Lena Luthor has never been the sentimental type. Sure, she has done her fair share of crying, especially recently, but she would much rather drown her sorrows in alcohol and channel all her emotions into anger. However, there is nothing quite like watching National City's being carried back to the waterfront, her body showing no signs of life. It makes Lena's heart clench in fear, fear of losing the cities hero, but mostly fear of losing her best friend.

Yes, she knows Kara Danvers is Supergirl. Well, she very strongly suspects it, she should say. She has been keeping a mental checklist of "reasons why Kara Danver is Supergirl," for a while now. A ponytail and a pair of glasses isn't the greatest disguise and does nothing to hide those strikingly blue eyes. Eyes that as Kara are sweet and inviting, and as Supergirl are strong and hold authority. The only thing that made Lena doubt her own suspicions was how different Kara's clumsy, rambling personality was compared to Supergirl's strong, demanding one.

Yet, Lena thinks of all the coincidences between Kara's disappearing and Supergirl's appearances on the news. How Kara's friend Winn will always seem to lock himself out of his apartment just minutes before Supergirl shows up saving people from a burning building. She thinks of Kara's occasional slip ups.

Lena's favorite slip up thus far was when Kara walked out the balcony door to leave Lena's office at L-Corp. Lena had smiled smugly as she watched Kara allow the balcony door to close behind her before stopping dead in her tracks and turning around with a coloring in her cheeks that rivaled that of a tomato. Kara chalked it up to being tired.

"I didn't get much sleep last night," she explained before letting out a nervous laugh. Lena made Kara think that she bought it. And told her that she needed to go home and get some rest. Without sounding too prideful, Lena is a genius. The CEO of a multimillion dollar company. She didn't become all this by being gullible.

"Supergirl! No!" Alex's cry of distress brings Lena back to reality.

Alex rushes forward to meet the Martian that is carrying Supergirl as he lands next to them. Before his feet even hit the ground, Alex is grabbing the hero's limp arm and helping guide her to the ground. She gently wipes the hair from her face with such care that it makes Lena's heart ache.

Lena puts another mental tick on her list of "reasons why Kara Danvers is Supergirl."

With the way Alex cradles Supergirl's body, how she gingerly lays her head in her lap, there is no denying that there is more to the FBI worker and the superhero. Almost like they are sisters, Lena thinks to herself. She had seen the Danvers sisters together before, their bond to each other so strong it almost made her jealous. Almost.

Lena and Kara had a bond now too though. She never would have expected it when she first saw Kara come into her office with none other than the famous Clark Kent. Yet, something about the sunny reporter always engrossed Lena. She soon found herself making exceptions for Kara. Clearing her schedule when Kara needed her, being pleasantly surprised when Kara would do the same for her. They were best friends, and Lena loved Kara. Sometimes she thought her feeling for the blonde weren't strictly platonic. But she chalked it up to the fact that she had never had such a close friend before. The blonde's presence would always make her feel safe. Feel wanted. And for once not for her money or connections. Lena loved it.

Kara had been distant recently though. It pained Lena like nothing else to see her friend in pain, grieving the loss of her lover but not allowing herself to show her grief. She wanted to help, but she felt as if she would just make it worse. She was the reason Mon-El was gone, the reason Kara hadn't given her one of those famous "Sunny Danvers smiles" in so long. Like with mostly everything bad in her life, it was her fault. Even still, Lena would be damned if she let Kara suffer anymore from something that she caused.

Taking her mind off Kara and back to the matter at hand,Lena watches as Alex hesitates briefly before reaching her fingers out to feel under Supergirl's jawline for a pulse. The world seems to stand still as she watches Alex freeze. She waits, 3 seconds, 5, 10... But there is no sigh of relief from Alex. Instead there is an increasing look of panic.

"No, no, no, no, Kara? Come on talk to me." Alex pleads with Supergirl's lifeless form. She starts lightly tapping Kara's cheek as she continues to mumble pleas to her sister.

In her peripheral Lena watches as the detective closes her eyes and shakes her head slightly. Maggie starts to move forward catching Lena's eye as she does and tries to gauge Lena's reaction. They both caught Alex's mistake even if she was too distraught to catch it herself. She just confirmed Supergirl's identity. Here was the undeniable proof Lena had been waiting on for so long. She isn't sure how she feels about the revelation. Kara Danvers, the sweet, supportive, clumsy reporter from CatCo, is Supergirl.

Studying Lena, Maggie seems satisfied that Lena will let the issue slide for now. Later, Lena tells herself. Right now, all that matters in Kara.

Getting her feet to move was hard, seemingly frozen in place by the revelation that just occurred. Maggie however, walks with purpose to Alex. She crouches down and speaks to her in a hushed soothing tone.

"She is not breathing, we need to start CPR," Maggie reasons with Alex as she makes eye contact with Lena.

She wants me to start CPR, Lena realizes. No time to waste then. She nods to Maggie as she approaches Kara's lifeless form.

Maggie drags Alex back towards Kara's legs to give her space but also stay close to Kara. There is no doubt that Alex knew everything Lena did about first aid plus some. However, she was too hysterical to put any of her knowledge to use. So, it came down to Lena to save Kara's life. Lena crouches down by the body of the Superhero, her pale skin and expressionless face so far from the usual Kara. It is crazy to think that just yesterday Kara was in her office, still dodging Lena's attempts at making plans but just as alive as ever.

Okay, I'm sorry if this makes our friendship weird. Lena thinks as she prepares herself to start CPR. Putting aside her emotions she leans over and places her mouth on Kara's, trying her best to ignore the stirring of emotion in her heart as she does. She gives Kara two breaths. Chest compressions come next. One, two, three, four, five…

Six, seven, eight, nine, ten…

Eleven, twelve, thirteen…

And she continues until she reaches 30. She reaches for a pulse. Nothing.

"Please Kara fight!" Lena screams. She isn't losing her friend. Her only friend. Her best friend.

Two more breaths and 30 more compressions later and Lena is breathing hard from the effort. She reaches for a pulse again, holding her breath while everything else in that moment fades into the background. Nothing.

"We need to get her to a hospital," Lena pauses and looks up at the other three. Tears are streaming down all their faces by now. "Or wherever you take her. Please it's not working."

"I'll take her," the Martian says with authority. "We have somewhere we can help her. Alex, Maggie, meet me there. I will fly with her, it'll be quickest that way."

Before waiting for confirmation, or even a nod, he shifts form, scoops up Kara, and takes off.
