So, I'm aware my Karry stories are less popular than that of my Beta's (CharmedMille – Karry Master) or even Speedforce's (Call Me Kara was amazing though) but I actually don't mind anymore. Read or don't read, this story will happen. Following on directly from both my previous fic, 'Super Double' (you don't need to read that, but it would help) and the Flash finale, I shall be submitting this 23-chapter story (23 episodes, 23 chapters) for you fanfictioners to read and enjoy.

Unlike my previous stories, each chapter will be a somewhat solo adventure, some with a 'monster of the week' feel, others just emotional development. True, some stories will be loosely linked (such as this chapter with the second) and some will be a continuation of a previous chapter, I intend this story to have a much more episodic feel than anything I've written before. So that's the plan. Anyway, please read, enjoy, follow, favourite and review! Thanks in advanced. I'll be making the effort to reply to those of you with accounts too.

I do not own anything from DC, the CW or even CBS (even though Supergirl is now owned by the CW).

Episode One – Kara's Intervention.

Barry sat on the steps to the West household. He'd just rejected Iris and he wasn't too sure why. He had an idea in his head of what he wanted to do, where he was going to go, but his sudden grief consumed him enough not to be able to stand up. He'd lost his mom so long ago and now his dad was gone; yes, he had his adoptive family and all his friends – back inside the house behind him actually – but he'd never at this moment felt so alone.

True, there was the doppelganger of his dad out there on Earth-3… or was it Earth-5 now? Jay might have called it Earth-3, but Barry had been to two other Earths before learning about Jay's Earth. This numbering was getting ridiculous, he really needed to talk to Cisco about what names to give these other Earths now so many were turning up. If Cisco was still working at STAR Labs after what he was about to do.

He stood, the sudden resolution of the task ahead of him laying heavy as his mind tried to fast-track to what he'd come back to: Save his mother, stop Eobard Thawne, and return to what? The real Harrison Wells alive, maybe with his own Jesse? His dad was sure to still be around, and with his mother now alive. Would Joe have sought out Francine again in this new timeline, without Barry to look after? Iris could have known her brother, her true brother, longer than in this current timeline. Yes, there were more pros to this than cons, Barry was sure.

"Harry left?!" The voice distracted Barry to the point of being a physical barrier, he collapsing as he turned on the spot with speed to the originator of the question: a blond in a black outfit.

Dressed like Alex had been when he'd said goodbye to her the first time, the clone of Kara Danvers stood a few feet away, arms crossed in indignation, her now short-cut-hair waving ever so pleasantly in the evening breeze, but there was a fierce look of anger in her eyes as she marched a few steps closer to Barry and asked atop of the previous question: "Why wasn't I informed? I could at least have said goodbye to him."

"Kara…" Barry swallowed, all previous thoughts drowned from his mind now as he looked her up and down once more, a hand flying to the back of his head to rub the nape of his neck in worry. He had nearly forgotten all about the clone in his single-minded vengeance against Zoom. "I… we… where were you?" It was a new thought, but it suddenly sparked a new well of emotions. A woman with powers like hers – super strength, laser eyes and freeze breath to say the least – could have saved his dad, could have helped him stop Zoom, would have prevented his friends locking him up for not having a clear head.

"My dad died and you… you weren't there!" He suddenly found himself shouting, pointing randomly behind himself in emotion, causing Kara to look to him in shock, obviously not expecting that. "Zoom killed my dad just to… to prove a point. You could have stopped him. We could have stopped him together!"

"Barry, I… I didn't know." Her anger at her foster dad leaving without her had lessened for the fact that Barry's real dad had left for good; the ferociousness of her features softened to a sudden well of tears herself as she moved over to Barry, whose own emotions had been held at bay since that fateful night and had suddenly come to a peak as he collapsed into her arms. "I didn't know." She repeated simply, softly and soothingly. She herself hugging Barry as best she could while supporting most of his weight.

Barry could hear movement and realised his shouting must have alerted the West household, for next thing he knew, he was being led back into Joe's house; Kara by his side, Joe on his other side, and was on the sofa long before he properly realised what had happened.

"Nice to see you again, Kara." Joe pointed out kindly as she sat next to Barry on the seat. "But maybe a phone call next time?"

"I don't have a cell," Kara replied simply, her eyes remaining on Barry as Iris joined them, perching on the coffee table.

"He's been through a lot. I thought he was doing okay…" Iris stared at Barry, who had a hand over his face now to hide the tears streaming from his eyes, the weakness he felt they shouldn't see, but didn't react to being talked about as if he wasn't there.

"Zoom killed his dad" Kara stated, somewhat bluntly, "he just told me. If I'd have known…" She looked around, taking note of Cisco, Caitlin and a boy she didn't know by the dining table, looking awkwardly at the new scene in front of them, before back to the shielded Barry. "I've been training, learning, becoming more human. Alex and Lyla have taught me a lot, but had I had known, had they told me…"

"ARGUS likes to keep their secrets." Cisco pointed out from behind her, Kara nodding silently as she locked eyes with Iris, both women concerned for the speedster now.

"They should have told me," Kara mumbled but knew Cisco was right as she looked at Barry, wondering what she could do to make him better.

Iris had never seen Barry like this, even after his mother died, even after stopping Eobard. He was still more-or-less himself when his back had been broken, even if he'd lost confidence then. He'd become a recluse after their somewhat-victory against the older speedster last year, but this time it was different, he had been involved so emotionally. He'd let the fake Jay Garrick into their lives, had trusted him with Caitlin and as a result had let Zoom into their very back pocket enough to know all of their weaknesses and exploit them in a way Eobard never thought to do, even up to his final moments.

Barry was broken.

-PowerFlash-

He hadn't argued when Joe had forced Barry to go to bed and rest – he'd exhausted himself far more than any speeding could. Emotional exhaustion was so much worse than the physical. This wasn't something Barry could outrun; this was something he had to accept.

Kara found she didn't want to leave his bedside, but with him falling asleep almost the moment his head hit the pillow, there was very little else for her to do, so found she joined the rest of the team in the living area, all with various expressions of worry on their faces. Hers joined the fray, but she couldn't keep quiet as she addressed Joe, speaking as formally as possible.

"Why did nobody call me? I honestly could have helped. I could have saved his dad and at least said goodbye to Harry before he left…" From the reactions of most of those gathered, it suddenly became very obvious that Kara had been the last person in their thoughts that fateful day, and Kara suddenly felt more deflated than before, letting off a simple "oh" as she sat resolutely on the arm of the sofa.

"It's not that we didn't think of you." Caitlin quickly interjected. "It's just we had a million other thoughts going on and you were still in training…" Caitlin stopped speaking, not really sure where she was going with this. Truthfully, there was no excuse for not calling Kara. Well, maybe herself being trapped by Zoom was an excuse for her, but she was unsure why no one else ever thought of it. When Barry was powerless and there were thousands of metas from Earth-2 rampaging the city they could have used the super powered clone even if she was still training.

"We didn't know if you would be up to facing off Jay – I mean Hunter – and Henry's death was so sudden. Zoom just took him…" Cisco's voice drifted off, he remembering just how sudden, how awful that had been. That day had started so well, too.

"I still could have done something. I hate to see Barry like this, it just reminds me of when I was created, of him being trapped in that place, so helpless." She bit her lip as silence fell over the room.

"I'm sorry, and I get the situation is dire, but who exactly are you?" The young black boy spoke up from next to Cisco, and Caitlin and Kara looked to him dumbstruck.

Joe and Iris however reacted quickly; one getting up and moving to the boy, the other clapping a hand of their forehead in realisation. "Wally. This is Kara," Joe stated simply, he being the one to move to him. "She a… friend of Barry's." That was the easiest explanation in the current situation.

"I'm a clone of a friend of Barry's," Kara corrected simply, not realizing Joe was trying to keep it simple. After all, she had long since accepted her start in life, blessing each day that was granted to her that she could simply exist. "He travelled to another Earth, as the Flash, and came into contact with that Earth's version of me, came back with a DNA sample and bumped into a meta-human who could clone others. I came from that DNA sample." She gave him a very polite smile, which he responded, if a bit confused.

"She's also an alien," Cisco pointed out, the same smile on his face as he always had when he thought of that.

"Ninety-five percent of one actually," Kara corrected to the sudden concern of Cisco and Caitlin. "I guess the five percent is linked back to Duplicate, my creator." She added the last for Wally's benefit, "but it hasn't stopped my enhanced abilities. I'm still super strong, superfast, invulnerable to practically anything, my eyes shoot laser beams and I can see with X Ray vision… yeah, the whole works." She couldn't help but grin at this herself; since training with her powers she had come to love them.

"And the freeze breath Barry admired?" Cisco asked simply.

"Yeah, that too," she leaned back on the arm of the chair as she added thoughtfully, "and the flying and enhanced hearing…" She then fell into silence.

"I can see how you would have been of great help against Zoom," Wally pointed out, almost admirably as Kara nodded to him. If he had managed to help, even a little, against the speedster, then this girl would have been a major advantage in the battle against Zoom.

"I still wouldn't have been able to save his dad, probably." Kara muttered sadly.

"I'm sorry." This was Iris. "I don't think Wells was truly thinking about you when he left." This caused Kara to glanced concerned to her. "Jesse was going to go back to Earth-2 regardless and Wells – Harry – didn't want to lose her again. He chose to go back with her. If it hadn't been so much of a rush and he had thought of you I'm sure he would have sent for you or at least done something for your benefit."

"Barry could always take you to Earth two, with my help." Cisco pointed out as he added, "I'm Vibe, yo, I can open portals to other worlds and that still sounds so weird even though I've done it a few times already."

"You're a meta?" Kara suddenly sat up, "why have you not told ARGUS?"

"I need to?" Cisco responded, worry in his voice.

"Their meta department keeps tabs on all known meta-humans, including those in the precinct and in your pipeline. Just in case, you know."

"I don't" Cisco replied suddenly bluntly, "but I assure you I won't be going all Reverb on anyone anytime soon."

"This is giving me a headache," Wally suddenly pointed out.

"Me too" Joe stated, "all this doom and gloom. I know we need to grieve over all we've lost, but this is just insane. You're all welcome to stay here tonight, I have blankets and whatnot in the linen closet, but I'm heading to bed. Hopefully we can all think more clearly in the morning. Err, Kara and Iris… could I…?" He indicated the kitchen, so he could have a private word with the pair.

Kara and Iris exchanged glances but followed regardless, Cisco and Caitlin taking their place on the sofa quickly while Wally bid his goodnights to everyone and headed upstairs himself.

Once in the kitchen, Joe kept his voice down, but the urgency was still put forth. "I won't deny I'm concerned for Barry. He wasn't acting himself earlier and I have no doubt that he would have done something stupid had you not turned up, Kara. Iris you know him, Kara you're fast enough to match him. If he gets up in the middle of the night, please make sure he doesn't do anything stupid."

"You think he wants to time travel, don't you?" Iris asked, her voice equally low.

"Possibly. Prevent Henry's death, hell maybe even break his own code of conduct and save Nora, his mother." He added that for Kara's benefit. "As much as I love the kid, neither should be accomplished, who knows what it would do to the timeline. Your dad sure as hell wouldn't agree to it, Miss Wells."

"Agreed," Kara stated simply. "I can watch over him. I don't need sleep, but if I need Iris –"

"I'm good to help," Iris stated over Kara quickly. "Barry needs all the help he can get, and to let him think straight. We need to let him grieve without doing something unexpected."

"Thank you" Joe stated fondly. "And if those two stay," he indicated Cisco and Caitlin outside, "make sure they don't put the TV on too loud this time?"

Iris laughed. "Sure."

-SuperFlash-

The morning indeed brought in a fresh perspective. Cisco and Caitlin had too stayed at Joe's – Caitlin on the sofa, Cisco on the rug – while Kara had stayed in Iris' room, although the Kryptonian clone hadn't slept. She'd found, along with her training, that she needed less sleep than a normal human; she didn't know if this was a clone thing or an alien thing, but it had proved helpful in her studies of Earth law and history. One thing was certain though: She had been able to attain a wider knowledge of her studies and take in more informative than was humanly possible. That was an alien thing, she was sure.

But despite not having slept, there was no reason for her to have stayed up. Barry had remained asleep from the moment Joe had put him to bed and only when she heard stirring, and used her X Ray vision to look through the wall, did she move with speed to Barry's side.

Joe's talk the night before had held some sentiment on Kara. If Barry did plan on travelling back, particularly to save his mother, she could cease to exist – events could unfold very differently and he may no longer have been the Flash in the new timeline. It was one of many streams of thought that had travelled around Kara's brain throughout the night, so making sure that Barry didn't act on this was tantamount.

It seemed Barry had temporarily forgotten the events of the previous night anyway, or the grief had overridden them, as when he groaned for Kara to come in after she had politely knocked on his bedroom door, did he gape at her. "Kara! I… Oh." The moment of brief forgetfulness lifted as his eyes darkened, but his smile remained, albeit weaker than when it started. "It's nice to see you. Bad dreams. Spectres of grotesque beings in black haunting me." He shuddered as he added more forcefully, "You stayed?" Looking at this Kara he remembered the other two Karas – despite being in dangerous circumstances, both had lightness to them that just didn't go out. Clone Kara definitely seemed to have inherited that lightness from whichever Kara the DNA had come from.

"I didn't want you doing something silly. Caitlin and Cisco are still here too. Seems the West household had quite the sleepover last night." She smirked as she talked.

"How do you know about sleepovers?" Barry rubbed his eyes as she he shifted position on his bed to get a better view of Kara, who remained by the door.

"Alex. I've learned a lot since we last parted over a month ago," she informed him.

"Really?" He yawned. "Sweet," he added with a stretch, and then he stopped, a thought seeming to cross his own mind before he turned to look at Kara. "And I was..."

"Was what?" She didn't know what he meant as she moved across the threshold finally, her arms folded still.

"Going to do something silly. I wanted to go back and save them, both of them." He looked down to his feet now in thought, sitting on the edge of his bed, almost ashamed at what he had nearly done.

"Your parents." It wasn't a question. Kara stated it as fact.

"I thought it would make everything right. One event could change the course of everything: Thawne wouldn't kill Harry – this world's Harry – who in turn could have had the family we knew from Earth-2; Joe may have reconciled with Iris' mum; Iris could have grown up with Wally as her brother from the start; Ronnie may not have died and he and Caitlin…" he swallowed, another death he took on his shoulders. "Eddie wouldn't have died, either." Barry paused at that. Would Eddie and Iris have been together then or would he and Iris be a couple, like on Earth-2? "Hell, we may not have opened the breach to Earth-2 which would mean no Zoom."

Kara remained silent. She wondered where Barry was going to go with this, wanting to point out that things happened for a reason, but she could almost see the cogs working in his brain, the realisation popping up like a jack-in-the-box when it reached its limit. Yes, Alex had shown her one of those too; she had taken a great pleasure in showing the alien clone the human world.

"But if I didn't breach universes in this new timeline, I would never have met Kara Danvers and in turn, wouldn't have created you." He looked up to Kara once more, a small smirk on his face. "If you hadn't turned up when you did I would have gone through with it. I don't think I could have lived with myself, even with my parents alive, to wipe the possibility of you from the world. Whatever Kara it may be; the world is better off with a Kara in it."

At this, Kara moved over to Barry, sitting on the bed next to him as she somewhat instinctively put an arm around his shoulder. She still needed to control her strength, so she let it rest around him instead as she said soothingly, "I'm glad you thought of me."

"Yeah" Barry stated. "And I'm sorry. I'm sorry that Harry left without telling you. Cisco can open breaches, maybe we could… I dunno…"

"It's fine, honestly," Kara lied. In truth when she'd found out from Lyla the events from Central City she had been devastated to know that the only other person who'd shown her affection from the moment she'd been made had left without even a second thought. She always had Alex who, despite being her superior, was almost like a sister to her, a guide in this strange world. It had been Alex who insisted Kara go and see Barry when she did, and now Kara was glad she hadn't counteracted that decision.

"Did I tell you I like your hair short? Very Cat Grant" Barry suddenly added, having stood from the bed to look around at her.

"Who?" Kara asked, having not heard the name before.

Barry smiled at the question and nearly laughed but was interrupted by Cisco's voice screaming his name. "BARRY!" A shiver ran down Barry's spine at the urgency of the cry, but before he could move, Caitlin was at the door.

"Sorry. Something… well someone… please, you need to come down, now," Caitlin's hair fluttered in the sudden breeze Barry created, speeding past her and down to the living area. Caitlin looked apologetically to Kara before adding to the girl, "If you're staying, I think you need to come down too."

In front of the bay window by the front door a man stood. He was slightly taller than Barry and of bigger build. He wore red. Particularly the jacket with the large lightning bolt going from waist to neck and the helmet he now supported as a relic to a tortured past that was tucked under one of his arms. He was looking seriously to Barry who stood frozen to the spot, the sight of his father's other Earth doppelganger still sending shivers through his entire body.

"Allen," Jay Garrick addressed Barry. "I'm afraid I'm not here on good tidings."

Barry shook his head, unsure of what he was seeing and hearing. It was bad enough that an alternative Flash went around wearing his dad's face, but to hear from those lips words so blunt and less than friendly was still strange to experience. He also didn't see Iris and Joe standing in the door to the kitchen or Caitlin and Kara moving down the stairs until petite fingers intertwined with his own and he gripped tight, Kara's own hands able to take the strength with ease.

"Jay…" Barry finally breathed, "What… what happened?"

"My earth is gone," Jay stated bluntly.

"G- Gone? What do you mean?" Barry remained shocked still.

"I left Harrison and his daughter," Kara's grip suddenly got painfully tight "on their Earth and went to return to mine, only to find it was gone. Nothing but a shell split in two. Everyone… dead."

"My vision," Cisco now moved into Barry's peripheral vision, next to Kara though, "of Earth-2 splitting in half. It happened? But to your Earth?"

"I fear I was gone too long." Despite his stoic disposition, a great sadness seemed to spread across his older features, "I have no home and I don't know why. I was hoping as a fellow speedster you could help me understand what happened."

"But we stopped Zoom," Cisco pointed out angrily, "he had a device that would destroy all Earths, Barry stopped him and the device –" In his surprise and anger, he moved forward again, his bare hand brushing Kara's free one and, in that second, he stopped. Everyone else in the room though, thought he had finished his sentence, indeed Jay continued to talk, but Kara no longer heard the words, she staring at Cisco in shock.

Cisco seemed frozen, paralysed, as he watched something Kara could not see, and only when she tugged on Barry's hand, still holding hers, did Barry look to her to see Cisco in his unfazed expression.

Everyone in the room seemed to follow Barry's gaze now as Cisco suddenly blinked, coming back to life, and his eyes found Kara. He swallowed.

"What did you see? Was it another Earth being destroyed?" Barry asked worriedly.

"N- No… It's Jesse. She's…" his eyes flickered from Kara, to Barry and then to Joe, "she's dying!"
