The Problem is the Blood!

"Lena.... what?" Kara asks, confused.

Lena runs over to the transfusion machine and quickly turns it off, not bothering to explain it to anyone. Lena just needs to stop the transfusion as they are killing Alura with Kara's blood. Lena then turns to Alura with an attempt at a reassuring smile and carefully takes out the tube which was putting Kara's blood into her Alura's body.

"Lena? What's going on." Kara asks, very worried.

"Not now Kara. Eliza can you get me a cotton swab and a plaster to cover up the puncture wound?" Lena asks as she begins to take out the needle head which is in Alura's arm.

Eliza nods in response and quickly runs over to the other side of the room and grabs everything that Lena asked for and then returns and gives them to Lena. Lena carefully wipes away any residual blood, not wanting any more of Kara's blood to even have a tiny bit of a chance to get inside her, enough damage has already been done.

"'Ena?" Alura now asks, looking up at Lena with a worried look on her face.

"It's okay Alura. It's going to be fine." Lena tries to reassure her, doing a very bad job of it. Lena then turns to Kara. "Kara, I need you to get Alex, now."

Kara hesitates for a second but then nods and zooms out of the room, returning with Alex.

"Kara!? What the...." Alex says and then notices Lena standing looking worried over Alura. "What's happening?"

"I know what is wrong with Alura. I'm 90% sure. I just need another blood sample to be 100%. But, what I am sure about is that Kara's blood was....." Lena begins, but then looks at Alura, "not..... helping."

Kara lets out a gasp, clearly understanding that 'not helping' was just putting it lightly.

"Then what is going on Lena? What have you found?" Alex asks.

"I didn't know that Alura's blood type doesn't match Kara's, or match anyone's blood type for that matter. After you told me I began comparing Kara and Alura's blood types. I believe that the reason you could not match Alura's blood type to anyone else's is because it's two blood types combined. One human, one Kryptonian, one for the mother, one for the father." Lena explains.

Kara looks at Lena shocked. Meanwhile Alex and Eliza both give each other worried looks, clearly upset and angry and disappointed at themselves that they didn't catch this.

"So.... what does this mean?" Kara asks.

Lena turns to look at Kara.

"I'm not sure yet. I have a theory.... but..... to prove this theory I'm going to need a new blood sample...." Lena says as she bites her lip.

"Okay.... I can get another syringe to draw a sample." Alex says and begins to walk to get a syringe.

"It's not that simple." Lena says, stopping Alex in her tracks.

Eliza goes wide eyed as she looks at Lena and then looks sympathetically at Alura.

"What's not simple?" Kara asks, not understanding.

Lena turns to look at Kara and takes a deep breath. This explanation isn't going to be a nice one. Hell, everything that's going on isn't nice.

"Kara, we can't draw blood from Alura's arm because of the transfusion..... I need a clean sample of her natural blood type. Drawing from the arm or legs would give us an unbalanced mixture of both of your blood types. I need a..... direct source...." Lena explains.

Kara gasps again. Meanwhile Alex just looks at her niece with tears in her eyes. This next thing that they have to do is probably going to scar her for life.

"You mean....." Kara begins, tears also in her eyes.

"Yeah...." Lena nods.

Everyone is silent for a moment, shocked by the information.

"'Ena? What's happening?" Alura looks up at Lena with concern on her face.

Lena looks at Kara for approval to explain it to Alura and Kara just gives her a nod. Kara is turned away from her daughter, not wanting her to see how scared she is for her. Lena then approaches Alura's bedside and crouches down beside her and strokes the top of the young girl's head.

"Darling, I'm going to need to draw more blood..... and to do so...... I need to draw it ...... directly from your heart....... with a large needle..." Lena explains.

Alura looks up at Lena and looks terrified. Lena just takes Alura in her arms and hugs her.

"I'm sorry. I'm so sorry." Lena says as Alura remains still in her arms.

"Can we..... put her under?" Kara asks.

"No honey." Eliza replies.

"Okay...." Kara nods, scared.

Lena turns to look at everyone else.

"I hate to say this.... but we really need to do this quickly." Lena says.

Alex gives Lena a nod and turns around to retrieve the correct longer needle and syringe. Lena just carefully lays Alura back down on the bed.

"Okay. Kara why don't you stand on the other side of the bed with Eliza." Lena suggests.

Kara nods slowly and moves over to where Lena suggested, as she does Eliza grabs hold of her adopted daughter's hand and holds it tight. Kara just looks at Eliza and gulps with worry. Alex then approaches Lena, holding the syringe behind her back, out of site of Alura.

"Okay darling. This is going to hurt, but it will be much quicker than the spinal taps. I'm sorry though. I promise I'm not trying to hurt you." Lena says with so much care in her voice.

Alura nods slowly at Lena.

"Okay..." Alura says, softly.

"Honey, grab onto my hand and close your eyes. I don't want you to see this." Kara says as she holds out her hand

Alura grabs Kara's hand and Lena carefully pulls down Alura's gown to expose her chest. Alura looks at Lena then Alex before finally landing on Kara and Eliza. Kara gives her daughter a reassuring nod with a smile and Alura then closes her eyes.

"Okay. I'll tell you when it's over." Lena says softly to the half Kryptonian.

Alex hands Lena the syringe. Lena takes a deep breath and then penetrates the skin and enters the heart and begins drawing blood. Alura just let out a small gasp in response, holding Kara's hand tight. It only takes Lena a few seconds to draw all the blood she needs and she then carefully removes the syringe and hands it to Alex. Alex hands Lena a cotton swap and a plaster to cover up the puncture wound.

"All done. You were so brave Alura." Lena says.

Alura opens her eyes again and the first person she looks at is Lena. Alura gives Lena a small smile. In response Lena kisses Alura on the forehead before she moves away.

"Okay. I'll be right back. Let me just analyse the blood." Lena says.

"I'll come with you." Alex replies.

Lena gives Alex and nod and the two quickly leave the room. Alex and Lena enter the other medical bay and Alex immediately begins to set up the analysis, making sure to not use all of the blood. They don't want to have to do that again to retrieve another clean sample of Alura's blood. Alex and Lena then carefully examine the blood and Lena's theory is proven to be correct. Alura does have two blood types which make up her own blood type. Although this isn't the inherent issue with Alura. The issue is that it is clear that within the human blood type there is an inherent genetic flaw, one that Alura obviously has got from her father, whomever he was.
