Erin knew it was going to be a big day the moment she opened her eyes. Sleep had been a temporary escape but now she had to face reality. Though her alarm had barely started to buzz Kelly was already gone, reality wasn't kind. It was painful to know he was annoyed, she could tell from the clattering downstairs that he was nowhere near forgiveness. A lot now hinged on a phone call. The moment she allowed herself to think about it her phone started ringing. She let out a deep sigh when she saw it was just Halstead.

"Morning" She answered, climbing out of bed.

"Good morning" He greeted cheerfully, his tone made it obvious he wanted something.

"What do you want?" She questioned, even less patient than usual. She selected an outfit and lay it on the bed.

"I'm sorry to ask but can you please give me a lift to work?" Halstead asked nicely.

"Sure" She answered before hanging up. After getting dressed she joined Kelly and Shay downstairs, his clattering had been productive and an inviting stack of pancakes sat on the table. Erin tried to start a conversation but he didn't care for small talk, he wanted answers she didn't yet have.

"Have a nice day" He muttered out of obligation as he grabbed his jacket and left. It wasn't much but it was more than she got from Shay, instantly distracted by the glitter paint Cindy had waiting. Erin couldn't help but smile, for the first fortnight after their return Shay had cried every morning. Over time she realised they weren't going to abandon her until it got to the point she didn't even fuss without a goodbye. Her adaptability was a good sign and left Erin certain they would manage if a new baby did change their family dynamic.

Completely oblivious to Erin's lack of interest, Halstead provided an embellished recount of his role in breaking up a bar fight as they made their way to work. Increasingly nervous every second she was glad for the distraction when Voight, Olinsky and Antonio led a thorough presentation of the information they had and the information they needed for their new big case. She tried to ignore the questioning looks Voight continued to throw her way. Combined with the way Burgess was sitting on the front corner of Halstead's desk the way she usually did, she couldn't help but feel she was already being replaced. Telling Voight and refusing the undercover work was in her best interests but that didn't mean she didn't already regret it. "You good for this?" Voight asked as she walked past on her way downstairs. He had assigned her and Halstead to watching Powell's back as he installed their own security cameras around the pawn shop.

"Absolutely" Lindsay assured though she couldn't lie to herself as easily. She needed to put everything out of her mind and focus. In order to do that she left her phone in her locker, that way it couldn't possibly distract her.

"Can you carry that one for me?" Powell asked gesturing to the smallest of the three crates of equipment he needed.

"Sure" She answered, watching as Halstead stacked the other two and carried them to the back of the car. At least she was still the best driver, not that she got to prove this as they made their way inconspicuously to the back of the building across the road from the pawn shop they were targeting. Powell didn't waste any time getting to work. Erin guarded the door onto the roof while Halstead lay at the edge performing preliminary surveillance and making sure the people on the street didn't notice them.

"That place is so dodgy" Halstead commented as they took the stairs down to the car and moved to the next building over. Since the operation was likely to last a while they were only saving themselves trouble by being thorough to start with. By ten o'clock they had placed a dozen security cameras and were making their way back to the district. While she tried not to make it obvious the first thing she wanted to do when they arrived was check her phone. She dawdled at her desk momentarily then decided to get it over with, if she had missed a second call she would have to call them. She picked up the phone and pressed the on button, the screen lit up to show a picture of her family. Then as she went to put it down it started ringing. Feeling like having perfect timing twice in one day was too coincidental she answered the phone.

"Hello" She answered calmly, she knew the number but didn't want to jump to conclusions.

"Erin, birthdate for results" The doctor instructed, considerably less formal the second time around.

"Eighth of July, Eighty-two" She provided without having to think.

"Your test is positive, congratulations" The doctor informed.

"Thank you" She smiled, letting all her fears evaporate for just a second as she thought about the new life they had created.

"How keen are you to see your baby?" The doctor asked.

"Um…I don't know. Why?" Erin questioned, of course she wanted to see the baby, not that there would be much to see so early.

"I can get you an ultrasound over your lunch break if your boss doesn't mind two long lunches in a row" The doctor offered. Erin had to stop and think for a moment, she'd already left Kelly out of everything, did she really want him to miss the first ultrasound as well?

"That would be great" She decided. Kelly could come to the first ultrasound when it started to actually look human, the picture might help announce it.

"It's quite early, you might get a heartbeat if you're lucky" The doctor explained making sure Erin didn't get too excited.

"Alright, I'll chat with my boss. You go ahead and organise it" She agreed trying not to let the negative thoughts back in.

"Too easy" The doctor finished. Erin put her phone in her pocket, her other hand had subconsciously come to rest over the baby. She let it drop quickly as footsteps approached.

"Lindsay, I've been meaning to talk to you" Burgess started as she got out the clothes she was wearing to the first undercover meeting, the job interview.

"Really, about what?" Erin questioned.

"Two things, firstly thank you for this opportunity and secondly I'm trying to organise baby stuff for a friend, she's a flight attendant working as much as she can early on but her boyfriends a jerk and won't do baby stuff. So basically I was wondering if you had stuff you don't need anymore" Burgess explained in her usual half nervous, half enthusiastic manner. Erin couldn't help but smile at the timing.

"I had nothing to do with you getting the job. And um…" She panicked realising she couldn't say anything about needing the baby things without giving her pregnancy away. Burgess was waiting expectantly. "I…can't help with baby things. Sorry" She finished weakly.

"Oh. I thought you have plenty of stuff from Shay" Burgess said disappointedly.

"I do…but I might need it again" She said sounding as if she was trying to convince herself as well.

"Are you pregnant?!" Burgess practically yelled, much to Erin's frustration.

"I might need it" She clarified.

"But it makes sense, with the undercover work" Burgess pressured enquiringly.

"You can't tell anybody" Erin gave in, it was as good as an admission anyway.

"Oh!…oh I won't" Burgess said, shaking her head furiously. "So nobody else knows?"

"I only just got the phone call. I've got to go talk to Voight" She explained, shutting her locker.

"This is so exciting" Burgess grinned.

"Yeah" Erin nodded less than enthusiastically as she left the room. She wanted to blame her nausea on morning sickness but it was more likely dread and guilt. She had essentially told Burgess and was about to tell Voight before her own husband had any idea. Nothing had turned out the way she had planned.

"One of the cameras has disconnected, we've got to go figure out why" Powell informed as she passed him on her way to Voight's office.

"Just give me one minute" Lindsay requested as she rapped her knuckles against the doorframe.

"Come in" Voight answered not looking up until the door clicked closed. Shutting the door always indicated as serious conversation so he put down his phone and gave her his full attention.

"I just got the results, I'm pregnant" She stated unemotively. "And I need my full lunch hour again"

"Congratulations" He said, unable to stop himself smiling at the thought of another little Shay causing trouble. "Take as long as you need" He added, assuming she was going to use the time to inform Kelly.

"Thank you" She nodded, any other boss would likely complain.

"Be careful" Voight reminded as she opened the door, Halstead and Powell waiting impatiently at the top of the stairs. She didn't feel the need to acknowledge him. Approaching the building, even with Halstead and Powell close by, she was hyper vigilant. The camera might not have been connected properly to start with or someone might have intentionally disconnected it.

"It's the one on the corner over there" Powell whispered as they stopped at the door to scan the rooftop. The massive ventilation system made it impossible to clear. Lindsay didn't trust Powell with a gun, his hands shaking just holding the weapon gave away his reluctance and inexperience. It would be safer to make him go first but it would also make him the easy target so she stepped out, looking carefully around with each movement. Powell followed closely behind with Halstead guarding his back. They reached the corner of the building, confidence that they were alone growing. Powell got to work replacing the camera, the internal wires had been purposely cut, someone didn't want them watching the alley alongside the pawn shop.

"Did you hear that?" Halstead mouthed to his partner. Lindsay shook her head, she hadn't heard a think. A second later the first gunshot sounded. Halstead reacted instantly pushing his partner behind an air conditioner unit and crouching down alongside. They didn't have time to communicate but they didn't need to. Lindsay had provided cover fire, trying to locate the person shooting at them, while Halstead stepped into the open and returned dragging Powell by the collar behind him.

"Is he alright?" Lindsay hissed.

"He's fine" Halstead nodded joining her in searching for their opponent, the needed to get off the roof. It was an extremely indefensible position.

"Sorry, I've never been shot at before" Powell explained loudly, his voice filling the silence. The familiar click of a magazine being slid into place alerted them to the position of the shooter, circling around to trap them in the corner. While it had been advantageous they both made sure Powell knew to keep his mouth shut from now on. Formulating a plan was important but with every passing second the shooter could be getting closer.

"Stay here with him" Halstead ordered finally, their hushed argument wasn't making any progress so he made an executive decision. Before Lindsay could argue he was moving away from them, towards the where the noise had come from. Keeping her gun up she followed Halstead's every move until he disappeared out of sight. A moment later there were three gunshots followed by silence. If Halstead had succeeded he would be shouting all clear by now. Pregnant or not she couldn't justify not going to her partners aid so she got Powell on his feet and led the way. She almost shot Halstead when he stepped out in front of her suddenly. Comforted to know they were together again they tried to formulate another plan. Their discussion was interrupted by the door slamming closed. Powell took it to mean they were safe while Lindsay and Halstead knew better. With increased confidence they worked methodically to clear the rows of vents. Only then did they move towards the door, confident that they were alone.

"It's locked" Powell said dejectedly when he tried the door.

"We have guns" Halstead reminded, Lindsay knew to step back while he made light work of the handle and hinges. They both knew they should call for backup, anything could be waiting in the stairwell, but neither seemed to care. Keeping close to each other they made their way down the stairs, Powell made responsible for watching the doors on the landings. Eventually they reached the exit. Other than some muddy footprints they had nothing to go on. Powell had an idea and they spent and extra twenty minutes placing a security camera where they had full view of the first one. This way they could see who was disconnecting it. Arriving back at the district Lindsay gave Voight a wave and left for her appointment. No doubt by the time she got back Halstead and Powell would have somehow incorporated a dozen gunmen and a helicopter into the story. Erin was called in straight away, feeling completely unprepared. She had planned on using the time in the waiting room to transition from Detective Lindsay, who had not long been in a rooftop shootout, to Erin, wife and mother.

"Miss Lindsay, it's nice to meet you. Can you fill me in on your pregnancy so far?" The sonographer asked.

"Well there hasn't really been a so far, I only found out for sure three hours ago. Dr Grafton worked her magic to get me in so quickly" Erin explained.

"Alright, congratulations, and how far along are you? Approximately" She questioned making notes as she spoke.

"Five or six weeks" Erin answered.

"Let's have a look then" The sonographer enthused. There really wasn't much to be seen and in the end the picture was barely worth it. A round black blob in a sea of fuzzy grey. Erin thanked the sonographer and shoved the picture in her pocket. Ready for the day to be over already she bought a sandwich to eat in the car on her way back to work. The last thing she expected to see when she arrived was her husband in Voight's office. The blinds were open but the door was closed. Fighting the urge to burst in she took a moment to calm down sitting at her desk to watch and wait. She childishly pretended to be working when Kelly emerged a few minutes later. He didn't stop to say anything so she followed him outside.

"What were you doing?" She questioned as she fell into step beside him.

"I just had to ask Voight something" Kelly explained continuing to walk, it was at this point she realised he must have walked from the firehouse.

"What?" She asked.

"Nothing to do with you" He answered.

"Kelly, please?"

"No" He refused, still walking.

"We need to talk" She said. Specifically she needed to do the talking while he listened.

"We can talk at home" He said as he stopped and turned to face her.

"I was going to drop by the firehouse after work" She suggested hopefully.

"Well don't" He instructed firmly.

"Fine" She called after him before turning on her heels and making her way back to the district. If Kelly wasn't going to fill her in she would ask Voight. Angry and tired when Voight refused to talk, instead suggesting she ask her husband, she turned to paperwork then took an early afternoon. Watching two sisters bludgeon each other at the park was the last thing Erin wanted to see but Shay was having a great time on the slide. She knew another baby would change everything but they had plenty of time to prepare. Shay would be so much older by the time it was born and would hopefully have learned to share.


Erin woke up when Kelly climbed into bed early the next morning. He usually tried to get some sleep after work, especially on weekends when they liked to do things as a family. She sat up, deciding that now was as good a time as any to talk.

"I know it's a bit late…but I have a wedding present for you" She started hoping that he would see she was making an effort.

"Really? Is it honesty" Kelly asked almost intentionally hurtfully.

"I'm trying" She pleaded.

"Okay what's the present?" He questioned.

"Maybe I shouldn't have called it a present. It's a big deal. I realise we're married and that I should have talked to you about it but I wanted it to be a surprise. Please forgive me?" She requested, laying the groundwork for the massive apology she felt the need to make.

"I can't forgive you if I don't know what you've done" He replied impatiently. At a loss for words she rolled over and took the ultrasound picture from the drawer of the bedside table and handed it to him. "What am I looking at?" He asked, taking the picture for closer inspection.

"Our baby" Erin answered calmly.

"Shay?" He questioned.

"No" She answered loving the flicker of a smile that crossed his face.

"Erin, don't mess with me" He said seriously.

"I'm not messing with you. I'm pregnant" She laughed, quickly stopping herself when she noticed the look of disbelief. "That's why I've been seeing doctors over the last few months. I wanted to do something special for you so I made some appointments to make sure I was healthy and discuss dates. Turns out our honeymoon was perfectly timed but the doctors were doubtful anything would happen first try. But it did" She explained deciding that the more information he had the more likely he was to believe it.

"You're pregnant?" He asked, feeling the need to double check.

"Yes" Erin nodded, reaching out to hold his hand.

"You've surprised me alright" He said after taking a moment to process the news.

"I'm really sorry I did it without talking to you, it is what you wanted though, isn't it?" She questioned needing him to forgive her for failing in her duties as a wife so quickly.

"Absolutely, I'm so sorry for doubting you" He replied still unable to shift the grin. "I feel like an idiot, you only found out yesterday" Kelly groaned, connecting the phone call to the test.

"This is going to change everything" She said softly.

"It is, but we're going to do it together" He nodded.

"So you forgive me?" She questioned.

"There is nothing to forgive" He assured leaning across to kiss her. One kiss turned into many as he tried to convey just how pleased he was. After pulling up her shirt and kissing her belly he returned his focus to her lips.

"So the fact that I'm pregnant turns you on?" She questioned, feeling him harden against her leg.

"Yeah" He answered enjoying every kiss. She granted him complete control, relieved he had forgiven her so easily. "Is this okay?" He questioned setting a painfully slow rhythm when he eventually decided to progress past kissing.

"No, this sucks. We've done this before and Shay turned out fine. Just be normal" Erin instructed.

"Mama?" Shay questioned, heads snapped up to see the toddler standing in the doorway looking confused.

"Shay?" How did you get out?" Erin asked, trying to push Kelly off, he didn't budge.

"Mama snuggle?" Shay asked walking towards them.

"Shay, can you go get your ball for me?" Kelly requested.

"Okay" She answered sweetly disappearing into the hallway as quickly as she had arrived.

"What the hell?" Erin questioned.

"I don't know" Kelly laughed before turning his attention back to worshipping his wife's body.

"She'll be back any second" Erin warned, conflicted between finishing what they had started and mentally scarring their daughter.

"No she won't, her ball's downstairs" He laughed speeding up his movements anyway. The prospect of Shay returning any second was disturbingly thrilling and neither of them lasted much longer.

*blushes* Had to happen eventually...
