I love you but I just can't tell you everything (a supercorp fanfic)

Save her!

I quickly rip of my glasses and rip my shirt of revealing my s logo, the s logo that forever lives on my supergirl suit, I quickly get undressed and into my suit, I fly out and round to the balancing where Lena is running to after being ambushed by some weird people, people who I assume work for Cadmus, a company that is run by Lena mums. I land on the balcony and Lena looks at me and she winks and grips onto me, I turn around and Lena waves at them and then I jump of the building, we are falling for a few seconds but it feels like hours manly due to the fact that it feels as though it's going in slow motion.

Then suddenly after Lena's short second of screaming I fly up and we pass the other guys knocking them over due to the Air Force and resistance I produce why I'm flying. Lena starts laughing the moment we fly past them and they fall. Lena finds it hilarious and to be honest I go to, i then drop her at a coffee shop then I fly of and quickly land just around the corner in an ally way where I get changed and put on my normal clothes and classic Kara danvers glasses. I then walk around and I run into Lena, I act as though I've not just rescued her when actually I have,
"Lena hey" I say and I hug her
"Hey Kara omg I was attacked and like supergirl saved me anyway we will talk about it over coffee that I will buy." Lena says and I nod heads, after all I never refuse a coffee brought by my best friend,
"But can we get take out I have to return to CatCo." I say and Lena nods her head,
"Yeah I have so much work to do, so we can have a chat in my office and then we can do some work" Lena says as she pushes open the door into the coffee shop and we walk in and get in the queue,
"What coffee you want?" Lena asks and I look at the menu, hot chocolate or latte,
"Ohh I'll have Umm a hot chocolate please Lena" I ask and Lena nods her head and walks up to the counter as it's our turn to order,
"2 hot chocolates please with  extra whip cream and marshmallows on both" Lena says and I laugh, I do love marshmallows and whip cream, they take our order and make it and they pass the drinks to us and Lena pays and I give a tip of £1 into the tip jar that has the word tips written on in terrible handwriting that's barely readable.
"Thanks" I say to Lena as she passes me the drink in it's coffee cup, we walk out and summon a taxi and we climb in and Lena tells it to drive CatCo world wide media and the driver nods his head and the radio plays, the song on is one of my favourite songs and it's Lena's to after all best friends are alike. We then start singing the song, it's literally a full out karaoke session in the back of this taxi. My sister, alex does say I put the Kara in karaoke, in other words I'm good at singing and to be honest she's not the only one who's told me that, Barry Allen, well the flash I guess you may  know him as, when we were trapped in a musical, long story, then when we got out he told me that i was a good singer.

Soon we arrive at CatCo and we climb out the taxi, I give him some money and he takes it and  drives of, so we walk into the lift and up to the floor, floor 28, we then walk into Lena's office, and all sit down on some sofas and I sip the hot chocolate that's still nice and warm.
"So What happened?" I ask and suddenly I find myself coughing, coughing over and over again.
I grip onto my throat it hurts, and I'm coughing and spluttering over and over again,
"Kara! Kara! Are you okay?" Lena yells at me as I cough an splutter over and over again. I fall to the ground and in seconds Lena is next to me,
"Kara! Kara! What's going on?!" Lena yells and she grabs my hand
"Ring alexxx" I say as I try to grip onto me life, but I'm struggling, I try to stay awake, alive basically but I can't. And soon my fight is over and I pass out on CatCo floor.

—Lena's point of view—

I grab m phone and dial Alex,
"Hi this Alex, who's calling?" Alex's voice says through the phones speaker,
"Oh yes hi this is Lena Luther and I'm calling form CatCo, it's about Kara she's just collapsed on the floor and I have no idea what to do please get down here now I don't know what to do" I say with worry and pain in my voice. I feel Jittery and absolutely terrified, I have no idea what's wrong with Kara and then I look down  and her glasses fall off her face and then I see it, she looks just like supergirl, as In exactly like her, I don't know why but I feel as though I have to open her top and I do, I unbuckle each button, and I can see a blue top under, but it's when I find the s logo that I know she's been lying to me, lying to me ever since we met, I can't describe what i feel right now, there are literally no words for it. It's a betrayal but at the same time it's not, I don't even know what to do, I'm stressing, I'm nervous and I'm upset, I'm betrayed. I'm simply betrayed by my well what was my best friend, I don't know any more, what to say or what to do. So I step back, I turn away from where she lay on the floor and I stare at the images of  supergirl saving people that flash on the CatCo screens and I think that's my best friend, that's Kara danvers, the pretender, I guess, I can't help but feel angry, upset and annoyed but at the same time I'm terrified as I turn quickly and glimps at her almost lifeless body as it lay on the floor, but dread and guilt build over me making me immediately turn back around to the screens praising supergirl.

Soon alex runs in but I'm to transfixed by the screens to even notice her until she walks up to me,
"Lena, are you okay?" Alex asks as she puts a what's meant to be a comforting hand on my shoulder, I shrug it of, I think alex knows about her being supergirl, another person that has lied to me.
"I know Kara's secret," I say and Alex looks at me and starts shaking her head, obviously worried that I know her 'secret identity'
"I know she's supergirl" I say and Alex turns her head and looks at Kara she doesn't say anything and just walks of, she walks over to Kara and holds onto her hand, obviously begging that she will hang on, that she will love and I hope for that to, but in some dark, dark ways I kind of hope she won't wake up, I know she will try to convince me that she was going to tell me she just didn't know when, or that she isn't what I have proof of, and for some odd reason I can't face her, because even though she lied to my face dozens of times, she is still my best friend, my very best friend....
