-Just a funny little part. Should be called "Cis-swapped" because gender isn't the same as sex, but "Gender swap" makes a better title-

"PLEASE?"

"Not if there are boys at the sleepover."

"Ugh! Bev! It's not like we'll be doing it at a sleepover!" Rickie groaned. "You've seen Apollo; he's not nearly as straight as he shoots! And Macson isn't really a boy, he's genderflux- plus they're too busy fawning over Supergirl."

"I said no, Rochelle." Beverly said, tapping away busily at the Batcomputer

Rickie frowned at her, Beverly could be so overprotective sometimes! She wanted to just yell that she was a Lesbian, but that would be a whole other confrontation, and she probably wouldn't get to go anyway. "What if we invite Rey, She's 18!"

"Reyna Harper is hardly a reliable adult."

"Well Red Tornado will be there, and Black Canary is there for training." Rickie argued, she REALLY wanted to go, Macson was going to paint everyone's nails and do make overs! Plus Winnie had a stack of movies and a whole box of microwave popcorn...

Beverly did trust the other leaguers, and she knew that Red Tornado and Darcey would stop any kids from misbehaving, but it was hard to believe it if she wasn't there to chaperone the children herself.

"PLEEAASSEEEE?!?" Rickie pleaded. "You owe me. The only sleepover you ever let me go to you called me back to fight the riddler."

Beverly had been hoping she wouldn't bring that up... "fine."

"YES!" She jumped, pumping her fists. "Thanks Bev!"

"I have some requirements, though, keep your phone on the whole time, answer all my texts and calls, and promise you won't get too comfortable and share things."

"Okay thank you-"

"And keep an eye on that Supergirl and MartianMaster."

Rickie restrained herself from making an 'illegal aliens' joke, she couldn't risk joking right now. "I will, Bev! Thanks!" She ran off to go pack.

------------------------------------------------------------------------

"But you'd look so good in a skirt."

"I like my clothes."

"You wear the same thing everyday, why not just try it?" Macson asked, shapeshifting a skirt. "See? You have a full range of motion!" He twirled to display that for his roommate.

"Mm." She grunted. "I like these," he gestured at her cargo pants. "they have a lot of pockets."

"UGH I KNOW RIGHT?! I have these sweat pants with HUGE pockets, it's awesome! But I can't wear them cause it's SO hot out..." Winnie perked up with a gasp. "Supes, We should get you some shorts!"

"No."

"Yes! I mean, I've got these." She gestured to her shorts, fashioned from cut-off red jeans. "And Robin has these great little green shorts- she almost never wears them because mommabats, but..." The redhead briefly lost her train on thought. "OH! We need to get you shorts, right?"

"You'd look soo good in jean shorts! Or a leotard!" Macson exclaimed, shifting into his best, slightly wonky, female human body, and trying on a few outfits.

"I like my clothes." Constance went back to ignoring their attempts.

The zetatube hummed to life behind them. "Hey guys!"

Winnie jumped off the couch. "Robin! You made it!"

"Yep! B took a LOT of convincing, though, she was worried we would be screwing or something!"

"Aww, we aren't?" The speedster joked.

"Shut up!" The bird shoved past her, grinning. "Hey 'pollo, Macs, Connie."

"Hey." Apollo slid off his headphones for a second. "You bring the stuff?"

"Yep!" Rickie opened her bag and pulled out a box of ice cream bars. "KF, pop that in the freezer, will ya?"

"Just don't pop any in your mouth..." The archer muttered.

"RUDE." Winnie suck her tongue out.

Rickie snorted, high-fiving Apollo, and flopped on the couch next to him. "How's Dad?"

"Mm." Apollo shrugged. "Same old. It was his birthday yesterday, and JayJay dropped off a gift."

"Oof." She replied.

"It was a high-tech wheelchair upgrade. He definitely stole it, but at least he left a present, Mom didn't even do that!"

"Ouch." Rickie didn't know how to reply. "Hey Kelpy!"

"Hello, Robin." Kell replied, reentering to the room, padding her hair dry in a towel. Her hair was extremely heavy on land, especially when it was wet; it was only manageable because Reyna hooked her up with a friend's sibling who could braid. "Are you excited for our sleepover?"

"Totally! This is my first-- not counting the ones with Winnie and Reyna when our mentors were working. I've been asking for one with my friend Brendon, but Bats is SO worried about mixed gender sleepovers..."

"At least she cares." Connie squirmed uncomfortably, her brow furrowed.

"Right, Let's change the subject." Apollo asked. She ignored him, but adjusted her weight and wrapped her arms around her waist, looking slightly pained.

"All good at applewood, Con?" Winnie asked. "Hey Rob, wanna pick the first movie?"

"Sure! I brought that old Grey Ghost* movie from '89! It's so campy and dumb, you'll love it!"

"Oh, I think I saw that when I was little!" Apollo exclaimed. "I can't remember if it was at the Ikea daycare place, or if a babysitter made me and Jay watch it, but I vividly remember the bad puns..."

"You must be thinking of GreyGhost Forever, the second sequel." Robin explained. "Don't worry, I brought the entire quadrilogy!"

"Oh yeah, they're the worst!" Winnie agreed, leaning against the shortest girl. "It's great, I highly recommend them, unironically!" She said ironically. "Marathon night?"

"Duh!"

------------------------------------------------------------------------

"WHOO!" Macs'n clapped emphatically. "I loved the special affects! They're really good!"

"No they aren't," Winnie goaded. "you're only impressed because it's better than in the seventies!"

Kell frowned, shifting off the sofa and into the blanket nest that had manifested on the carpet. "I'm confused,  What happened?"

"Simple, Kelpy: The Grey Ghost uses his grappling hook to attach the baddie's leg to a gargoyle, and he falls to his death while Grey and his lady friend make it to safety*."

"No, I saw that." She said. "I don't understand the movie..."

"Welcome to the club. That's what makes them awesome!" Winnie cackled, chucking some popcorn. "Rob, but on the next one while I get some more snacks!"

"Alright! GreyGhost Returns coming right up!"

"Nice! Hey Supey," The redhead nudged her where she was sprawled on the sofa.

"Mhm? What?" She squinted up as Kell turned on the lights.

"You want anything-- OH! Uhh... Supes..." A blush started to steal over Winnie's freckles. "You uhh... lets go to the bathroom for a moment."

Constance frowned. "Why?"

"Just, uh..." the redhead's face turned darker with embarrassment. "You... you... Let's just talk for a minute."

"Okay."

"Like, in private."

"I can set up a link if you guys want?" Macson offered, standing and dusting crumbs off his lap

"NO!" Winnie exclaimed. "but, Con, maybe we can head off to the side, and..."

"Winnie, Whatever you're Doing, it's REALLY conspicuous." Rochelle laughed. "What's up?"

"It's just... uhh... you're sorta... bleeding." She squeaked out half-hiding in her hands.

"What?" Connie looked over her arms and felt up her face and neck, confused; she's kryptonian, how could she be bleeding?

Apollo's look of mild bemusement disappeared, he slapped his hand over his mouth, eyebrows shooting into his hair. "Supergirl, you're bleeding down there."

Connie looked down at her legs.

"No, Con..."

The supergirl caught a whiff of blood and perked up, her eyes scanned every visible part of her, stopping at the sight of red staining the crotch of her trousers.

Instinctively, she let out a yell, shooting backwards off the carpet. How was she bleeding? Was it internal? Were her friends going to start bleeding too? Maybe she should call Black Canary, he'd know what to do...

"Whoa, calm down, it's just your period." Rickie said.

"What?" A period? Like a full stop, or a length of time? What did that have to do with blood?!

"Calm down, Friend." Kell stood and held Connie's shoulders to sooth her. "It is your, uh..."

"Like, mensuration." Robin said.

Menstruation, that was a word her knew: 'the monthly shedding of the lining of a female's uterus (more commonly known as the womb).' She knew of ovulation, and fertility, but had never thought she'd have it!

"But I've been alive for almost four months and I've never experienced this!"

"Hey, It's okay. The same thing happened to me in gym class, last year..." Rickie admitted. "It's nothing to freak out about."

"Yeah." Apollo said, clearing his throat and looking away. "I mean... I've overheard GA and Reyna talk about it, and they said that's not a big deal if you know how to manage it, so..." he blushed, feeling more scandalized than he should.

"Do you guys have any pads around the mountain?" Winnie asked.

"No? What are pads?" Macson asked.

------------------------------------------------------------------------

"God, I can't believe you dragged me out here." The exhausted Reyna grumbled, stalking after her obnoxious little 'brother'.

"Shut up, you weren't sleeping anyways!"

Rayna yawned and slumped over to the kid. "First time?" The doe eyes gave it away. She pulled two half-empty boxes out of her bag. "These are pads, they stick to the inside of your underwear, you bleed onto them. These are tampons, they go up there, Winnie can show you how to use them-"

"NO I CAN'T!"

"You're going to have cramps and cravings and acne and (bigger) mood-swings and stuff until this is over."

"How do I fix that?"

"You don't, you just wait it out for a week ...but I dunno, krypton-periods could be, like, two months for all I know."

Connie considered that, none of them knew what kryptonian menstruations were like... Maybe that would be a good excuse to finally talk to Superwoman!

"There: I talked to her, now never call me again!" The eighteen-year-old prodded Apollo in the chest.

"Thank you!" Macson called, waving after her with a big friendly smile. "There's pizza and soda in the kitchen if you want some!"

"Don't offer her pizza for doing the minimum!" Apollo said, offended.

"Minimum?! I came all the way to your clubhouse at 12:15am to give all my pads away and explain vagina blood to a four month old!"

"You didn't even explain anything! You basically just gave her the stuff and said 'figure it out'!" The blond scoffed.

"Like you know more than me?" Reyna rolled her eyes at him, biting into a slice of butter-chicken pizza. "You're such an ungrateful little shit. Wait till Ollie hears about this!"

"Olivia would be on MY side! She'd understand that Supergirl deserves that knowledge, because Ollie is a good hero!"

"Oh, and am the bad, mean superhero, huh?" The redhead snorted at her replacement/little brother's comically righteous fury. "Take it up with the complaints department, bub."

Apollo scowled as she polished off her slice of pizza and started on another. "You're not even part of the team! You can't be at our sleepover!"

Reyna covered her mouth, snorting into her hand. "Aw, am I not invited to your birthday party? Whatever, I'm taking the rest of the pizza."

"Hey!" Winnie whined, but it was too late, Reyna escaped through the zetatube.

Apollo growled. "I CAN'T STAND HER!!!"

"You guys want me to rewind the movie?" Robin asked. "We've still got time to Marathon."

"You do that, I'll assist Supergirl with figuring this out." The Atlantean steered her away.

"Kelpy, do you even bleed?"

She turned pink. "Not externally, Our menstural blood is reused internally...."

Robin stood, stretching, and took Supergirl's arm from the team leader.. "Put on the movie, Winnie. I'll figure this out with our friend."

"Okay." The speedster gave a sigh of relief. "Thank you bestie."

"Yeah, yeah..."

------------------------------------------------------------------------

"Since it's your first, let's stick with pads." She explained, directing the ever bewildered Constance on the  (What should be) simple process of pulling down garments, affixing pad, and pulling up the same garments. Rochelle wondered how the hell Connie managed to dress herself in the morning. 
"And you have to change it when it has too much... y'know."

"How often will I have to change it?"

"I don't know! Twice a day? More of less depending on how much you--" Her phone rang. "UGH! hold on!" Halfway through directing Superboy, she whipped out her phone. "Hi, B! All's well! Don't worry!"

"...Why would I need to worry?" Beverly asked. 

"You don't!" She replied. "It's all going great, we're watching a movie! Reyna even dropped by!"

"Where are you now?"

"Just--"

"Robin?" Supergirl asked, full volume, as always. "You didn't finish your sentence."

"Who's that?" 

"Just supergirl. We're on a bathroom break.

"You didn't finish what you were saying." She continued, irritated by the lack of acknowledgement. "Robin? Robin? Robin?"

"It depends of how much you BLEED!" She snapped, turning back to her phone. "We're all good here."

"What depends on how much you bleed?" Her mentor asked, almost urgently. "Rickie?"

"LOONG Story-- Inside joke-- gotta go, bye!" She hung up, letting out a shaky exhale, sliding her phone back in her pocket.

Supergirl, who had gone quiet again, glared up at her again. "Don't yell at me."

"Sorry, Connie, that was just Batwoman, things are awkward, y'know." It was abundantly evident that she didn't, so Rickie moved on. "C'mon, let's catch the movie ...but, like, maybe put on your clothes first."

------------------------------------------------------------------------

"Robin..." Rochelle tossed around, light fading into view.  "...Robin..." She rolled over onto something boney and fleshy; a friend. She rolled off them. "Robin!"

"What?!" She sat up sharply. the overhead lights were on, but the pillow nest was still bathed in darkness. Batwoman faded into view over her. "B? What?"

"You didn't pick up you're phone."

"I was asleep! It's called a sleepover!" Rickie pulled out her phone: five-twenty am. "What did you think I'd be doing?"

Batwoman didn't reply. She turned to leave. "Get some sleep, you have patrol tonight."

Rickie watched her leave, flopping back onto the blankets. Beverly was going to be the death of her!
