Alright, Second Chapter already! I have absolutely been loving all the attention so thanks a heap and keep it up (I really will update faster). Still don't own CPD and I'm still a human that makes spelling mistakes occasionally :D For those of you who have been asking yes this will be Linseride.

"You okay?" Halstead asked looking at his partner with genuine concern.

"Yeah I'm fine" Erin said wondering what her partner was picking up on.

"Lindsay, you haven't had a coffee today" Halstead said making it seem like a bigger deal than it was.

"I've been busy. Working. You know the reason we're here" She responded with a knowing look.

"Sure, found him yet?" Halstead asked looking over her shoulder at the computer screen.

"Still looking" Erin said. "How about you? Got anything?"

"Nope"

"Well get on with it" She instructed watching him return to his desk and get to work. They had been looking for a drug smuggler trying to get in on the illegal weapons trade. They knew his favourite hang outs but hadn't seen his vehicle anywhere near them for several days. They'd reached out to CI's and found that no one had seen him for at least a week. They needed to find him, or his body, before they could work out his intentions with the weapons. The sound of her phone instantly grabbed her attention, she pulled it out and answered it all while heading for the back stairs.

"Lindsay, we've got Garvey's body in a warehouse on Branson, meet us there?" Antonio asked before Erin even managed to say hello. Upon hearing his voice Erin started making her way back up the stairs, it was not the call she had been expecting.

"On our way" Erin replied hanging up as she pulled on her jacket. Halstead noticed her movements and got up from his desk.

"Found his body, we'll meet the others there" Erin said leading the way to the car.

"Yes! I am so done trawling CCTV for him" Halstead said with an emphatic smile.

"I know he wasn't a good person but I still don't think its okay to be quite so excited he's dead!" Erin replied.

"Oh, sure, so you aren't pleased to be getting out of the office?" Halstead asked knowing Lindsay hated staying in all day.

"I didn't say I wasn't pleased, I just said it wasn't right" Lindsay said focusing on the road rather than her partners confused expressions. They were stopped at a red light when Lindsay's phone started ringing, without hesitation she answered it "Hello?"

"Erin Lindsay, Dr Grafton here, I have the results of your test" The doctor said.

"Okay" Erin said waiting for the doctor to give more information.

"I need your date of birth to confirm your identity"

"080782" Erin said trying to make it sound like something other than her date of birth. Halstead gave her a confused look but she was busy enough focusing on driving and talking on the phone.

"The test is positive, you are pregnant. Congratulations" Dr Grafton confirmed.

"Right, thanks. I've got to go" Erin said taking a corner slightly more aggressively than necessary.

"I've booked you an appointment next Monday night, 7:30 if that's convenient" Dr Grafton added.

"That's fine, thanks" Erin said hanging up.

"Who was that?" Halstead asked, always inquisitive.

"Who do you think would kill Garvey? And why?" Erin asked, she always tried to deflect a question before lying outright.

"Anyone with half a brain" Halstead said wondering why is partner was acting so suspiciously. Erin didn't bother to reply instead focusing on parking the car neatly behind Antonio's.

"Come on" Erin said leading the way into the warehouse. Voight, Dawson and a few uniformed officers bagging evidence.

"Shot in the head, from behind. His hands are tied and he was gagged presumably" Antonio informed gesturing to the strip of tape that had been discarded on the floor.

"Murder weapon?" Halstead asked assessing the scene.

".22 Calibre pistol, it's been bagged for DNA testing" Antonio said.

"Anything else?" Lindsay asked looking around.

"Not really, he hasn't been dead very long. Anonymous tip off reported multiple shots fired within the warehouse" Antonio offered.

"So whoever called didn't care enough to give details of the vehicle" Lindsay suggested.

"Good point" Halstead said heading out to the street momentarily. "No CCTV in the area" he reported on his return.

"DNA on the gun is our best bet, that or tracing the anonymous caller" Halstead said.

"Multiple shots but one bullet wound" Lindsay reminded.

"That doesn't make sense either, he was brought here and killed with a single shot to the head, what reason would they have to shoot more than once." Halstead replied.

"Any report on the anonymous caller, did they sound panicked? They could have been going about their business then suddenly be shot at" Lindsay said, thinking aloud.

"Ready to go? Nothing urgent, so we'll wait for DNA" Voight said approaching his team. "Back to the district to work out our plan of attack, then an early night I think" He added leading the way out of the warehouse.

"When was the last time Voight gave us an early mark?" Halstead asked once they were in the car.

"Dunno, he probably has something planned tonight" Lindsay suggested.

"Really?" Halstead asked lowering one eyebrow in a questioning look.

"Why do you always expect me to know?" she asked.

"Maybe because he's practically your father!" Halstead said surprised that it wasn't more obvious.

"Do you know what your father has planned tonight?" Erin asked to make her point, Halstead remained quiet for the rest of the drive. By the time they made their way upstairs Voight had started placing photos and information on their whiteboard.

"Took your time" Voight commented as Lindsay seated herself behind her desk.

"Sorry" Lindsay muttered looking up to analyse the information on the board.

"So in the morning we should have the DNA and ballistics reports so we'll be one step closer to catching the killer. We might try to trace the anonymous caller or at least speak to the hotline operator. Anything else?" Voight asked giving everyone the opportunity to respond. After a brief pause Voight dismissed them.

Erin headed straight for her car ignoring Hallstead's call for drinks, but headed in the opposite direction to her home. Pulling up out the front of Firehouse 51 she started to regret her decision. She'd convinced herself that delaying the inevitable never helped but now she was questioning her theory. Did she really want to dump this kind of bombshell on him halfway through a shift? Was one more night going to make any difference? Despite the fact that she has successfully talked herself out of it she still found herself getting out of the car and heading into the fire station.

"Can I help you Detective?" Matthew Casey asked looking up from his routine truck maintenance check.

"Is Severide here?" Erin asked, unable to keep the concern from her voice.

"Yeah, just through here. Is everything okay?" Casey asked looking worried.

"Every thing's fine" Erin said making an effort to sound more in control.

"Severide, visitor" Casey said leading Erin into the main room of the fire house, the kitchen. Severide sat at the long table to their left, playing cards with his friends. Seeing Erin he quickly got up looking confused. Erin thanked Casey then let Severide lead her to his office where he shut the door and turned to look at her expectantly.

"Couldn't wait for dinner?" He asked when she didn't start speaking.

"Something like that" Erin said admiring his incredible blue eyes. Now came the hard part.

"I'm sorry I haven't made more of an effort to come see you, life's been hectic" Kelly rushed to explain.

"It's fine, I've been busy too" Erin said knowing that she was stalling uselessly and should just get to the point. "Look Kelly, I..." suddenly she couldn't speak, fear of his reaction getting to her.

"Whatever it is just tell me" He said reaching out to grasp her hands.

"I'm pregnant" Erin said, aloud for the first time, her voice smaller than it had ever been. She couldn't look at him and instead stared intently at his shoes trying not to cry. He pulled her into his arms and kissed the top of her head.

"Are you sure?" He asked his voice a soft whisper.

"Yeah" She said meeting his eyes, she couldn't decipher how he was taking the news.

"I know you're going to hate me for asking, I've been messed around before...It's definitely mine?"

"Definitely" Erin replied with a nod. He could see the fear in her eyes and it worried him.

"Don't worry we can handle this, we'll work everything out" He assured pulling her closer than ever. He felt the fabric of his shirt dampen as she shook with silent sobs. "Erin, I promised you I'd stay that night, I'm promising to stay now too. Whatever happens, we'll do it together."

"Sorry, I'm being silly" She said pulling away to wipe her eyes. She took a deep breath and changed her facial expression back to calm.

"Don't be sorry" He said unable to find the words to express the way he was feeling, all he could do was pull her back to his chest and hold her tightly. After a few minutes they had both calmed down considerably. "You should head home and get some sleep. We'll talk properly tomorrow afternoon" Kelly suggested softly.

"Alright. You can't tell anyone, even Shay" Erin said trying to sound firm.

"I won't" He guaranteed.

"I must look terrible" She said wiping her cheeks in an attempt to hide the fact she'd been crying.

"You are beautiful" Kelly said thinking it was never too soon to get in a compliment.

"Sure" Erin replied sounding sceptical.

"Don't worry. Everything is going to be fine" He reassured kissing her head one last time before leading her out. He kept his arm around her shoulders guiding her through the fire station and protecting her from the prying eyes of his colleagues.

"Thank you" She said as they arrived at her car.

"See you tomorrow"

Arriving home she fixed herself a quick meal then took a shower. Feeling strangely calm she didn't even resort to putting on a movie, instead snuggling down in her bed. Relief washed over her and she wondered why she had been so worried in the first place. Carried away with fantasies of the future it didn't take long for her to drift to sleep.

Erin's PREGNANT! I'm not sure how true to her character in the show this is but I wanted to explore and develop their relationship with the added pressure of the pregnancy. I've been a fan of Linseride since Erin first appeared on Chicago Fire so I couldn't help myself…This fic will not follow the timeline and events of the current season, but I will be using some storyline from the show. Also, just to throw in another disclaimer, I am from Australia and have absolutely no clue about Chicago so I'm making up all street names etc. because I'd rather be writing than using Google Maps! Hope you don't mind…Leave me a review to let me know ;)
