Hey guys :) So, how much more fun would that Flash crossover musical episode have been if the Music Meister shipped Kara with Lena instead of that other guy? A whole bunch more fun is the answer you're looking for :)

Also, for anyone wondering what on earth I'm doing posting this when I should be updating 'Surviving', I thought I'd try breaking my block on that by writing something completely unrelated – don't worry, I've not abandoned it!

Also, also, the 'T' rating is because there is going to be at least one Alex POV chapter in this, and we all know that she drops an F bomb every three seconds in her head, right?

Chapter One

Moon river, wider than a mile,

I'm crossing you in style some day.

Oh, dream maker, you heart breaker,

Wherever you're going, I'm going your way.

Two drifters, off to see the world,

There's such a lot of world to see.

We're after the same rainbow's end, waiting round the bend,

My Huckleberry Friend, Moon River and me.

Kara's heart was pounding so hard she was sure that if she'd had her super-hearing it would have been hard to hear anything else. She let the whoops and applause wash over her as Barry gesticulated awkwardly at her from the back of the club.

She smiled and bowed her way off the stage as quickly as she could, almost breaking her horribly fragile and apparently human neck, tripping over the skirts of her dress as she went.

"Barry?" she called as she made it down the stairs, craning around the corner to see him.

"Hey!" he called back, his whole face lighting up.

"Barry! It's you, thank Rao!" She threw her arms around him just in time to feel a surge of doubt that made her pull back again. "Wait, it's really you, right?"

"Yeah, this is me-"

"Good-"

"What is- where the hell are we? What's going on?"

Kara was equal parts relieved and worried by the fact that Barry seemed to be just as confused as she was.

"I was hoping you could tell me or maybe explain to me why I just pulled an Audrey Hepburn and sang in a nightclub."

This is insane. Kind of wish-fulfilling, but insane.

"Maybe we're dreaming?" Barry suggested, his face doing the weirdly adorable squishy thing it does when he has a stupid but fun idea.

"The same dream?" Kara pointed out.

"Yeah, that's- What's the last thing you remember before you got here?"

What is the last thing I remember? Why's it so blurry?

"I-" she hesitated, turning as she searched her scrambled memory. "I was at the D.E.O.," she paced as it came back to her. "They had just brought in an alien prisoner; he got loose, and - it was really weird," her nose crinkled and she gestured towards her collar as she searched for the word. "He had this, um, red-"

"Pocket handkerchief?" Barry supplied, eyebrow raised.

"Yes!'

"I saw you - on my Earth." Kara couldn't not notice the way his whole demeanour darkened. "You were in a coma. Your- your boyfriend brought you to us-"

"He is not my boyfriend!" Kara had to interrupt. Barry had seemed uncertain even as he said it, but Kara couldn't bear the thought of anyone in any world ever thinking that she and Mon-El were together ever again. "He- he's a big, big mistake that is well and truly best left in the past."

He's a lying, selfish jerk is what he is.

"Okay." Barry looked somewhere between confused and sceptical but Kara really didn't want to waste any time explaining further right now while they should really be trying to figure out this whole insane situation. "Alright, uh, well, whoever he is said that this guy whammied you, and then he escaped to my Earth. He showed up at S.T.A.R. Labs, I went after him to try to get him to wake you up-"

"And then you got whammied," Kara finished for him.

"Yeah."

Should probably have seen that one coming, Barry.

I probably would have done the exact same thing.

"So where are we?" Kara asked, trying to address the biggest and potentially most pressing question.

"I don't know," Barry replied, looking around in some frustration. "I mean, it could be a parallel dimension, or maybe just some elaborate illusion. We just need to figure a way out."

"I guess I could click my heels together three times," Kara said, expecting a laugh or an eyebrow quirk, not-

"Yeah!"

Barry's face lit up and she had to stop that train of thought before it got going anywhere.

"I was kidding."

Note to self: less sarcasm.

Lena would have laughed.

No, she would have met my eyes and let one corner of her mouth curl up and-

"Okay, all right, well, come on." Barry tugged on her arm and led her back out through the now-emptying hall. "You're a really good singer, by the way," he said as they made their way towards what looked to be the exit.

"Hey, thanks!" she replied, unable not to grin. "My sister says I put the 'Kara' in 'karaoke'."

They were just making their way up the steps when a tall man in a fancy white jacket approached them, his face an alarming picture of irritation.

"There you are!" he all but yelled at them.

"Merlyn," Barry murmured, his whole body tensing beside Kara.

"Who?" Kara asked almost at the same time as White Jacket Guy.

"Malcolm Merlyn," Barry said, his voice staying low. "Former head of the League of Assassins."

"The what of the what?"

"What the hell you talking about, kid?" Merlyn demanded, his brow furrowing further still. "My name's Cutter Moran. I own this club, and both of you work for me."

"We what now?" Kara and Barry mangled the English language in unison.

"I pay you to sing, not pepper me with questions," Merlyn/Moran cut them off. "And I hope you've got something better in your songbook than what you were belting out up there, blondie."

"Hey!" Kara couldn't hold her tongue any longer after that. "Don't call me blondie!'

"Hey, look, I don't know who you are-" Barry began, stepping forward and then immediately retreating as Moran pulled a flick knife from somewhere, "-obviously you're someone who's quick with a knife."

"You have to excuse my friend," Kara cut in, an awful feeling of vulnerability flooding her as she realised that if she didn't have her powers, there was a strong chance Barry didn't have his either. "He doesn't think before he talks."

"Yeah, I had a cousin like that," Moran sneered. "I had to slit his throat too."

"Oh," Kara said dumbly as she heard Barry swallow hard beside her even without her super-hearing.

"Grady!" Moran suddenly barked across the room. "Get these two set up. And nothing I've heard before; I want something original."

And with that, he strode away.

"Barry," Kara murmured as soon as their 'boss' had left. "I don't have my powers."

"Me neither," Barry replied, his face mirroring the worry Kara felt.

Just keep it together, Kara. This is why you train in the Kryptonite room with Alex. You are more than just your powers.

She took a breath but before she could speak she turned and felt her whole heart leap for joy at the sight of one of her favourite people in all the multiverse.

"Winn! Winn, you're here too?" She reached towards him but-

"Ah!" he immediately recoiled, raising his arms in a universal (or multiversal?) 'hands-off' gesture. "Who's Winn? The name is Grady; I tickle the keys around here." He punctuated this statement with a totally-Winn little hand gesture that made Kara ache with how much she wished her friend really was there. "Say, you realize how he got the nickname 'Cutter', don't you?"

"No."

"Because he likes to cut people."

Kara was finding it very hard to keep a straight face because not only was this Winn-shaped Grady person saying strange things but he was saying them in an increasingly un-Winn-like accent. Thankfully Grady was distracted by a laugh coming from another man with a familiar face just behind him.

"You ask me, I think he's all talk."

"Cisco," Barry's voice rang quickly with hope before fading again, "not Cisco. Hello."

"I pray that, one day, you do not find out how very, very wrong you are, Pablo," Grady said, his face as serious as the old-show-stereotypes were becoming silly. "Now go do your job."

"Alright," Cisco/Pablo said with a flick of his cloth at Grady as the Winn-imposter – Winnposter! Be serious, Kara – left. "You see," Pablo carried on, his face and voice becoming distant and wistful, "Grady doesn't know this but, one day, I'm gonna be somebody. I'm gonna be somebody, and it's gonna happen right there on that stage. You'll see; I just need my one shot."

And with that, he turned and left, leaving Kara and Barry to themselves again.

What the fricking frack!

"It's just curiouser and curiouser," Barry murmured, voicing Kara's own sentiments.

"Yeah," she agreed, her voice coming out almost breathy in wonderment. She'd seen some weird things in her time, but this- this was almost as cool as it was unsettling. "Yeah, it's like "The Wizard of Oz'."

"Yeah."

"'And you were there, and you were there'," Kara mimed, unable to stop herself.

"Except, it's not really them," Barry pointed out. "They're all playing characters in a- a-"

"Musical," they concluded together as the realisation of quite how weird a situation they had found themselves in began to dawn on them.

"Barry, where are we?" Kara asked, feeling fear rippling in her gut as she looked at him.

"I don't know," he replied, his face showing his matching fear.

"Well, you know what they say," a voice suddenly boomed out behind them as the stage lights flicked on, "the show must go on!" Kara and Barry span around to see the pocket-square-wearing jerk who'd gotten them into this mess standing on the empty stage in what had suddenly become a deserted room.

"Ah-!" Kara apparently couldn't find the words to reprimand him with as she pointed a finger in wrathful rage and started towards him.

Alex would have some words for him, I bet- Ooh! No, Lena! Lena would know what to call him- Or she'd raise one eyebrow at him like she does sometimes and her voice would go all low and angry and-

"Supergirl, I loved your rendition of 'Moon River'; such a beautiful song. You were a little flat in places, but I'm willing to let it slide just because you're so cute." He hopped lightly off the stage as he finished and Kara's indignation was really reaching boiling point by now.

"Hold on," Barry started, irritation clearly lining his voice. "What did you do to us?"

"Oh, nothing much," Jerk-Guy said with a smile, brushing past two superheroes like it really was nothing. "Just put a little song in your heart."

"'Put a little-'? Why did you bring us here?!" Barry was apparently better able to find words for his indignation than Kara was.

"I didn't bring you anywhere," Jerk-Guy replied, practically grinning now. "We're inside your heads; you created this world." He stared around at the stage and the lights and the bar and the tables. "And we got lucky because it could have been a war movie or a- a space opera, but thanks to your love of musicals, with the countless times you watched, um," he closed his eyes for a second before opening and pointing at Kara with, "'Wizard of Oz' with your adoptive parents-"

"How did you know that?!" Kara burst out, unable to keep it in any longer.

"And, you," he turned to Barry, ignoring the Girl of Steel and her outrage, "all those rainy nights watching Fred Astaire and Frank Sinatra with Mom. Well, where else would we be?"

"All right," Kara practically growled, "all right-" She strode forward, looking to deal with this problem the best way she knew how and threw a punch at him with all her might. She might not have her powers but she still knew how to throw an excellent right hook.

Except, apparently, when her opponent could phase out of corporeality at will.

She grunted with the effort of keeping her balance in the shock of her fist meeting no resistance.

"Ooh!" Jerk-Guy cried, his voice high and excited as he phased back into being. "A swing and a miss! I didn't tell you: I'm not really here. See," he explained, his voice doing that condescending villain thing that Kara found really, really annoying, "I'm out there in the real world. Central City's mine for the taking."

"Uh-uh," Barry interjected sassily. "We're gonna stop you."

"Yeah!"

"You're welcome to try that," Jerk-Guy said congenially, "if you can get out of here."

Well that's kind of the issue, really, Kara had to admit.

"How do we get out of here?" she asked through gritted teeth.

"You're in a movie musical," he explained, his eyes darting from Kara to Barry and back again. "So, all you have to do is just- Follow? The?"

"The Yellow Brick Road?" Kara piped up almost automatically.

"No," he said with a patronising little smile, "the script."

"Oh," Kara hoped her face wasn't burning, "yeah. Script."

"Reach the end of the plot, and," he held out his hands with a smile, "presto chango, you get to go home. One little detail, though, I should mention if you die in here, you die out there." The little smile that accompanied this piece of news was just what Kara didn't need.

"Lovely," Barry said with a grimace.

"I've reached my limit with magical creeps," Kara muttered, wondering with half a mind where all these guys came from and how they always seemed to find her.

"In the meantime," Jerk-Guy said expansively, "I hope you're both ready to get the rust off those pipes of yours."

"We're not singing for you!" Kara objected, fists on her hips with indignation.

"No!"

"Uh, any- anymore, I mean." Even if it was a little wish-fulfilling up on stage there…

"Come on, now," Jerk-Guy wheedled as he began to remove his jacket, "maybe just one little fun opening number, just to kick things off!"

"Leave your jacket on-" Barry tried to interrupt him, to stop the inevitable song that was coming, his face scrunching when the jacket seemed to just vanish into thin air as Jerk-Guy threw it aside. "Where did it go?"

"Think of your fellow man-" Jerk-Guy began to sing.

"Stop that," Kara said, closing her eyes in an attempt to pretend it wasn't happening, just as Barry said-

"It's not happening-"

"Lend him a helping hand-"

"It's not gonna work." Even if he does have a lovely voice- No!

"We're not singing!"

"Put a little love in your heart!"

And then the musical began in earnest.

Kara stared around, her eyes bulging as Winn/Grady joined the singing even as he expertly 'tickled the keys', and then Cisco/Pablo and Merlyn/Moran got involved, along with a cavalcade of dancers that seemed to appear out of nowhere, twirling and singing all in beautiful harmony together.

I wonder if Winn can sing and play like that in the real world?

Really not the important point right now, Kara.

What was worse was that she could see Barry next to her getting more and more sucked into the music, the grin on his face growing, and he even started to almost dance along, trying to mimic some of the moves that the 'performers' were doing.

He's clearly a villain, Barry, he abducted two superheroes so he could have free reign in the real world!

Even if he did just put us in an awesome musical….where they're singing about love making the world a better place…

It's villainous! It's a villainous trick!

And almost as suddenly as it started, the song ended, the dancers and performers all slipping away like a sigh in the breeze. Another flourish of fear and anger burst through her as she realised that Jerk-Guy had completely vanished.

"Where'd he go?" Barry asked, peering through the emptying club.

"I don't know," Kara replied, her hands slapping against her thighs in frustration.

"Come on," Barry sighed out and started towards the exit at the back of the room. "Let's find him."

They made their way through the club, searching the different floors, different rooms and corridors, making Kara really wish she had her x-ray vision or at least her speed, until they found themselves back in one of the dressing rooms that they'd already checked.

"He's gone!" Kara exclaimed in frustration at their fruitless search.

"Yup."

"So what do we do now?"

"I don't know," Barry said with a sigh. "I mean, I guess we just we do what he says, right? We have to figure out what the plot of the musical is and we follow the story."

"Okay," Kara took a breath, hands on her hips and trying to feel more like Supergirl, "uh, so what do we know so far?"

"We're singers."

"And… apparently we work for a gangster." Kara tried not to let the surrealism of this get to her.

"Yes, who wants us to perform for him. I mean, honestly, it's pretty straightforward," Barry concluded, his face scrunching up with the trope-heavy plot.

"Right?" Kara couldn't help but agree, cautiously taking some reassurance from the fact that the plot they were apparently supposed to follow didn't seem to be too complex.

"Yeah," Barry grinned, clearly feeling that same rush of optimism that she had felt.

Their optimism was pretty short lived, however, because almost immediately at that point there came the ominous clicking sound of a gun's safety being removed.

If I'd had my super-hearing I totally would have heard them coming!

"H-hello-" Barry stuttered, his eyes wide.

"Hi!" Kara burst out, fear squirming horribly in her chest. "I miss being bulletproof."

"You're coming with us," one of the goons with guns said in the most stereotypically goonish fashion.

"Says who?" Barry demanded bravely just in time to be clubbed around the head from behind by-

"Says me."

Kara gasped as she turned to see what looked like Professor Stein from the Legends.

I'm pretty sure that's not Professor Stein.

She crouched beside Barry, relieved to feel his pulse still beating strong at his wrist.

"What do you want with us?" she demanded, trying and failing to heave Barry up.

Ugh! If I had my powers right now-!

"You'll have to come with us and find out, won't you," Stein sneered before turning to his goons. "Take them."

And with that, Kara was yanked unceremoniously to her feet; she knew there was no way she could both resist them and protect Barry in her weakened state, especially in her beautiful but restrictive outfit.

Follow the script, she told herself as calmly as she could. We've just got to follow the script, and I'm pretty sure this is it.

"Hey, be careful with him!" she couldn't help yelling as one of the goons hefted Barry onto his shoulder with very little concern for the way Barry's head banged the floor.

"Shut up, Blondie," the other goon said, pushing her roughly to follow after their boss.

I swear, if one more person calls me 'Blondie'….

I hope you enjoyed it; let me know either way!
