A/N: All fluff from here on, guys. Thanks for making it this far :) . Now, get ready for your teeth to rot
Alex updates Lena through the special between-Earths communication device by S.T.A.R Labs on the crisis on Earth X, informing her that Kara would be back on their Earth later than scheduled. Lena has a distinct suspicion that Alex isn't telling her everything for fear of worrying her, especially since Kara herself hasn't spoken to her through the device for a day now. She makes some calls and adds developing a between-Earths portal to her research team's list of priorities. She would not allow herself to be stuck here, unable to help Kara and her superpowered friends, the next time this happened.
In the meantime, she busies herself with the plan she has set into action. There is plenty to do, and she can only hope Kara is happy with the results, should she come home to her in one piece from Earth X. Lena takes a deep breath to ease her anxiety.She will.
It is two weeks later when Kara finally returns. Lena cancels everything on her schedule and rushes to the DEO immediately when Alex calls, telling her that Kara is back - that she's okay but has to rest under the sun lamps for a while. She hears the Danvers sisters bickering before she enters the med bay, and takes a long, shuddering breath, relief flooding her system.
Lena has only just passed through the med bay's doors when a blue, red and gold blur almost knocks her over, hugging her so tightly that she can't breathe. "I missed you so much ," Kara breathes. "Missed you like crazy too but I can't breathe, Kara," Lena giggles. Lena holds Supergirl at arms' length, checking her over. The Kryptonian looks fine aside from some soot and tears in her suit, and some cuts that are still healing.
Lena does not take it well when the sisters tell her what happened, that Evil Supergirl from Earth X had wanted Kara's heart - and is even madder at the fact that they are probably already telling her the sanitised version of the story. She fixes Kara with a withering gaze, and Supergirl actually steps back. "Do you know how worried I've been? You lecture me about not taking care of myself when I'm sick but you , you just run headfirst into all this danger and Kara - you could have died! Have you ever thought of how I won't be able to carry on if you're gone?" Lena looks down at her hands and finds that she is gesturing wildly. Lilian's voice is instantly in her head, telling her, Luthors stay composed . She sees Kara's kicked-puppy face and forces herself to calm down. "Please, just think about that before you jump into danger next time," Lena feels her racing heart begin to slow as Kara rubs her shoulders soothingly, whispering repeated apologies.
"Alex, I wanna go home with Lena, nowwwwwwwwwwwww" Kara whines. Of course, Alex agrees grumpily, because Alex is powerless to Kara's blue-eyed "please please pretty please" gaze, even after almost a whole lifetime of practice. Lena swallows hard, just realising now that she is always going to be just as powerless for the rest of her life . Basically, she's going to be Kara's bitch whenever she aims those baby blues at her. Damn.
Kara seems fine on the surface, but Lena catches her stumble a few times and wince in pain when she thinks Lena isn't looking. The CEO also catches her girlfriend rubbing her eyes repeatedly during the drive. They are going to Lena's apartment, where Lena has installed sun lamps because Kara hates the med bay, and the superhero does not want them in her home - does not want to be reminded of moments where she came close to losing Lena, Alex, and everyone she loves.
Lena eases Kara's head onto her shoulders and whispers, "Sleep, my love." Kara grabs the front of Lena's black silky top and buries her face in it, inhaling deeply, and in seconds, she is asleep. Lena also leans her head back and closes her eyes, sighing with relief that Kara's okay . Two weeks of sleepless nights catch up to her and she also dozes off.
Once they reach Lena's apartment and Lena tucks a freshly-showered Kara into bed, Kara kisses Lena and says, "Go back to work, I'll be fine on my own".
Lena kisses her back and smiles tenderly. "I don't have to, darling, I cancelled everything on my schedule once Alex called."
Kara's eyes widen. "Everything?!" Lena realises in this moment that she has never dropped everything for Kara before, and her heart fills with guilt.
"Yes, darling, everything. I reflected on what you said and recently made some...arrangements which I can't wait to tell you all about once you're all better. Although I can't promise you won't catch me working on my laptop while you sleep. But only while you sleep, and I'll be right next to you the whole time," Lena promises, patting the space next to her on the bed to emphasise her point. Kara looks like the happiest person on the planet as she beams, "okay," and mumbles something as she closes her eyes.
"What was that, darling?" Lena asks.
"I love you," Kara says, eyes still closed, and kisses Lena, electrifying the brunette's lips with just her touch.
The blonde then immediately falls asleep with the dopiest grin on her face. "I love you, too." Lena kisses her Kryptonian puppy on her forehead and watches her sleep for a while.
Kara drifts in and out of sleep for the rest of the day, and Lena naps next to her too, exhausted by the events of the last two weeks. Kara talks in her sleep sometimes, heartbreaking mutterings like "No, please , I have to make it home to Lena..." and "Don't hurt Alex! Take me...take me…" Lena softly strokes Kara's blonde head each time until Kara's face relinquishes its anguish. Lena realises that Kara isn't diving headfirst into danger insomuch as she is stepping in front of the most formidable enemies to get between them and those she loves.
The next morning, Kara gets up to face Snapper's wrath after being fed two weeks' worth of excuses by James. Lena makes sure her girlfriend is all loved-up before she leaves the apartment, preparing her to face the tough day.
The next day is Saturday, thankfully, and Lena announces, to Kara's glee, that she is not working that day, but needs her to meet someone in the evening. They spend the day watching movies and cuddling, completely relaxed, Kara catching up with what Lena was doing the past two weeks while trying (and failing) not to reveal anything more about the dangerous situations they got into on Earth X.
At 7pm, Lena's doorbell rings, and Lena's hand, which has been holding Kara's all day, tugs Kara up to her feet. The Kryptonian follows Lena to the door, puzzled. Since when did they greet guests together? "Please come in," Lena smiles warmly at the guest.
"Kara, I want you to meet Samantha Arias, COO of L-Corp."
Kara smiles warmly and shakes Sam's hand, confusion clouding her brow. "But, Lena, I thought you've been double-hatting as the COO for the longest time?"
"Yes, darling, but a beautiful girl has been telling me that I have too much on my plate, and I decided to listen," Lena smirks back at her, and is satisfied when Kara's breath catches. She knows her smirks have that effect on the blonde.
"Sam has been a great help to me. I'm still showing her the ropes, but in a short two weeks she's already demonstrated great capability, and I'm going to hand her half of my responsibilities at L-Corp," Lena fixes her eyes on Kara, wanting to catch her reaction. Kara's face lights up and she looks so, so proud of Lena that Lena's heart swells.
