A/N: I still can't believe I wrote this.
Kara loves flying at night. There's just something about weaving through wispy clouds under the pale glow of the moon that she finds immensely soothing; cathartic, almost. It's been a quiet night as far as crimes go and Kara's hoping it stays that way. She's hovering in her favourite spot that overlooks the city and from here she can see and hear everything. Kara tunes out most of the background noise: the thumping base of a club downtown, the domestic a couple are having in the suburbs and the traffic gridlock that's stalling at least a quarter of the city, if the swearing she's hearing is anything to go by – and focuses her attention on one towering skyscraper in particular. The lights on the top floor are still on, because of course Lena Luthor hasn't left the office yet. Kara rolls her eyes at woman's obstinacy to actually go home on time and speeds through the city, until she reaches L-Corp's balcony.
Kara lands on the balcony, her red boots nothing more than a dull thud against the stone floor. She gently raps on the on the glass window, smiling slightly when Lena jumps imperceptibly in her chair at the unexpected noise. Lena drops her pen on her desk as she pushes up from her chair to greet Supergirl with a warm smile, her red lipstick still firmly in place and perfectly immaculate, even after a long day at the office.
"Supergirl," Lena welcomes, leaning against the balcony door. Her white blouse is creased and her dark hair slightly mussed, but she looks beautiful. Of course, Kara knows this already because anyone with eyes can see how stunning Lena Luthor is. "What a pleasant surprise. No kittens in need of rescuing tonight?"
Kara just stands there, mouth slightly agape as her eyes finally make contact with Lena's. She's wearing glasses. Glasses. Kara's hands drop from her hips and she stumbles in her first steps towards Lena. Glasses. Lena Luthor is wearing glasses and Rao, Kara was not ready for that. Her mouth is still doing an excellent impression of a gaping fish and Lena's expression quickly turns to a frown.
"Is it my mother? Is she planning something again-"
"No!" Kara almost shouts. She clears her throat and adjusts her cape and skirt ever so slightly." No, no. Your mother has nothing to do with why I'm here. Neither do kittens actually, but you'd be surprised at how hard they actually are to get down from trees. You wouldn't know that, obviously because why on earth would you?" Kara chuckles nervously, running a hand through her golden curls. Her Kara-ness is showing. Alex would have her head, were she there right now.
Lena just stands there, her frown quickly giving way as she crosses her arms across her chest. Kara's heart jumps a little in her chest at the look Lena is giving her – amusement mixed with something else that she can't quite put her finger on, but it makes her feel warm nevertheless.
"No," Lena agrees with a wry chuckle, "I don't think I would. What can I help you with then, Supergirl? Or is this a social visit?" Lena's lips are curling upwards with barely contained delight at the sight of the fumbling superhero.
"Oh! I was just in the neighbourhood! Kara Danvers told me you were working late, so I just wanted to make sure you went home." Kara nods internally and puffs her chest out as she finishes, giving herself a mental pat on the back because that was totally a valid excuse, right? And Alex said she couldn't lie. Pff, this was easy. She still refuses to meet Lena's eyes naturally because those glasses are doing things to her that glasses should not be doing, so she fixes her gaze slightly higher. She's never been this interested in a person's forehead before, but Lena's certainly ranked in her top 3.
"Kara Danvers told you to come and check on me?" Even Kara's not oblivious to the obvious fondness that she hears in Lena's voice.
"Yes! She told me you have a terrible habit of sleeping in the office lately, so I'm to make sure you sleep in my bed- in your own, in your own bed." Kara's sure her cheeks aflame by now, but she's Supergirl. She's totally got this. Lena's a friend. A really, really good friend. And friends totally find each other attractive, right?
Lena laughs and it causes the butterflies in the pit of Kara's stomach to perform a series of somersaults that ultimately sends her heart racing in her chest.
"In my own bed, huh?" Lena says, her voice a low husk and Rao, Kara is not handling this well. At all.
"Y-yes," Kara stutters. Her hands are reaching up to fix her glasses, but remembering she's here as Supergirl, she awkwardly fiddles with a lock of her hair instead. Is it warm in here or is it suddenly really warm in here. She can't really tell.
"And Kara told you to come here?" The look in Lena's eyes is positively predatory and Kara just awkwardly stands there, wishing she'd just texted Lena as opposed to being this stuttering mess. Alex was going to kill her, while Maggie laughed.
"You didn't tell me you wore glasses!" she somehow manages to blurt out, though it sounds somewhat strangled even to her own ears. Lena blinks at her, all traces of flirtatiousness gone.
"I usually wear contacts, but I forgot to renew my prescription. Why-"
"Nothing, nothing!" Kara interrupts nervously, "I should probably go though. Kittens to rescue, people to save." She spares Lena one last glance and she regrets it instantly because now she's imagining things and her mouth goes dry. Lena Luthor in glasses looking adorably confused was Kara's new kryptonite. Yep, Alex was definitely going to kill her. Slowly. And then bring her back to life only to kill her again.
Kara walks away, without so much of another look in Lena's direction, her cheeks still blushing furiously.
"Don't forget our lunch date tomorrow, Kara!"
Kara trips off the balcony's ledge.
