Hello this is my second fan-fiction ever so I am not the best but I hope you enjoy. Also if you like, dislike or have any suggestion please review. If you hate it tell me what I am doing wrong. This starts a Kara x Mon-El and Barry x Iris and become and Barry x Kara. I am going to keep it at T rating. It is at T rating because i am paranoid. Also if you would like to see any other romances in future chapters let me know. It may take me a while to do the next chapter because I am working on another fanfic called 'project redemption mcu'. If you like this, you can also look at project redemption mcu which is basically an avenger movie universe version of suicide squad. Also I can't promise I remember every single line in 'duet' because I don't but I will try my hardest to get the lines right.

"…" ordinary speech.

'…' thoughts.

When a character is signing and there are brackets around a word it just means it is repeating.

Please with icing on top review and enjoy.

Kara P.O.V. (point of view)

"Wow this inter-dimensional extrapolator device is incredible this Cisco guy must be awesome, I hope I can meet him some day," Winn says as he admires the breach opening machine.

"You would be like brothers within the first minute of meeting," I say.

"Just what we need the nerd twin," Alex teases and I can't help but smile.

"You know what I could use an inter-dimensional post break up holiday," I reply and Alex puts her hand on my shoulder and Winn looks at me symmetrically.

'I can't believe Mon-El has been lying to me for nine months, I have never felt so betrayed,' I think to herself.

"We have a new alien prisoner," Hank/ J'onn/ Martian man hunter says.

'Something doesn't feel right between me and Mon-El but for some reason thing never did feel completely right with Mon-El,' I think to herself.

Then this human looking life form walks in and stares at me before saying, "Oh their I have been looking for you," the human like life form says looking straight at me.

"Me?" I ask.

"Yes you," he says as he stares into my eyes and I start to feel dizzy.

"Kara are you alright," Alex asks as she can tell something is wrong.

Then I feint.

Meanwhile on earth 1 Barry P.O.V. I am sitting on the couch in Cisco's apartment watching Singin' in the rain. "Barry how about we go get ice cream or go out somewhere with Caitlin," Cisco suggests.

'I haven't been able to stop thinking about things with me and Iris since she called off the engagement,' I think to myself.

"No I don't feel like it," I reply.

"Come on you haven't been doing anything except watching musicals since you know what happened," Cisco says referring to Iris calling off the engagement.

'I have been thinking are me and Iris a good relationship,' I think to myself.

"What is it with you and musicals these days?" Cisco wonders out loud.

"Everything is better in song," I quote my mother.

Cisco was about to say something when both our phones beeped and we saw a message. The message says 'breach opening.'

In alarm I super speeds off carrying Cisco all the way to the breach room. "Ask first next time," Cisco complains.

"Focus Cisco can you stop it?" I ask.

"No," Cisco says shaking his head.

"Then we see who it is if it is an enemy attack and if it is someone we don't know watch carefully," I say.

Then three people emerge out of the breach. One was hank who I meet the first time I went to earth 38. Then there was someone else who I didn't recognize who was holding an unconscious Kara in his arms. 'Sleeping beauty," I think to myself.

I looked around and no one seemed to notice I was slightly blushing. "Is Kara okay," I ask.

J'onn and the other person who is called Mon-El explains to us what happened to Kara. I got a bit jealous when Mon-El told us he was dating Kara and surprisingly felt relief when J'onn says that they broke up. "So why did you guys come to us," Caitlin wonders out loud.

"Before this man left he said he was going to chase down the fastest man alive," J'onn says.

Then they heard someone from the monitors and rush over to see a person in the speed lab. "This him," I ask and J'onn nods.

I super speed into the speed lab in my flash costume. "Hello Barry Allen," the person who whammed Kara says to me in a song voice.

"How do you," I say before he interrupted, "Your name, I know a lot of things."

Then I see Kid flash run into the speed lab. "Wally West, Kid-Flash welcome to the party we are happy to have you," the man who whammed Kara says with excitement in his voice.

'How does he know our names and more important question, how do we help Kara,' I think to myself while gritting my teeth.

"But you haven't been at the best you have been you seem a little scared," the man who whammed Kara says.

"I'm not scared of anything especially not you," Kid-Flash says and then the man who whammed Kara charged at Kid-Flash at super speeds nocking Kid-Flash to the ground.

Then I run at the man and he grab me by the neck. "And you are too slow flash," the man says before his eyes start to glow and I feel tried.

My eyes drift asleep. My eyes quickly open to find that I am not in star labs any more. I am in some sort of night club. I hear a familiar voice singing and I look up to the stage to see it was Kara singing. "Moon river, wider than a mile," Kara sings in a black sequin grown. 'Wow she looks amazing in that dress,' I think to myself while looking at her stunned.

"I am crossing you in some stile, oh dream maker, you heart breaker," Kara sings enchantingly.

'And her voice,' I think, 'She is the most beautiful women ever meet as well as being smart, kind, funny, independent and now she is an amazing singer what can't that woman do.'

"Wherever you are going I am going your way," Kara sings.

"Two drifters off to see the world," Kara sings and I can't help but look at her in awe.

'Barry focus you already have Iris,' I think to myself.

"There's such a lot of world to see," Kara sings.

"We're after the same rainbows end," Kara signs and I noticed she stuttered at a bit.

Then I noticed she was look at me and I waved my hand. "Waiting round the bend," Kara signs.

"My huckleberry friend," Kara sing, "Moon river and me."

When she finished the song I saw her go to off stage. I run over their but I notice that my powers are not working.

Kara P.O.V. I see Barry come through the back stage doors and towards me. "Barry it's you," I say before hugging me then she let's go and asks, "it is really you?"

"Ya, what is going on, where are we and why don't our powers work?" Barry says.

"I wish I knew the answer to any of those questions, how did you get here?" I answer.

"Well when you got whammed J'onn and your boyfriend came to our world with you the guy who whammed you followed and whammed me," Barry explains.

"He is not my boyfriend, he's my… nothing," I say stuttering a bit.

'That was so embarrassing,' I think to myself.

"Maybe we are dreaming," I hear Barry say.

"The same dream?" I question.

"Oh, how do you think we could get out of this wherever we are," Barry says.

"Well maybe I could click my heels three times," I say sarcastically.

"Ya," Barry says completely serious.

"I was kidding," I say and I hear an oh sound escape Barry's lips as he looks down in embarrassment.

'Barry is so cute and handsome and funny,' I think to myself.

"Maybe we're in an alternate universe and the transportation blew out our powers," Barry suggests.

'I have to stay focused,' I think to myself.

We start to walk out and into the main room where everyone eats and listens to music. We then see the person who whammed us. "Beautiful absolutely beautiful even though you stuttered but you are so cute that I will forgive you," the man who whammed us says.

I loss control of my anger and punch him in the face to my surprise my fist goes through him. "A swing and a miss, I forgot to mention I am not really here," the man who whammed us says.

"So where are we then," Barry says.

"We are inside your head," the man who whammed us says.

"I have had enough of mystical creeps," I say.

'I can see why,' Barry thinks to himself.

"It could have been an alien war or a wild west shoot out but it is luckily a musical and we have to thank the countless times you have watched wizard of Oz with your adopted family Kara or Barry you watching Fred Astaire and Frank Sinatra with your mother," the man who whammed us says.

"So where are you?" I ask.

"Out in the real world where I can do whatever I want," the man who whammed us replies.

"We are going to get out of here and stop you," I say.

"How?" the man who whammed us questions.

Nether me or Barry could answer.

"I'll tell you how you can get out just to make this fair and fun," the man who whammed us says.

"How do we get out," both me and Barry say in unison.

"You are in a musical all you have to do is follow the," the man who whammed us says before I interrupt, "Yellow brick road."

"No, the script," the man who whammed us says.

An oh left my lips as I felt embarrassment that I got something wrong in front of Barry. 'Wait do I have a crush on Barry,' I think to myself.

"Alright, are you ready to sing?" the man who whammed us questions.

"No we aren't going to sing for you," I say and both Barry and the man who whammed us looked at me.

"Anymore," I correct realizing the mistake I made.

"Come on let's start this with an opening number," the man who whammed us says while taking off his shirt and throwing it on the ground.

Me and Barry complained but he started signing over us. "Think of your fellow man, lend him a helping hand, put a little love in your heart," the man who whammed us sings as he walks up to Winn who is sitting in front of a piano.

"You see, It's getting late, oh, please don't hesitate, put a little love in your heart," Winn sings while playing the piano.

"And the world (the world) will be a better place, and the world (the world) will be a better place, for you," Cisco sings.

"And me," Winn sings.

"You just wait," Cisco signs.

"And see, oh yeah," Winn sings.

"If you want the world to know we won't let hatred grow put a little love in your heart," Malcolm Merlyn sings.

"And the world will be a better place and the world will be a better place for you," the man who whammed us sings.

"And me (and me)," Winn sings.

"You just wait," Malcolm sings.

"And see," both Winn and Cisco sing.

"You better take a better look around Oh, if you are lookin' down put a little love in your heart," Winn sings.

"And the world (and the world) will be a better place," Cisco sings.

"All the world (all the world) will be a better place," Malcolm sings.

"For you (for you) and me (and me) you just wait (you just wait) and see," Malcolm, Cisco, Winn and the person who whammed us sing.

"Put a little love in your heart," Malcolm, Cisco and the man who Whammed us sing.

"Put a little love, put a little love," Winn sings.

"Put a little love in your heart," Malcolm, Cisco and the person who whammed us sing.

"Put a little love in your heart," Winn repeats in his singing voice.

"Put a little love in your heart," all four of them sing in unison.

"Put a little love," Malcolm sings.

"Put a little love in your heart," all four sing in unison.

"Come on and," The man who whammed us sings.

"Put a little love in your," the four sing before the man who whammed me and Barry finished the opening number off, "in your heart."

Then everyone started doing something else entirely except the person who whammed us who disappeared. "Where did he go?" Barry questions.

"I don't know he was their just a minute ago," I say.

Then we saw someone walk over and by the way Barry looked at him it was someone he knows. "Malcolm," Barry says.

"Who?" both 'Malcolm' and me ask.

"Malcolm Merlyn head of the league of assassins," Barry whispers to me.

"The name is Cutter Moran and I pay you to sing not pepper me with questions," 'Malcolm' says.

Then Cutter looks directly at me. "And I pay you to sing something original, Blondie," Cutter says.

"Don't call me Blondie," I reply angrily.

"Who do you," Barry says before being interrupted by Cutter pulling out a knife.

"Sorry about my friend he doesn't know when to stop talking," I say trying to make sure Cutter doesn't kill ever of us.

"Ya I had a cousin like that I had to slit his throat too," Cutter says and even without my super hearing I could hear Barry gulp.

"Grady," Cutter calls out and Winn comes over.

"Winn," I say.

"The names Grady, doll face," Grady (who looks like Winn) says.

I control my anger to stop myself from punching him in the face. "Grady will work with you on the pianos when you get a song which is an original," Cutter says before leaving.

"Do you know why they call him cutter, It's because he likes to cut people," Grady says.

"He really isn't as scary or dangerous as he claims to be," Cisco says as he comes out of nowhere.

"I hope he doesn't hear that Pablo, for your sake," Grady says.

"One day I am going to be someone and it is all going to happen on that stage I am just waiting for my one chance," Pablo (who looks like cisco) says.

Then me and Barry go up to the singer's room. When to two oddly suspicious guys walk over. "Hello," Barry says.

Both of them pull out their guns and aim them at the two powerless heroes. "We don't want any trouble," Barry says.

"I miss being bulletproof," I complain before the gangsters knock both of us out.

To be continued….

I hope you enjoyed. The next chapter or two will be about duet but then will be about flash and super girl series. If you have any ideas or suggestions, they would be greatly appreciated. Also sorry that I didn't get every single line in duet the same but no photographic memory. I might not update for about a month because I am busy working on project redemption. Also if you would like me to include any other romances that weren't in either show tell me. Also I think I should skip the Kid-flash, vibe and Martian man-hunter vs. Music-Meister. Please review and keep your eye out for next chapter. Ant boy out.
