Suitable for ALL AUDIENCES.
Oliver grunted as he regained consciousness, he looked around to see Sara, Alex and Jax on his left while Kara, Barry and Professor Stein are on his right.
O-"Is Everyone alright?"
S-"We're gonna have to work on your definition of 'alright' Oliver."
"Yo, Grey, you good?" Jax shouted.
PS-"It seems my retirement was somewhat tardy."
Someone claps behind them and they all turn around to see Thawne stood above them.
"Well, here we are. This is fun. For me. Not so much for you."
He turns to look at Barry and leans towards him
"All the times you've killed me, and now here we are and all I have to do is kill you once."
"Enough, Eobard, Enough." Overgirl shouts as she walks towards them.
"Hey, you might want to listen to her. We know that if you wanted to kill us you wouldn't have put these dog collars on us first." Alex sneered at Thawne.
"Now I know what it feels like to hate myself." Kara comments.
"Well Done." Dark Arrow announces as he walks towards them, Overgirl turns to face him
"It wasn't a problem." Overgirl then starts to falter and collapses to the ground with Dark Arrow catching her by the arm.
OV-"The pain, the pain. I don't know how much longer I can bear it?"
DA-"It's alright, it's alright. You're gonna be alright because we found her. We found her and now we have her. I love you. Now, very soon, this nightmare will be over, and I will take you home, so stand."
Overgirl takes a deep breathe before they both stand up simultaneously before turning to look at their doppelgängers. Dark Arrow looks at Thawne as he walks towards them.
DA-"STAR Labs is secure."
B-"If you hurt my friends..."
DA-"I did hurt your friends, I really enjoyed hurting your friends."
O-"Are they alive?"
DA-"Yes, yes, for now. We need your Kara's cooperation. Well we don't need it. It would be preferable. But for the time being you are more valuable as leverage."
A-"What do you want my sister for?"
OV-"To save my life, that's your little mission statement isn't it? Help people, save lives, well now's your chance."
T-"The general is dying."
A-"Her blood, she's been exposed to too much solar radiation."
OV-"Yes, like Icarus I flew too close to the sun."
DA-"But we can save her. We're going to save her. All we need is a new heart. And, luckily, on this planet, we found the perfect donor."
A-"You stay the hell away from my sister!"
OV-"Mmm. Such loyalty. My sister tried to kill me."
B-"That's why you stole the prism? So you could duplicate a red sun, weaken Kara, and cut into her?"
OV-"Can't make an omelet with invulnerable eggs."
K-"Wait." Kara looks at her doppelgänger now that the shock has worn off and points at Thawne and Dark Arrow. "They don't know."
DA-"Know what?"
Overgirl looks to Dark Arrow before turning back to Kara with a somber look on her face.
O-"Kara what are you doing?"
K-"She's pregnant."
T-"Wait, what!"
DA-"How do you know that?" Dark Arrow turns to Kara taking a step towards her.
K-"When you revealed yourselves to us, I heard another heartbeat I didn't figure it out until you two said you were married."
Dark Arrow tuns to Overgirl. "Why didn't you tell me?"
OV-"Then you would have to make a choice us or the reich and we both swore an oath that the reich would come first."
DA-"We would have figured out a way to do both."
OV-"No we wouldn't have, no matter what happens you always need to choose the reich."
Before Dark Arrow could say anything else Kara spoke up, "I have an offer for you."
Everybody turns towards Kara,
B-"Kara..."
DA-"And what's that?"
K-"I go with you back to Earth-X to give you my heart to save your wife and child, on the condition that you leave this earth in peace."
S-"Kara, no."
OV-"What do you want in return?"
K-"24 hours to say goodbye to my family and friends."
OV-"Okay, you have 24 hours, meet us here in 24 hours."
Kara nods her head as everybody collars are deactivated, as the Nazis walk out of the warehouse Kara uses her heat vision to get out of her handcuffs while Barry destroys his before they free everybody else.
A-"Have you lost your mind?"
PS-"Miss Danvers, that was very brave."
K-"Lets just get back to STAR labs, then we can talk."
-Back at STAR Labs-
With Everbody now in the cortex, everybody in the warehouse can clearly tell that the others are tense, with them all staying near Kara.
I-What happened?"
B-"We were captured by the Nazis."
F-"And you are all unharmed?"'
O-"Yeah, because Kara made a deal with them."
CA-"You what?"
K-"Their Kara is dying, but she's also pregnant. I made a deal with them that I go with them back to Earth-X and give them my heart to save her and her child's life. And in return they will leave this planet in peace."
I-"Kara, why would you do that?"
K-"When my mother sent me to Earth it was to protect my cousin, however when I arrived he didn't need my protection. So I spent years fitting in before coming out as Supergirl and protecting the people of National City. But now I have the chance to save all of you by giving the Nazis what they want. And I know they are Nazis but I'm not going to let an unborn child die."
O-"Kara we would have fought them and we would have won, you didn't need to sacrifice yourself."
B-"Oliver's right, we won against the dominators, so how hard can Nazis be?"
A-"Kara please don't give up. Fight this."
K-"I'm not giving up Alex, I'm using my powers to save the world and if I die achieving that then I'm at peace with it."
A-"But what about National City and this Earth?"
K-"This earth has Oliver and Barry and My cousin Clark managed to protect Metropolis and National City before I came out as Supergirl he can do it again."
B-"Kara, please we are begging you don't do this."
S-"We beat Nazis before in World War Two we can do it again, we don't need you to sacrifice yourself."
K-"Actually you do."
Everybody looks at Kara with confusion.
O-"What do you mean?"
Kara took a deep breath and looked around the room.
What does Kara know?
