Kara felt something peaceful inside her; she had no idea where it came from. She actually couldn't tell where she was. Everything was really confusing. She could see her sister in front of her. She turned around and saw Oliver smiling at her. It was everything so bright, what was happening? She walked towards Oliver, feeling warmth inside of her as she never felt before, it was like it was revealing to her what she truly felt deep inside. She smiled at herself as she looked around and could see all her loved ones surrounding her, also smiling at her. It was a calming and peaceful feeling. She felt safe and loved.

But she wasn't safe.

She opened slowly her eyes, confused about everything. As her vision became less blurred, she could see a huge mess happening. People fighting everywhere, rays of light passing by her in super speed but she could see who it was: Wally, Barry and that freak Dark Flash. She looked to her side and saw Oliver stuck in an ugly fight with his evil twin. He had fury in his eyes and was determined to take Dark Oliver down at any cost. For a brief moment, it worried Kara. Worried about Oliver's thirst for justice and what it might do to him if he gave in his natural instincts of killing the guy. She had some hope it wouldn't come to that, but she worried. As she turned her face, she saw Overgirl floating above her.

- Wake up, sleeping beauty! I'm not done with you! – She laughed as she attacked Kara once again.

Kara was quick to roll over the floor and take flight in super speed, going in Overgirl's direction and punching her hard on the face.

Oliver was having a harder time than he thought he would, fighting Dark Arrow. He had the exact same abilities as him when it came to hand on hand combat. It was like he could anticipate all of his moves, blocking him every time. Oliver wasn't going to let him win like that, so he fought even harder. It was a bit scary, he confessed mentally to himself, because it was like Oliver was looking at the mirror in his darker days from the past. This is what he could have been... It was scary. Kick after kick, twirl after twirl, kneeling on the guts, hand blocking arms, Oliver never felt so exhausted in his life like he was feeling right now. Oliver took a few trick arrow and shot him, but he blocked with his own arrows, being a bit faster than Oliver and being able to shot him in the shoulder five times in a row. Oliver kneeled on the floor, feeling a hell of a pain but never gave up, still trying to hit Dark Oliver. He used his feet to make Dark Oliver trip as he was distracted trying to push the arrows deep into Oliver's flesh. Dark Oliver rolled on the floor as he fell, getting up again and kicking Oliver in the face. Oliver hit his head on the ground as he tried to ignore his pain. He took off the arrows one by one in an abrupt movement, holding back a scream of pain. He felt dizzy, he had no idea what those arrows had, and he wasn't sure if he could get up again. Dark Oliver prepared one more arrow to shoot him but Kara landed on the ground between them, her back to Dark Oliver.

Oliver looked at Kara standing between him and Dark Oliver. He was sure she was going to knock him down or something like that but she just kneeled in front of him, as she caressed his face.

- I'm not sure why, but I know this is important to you. Get up Oliver! I know you can do this! – She said as she stood up and reached her hand to him. – I have to go back to Overgirl; she is waking up from the ground. – She looked to her side and then back to Oliver – You wanted to take this horrible person down, and I know you can do it. Also... I trust you – She smiled with a knowing look as she ran fast towards a totally awake Overgirl.

Oliver took a deep breath as he looked at Dark Oliver again. He was just pointing the arrow towards him with an evil smile on his face. Oliver recognized that look because he had it once in him. That vicious look, that enjoyment as he tore bad guys down torturing them, as he killed his enemies in cold blood, when he dropped a lot of bodies when he came back to Star City. Everything was like a movie in his mind. He remembered how he felt alone when he came back, how he could trust no one and how he thought he was destined to be his own company for the rest of his life. All of bad dreams he had about his enemies coming back to haunt him and his loved ones, and how some of them came true. All things that made half his life a living hell, he could see reflected on that evil version of him. He looked Dark Oliver deep in his eyes as all the hell broke loose around him, and decided it was time to put an end on all of this. He felt like he needed to be the one to face his evil doppelganger, so he could put all darkness behind him for good. It was all enlightening now. Even having meeting Kara, and falling for her little by little as he was sure he was, all of that he could look in another perspective. So this was beyond personal, this was beyond important. This was crucial.

Oliver let his quiver and bow on the ground and ran viciously towards Dark Oliver. His attack was so fast, he literally took the arrow Dark Oliver shot at him with his hand and broke it in half, giving him a high kick on his chest, making the guy hit the wall. Oliver trapped him against the wall, giving punch after punch anywhere he could reach. He took him by the collar of his suit and threw him on the ground, hitting his nose repeatedly until he heard a cracking noise. His hand was all blooded now and he couldn't care less.

Constantine tried to use magic to contain some of the Nazis that tried to grab Ray and attack him, while Ray used his powers to throw some ray of lights to them, knocking them down.

Wally ran fast outside and came back in a matter of seconds while Barry was distracting Dark Flash, as he planned earlier with the scarlet speedster. He just hoped it all worked. Barry notice Wally's sign that everything was ok now and he lured Dark Flash outside.

Cisco and Caitlin were literally thrown behind a huge garbage can on the alley near the Nazi headquarters, by Wally, and they rolled on the ground.

- I need to remember to thank Wally for being so delicate about this! – Cisco said as he rested his back on the can, looking at Caitlin – Hey... Are you ok?

- I need her for this to work... - She said looking terrified at Cisco, but decided to be brave so she could help her friends. That was why she had come along after all.

Cisco looked frightened at Caitlin as she closed her eyes and took a deep breath, letting Killer Frost take over. Her hairs started to change to a light blonde, almost white. Her eyes turned an electric blue, her lips turned dark blue. Her whole face got paler and she looked up, smiling satisfied.

- It's great to be back! – She said with her cold voice. - I hope this doesn't take long; I hate the smell of trash...

- I'm sure it won't take long now... I hope so...

And it didn't. In a matter of seconds, two streaks of light appeared on the street. Barry stopped abruptly as Dark Flash stopped as well, looking at him in a maniac way. His back was to the trash can so he couldn't see Cisco approaching slowly behind him. Neither he could see Caitlin coming from behind the can, walking majestically towards him. She raised her hands and arched an eyebrow.

- Time to get frosty!

Since Barry was distracting him, Dark Flash was caught by surprise as he felt his whole body turning colder and colder. He couldn't move. He tried to phase through the ice but it was not working and he started feeling desperate. He couldn't even talk. Cisco took the speed force bazooka from behind his back and shot Dark Flash right in the chest.

- Say hi to them for me... If you can unfreeze yourself! – Barry said

The three of them watched Dark Flash disappearing into a bright white light and suddenly he was gone for good.

- Are you sure he won't escape? – Barry looked at Cisco full of worries in his eyes.

- Yes. I made sure of make a few changes in this beauty – Cisco gave a playful kiss on the weapon as he smiled at Barry – Let's just say he will have to find a permanent home there...forever!

Barry and Cisco high fived each other as they smiled with the first victory against the Nazis.

- One down! – Cisco said as he looked at Killer Frost. – And you? Are you going to help us?

- That's why I came for, right? – She smiled as they went back to the building.

Killer Frost entered the place frosting all Nazis she found along the way and throwing some sharp ice sticks at others. She was having the time of her life.

Oliver was still going with all his got against Dark Oliver. That situation for him was beyond personal and not just because it was his evil self, but because he saw everything he could have lived if he kept drowning in darkness. He had no mercy, never held back each punch he gave him, each kick, and each arrow that he drove into some part of Dark Oliver. His screams, his angry and desperate voice echoed Oliver's owns like a flashback, for every time he had suffered in the past, every loss he had. Oliver managed to kick Dark Oliver down to the ground and jumped above him, punching his face so quickly, Dark Oliver ended up passing out, his face all blooded. Oliver used one of his tricky arrows to involve him around strong wires, keeping him from moving in case he woke up suddenly. He felt exhausted. He felt a strong need of sleep, and a shower, but all of that could wait as this fight was far from over and Jackson was still in danger. He looked to his side just to see Kara still fighting Overgirl. It looked like a tie since they were both looking beaten up, tired, but determined to beat the crap out of each other. Kara's eyes found his, just after she used her heat vision on Overgirl's forehead again. Oliver nodded slightly with his head. It was time.

Thea, Dinah and Sara were pretty busy taking care of a few Nazi guards and Evil Sara. Sara fought against her twin evil like a warrior, but couldn't help but feeling weird all the time. It was the last thing she expected. Just as Oliver, she also had a glimpse of what could have happened to her if she was still deep in darkness as she was when she first joined the league. And it looked like this Sara also had her own league as she had the same techniques as her.

- I'm recognizing your fighting style... - Evil Sara said as she took Thea by surprise, by punching her arms and twirling, kicking her stomach. She looked back at Sara – League of Assassins...

- Former... - Sara said as she failed trying to stop Thea from getting hurt.

- I'm still on it!

- You talk too much! – Dinah said as she was fed up hearing that egocentric lunatic.

Thea got up and took a sword from behind her back, one she had brought with her to this Earth and wasn't expecting on using it. She was way better with swords than with arrows. She managed to scratch Evil Sara's face and right calf as Dinah gave them a look and took a step back, giving a huge scream, the loudest she had ever pulled off. Half guards dropped on the ground, their ears bleeding. Evil Sara tried to cover her ears but was she was thrown away with the blast from Dinah's cry. Her back hit the wall as she crashed to the ground. Sara attacked her when she was still down as Thea hit her with her blade, carving it on her shoulder.

Kara Danvers distracted Overgirl, by trying to grab her neck and hold her still, giving enough pressure for her evil copy to be pissed. Oliver approached Overgirl, but she managed to push Kara far from her, and turned around, grabbing Oliver's neck and bringing him high on the air.

- You will pay for what you did to my Oliver!

- OLIVER! – Kara shouted as she saw them high on the sky.

Kara wanted to help, but it was no use since Oliver had the kryptonite syringe in his pocket. She saw as he started to look dizzy around, managing to gather strength to take one of his hands inside the pocket of his pants. He took the syringe and jabbed it on her neck. They both fell to the ground, with Overgirl yelling in pain and the veins on her face turning green.

Alex and Cisco came running towards the evil alien on the ground as Alex grabbed her and Cisco prepared to open a breach.

- It's now or never, please take her to the DEO and lock her there! – Kara said as she looked desperate at Alex.

- Ok, ok... We will be right back – Alex said hugging Kara really quickly – Take care of everything here! – She looked at Oliver, Sara and Kara and grabbed Overgirl in her arms, not so happy about it, but doing it anyway.

Once the breach opened, Cisco and Alex, carrying Overgirl, stepped in and disappeared before Kara's eyes. She took a deep breath and looked at Oliver and Sara.

- They are going to be ok. Overgirl is captured, Dark Arrow is down... - Oliver said as he gave a weak smile at Kara.

- And Dark Flash is trapped on the speed force – Killer Frost came closer to them as she spoke.

- So it's just a few guards now...

- And Hitler himself! – Barry said out loud as he gave some Nazis a bowling effect with his super speed, taking a few down at once.

- The team is advancing towards the target... We need to take down just a few more guards so we can deal with the main problem with no more surprises – Sara said as she walked in the direction of a few other guards.

Kara and Oliver stood were they were, with Dark Oliver knocked down near them, still out. Oliver looked at him on the ground, taking deep breaths as he tried to recompose himself. The exhaustion was beyond real. Kara took a few steps closer to him and gently touched his hand with hers. She felt him tightening his hold in her hand as he kept looking down.

- Are you ok? - She looked worried at him as her fingers caressed his hand.

- Now I am... - He looked at her, giving her a knowing look as he smiled – Thank you.

Kara felt goose bumps on her stomach as she saw Oliver's smile. His fight with Dark Arrow must have been though for him, to deal with whatever he needed to by taking him down, so for him to be able to give her that genuine and sweet smile, it meant everything was ok. She also could feel his fingers against her hand and she couldn't wait for it all to be over. She could tell he needed to rest, and so did she, it was really overwhelming everything that was happening. She smiled back as she looked around, letting his hand go. Oliver followed her to the stairs as they went to the next floor and took down a few more guards. Half the team was on the top floor, fighting and exploring the rooms looking for Jax.

Nate tried to cover for Stein as they approached another room at the end of a dark corridor. He steeled up, taking a few guards down as Stein reached the door and entered it.

It was a scary room, with a really poor light. He looked at the corner of it and there was a huge iron cage. His heart jumped a little when he could see who was inside of it.

- Jackson! – He whispered as he saw his friend finally.

He needed to do something, he felt desperate to take Jackson from out of there, but there were a few shadows moving around it and Stein had no idea what to do. Fear took over him as he noticed who was that was coming out of the shadows.

- Grey, it's a trap! – Jackson said as a maniac laugh echoed the room.

- Hitler... Adolph Hitler – Stein said gasping in shock

- It's the great fuehrer to you!

Stein looked at Jackson that had a desperate look in his face. Stein couldn't even imagine what Jackson might have suffered in there, and an uncontrollable rage started taking over him little by little.
