3.1K words, and only one of the other teams was introduced. Wow, that's a lot. O.o

Also, a little friendly reminder - this is after Flash episode 3x17 "Duet," so not much time has passed for Team Flash. Arrow is a bit ahead of schedule - this is post 5x21 "Honor Thy Fathers" with some dialogue from 5x22 "Missing." Chase hasn't attempted his "master plan" yet, so Rene and Dinah are still around for now.

Anyway, Team Flash and Team Arrow have arrived! Enjoy, guys!

Barry smiled smugly as he watched his friends fawn over Iris's new ring. Finally, after everything that had happened in the musical world (Music Meister, really?), he and Iris were engaged . . . again. And hopefully, they were going to stay that way. There was still Savitar to deal with, but they would handle him, just like every villain they had met before.

"Hey, dude," Cisco spun to face Barry. "I'm still your best man, right?"

"Did you ever doubt?" Barry grinned.

Cisco whooped, making Caitlin smile. "Congratulations again, guys," she told them.

"Mazel tov," HR nodded. "When's the date, BA?"

"Uh," Barry winced. "Let's deal with Savitar first, OK?"

"Right," HR nodded rapidly, rapping one of his drumsticks on top of his head. "Savitar first, wedding later."

Rapid beeping came from the console, and Cisco took one look and groaned. "Come on!" he complained, standing up and heading out of the cortex. "Can one day go by and we don't get a breacher? One day!"

"Again?" Barry asked in surprise, following after his friend.

"Yes, again," Cisco ground out, gesturing to the breach hovering in the breach room as Caitlin, Iris, Wally, and HR entered behind them. "One day!"

A few seconds went by, and Wally frowned. "Uh, don't people usually jump out immediately?"

"Usually," Barry narrowed his eyes, preparing to run at superspeed if needed.

"Maybe this person's not hostile?" Iris suggested.

"Maybe," Cisco rubbed his hands together as Wally got into a running position, too. "Or maybe they're trying to catch us – " Out through the breach tumbled a lanky young man in black tactical gear, and Barry immediately shot up, blinking in stunned shock. "Off guard?" Cisco looked at Barry warily.

"OK, definitely not the Fortress," the brunette babbled, looking around, not seeming to notice the surprised group in front of him. "OK, just hope it's the right Earth – "

"Winn?" Barry finally sputtered, eyes wide.

He yelped and spun around, throwing his hands up in the air before brightening. "Barry!" he cheered. "Please tell me you're the Barry that I know."

"You know this guy?" Iris looked at Barry dubiously.

"Oh, my God," Barry's face split in a grin as he ran forward. "Good to see you, man!"

"Hey, you too!" Winn smiled and waved before blanching. "Oh, no."

"Oh, no?" Barry blinked, not sure if he should be worried or not.

"Kara," Winn pointed back to the breach, swallowing hard. "Mon-El's not on our side, he and his dad are trying to kill her – "

"What?!" Barry's head whipped back to the breach.

"Then I'll make sure he doesn't get through!" Cisco grabbed his goggles and slipped them on, running through the breach.

"Oh, God," Winn swallowed, running a hand through his hair. "I should not be surprised they followed us."

"You said Mon-El's trying to kill her?" Iris asked in disbelief. "Why? How?"

"Uh . . . " Winn looked nervously at Barry. "It's a long st – "

He was interrupted by the breach flaring, and everyone turned expectantly. However, Iris screamed and Caitlin, Wally, and Winn all started shouting at once when an auburn-haired woman in the same black tactical gear as Winn staggered out, just barely supporting a disoriented Kara in full Supergirl gear, her abdomen soaked in blood. Barry saw her pitch forward, and before the woman could catch her, Barry sped forward, catching his friend in his arms. "Kara?" he asked nervously, barely hearing Cisco jump out of the breach and close it behind him. "Kara!"

He saw her look at him in recognition before her head lolled back and her eyes closed. Barry looked back down at the steadily growing red stain on her suit, and he sped out of the breaching room, right to the medbay, carefully laying Kara down on one of the beds. Wally followed a second later, depositing Caitlin, whose hair blew slightly as she was set down. "Both of you, out," she pointed for the door immediately as Cisco barreled in, the others behind him. "Let me work!"

"Sun lamps help!" Winn shouted as the two speedsters held up their hands, stepping out of the door as Caitlin pulled on a pair of latex gloves. Barry instantly sped off, and when he returned, he was holding two sun lamps, and Winn blinked. "That'll do."

"It was a Kryptonite blast to the side," the auburn-haired woman ran up, ignoring Caitlin's protests for her to stay out. "I'm her sister!" she finally snapped, and Caitlin instantly shut her mouth. "But she took a Kryptonite blade to the side an hour or so ago, it might have opened up again."

"OK," Caitlin nodded, looking at the others. "I'll make sure she doesn't have any bits of . . . er – "

"Kryptonite," the woman repeated. "Pieces of Kara's home planet. It's poisonous to her."

"Got it," Caitlin nodded, reaching out and closing the door.

The moment the door clicked, Winn collapsed in a chair nearby, Barry not that far behind him. Cisco was pale as he sat, the West siblings looking between all of them. HR got the memo to be quiet and hung back. "What happened?" Barry finally looked at Cisco.

"It was bad, man," Cisco whispered. "When I got there, Mon-El and someone else had pushed Kara to the ground. Their weapons were glowing green – I guess that was Kryptonite because Kara's skin was glowing green, too. They were ready to shoot her when I blasted Mon-El away."

"That was Lar Gand," Winn mumbled, making everyone look at him. "He's the King of Daxam, Mon-El's father.

"Why would he do this?" Iris shook her head in disbelief. "I thought he loved Kara."

"Oh, we all thought he did, too," Winn chuckled bitterly. "Nope, turns out he never did. Scared she's going to kill all the Daxamites, actually."

That got him stares from everywhere, including from HR. "Kara?" Barry repeated incredulously. "Killing?"

"Exactly," Winn nodded.

"Winn, Kara's not a killer."

"Well, didn't stop Mon-El and his family to try and kill her because they thought she would be."

Bright light came from under the door, and Cisco perked up slightly. "Looks like the sun lamps are on."

Caitlin slipped out silently, pulling off her red-stained gloves. "No Kryptonite in the wound," she told them, sighing. "She's just lot a lot of blood. Her sister's staying with her, just to make sure she'll be OK."

Everyone in the room let out a sigh of relief. "And then what?" Wally asked.

Caitlin just shrugged. "Whoa, you can't go back to your Earth if Mon-El's trying to kill Kara," Barry immediately shook his head. "No way."

"Actually, before he found us, we were planning on coming here and asking if at least Kara could stay," Winn winced. "We found . . . something that basically paints a target on her back, and she does not deserve to be looking over her shoulder for Kryptonite-wielding Daxamites while also trying to save the city. And possibly the world. Which would probably happen if it meant they got to kill her."

"No one's killing Kara," Barry assured Winn. "Not on my watch."

"Definitely not," Cisco agreed. "She helped save our world when the only person she knew was Barry. Probably about time we helped her out on her world."

Barry perked up midway through Cisco's words. "Oliver and Sara may want to know," he told Cisco.

"Yeah, and maybe they can help?" Iris suggested. "I mean, they don't know her very well, but it's like you said, she helped us without expecting anything in return."

"Yeah, and Oliver could go on ahead and kill Mon-El if no one else will," Cisco grinned uneasily.

Barry snorted loudly. "Um, hold on," Winn held up his hands. "Oliver? As in the Arrow guy Kara mentioned?"

"Actually, he goes by the Green Arrow, but yeah, same guy," Barry nodded, standing up. "OK, Cisco, get to Star City, tell Oliver what's going on. I'll get a message to the Waverider. Iris, Wally, can one of you tell Joe that I'm staying here for Kara?"

"Yeah," Iris nodded immediately, pulling out her phone.

"And, ah . . . " Winn fidgeted. "I'll just hope Kara ends up OK."

"She's strong," Caitlin patted his shoulder comfortingly. "She'll be OK."

"OK, so," Cisco rubbed his hands together as Barry moved to the console, tapping a few buttons. "Star City, and hopefully I don't get an arrow in me."

Winn laughed as Cisco jumped through the breach he created, only to stop when he realized no one else was laughing. "Wait, he wasn't serious, was he?"

"You haven't met Oliver Queen," Caitlin said dryly.

"Trust me, if you did, you'd know Cisco was completely serious," Barry nodded.

"OK," Winn winced, scratching the back of his head. "He sounds like a joy to be around."

"You know, I almost forgot what it was like to have nothing to worry about," Thea mused as she poured herself a glass of champagne.

"That's because we're usually saving the city from being destroyed by a psychopath of some sort this time of year," Dig remarked dryly.

"Yeah," Dinah nodded as she took a glass from Thea. "Is that normally what happens here? Someone tries to destroy the city?"

Oliver snorted. "Malcolm Merlyn, Slade Wilson, Ra's al Ghul, Damien Darhk . . . "

"Well, looks like we won't have that problem this year," Rene smirked.

"This is like summer break for you guys," Quentin looked around. "What are you gonna do, huh?"

"I've always wanted to see Florence," Curtis mused. "The city in Italy, not the woman or her weird machines."

"Ooo," Rene mused. "That sounds nice."

"I'm gonna teach J.J. how to fish," Dig nodded. "Two days with my son on the water? That would be heaven."

"I was thinking of the Pacific Crest Trail for a night," Felicity smiled. "Or, you know, just one night under the stars and then definitely a manicure/pedicure afterwards."

"Now that sounds like heaven," Dinah grinned.

"What about you, Oliver?" Dig asked. "I know you got city hall and all, but – "

"Yeah, it keeps me busy," Oliver nodded. "But I need to buy some socks." Dig and Rene snorted loudly, and Oliver looked around defensively when Thea and Quentin gawked at him. "Everybody has their thing! I need socks bad."

"Socks it is," Quentin shook his head, unable to keep from laughing.

"Well, at least we all get to do our things now," Curtis smiled.

"Hear hear," Thea raised her champagne glass. Oliver smiled in agreement, clinking his glass to hers and tilting his head back, drinking.

A hissing grew in volume, and suddenly above the coffee table formed a familiar swirling mass of blue and grey. Oliver choked on his drink, hastily putting it down and grabbing for the nearest knife. "Oh, are you kidding me?" Curtis complained as Dinah instinctively reached for her gun. "Are you kidding me?"

"One day!" Rene scowled, setting his drink aside. "One day we won't need to deal with crap like this!"

"Hold on," Felicity blinked, pointing at the mass. "Isn't that – ?"

Cisco jumped out of the breach, yelping when he saw he was heading right for the coffee table. He threw himself to the side, landing on one of the couches instead. His head poked up over the arm rest, and he held up his hands. "Don't shoot me with an arrow, please!"

Rene blinked. "Tech guy from Central?"

"Cisco!" Felicity cheered, then blinked. "Wait, how did he know about the party?"

"I'm interrupting a party?" Cisco looked around, getting off the couch and scratching his head. "Oh . . . that's really bad timing."

Oliver sighed, mentally preparing himself for whatever speedster he had to help Barry with this time. "So do you need help with this evil speedster Barry mentioned last time?"

"You'd do that?" Cisco brightened. Oliver opened his mouth to answer, but Cisco shook his head, holding up his hands. "No, no, Savitar's not why I'm here."

"Then why are you here?" Dig frowned.

"Uh, an alien we all thought was invincible came out of a breach at S.T.A.R. Labs, and she was bleeding, and I mean bad."

Oliver choked on air that time. "Kara?" he finally managed to ask when was able to speak again.

"Supergirl?" Thea gawked.

"As in the 'we couldn't even scratch her' Supergirl?" Dig demanded.

"Yes, that Supergirl," Cisco nodded. "And Cait is currently blasting her with sunlight to try and help her heal, but the thing is, her boyfriend tried to kill her – "

"Her boyfriend?" Felicity's jaw dropped.

"Well, her ex-boyfriend now, I'm pretty sure," Cisco winced. "Or her late boyfriend, because no one back at S.T.A.R. Labs is happy – "

"I'm not happy hearing this, and I don't even know the girl," Quentin snorted.

"All I heard is Supergirl is apparently not as invulnerable as we thought she was," Rene held up his hands.

"Enough," Oliver shook his head, walking forward. "You said sunlight is helping her heal?"

"Caitlin's got her under it right now," Cisco confirmed.

Oliver nodded. "Just bring me back when she wakes up. I'll need my gear."

"Whoa, hey!" Thea hurried past Quentin, running up. "I'm coming, too!"

"And me!" Felicity jumped right in, too. "John, too!"

"Me, too?" Dig parroted, eyes blinking rapidly.

"Guys," Oliver began.

"Hey, she helped us save the world," Felicity poked him the shoulder. "We're going."

Dig sighed, putting his champagne glass down. "Yeah, when you put it that way."

"Guess there goes the hope of summer vacation," Dinah raised an eyebrow.

"You guys, stay here," Oliver told them. "Just because Chase is out doesn't mean Star City won't have problems."

"On it, Hoss," Rene nodded.

Oliver nodded back, and as Cisco opened up a breach again, Oliver was the first to jump through, followed by Thea, Felicity, and Dig. Cisco was right behind them.

Barry finished his recording for the Legends just as another breach appeared. "Whoa!" Winn jumped up from his seat as Iris and Wally turned around. "That did not take long!"

"Oliver," Barry grinned as his friend jumped out of the breach, then groaned when he saw he was dressed up. "We interrupted something, didn't we?"

"It sounded like this was more important," Oliver shook his head, accepting the hug Barry gave him as Thea, Felicity, and Dig came out next, Cisco closing the breach behind them. "Cisco gave us the rundown. He said Kara was bleeding?"

"Yeah, man, it was bad," Barry nodded, making Oliver sigh and pinch the bridge of his nose. "Disoriented the moment she got through the breach, passed out a few seconds later."

"She lost a lot," Caitlin added. "But her sister said yellow sunlight should help her heal."

"S.T.A.R. Labs has sun lamps?" Felicity asked in surprise.

"Well," Barry held out, wincing.

"Barry," Iris sighed.

"I may have borrowed them from Mercury Labs."

"Barry!" Caitlin protested.

"Well, would you have been able to help Kara if she was outside?" Barry raised an eyebrow, gesturing up towards the sky wildly. "It's night, Cait!"

"Barry's right," Oliver nodded. "Look, if the sun lamps will be an issue, I can cover them, as long as they help Kara get better."

Caitlin sighed and nodded, and Thea bit her lip. "How's she doing?"

"We got the bleeding to stop, but she's still out," Caitlin answered. "My guess is she's just exhausted."

"It's been a long few days," Winn nodded, rubbing his temples.

"You need anything?" Caitlin asked in concern.

"Either a lot of caffeine or a really cold glass of water would help keep me up."

"Winn, we can wake you up when she's up," Barry began.

"No," Winn shook his head stubbornly. "I was the one who suggested we go to the Fortress, which is literally in the middle of the freezing cold nowhere. I'm staying up."

"It might be a long night," Caitlin warned.

Winn held out his arms. "I've got nowhere else to be." He paused. "Except Earth-38. But that's not a good idea, because no doubt Mon-El will want to gut me when I get back." He wrinkled his nose. "That's a cheery image."

"It's one I'm still adjusting to," Barry sighed.

"Guessing that's the ex-boyfriend?" Dig asked dryly.

"Oh, definitely ex," Winn nodded. "Shooting her was pretty much him saying they broke up." He blinked. "And I don't know any of you."

Oliver raised an eyebrow, but a beeping from the console made everyone turn. "Did they respond?" Cisco asked, taking his goggles off.

Barry tapped something on the console and grinned. "Sara's diverting the Waverider here right now." He blinked, then tilted his head, looking like a confused puppy. "And she's asking who in their right mind would try and kill, and I quote, 'that supper puppy?'"

Winn burst out laughing, followed shortly by Thea, Felicity, and Cisco. "Oh, that's definitely Kara," he grinned widely. "That is Kara in two words."

The door to the medbay suddenly cracked open, and Winn shot up when a bleary-eyed Alex looked out. "Hey," she whispered. "She woke up for a few seconds, mumbled a bit of nonsense, then fell back asleep. She's gonna be fine."

Barry leaned against the console in relief, Oliver visibly relaxing. "Good," Winn smiled.

Alex smiled wearily back, shutting the door behind her again. "Guess that means the Legends won't have to wait long to see Kara when they get here," Dig remarked.

"The Legends," Winn mused. "Sounds really cool. Maybe a bit egotistical, though."

"Hey, that's what I said!" Thea grinned, pointing at him.

Barry smiled, happy to see Winn interact more with his friends, then looked up as Oliver walked closer. "Mon-El doesn't sound like a human name," he said quietly.

"It's not," Barry shook his head. "He's a Daxamite, and from the sound of it, he's not the only one on Kara's Earth right now."

"Another invasion?"

"How much did Cisco tell you about why Kara's here?"

"Just that her ex tried to kill her." Barry rubbed a hand over his face, and Oliver frowned. "Barry, what is going on?"

"We don't have the full story yet," Barry confessed. "But from what we've gathered so far, Kara found out something on her Earth that has to do with the Daxamites, and it put a target on her back." Oliver closed his eyes, and Barry swallowed. "Oliver, she needs our help, and no matter what, I'm going back to Earth-38 to do what I can."

"And you won't be going alone," Oliver promised, opening his eyes. "After what she did for us, knowing only you? I want to hear the full story so I know what I'm getting into, but Rory was right – we've been a team since the Dominators, and Kara's on our team."

Barry nodded, biting his lip and looking back towards the medbay. "God, I hope she wakes up again soon."

Oliver just nodded absently, wondering what the hell he had gotten into this time. "So much for summer break."

***

Barry has entered protective brother mode, methinks, and Oliver has just entered protective mode. And Sara hasn't even seen Kara and is wondering what the hell's going on. XD

The Legends come into the picture next chapter, and Kara may wake up for sure!
