Oliver was expecting something way worse, he had to admit. Not that helping a super being save the multiverse wasn't a big thing, but still. He knew it wouldn't be easy, but he was kind of hoping he would have to give his life to save his friends, kill someone or something like that. You never know what to expect with the crazy world he lived in, he thought as they traveled. He also couldn't help but worry. Worry because he had to leave everyone behind, everyone including her.

- I know why you worry... - Monitor commented as they walked.

- I figured you would know... You know everything, right?

- Yes.

- Then I think I deserve to know the whole story, your story... You know? Since I'm leaving everything behind and sacrificing myself here... It's only fair.

- She will be ok.

Oliver looked at him caught by surprise. This is not what he meant. He wanted to understand it all, to know why he was doing whatever he was doing.

- I can't tell you everything, but you know she can handle herself... We made a deal, after all... She will be just fine.

- This is not...

- I know.

Oliver stared at the ground as they walked. He wondered where the hell were they going while he remembered what made him lose sleep at night.

FLASHBACK

He had enough.

He couldn't let his sister destroy his beloved city, the people he loved. He fought so hard not to kill anymore, not to be dark, but he was beginning to feel he would have no choice. He tried everything, nothing worked. They stared at each other, he could feel the hate in her eyes and he felt sadness. He understood her, but he really hoped they could get closer, be a family. He knew now this was a foolish dream and they would never be a family.

- I will end you!

- You don't need to...

- I want to! – She stared deadly at him as she attacked.

It looked like they were performing a perfect dance, but deadly. Emiko attacked with all strength she had, hitting Oliver anywhere she could. Oliver avoided being hit a few times, but couldn't escape the punch on his chin. He took a few steps backwards and then two forward, blocking her attacks and hitting her at the same time.

And then it happened.

An arrow hit Emiko from behind, crossing her stomach, making her look scared at Oliver as she tried to stop the blood coming out from the deep wound. Oliver looked around, trying to figure out where the arrow came from. Emiko held his hand as she dropped on her knees. Oliver held her hand with his, staring into her eyes.

- Your friend... She's in danger...

- What? – Oliver looked confused at her.

- Kara... The alien.

Oliver looked shocked at her. Hoe the hell did she know that Kara was an alien? He was beyond worried about it now.

- I found out her weakness... And... I told the Longbow Hunters. They have means to hurt her, to hurt you. She needs to go away.

Oliver let Emiko's hand go but still looked at her. A mix of disappointment, betrayal, shock, fear and sadness took over him. Once again she put someone dear to him in danger, he knew she was beyond redemption, but he still couldn't give up on her. If she was telling this now, maybe she regretted everything? Maybe she wanted to do the right thing? Or maybe it was all just because she was dying.

- I forgive you. – Oliver told her as one single tear came down from his eyes.

- But... Oliver...

Emiko took a deep breath, tying to say something to Oliver. He held her once more.

- I just... Wanted a family...

Emiko closed her eyes and Oliver knew she was gone. He was still shocked but knew he needed to act fast. He grabbed his phone and dialed.

- Hello? Barry, please put Kara on? I know she's there... She told me earlier she was going to help you. Ok...

He waited for a few seconds, seconds that felt like eternity.

- Kara? Listen, they know... Yes, she found out about you and told them, they found a way to hurt you. It's not safe... Please, I know you can handle yourself, but please. If they found a way to hurt you, they will try, believe me. And... I can't... I can't let that happen.

Oliver felt a whoosh of air behind him and turned around. Kara Danvers was staring at him, with a determined look.

- I won't hide!

- I'm not asking you to... I just hope you listen to me and stay in your Earth while we deal with this threat. Please, Kara.

- I...

- They just killed her. They killed my sister. She was their leader and they killed her because she told me they know. Please, listen to me.

Kara stared for a few moments at him and looked down, defeated. She took a deep breath, knowing she wouldn't have a say on this because it was Oliver's world and he knew it better than anyone.

- I'm your friend; I can't let anyone happen to you in my world. – Oliver said as he took one step closer to her.

- Ok... You won. – She said – But... I need to do something before I leave...

Oliver nodded with his head, wondering what it was until he felt Kara centimeters apart from him. She walked determined towards him, grabbed him by the collar of his suit and her lips took over his in a sweet and passionate kiss. He kissed her back because he felt he needed to, he couldn't explain. He felt fire and ice all mixed up inside of him, it was something he wasn't expecting, but he knew now he needed it badly.

And then she was gone.

He opened his eyes and touched his lips with his finger. He took a deep breath and closed his eyes.

This wasn't going to disappear from his mind anytime soon.

END OF FLASHBACK

Monitor looked at Oliver's face, knowing he was a mess inside. He couldn't blame him, he understood. He couldn't do a thing about it, but he understood.

- I was born in OA's moon in the beginning of time. OA is a planet in the center of the universe.

- Beginning of time? This is a long time ago... - Oliver said glad the guy was finally telling him something.

- Yes, it is. I used to catalogue all the realities of the multiverse. Until the antimatter universe was created by a curious Maltusian scientist named Krona that decided that it was a good idea to do a forbidden experiment just to see the origin of the universe. There are certain things that are not meant to be known...

- I guess not only humans like to destroy the world over their curiosity.

- Believe me; a lot of being in the vast universe is like that. Thanks to his experiment, it disrupted a cosmic reaction, resulting in an opposite universe of pure evil. All its inhabitants glorify evil, and one of them is my evil counterpart, the Anti-Monitor.

- There's an evil version... Of you? – Oliver looked like he really had enough of all of this.

- Yes.

- And I thought evil Kara was bad...

- He corrupted many planets; waves of antimatter destroyed a lot of Earths. I sensed he was going to do the same with all other Earths; his goal is to destroy the whole positive matter universe, the one you live in. That's why I started recruiting heroes from all universes, this is the only way to stop him and save the multiverse.

- Thank you for telling me... I just... Need some time to process it all.

- I know. You're a down to Earth person, someone used to fight with your hands and weapons, used to deal with thugs, gangs, dangerous criminals and it all changed when you met your friend Barry and your... friend Kara.

Oliver just stood in silence for a few seconds, still thinking about everything he heard from the Monitor. It was a lot to take in, he thought.

- I'm still a bit confused about where we are going...

- Like I said, we're making a few stops in this universe. And then you'll know more.
