and Calypso were good kids, and Jo would be majorly lying if she said that she didn't seriously love her job as babysitter.

She was tired of doing pointless tasks around the hospital all day. Yesterday, she'd been sent on a hunt to find Dr. Bailey a new coffee after hers had spilt. The day before that had been reserved for running off Medusa's paperwork and files.

Er...Dr. Grey. Dr. Grey's paperwork and files.

Jo's frustration had built up more than anything in the past few days. She felt like her hands were being put to waste.

But today she didn't have to do any stupid tedious tasks; she got to take it easy. Jo ate the salad that she had bought from the cafeteria as she waited in the empty locker room with the two girls. They were low-maintenance and pretty well entertained themselves while she ate.

Today, she had miraculously maneuvered her way out of scut. Tomorrow she was scrubbing in on a gender reassignment surgery. Jo figured she should stop by the corner store and pick up a dollar scratch card. With the way her luck was going, she'd win the jackpot.

"Genitals." Calypso announced quite loudly as she looked down at the front cover of Jo's textbook, brining Jo back to reality. She looked up at Jo in confusion. "What are genitals?"

Wow, the kid had a lot of questions.

They'd already been over this, though. Jo had tried to talk to Daisy about what her period meant and her changing body. But Daisy had turned so red within a minute of Jo's crash course heath class that Jo decided maybe someone else should have the talk with her, Jo was far too blunt.

"Just, uh...stuff." Jo shrugged, Calypso frowning. "Stuff" wasn't a good enough answer for her. She wanted to know more.

Jo, however, had to brush up on her anatomy before tomorrow's surgery. She had to read over a female to male gender reassignment surgery and all procedures.

Jo wanted to be as prepared as possible for tomorrow. She wanted to do everything right, she wanted to impress everyone. She wanted Dr. Sloan to go home and think, "Wow, that Jo Wilson knows what she's doing, she sure knows how to..."

Uh...handle a penis?

At least...Jo wanted to give off the impression that she knew what she was doing. She was terrified, truthfully. The closest she'd ever gotten to surgery was holding the suction while Dr. Bailey performed a cholecystectomy.

A cholecystectomy and an appendectomy were the only two Jo had ever gotten close to. And she wasn't ever the one holding the blade, always just the tray. Removing things is always cool, sure. But it's just a gallbladder removal and an appendix removal.

This was a gender reassignment surgery, completely remaking female genitals into male genitals. That had to be the coolest thing ever.

The hospital had been slow lately. Jo had heard wonders about Seattle Grace Mercy West when she was in med school.

Where was the man with the bomb in his abdomen? The guy that got mauled by a lion? The patient with the toxic blood? Those were the surgeries Jo wanted to scrub in on. The crazy, groundbreaking ones. Not appendectomies.

Jo sat at the table, tilting her textbook so that only she could see the inside. The pictures were quite visual, nothing that a six-year-old and twelve-year-old needed to be seeing.

Meanwhile, Calypso was bored out of her mind. Jo was steady reading her textbook while Daisy was steady reading that stupid paperback novel she always brought everywhere. Calypso was half-tempted to walk out of the room and go retrieve more cotton swabs, but she figured she'd be in a lot of trouble for that.

"Dais." She whispered to her older sister who shot her a glance, Calypso immediately frowning. "I'm bored."

"Occupy yourself." Daisy shrugged, to which Calypso only groaned and put her head down on the table.

She was glad that her sister wasn't dying, but she never ever wanted to come to the hospital again. It's boring.

Calypso traced shapes into the wood of the table, looking up at Jo while the woman steadily looked over the thick textbook.

"You're doing a surgery with Mark tomorrow?" Calypso asked, Jo looking up from her textbook to meet the eyes of the girl.

"Mhm." Jo nodded, flipping a page. "I have to make sure I get everything right, or else...or else I'm dead."

"Why are you so scared of him?" Calypso couldn't help but giggle. "Mark's not mean, he's nice."

Jo's face paled a bit. Was it that obvious that she was scared of the attending? Even a six-year-old was picking up on it?

Every attending scared her though, that's just the way it was. Even Dr. Robbins — the cheeriest one in the hospital — slightly terrified her, and there shouldn't be anything scary about a grown woman who wears Heelys.

"I'm not scared of him." Jo mumbled defensively. "I just...you know..."

Calypso didn't know though, and she waited expectantly for Jo to finish her thought.

Jo didn't feel the need to explain herself to a child. She sighed, turning her attention back to her textbook. She didn't even finish reading the line she had started when Calypso spoke again.

"Does it ever make you sad working here?" Calypso asked, causing Jo to frown. She closed her textbook, figuring she wouldn't be getting any reading done.

"What do you mean?"

Calypso only shrugged. "I don't know. Everyone's always sick, and...and sad. It doesn't make you sad? Daisy said she was always sad when Mom had to stay in the hospital."

Jo's frown tugged deeper at that, turning her attention over to Daisy. The girl didn't even look up though, keeping her eyes on the book as if the thought completely unfazed her.

It was silent for a moment, Daisy looking up at the lull in conversation, finally realizing that Jo was staring at her.

"Cancer." Daisy shrugged as she explained shortly.

"How long did she-"

"Year and half." Daisy spoke shortly again as she remembered her mom's excruciatingly long battle with the disease. She didn't have a problem talking about it honestly. But the sad puppy dog looks she was always given bothered her. Mom had been gone for years now, she'd grown used to the woman's absence.

Jo didn't give her a poor you look. She merely nodded, looking curious rather than pitiful.

"And you've been in the foster system for...?" Jo asked, trying to do the math in her head.

"Four years."

Ever since their dad died.

Mom had passed in January after being sick for so long. Of course Daisy had been devastated, but they had seen it coming for months and months. She expected it. And December of that same year, Dad died. His had been far worse, considering he was as healthy as ever, and a semi came out of nowhere and plowed him.

Daisy remembered feeling a numbness when her dad died that she hadn't felt when her mom passed. His death hit her like, uh...well, like a truck.

It had been four years, Daisy hoped it wasn't too soon to make that joke.

January, Mom died, and twelve months later, Dad died too — because nothing says Happy New Year like a parent's death.

Jo hoped she wasn't being too nosy by asking those questions. She didn't want the girls to think she was trying to get into their business, she was merely curious.

She cleared her throat, wanting to add some sort of commentary to give the girls a glimpse into her life instead of pushing into theirs.

"I was a firehouse baby."

Daisy tilted her head to the side, the confusion written all over her face. "A what?"

"A firehouse baby. My parents dropped me off like I was a package." Jo laughed, despite the situation not being particularly funny. "The foster system seriously sucks. I hated it so much that I opted to live in my car when I turned sixteen."

"Seriously?" Daisy asked. She hoped it never got so bad for her and Calypso that they had to live out of a car.

"You never met your parents?" Calypso asked sadly, to which Jo shook her head.

Calypso hadn't met her parents either, actually. Not that she can remember, at least. She had only been three months old when their mom got her diagnosis, a year and some when she died. She was two when her dad died, and then it was the system. Daisy was the only person she'd ever known.

Daisy thought she was lucky though. She thought it was easier that way.

Calypso didn't have to watch their mom slowly die, Calypso didn't have to sit down while a policeman broke the news that her father had been killed in a car crash. Calypso didn't have to go through any of it. She just had to follow Daisy around while Daisy sorted through all the ugly in life.

There was a gloomy silence between the three girls as everyone reminisced in their past.

Their gloomy silence, however, was broken when there was a knock on the doorframe.

Daisy looked up to see Mark standing there with a man she'd never seen before. It had been hours, she hoped they would finally get to leave the hospital. Mark was out of his scrubs and in regular clothes, so Daisy figured that was a good sign.

The man next to Mark scrunched his nose, speaking up before Mark could. "You willingly let them hang with the interns?"

Jo immediately frowned. She hated being at the bottom of the food chain, and she hated all the other surgeons treating her like scum.

"Humble yourself, Avery. You were just a resident, you're barely an attending yourself." Mark mumbled, Jackson heating up a little. He was fairly new to the whole attending thing. But still, he wouldn't call himself new, he'd been an attending for a few months now.

Mark cleared his throat, figuring he'd embarrassed the boy enough. He turned to the girls, making introductions. "This is Jackson."

Jo did find it a bit peculiar that the girls were on a first name basis with the majority of the doctors here. For instance, if Jo dared call the man Jackson as opposed to Dr. Avery, he would likely have her doing scut until her eyes were crossed.

Calypso observed the man as he gave a small wave. "Are you guys friends?"

Mark immediately responded with a "no" at the same time that Jackson responded with "yes". Jackson immediately frowned, looking hurt as he turned to face Mark.

"Joking, chill." Mark grinned, but Jackson still looked offended. "Of course we are. We're the Plastics Posse."

"The what?" Calypso was just as confused as Daisy and Jo.

"The Plastics Posse. It's what everyone calls us."

"No one calls you that." Cristina sighed as she too appeared in the doorway. She seemed to be in a rush, because she had no time for the men and their ridiculousness. The only person in the room that she regarded was Jo. "I have an aortic dissection repair tomorrow. You in?"

Jo looked stunned for a moment. "Me? You...you want me to scrub in?"

"Don't look so shocked. I need to find my new cardio godling, and the other interns are incredibly underwhelming. You could be...somewhat shapeable." Cristina shrugged, distastefully looking the girl over.

Jo wasn't all that interested in cardio. But an aortic dissection repair? That was ten times better than any plastic surgery, and one of the most dangerous surgeries Jo had ever read up on. She would get a front row seat to that?

"Oh, come on. You're not seriously gonna leave me, are you?" Mark asked, looking quite offended.

Jo found herself in quite the predicament. She didn't want to disappoint either attending, nor did she want to get on anyone's bad side. An aortic dissection repair is something Jo would do anything to witness, but she had already committed to the gender reassignment surgery.

Jo hesitated, looking at Mark before looking over at Cristina. "I'm sorry, Dr. Yang. I...I already made a commitment to Dr. Sloan-"

"Who cares? This is a cutthroat playing field, not kindergarten; you don't need to keep your pinky promises." Cristina scowled. "I'll just find someone else. Have fun with the Barbie Squad, I guess I'll-"

"No." Jo spoke firmly, shaking her head. "I...I want the surgery. I'll be there to scrub in beside you tomorrow."

"Excellent." Cristina nodded, a hint of a smile on her lips as she began to walk away.

"The Barbie Squad." Mark scoffed in disapproval at Cristina's clear jab at the Plastics Posse. "Unbelievable."

"Unbelievable." Jackson echoed as he shook his head, his arms crossed.

"Away from the traitor, children." Mark said, motioning the girls over to him. Jo couldn't help but internally groan at Mark's dramatic personality as the man looked up at her. "I'm seriously wounded, Wilson."

But nothing Dr. Sloan said would ruin Jo's mood. She would be scrubbing in on an aortic dissection repair. Even if she didn't do anything other than hold the scalpel tray, she didn't care. She would be right there to watch it all.

The girls followed Jackson and Mark out of the room. Calypso turned back, making sure to call out a goodbye to Jo.

"Bye, Jo! Good luck with your genitals!"

Jackson cocked his head as they walked. "Her what?"

Calypso still had no clue what the word meant, but she knew Jo had a fascination with them. She had an entire textbook on the subject. "Genitals. She was reading a book on genitals."

"That's...disturbing." Jackson frowned, but Mark only shrugged.

"I've heard weirder."

Daisy and Calypso walked behind the two men as they spoke, all of them leaving the hospital for the night. Daisy didn't know what time it was, but she was exhausted, and she couldn't wait to get to bed.

"Not to be weird," Jackson began to speak. "But Jo's beautiful. I mean seriously, she-"

Mark reached over to lightly slap Jackson, Jackson immediately cupping his hand to his cheek as he looked to Mark for explanation.

"Interns are off limits." Mark said firmly. "You hear me? No interns."

"But isn't that what you did with Lexie when she was-"

Another light slap. Jackson was seriously confused by this man.

"I didn't even say anything!"

"Come on, Avery. Don't talk about Lexie." Mark said it as if it were an unspoken rule that everyone should know.

"Lexie's the one that died in the plane crash." Calypso recalled quite loudly, Daisy immediately cringing.

Daisy had been thinking the same thing, of course, but she knew better than to blurt it out like that.

The group of four was now outside the hospital doors as they had been walking to the parking lot.

But Mark stopped dead in his tracks, turning to face the girl with an eerie kind of seriousness on his face. "Who told you about the plane crash?"

Jo had, actually. The woman spoke a lot, and she told the girls a whole lot of things they probably shouldn't know.

She ranted a lot about a girl named Stephanie that she was friends with. She ranted about a woman named Dr. Bailey and how she always had to get her coffee. She ranted a whole lot about a doctor that they had nicknamed Medusa, but Daisy never put two and two together to figure out who she was referring to.

And the plane crash. Jo talked a lot about the plane crash, and seemed incredibly surprised that the girls had never heard anything about it. For someone who hadn't even been working at the hospital when it happened, she seemed to know every detail.

Arizona had lost a leg, something that surprised Daisy. For a woman with a prosthetic leg, she could really maneuver well with Heelys.

Mark had been in a coma. He almost died, Jo said he was on a ventilator forever. He seriously almost died.

And...Lexie Grey. She was Meredith's little sister, and...her and Mark had been a thing.

"It was so sad." Jo had said as she frowned. "They said the plane engine had crushed her, but...she didn't die immediately, and that's the worst part. She just slowly burnt out, and Mark had to watch it. They were meant to be. Dr. Grey said she doesn't think Mark will ever even love anyone again."

Daisy was starting to believe that. He seemed defensive over the girl who had died, because his face got darker when his question wasn't answered. "Who told you about the plane crash?"

Calypso seemed slightly nervous. She didn't quite know what to say, and neither of the girls wanted to throw Jo under the bus.

"You've talked about it before." Daisy was quick to lie so that her little sister didn't choke and mention Jo's name. "We've...we've heard you talk about it before."

Daisy kind of expected Mark to get angry. She expected him to immediately call her on her bluff and scream at her.

But Mark relaxed, looking a tiny bit deflated. The plane crash was the only thing that was ever on his mind nowadays, he didn't doubt that he had somehow let that slip.

"You good?" Jackson spoke up, noticing the lack of energy in his mentor.

"Yeah." Mark slowly nodded, beginning to walk again. His thoughts were cloudy, and that was made evident in his facial expression. "Yeah. Your rhinoplasty today—how'd that go?"

Jackson didn't mind talking about the procedure he'd done two hours prior, and Mark was thankful that Jackson was distracting him.

Daisy frowned, giving Calypso a stern look. Neither girl would be bringing up the plane crash for a very long time. Never again, if they could help it.
