Christmas Fun
Christmas Eve

Halloween wouldn't be Halloween without its customary costume party but that year, it had been discussed having it as a special Christmas Eve involving The Nightmare Before Christmas, as per Carter's request. Everyone was looking forward to it, specially since their boss would have to dress up and a bet favorite was: Sally.

Of course, Kara didn't join the game until last minute possible, "Miranda Priestly, as in The Devil Wears Prada movie's fashion icon."

Everyone groaned. It was time to close the poll and Kara had been the only one to consider it. Some thought it a waste — Kara had the inside knowledge, it was a given she would be right. James and Winn narrowed their eyes but, they doubted very much the woman would even consider speaking about a possible costume. No one could change their bets now though, yet there were others skeptical about it. Sally or Supergirl, those were the only choices most gave their uptight boss.

Kara, of course, had her costume already bought. It was obviously a fake Supergirl costume, which was the entire point of it, and with Alex's help, she had straightened her hair and already had contact lenses that darkened her eyes considerably. The curly buoyancy of her usual hair for her hero persona was something she tended to hide at work with hairdos and whatnot; it was a good counter measure, that and the heels on her boots, which made her feel as though she walked on stilettos.

"I'm not convinced Kara," Alex began, not for the first time, "your stature and build isn't something that can be faked."

"Hey, my cheek bones don't look this way!" Kara complained; whined was more accurate though. It wasn't the make up, it was something that Alex had found and thought would be useful. "Besides, my bleached roots would give them enough to talk about; they aren't going to really see me as Supergirl."

"Most people are blinded by your charming klutz nature," her sister teased. "Any chance of you not returning home and getting a date?"

"And leave you on your own, at Christmas Eve?" The alien shook her head. "No way! At most, this would end by eleven, else I'm still going to be back fifteen minutes before midnight."

"Santa might come by three am."

"Ha — ha," Kara pouted; she had always been deceived with the whole Santa debacle, at least until most of her peers began giving her weird looks. "I swear I could see — through the walls, a sleigh in the distance."

"You never saw it again."

"Hey, I couldn't fly properly back then!" She excused, still frowning. "I swear my cousin must have had something done or was involved to a degree on that one."

"Don't ruin it for Carter," Alex teased.

"I wonder if he already knows . . . ."

"I bet he thinks along your lines," the human laughed. "'It's not Santa, it's Superman!'

"Really, with the way you hang around them, I don't know if I should feel jealous." She pushed the younger woman. "Are we still sisters, or have you replaced me with that conniving woman you call 'boss'?"

But Alex only rolled her own eyes, not seeing Kara's telling blush. Honestly, she asked herself that very same question, constantly.

The party was going on well. Everyone laughed at her attempt, everyone but Cat, who only sighed at the fakeness and narrowed her eyes. Kara swallowed, thinking that maybe that was how others felt whenever she had to use her x-ray vision on them. Carter was, of course, a magnificent Jack Skelington, and completely more outgoing when she arrived, though only with her. He didn't revert back to shy whenever someone else wished to speak with him, but he adopted a reserved kind of disposition with others.

The party began at four, to give those who had families a chance to go home at six, and for those single and/or with family abroad, it went on till ten. Even if Kara had Alex, she couldn't bear the look Carter gave her at six and asked if she would leave. She couldn't.

"Oh hey, look, mistletoe!" Winn called to attention, standing besides Kara. "Do I get to kiss Supergirl?"

The double meaning was lost on everyone else as they laughed.

"Hey, not fair, I was here with her first!" Carter stated bluntly, narrowing his gaze at Winn and standing in front of Kara. "That means I should get the kiss!"

"So, you want a kiss?" Kara asked him to his ear, but it was loud enough for everyone else to hear.

Carter blushed, began to stammer a bit as Winn chuckled. Cat narrowed her own eyes as she heard that and glared at the back of her employee's head, making the young man freeze.

"You can ask me, Carter," Kara said again, looking at the boy. He simply nodded, mutely, and she just smiled softly in answer. "Okay then, close your eyes."

He did as told, and smiled in relief when he felt soft lips on his cheek. Giving him a wink, she also gave Winn a kiss to his cheek and at his pout, the boy laughed.

"There, kisses to you both," Kara teased her friend, shoving him along. Everyone left to get more drinks, laughing as they went. "You okay?"

"Yeah!" Carter replied, boyish grin still intact. "Thanks Kara! Can I get you something else?"

"No —" and he was off, probably to fill a plate again, and she could only laugh at his retreating form.

"Thank you," the words prevented her from leaving, and her sharp intake breath couldn't compare to her spiked pulse. "You treat him so well, and I don't even pay you for it."

"You wouldn't have to," Kara confessed, taking a deep breath before realizing her mistake; she blushed as she took in the scent that was uniquely her boss. "I really enjoy spending time with him."

"He is a special boy." Cat replied, looking at her son fondly before turning back to her assistant. "Well, I'm glad you opted for such a costume, even if it looks completely fake."

"I thought it would be too cliche and risky to come as Andréa Sachs," she countered with an eye roll. "Besides, I thought you dressing as Miranda Priestly was something of a long shot. The iconic white hair and do, plus Hermes' Scarf and Prada heels are most certainly a nice choice.

"I doubt I would be able to display a full Chanel couture as my assistant counterpart does in the movie."

"True but, then again, you're still long ways from being her level of assistant," Cat gave her a once over, "she's certainly a role model to look up to.

"Just don't leave me stranded in the middle of an important week in a foreign country;" she gave her employee her most devious smile, "I promise I won't be as understanding as Miranda."

She turned back to look at those inside and, in a moment of impulse, Kara did something, a rather risky something. Leaning close, she wanted to take advantage of the fact that the woman was looking away and she had perfect access to the beautiful cheek to lean in and give it a soft, tender kiss. But, Cat was Cat, she noticed the movement and turned quickly, but of course it wasn't Supergirl-fast, and Kara didn't notice until soft lips touched soft lips. Realizing, their eyes met briefly, before they closed and allowed for the connection to last a fraction longer than it should have. This meant, of course, that anyone who caught the action would gape, blink, and find out it was likely their imagination. After all, had it been true, Kara would have a handprint on her cheek, not a soft smile directed at her.

"Kara." What was hidden from prying eyes, and helped keep the embarrassed blush from their super girl, was the fact that Cat was holding her hand, tight. "We may discuss this later. Not necessarily today but, however, Carter has been looking forward to having you spend more time after everyone leaves."

She turned to look at said boy, who was making his way back at them, after carefully considering that it was polite to still bring his mother and good friend some bites to eat.

"He was talking about s'mores by the fireplace."

"Yeah, um, I — as long, as long as I can call my sister before midnight, it's a fantastic idea."

"Great," they finally released hands, "and remember, as long as it's not work related, you may call me Cat."

"That sounds, great." She clearly hesitated at that last word, but a soft hand brushing an arm took any sting from the reluctance. "Thank you, Cat, that means a lot."

"Mom!" Carter said as he returned, clearly enjoying himself. The contact between CEO and assistant was broken. "I brought these for you both."

"Thank hon."

"Agreed, thanks Carter," Kara picked one and grinned, "you brought several of these; how did you know they are my favorite?"

He only blushed, then frowned a bit. "Um, Kara, you haven't kiss my mom."

"True, but that's easily fixed," those words made Cat freeze, then she felt soft lips pressed to her cheek. "There! No special kisses from Supergirl this night!"

Carter giggled, while his mother had an unusual smile on her lips, her cheeks being softly engulfed by a rush of blood that arrived from her neck. Kara also blushed, but much more obviously and not so delicately. The temperature seemed to rise, and the air between both women seemed to charge itself. It was going to be a long night, and an even longer night after.

"Kara, are you going to a man's tonight, finally?" Alex asked over the phone.

"Alex, please don't ask," because she was staying with a man, albeit a rather young one who could get her in trouble if the suggestion her sister made was anything to go by. Not that she was opposed to such activities from said young man's mother. "I —"

"No, spending the night is spending the night!" Her sister countered, and suddenly it sounded as though a door was opened and loud music was sounding from the other side.

"Did you go out to party?" Kara gasped, frowning a bit. "Alex! What about our yearly tradition?!"

"Kara, we've been through this!" Her sister sounded exasperated. "Even when you came around through flight, just so we could continue were we left off as kids, won't make Santa any more real! I have to go now! Love you!"

The line went dead. "Yeah, all these years of tradition, suddenly dumped."

She went back to her place besides Carter on the rug before the chimney.

"Trouble in paradise?" Cat teased; it was no secret that her boss thought she had an easy life. With the wig and heels off, the woman looked incredibly comfortable in her own house and backless couture.

"Which tradition, Kara?" The boy asked, genuinely interested; she was now wearing a loaned and rather big sweater from her employer and yoga, rather short pants, and she had never felt more at home. She bumped shoulders with him, making him grin and be completely at ease. "Mom and I have one of our own."

"Waiting for Santa?" She asked ruefully, earning a gasp from the boy, and she could just grin. "Well, that's my sisterly tradition!

"I have my reasons to believe Superman helps the jolly old fellow but," she shrugged. "I keep my ears alert, my eyes wide and my nose ready."

"Cookie dough!" He cried, turning to look excitedly at his mother at the astounded nod from his companion. "See mom, I told you! He smells of cookie dough!"

"Guess we'll be hunting for him with a guest," Cat gave her assistant a rather odd smile, completely warm and unguarded, which made Kara blush, again, "you can spend the night too, if you'd like."

"I always wondered what the guest bedroom was for, once grandma left." Carter muttered, almost darkly.

"Nonsense Carter," his mother admonished. "That room isn't going to be used until we have a priest and a shaman look at it, and rid it of anything nasty my mother might have left behind."

"I swear," he replied quickly, shuddering. "Well, Kara can take my bed."

"Oh no —"

"That might be acceptable," Cat hummed, considering, "I do enjoy it when we share my bed. Makes me feel less alone."

"Not like we can do it every night," he replied, giving his mother a side glance. "Stupid shrink, I swear he has it wrong."

". . ."

The silence was almost unbearable, but mostly because Kara didn't want to interrupt their thoughts. They stared as the marshmallows finally turned into a gooey mess on a stick.

"You know, with Supergirl around, I have less nightmares," she confessed; she actually now had more, specially considering she had so many people she held dear who were possible targets, "but if it's fine with you both, I wouldn't mind spending the night."

"Not like you have someone waiting at home," Cat remarked, tone a bit scathing.

"You can always come here if you don't want to be alone," Carter supplied.

Kara smiled and brushed shoulders with him again, smiling at him. They both placed the melted 'mallows on their cookie, which was already covered by chocolate. Their actions were so similar, that Cat had a sense of déjà vu and the unsettling feeling that it was Kara, not her, who was the mother of the boy. They ate s'mores like old friends, while Cat watched with wonder. When did her assistant become so comfortable with her son, and when did her son turn so adoring of another human being? It wasn't like Carter connected with others, or didn't connect for that matter, it was more due to the fact that the boy enjoyed living in his own world. Somehow, Kara managed to enter said world and take residence.

On one hand, her son had a friend, on the other hand, it was her assistant. Cat felt that there would be conflict in the end, whether the girl went her own way, she was fired (which was still an ever present option) or was be promoted, eventually. She refused to go head first into the problem of having a competent assistant; how would she let her go in the end? It was being constantly blocked, the fact that she was depending on the girl too much, that she trusted her and said trust only seemed to grow. Those things, despite their relevance and impact, were thoughts that would prompt her into further analysis, thing she refused, vehemently, to do.

"I'll be right back!" Carter said, yawning, heading to his room.

Kara kept roasting 'mallows, and when she had five s'mores prepared, she turned; Cat was still awake. She blushed, but couldn't help the thought that the silence was comfortable, calming. Turning again, she offered the woman a perfect sandwich with gooey marshmallows and warm chocolate perfect ratio. The offering felt eternal, and after a moment of deliberation, her boss finally reached for it, almost hesitant.

"Thank you, Kara," her eyes narrowed a bit when she was given another.

"I promise, didn't poison them," the statement was done with wide eyes, earning a huff and making her grin. "I'm a superb s'more maker."

"Among other things," Cat muttered, but of course Kara heard and of course, she blushed at the compliment. She slowly ate the offered treated, smirking as she noticed the short work her assistant made of her remaining three. "I'm afraid Carter fell asleep."

"Hmmmmm," she finished her third, and looked forlorn. "Ah, must have been the chocolate. I should go —"

"I refuse to explain to Carter why you won't be here for breakfast."

"Ummmm . . . ." The message was clear. "So I'll sleep on the couch."

Cat didn't answer, just gave the young woman a half-eaten s'more before standing and moving. "I don't care if you finish it, but you'll need proper sleep ware. Camisole, pajamas, or tank-boxer combo?" She asked as she turned from her closet door; she frowned a bit. "It's just a room Kara, you can enter."

"Ok, and, mmm," she approached the closet door with caution. "Do you really have tank top and boxer combo?"

"I knew it," the woman huffed a bit, "it's what you would wear." A sigh was heard as some ruffling clothes were moved about. "They are a bit old, but we have similar body types so, it shouldn't be much problem. Here," Kara had the clothes unceremoniously dropped on her extended arm. "You can use my bathroom, there's a spare toothbrush beneath the sink. Wait for me, I need to give you a blanket and a pillow."

Kara did as told, taking her time brushing her teeth, using the toilet and washing her hands. She changed and went back to the room, feeling conscious about her ability and making an effort to not see her boss changing. The room was beautiful, but it didn't have any sitting surfaces. Taking a risk, she sat at the foot of the bed, yawning and feeling her body turn sluggish. Maybe she shouldn't have eaten that half s'more . . . .

Cat arched an eyebrow, went to her bathroom and brushed her own teeth. She couldn't deny the attraction she felt towards the younger woman, fact that only seemed to enhance itself the more she watched the interactions between her assistant and her son. A sure way to her heart, was winning her son's. It would have been easier if her initial expectation of Carter liking Kara had been met; as it was, she could hardly handle the strings her heart pulled. It was why, with a sigh, Cat coaxed the younger woman into her own bed. Clearly, it was late and she wasn't thinking straight. Not that she could, think straight, when Kara came to mind.

Sleep was blissful. Sleeping at different ends of the bed, there was no risk. Except, Kara's nightmares woke her, specially since she was sleeping in a bed which wasn't her own. As with most horrible nightmares that threatened her subconscious with kidnapping and killing those she held dear, she had to press her hand to her eyes, less she risk damaging furniture or hurting someone. She controlled her breathing, her sobs, but nothing could calm her beating heart. A whimper made her turn and at the sight, her heart constricted. Cat had been killed, before she could reach the woman and Carter, and it was clear that the woman was having nightmares of her own.

Moving, she didn't notice it was the center of the bed before she could finally reach for the other woman. Spooning, with soothing whispers and holding tight, only when the woman in her arms finally began breathing normally did Kara manage to go back to sleep herself. She forgot to dry her eyes and tears kept streaming; she would have a hard time opening her eyes come morning, but she wasn't thinking about morning, only about reassuring herself that the woman in her arms was safe, that the boy, asleep in his room, was safe, and that there was no one else in the apartment but them. Assured, Kara promptly fell back to sleep, holding Cat close and finally into a deep and fulfilling rest.
