A few days have passed since the attack. A few days have quickly flown by since Erin has seen or even heard from Tucker. She wanted to feel relief, but the thought of him still being out there, terrified her. He could be planning something. He could be watching and taking pictures of her. Over the few days that have passed, Erin was constricted to school, Jay's apartment or the precinct. An officer had to be with or near her 24/7…her father's orders not hers. She didn't mind it when she was alone, but when she was in a public place, she felt no fear. Tucker wouldn't strike in a populated area. He couldn't be that stupid. Voight didn't want to take the chance though. Tucker was grower bolder with each passing day. He didn't trust the guy. He didn't know what he was planning next. Voight wanted to stay one step ahead, leading him and Jay to bring Erin to the county courthouse.

After hours trickled on by, Lindsay follows her dad and boyfriend out of the courthouse. In her hands is a file, and inside that file is a restraining order. The three individuals carefully walked down the outside stairs, "Okay, dad I want to run something pass you."

Hank hesitantly eyes her, "What is it?"

"Some classmates at school are having an early Halloween party."

"Halloween isn't until next week."

"That's why it's an early Halloween party," she reminded, feeling the wind blow her coat open, "I wanted to go." She hands Jay the folder so she can hastily button up her coat.

"Are you asking me or telling me?" Hank stops walking and turns to face his daughter.

"…a little bit of both."

He's hesitant, "I'm not sure."

"Dad, I've been cooped up in Jay's apartment and the precinct since last Thursday." She pulls her father to a stop, her hand on his shoulder as her eyes pleaded with the stubborn man, "It's been six days. I need to get out."

"Tucker is still out there."

"I know," her hand dropped, giving him a hopeful look, "which is why I wouldn't mind if you had an officer or two follow me."

"Two officers parked outside a loud and crowded costume party isn't safe. They can't keep their eyes on you…and everyone's dressed up. Tucker could easily blend in and hide himself."

Lindsay knew her father made a good point. She didn't want to be stupid about this. She really wanted to go, but not at the expense of her safety. Erin was missing out on the remainder of her college years. It had only been a few days since his attack, but she felt stronger. She was no longer in denial. If he tried anything, she would tell her father immediately. He hasn't done anything for her to tell him…maybe, possibly, he was done. Lindsay thought about the party. The classmates who invited her, she met her first year of law school. A week before midterms and finals, they would form a study group and review their coursework together. They had heard about what happened to her –most people at the university did- and to cheer her up, they invited her out. Erin needed to go.

"What if they come inside?" The thought occurs immediately. It's her last attempt to convince her dad. If he said no, she wouldn't go.

Voight chuckled at the idea, "You want two cops at a college party?"

"Well, no one has to know they're cops." The idea sounded absolutely perfect in her head. It was a win-win on both sides. She gets to go out and have fun while her dad remains sure that she's safe. Erin grabs his hand and yanks it desperately, "It's a Halloween party. Everyone will just assume they're in costume."

"What do you think?" Hank looks to Jay. He trusts him enough to know he'll always put Erin's safety first.

Jay's eyebrows furrow in worry, "I'm not sure-"

"Tucker hasn't shown up. He hasn't contacted me at all."

"That's because we haven't left you alone…" Jay reminds, turning his girlfriend to face him.

She's a debater. She won't give up easily. It's not who she is. It's not how she was raised to be. "And I won't be alone…I'll be surrounded by tons of people."

"Tons of drunken people who won't be watching your back," Voight chimes back in. It's two against one now. Erin still doesn't back down.

"That's why your two officers will be there."

Voight rubs his forehead, "I don't trust everyone with you."

"Well, assign me cops you do trust." Erin feels like she's stating the obvious. She understood her father's worry. She was worried too, but she couldn't put her entire life on pause because of this guy. He would be winning. Erin couldn't let that happen, "Give me Burgess and Roman."

"We'll see," Voight begins walking in the direction of the parking lot, "I'll get the car."

She shouts behind him, "That isn't a no!"

"It's not a yes either!" He hollers back.

Erin and Jay stood in front of the courthouse, waiting for her father to bring the car around when she opens up the manila folder, "I still don't see the purpose of this," Erin reads Tucker's legal name printed across the restraining order declaring that he must stay a certain amount of yards away from her, "This won't keep Tucker away."

"We know," Jay rubs his hands together, trying to create warmth for his cold palms, "We're building a case against him. The more stuff we have to charge him with, the longer he'll be put away. If he violates that and comes anywhere near you, it'll just add time to his sentence."

Erin closes the folder, "That's actually smart."

Lindsay places the file under her arm. Her pea coat was buttoned up, and she stuffed her hands into her pockets. It's mid-October and it is absolutely freezing outside. Jay is rocking back and forth, contemplating ways to bring up a certain subject with his girlfriend, "You've been staying with me for the last six days, and I've really been enjoying your company."

She smirks, "What are you hinting towards?" She wants him to get straight to the point.

"We should make this living situation permanent."

It was a step up in their relationship. The couple is young, they've been dating for seven years and moving in together was the next appropriate step to developing their relationship.

The days that followed Erin's attack was filled with overtime pay for officers and a lack of sleep for the detectives. Roman and Atwater managed to issue an arrest warrant for Tucker. He's currently being charged with breaking and entering, assault and battery, harassment and stalking, and attempted murder. Erin felt comforted knowing that if he's found guilty for each crime, he'll most likely serve at least 15 years. She felt Jay's arm wrap around her shoulders and pull her in close, "You don't have to give me an answer now."

The following day after the arrest warrant was issued, Dawson and Ruzek managed to get a warrant for the security footage at the apartment complex. They needed all of the evidence they could get. It's one thing to charge Tucker with these crimes; it's another thing if they can't prove it. Unfortunately, only one camera was working. The other cameras had been broken since way before Erin even met Tucker. Her dad was the very definition of pissed. When Erin first moved in, the landlord prided the complex on the safety of the apartment and the neighborhood. Fortunately, the camera that did work was to the main entrance. They saw Tucker as he entered the apartment wearing a clown costume and holding up a large box, to which they all new was filled with snakes. Most of the evidence they had against him was circumstantial and with a good lawyer Tucker could definitely get off…but Erin wasn't worried about that. She knew her father. He would do everything in his power to not allow that to happen.

"Erin," Jay nudges as her father pulls up.

Voight is honking at them, "Come on! We have to get to the precinct. Mouse called." The couple is quickly hopping into the car, trying to avoid the honks of protest from the automobiles stuck behind Voight's truck, "He may have found Tucker's location. The team is meeting us there...at the precinct."

"Where am I going?" Erin buckles her seat belt. She doesn't have classes. She was absolutely free of plans.

"…with us," Jay states the obvious. Just because they knew Tucker's location, didn't mean Erin didn't need protection. Until he was in police custody, she would remain under an officer's watch. Jay buckles his seat belt as Voight speeds off, "When we find out his location, you'll stay upstairs in the bullpen. We'll send an officer to my apartment to get whatever you need to entertain yourself. It's just until we have him."

Erin understood their worry. They had reason to be concerned, it was just…it felt weird having everyone babysitting and protecting her. The Intelligence Unit had cases that still needed to be solved, but they were focusing on her. There were victims out there waiting for justice. Families and friends of victims were waiting for closure. She didn't want everything about her. The only reason her case is even getting this much attention is because her father's the sergeant of Intelligence. If she was a regular citizen with no connection to law enforcement, they would probably brush her case under the rug, file it away and tell her to keep a log of everything that Tucker does. She'll be doing most of the work, but because her dad is Hank Voight, none of that happened. She wasn't grouped with everyone else.

The Chicago traffic was bad today. Over the span of six days, this was the biggest lead they had, and Voight was desperate to receive the location and arrest him before he disappeared again. Tucker hadn't been at school. He still had an Indiana license, and the address listed was in Indiana. They didn't know where he resided in Chicago. All school files and documents registered his Indiana address. Voight was growing frustrated. He was tired of honking his horn and merging in and out of lanes. Without a second thought, he turned the sirens on.

"This is cool," Erin whispered, as the car sped up to an unreasonable speed limit, "Why have I never rode with you when the sirens are on?"

"…because the driving gets dangerous," Voight responded, eyes focused on the road. Cars pulled to the side of the road in order to allow his truck to pass.

"We have to do this more often," Erin felt a rush of adrenaline. As an abider of traffic signs and the speed limit, she has never gone so fast. Her car barely went ten over the speed limit. It felt like her father was pushing twenty or thirty over.

"…not a chance in hell," Voight responds, making a sharp right turn.

She shrugs, "It was worth a shot."

The precinct is straight up ahead. The sirens are cut off. A crowd of officers is formed in front of the district. They're surrounding something or someone. Voight does a rush parallel parking job, but his car is out of the lane, so he immediately deems it acceptable. The three jump out of the car. Jay sticking close to Erin, as Voight pushes through the uniformed officers and the plain-clothes detectives, "What's going on?" Hank spots Dawson.

Before his question is answered, he notices the reason for the small crowd of officers. In the center of them is Tucker, he's on his knees and his hands are high in the air. Olinsky is pulling Tucker's arms behind his back as his rights are stated loudly for everyone to hear.

"I heard there was a warrant out for my arrest," Tucker admitted, his voice shaken and innocent, "I came to turn myself in. There must have been some misunderstanding." Olinsky roughly pulls him to his feet, "Hi Erin," he spots her standing beside Jay. Erin doesn't respond. She bites down on her lip as images of that night flashback in her mind.

"Where are you taking him?" Hank questions Olinsky, but his eyes remain on Tucker.

"…to booking."

Hank shakes his head, "I'll take him." No one protests.

Officers begin to head to their assigned cruisers or back into the district. The Intelligence Unit remained outside. Voight's arm is wrapped tightly around Tucker's handcuffed arm, while Al's remain secured around the opposite arm, "Voight."

"Al, let him go."

"Where are you taking him?" Olinsky sounded nervous to ask the question.

"I'm not going to kill him if that's what you're worried about."

Tucker is quiet. His eyes are on Lindsay. There's nothing he can do to pull his eyes away from her. It's like an addiction. He has to watch her. He has to have her. She was his prize and he was going to win her no matter what he had to do. He ignored Voight and Olinsky's arguing as his eyes remained focused on her. He's looking hard. He's observing every minor body movement she makes. She's biting her lip. She's avoiding eye contact by looking down at the ground. She's tapping her fingers against her jeans. His presence made her nervous. If they were alone, it would make her submissive. Tucker grinned widely. Seconds later, Jay notices, and steps in front of Erin, obscuring his vision of her. Tucker's grin falls.

"Let him go! That is a direct order Olinsky."

Al is hesitant, "I'm trying to look out for you Voight. You're too connected to this. If you do something…anything, it could ruin our chances of a conviction. You're too close to the case."

"If I'm too close, then we're all too close," Hank pulls Tucker away from Olinsky, "Walk, now."

As Tucker follows Voight's order, he gets a quick sight of Erin. He smiles at her, and she feels forced to turn away. Tucker chuckles silently to himself. This is all going to be fun. The chase is always the exciting part. The team follows behind Voight and Tucker as the sergeant leads him into the cage. Tucker feels forced inside, "What is this?" The handcuffs are unlocked from around his wrists, "Is this a cage? This can't be legal. I'm in a cage."

"It's usually where we keep the animals," Ruzek quipped, locking the cage.

Voight holds his hand out, "Keys Ruzek…now." He follows Voight's orders and hands him the keys. Hank steps to the cage and wraps his fingers around the cage bars, "I need some alone time. Give me a few minutes."

Olinsky scratches his beard, "I don't think-"

"That's an order!" Voight hollers, turning to face his closest and oldest friend. They're face to face, a few feet apart, and the look on Voight's face is intimidating…he's waiting for Olinsky to violate the order. No one…no matter how close he is to them is going to stop him.

Hank notices the quick flinch of his daughter when his voice rises. She has seen him angry, but not this angry. His face was red. His eyes were wide. A stress vein was visible on his forehead and she was afraid that if he strained his face harder, it would pop. Voight's face relaxes at the sight of her. He doesn't want her to see him like this. He wants to keep his work and family life separate. Hank takes a deep breath and steps back, "Halstead, take Erin to my office. Wait for me there," Jay nods and does as he's instructed. Erin doesn't argue. She follows her boyfriend out of the room. Hank turns back to his team, "I'm not going to kill him. I just want to talk to him…alone. I have that right as sergeant of this unit and as her father," he points off into the direction Erin disappeared in, "If anyone has a problem with that, I suggest you transfer out of my unit. Am I understood?" Everyone nods, including Olinsky, "Now get out of here."

Jay ushered Erin into her father's office and closed the door, sighing in relief at the sight of the empty room. Erin was still holding onto herself as tightly as her strength would allow and he eased himself towards her, pulling her body into his arms, "We got him."

Erin pulls free. She starts pacing. Her head is shaking and her arms are clenched even tighter around her body, "Tucker must have something up his sleeve," her arms drop from around her body and she begins stressfully rubbing her forehead, "He's not stupid Jay. He's manipulative. He thinks things through. He may be impulsive at the moment, but afterwards he knows how to lie and cover his trail."

"He's in our custody now," his hands are set on her shoulders, preventing her from continuing her pace, "He's not going anywhere. He won't hurt you again."

"He's smart Jay."

"He's not smarter than Hank Voight."

She swats his hand away, "You're underestimating him."

"Your dad will handle it."

"How?" Erin steps back. Her hands are thrown in the air, "How Jay? My dad is acting on pure emotion. Tucker is acting on pure calculation. He's going to get out of here."

"No he won't."

"I am the end goal. He won't give up until he gets it."

"He won't get a chance." His voice is pleading for her to believe him.

"…of course he won't," she's nodding her head, "because he has never gotten the chance before, right? He never risked it all to be with me, right Jay?"

Halstead ignored the sarcasm, fully aware that Erin was trying to deflect from the situation and the conversation. He could tell she was shaken up and worried, and Halstead didn't blame her at all, but making light of the entire situation wasn't going to change the fact that Tucker had targeted and attacked her.

"You have to stay strong babe. You can't let him get to you. Don't let him see that he's getting to you Erin. He'll pry upon that."

Her voice tries to sound strong, but it fails, "He's going to come for me."

"No he won't."

Erin is quiet. She drops her arms and sets her hands on her hips. She could see through the window in her father's office, the team trying to look busy. They were listening. She didn't care. She knew she was right. Tucker will find a way. He's desperate and he's thinking clearer than her father. Erin was just pissed to find the rest of the unit –more specifically- everyone but Olinsky, were blindly following him.

"Say something."

"Sometimes," she bites down onto her bottom lip, it's her nervous habit, "saying nothing Jay, says everything."

"We have it all under control."

Her hands drop from her hips, "…of course you do."

"Erin-"

"No Jay," she's shaking her head as she begins pacing again, "You guys are detectives. You're trained for this type of stuff, right? You're trained to pick up on lies. You see through people. You question them. You can see things coming from a mile away, am I correct? You can look at someone and know they're bad news. You can predict what's coming. You can read people. You can predict what they're going to do next. Am I right? I know I have to be right," she stops and looks up at the ceiling furiously before dropping her eyes back to him, "You all have this precognition that gives you the ability to see the future. That's the only way you can assure me that this won't blow up in my face…because I'm the only one that's going to pay here! Tucker doesn't want you Jay. He doesn't want my dad. He couldn't care less about Burgess, Roman, Ruzek, Atwater, Dawson…he wants nothing to do with them! So tell me," her voice finally lowers as she steps to him, "look me in my eyes and tell me that you can see the future and that's how you know it's all under control." Her eyes are full of tears that refuse to fall, "You can't. No one is psychic here. If you can tell me how this will all play out, then I'll shut up, but you can't. Every day we hear about innocent people going to prison while guilty people walk free. The scales of justice are out of whack. Tucker is going to walk…if you can't see that, then I'm not the only one who is in denial."

The young detective saw the pain in his girlfriend's eyes. She was scared. She was speaking out of emotion. Erin was trembling. Every day they would tell her to think about something else, clear her mind, but when she's forced to only go to three places a day, she doesn't have the freedom to think about other things. That was the main reason she wanted to go to this party. It would give her brain a few hours to think about something else besides Tucker.

"We're not psychic-"

"Of course you aren't," her voice breaks in desperation, "if you were, none of this would be happening. I wouldn't have been attacked. Tucker wouldn't have had the chance to do everything he did. I would be fine." She's shaking her head, "but you're not psychic. You can't predict what will happen down the road…so stop standing here and telling me what you think I want to hear. I want to hear the truth. If I wanted to be lied to, I would talk to anybody else. You don't lie to me Jay…so you don't have to start now." Lindsay stepped forward, lacing her fingers through his. Her forehead rested against the center of his chest, "You don't have to be strong for me. I can take it. Whatever you're feeling, I can take it."

"How can I help you? Help me, help you."

She can tell he's avoiding his emotions. He's covering what he's feeling with a mask that she'll eventually pull off. She's the one affected the most, but by Tucker hurting her, it affected those she cared about. Erin decides not to pry. When she would push him away, he never pried and she'll do the same for him. With her head resting against his chest, she responds, "I would really like to go to that Halloween party. Tucker's here…it's this Saturday…two days from today."

"I'll try to convince your father," there's a soft knock on the door before Dawson speaks up.

"Erin, we want to ask you a few questions."

Jay lowered his hand, opening and then guiding Erin through the doors and out of her father's office. Contact between the two never breaking as she takes a seat in front of the unit.

Tucker felt someone grab the back of his shirt and toss him as far as five feet from where he was standing. The air left his lungs as he slammed into the ground. Someone towered over him, brown eyes dark with hatred. Voight reached for his shirt, and crashed his back against the cage, "Did you really think you were going to get away with this?"

Tucker's lip is bleeding, "There's no proof for what you're accusing me of." His feet leave the ground briefly as Voight tosses him back into the cage, "it's Erin's word against mine." Tucker rises from the ground and wipes his lip with the back of his hand, "I'm innocent. Any judge and jury will see that. What do you think the public will think knowing the sergeant of the year is threatening an innocent law student?" There's a bench in the cage that Tucker takes a seat upon, "They'll think you're bias. The supposed victim is your daughter. Of course you'll believe everything that pretty little mouth of hers says."

"You stalked her."

Voight has to close and lock the cage door. If he keeps it open any longer, he'll kill him. The likelihood of him ripping Tucker's heart out of his chest was high. Olinsky should have stayed down here with him. Voight shoves the keys into his pocket as Tucker remarks, "I didn't stalk her. I didn't do that. I wouldn't do that. Stalkers are creepy. They can't take no for an answer."

"You just happened to show up everywhere she did."

Tucker is arrogant, "I'm pretty sure, and you can run it by Erin to make sure, but I'm pretty sure that any place we showed up to by chance was public places. I know there's the library, the park, the café, the mall…I can't really think of the rest right now."

"You took pictures of her Tucker. We have them."

"How do you know I took those pictures?" Tucker leans his back against the wall, "Anyone could have taken them."

"You left her presents."

Tucker sits up, "You have those? And I'm pretty sure leaving someone gifts isn't a crime."

The sergeant's hands grip the cage. He has the keys in his pocket and he's trying everything in his power to keep them there. Voight moved his face closer to the cage, "You broke into her apartment Tucker."

"What proof do you have?"

"Erin told me."

"Her word against mine," Tucker reminded, drumming his fingers along his pants, "Of course you'll believe her though…she's your daughter."

Voight reminds, "You left your shoes there."

"Before Erin and I had our falling out, I had visited her…multiple times. We hung out a lot. I must have just forgotten them there."

Voight's fingers grip the cage even tighter, "That's bullshit and you know it."

"So," Tucker intertwines his fingers over his lap, "is that it?"

"You dosed her food with walnut sauce. You tried to kill her!"

"I would never try to kill her!" Tucker shouts, rising to his feet, "I would never do that! I would never try to hurt her! I wouldn't! I love her too much to kill her!"

"What do you think dosing her food with something she's allergic to would do Tucker? You can't be that dumb. You can't be that much of an idiot."

Tucker is inhaling sharp breaths, "I didn't do that. She should be thanking me. You should be thanking me. Both of you should be happy that I was there to save her."

Tucker truly believed every word his mouth was spewing. He looked into her father's eyes. They resembled hers. He pictured Erin. He could see her in her father's eyes. He softly smiled, "Is there anything else?" He was ready to be with her. Tucker was growing impatient.

"You dressed up as a clown, broke in and put snakes all over her apartment. You hit her." Voight pulls against the cage, but Tucker doesn't flinch, the cage door is still locked, "You terrorized her! You did that to her Tucker! You scared her! You hurt her! You did the one thing you vowed to never do! How could you do that?" He wanted to play on Tucker's emotions.

However, he wasn't falling for it. He's smug, "Once again sergeant, how do you know this? How did such an inept sergeant win the sergeant of the year award? The competition must not have been hard this year. Isn't there some rule in place to prevent you from investigating a case so close to home? You have questioned me without my lawyer present. You have thrown me around. None of this is legal."

Voight pulls the keys from his pocket, a straight, yet intimidating look on his face the entire time, "You want to know what else isn't legal?"

"What?"

"The ass whooping I'm going to give you if you don't wipe that sick smug look off your face."

"Sergeant Voight," an unrecognizable voice interrupts, as a high heeled lady walks over to him.

He ignores her, "If you do get out of here, you better not even think about touching her. If you do Tucker, you'll have to deal with me…and I don't think you want that."

Hank steps into the cell, pulls his handcuffs out and hooks them around Tucker's wrists. The law student is smiling at the sight of his lawyer. She heard the threat. Tucker is gleaming proudly. He had called her before going to turn himself in. He'll be out soon. He knows the process. This isn't his first rodeo with the police. It's the reason he's in law school. He wants to be able to beat them at their own game. If his lawyer knew how to do her job, he would be out by tomorrow.

"He questioned me without you present," Tucker informed his lawyer as he was escorted out of the cage, "He wouldn't stop questioning me."

"I hope you know that anything my client has said is inadmissible in court." The lawyer followed Tucker and Hank as they walk to booking.

Voight pushes him up the stairs, "Since you're here now, I can ask all the questions I want. Isn't that right?" He side-eyes Tucker.

"Now you're acting like you know the law," the smug smile is still on his face, "It seems that-"

"Who's Valerie?" Hank's question silences Tucker. The young man has nothing else to say. He eyes his lawyer and shuts his mouth. The smugness in his expression is long gone.

Voight spots an officer. He managed to get Tucker silent and he's satisfied with that. Hank waves the rookie cop over, "Book him." The officer nods, "and make sure you do it right," the rookie cop takes Tucker and leads him and the lawyer away.

"Mr. Voight," Tucker calls innocently, briefly looking over his shoulder, "tell Erin I said hi."

It takes every fiber of Hank's being to not run over to him and beat him to a pulp. He hated the smugness of Tucker. He walked with confidence. He walked as if he knew everything he did wouldn't stick. Voight buzzed himself up and took two stairs at a time, "We need to find something…we need anything to keep Tucker here."

"Boss-"

"Where's Erin?" Hank scanned the room.

Burgess answered, pointing towards the breakroom "…in there getting coffee."

"Boss-" Mouse turned his computer to face Hank.

He ignored Mouse's calls, "Erin…Erin come out here." Voight tries to replace the worry in his voice with confidence. He didn't need her worrying about anything.

"Boss-"

"What is it Mouse?!"

"I found something," he announces, earning head raises from everyone in Intelligence, "I found Valerie. It took a lot of digging, but I-"

"Get to the point. Where is she? Is she alive? Is she dead? What happened to her?"

Erin's coffee is long forgotten. It's sitting on Jay's desk as she approaches Mouse, "What happened to her?"

"She's in Indiana." Mouse answers, eyeing the team.

Jay sighs in relief, "So, she's okay?"

"No," Mouse shakes his head and pulls up the online article from the small town in Indiana, "She's in a coma. She's been in one for the last year." The computer tech turns his computer back to face him, "Doctors don't think she's going to wake up. She's showing very little brain activity. Her family refuses to pull the plug."

"Does it," Burgess is nervous to ask, "Does it say how she ended up in a coma?"

Mouse skims the article, "It says…she fell off a six-story building."

"I bet she was pushed," Erin crosses her arms and looks up when the team acknowledges her comment with the rise of a brow.
