a joking tone which was unnerving to the scared girl in front of him.

"W-why? Why are you doing this? My mom's a cop and-" Rosalie tried to speak, but Will cut her off.

"I know your mother's a cop. She was the one who had me arrested and put in jail, but I got out and I'm out for revenge. I was going to go after your mother, but when I saw you…well let's say the plan changed,"

Rosalie went pale.

"Why me?" she whispered and Will laughed.

"Knowing your mother, kidnapping you would very well rock her world and she'd do whatever it takes to get you back, so for now, you and I can have some fun. I'll be back later beautiful,"

Will backed away and started to leave. Rosalie tried to crawl after him, but the chain kept her on the mattress.

"Please let me go!" Rosalie cried. "Please!"

All Will did was laugh as he went up the stairs, went through the door and slammed it shut, locking it.

Rosalie squeezed her eyes shut and prayed that when she opened them again, she would be at home and everything was just a horrible nightmare. When she opened her eyes though, she was still in that dark basement and she burst into tears. Why was this happening to her? She did nothing wrong! She tried looking again for a phone or some sort of way to escape, but she was trapped and she had no way of contacting anyone so she didn't know how anyone was going to know that she was missing. All she wanted at that moment was to see her Mom.

Olivia woke up the next morning feeling refreshed. It had been so long since she had a good night's sleep. She checked her phone and saw that it was past 10:00 in the morning. She had never slept that late before. She quickly got out of bed, took a shower and got ready for the day. Once she was good to go, she checked to see if Rosalie had come back while she was sleeping earlier. Rosalie's bedroom was empty and there were no texts or missed calls on Olivia's phone.

'She's probably having a fun time at Lolah's,' Olivia thought. She still sent a quick text asking when Rosalie was expected to come home. Rosalie always answered her texts right away, but this time, there was no answer. Olivia made herself some coffee and a quick breakfast of toast with jam. After she finished breakfast she checked again, but there still wasn't a response from Rosalie. Olivia was now a little concerned. She dialed Rosalie's number, but it went straight to voicemail. She waited a minute and tried again, but it still went to voicemail. Now Olivia was starting to get worried. She looked through her contacts and found Lolah's phone number and dialed it. After five rings, Lolah answered.

"Hello?" Lolah said groggily.

"Hi Lolah, this is Olivia. Rosalie's mom," Olivia greeted. "Is Rosalie still at your house?"

There's was a long pause before Lolah responded.

"I thought she went home late last night. We were hanging by Peter's Lake and we got separated. I assumed she left to go home…"

"Wait, why were you girls at Peter's Lake last night? I thought you two were having a sleepover?"

"Well we were going to, but we decided to check out this party by Peter's Lake and by the end of the night, I looked for Rose and she wasn't there. Is she not home?"

Olivia was now panicked. Something must have happened to Rosalie at the party! She quickly got off the phone with Lolah and began paging into work, asking for an AMBER alert on Rosalie, a sweep of Peter's Lake, and a tracking on Rosalie's cell phone. She hurried out and drove as fast as she could to the precinct. When she ran in, Nick and Amanda were at their desks. They looked up in surprise that Olivia was back early.

"Liv? What's wrong?" Amanda asked, noting that the detective looked frazzled.

"Rosalie went out last night and now she isn't answering her phone. I think she's missing. She never came home," Olivia explained quickly, hurrying to Cragen's office to let him know of what was going on. When she walked in, both Cragen and John Munch were there.

"Olivia? What are you doing back so early?" Cragen asked in a concerned tone. John noticed that Olivia was on the verge of freaking out and it worried him. Was something wrong with Rosalie?

"Captain, Rosalie went out last night to a party at Peter's Lake with her friend and she never came home. I tried texting and calling her, but she hasn't answered. Her friend doesn't know where she could be either,"

Both John and Cragen looked at each other with wide eyes. They instantly thought of the four murdered girls, but they didn't dare say anything to Olivia. Immediately Cragen said,

"John, get TARU on the line to track Rosalie's phone. I'll send Fin and Rollins to scout Peter's Lake with some officers and dogs. I'll call in the AMBER alert. Liv, we'll find Rosalie. I promise,"

John immediately got to his desk and rang up TARU, letting them know to track Rosalie's phone. When Cragen came out of his office and sent Fin and Amanda out to Peter's Lake, they were quick to head out. Even Nick quickly got to work in the search for Rosalie. This was Olivia's daughter and they weren't going to stop until she was found. Especially considering the recent murders. This could be that murderer on the loose.

Olivia hurried to her desk but was stopped by Nick and Cragen.

"Liv, you can't be on this case," Nick said slowly, knowing that Olivia was not going to like that.

"Nick no. This is my daughter, I am her mother. I am to be on this case!" Olivia demanded, her voice now shaking. Slowly the wall of strength she put up was crumbling. She was trying hard to stay collected, but inside, she was absolutely terrified.

"Liv, I'm sorry. We can take care of this. Go home. Maybe Rosalie will turn up and all will be fine," Cragen explained, but Olivia was having none of this.

"Nick you don't understand! What if this is the murderer of those four girls!? What if Rosalie is next?! I should have gone after her! I should have brought her home, but I let her go and now she's gone!" Olivia cried, the wall bursting. She started to hyperventilate, now fearing the worst had happened.

"Liv, breathe," Nick said, going over to her. Olivia tried to, but she couldn't stop panicking. John soon got off the phone and hurried over to the frantic woman.

"Liv, there's no signal on Rosalie's phone. TARU can't locate it," John explained.

"Crap…Nick take Liv home and stay with her. John, you and I will put out a high alert for this case," Cragen ordered. Nick nodded and while Olivia tried to fight, she ended up letting Nick take her home begrudgingly.

Once Olivia went inside her apartment, she checked if Rosalie came home at some point, but the apartment was empty. She sunk into the couch in the living room and held her head in her hands, trying hard not to start sobbing uncontrollably. Where could her daughter be?!

(TW: Rape)

It was hours before Rosalie saw Will again in the dark basement that was basically her prison cell. He came downstairs with another man behind him. Rosalie pressed herself against the wall, trying to be as small as possible. The men only laughed at her attempts of hiding from them.

"So this is Olivia Benson's daughter…" the new man remarked.

"Yup, in the flesh," Will answered with his wide grin.

"Please don't hurt me," Rosalie pleaded, but neither man acknowledged her pleading.

"God, she is spitting image of Olivia!" the new man exclaimed. "She had a better ass though, and she was much skinnier. Pudgy little thing this is,"

"Tell me about it. No one wanted anything to do with her when I found her at the party. Nobody likes fat little cows," Will sneered and Rosalie started to cry. Suddenly, she felt the sting of a hard slap from the new man.

"Shut up bitch! Nobody wants to hear you cry!"

Rosalie immediately bit her lip to stop from crying even more.

"Well despite all the blubber, I suppose we'll have to deal with it," the new man shrugged.

"Lowell, she's the closest thing to Olivia. Of course, we'll deal with it. We did with the other girls…"

Rosalie's eyes widened. She remembered hearing about a case that involved 4 missing and murdered girls which had her mother and the other SVU detectives busy trying to solve the case. These two men were the rapists and murderers! Rosalie froze as she realized that she was going to be the next girl in the headlines. She wanted to get away, but she was terrified to move. She was trapped like a fly in a spider's cobweb.

"Should we call dear Olivia and really torture her?" Lowell asked, but Will shook his head.

"Not right now. Right now, I'm going to have some fun," Will said, his eyes on Rosalie as he knelt down in front of her. Rosalie whimpered as she tried to back away, but there was nowhere to go.

"Aww, look at that. The baby's afraid," Will said in a voice reserved for young children. He reached out and stroked Rosalie's face. Each touch felt like fire on Rosalie's skin.

"Don't worry little girl. I'll take good care of you,"

His hand ran down her face and body before it reached her thighs. Rosalie trembled and went numb as he began to violate her. She did not want to remember what was happening to her. She didn't move, didn't speak, didn't cry. Silent tears trickled down her cheeks. She wanted all of this to be over.

Soon Will finished and stood up. He saw the frozen in fear Rosalie and chuckled. He turned to Lowell, who watched from behind, and said,

"She's all yours. I warmed her up for you,"

Lowell came over and sat on the mattress, hovering over Rosalie. She snapped out of her paralysis and began fighting, kicking and punching at the evil man.

"GET AWAY!" Rosalie screamed, but Lowell wasn't going to stand for a fighter. He punched her so hard in the face, that it knocked her out.

"Shit…I really wanted you to be awake for this. Oh well," Lowell said, annoyed. Still, he ripped off Rosalie's bra and panties and wasted no time before thrusting inside of her. The forced entry had Rosalie wake up and she screamed as she felt a ripping pain in between her legs. She screamed for Lowell to stop, but he kept going. At this very moment was when her childhood was taken from her.

This went on for what felt like hours to Rosalie. The men took turns violating and hurting her. They slashed at her body with knives. They burned cigarettes on her skin. They beat her with their fists and kicked her until she was black and blue. They forced her to drink alcohol and swallow pills to keep her quiet so they could continue torturing her. Eventually, they got tired of her and went upstairs, leaving her alone and bleeding. Her brain was foggy from the pills and alcohol, but the pain was agonizing. She wanted her mother before, but after everything that was done to her, all she wanted was to die.

John Munch made it his mission to find any sort of clue to would lead him and the other detectives to Rosalie. This mission was dangerous because if they waited too long, Rosalie could be next on the list of murdered girls. He wasn't going to stand by and wait for orders, he was going to keep searching until his Munchkin was found.

It was early evening, with the sun starting to set. John sat at his desk and thought about the evidence that was found from earlier in the day. When Fin and Amanda went to Peter's Lake, they didn't find Rosalie but they found her cell phone, which was smashed. It wasn't going to help them with this case. Interviews were conducted, but the witnesses they found never even noticed that Rosalie was at the party. Even Lolah when she was called in wasn't any help as a witness since she left Rosalie alone at the party and thought she went home. Slowly, everyone was losing hope in finding the girl that disappeared into thin air.

John didn't give up though. He thought and thought again, trying to piece together the puzzle pieces that were there. Who would go after Rosalie? A girl who kept to herself and never got into trouble. What if the perp wasn't going after Rosalie for herself, but was after her for Olivia? Could this be someone who wanted revenge on Olivia and decided the best way of doing so was to attack her daughter? He decided to check prison records and see if anyone was released lately. He searched through the records and recognized a name that popped up.

William Lewis.

He remembered that man. He was caught exposing his junk to some girls and later was caught attacking and torturing people. He was going to go after Olivia, but thankfully he was put in jail before he could do anything to her. He was released on good behavior, but what he saw next made his blood run cold. William Lewis was released from prison with his cellmate on the same day.

That cellmate was Lowell Harris. The prison guard who brutally attacked Olivia many years ago.

John couldn't believe it. Lowell Harris was supposed to be in prison for life. How in the hell did he get released?! He figured that it might have been overcrowding in the prisons and they needed room, but who knows. He immediately suspected that it could have been him and Lewis since both men wanted revenge on Olivia as soon as they were convicted. Maybe they conversed in their cell about a plan for revenge. He also thought about the other girls that were murdered. Were they attacked by Lewis and Harris as well? Right now, he needed to let Cragen know about this development. He hurried to Cragen's office and told him what he found. Immediately the two men were bumped to the top of their suspect list. Cragen ordered a swarm of officers as well as Fin and Amanda to the houses of Lewis and Harris. John asked if he could go as well since if Rosalie was in one of those houses, she'd probably want to see someone familiar. Cragen immediately agreed.

As John hurried back to his desk to grab his belongings, he suddenly stopped when he saw Olivia enter the squad-room. She was frantic, her hands shaking and her eyes red from crying.

"Olivia! You know you are not supposed to be here!" John exclaimed.

"I don't care John. I can't sit at home and wait for Rosalie to be found. I need to be here. I need to find my daughter!" Olivia cried.

"Liv…" John started, but Olivia noticed the other officers heading out of the precinct, wearing bulletproof vests and carrying their guns.

"What's going on?" she asked and John knew he couldn't lie about this.

"We think we found a lead. I checked prison records and…William Lewis and Lowell Harris were released recently…" John said slowly. Olivia's eyes widened and her face paled at the mention of those two men.

"Oh my God…Why in the hell was Harris released?! He was supposed to be in Rikers for life!" Olivia gasped.

"I know. Overcrowding in Rikers and Lewis was released on good behavior,"

"Do you think they…." Olivia trailed off. Flashbacks of her assault flooded her mind. She remembered when he received his prison sentence, how he had to be dragged out of the courtroom because he was screaming that he was going to kill her and that this wasn't over. She remembered holding Rosalie extra tight that night, terrified that Harris would come and find her and hurt either her or Rosalie. She automatically knew that Harris had something to do with her daughter's kidnapping. It was a mother's instinct. She just knew.

"Liv, Cragen ordered Amanda, Fin, and some other officers to search both of their houses. I'm going as well. If we find Rosalie, we will let you know,"

"No, I'm going with you," Liv said defiantly as she went to her desk and pulled out her bulletproof vest.

"Liv no! You can't be on this case!"

"I DON'T CARE!" Olivia yelled. "My daughter's life is at stake! I need to find my baby!"

She felt tears spring into her eyes as she slammed her hands on her desk.

"I've fucked everything up John. This is all my fault. When Nick called me last night, Rosalie thought I was going back to work so she snuck out to Lolah's and I thought nothing of it. If I went after her, she would have never gone to that party and none of this would be happening. I let work take the front seat and now she thinks I'll never be there for her. I can't lose her John. I need to be better for her. I…" Olivia's voice cracked as her tears became sobs. John immediately went over and pulled her into a hug.

"Liv…you can't blame yourself. You are a good mother. I know how much you love Rosalie. You work hard to protect her from the harm that is out there,"

"But not this time!" Olivia sobbed, burying her face in John's chest.

"We will find her Liv. I promise you, we will find her. You have to trust us. We're all going out and we will call you when we find her. The last thing I want to see is you getting in trouble with Cragen," John reassured her. Olivia pulled away and shook her head.

"I'm coming with you, John. You can't stop me,"

John sighed. If there is one thing about Olivia, she wasn't going down without a fight. When her mind was made up, there was no changing it.

"Fine, but when you get suspended, don't come crying to me," John finally said as he grabbed his gun and vest. Olivia sighed in relief and grabbed her stuff. The two hurried to John's car and got in. As they drove, they heard from Amanda and Fin that there was nothing at William Lewis' apartment and that they were heading to Lowell Harris' apartment next. John replied that he and Olivia would meet them there. Neither Fin nor Amanda said anything about Olivia joining them. They knew she wasn't going to sit back for long.

When John and Olivia arrived at Harris' apartment, there were cops already there. They hurried out of the car and watched as some officers broke down the door and entered the space. Olivia and John pulled out their guns and joined the officers inside. They searched every room, but Harris wasn't there and neither was Rosalie.

"All clear!" an officer called.

"Damn it!" Olivia snapped as she slipped her gun back into its holster. She looked around the living room, which was the room she was standing in. The place was dark and dirty, but there wasn't anything around that could be a clue. She looked down at the floorboards and noticed one that seemed loose. She got down to the floor and pried it loose. Lifting up the board, she saw what looked like a treasure trove of pictures.

"I found something!" Olivia called as she slipped on some gloves and pulled out the pictures from the floor. What she saw made her blood run cold.

There were HUNDREDS of pictures of Rosalie. Rosalie leaving school. Rosalie walking home. Rosalie hanging out with Lolah. Harris and Lewis must have been stalking Rosalie for awhile. What was also found was a collection of photos of the other girls that were murdered. Eloisa Beckett, Georgie Lively, Allison Winters, and Hannah Strong. There was now an answer as to who murdered these girls. Yet Olivia couldn't feel relieved with Rosalie still being held captive by these bastards. She handed the pictures to another officer who bagged them as evidence and she stood up with the intention of searching for more evidence, but suddenly Cragen and Nick burst into the apartment and beelined towards Olivia.

"Detective Benson, I made it very clear that you were not to be on this case. You completely disobeyed me," Cragen said sternly, before turning to John. "Sergeant Munch you know better so don't think you're off the hook,"

"Captain, I told him that I was going to go with him. It wasn't his choice. I wasn't going to sit back and wait. I want to find my daughter," Olivia explained, trying to put the blame on herself. She knew she was in the wrong and didn't want John to get in trouble.

"Detective, I understand but this is a family case. You can't be on it. I'm sorry," Cragen said. "If this happens again, I will have to suspend you,"

"I understand…but we did find pictures under the floor. They are of Rosalie and the four girls. We know that Harris and Lewis were the ones who killed those girls and has Rosalie," Olivia explained. Cragen nodded before saying,

"Alright. Munch, stay here and continue to look for evidence. Benson, you are coming back with me and Amaro and you will be staying in my office until we solve this case, do you understand?"

"Yes sir," Olivia sighed as she walked out of the apartment with the Cragen and Amaro behind her. Once she was gone, John immediately got back to searching for any more evidence that could tell him the location of Rosalie. He went through drawers and was looking for more loose floorboards when he heard,

"I found something!"

He ran into the bedroom where Amanda and Fin were located. Amanda had gone through Harris' desk and found a notebook. On the first page was a list of supplies.

"Chains, knife, blowtorch…" Amanda read and John felt like he was going to be sick. Were these sickos using these items to hurt Rosalie? He prayed that wasn't the case.

The rest of the pages were blank, but on the very last page was an address. An address of a house upstate.

"That must be where they are!" John exclaimed. Amanda sent a text to Cragen and they were given the go-ahead to search the location. As John jumped in his car and began driving with the other officers, he prayed that Rosalie was at that address from the notebook and that she was uninjured.

A/N: That was...a lot to say the least. If you made it to the end, thanks for sticking with me. Will Rosalie be rescued? Stay tuned for Chapter 6! ;)
