Sitting in the kitchen of the Waverider, was Mick, getting drunk on multiple bottles of beer, when suddenly a bottle was taken from him. By someone he once knew. He stared up to see Leo Snart. "Hey there, friend." But all Mick did, was internally freak out. "No need to numb your feelings with alcohol."
He sat down in front of Mick, as Mick started softly hitting his forehead. "The ghost is back."
"No, not a ghost," Leo said and Mick looked at him. "I'm Leo. Leo Snart from Earth-X. It's okay, buddy. I know you're hurting over Firestorm."
Mick scoffed before he grabbed another bottle, but Leo tried to stop him. "Get your hand off me."
"What is wrong, partner?" Leo asked. "Talk to me."
"You're not my partner. You're a gangbanger," Mick said, taking another sip of beer.
"I think you mean doppelgänger. And there was one of you on my Earth, too. Rest his soul," Leo said and Mick looked at him.
"Wait. I'm dead on Planet Nazi? Let me guess. In a fire?" Mick asked.
"You just kept going back into that burning police station until the last officer had been rescued," Leo sadly said but Mick looked at him annoyed.
"I died trying to save pigs?" He asked. "I'm gonna be sick."

In the med bay, Caitlin turned to Jax, who looked worse then before. "How you feeling, Jax?"
"Oh, don't worry about me. How's Grey?" Jax asked.
"I have him sedated. Don't worry. Gideon and I are doing everything we can to fix him," Caitlin assured.
"Okay. Good," Jax muttered.
Caitlin smiled until she walked out of the med bay, her smile dropping, now just concern on her. She walked down the halls where she was met with Ray Palmer. "Still no improvement?"
"He's getting worse," Caitlin said.
"Marty or Jax?" Ray asked.
"Both," Caitlin answered.
"I just can't believe there's nothing Gideon can do," Ray said.
"Medically speaking, Professor Stein shouldn't even be alive right now. The only thing that kept him from dying is-"
"Jax. Bonding with him," Ray said.
"Yeah. Jax is basically functioning as a human life-support machine, able to keep the Professor alive but...only for so long," Caitlin said.
"Does Jax know?" Ray asked.
"That he's gonna die too?" Caitlin asked. "I didn't know how to tell him."
"It'll be okay. We got a whole mess of smart people on this ship. Somebody's gonna figure out something," Ray said and Caitlin nodded before he walked off.

Walking through the halls, Curtis was freaking out with Zari and Amaya with him. "Oh, man, I have just died and went to geek heaven."
"Told you we picked the right guy," Zari told Amaya.
"Uh, picked the right guy to do what?" Curtis asked.
"Hunt Nazis," Amaya said before they turned into a large room, with loads of tech in it.
"Meet our resident Earth-X expert, The Ray," Zari said, gesturing to The Ray standing inside the room, without his helmet on.
"Well, uh, you can use my real name, Ray Terrill," he said as he and Curtis shook hands.
"Your secret identity is your first name with the word the in front of it?" Curtis asked.
"Yeah. Why? What's your secret identity?" Ray asked.
"Mr. Terrific," Curtis said, causing Ray to laugh a little.
"Really? That's a little boast-y, don't you think?" He asked.
"Nah, it's just one of my favorite wrestlers. Still...that's...you should change your name," Curtis said before looking at Zari and Amaya. "Can we talk about these Nazis?"
"They vanished. Owing to the fact that they have their own Waverider," Amaya said and Curtis stared at her taken back.
"A Nazi Waverider?" He asked.
"Yeah, we had been tracking them using the radiation signature given off by Overgirl-" Zari started but Curtis saw some readings from behind her.
"Because of her extreme exposure to the solar radiation," Curtis said, walking up to the computer. "Are these readings right?"
"Yeah, of course they're right. Why?" Zari asked as they all followed Curtis.
"Well because the trace radiation readings on here are slowly approaching the Chandrasekhar Limit," Curtis explained.
"Which means?" Amaya asked.
"Overgirl isn't just dying," Zari realized.
"Yeah, if she doesn't get Supergirl's heart, she'll create a supernova that will destroy...the entire Midwest," Curtis said.

Back in the med bay, Jax was barely hanging on, when he heard a weak and quiet voice call out to him. "Jef...Jefferson? Jefferson," Jax turned to Professor Stein, who was awake now. "I need...I need to tell you something."
Jax pulled himself out from the chair he was in, and headed over to Professor Stein, hovering over him. "Well, talk fast. Because unless you're sedated, Gideon can't do her thing, patch you back up."
"Can't you see that I'm dying?" Professor Stein asked.
"What...What are you talking about, man?" Jax asked.
"I'm old, Jefferson. And even if I hadn't been shot, no one lives forever," Professor Stein said.
"Grey, I don't even want to hear you talking like that, man," Jax said.
"As long as we're connected, I'm nothing more than an an anchor around your neck. Which is why you must help me," Professor Stein said.
"I don't understand. I-" But Professor Stein pointed at something besides them. Jax looked to see it was the drug Cisco made to separate them. "Not Cisco's drug."
"Gideon resynthesized the liquid. She assures me it will free you from my body's biology. And it will free you of mine," Professor Stein said.
"I'm the only thing that's keeping you alive, man. You're asking me to kill you, Grey," Jax said.
"I'm asking you to let me die so that you may live. Please hand me the vial," Professor Stein pleaded.
"No," Jax said.
"I know...I know you think you're strong enough for both of us. But unless I do this, we'll both die," Professor Stein said.
"Then we'll both die. I don't-"
"No," Professor Stein said, his voice cracking and tears watering up in his eyes. "You have your whole life ahead of you."
"Grey-"
"But now it's time for you to let me go."
"No, I'm not ready for you to go," Jax said, his voice cracking up as well.
"I'm not either. But when you think about it, compared to the Cosmos, one's life is but a blink of an eye," Professor Stein said, causing Jax to laugh.
"Really? You're gonna lecture me about astrophysics right now?" Jax asked. "Grey, please don't do this to me. I can't do this."
"You once told me...that I was like your father and I said you were my son. How could a father do anything less?" Professor Stein asked and Jax began to cry even more.
He walked around to the other side of Professor Stein, and picked up the vial. He sighed heavily before handing the vial to Professor Stein, though his entire body was shaking in fear. "Thank you, Jefferson."
He then opened the vial and gulped it down, and Jax was sobbing even more. "Grey, no, don't."
"Stay with me, please. I'd rather not to be alone." Jax nodded before taking his hand. "Please...tell Clarissa and Lily that I love them."
"I promise," Jax swore.
"Thank you, Jefferson...for the adventure of a lifetime. I hope your life is long and full of love...Just as mine...as been," Professor Stein's last words were.
Jax bursted into tears and pleading once Professor Stein passed, crying into his head body, calling out for him. But he never called back.
"Jax."
Jax looked at the entrance of the med bay to see Sara standing there, confused as to what as going on, but deep down she knew he was gone. "He did it for me."
Learning the news of Professor Stein's death took a toll on everyone, in different ways. Kara walked into the library where Barry was, but by the saddened look in her eyes, he knew.
Caitlin and Cisco stood in the bridge together, staring out into the sky, whilst Professor Stein's glasses were nearby.
Ray Palmer stared at a photo of him and Professor Stein when they were in the Wild West, while he sat down in the tech room. And Amaya placed a comforting hand on his shoulder. He looked at her, but also at Zari and Nate, who sat nearby. "Where's Jax?"
Stein Household
Jax nervously walked up to the home where Clarissa and Lily were, knowing he had to do what he had to do. He softly knocked at the door, and Clarissa came running.
"I'll get it, honey."
When she opened the door, she smiled seeing Jax, "Jefferson-"
But immediately, she knew something was off. He looked at her almost guilty. "I'm sorry." A harsh and painful realization slowly expressed onto Clarissa. Her husband was dead.
"Oh, no," she dropped to her knees but Jax caught her. She started sobbing hard in his arms, and he cried as well.
But then he looked up to see Lily was heading their way, realizing what happened to her dad. "No." She dropped to her knees as well, crying while Jax held them both tightly, and they all cried together.
Waverider
Sara walked into the hallway but stopped when she found Oliver standing there, waiting for her. "How are you holding up?"
"I'll cry at the funeral," Sara said before she tried to walk away but Oliver stopped her.
"Sara," he sternly said.
"I'm fine," she muttered, then the two began to walk off together.
"We need to gather everyone. Overgirl's gonna go nuclear, and the Earth-Xers are gonna use their Waverider to threaten Central City and leverage us into surrendering Kara," Oliver explained.
"How do you know that?" Sara asked.
"It's exactly what I would do," Oliver said.
———
Zari walked with Amaya down the hallway, into the bridge when Amaya noticed Zari was wearing her superhero outfit. "Nice outfit."
"Yeah, I didn't want to feel left out," Zari said before they walked onto the bridge, where everyone was.
"Where are we with locating the other Waverider?" Green Arrow asked Mr. Terrific and The Ray.
"We got a pretty good idea," Mr. Terrific said as Zari and Amaya joined them. "I mean, we've all heard of the Chandrasekhar Limit, I assume?"
"The data indicates it's still in the vicinity of Central City," Zari told the Green Arrow.
"Which also indicates that Overgirl isn't long for this world," The Ray said.
"Which means that this world isn't long for this world," Mr. Terrific said.
"Failure's not an option," Green Arrow said and they looked at him. "Losing is not an option. We are gonna win. And we are gonna show these people that this Earth — belongs to us."
"Great speech," Killer Frost said, who was nearby listening in.
"Sorry to interrupt, Mr. Queen, but we're being hailed by a fellow Timeship."
"Put it on," Green Arrow sternly said.
———
Soon enough, a holographic image popped up on the console in the middle of the room, of Oliver Queen of Earth-X, but all he saw was our heroes stacked up in rows, facing him.
Front row: White Canary, Green Arrow, Felicity Smoak
Second row: Steel, Killer Frost, Supergirl, SF, Spider-Man, The Flash, Zari, Vixen
Third row: Alex Danvers, Wild Dog, Iris West, Mon-El, Black Canary
Fourth row: Citizen Cold, The Ray, Heatwave
Fifth row: Mr. Terrific, The Atom, Harry Wells, Vibe
"What do you want?" Sara sternly said to the hologram.
"To offer a truce."
"In exchange for what?" Flash asked.
"We will return to our Earth peacefully if you meet my one demand. Supergirl comes with us."
The Green Arrow looked back at Supergirl for a moment, to see she looked almost scared to be back in the grips of the Earth-Xers. The Green Arrow shook his head before looking back at the hologram. "Here's another difference between you and me," he said as he walked up to the console. "I don't abandon my friends."
He then slammed his fist on a button, which turned the call off, before looking back at everyone else. "All right," Sara said as she also faced everyone. "Everybody ready to go?"
"Never been more," Nate said.
"We can't bring Marty back back, but we can protect the city he loved," The Atom started, and The Flash looked at Supergirl, just to see she was already looking at him. "And the family he left behind."
"For the Professor," Sara said, and they all had a knowing look on each of their faces. Revenge. "Now let's go kick some ass."
Streets of Central City
The Earth-Xers were rampaging all throughout the city, killing everyone who got in their way, not caring about anyone or anything. But as they did, suddenly, Dark Arrow noticed something.
Walking towards them in a huge long row, was our heroes, ready to fight, with Supergirl, SF, The Ray and Killer Frost in the air.
"Kill them all!"
"Yes, sir!"
Immediately, the heroes and the Nazis collided, fighting each other. Sara used her assassin skills. Steel his metal strength. Black Canary her vibrational scream and fists. Supergirl and SF their laser heat vision. Vixen her spiritual powers. Zari her totem. Citizen Cold his gun. Flash his super speed. Green Arrow his arrows. Spider-Man his super strength. Mon-El his leaping and strength. Mick his heat gun.
Speaking of Mick, he used his gun to blast down a Nazis, with no reaction at all, causing Citizen Cold to run up to him. "Excuse me! You can't just go around roasting people."
"Why not?" Mick asked.
"You ever heard of due process? Rule of law?" Citizen Cold asked.
"No," Mick said before walking away.
As Sara and Alex together fought off Nazis, Sara saw that the Wellenreiter was shooting down at innocent people, who were trying to escape with their life. "Could use a little help here."
"I got you covered."
Suddenly the Waverider zoomed at the Wellenreiter, shooting at it, trying to get it away from the civilians. Which worked, and the Waverider now chased after the Wellenreiter.
Waverider
At the bridge, Cisco sat at the controls, geeking out while Harry stood by him. "Whoa!" He chuckled while Harry looked annoyed. "This is just like Star Raiders on Atari except it's real!"
"Cut the chatter, Red 2. Fly the ship," Harry said.
"Launching torpedo one," Cisco said, while pressing a button.
"You don't have to say it out loud," Harry muttered.
But when the torpedo hit the Wellenreiter, it seemed like it just burst into dust, and Iris, who was nearby at the console of the bridge, noticed this. "Okay, guys, is it just me or is this not working?"
"It's not working."
"It's not working."
"You need to take down their shields."
But just after a few moments, the three assuming Felicity was trying to hack her way in, she spoke again.
"Guys, this isn't working. I think we need a bigger gun."
Suddenly, they saw Supergirl zoom past them, heading right for the Wellenreiter. "Way ahead of you."
Wellenreiter
Overgirl was standing at her controls, glaring what was in front of her, the destruction of everything satisfying her, but it was ruined when her officer walked up to her. "General," she looked at him. "We've got inbound."
"Then fire counter-measure," she ordered.
"We can't. It's hovering directly off our bow," he told her.
"General," Overgirl looked to the windows again to find Supergirl floating in front of it, crossing her arms, smirk on her face. "Would you care to step outside?"
Angrily, Overgirl pressed the side of her face, which activated her face helmet, then she zoomed out of the ship, grabbing Supergirl on her way out.
Waverider
Seeing Supergirl get flown off by Overgirl, Cisco nervously chuckled, not sure what to do next. "Waiting for some good news here."
"I don't have any for you, man. The only way to take out their shields is to get someone onboard that ship."
"We're on our way."
Confused, Cisco, Iris and Harry looked to see Killer Frost, icing a path up from the ground to the Wellenreiter, with Zari and Vixen.
Wellenreiter
Killer Frost, Zari and Vixen landed on the bridge together, where they were met by lots of Nazis. Killer Frost froze some of them, Zari used her air totem on some of them, and Vixen fought them down with some old fashioned fist fighting. "We're on the bridge, Felicity."
"And we don't know what we're looking for," Vixen said as the two of them went to the console.
"Yeah, yeah, yeah, I'm working on it."
"Felicity's got it. I'm sending you the source code for their deflector shields."
"Yeah, got it. Manual override protocol," Zari said.
"If I am reading this correctly, all you need to do now is—"
Killer Frost looked back at a red button nearby, that was blinking. "Hit the big, blinking red button."
Waverider
Iris saw on her screens that the shields were down on the Wellenreiter, and she smiled, looking at Cisco and Harry. "Got it. Shields are down."
"Harry, you think you can handle this bad boy?" Cisco asked as he got up.
"Walk in the park, Kazansky," Harry said, taking his place.
Cisco walked around the chair, placing his goggles on, when he was met with Iris's confused look. "Where are you going?"
"Getting our friends off that ship," Cisco said before looking back at Harry. "Count of ten, hit them with everything we got."
"You got it," Harry said before Cisco opened up a breach and he jumped in.
