Oh, boy. Here comes a whammy of a midseason finale. I was super impressed with this one, even with that ending. Hope I do this episode justice!

Mon-El and Imra share a bit about the future, and it gets crowded at Casa de Danvers . . . like, very crowded. Extremely crowded. Also, if you haven't noticed, the cast list got updated . . . just so you know. ;)

Enjoy the first part of "Reign!"

Then 

When Sam woke in the morning, she gasped and shot upright, finding herself tangled in her sheets. The last thing she remembered in her dream was searing red beams of light . . .

"Mom?" Ruby ran into the room, eyes wide.

Sam panted, looking up at her daughter. "Yeah," she swallowed, holding her forehead.

"I heard you scream," she said worriedly.

"I'm sorry," Sam sighed, closing her eyes. "Sorry, I had a bad dream."

"I thought you'd wake me up when you got back from your trip," Ruby told her.

Sam frowned, looking up at her. "What trip?"

"Where you went yesterday," Ruby answered.

"I didn't go on a trip, Ruby," Sam shook her head. "I'm here."

"You said you were going somewhere," Ruby insisted. "To get answers. That something wonderful was gonna happen."

"I said that?" Sam asked in confusion. When Ruby nodded, Sam sighed. "I don't know what . . . " She shook her head. "I'm tired. I've just been so tired. Come here," she held out her arms, and Ruby crawled onto the bed to hug her. "Hi. Hi."

"Hi," Ruby smiled, curling into her.

"What time is it?"

"Eleven." Sam blinked, surprised, turning to see her clock. "Yeah, you slept in."

"It can't be eleven," Sam looked at Ruby, completely serious. "Because it's pancake o' clock!" Ruby giggled as Sam tossed the covers off, standing up. "What do you want, chocolate chip or banana?"

"Both!" Ruby shouted, running after her.

Now

5 Days Before Christmas

"It's a long story," Mon-El looked around the table.

"Well, seven years is a long time," Kara pointed out.

Mon-El conceded the point with a nod. "Strange as it may sound, the 31st century is actually not that different from today."

"What, better smartphones?" Winn asked curiously.

Imra blinked in confusion. "What's a phone?"

"'What's a phone?'" Winn repeated, grinning widely. "Oh, the future's awesome!"

"Well, technology has developed beyond imagining," Mon-El nodded. "But, at the end of the day, it's still in service of communicating with each other, and entertaining each other . . . and also killing each other. In this day, or in a thousand years, conflict is constant, but so is strength."

"And that's where we come in," Imra nodded.

"So what are you?" Alex tilted her head. "Soldiers?"

"The governments were overwhelmed by violence, by chaos," Imra answered. "Mon-El organized us, and we banded together to help Earth's leaders keep the peace, at home and in the stars. We call ourselves the Legion. And . . . " She smiled shyly at Kara. "We exist because of you."

Kara did a double take. "Because of me?" she repeated, pointing at herself.

Imra nodded in confirmation. "You inspired me," Mon-El nodded. "So, when I founded the Legion, I chose to use you as an example of what we could be, of what we aspire to be."

"When I learned about your life and work and your compassionate fight for justice and your devotion to protecting others, everything just crystallized," Imra smiled. "Your example gave my life purpose. I can't express how much it means for me to meet you in person."

Had Kara been meeting her ex-boyfriend's wife over four months ago, she would have been uncomfortable with the words. Now, she just gave a small smile and nodded back. "Thank you."

Alex smiled, patting Kara on the shoulder. She was proud of the steps Kara had taken to adjust to having Mon-El back in her life, even if it was just back at the D.E.O. She still tried to avoid him, and Imra at times, but she was slowly starting to relax. Of course, things had gotten more tense since Team Arrow had split, but at least she wasn't void of emotions around the two aliens from the future.

"So," Winn smiled. "A legion of superheroes. Ha!"

"Sounds formidable," J'onn remarked.

"Well, not nearly as formidable as another group from the past," Mon-El shook his head.

"Another group?" Alex blinked, surprised.

"Yes," Mon-El nodded. "I can't say much, because it clearly hasn't happened yet, but there was another . . . I wouldn't call it a legion."

"It wasn't known as a legion, at least," Imra shook her head.

"But it was composed of several heroes," Mon-El nodded. "Not all of them alien. In fact, most of them weren't aliens at all."

"Huh," Winn mused thoughtfully. "Sounds like Earth-X."

"Let's not go there," Kara winced.

"Sorry."

"But you said not nearly as formidable?" Alex turned back to them.

"No," Mon-El sighed. "The future has some bad things happening."

"Yeah," Imra agreed. "The darkness is spreading."

"What's that?" Kara asked in concern. "What do you mean?"

"Well, my team and I were on a mission," Mon-El began. "And, uh . . . we got into some trouble. Our ship got knocked into one of those disruptions."

"A wormhole?" J'onn asked.

"Yes," Mon-El confirmed.

"We crash landed back on Earth twelve thousand years ago," Imra explained.

"So you traveled back in time by accident?" Alex clarified.

"Which is exactly why we couldn't just go home," Mon-El nodded. "So we went into cryo-sleep and set the ship to wake us up when we returned to the 31st century. But then the torpedo hit the ship, and damaged the ship, and that's when I woke up. But do you think we can fix it?" he looked around. "Can you help us get home?"

"We'll do everything in our power to help," J'onn nodded. "But for now, settle in."

"You might be here for a while," Alex nodded.

Mon-El nodded back, and the three D.E.O. members walked off. Kara fidgeted slightly, playing with the ring on her finger, then Imra smiled at her. "If anyone can help us, it's you."

Kara blushed slightly at that. "Thanks," she nodded, then cleared her throat. "Uh, everyone's coming over to my apartment for a holiday party tonight. You guys are welcome to join, if you like."

Imra's eyes widened in surprise, but Mon-El cleared his throat. "Thanks. We, uh . . . we need to work on the repairs."

"Yeah, that's fine," Kara nodded quickly, aware of Alex and Winn looking over. "That's – yeah."

She left to join them, blowing out her breath. "Just a holiday party?" Alex asked in amusement.

"It would have been slightly more awkward if I said it was a more holiday slash lowkey engagement party," Kara muttered.

"I'm guessing lowkey means not being the center of attention as the mayor's fiancée," Winn snickered.

"Shut up," Kara sighed, then pulled out her phone when it beeped. She opened the text she received, and her eyes lit up when she saw it: All RSVP'd yes. "Yes," she fist pumped slightly.

"What?" Alex frowned.

"RSVPs came in," Kara grinned, looking up. "Get your tech brain in gear and your badass mission stories ready. It's going to be a crowded night."

***

"Now this is a holiday party," Thea grinned as she and Winn brought out the champagne.

"Is the place gonna be big enough?" Quentin asked, looking around Kara's admittedly large apartment.

"Well, it handled the last party just fine," Alex shrugged as she and William put the last few ornaments on Kara's tree, Oliver and James placing present underneath.

"Yeah, except the last party didn't have people that could clear the entire appetizers table," Dig pointed out.

"Or all the booze," James added as Lena and Malcolm arranged the alcohol bottles on the counter.

"What?" J'onn blinked.

Everyone who had been at the rehearsal dinner all either said "Mick" or "Rory" at the same time. "Yeah, that was entertaining," James rolled his eyes.

"Ohhhh, that smells good," Winn inhaled deeply as Kara pulled the last tray of ham out of the oven.

"Thanks," Kara smiled. "And the cookies?"

"Done," Felicity gave two thumbs up, stepping away from the sugar cookies.

"OK," Kara rubbed her hands together. "Now I just need to think of what to tell Sam and Ruby when they get here and find out – "

"Everyone in this room has some connection to vigilantism?" Slade raised an eyebrow.

"Exactly."

"Have fun," Laurel snickered.

There was a rapid knock on the door, and Kara cheated by lowering her glasses to see who was on the other side. "Hey!" Alex pointed at her. "Cheater!"

Kara just grinned and raced to the door. As soon as she opened it, Iris pointed at her. "Let me see!"

Kara just squealed and held up her left hand, revealing her engagement ring. Iris mimicked the squeal, hugging her tightly. "And here we all thought – " Barry began.

"We were gonna elope?" Oliver rolled his eyes, but he was grinning as he walked over to say hello. "We've been getting that a lot."

"Congrats, man," Barry grinned, giving him a hug.

"Thanks, Barry."

"Yeah, congrats," Cisco agreed as he, Caitlin, and Harry followed Barry and Iris into the room. "Saw the security footage."

"You hacked the proposal?" Oliver blinked, surprised.

"Only after your sister completely fangirled when she texted Iris," Harry snorted.

"Why does that not surprise me?" Malcolm laughed.

"Hey, I was excited, OK?" Thea defended herself.

"Suddenly I'm glad I wasn't on the receiving end," a familiar voice said, and Kara brightened when Sara sauntered through the door, her team behind her. "That must have gone on for hours."

"Seemed like it," Harry shrugged.

"Congratulations, you two," Sara smiled, holding out her arms. "Bring it in."

"Thanks, Sara," Oliver smiled, hugging the assassin.

"Ooo, new Earth," Ray looked around curiously. "It's nice here."

"Thanks Ray!" Kara beamed, hugging him after she hugged Sara.

"How's retirement, Professor?" Lena asked, walking over.

"Quite well, Lena," Stein smiled, giving her a hug. "But my work with Firestorm is still not finished."

"Nope, got the best mentor ever," Jax grinned.

"OK, it is a bit crowded," James frowned, looking around.

"Hey, the more the merrier," Nate smirked.

"Keep telling yourself that, Pretty," Mick grunted.

Slade snorted into his glass, making Malcolm laugh. "Well, guys, welcome to Earth-38," Kara grinned, holding out her arms. "And happy holidays!"

"Let's party!" Thea whooped.

***

"Wow," Lily blinked as Kara finished with the eggnog. "That is a lot of alcohol."

"Oh, yes," Kara nodded.

"Can't be as much as Grandma Esther's," Barry denied.

Curious, Iris took a cautious drink, then started coughing. "Wow," she covered her mouth as Kara and Alex laughed. "That's . . . wow."

"Exactly what I said," Lily nodded.

"OK, guys!" Kara called. "Come and get your eggnog!"

"Highly potent, intoxicating deliciousness," Alex confirmed.

"I heard intoxicating," Sara walked over with a wide grin.

"That would be Sara Lance," Oliver rolled his eyes.

"Just keep it away from Mick, he'll take it all," Sara smirked.

"Hey, where's the rest of the team?" Barry looked around.

Oliver tensed. "Let's not go there."

"Did something happen?" Sara asked in concern.

"Oh, something happened," Kara said darkly. "Rene outed Oliver, that's what happened."

"What?" Sara did a double take.

"You're kidding!" Barry's eyes widened.

"Because we would lie about the prosecution's secret weapon in my case," Oliver gave him a look.

"Man, that sucks," Barry sighed.

"Just a bit," Oliver sighed.

"OK, we don't need Rene or wherever Dinah and Curtis are," Sara told them firmly. "We are here to have a good time, and that's what we're going to do."

"Agreed," Kara nodded. "And thank you guys for coming."

"Of course," Barry smiled. "Like we would miss this."

***

"Whoa," Nate smacked his lips as he, Ray, and Amaya finished their first bit of eggnog. "That's got some alcohol in it."

"Danvers' famous eggnog," James chuckled in amusement. "What do you think?"

"I think Mick might drink it all," Amaya answered, making a face.

"I kind of want more," Nate turned back to look.

"So, any horrible things happen to the timeline?" Caitlin asked.

"Why do you assume something horrible happened?" Ray smiled nervously.

"Christmas became Beebo Day," Zari deadpanned as she walked up, already on her third sugar cookie.

Laurel choked on her wine. "Beebo Day?" Quentin repeated incredulously as Malcolm clapped Laurel on the back, the metahuman still coughing. "As in that stupid blue doll that really likes cuddles?"

"Yep," Nate nodded. "That Beebo."

"Then it was Odin Day," Zari continued. "And then Sara went on a date that involved exorcising someone. Meanwhile, some of us dueled the Wicked Witch of the Water Totem, Leo went back to Earth-X, and when we came to let Jax and Lily spend time with her dad, we found out Mr. and Ms. Perfect over there got engaged and invited us to the party."

She got several stares. "Actually, that's a pretty accurate summary," Ray admitted. "Nice one, Z."

"I'm sorry, I'm still trying to wrap my head around Beebo Day," Caitlin shook her head.

"Yeah," Nate nodded. "Welcome to our lives."

"God, when did this become our lives?" Dig grumbled.

"Still blaming Barry?" Caitlin raised an eyebrow.

"Until Barry, the strangest thing I ever saw was mirakuru." He paused, then closed his eyes. "No offense, Slade."

"None taken," Slade smirked from where he was behind the man.

***

Lena shook her head as Mick went for yet another beer, then smiled politely when Harry walked up. "Figured you'd want the scotch," he held out a glass.

"Whatever gave you that idea?" she raised an eyebrow.

"Because you've got a look on your face saying you need some of the good stuff," Harry answered, leaning against the wall. "And since I'm guessing you paid for all of the expensive alcohol in the room, it's probably good stuff."

"Accurate," Lena acknowledged, tipping her glass his way and taking a sip. "What makes you think I need it?"

"Because you look like you need a drink," Harry shrugged. "So what happened?"

Lena sighed. "Well, I'm keeping in mind that, in a way, it's my mother's fault that Oliver and Kara got together in the first place."

"Right, Project Cadmus," Harry nodded.

"Yeah, and she was my mother, so that stings just a bit."

"You were adopted, though."

"She was a Luthor, as am I," Lena said bitterly. "And did you hear about Project Cadmus on Earth-X?"

"Of course they had one there," Harry rolled his eyes. "Let me guess. Your mother did something to Overgirl, too?"

"No," Lena shook her head. "It was me."

Harry raised an eyebrow. "You led Project Cadmus on Earth-X?"

"Yeah," Lena nodded. "On Earth-X, I had a part in getting my Nazi best friend killed."

"But she wasn't you."

"She probably looked like me."

"Well, Eobard Thawne looked like me, too," Harry pointed out. "Had my face and everything. Took it after he killed Barry's mother, wore it when the particle accelerator went off. Had it when he became an SS general, had it when he tried to cut Danvers open, had it when he nearly put a hand through Smoak's heart. He still wasn't me, though. Just like Earth-X Lena Luthor isn't you."

Lena looked long and hard at Harry before chuckling. "Congratulations, Dr. Wells. You managed to cheer me up."

"Well, you don't seem the type to be a Grinch," Harry shrugged, holding out his glass. "Happy holidays."

"Amen, hallelujah," Lena smiled, clinking her glass against his.

***

"For real?" Cisco groaned.

"Seriously?" Felicity asked at the same time.

"Dude, I do not understand your obsession," Winn nodded in agreement.

"It is the greatest Christmas song of all time!" J'onn protested.

"It is a good one," Jax admitted.

"Yeah, but four times already?" Cisco gave him a look. "For real?"

"Hey, none of us complained at the party on the Waverider!"

"If my father learns nothing else this holiday season, he will learn about Hall and Oates," J'onn scowled. "Put it on."

Winn sighed, then tapped the song on his tablet. As "Jingle Bell Rock" started up again, groans came from everywhere around the apartment. "Again?" William complained.

"Seriously?" Mick glared.

"Dude, come on!" James scowled.

"J'onn's fault," Felicity pointed at him.

"Yeah, take it up with Papa Bear," Winn nodded.

J'onn just laughed, walking over to where M'yrnn was cradling a mug in his hands. "J'onn, I do not know why you introduced me to coffee first," he smiled. "This brown water is vastly superior."

"Ah, the wonders of hot cocoa," Stein smiled. "It is indeed a treat."

"Yeah, I don't take advantage of hot cocoa enough," J'onn agreed.

"I enjoy Christmas," M'yrnn decided as Lily walked over to join them. "What a wonderful way to close your year. Paying homage to an evergreen creature."

"What?" Lily blinked, only for Stein to shake his head.

"It so reminds me of Life Day," M'yrnn sighed.

"Life Day?" Lily repeated.

"Excuse me," Winn poked his head in, followed by the three others. "Hi. Life Day? As in the Star Wars Holiday Special? It was on CBS." M'yrnn just raised an eyebrow. "Princess Leia, like, sang a song?" He threw a hand up in the air. "You have no idea what I'm talking about."

"Do you even know what Star Wars is?" Felicity asked curiously.

"Do you know what Star Wars is?" Cisco asked J'onn.

"Excuse me?" J'onn scowled, offended. "The Empire Strikes Back is the best movie sequel of all time."

"Man," Cisco grinned. "Respect!"

"I just love you more and more each day," Winn grinned as well.

M'yrnn just looked confused. "What's a sequel?"

That even made the Steins and Jax look at him incredulously.

***

"You know, it's good to not be at a party where I'm getting hounded by politicians," Oliver grimaced.

"Nope," Kara shook her head. "It doesn't suck."

"Definitely not," Alex agreed. "And you were right about selling this as a holiday party, not an engagement one."

"Hmm?" Barry blinked. "I thought this was both."

"Yeah, well," Kara grimaced. "That would have been awkward to tell my ex . . . who is married."

"Any trouble?" Oliver looked between Kara and Alex.

"No, no trouble," Kara shook her head. "It's been getting better. Everything that happened when we found their ship was just . . . way too overwhelming. I still would have been upset with him – "

"Considering he didn't tell you for a day he was married," Alex chimed in.

"He didn't do what now?" Sara's eyebrows shot up.

"Yeah, that happened."

"But," Kara gave her sister a look, "it doesn't mean I need to act like . . . well, like Overgirl."

"Fair enough," Alex nodded.

"What about you, Danvers?" Sara tilted her head. "You doing OK?"

"Well," Alex blew out her breath. "Christmas without Maggie . . . that's not my favorite thing, but I am not wallowing."

"Good for you," Sara smiled.

There was a knock on the door, and Kara grinned. "That'll be the last of the guests!"

"Guess that means superhero talk is over," Barry remarked.

"I'll get it," Alex smiled, walking towards the door.

"Hey, William!" Oliver turned around, and his son poked his head up over the couch where he was chatting with Thea. "I think the Arias ladies just arrived!"

"They did?" William brightened.

Alex opened the door and smiled when she saw Ruby standing there, bundled up in a wool coat and earmuffs. "Hey," she smiled, then frowned. "Is everything OK? Where's your mom?"

"Sorry!" Sam shouted, and she ran down the hall, panting, arms full of gifts and bags. "I'm late, I know. It's been a really long day, but I got the cookies."

"No worries," Alex chuckled, holding the door wide open. "Come in."

"Oh, hey," Nate left his glass on the counter, hurrying over. "Let me help."

"Thanks," Sam smiled in relief, then paused. "Wow, there are a lot of people here."

"This was the date that worked," Kara smiled sheepishly. "Sorry, Sam."

"It's fine," Sam shook her head. "Good to see a bunch of people care. Sam Arias," she added to Nate.

"Nate Heywood," he smiled, taking the presents from her. "Nice to meet you."

"Anyway," Sam turned around. "Christmas shopping, conference call with some very unpleasant men who were yelling at me in German – "

"I hate Krauts," Mick grumbled.

Amaya elbowed him in the ribs in reply. " – and then Ruby told me about the cookies I'd forgot, the Italian bakery that I really liked, it was closed, so, you know . . . " She held up the grocery store cookies. "You get these."

"OK," Alex laughed as Sam set down the cookies. "Sounds like somebody needs to take a break, and maybe have a drink or two."

"Yeah," Sam sighed in relief.

"Want some good stuff?" Laurel asked, walking over.

"Yeah," Sam laughed. "Thanks."

"Hey, Ruby," William waved.

"Hey," Ruby waved back.

Alex put a hand on Ruby's shoulder and leaned down conspiratorially. "Did I ever tell you that I work with Supergirl sometimes?"

Ruby perked up. "OK, I have four questions."

It made Iris giggle as Alex led her over to the couch, where Jax and the Steins joined them. "So," Sam pushed her hair behind her ear nervously as Kara and Oliver walked over. "First off, congratulations. Again."

"Thank you," Kara smiled, giving her friend a hug.

"And second," Sam bit her lip. "I know no one else."

"Well," Kara held out a hand to Barry. "Barry is the one who introduced Oliver and I to each other."

The speedster mocked a bow. "You're welcome."

That got a laugh from the businesswoman, who started to relax. "Sam Arias, meet Barry Allen," Oliver rolled his eyes. "The annoying little brother I didn't know I had."

"Thanks, Ollie," Barry rolled his eyes, but smiled as he shook Sam's hand. "Nice to meet you."

"And this is Sara Lance," Kara gestured to the blonde time traveler. "If anyone here seems to be a misfit, they're with her."

"What can I say?" Sara smiled charmingly. "We're all wonderfully screwed up in some way."

"Feeling the love, Sara," Nate snorted. "Really feeling the love."

"You get used to them," Kara giggled.

***

"OK," Ruby shifted excitedly. "One: has Supergirl ever flown you anywhere? And two, if so, how was it? And three – "

"Yes," Alex laughed. "Yes, yes, she has flown me. Several times. And actually," she grinned, "last year, she caught me when I jumped out of a skyscraper during a shootout."

"During a shootout?" Stein's eyes widened.

"Awesome!" William grinned.

"OK, I have more questions," Ruby grinned eagerly.

"Me, too," Jax admitted. "Girl, you really are a badass."

***

"Hey," Lena walked up to join Kara and Sam.

"Hey," Sam smiled back.

"Are you OK?" Lena asked in concern. "I mean, you look a little pale."

"Yeah, I'm fine," Sam nodded, pouring herself a glass of scotch. "I'm just tired. Not enough hours, I guess."

"Yeah, I get that," Lena said sympathetically.

Peals of laughter came from over by the Christmas tree, and the trio looked over to see Cisco and Harry were in the middle of an argument, with Winn, James, and Felicity laughing hard. Lena smiled slightly, shaking her head, and Kara grinned. "What, you wanna get over there and join in?"

"Ah, no thank you," Lena shook her head, a slight blush in her cheeks.

"OK," Sam looked at Kara. "Which one is it?"

"Kara, I swear to God," Lena began.

"Oh, you know, just another genius CEO," Kara smirked. "She needs someone as brilliant as her."

"Of course," Sam nodded in agreement.

"No," Lena violently shook her head, but she was still blushing slightly. "That is never gonna happen."

"I would love to see you tell Winn that," Kara grinned.

"Pink cheeks," Sam pointed. "That means something."

"OK, I'm gonna have to kill both of you, all right?" Lena raised an eyebrow. "But then I wouldn't have either of my best friends, so that wouldn't work. So, I'm just gonna have some more scotch."

"Which Harry got for you," Kara mumbled into her glass.

Lena choked, coughing, then glared at her. "Kara Danvers!"

Sam laughed, and Kara smiled. "You know, some parts of this year have been really tough for me, but I did get some really great things out of it."

"A fiancé," Sam grinned.

"Oh, that's the best thing I got for sure," Kara nodded in agreement. "I got some overprotective brothers and another sister . . . and I got the two of you guys."

"Aw," Sam smiled.

"I am not wearing waterproof mascara," Lena warned Kara.

"Well, I gained several things this year," Kara smiled. "Oliver, Slade, Malcolm, Laurel, everyone from Star City, and I've always had my sister, but I've never had anyone like the two of you."

Sam sniffed. "OK, now you're gonna make me cry."

"Oh, no!" Kara giggled.

Lena smiled fondly. "I am very grateful for both of you."

"Me, too," Sam nodded in agreement, reaching for Kara. "I love you guys."

Kara smiled, hugging her back. "Love you, too, Sam."

A clinging of metal on glass got their attention. "OK, time for me to gloat!" Barry called.

"Oh, God," Oliver rolled his eyes as everyone laughed.

Kara bounded over, beaming up at him, and Oliver smiled, wrapping his arm around her waist as everyone else circled around. "So, I had two very different experiences when I first met each of them," Barry looked around. "Oliver completely terrified me, and I thought Kara was absolutely adorable."

"That's them in a nutshell," Sara grinned.

"Thanks, Sara," Oliver huffed as Kara blushed.

"They didn't get along when they first met, believe it or not," Barry added to Sam and Ruby. "They couldn't be more different. And to be completely cheesy," he turned to his friends. "It looks like opposites attracted." Kara giggled, and Oliver smiled as Barry continued. "I don't know how I was so oblivious to what was right in front of me, but you two care so much about the people you love, I would call it unmatched. It's fitting that you found each other. You have been through so much, whether it was in Central City or Star City or here. You have been through hell for each other, and you have come out stronger together." Kara smiled warmly at the words of the House of El, feeling tears in her eyes, and Barry smiled softly at her. "You two deserve each other. You deserve to have your lives happy, and full. And if I know the two of you, because I think I do, that's absolutely going to happen." He raised his glass to them, smiling widely. "To Oliver and Kara."

"To Oliver and Kara!" everyone else cheered.

Oliver kissed Kara, making Sara wolf whistle, earning her a smack on the back of the head from both Laurel and Alex. As the blonde assassin whipped around to start complaining, Barry walked over to his friends. "And I promise I have said nothing to the FBI," he told Oliver cheekily.

"Thank you, Barry," Oliver smiled, touched.

"You're absolutely welcome," Barry grinned, hugging him.

"Thank you so much," Kara hugged him as well.

"Kara." She tensed slightly and turned around to see J'onn walk up, a concerned look on his face. "I really hate doing this again . . . but I just had a call. We gotta go."

All three heroes groaned. "OK," Kara nodded, sighing.

"I'm really sorry, but it sounds important," J'onn looked between Kara and Oliver apologetically.

"It's fine," Oliver shook his head, pursing his lips. "It's part of our job."

Kara paused before she followed J'onn, then hurried over to where the Legends were speaking. "Hey, Ray," she tapped him on the shoulder. "Can I borrow you for a moment?"

"Yeah, sure," he nodded.

"OK," Kara turned around, then hurried over to the couch. "Hey, Professor Stein, can I borrow Jax and Lily?"

"Well, of course," Stein blinked. "As long as they're all right with it."

"Yeah," Lily nodded.

"Sure," Jax stood up with her.

"What's up?" Ray asked.

Kara looked between them. "Any of you want to be the first newbies here to see National City?"

***

"I'm sorry, Supergirl," Vasquez told Kara apologetically as Kara and J'onn walked up to the D.E.O. agents, Ray suited up as the Atom and Jax and Lily merged as Firestorm behind them. "I know tonight was a big night."

"What happened?" Kara asked.

"Looks like someone took a flamethrower to large swaths of the property," Vasquez answered.

"It wasn't us," Jax held up his hands.

"Any chance it was a brush fire?" J'onn asked.

"I don't think so," Vasquez shook her head, leading them further out.

"But why call us for arson after the fact?" Kara asked, looking around. "The fire's already out."

Vasquez sighed. "There's something you should see."

"Where?"

Vasquez just pointed up. "Bird's-eye view."

Kara looked between Ray and Jax. "Shall we?"

"After you," Ray nodded.

Kara leapt into the sky, Ray flying after her, Jax propelling himself up. They flew high above the ground and turned to see what happened to the field.

"What the hell?" Jax's eyes widened.

"What the hell is that?" Lily asked in Jax's head.

Kara swallowed, looking down upon the diamond shield burned into the field, a skull-like shape in the center of it. The shape was just like the crest of House El on Kara's suit. "Kara?" Ray asked quietly. "What does it mean?"

Kara shook her head, stunned. "I don't know."

***

Because what better way to have the Legends see Earth-38 than to have another engagement party? Hopefully I've written everyone correctly!

And I hope you're enjoying, because the heroes are gonna stick around for this episode, and some for the next one. Next part should (hopefully) be done tomorrow!
