A/N: As in previous stories I have mentioned I do not own the characters from Chicago PD, Fire or Med… only my own character of Katherin and any others I come up with. I just like playing with these characters a lot! Who wouldn't… they're divine!! Also thanks so much for the reviews!! My heart is happy. :) ps: RATING CHANGE!

Chapter 4

It was 2 am by the time Antonio got done telling the story of how and why he arrested Hank. Much to his surprise Kat hadn't interrupted once, letting him get through the entire story and not asking questions. The friends had shifted to laying next to each other on the bed during the story telling to get comfortable. "I should probably let you get to sleep." Antonio went to get up and stopped when he felt Kats hand on his arm.

"Stay." She yawned and curled up into a ball. "Like old times…" Her eyes fluttered closed, and her breathing started to even out.

Antonio smiled and turned off the light, getting under the covers he wrapped his arm around her. He kissed her forehead and felt her snuggle close to him, her hand reached up and rested on his chest, while his laid on the small of her back. He closed his eyes and was out fairly quickly .

The next morning Kat woke up to the smell of bacon cooking, and a massive headache. She stretched and rolled over, seeing a glass of orange juice , two aspirin and a bottle of water on the side table she smiled. Antonio always knew what she needed , even when she didn't know herself. She swallowed the pills, finished the juice and made her way across to the bathroom with the bottle of water. She downed the water before hopping in the shower, letting the hot water rain down on her, and she drifted back to right before she left Chicago.

Flashback

Kat lay on her stomach, sighing as she felt his finger tracing designs on her bare skin. She turned her head and looked into the brown eyes of the man she had just has the most incredible night with. "Morning" she said, smiling.

"Morning." The gruff voice responded. "Coffee?"

Kat nodded. "Sure , I can make some." She went to get up and a hand on her arm pulled her back down. She giggled as she fell back against him. "I thought you wanted coffee?"

Hank's lips captured hers, his tongue quickly invaded her mouth, stroking hers, making her moan. He rolled them so she was underneath, breaking the kiss only to begin a slow decent down her body with his lips. "I can think of something else that will wake me up this morning…" he looked up at her and then kept moving further down her body.

"Hank!" Kat moaned his name loudly as he buried a finger in her, the rough pad of his thumb running over her bundle of nerves before slipping another finger in. It didn't take long of that combination for her to see stars and call out his name . Before Kat came back down off her high he thrust himself in her, desire coursing through his veins. She arched underneath him, allowing him to capture a nipple in his mouth. Kat dug her nails into Hank's back, causing him to bite down gently before releasing hold. He sucked hard on the side of her breast, leaving a bright red mark, which he ran his tongue over trying to soothe. Hank pumped in and out of Kat, feeling her walls envelop him until they both went over the edge. A few moments of them trying to catch their breath and Hank rolled off of Kat, pulling her close to him.

"I didn't hurt you did I?" was his first question when they could speak again, his thumb running over the bright red mark he had made. He looked into her shining eyes and saw the grin on her face.

"I'm not some little breakable thing Hank. You didn't hurt me, it was perfect." She leaned over and kissed him gently on the mouth before burying her face into his chest. "I love you." She regretted it the second the words came out of her mouth, but only because of the timing. Kat had felt this way about him for awhile ,and even though they had only just started seeing each other officially, it seemed like they had been together a lot longer.

Hank raised her chin so he could look into her eyes again. His heart broke at the tears he saw forming, but he couldn't say the words back. It was too soon, and he hadn't said it to anyone since Camille. "I care about you Katie…"

She shook her head "It's okay, I understand. " She rolled over and got up, grabbing a robe sitting next to the bed, she pulled it on. "I'm going to start that coffee." She padded out to the kitchen and he could hear the kettle start.

Silently he cursed himself for saying that to her. He did love her, he had for awhile. But saying it out loud was something he wasn't quite ready for. Hank got up and dressed, and watched from the doorway as Kat moved around the kitchen getting coffee cups out. A few years prior he couldn't imagine a life without Camille. Now she was gone, and the woman in his kitchen was who his world centered around. He vowed to tell her what she desperately wanted to hear, as soon as possible.

He never got that chance.

End flashback

They had been so happy, until she got the call that changed her life. She was sent on an under cover mission that took her away from Chicago , from Hank, and almost got her killed. Kat ran her fingers over her abdomen, and the scar she had to remind her of her close call. She turned off the water that had started to run cold and got dressed quickly, pulling her wet hair into a bun, she made her way into the kitchen.

"Hey, taking care of me as always I see." She nudged Antonio who was standing at the stove with her hip. "This smells great. Thanks for the aspirin and juice, I woke up with a monster hangover."

Antonio grinned at her. "Duh. You mixed whiskey and beer. Doesn't take a genius to figure out you would be hurting today." He pointed to the table "Take a seat, it's almost ready. By the way" he said as he plated the food and set it on the table. "You know you talk in your sleep ? You didn't used to do that from what I remember during undercover work…" he winked at her.

"Oh gosh- I didn't say anything too bad did I?" Kat turned deep red.

Antonio laughed "Naw, unless you count moaning my bosses name while you're laying in my arms bad."

Kat threw a piece of bacon at him "I did not do that!" They both broke out laughing as he caught it.

"You're right , you didn't. But you did whimper and thrash a bit. Anything you wanna talk about?"

Kat shook her head, chewing on her bacon. "Nope, I'll let you know though if I change my mind." Grabbing her coffee cup and holding it in both hands she took a deep breath in closing her eyes to savor the scent. When she opened them she saw Antonio staring at her. "What?" she said then took a sip from her cup.

Antonio just grinned at her. "I haven't stayed up that late talking in a while… I also haven't slept with a woman lately." He raised an eyebrow at her "And by that I mean actual sleeping."

She threw her head back laughing. "You are such a flirt." Kat checked her watch and saw the time "Shit! Hank wanted us at the district by 8, we're gonna be late." They finished their plates in record time ,finished getting ready and headed to the district quickly after.

They showed up about 10 minutes late, and tried to sneak upstairs without anyone noticing . "Dawson! Bend! You're late." They cringed when they heard Hanks voice bellow out across the bull pen. Antonio avoided looking his boss in the eyes but Kat didn't. She had never been scared of Hank Voight and she certainly wasn't about to be now.

"Sorry boss. I was going over my notes and lost track of time. Won't happen again." She sat her bag down next to Antonio's desk and perched herself on it, waiting.

"See that it doesn't." Hank gave her a look but didn't expand on his comment. "What have we found out?"

"ME finished their prelim report. TOD is officially between 10 and 11 now. So Daniel Mendoza isn't our guy, unless he snuck back and did the job later." Jay held up the report, handing the folder to Hank. "She also said that there were signs of torture- broken fingers, missing nails, etc done to the body before the actual death." He looked at Kat "Good catch."

Kat nodded at him. "So we are looking for someone who either wants us to believe this is a mob hit, or an actual mob affiliation. Does the vic have any ties to the Latin Kings?" Kat had gotten her notebook out and started jotting down information.

"No, not that we can find. He's clean, no arrests, not even a parking ticket." Hailey answered. "We've got patrols going around to see if they can find a witness besides the neighbor that called it in, but so far they're batting zero."

Hank leaned back against his door frame watching the team volley ideas and info back and forth. He stole a glance at Kat, who was writing furiously in her notebook. His eyes skimmed her body and he saw she had chosen her outfit with purpose – a high cut blouse that covered the mark he had made on her the night before, a pair of tight jeans and boots that Erin would have loved to borrow , and he could feel the desire pooling in his stomach . Holy hell what is wrong with me? She's right I'm acting like a teenager… he caught Antonio's glance and quickly looked away.

"Okay, talk to your CI's, see if they've heard anything going around about a possible gang hit on a civilian. Halstead, you and Upton go to the vics place of employment, see if they can shed some light on what kind of individual he was." He turned to look at the board next to his office "This man was brutally murdered, we need to find out why. Katie, can I see you ?" Hank retreated to his office and stood by the door for Kat.

Kat jumped off the desk, ignoring the looks she was getting from the remaining squad members and made her way into Hank's office. "Yes boss?" she smiled as he shut the door, a drew the shade.

Hank pushed her up against the wall , growling at her. "I thought about you all last night … do you know how turned on I am right now?" he started peppering her with kisses across her jawline and down her neck.

Kat pressed her palm against the front of his jeans, causing him to bite down on the pulse point in her neck. "I think I have a guess…" she leaned into him, moaning quietly before regaining her composure. "Hank, we have to stop this." She gently pushed him making him take a step back, giving them space. "We're at work, your team is already talking about us, and you know after this they'll be gossiping even more. We need to concentrate on finding a suspect." She had to giggle at the pout he made but he didn't argue. Instead he moved to sit behind his desk, and motioned for her to sit across from him.

He knew she was right. It was crazy how Kat coming back to town had made him regress to his teenage ways, but Hank couldn't help it. The last time he had seen her she had told him she loved him, and he didn't get a chance to say it back. He hadn't been with anyone since she left, so he was past the point of needing release. "Any ideas ? I saw you writing in your notepad…" He knew she took that thing to every crime scene she had been to going back to Patrol days… it was like her own personal security blanket. He was sure she had ran out of room in multiple books by now, with as many scenes as she has visited over the years.

Kat shook her head. "No, this isn't adding up. If the victim was clean, then why would a mob enforcer be visiting his house hours before he is killed, in a very mob like manner? " She chewed on her bottom lip, thinking .

Hank had to avert his eyes. He thought about taking her lip between his own teeth, which then lead to him thinking about other body parts he could be sucking or biting on. "Katie…" his voice was low and raspy.

"Hmm?" she turned to look at Hank and realized what her action was doing to him. "Sorry." She blushed, getting up and heading to the door. "I'm going to go work on this more."

He rose and opened the door for her, not missing the fact that his bullpen was full of the unit members again. "Any updates?" he called out to the room, and was met with a chorus of no's.

Kat sat down at an empty desk and started going over everything they had found so far. She needed to see it all in front of her to understand and comprehend what had played out for the victim that night. Before she got a chance to start digging she heard Hanks phone ring, and she watched him retreat into his office to answer it. After a minute he came back out, jacket in hand.

"We got another body."
