Yes I know, another kid fic. Fight me.

"So what's happening at work today?" Lisa Snart asked her brother Leonard.

"I appreciate you calling larceny 'work'," Leonard replied.

"Hey," Lisa put her hands up, "it pays your half of the rent."

"And your half when you can't pay it."

Lisa rolled her eyes, "By the way, someone finally moved into the apartment across the hall."

"Am I supposed to care?"

"You're supposed to care long enough to say hello and then you can go back to ignoring them like all the other neighbors."

Leonard sighed dramatically and stood from the barstool he'd been sitting on.

"What are you doing?" Lisa asked.

"Going to say hello," Leonard gestured towards the door, "Isn't that what you wanted?"

Lisa shook her head in exasperation and followed him out of their apartment and to the door across the hall.

During this, Sara Lance was sorting through a cardboard box filled with clothes. She needed to leave for work soon and the shirt she'd planned on wearing was at the bottom of one of the many boxes she hadn't yet unpacked.

The process of moving into her new apartment was taking longer than expected, probably because she had to work at the same time. She'd been in her new apartment for two days now and the only unpacking she'd gotten to do was opening boxes when she needed to get something.

Just as she found the shirt (buried at the bottom of the box, just as she'd expected), she heard a knock on the door. She hurriedly pulled the grey v-neck t-shirt over her head and went to the front door.

She wasn't particular surprised that someone was at the door. Most of the neighbors on her floor had already stopped by to welcome her to the building, the exception being the residents of 3D — the apartment across the hall.

Sara unlatched the door and pulled it open. There were two people standing on the other side, a man and a woman, and judging by their similar faces, they were siblings.

"Hi," Sara said, leaning against the door.

"Hi," the woman replied, "I'm Lisa Snart from across the hall. This is my brother Leonard. We just wanted to say hello."

Sara looked the siblings over. Good genes ran in their family. They were both tall; the brother, Leonard, was at least a head and a neck taller than she was. They both had brown hair — Lisa's long, layers cascaded down her back, her brother's cropped and dotted with grey — and the same narrow, icy blue eyes and an expression on their faces that made them look permanently up to something.

Sara found it rather intoxicating, especially as Leonard's eyes met her own, giving her the feeling that he wasn't just looking at her, but reading her, understanding the inner workings of her thoughts before even she could.

She smiled.

"Well, thanks," she replied, "I'm Sara Lance. C'mon in."

Sara led Leonard and Lisa into her apartment.

"Sorry it's a bit of a mess, I haven't really had time to start unpacking yet," she apologized.

Lisa shrugged, "It's probably still better than ours."

"I wonder who's fault that is?" Leonard raised her eyebrows at his sister. Before Lisa could answer, he turned to Sara, "So what's a pretty girl like yourself doing in a neighborhood like this one?"

"Len!" Lisa rolled her eyes, "Ignore him. He's an asshole."

"No, it's okay," Sara replied, shrugging, "I'm here because it's cheap and it's pretty close to where I work."

"And where might that be?" Leonard asked.

"Down at the police precinct. I'm a homicide detective."

Leonard's eyes flashed suspiciously and Lisa sent a warning glare to her brother, daring him to say anything.

Leonard's criminal work happened under the cover of an alias, Captain Cold. That and a heavily hooded parka and goggles covering the majority of his face kept his true identity under wraps. If a CCPD detective hadn't yet made the connection, his disguise was clearly working.

"Detective, huh," Leonard finally said, "You must know Barry Allen."

Sara nodded, "Yeah, he comes along on some of my assignments and he works a lot of the forensics for my cases. How do you know him?"

"We go back a ways," Leonard replied cryptically.

If Leonard was being completely honest, he'd say that Barry Allen was one of the few people who knew who Captain Cold truly was, and the only reason he wasn't spilling was because Barry had his own secret identity, that of the red speedster, The Flash. However, Leonard was rarely completely honest, so he wasn't going to say anything.

Sara raised an eyebrow skeptically but before she could say anything, they heard the quiet pitter-patter of little feet.

"Daily bubble, Mommy!"

Leonard's head swiveled in time to see a little girl appear from a bedroom off the hallway. She looked remarkably like her mother, with big eyes a brilliant shade of blue. She had mop of thick, curly light brown hair that barely fell past her chin. Her nose was small and thin and turned up slightly at the end, She was dressed in a burnt orange jumper and cream colored blouse. On her sock-clad feet were a pair of shiny Mary Jane shoes.

Upon seeing the new people, she tucked herself behind her mother's legs.

"Don't be shy," Sara whispered, taking the girl's hand and pulling her out from behind her legs. She straightened and turned back to Leonard and Lisa, "This is my daughter, Avery. Avery, this is Leonard and Lisa. They live across the hall."

"Hi," Avery said quietly, her head tipped almost all the way up to look at the tall strangers standing in her living room

"Hi Avery," Lisa smiled, crouching down to Avery's level, "How old are you?"

"Four."

"Wow, that's so big!"

Leonard raised his eyebrows at his sister, although he wasn't exactly surprised by her behavior.

Lisa had always been good with kids, more so than Leonard at least. Kids always just seemed to like her more than him, and he didn't exactly blame them.

He tried to listen to the conversation between Avery Lance and Lisa, which he was sure was sickeningly sweet, but his eyes keep wandering to the girl's mother, Sara.

She was beautiful, Leonard couldn't deny that. She was dressed in a plain t-shirt and jeans, but the simplicity suited her. She was small, but built; he could see muscle lines on her bare arms. She and her daughter had the same deep turquoise eyes, but while Avery's eyes were wide and shining, Sara's carried a look of permanent suspicion that all cops shared.

He never would have suspected she had a kid. She was young, maybe the same age as Lisa; too young to have a four year old, especially since there was no evidence of the father anywhere.

Normally, finding out that a woman had a kid would send Leonard running, but for some reason, with Sara he didn't want to. That scared him, and if there was anything that did make Leonard run, it was being scared.

And then something even worse happened.

Sara eyes flicked from her daughter to him and her gaze met his. Leonard froze. He wanted desperately to look away, but didn't want to be the one to break the eye contact. Thankfully, his sister unknowingly rescued him.

"What's a daily bubble?" Lisa said, pulling Sara's eyes off of his.

"It's something we've done every day for a while," Sara said, looking down at her daughter. She ran a hand over Avery's hair, "We make a really big bubble and see if we can beat our record for how long it lasts before it pops."

"Wanna see?" Avery asked, her head tipped back so she could look up at her new neighbors.

"Of course," Lisa exclaimed. She stood and followed Avery and Sara deeper into the apartment. Leonard reluctantly trailed behind. If he had known what "meeting the neighbors" really ensued, he may not have been so gung ho about getting it over with.

They stepped out onto the balcony, where the only furnishing was a metal table, on which was resting a large bubble wand and a plastic tupperware container filled with a soapy liquid. Sara lifted up Avery and sat her on the table, where she picked up the container and carefully removed the lid. Sara took the bubble wand and let it rest in the liquid momentarily. Then she lifted it and dragged it through the air. The bubble that was created was huge, bigger than the size of a beach ball. It seemed to bounce through the air, it's shape changing with the wind. Avery immediately started counting.

"One…"

Sara joined in for, "two…three…"

Even Lisa added her voice to the mix for, "four…five…"

And then, silently, it popped, leaving only a few drops of the bubble liquid hanging suspending in midair for a few seconds before they too disappeared, gravity pulling them towards the sidewalk below.

"Aww," Avery said, looking to the ground in disappointment.

"What's your record?" Lisa asked.

"Eleven seconds," Sara replied. Lisa nodded.

"It was nice meeting you," Leonard said, cutting off Lisa before she had time to start, "But I've gotta get to work."

"Yeah, I probably should head out too," Sara replied, "I have to get Avery to preschool. Thanks for stopping by."

Leonard nodded once, not breaking eye contact.

"It was really nice to meet you," Lisa added, "and if you ever need anything, we're right across the hall."

"Thanks," Sara smiled. She turned to Avery, "Say goodbye to Leonard and Lisa."

"Bye," Avery said quietly, her eyes still on the sky as if the bubble would suddenly reappear, falling out of the sky from the clouds.

Sara dropped Avery off at school and continued to the police precinct.

"Lance," her boss Joe West called as she exited the elevator, "How's the new place?"

"Good," Sara nodded, walking with Joe in the direction of her office, "Haven't even tried to start unpacking yet, but good."

"Avery's settling in well?"

"Yeah," Sara shrugged, "She was a little upset when she realized we wouldn't be seeing Grandma everyday, but otherwise she's fine."

"Good," Joe said, "That's good. Look, you know how I am. If something ever comes up and you need a day off, just let me know. I'll make it happen."

"Thanks Joe," Sara said appreciatively.

"No problem, Lance. Congratulations for doing something I've been trying to get Barry to do for a year," he went to leave her office, but turned at the door way, "Speaking of Barry, he's in his lab analyzing that evidence you found from the last Cold scene. He said he'll be down to go over it with you you as soon as he's done, so I'd say you've got, oh I dunno, an hour or so to kill before he's ready."

Joe left the room chuckling at his own joke. Sara sat behind her desk and switched on her computer. She was grateful for the spare time; she had something she had to do.

Sara pulled up the police database, the system that held information about nearly every citizen of Central City.

She glanced up, her eyes swiftly passing over the precinct. When she was sure she was unwatched, she typed the name Martha Higgins, the occupant of apartment 3A and Sara's neighbor two doors down, into the search bar.

Was checking up on her neighbors morally right? No. Was it an abuse of power? Probably. But, was it justified because she was doing it with the safety of her daughter in mind? As much as Sara wished the answer was yes, she also knew that even in Avery's best interest, using the classified police database to perform background checks on her neighbors was probably not morally correct.

Sara, however, had never really cared about being morally correct.

There was nothing on Martha Higgins, nothing on the man in 3B who'd brought her a pie when they first met. Samuel Barnes — in 3C — had a few parking tickets, but they had all been paid on time. Everyone was clean, at least until she reached the occupants of 3D. Sara had a funny feeling that the Snart siblings wouldn't be as clean as the rest of her neighbors.

She was right about that.

Leonard Snart had one of the longest criminal records she'd ever seen. It began when he was twelve years old, and included a little bit of everything, from grand larceny to first degree murder to arson. His sister's list wasn't quite as long, or as diverse — she mainly dealt in petty thievery, but she had a few overlapping crimes with her brother.

Both of their records halted in late-2014. Sara wasn't entirely sure why — she'd only be accepted to the force in 2015 — but for whatever reason, Leonard and Lisa had turned away from a life of crime and never looked back.

Or so she thought.

"Don't you know who that is?" Leonard seethed, pacing across the living room, "That's the head of the Captain Cold case. We live across the hall from he woman who is actively trying to put me in jail. We have to move."

Lisa was slumped on the couch, her eyes following Leonard as he walked from one end of the room to the other.

"We're not moving," she said, "and anyway, if she didn't recognize you now, maybe she never will."

"I don't want to take that risk," he replied, "I have a bad feeling about this."

"So do I," Lisa shrugged. Leonard came to a stop in front of the TV.

"You do?"

"Yeah, you couldn't keep your eyes off her," Lisa smirked as her brother blanched, "Now move. I wanna watch TV."
