The night fell with a chill in the air. Barry looked at his phone and pressed the hung up button feeling a bit confused. Sara looked curious at him.

- So...?

- Oliver called. He said Kara was acting weird and told him that the answer to what Doomsday is lies with our Kara and her team on Earth 38.

- Oh... Nice – Sara looked down her feet.

Barry felt his heart jump a bit while he thought crossed his mind. Once again he would have to cross worlds to get answers to his problems, but it didn't mean he had to do it alone. He smiled as Sara looked back at him.

- Do you want to come with me?

- Sure, why not? I always wondered what super Earth was like.

- Let's go then... We will need Cisco for this.

They were about to go back inside Star Labs when they heard a noise and looked back. It was really dark and the wind was strong that night.

- Long time no see, my love

Sara took a few steps closer to the person who said that, looking completely shocked when she realized who that was.

- Nyssa?

Barry crossed his arms, intrigued. He wasn't a fan of anyone at the League of Assassins, even if Nyssa had fought beside them in the past. He couldn't trust that woman.

- You're hurt... - Barry said taking a few steps closer, stopping beside Sara.

- I had the unpleasant visit of Merlyn! That bastard was dead, wasn't he?

- Yes, but this is another version of him...

- What nonsense is that now? - She looked incredulous at Barry.

- Time travel. Hard to explain. – He kept his serious face.

Sara seemed shocked and bothered by Nyssa's presence. Ever since Sara came back to life, years ago, she wondered about her ex, how was she, was she happy? Sara never looked for her when she got a second chance to live, she joined the Legends and her life turned upside down since then. The look in Nyssa's eyes was of pure hurt mixed with surprise.

- Malcolm got the League back together and they found me. They think I'm a traitor when I turned down his proposal of joining him in some sort of group, I don't know... He said big things are about to happen, and when I said no, the bastard attacked me!

- We are investigating this group and their plans so we can stop them...

- Oh, good luck love – Nyssa interrupted Sara – You'll need.

- Looks like you lost faith in me – Sara said, holding Nyssa as they walked back inside Star Labs, Barry following them in silence.

Once back, Sara took care of Nyssa's wounds while they talked. It felt weird, for both of them, but they ignored it as they had urgent matters on their hands. Nyssa thanked Sara for her help and promised to help them in case they needed. Sara said goodbye and walked outside, near the huge hangar they had in the facility. Barry watched as Sara left, feeling something was bothering her. He could leave her to her thoughts, or try to help. He decided to follow her, and found her sat in a chair, looking at the ceiling and taking a few breaths.

- I'm ok, Barry. You can go back now!

If there was one thing that Barry could see, it was that Sara was not ok at all. He looked at her and thought about what to say.

- I don't believe you.

Sara looked at Barry with a death stare. He didn't back down.

- I know you like to be tough and hide your feelings, I noticed that the day I met you, but I know underneath it all, you are not ok. And there's nothing wrong with that...

- No Barry, there is! – Sara got up abruptly, snapping out of her thoughts. – I wasn't supposed to care! She's my ex, I left, I died, came back, never looked for her to say that I was back to life... And now I see her, that hurt... I wasn't expecting that... Things were bad when I left her, and even if we are not together anymore, I care about her... And now... I don't know... I'm just... - Sara sat again, massaging her forehead, trying to relax.

- Do you still love her?

Barry looked deep into Sara's electric blue eyes waiting for the answer. He didn't know why this mattered to him at least, but he asked anyways. Sara looked back at him.

- We need to go to Kara's Earth.

Sara got up again and started to leave when Barry reached for her arm and turned Sara back to him.

- Do you still have feelings for Nyssa? – He asked again, face inches from Sara's.

She looked at him with a curious look, surprised by his tone. It had genuine curiosity but something else hidden underneath. His hand held her softly by the arm, almost caressing it and his eyes yelled determination. She remembered the moment they had before his phone rang, and given the fact their lives were crazy, she felt like it would be hard to have another opportunity of being just the two of them like this. She never thought about Barry that way, but lately, she has been wondering. He was definitely more mature than the last time she saw him, she could see he was not in love with Iris West anymore since she was married to another guy now and happy, and something about him sparkled her interest. Her fingers touched his cheek and she looked determined back to him, approaching her lips to his. Her lips barely touched his; she stood there, her lips playing with his like a slow dance, barely brushing over it, but never fully diving into.

- If I did, I wouldn't be doing this, would I? – She whispered, showing a sexy half smile that made Barry felt like he was really dizzy.

- I guess not. – He said, barely able to move.

- So, there's your answer. – She gave one step forward, her lips going to the base of his neck – We have a mission now – She said in a low voice – We can finish this later. – She said brushing her lips slightly near the base of his ear.

She could feel his light tremble and smiled to herself, turning away.

- Let's go, Allen, the breach won't open itself!

- Yes... Sure... - Barry said as he got out of his torpor, walking behind Sara towards the Lab.

Once inside Star Labs, Sara and Barry found Cisco pacing around like crazy, talking to himself.

- Cisco? – Barry said as he reached for his friend – What happened?

- Thea called. I told her about Reverse Flash being after criminal files and she told me that Laurel and her found one of those criminals... Dead in the hospital, but missing a few organs.

- Oh my... - Sara said as she covered her mouth

- They are like 10 steps ahead of us, and I don't like it. – He said scratching his head – Please tell me Oliver and Kara have some news?

- They do. They found the base Kara was being kept, everyone was killed. They found Anatoly and he only told them a name... Doomsday.

- And according to Kara, the answer to who Doomsday is lies in our Kara's Earth... - Sara said – So we need to go there.

- I'll look for something here in the meantime. – Cisco said as he gathered his device and opened up the breach. – We can't waste time guys, so please hurry.

Sara and Barry entered the breach, finding themselves in the middle of the DEO with a bunch of guards pointing their guns towards them. Barry and Sara looked around with both their hands in the air.

- We swear we come in peace – Barry said.

Alex approached the scene, looking at Sara and Barry with surprise in her face. The guy she thought she knew, she was sure it was her sister's friend, The Flash. The woman, she had no idea who that was.

- Are you Barry Allen?

- Yes...

- I'm Alex, Kara's sister. – She looked around – It's ok guys, they are friends.

- Thanks – Sara said feeling relieved she wasn't going to unleash her fury on those poor guards. – I'm Sara Lance.

- Nice to meet you – Alex and Sara shook hands – It's everything ok?

- Not really... Can we talk?

Alex brought Barry and Sara to a private room of the DEO. J'onn, Lena and Clark were there talking about something important and Alex introduced all of them.

- So you guys are the famous heroes Kara talks so much about? – Clark said shaking their hands. – Welcome.

- I'm Lena Luthor, Kara's best friend.

Barry reached for her hand, feeling a bit uneasy. He had no idea anyone else knew Kara's secret. He has heard about Lena before, but back then, she was unaware Kara and Supergirl was the same person.

- I know this look – Lena said – It's ok. Kara told be about a month ago...

- Oh... Ok... - Barry said as Alex called his attention.

- You wanted to talk about something...

- It's Kara around? – Sara asked

- She's visiting her mom in Argo City, that's why I'm here now, to help while she's there... But she's coming back tomorrow – Clark said.

- Oh well... We met our Earth's version of Kara... At least I guess so – Barry said.

- What? Another Earth? – Lena looked confused at Alex.

- Oh, I forgot... They are from another Earth – Alex said, making Lena look incredulous at them.

- But that's not the main point... We are dealing with a group of super villains and a telepathic Gorilla and we are trying to figure out their plans... - Sara kept talking, having no patience for small talk at all. They couldn't waste time - Kara and Oliver went to the place Oliver found this Kara and everyone there was dead except for a man that said a weird name... Doomsday.

- Doomsday? – Clark said looking horrified at Sara.

- Yes. Kara told Oliver the answer was here... So here we are...

- Indeed, it is – Clark said walking towards Barry and Sara – You have no idea the danger your world is about to face.

Barry felt like sitting down, his head started to spin. There was a huge danger, again. What else was new? He though. He looked at everyone in the room, feeling really tired.

- Can you please tell us about him...or it?

Clark nodded with his head and Alex opened a file on the big computer screen on the wall. It showed a monster and some information about him.

- He was genetically-engineered from the depths of pre historic Krypton. He is a destroyer of worlds and it's really hard to beat him up. He can't be killed the same way twice.

- He's like...immortal? – Sara said with a worried look on her face

- Not immortal... But it's almost impossible destroying him. I faced one in this world once and if the one in your world is anything like that, you guys will need plenty of help.

- We can come – Lena said – I can bring L-Corp resources that helped Superman in the past...

- I defeated him here, I'm sure we can do again there – Clark said and Alex nodded with her head.

- So the three of you go. I'll stay here with James and Supergirl. I'll tell her about the news. – J'onn said, getting up from his chair.

Lena and Alex went to grab whatever they needed to help and Clark gave them a ride so they wouldn't waste any time. Sara and Barry waited at the DEO.

- Its surreal. – Sara looked around, impressed – They really make things happen here...

- Yes, it is... - Barry said as they reached the balcony.

Sara gave a few more steps, observing National City.

- Look at this view...

- I know

Sara noticed something different in Barry's voice and looked behind her, just to see Barry staring deeply at her. She blushed slightly, getting what he meant and smiled. That Barry was something else, she thought.

- The view from here it's amazing – He said, still looking at her.

- Barry...

- What? – He gave her a small laugh. – We are in the middle of a crisis but we still can enjoy small things in life...

Sara looked at his lips and then back at his eyes. Barry took a few steps towards her, stopping inches from her.

- We need to stop this... - Sara whispered.

- This what? – He said as he reached for her waist, bringing her a bit closer.

- This teasing...

- You're the one who started...

- I know... And it's driving me insane, I confess...

- Good to know – Barry said as he approached his lips from hers – If we weren't in the middle of a government facility in another Earth, full of strangers, I would kiss you...

- Screw the strangers! – Sara said, her hand caressing his neck, pulling his face closer to hers.

She was so tired of running from what it was obvious to her. At first she wasn't sure, she was just playing, but then something changed. She started to really see Barry. And she felt surprised by what she saw. She would never in a million years think that one day she would be kissing him like there was no tomorrow, but here she was. She felt Barry giving into their kiss, their tongues danced together. She broke the kiss apart and stared deeply into his eyes.

- Now we go back to the mission... - She smiled – Let's keep this low for now...

- At least until the craziness ends... I agree – He said taking a few steps away from Sara, also smiling.

It didn't take long for Clark come back with Alex and Lena. Barry and Sara joined them and Barry opened the breach back to Earth 1.

Back in Russia, Oliver was sat on his bed, looking at the balcony and the dark sky outside. The doors of the balcony were open and the wind brushed his face slightly. He closed his eyes when he felt sweet lips exploring his shoulder.

- I'm sorry I scared you... - Kara whispered.

- It's ok. – He opened his eyes and turned a bit back to his side – It worked. Barry found help on Earth 38. He just texted me.

- We leave early in the morning... - She said looking into his eyes.

- Yes...

- For now, we go back to where we were... before the world goes crazy once again and we go back to our lives...

Oliver looked at Kara, thinking about what she was saying. Her kisses on his shoulders weren't helping, so he closed his eyes once again. Her kisses went for his neck and Oliver reached for her neck, his hand getting lost in the middle of her soft golden locks. Oliver opened his eyes and brought her face towards his, kissing her fully on the lips. His body twisted to its side, covering her body slowly as he guided her towards the pillows. Kara's head rested on it as she felt his muscular body covering all of her, pressed against her skin.

The world was going crazy anyways, for now, they would enjoy each other.
