Chapter 15

21st district

Hank slammed his hands on the table in anger. "You're trying to tell me you haven't been following her around for more than a month ? That these aren't your photos ??" he threw the pictures they had collected from the walls of the house at him. "Do you think I'm stupid??"

Ken smirked at him. "Do you really want me to answer that?" he responded , causing Hanks face to twist in anger.

"Listen, we know you killed those two girls." Jay was the more calm of the two men, but he did that on purpose. "You might as well confess to everything then we can talk."

Ken laughed. " You have no clue. I wanna talk to Kat, she's the ONLY one I'll talk to. If she isn't here, then I want a lawyer. "

The dreaded L word. "There is no way in hell I'm letting you NEAR her." Hank growled at him and threw open the door to the interrogation room, storming out.

Jay just shook his head. "That isn't going to happen, so you might as well forget it. You tortured her, you really think she wants anything to do with you?"

Ken shrugged. "Did I?" he sat back, arms laying in front of him on the table. "LAWYER. You know that word right?"

Jay could see he wasn't going to get anywhere so he picked up the file and walked out, striding to the bull pen. "Did he crack?" Adam asked , and got his answer when Hank slammed his door open , striding towards the group .

"Lock him in a cell. We have his DNA on the two girls at least, we can book and charge him for those murders. I don't want him anywhere near Katie, you got me?" he didn't wait for an answer from anyone, he just walked out.

The team looked confused , except for Jay who knew exactly what he was referring to. "He said he would only talk to Kat…" Jay trailed off, and the rest of the team shook their heads.

"No wonder Voight is livid. " Kim spoke up. "But if there's a way it can help…"

Jay shot her a look. "Not only would Voight not go for that, neither would Antonio. There is no way. We just need to get the proof he's responsible for everything . Leave Kat out of it."

They sat down and started the paperwork to book Ken for murder of the two minors. Jay sent a text to Antonio so he would be caught up whenever he made it back to the district.

Antonio heard his phone vibrate, pulling him out of the peaceful thoughts he was having. He looked over and saw Kat still curled up next to him, but her brow was furrowed, like she was having a bad dream. He kissed the wrinkles in her forehead and that seemed to help ease whatever she was thinking about. A smile replaced the upset look and she sighed. Antonio eased out of the bed and grabbed a pair of boxers and sweatpants from his dresser before heading to the kitchen. He checked his phone and found a text from Jay.

Tonio- Ken will only talk to Kat. Voight is NOT on board. Keep an eye out bro.

Antonio responded – thanks for the heads up.

He grabbed a beer from the fridge , popped the top and took a long pull. This guy was nuts if he thought Kat would ever be in the same room as him, let alone TALK to him. He stood there a good 10 minutes when he felt Kats arms wrap around his waist and turned around. "What are you doing up? You should be asleep." She had grabbed one of his shirts and was wearing it and nothing else.

"I got lonely." She smiled shyly at him. He leaned in to kiss her when he heard a familiar pounding at his front door.

"That'll be Voight. You might want to…" He pointed towards the bedroom. She nodded and scampered off, before Antonio opened the door. "Hank."

The older man nodded and came inside. "This bastard wants to talk to Katie. Can you believe the nerve?" Hanks face red in anger. "He is looking at life, and he wants to talk to her."

Kat had gone and changed into sweatpants , and was standing in the hallway listening. She tried to think of why Ken would want to talk to her, and decided if it helped them put him away, she would do it. "Dad?" Both men turned towards her when they heard her speak. "If it will help you in any way, I'll do it."

Hank moved across the room in no time. "No way in hell is that man ever going to be in the same room as you ever again Katie. I don't care what his angle is, it isn't happening. " He pulled her close and kissed her forehead. "Now" he changed gears "How long did you two think you could keep this a secret from me?" he gave Antonio a look that made him shift his gaze to the floor.

"Keep what Sarge?"

Hank gave him a death glare. "I waited to see if you would tell me on your own, but I see that isn't happening . "

Kat pulled away and walked to Antonio, tucking herself under his arm. "Its new." They glanced at each other . "We weren't being misleading on purpose it's just… "

"Sarge I love her." Antonio spit out. "I'm sorry I wasn't honest with you when it first happened, but I'm being honest now." His hand curled around her hip possessively. "I want her to stay with me. If that's okay with her." He added , grinning down at Kat.

The look on her face told Hank everything he needed to know, and erased any fear he had of the two of them being together. She was over the moon for this man, a man that Hank knew to be a really good guy. He was fiercely loyal , loved his kids, and would do anything for his friends. Hank was thrilled they had worked out. "Welcome to the family Antonio." He reached out and shook the younger man's hand, then pulled Kat into a tight hug. "I'm happy for you baby girl. ' He whispered to her, and she thanked him with a kiss on the cheek. Hank left , leaving the two of them alone .

"You really want me to stay here with you ?" Kat questioned "You don't have to protect me anymore. Ken's behind bars, and I'm sure you would like to get back to work." Antonio shook his head, grabbing both her hands and pulled her close to him.

"I wasn't kidding when I said I loved you. I know it's fast, I know you've been through a whole hell of a lot, but I would be ecstatic if you stayed with me. If you want to go back to work , go to the firehouse , whatever. I just want us to be together . I can't imagine you not being here." He didn't get to finish his sentiment before Kat was leaning in, kissing him sweetly.

"I would love to stay here with you." She squeezed him tight around the torso , and he kissed her on the forehead. They stood together for a few minutes before she pulled away and crooked her finger at him, motioning for him to join her in the bedroom. He grinned and followed, realizing he could definitely get used to this.

Their lives went back to normal – or what they could consider normal – for a good few months. It was now turning fall in Chicago . A chill was in the air, hinting that winter wasn't too far off. Ken had stayed true to his word – he didn't speak to anyone. He was charged with the murder of the two girls, but the case fell short. Even after his basic confession on the wire Kat had worn, and his DNA on the girls, the case wasn't strong enough to lead to a conviction. The day he was released Kat was there. She made sure Hank and Antonio didn't know she was planning on seeing Ken, she asked Adam to bring her instead. He reluctantly agreed, but knew he would never hear the end of it if his superiors found out.

They sat in a car across from the courthouse, waiting for Ken to come out. "Tell me Darlin, why are you doing this? You don't have to."

"I do. For these girls, for myself. If he really didn't do this maybe he knows who did . He said he would only talk to me, and I want him to talk." She crossed her arms and stared out the window of the car.

Adam nodded even though he knew she wasn't looking at him, and decided in another subject. "So how are you and Tonio doing?"

With that question she turned towards him, huge grin on her face. "So good!" the last few months had been a whirlwind. She officially moved out of her house and in to Antonio's. She met Diego and Eva, both of whom she adored. They seemed to like her too, although she wasn't sure if that was due to the desserts she made them or just her.

Adam had a hard time keeping a poker face going, he knew Antonio had planned on asking Kat to marry him, and he didn't want to ruin the surprise. He didn't have to keep it up for long, he caught a glimpse of Ken walking out of the courthouse with his lawyer. "There he is." He pointed towards the man . Kat swiveled her head to look and immediately got out of the car , jogging across the street and standing in front of him. Adam also got out of the car but waited for her there.

"I'm going to ask you to leave my client alone. He's done nothing wrong " the attorney spoke up and Ken just waved a hand dismissing her.

"She's not police. We're fine, you can go. " He gestured for the woman to leave and then he started walking, Kat following behind him. "So, does daddy know you're here?" he sneered at her. While waiting for the trial he had found out who Hank Voight was, and quickly put the puzzle pieces together of why she and Erin disappeared all those years ago, and who had taken them in.

"I came alone. You said months ago you would talk, only to me. Why?" she was genuinely curious. She had set him up, yet he refused to speak to anyone but her. "What do you want from me?"

He sat down on a bench and patted the seat next to him. "Come sit with me KittyKat. We need to catch up. " She hated that nickname and he knew it, which is why he kept using it. He wanted a reaction out of her, which he got when her nose crinkled and she sat down as far away as she could from him. "I won't bite." She just shook her head and he shrugged continuing . "That house your friends raided? Wasn't mine. Someone set me up, I'm guessing the people that I owed after you stole that oxi from me." She glanced at him, trying to gauge if he was telling the truth. "I did know those two girls, they were runners for me. But I hadn't seen them in a few days before they were found." He eased his way closer to her. "You think I would be stupid enough to leave my DNA on someone I killed?" Kat went to open her mouth and he stopped her "Don't answer that. I wouldn't be. I also wouldn't leave the bodies somewhere that could link back to me. You need to tell him… Sergeant Voight, I was set up."

"Why didn't you just tell him yourself?" Kat stared at him. It made sense, what he was saying, although Hank wouldn't want to hear it.

"After everything we have been through Katherin, I trust you." Ken was being oddly sentimental. And although Kat hated the man, he had provided her and Erin a home and food when they needed it, which was why she was sitting here listening to him.

"You stabbed me." She said in a whisper. "You're telling me now you didn't shoot me? Didn't burn down my house?"

He shook his head "I know what I did in the past was horrible, and I am truly sorry for it . But I'm not the one attacking you now. " He slid his hand close to hers, touching her fingers with his. "I swear on… whatever you deem holy that I did not do these things ."

Tears started to form in Kats eyes. She caused the intelligence team months of wasted time because she thought Ken was the one behind these attacks. Now they had a cold case, because of her. She got up , walking away before stopping and looking back at him. "If you are lying to me, nothing will save you from Hank, I promise you that."

Ken held his hands up in surrender . "I understand , but I'm telling the truth. If I can help in any way, let me know." He rose , thinking about giving her a hug before realizing that would have been a bad idea… so he just nodded at her and walked away.

Kat made her way to the car , and was silent for most of the car ride. "Where to?" she heard Adam ask her finally.

"My bakery. I need to work." She turned back to look out the window, silent again. Her mind was racing. She knew the men that Ken had worked for all those years ago, they were high up in the drug running business . He had introduced them once, a lifetime ago.

Flashback

Kat had just returned to Chicago when her life was turned upside down. She sat in the back row of the church, crying in silence as they celebrated the life of Camille Voight. She saw Justin and Hank, but didn't approach them. She also saw Erin Lindsey, her surrogate sister and best friend. Erin had caught her eye but didn't approach her until after the funeral. After the congregation had left, Kat walked to the front of the church where a photo of Camille stood. "Mom, I'm so sorry I wasn't here. I miss you guys so badly… " she heard footsteps and turned quickly to leave when she ran right into Erin.

"I thought that was you." Erin enveloped her into a tight hug. "God Kat it's been ages. How are you holding up?" she could see the woman frantically searching around the church. "Hank and Justin left for the cemetery already. You're safe, it's just me."

"Oh Er… I'm sorry I wasn't here." Kat wiped the tears away that just kept falling . "I had to get out of Chicago, it was just too much ." they sat down in the first pew and talked for hours . When Erin finally checked the time she realized Hank would be looking for her, so they exchanged numbers and a promise to get together soon. As Kat watched her go, she felt a small but of relief to be back, and joy that she could be involved in her family's lives again.

That changed immediately after Kat left the church. Pulling out into the street, distracted, she didn't see the car coming straight for her. Everything went dark, and she didn't regain consciousness until hours later in the hospital at Lakeshore.

She spent the next month in recovery for her broken vertebrae. Thankfully it wasn't extremely serious, but it did cause Kat an extensive amount of pain, which is when she got hooked on the pain killers. Her doctor refused to fill any more prescriptions after her check up came back clear of any lasting damage, so she tracked down their old "boss" Ken.

He was surprised to hear from her, but quickly took her under his wing and got her set up as a runner for his bosses. He had supplied her with enough pain medicine that she shouldn't have needed to take any more, but her body couldn't handle the pain (or so she thought). In reality it was her brain that was registering pain her body wasn't actually having , a side effect of becoming addicted. One night instead of delivering the medication as she was supposed to, she hid it. Taking what she could handle at the time she felt free. No pain. Until Ken came banging down the door demanding his pills back. Since Kat had been so high she couldn't fight back… and in his anger he stabbed her in the chest. He took off, not realizing she was still alive, although barely. Her neighbor heard the fight, called 911 and she was rushed to the hospital.

Kat went into rapid detox, which was not fun in the least. She spent a good 4 years recuperating and healing, physically mentally and emotionally, that's how bad off she was. She stayed in Chicago, got in touch with Hanks best friend Alvin, keeping him as a confidante. She opened a bakery, something she had always dreamed about . She became clean and vowed to get back to her old self, the carefree fun one. She kept in contact with Erin, but before they could get a chance to see each other Erin was transferring to the FBI in New York. They talked on the phone for hours when she made her decision, Kat thought maybe Erin wanted to be talked out of it. She kept mentioning her unit, the amazing men and women she worked with…. A Detective Jay Halstead made his way into their conversations on multiple occasions. She didn't want to leave him behind, that was going to be her biggest regret. Kat promised her that she would talk to him , if she ever had the chance to meet him, and let him know how hard this decision was for her. They hung up, knowing that they both were going to be okay.

And that was when the attacks started. For the first few weeks Kat didn't think anything of it. She played it off , thought about calling Al but decided against it. Then came the night of the fire, and it changed everything.

After the members of firehouse 51 saved her, she felt it necessary to thank them. She spent hours in the kitchen, baking batches of "Not your mommas " chocolate chip cookies (named that because of the secret ingredient in them)to bring to them. She was nervous to actually meet the men and women that had saved her, although she wasn't sure why. The nice red haired doctor at Chicago Med told her what house they belonged to, so she made her way there.

"Can we help you?" a voice made her jump as she stood in front of the open truck bay doors, lost in thought.

"Yes! Sorry, um… I'm looking for the members of truck 81, squad 3 and Ambulance 61?" she shuffled her feet slightly embarrassed she didn't know any of their names. "They saved me the other day…"

A handsome blond haired man stood up and walked towards her. "House fire on Pulaski? That was us." He ushered her inside "How can we help you?"

She looked into his eyes and almost backed out, but she stood tall and thrust the container she had in her hands towards him. "I own a bakery, and I needed to do something to thank you all." By that time There was a large crowd gathered around. Her face turned red but she continued "I brought you cookies. I really appreciate everything you did. I won't bother you any longer I just, had to thank you. " she stepped back and went to leave when she heard a chorus of "stay!"

There was a tall blue eyed man standing next to the blond haired one when she turned around . He spoke up "I'm Lieutenant Kelly Severide this is Lieutenant Matt Casey. We were the ones that pulled you out. Stay, we like getting to follow up with the people we save." He held out his arm to her and she ducked her head.

"Really? I'm not bothering you?"

They all shook their heads, most already had grabbed a cookie and were stuffing their faces. She grinned and accepted his arm. "Hi, I'm Katherin Bend, but my friends call me Kat. " They walked her back to the common room and an unlikely friendship was formed.
