Chapter One: Bittersweet

Sometimes when you are having a hard time dealing with several issues you want to drop everything and run as far and away as you can. Take a break of everything and everyone in the world just for a moment, and yes, it is selfish but sometimes we need to be selfish. Take a moment for ourselves to figure it out what we need, want or have to do. And when you're feeling like that the most amazing thing that could happen to you is to have someone who understands you or at least try to do it. Someone who stands by your side and tells you ' you're going to make it through this, just hang on'. You must be very grateful with the universe, God or whatever you believe in for put a person like that in your way. Because having someone like that it provides you a refuge, hope and love.

It was in a moment like that when Kate and Kara's friendship blossom. When they first met they knew that they could be a great team, working together it would be awesome and extremely fun. But it wasn't until a particular rough day that Kara realize Kate and her could have an amazing friendship.

That day was when Alex choose to erase her memories to protect her sister. Kara felt the loneliest person in the world. She even couldn't speak to her closest friend, Lena, about what was happening, as she would lose her too. Because telling Lena it means she had to tell her that she had been lying since the beginning of their friendship.

So, Kara flew, as far as she could, trying to run away from everything that caused her pain but it wasn't enough. She wouldn't find comfort in any place of the world. And just like that occurred to her that maybe she could go to someone who wouldn't be in danger for knowing all about her. Someone who doesn't live on Earth 38

She went home to pick up the device Cisco and Barry gave to her, crossed through the portal and appeared on earth 1, somewhere near Central city.

Kara was standing at the top of a building thinking about her possibilities. Go to Star Labs it seemed a reasonable idea, but she didn't want to be surrounded by many people asking what was wrong. Going to star City wasn't an option either so her only option was going to the last place where someone knew her on this earth, Gotham. Kate would receive her without doubt. Besides she will listen to her if she wanted to talk. Therefore, she went to boatwoman's city, hoping to find Kate at Wayne's tower. It was almost evening when Kara landed on an alley near the building. Her plan was simply, go inside, take the elevator and walk in on Kate's office and say, 'I was on the neighborhood and decided to say hi'. Which, of course it would be the most stupid thing she could say. But when she set a foot in the hall a guy appeared. He didn't see her right away because he was concentrated in the tablet he was carrying.

Surprised by the fact of finding someone except Kate on that place and now seeing how clean it was, Kara wondered herself if she hadn't gone inside the wrong building. She was about to say something when the man realized she was standing there.

- I think you got the wrong place miss – the man said.

- It may be so; I was on the city and decided to drop by a friend's office

- Definitely the wrong place - Luke said with amusement, after all Kate hadn't been on the city for a long time and the place wasn't working since Bruce left the City three years ago

- Just to know, we aren't at Wayne's tower, right?

- Actually, we are, which is why I'm surprised you are here

- I don't understand, why it would be strange? - Kara asked confused

- It is just this place was practically closed for the last years, and we recently star to reopening, are you friends with Bruce?

- Bruce? No, I was looking for Kate, his cousin, we met recently.

- That's interesting, meting a friend of Kate I mean... But she is not here right now

- You know if she will be back? I really wanted to see her.

- I could call and ask her, what's your name?

- Oh yes sorry I didn't introduce myself, my name is Kara, Kara Danvers. I would appreciate if you call Kate...

- Luke, my name is Luke, - he said offering his hand to shake

- Nice to meet you Luke, you're a life saver, I would be a shame can't see Kate when I'm in her city

-Happy to help, Kara

He took his phone to call Kate, who had to be out there like batwoman beating criminals, when he said -

-So, you don't live here, did you make a long way to get to Gotham?

-You could say that- Kara answer amused

Kate didn't pick up the phone, but Kara heard noise near her office floor and smiled, Kate was back. -Before Luke could notice she slip in the elevator and said

-Don't worry I'll wait in her office - She shout at the time the door started to close

-Wait you shouldn't - the doors closed- go in there. - Kate is going to kill me he thought before running to get in another elevator.

Luke reached the door office just in time to see Kate coming out of the secret entrance to the bat cave which means Kara totally see it.

Before any of the two women had the chance to say something, he provided an excuse

-That's the entrance to a panic room of course, since this is the CEO office

Both shared a knowing look and smile.

- Yeah, the safest place in the city, it's like having batwoman with you in there - Kate said just to make fun of Luke, his face was priceless.

Kara go along and added

- Somehow, I feel more secure now because she come out of that room

Luke didn't want to open his mouth; he wasn't sure what to say so Kate put him out of his misery

-It's okay Luke, Kara knows about me

- I can see it, the two were having fun on me, In that case I'll leave you both to catch up - he left and closed the door behind him but heard Kara saying

- Sorry... Is he mad at us?

- I don't think so ... Now please come, let's sit. I want to know what brings you to my city

-Thank you, and sorry for drop by without telling you before

- It's okay Kara; besides it's not like we live on the same Earth, you couldn't let me know even if you wanted to - Kate said and smirked

- You're right, I'm sure Cisco could find a way to communicate between Earths, or maybe I should ask brainy, even better both could figure out together. But to do it they would have to communicate somehow which is our problem here

Kate listen her rambling and decided to stop her otherwise Kara wouldn't.

-Okay stop there, although I find your ramble very funny, I believe that this issue with communication it is not the reason why you're here, Am I right?

- Right, No, I mean it is not reason - Kara's expression change to one of uncertainty, did she do the right thing coming here?

Kate thought Kara believed her presence was unwanted and clarify

- Don't get me wrong Kara, it is great having you here

- Are you sure? I wouldn't want to be an inconvenience

-Sure, you are always welcome, my cave it's your cave - the last part she said it to make Kara laugh, and it worked

- I would remind it if someday Kal kick me out of the fortress - she answered with amusement

- So, I suppose there's not another maniac trying to remake the world, right?

- No, Thank Rao, we are done with that -

Noticing Kara didn't want to talk about what bring her to Gotham, Kate let it be and proposed

- We should grab some dinner, do you want?

- Sure, I'm starving. I could die if I don't eat soon - Kate laughed at that

- Okay then, I won't let the girl of steel die of hunger, we could go out or stay here if you want. Pizza it's fine?

- I would like to stay here, it's had been a long day... But I must warn you I don't have the appetite of a normal person - Kara said blushing

- I would be disappointed if you do.

They laughed; it was refreshing for both of them being together. To take a break to share with a friend it's always good for the soul and mind as well.

Kate proposed go to the roof of the building, it was nice out there and the night was lovely, so they went there. While waiting the food they talked a little about everything and at some point, their inexistent love life

-After spending several years around the world training to work at crow's security I came back home because of Sophie, she had been kidnapped and I had to do something

- And who Sophie would be...?

- My ex, we had a rough break up and hadn't seen each other since then

- Are you two trying to go back together?

Kate let out a little laugh

- I wouldn't say that, she is married now ... with a guy

- It's sounds like you are me - Kara said and laughed

- And why is that?

- My ex, last year I had to send him away to protect him. He was from a twin planet to krypton; we couldn't stand each other when we first met but eventually, we solved our issues and started dating.

- You said my story with Sophie it reminded yours, why is that?

- I had a really rough time making amends with the decision I made, I even tried to stop being Kara and focused on being Supergirl.

- That part sounds like me running away.

- Yeah, that may be so.

- Do you know anything about what happened to him.

- Yes, and that's the part where our histories are alike. - At that moment Kate's phone sounded

- Wait a minute, the delivery guy just got here.

- That's the best thing I heard today.

- Sounds like the food is the path to Supergirl's' heart.

- I knew you would make fun of me, go grab the food before I overcome you downstairs.

- That wouldn't be fair, and you know it. I'll be right back on a moment.

Less than five minutes later Kate showed up with several boxes of pizza, and some beers.

- I didn't ask, beer it is fine to you? I could get you other thing if you don't like it.

- Don't bother, although I can't get drunk, beer is fine.

- You're kidding.

- Nope, Kryptonian metabolism is to fast so earth alcohol affects me.

- That must sucks - Kate said faking horror - Wait you said Earth alcohol as in human alcohol, is there alien alcohol in your earth?

- Yes, there is, National City has an alien bar, my friends and I go there sometimes. Actually, Mon El, my ex, used to work there

- Which bring us back to your story, but let's eat while talking. Im starving-

- That sounds like and excellent idea- Kara said at took a slice of pizza, the first of many - Where was I?

- You were saying you knew what happened with Mon El. - Kate took a sip of her beer and took a slice of pizza

- Oh yes, I remember. Well, several months after he had to go, we find him on the city. He was fine and married.

- Seriously? How did that happen?

- Somehow, he went through a worm hole, and landed on earth on the year three thousand, lived there, became a real hero and got married. For me it had pass seven months but for him it was seven years.

- Wow that's a lot, I can't imagine what you felt.

- I was shocked at first and glad he was alive. And mad at him as well, because he had changed so much, he was the person I knew he could be and never had the chance to meet. Finally, I realized that I had been idealizing our relationship, I made peace whit that and move on.

- I'm going to ask something, and you don't have to answer if you don't want to. Did you love him?

Kara was silent, looking the stars, thinking about how respond that question. She owed herself be honest about Mon El, besides Kate wouldn't judge her, she was sure about that.

Kate respected her silence and look to the sky as well. She wouldn't pressure Kara to talk about something she didnt want to or made her feel uncomfortable so she joined her friend in the silence and waited. After several minutes Kara look at her and said

- I believe I loved the idea of having someone who understood what it was like to be an outsider, someone who could understand the pain of losing everything, your family, friends, your planet and even yourself. The difficult that it is having to adapt to a new life and hide a part of who you are. I really cared about him; I still do. But I didn't love him for who he was, I loved him for what he represented to me.

Kara sighed and let out a little smile.

-What is it? -

- I never had said it out loud, it's so liberating

- Some people told me that is not healthy to keep those things inside, you need to have someone to talk.

- I think I just find someone who will listen to me, but there is a little problem

- And what that would be? I'm sure it has a solution and you would find it - Kate reassured her

- We live on different earths that's the matter, but you're right we will figure it out

- That was so sweet, people should tell you the girl of marshmallow - They both laugh out laud.

- I propose a toast for that and for being here - Kara said smiling

- Cheers to that, marshmallow girl. By the way, you believe your friends could find a way of communication between Earths? –

- I really hope so, it would be like the best present ever. I'm sure Lena could figure it out, but I can't ask her.

- Who is Lena? – Kate asked intrigued why Kara couldn't' ask someone who could find a solution, her help.

- Lena is my best friend, she is a genius, CEO of her company, L-Corp. She is always trying to help people, she even helps to save the city a couple of times, and She is who made me realized I wanted to be a reporter. - Kara smiled at the memory.

- It seems like she is amazing

- She is, despite all she has been through she still is one of the best people I know,

- Why you can't ask for her help?

- Because Lena doesn't know Kara and Supergirl are one and the same. And Supergirl shouldn't ask her help with a personal issue. Because they are no friends, not anymore. At least that was what Lena said. – Seeing the confusion on Kate's expression Kara added - Ours families has history, a complicated one, and she and I, Supergirl, were friends and I messed up so bad. I betrayed her trust. It's a long story, I will tell you all about it someday.

- It is never easy having to lie, to hide a part of who you are to someone who you care about. And I don't know how you messed up but everyone makes mistakes, even your friend and eventually she will understand your reasons. And if she is as amazing as you said she is she will give you a chance to rebuild what is broken between both of you.

Kara felt that was the moment to speak about the reason why she came to this earth. She took a deep breath and said

- And now I have to lie to Alex, my sister as well. I didn't want to, but she did it to protect me. She always protects me.

- What are you talking about?

-My sister asked to our friend J'onn, to make her forget about me being Supergirl. She works for the DEO, the department of extranormal, the agency with I used to work.

-Why she would do that? What happened? - The concern in Kates 'voice was evident.

- There is this group, the children of liberty, who hate aliens. They persecute people from another planets, discriminate them and even have dogs trained to hunt aliens. Even the president support some of their ideas and asked me to reveal my identity if I wanted to keep working with the DEO, otherwise I had to leave. I couldn't tell him who i am, and now I became in a public enemy or something like that.

Kate pass of being concern to really angry on a few seconds, she couldn't believe what Kara was saying

-That's bullshit, that man lost his mind. I don't care if the guy is the president, he can't ask you to reveal your identity. He should be grateful for everyone you have done, you shouldnt be persecuted. It's like he chose on purpose ask the only thing you can't do. Because you know if you do it, eventually the people you care about, the people you love, will be in danger.

- That's the reason why Alex had to forget who I am. They are making interrogations at the DEO, to find out if someone knows my identity. Of course, she wouldn't say anything willingly, but they are using an alien creature, a truth seeker. She wouldn't have choice if they ask her.

- So, she decided to forget, to protect you... She really loves you. I can't totally imagine what you are feeling. I know it is not the same, but I promise you I'm here, you're not alone. You will find a way to fix this and until then you can rely on me. I meant it when I said you are always welcome here. I love having you here, even if you eat all the pizza - The two laugh with the last comment.

Kara's' eyes were full of tears but she keeps smiling and hugged Kate as hard as she could without hurt her, and Kate hugged her back as hard as she was capable. Although it was a bittersweet moment it was perfect. They would remind this like one of the most precious moments of their friendship.

-Thank you, Kate, I wasn't sure but coming here was the right decision. – They let go each other and seeing Kara had eat all the pizza, Kate asked her

-What do you think about ice cream and Netflix? You can crash on my couch tonight I you don't feel like going home.

- I would like that very much, especially the ice cream part. And one of the advantages of having me here is that the ice cream never melts.

- And that happens because of the freeze breath or because you eat all the ice cream before it could melt? – Kara pretended to be offended and stood up, and walking to the elevator said.

- That was so mean, you will have to make up for that with tons of ice cream. Chop chop Kate, that Ice cream won't come here by itself.
