This story took a different turn after I started writing it that I didn't expect, but I really like how it turned out and I hope you do too. It started as a one-shot, but I've broken it up into two chapters. Please let me know what you think with a review! :)

Insidious Attack - Chapter 1

In the early hours of the morning, just as the sun was beginning to rise over Toronto, a figure melted into the shadows within the police station putting a plan in motion. Slipping into the women's locker room, the person picked a lock exposing a freshly cleaned uniform. A gloved hand pulled out from the bag they carried a towel that had been prepared the night before, and rubbed it over every inch of the inside of the black clothing. Submersed in copper sulfate and dried, it was in diluted form, but they knew it would still have the same effects on the intended victim.

When they were finished, the uniform was adjusted on its hanger, and the locker was closed and locked, just as if it had never been touched. With an evil smile, the towels and gloves were stuffed into the bag, excited about what was to come. With silent footsteps, the figure escaped through the dark shadows knowing someone was going to pay.

It had been three days since the bomb went off and the station was still pretty much a crime scene. Evidence for other investigations still needed to be salvaged, and evidence that might help in the bombing was being collected as well. An entire section of the station was off limits until further notice, but life went on as usual.

During Parade on her first day back, Andy sat on a table in the back of the room next to Sam. She sipped the coffee he'd handed her when she walked in the room, and they listened to Oliver's announcements for the day. "You ready to be back out there?" Sam asked when Oliver dismissed everyone.

"The ringing in my ears stopped and I feel good, so yeah, I'm ready. Don't worry." She leaned in for a quick peck on the lips before hopping off the table.

"Okay, take it easy though. No heroics," he said, as her partner for the day called out to her. She nodded as she backed out of the room to meet up with Gail on the way to their cruiser.

An easy day was pretty much the opposite of what Andy and Gail ended up having. They responded to call after call, mostly minor incidents, but it lasted until early afternoon without a break.

"God, can't they make uniforms that breath better?" Gail whined as they made their way to their latest call on the unusually warm spring day.

Andy was uncomfortable too - and shifting around, she felt her shirt feeling rougher than usual; she'd have to talk to the dry cleaner about that - but she simply laughed off Gail's complaining.

"No, seriously, I'm sweating like a pig in this thing," Gail said.

"Let's just get this call over with and then head back to the station for a bit," Andy suggested as they pulled up to their destination.

They were taking statements for a parking lot fender bender when Andy noticed she was having trouble focusing and found herself feeling woozy. She rested her hand on one of the cars to steady herself.

"Hey, Andy, you okay?" Gail asked from where she was talking to one of the drivers a few feet away.

Andy nodded. "Yeah, yeah, I'm fine." She went over her driver's statement again, correcting some of what she'd already written down incorrectly.

When the drivers were sent on their ways and the officers got back into the cruiser, Andy leaned her head back and angled the pathetic air conditioning toward her face.

"You don't look so good, Andy," Gail commented, seeing how sickly her friend looked.

"I probably just need to eat something," she replied. They hadn't stopped for lunch and coupled with the heat, Andy figured it was just getting to her today.

By the time they were back at the station, Andy was feeling a little better and headed to the break room with the sandwich they'd picked up after the last call. Not having the energy to find Sam, she texted him once she sat down.

A few minutes later, Sam walked in and took a seat next to her. He immediately noticed something was up. "You feeling okay?"

"I think the heat got to me or something. Busy day, hot, no lunch. I'm fine though," she replied, trying to convince herself as much as him.

"Okay, try to take it easy the rest of the day," he suggested.

"We have so much paperwork to do, I'll be lucky to finish it by the end of shift even if I start now, so I'll be chained to my desk." Andy's eyes drifted to the two men walking down the hallway past the break room. "Why is he even still around? I don't have a good feeling about him."

Sam followed her gaze to see Inspector Jarvis and Commissioner Santana talking. "I don't know, but Oliver said he's here all hours of the day and night."

"You don't think he suspects, you know, what you're doing, do you?" Andy asked concerned. She knew what the commissioner was capable of and was worried he'd set his sights on Sam if he learned the detective was poking around.

"I haven't dug deep enough yet. But do me a favor, stay as far away from him as you can, okay?" Sam's face took on the most serious look she'd seen in a while, so she knew he was truly concerned. "If he does get wind of anything, I don't want him taking it out on you to get to me."

Andy nodded, showing she understood. "I don't get a good feeling with him lurking around the station."

"I'll talk to Oliver, see if he knows how long he'll be hanging around. In the meantime…" he said, standing up. "I gotta get back to work." He leaned down to press a chaste kiss to her lips.

"Sam." She stopped him as he started to walk away. "I know you think you're invincible and everything, but you be careful too around the commissioner."

Sam gave her a tight smile, knowing he'd do his best, but in the end he was just asking for trouble digging into the commissioner's activities surrounding the bombing conspiracy. They both knew it, but they also believed it was the right thing to do.

Andy continued with the rest of her shift, working on the paperwork for the numerous incidents she and Gail were called to. She didn't feel that bad when she was sitting, although her eyes would go blurry once in a while and she'd have to force herself to focus again. It was starting to scare her a bit, but she didn't want to overreact when it was probably nothing.

When her shift was over, Andy couldn't wait to find Sam and go home. She wanted nothing more than to cuddle up with him tonight. After changing out of her uniform, Andy walked up to the detective's office to unfortunately find the only person she had no interest in talking to.

"He went to talk to Steve Peck about a case. He should be back soon," Marlo told her as Andy perched herself on Sam's desk.

"Thanks." She could've gone to wait for Sam in his truck, or grabbed a coffee in the break room, but she sat there, staking her territory at her boyfriend's desk. She recalled a documentary she'd caught Dov watching where bears scratch trees and pee around their cave or nest to mark their territory. Andy held back a chuckle, imagining what she was doing was similar in some odd way.

Andy knew that Marlo was ordered to stay at 15 Division until the bombing investigation was complete, but it didn't mean she had to like it. Even if she and Sam were in a good place now, she didn't want Marlo ruining any of the progress they'd made the last few months. She was trying to believe it when Sam said their honeymoon phase wasn't over.

Andy's frown turned into a smile when she saw Sam walking her way. "Hey, you ready to go?" he asked.

"Yup!" Sliding off the desk, Andy got dizzy and lost her footing. Sam quickly reached out to grab her to prevent her from collapsing to the floor. "Wow, I, uh, don't know what happened," she said, rubbing her forehead. "Got a little dizzy."

"Could be some temporary vertigo from the bombing," he suggested.

She leaned against him, hoping the room would stop spinning. "The doctor said there could be some residual effects in the inner ear from the blast. I haven't felt this until today though."

"Let's get you home, see how you feel after dinner and a good night's sleep," he said, wrapping an arm around her waist.

"Yeah, I'd like that," she replied, letting him guide her out of the station.

An hour later after Andy showered and relaxed as Sam heated up leftovers from the night before, she felt like a new person. The next morning Andy woke up feeling refreshed and ready to take on a new day. To be on the safe side though, Sam convinced her to talk to Oliver about putting her on desk duty for the day.

While Sam and Andy were laughing over their morning coffee, someone was lurking in the shadows of the women's locker room. They repeated the same actions as the day before, rubbing a layer of copper sulfate onto the inside of a uniform. And taking it a step further, a black t-shirt that had been soaked in the poisonous chemical and dried, replaced the one already hanging neatly in the locker. As quietly as the person entered, they left without being seen.

Oliver agreed to take Andy off patrol for the day. She caught up on some paperwork and helped Traci search through some old case files for a connection to a current case. Her symptoms started to surface again a few hours into the morning, so Andy tried to take it easy and not let it show that she was struggling.

"How are things with Sam?" Traci asked as the two sat at a conference table, sifting through old files.

"Things are good, really good," she replied.

Traci could see something on her friend's face that told her she wasn't telling her everything. "What's wrong?"

Andy gave her friend a confused look, but gave up when Traci kept staring at her with doubt. "It's nothing. It's stupid and I'm probably crazy."

Traci quirked her eyebrows. "If it's bothering you, it's not nothing."

With a small sigh, Andy put down the file she held. "Sam and I are great. It's not like before, and we know what we want. I'm happy. We're happy."

"But…"

"But...But, I'm waiting for the other shoe to drop, for something to go wrong. I'm waiting for what's going to try and tear us apart next," Andy admitted.

"Given everything you've been through, it's not crazy to worry about that," Traci said, trying to comfort her friend.

"I love Sam with everything and I know he loves me. But it feels like things are too good to be true after everything we've been through," she said.

"Just enjoy it. Don't worry about what tomorrow might bring," Traci suggested.

"It's that easy, huh, Trace?"

"It is." Andy smiled at her friend, hoping she was right.

By the time afternoon rolled around, Andy and Traci were ready for some coffee to help them through the rest of the day. Andy bumped shoulders with another officer as she made her way to the coffee machine, and that was all it took. She lost her balance and as the room started spinning, Andy fell to the floor, hitting the back of her head on a chair as she went down.

"Andy!" Traci was kneeling next to her in a second. "Are you okay?"

"I, uh, I don't...don't know what happened," she stuttered as her friend help her sit up.

Sam, who was down the hall, had heard Traci's worried voice, and ran in their direction. He found Andy sitting on the floor looking confused. "What happened?" he asked, crouching in front of her.

"I slipped or something, I think." Andy rubbed the back of her head, trying to ease the stinging.

"She hit her head when she went down," Traci told him.

"Did you get dizzy again?" he asked, rubbing a hand up and down her arm comfortingly.

"I guess so, I'm, uh, I'm not really sure what happened. I was coming in here with Traci to get coffee and then...the room was spinning and I was on the floor," she explained. Sam and Traci helped her stand up, and Andy swayed back and forth before leaning against Sam as he wrapped an arm around her waist.

"I had a friend, I don't think it was ever this bad for her, but she found herself getting dizzy and lightheaded at the beginning of her pregnancy," Traci said, offering one possible explanation for what Andy had been experiencing. "Is it possible…?"

"No, I mean, we're not...No, it can't be. Pregnant?" Andy wasn't sure if she was worried or relieved that could be the reason for her symptoms lately.

"Whatever the cause, I think we need to get you home and make an appointment to see the doctor," Sam suggested.

Andy nodded, feeling unusually shaken up by her fall. "I'll just go change."

"I'll help you," Traci offered, and Andy let herself be transferred from Sam's hold to Traci's.

Sam sent Traci an appreciative look. "I'll go let Oliver know, grab my stuff and meet you at the locker room."

Half an hour later they were getting into Sam's truck. "What Traci said...We're careful, but it's not impossible," Andy said before worrying her bottom lip.

"You wanna stop on the way home to pick up a test?" he asked, glancing at her as he pulled out of the parking lot.

"At the very least, we can rule it out, right?" She pushed out a nervous laugh.

An hour later, Andy came out of the bathroom and sat beside him on the bed. "We have two minutes."

"Whatever it says, we'll deal with it," he told her. At one point in his life, the idea of having a child would have been the biggest disaster he could think of. He used to think that his upbringing prevented him from wanting to be a father, let alone thinking he could even be a good one. He didn't know how or exactly when, but something changed. Andy changed him into a man who looked forward to raising his own son or daughter someday. If that day was today - a bit sooner than he may have expected - he'd be okay with that.

"I don't even know what I want it to say. I mean, I should want it to tell us we're not pregnant, right? We're not ready. We haven't even talked about this stuff," she said.

"Have you ever thought about it?" he asked.

She turned her head to face him and the look in his eyes told her he had. That brought her some relief, and she nodded. "It terrifies me, but someday, yeah, I want kids, a family. And I can't imagine doing any of that without you."

Sam cupped her cheek and his thumb caressed her skin. "Good, because I want that too. With you."

"You're not scared though?" she asked.

"Terrified," he said with a chuckle. "But, you and I can do anything together."

"I love you," she whispered as she closed the distance until their lips met.

As they pulled apart, Sam tucked a stray hair behind her ear. "If we're having a baby, we'll figure it out."

Andy glanced at her watch. "Time's up."

"What are we looking for?" he asked as they walked into the bathroom together.

"Two lines means we're having a baby. One, we're not," she replied, looking over her shoulder at him. He wrapped his arms around her waist, unconsciously resting a hand over Andy's stomach.

Andy took a deep breath and picked up the stick. She didn't expect the disappointment that pinged her heart when there was only one line. She shook her head and looked at Sam in the mirror. "One line. I'm not pregnant."

Sam pressed a kiss to the side of her head. "When the time is right, we'll fill a house with kids."

Andy couldn't hide her grin as she turned around in Sam's arms and draped hers around his neck. "A house full, huh?" she teased.

"However many you want," he said, smiling back at her.

"Let's see how much I hate you after giving birth to the first one," she teased. He hugged her even closer as she buried her face in his neck, both needing a moment to process all that had happened.

When they were in bed later that night, Andy rolled on her side and traced patterns with her index finger on Sam's bare shoulder. "I was thinking…"

"That you should sleep," he quipped, as he looked at her out of the corner of his eye.

"Ha. No. That if we're talking about how many kids we're filling a house with, that, uh, maybe I should have the key to your house." She knew this was an apartment and not a house, but she hoped he understood and remembered their conversation from days ago.

He rolled his head to face her. "Really?" She nodded and Sam didn't hesitate, flying out of bed to grab the key where he left it in a box on his dresser. Climbing back into bed, he laid on his side and held the key out between them.

She wrapped her hand around his. "And if you get a cat, I'd be more than happy to come feed it."

Closing the distance between them, he covered her lips with his own. Andy hummed in contentment, but quickly rolled Sam onto his back. "You still wanna sleep?" she asked with a mischievous grin as she straddled him.

He pulled her t-shirt off as he shook his head. "What do you think?" He flipped them over, and the key he'd just given her was soon lost somewhere in a pile of clothes.

A figure sat in their car, after finishing the now daily ritual with Andy's uniform, and watched a laughing and smiling Andy get out of Sam's truck. A moment later Sam pulled Andy close and they lost themselves in a kiss. It was impossible to hear what they were saying from within the car, but the bystander found them too happy. At the very least she should be severely sick by now. The copper sulfate was taking too long to cause the serious effects of mercury poisoning. Plan B was going into effect. Andy McNally would be dead by tonight.

"Sam, come on. We're already going to be late," Andy pleaded, as she tugged him toward the door of the station.

"You're the one who said we had time for round two, darling," he teased, not at all unhappy that was their reason for being late.

"Yeah, well, you're not the one who's going to be stuck on desk duty when I'm late for Parade," she retorted.

"C'mon," he said, opening the door for her. "I'll tell Oliver it's all my fault."

Andy made it to Parade with seconds to spare, but found she was still put on desk duty. Oliver had heard about her dizzy spell the day before and insisted she get a clear bill of health from a doctor before returning to patrol.

She was in booking with Chris for the day and made it through a couple hours before she started feeling lightheaded. She fought through it, just like she'd been doing, and decided she was glad her doctor's appointment was scheduled for the next day. She just didn't know what was wrong with her.

It was early afternoon when Chris returned from locking up a suspect and found Andy staring absentmindedly at her computer, and looking pale. "Andy, are you sure you're okay? Maybe you should go home," he suggested.

Andy gave her friend a small smile. "Oh, no, I'm okay." A minute later she started feeling nauseous on top of everything else. "On second thought, um, will you be okay for five minutes? I need to get some water and use the bathroom."

"Yeah, go ahead. I'll be fine here," he replied.

Someone had been lurking around the station all day, waiting for the right time. As Andy walked toward the locker room, they saw an opportunity. Following her in, they checked to make sure no one else was around, before taking hold of their gun and hiding behind a set of lockers. They waited until Andy came out of the bathroom and went to wash her hands. A second before the butt of a gun was hit hard against the back of her head, Andy saw her attacker in the bathroom mirror.
