Barry and Iris reunite, the Earth-38 gang regroups, Sara has something to say, Jax and Stein are witnesses to the hilarious meeting of Mick and Leo, and Caitlin has news.

Enjoy!

Barry walked onto the bridge and sped up when he saw Iris waiting for him. "Are you OK?" he asked.

Iris sighed, hugging him tightly. "I can't even begin to answer that right now." Barry chuckled, and Iris giggled slightly. "We should be on our honeymoon."

"We should be on a beach, drinking mai tais out of coconuts," Barry agreed, grinning.

Iris laughed. "Instead, we're on this spaceship, looking for our friends' evil doppelgängers."

"We should have just eloped," Barry decided.

Iris laughed, hugging him again. "Yeah."

"So the whole reason these Nazis are invading was just to get Kara's heart?" Clark asked.

"And to conquer this Earth," Lena nodded, rubbing the back of her neck.

"But Oliver in the High Castle seemed to put his Kara first, so," Winn shrugged. "Yeah." He swallowed hard. "It's just . . . to see both of them as Nazis, and when both Olivers were aiming at their different Karas . . . " He dropped his head into his hands. "I'm glad I'm not going to be in the field facing them."

"Not only that, but Nazi versions of Malcolm and Slade?" Lena shook her head. "If they're what our Malcolm and Slade used to be like, I definitely understand why Sara reacted how she did."

"But why does Nazi Kara even need our Kara's heart?" J'onn frowned.

A sigh came from the entryway, and everyone turned to see Alex walk in, looking exhausted. "It's a . . . long story," she said, smiling faintly when Lena hugged her. "It's a long, brutal, sad story. It's basically how Oliver and Kara got together, except with Nazis, a psychopathic Laurel who betrayed the Reich making Black Arrow kill her in a completely horrifying way, and a serum made by Nazi Barry – or Blitzkrieg – that destabilized Overgirl's cells to the point too much solar radiation started to kill her."

" . . . what?" James shook his head. "Sorry, can you repeat that again? Slower this time?"

Alex sighed, sitting down by J'onn, rubbing her forehead. "It's awful."

"We've got time," J'onn put a hand on her shoulder.

Alex took a deep breath, then started from the beginning.

Sara walked into the medbay slowly, taking a look at Kara's readings. She looked like she was close to being healed, and she walked over, squeezing her hand lightly. "Oliver needs you, Kara," she whispered. "Wake up soon."

Maybe it was her imagination, but she swore she felt a light squeeze in response, but a look over Kara revealed she was still out. Sara released her hand, then walked over to Malcolm's bed. She looked long and hard at him before looking at his scans. A small smile formed when she saw Malcolm was almost completely healed, and she turned back. "Who would have ever thought we'd be here?" she asked out loud, shaking her head. "You know, if this was before everything that just happened these last few days, I would probably slit your throat." She swallowed hard. "And now I can't think of doing that after that stunt you pulled."

She sighed, leaning against the wall. "I hated you. I hated you so much for sinking the Gambit, for the Undertaking, for being behind my death, for putting Thea through so much pain, for everything you did with Thawne and Darhk." She made a helpless gesture, letting her arms fall to her sides. "And all you've done since the wedding is fight to make sure they don't get this world, and make sure all of us returned." She chuckled. "And to top it all off, you took a bullet for a man you would have killed before." She shook her head. "I'm never going to understand you," she looked at Malcolm. "I never will. Just when I think I know you, you just keep surprising me. But this is one surprise I'd rather know you for."

She straightened and put her hand on Malcolm's shoulder. "Thank you," she said sincerely, biting her lip. "Thank you for looking out for my team."

She squeezed lightly before brushing her hair out of her face, turning and leaving. "They're nearly there," she told Caitlin, who passed her by to check in.

Caitlin nodded and headed on in as Sara headed back to the bridge.

"Man, we've seen some crazy stuff in history, but a Nazi Earth takes the cake," Jax sighed as he and Stein entered the kitchen.

"I agree, Jefferson," Stein nodded as both of them opted for water. He looked down into his glass, then sighed. "We shouldn't have separated."

"Hey, we were in the middle of a firefight, we did what we had to do," Jax shook his head.

"But Malcolm and Thea were not that far away from us, as evident when they ran to our aid," Stein argued. "And if they hadn't come, I would be in the medbay instead of Malcolm, possibly dead."

"Don't say that, Grey!" Jax stared at him.

"But you know it's the truth, Jefferson," Stein swallowed. "If Malcolm hadn't taken that shot for me, I would be dying, or dead. And it was because I told you we should separate. Maybe if we hadn't, he wouldn't be in this situation."

"If we hadn't and called them to help, then maybe the shot would have killed one of them, or both, instead," Jax pointed out. "Grey, everything about that battle was already not in our favor. We were outnumbered, some of them didn't have their everyday weapons, and we were in a huge space where we split up almost instantly. I think Malcolm getting shot and no one else getting hurt was the best-case scenario." He paused, glass nearly to his lips. "No offense to him."

Stein chuckled. "I'm sure he would agree with you, Jefferson."

"My point is, we got lucky," Jax said, and he took a deep breath. "And if that had happened to you, Grey . . . I don't know what I would have done."

"Every time we go out into the field together, we run the risk of falling," Stein put a hand on his shoulder. "I never want that to happen to you, Jefferson."

"And I don't want that to happen to you, either, Grey," Jax shook his head. "You deserve better than that." He swallowed. "Which is why you deserve to retire, go back to Clarissa and Lily and Ronnie." He looked back up at Stein, whose eyes were wide. "When we get back, we'll take the cure."

"Are you certain, Jefferson?" Stein asked.

"Man, I've never been more sure," Jax nodded. "It's like you said. If Malcolm hadn't taken the shot, it would be you in the medbay." He closed his eyes. "And for all I know, I would be taking a trip to Clarissa and Lily that you were killed by Nazis. I mean it. It'll keep you safe."

"Then when we return from this fight," Stein nodded. "I, for one, am determined to send them back where they came from."

Jax smiled. "One last time?"

Stein smiled back. "One last time."

They chuckled, heading for the dining area, where they found Mick drinking. "Even when Nazis invade," Jax couldn't help but shake his head.

"Well, at least it doesn't change," Stein chuckled fondly.

"How's Skirt?" Mick looked up at them.

"Kara?" Jax raised an eyebrow.

"Well, I don't mean Nazi Skirt."

Jax and Stein exchanged amused looks. "Overgirl doesn't even have a skirt."

"Well, I'm not going to call her Pants."

"Oh, God," Stein rolled his eyes.

"I'm sure she'll be fine," Jax hid a grin. "Good to know you're worried about her."

"I'm not worried," Mick sniffed. "She's a tough bitch."

"Don't let her sister hear you call her that," Stein muttered into his glass, making Jax snort.

Mick reached for another beer bottle when Leo walked in, raised an eyebrow, then walked over. Mick balked in shock, and Leo reached out, taking the beer bottle away. "Hey there, friend," he said. Mick stared in shock, Jax and Stein watching in growing amusement as Leo sat down across from Mick. "No need to numb your feelings with alcohol."

Jax snorted again, this time much louder. Mick just groaned, smacking himself repeatedly in the forehead. "The ghost is back."

"He's not a ghost, Mr. Rory," Stein couldn't help but chuckle. "He is quite real."

"I'm Leo," Leo nodded. "Leo Snart from Earth-X." Mick stared blankly, making Jax hide a growing grin behind his hand. "It's OK, buddy. I know you're hurting over Supergirl."

Mick just groaned and reached for another beer bottle. Leo reached out to stop him, but Mick growled. "Get yoru hand off me."

"What is wrong, partner?" Leo tilted his head. "Talk to me."

"You're not my partner," Mick scowled. "You're a gangbanger."

Stein choked on his drink at that, making Jax burst out laughing. "Doppelgänger," Stein coughed as Jax clapped him on the back. "You mean doppelgänger, Mr. Rory."

"Whatever."

"Professor Stein is correct," Leo smirked. "And there was one of you on my Earth, too."

"Wait, was?" Jax blinked.

"Yes," Leo nodded. "Rest his soul."

"Wait," Mick blinked. "I'm dead on Planet Nazi?"

"Let me guess," Stein said dryly. "In a fire?"

Leo nodded. "You just kept going back into that burning police station until the last officer had been rescued."

All three Legends stared at Leo in shock at that statement. "I died trying to save pigs?" Mick asked in disbelief.

"Mick did?" Jax asked for clarification.

When Leo nodded, Jax and Stein exchanged wide grins of amusement as Mick groaned, putting his beer down. "I'm gonna be sick."

"Ohhhhh man," Curtis grinned widely as he looked around the Waverider. "I have just died and went to geek heaven!"

"Told you we picked the right guy," Zari smirked.

"Uh," Curtis blinked, following Zari and Amaya as they walked down the hall. "Picked the right guy to do what?"

"Hunt Nazis," Amaya answered as they walked into the laboratory. "Meet our resident Earth-X expert, the Ray."

Terrill smiled as Curtis walked in. "Well, uh, you can use my real name, Ray Terrill."

Curtis blinked as he shook his hand. "Your secret identity is your first name with the word 'the' in front of it?"

"Yeah," Terrill nodded. "Why? What's your secret identity?"

"Mr. Terrific."

"Really?" Terrill chuckled. "That's a little boast-y, don't you think?"

"Nah, it's just one of my favorite wrestlers," Curtis shook his head. "Still, that's – you should change your name. Can we talk about these Nazis?"

"They vanished," Amaya answered. "Owing to the fact that they have their own Waverider."

"A Nazi Waverider?" Curtis asked in surprise.

"Yeah," Zari confirmed. "We had been tracking them using the radiation signature given off by Overgirl because of her – "

"Extreme exposure to the solar radiation," Curtis looked past her, walking over to the computer, watching the screen in shock. "Are these readings right?"

"Yeah, of course they're right," Zari walked over. "Why?"

"Well, because the trace radiation readings on here are slowly approaching the Chandrasekhar Limit," Curtis answered.

Zari blanched, making Amaya frown. "Which means?"

"Overgirl isn't just dying," Zari swallowed, watching the screen light up red.

"Yeah, if she doesn't get Supergirl's heart, she'll create a supernova that will destroy the entire Midwest," Curtis nodded.

Oliver was restlessly pacing the library while Thea absently chewed on her nails when Caitlin walked in, brushing her hair behind her ear. "Hey," she said quietly.

"Are they OK?" Oliver asked, Thea looking up.

"I just checked," Caitlin nodded. "Malcolm's completely healed, Kara's nearly there. They should be waking up any time now."

Thea dropped her head into her hands in relief. "Thank you," Oliver whispered.

"Yeah," Caitlin nodded, leaving again.

As soon as the door closed behind her, Oliver let out a long sigh, pinching the bridge of his nose. "Thank God," Thea whispered.

"You read my mind," Oliver walked over to her, sitting beside her on the table. "This . . . " He chuckled bitterly, shaking his head. "Do you have any idea how much I want to kill my doppelgänger now?"

"As much as I want to kill every Nazi for what they did to my dad?" Thea smiled slightly.

"More," Oliver said coldly, making Thea turn to him. "You know Kara is scared of medbays after everything she's gone through with Cadmus, but you never saw where they were holding her. You didn't see the condition she was in when Slade, Malcolm, Laurel, and I rescued her. They used Kryptonite on her, which is the only thing that can hurt her while she has her powers. Here, they weakened her completely with red sunlight, to the point anything could hurt her. When Slade's doppelgänger shot her and I saw Thawne's scalpel in her . . . " He closed his eyes, swallowing hard. "I thought it was horrible when she was stabbed in CatCo and when Lillian used Kryptonite lights on her and Clark. This . . . every time I close my eyes, I see her bleeding out on all of us." He felt Thea take his hand and opened his eyes, turning to her. "I can't lose her," he told his sister, his voice cracking. "I just can't."

Thea nodded in understanding, pulling Oliver to her, hugging him tightly. "I know, Ollie," she whispered, feeling him hug her back tightly. "I know."

I promise, everyone's favorite female Kryptonian and dark archer will wake up next chapter. They've got to fight their doppelgängers, after all.
