There's so little of "Reversal" in here, it just gets an honorable mention in the description. XD Not my favorite episode of the season - might be my least favorite so far, actually - so I didn't do much with it here. "Midvale," on the other hand, I got quite a bit in.

So, here's "Midvale!"

***

Kara drove J'onn's car through the mountains, rarely passing other cars on the highway. She kept glancing over at Alex from time to time, but her sister wasn't speaking a word, instead opting to watch the scenery change.

When Kara saw the trees coming up, she finally managed some kind of a smile. "Welcome home," she said.

Alex just watched the sign for Midvale pass as Kara drove on.

***

Eliza was waiting for them when Kara pulled into the long driveway. Alex stepped out of the car, and Eliza smiled sympathetically, giving her a hug when she walked up. "Hey, honey," she whispered.

Alex didn't say a word, instead heading right into the house. Kara took their bags, locking the car behind her as she walked up to Eliza. She hugged her adoptive mother, happy to be home, then followed Alex inside.

***

Kara curled up on the porch outside, staring into the dark sky, then pulled out her phone and tapped out a message.

In Midvale with Alex. Don't know how long we'll be here. Call if it's an emergency.

It only took a few seconds for Oliver to respond. Take whatever time you both need. Call if you need anything.

Kara smiled fondly, putting her phone back in her lap, then heard Eliza speak from behind her. "You still out here?"

"Yeah," Kara confirmed.

"I made coffee in case this turns into a teary all-nighter," Eliza smiled, walking to sit next to her, handing her a mug of coffee.

"You don't have to stay up," Kara told her.

"Well, this is in the mom fine print," Eliza shrugged. "When your child's in agony, you show up regardless the hour."

Kara couldn't help but chuckle, remembering when Oliver and Slade had said something along those lines about a month ago. "I figured it would be nice to get her away from everything for a couple of days."

"This is going to be hard no matter what," Eliza told her. "But at least here she can lean into it. Better than letting her pretend she's fine."

Kara blinked, looking at her. "You're worried about me?"

"I think I worry about you more than Alex," Eliza admitted. "Losing Maggie is going to be excruciating, but at least Alex didn't close herself off. And I know you have Oliver now, but I still can't help but worry."

"I'm not doing that anymore," Kara shook her head.

"I know," Eliza nodded. "You have the most wide open heart in the world for other people. But when you felt weak, you punished yourself for it. You've had an awful year – "

"And Oliver has helped me feel a lot better," Kara told her. "I promise. I had my opportunity to be a mess, but I told myself too many people depend on me."

"That is a great excuse," Eliza gave her a look.

Kara snorted. "I accepted the fact that I'm not human, and that if I was going to do the things I have to do, I was going to walk away from certain vulnerabilities."

"You've thought a lot about this," Eliza noted.

"Yeah, it was a long time coming," Kara nodded. "Then Cadmus happened, and I didn't have Mon-El to lean on. But I had Oliver. And in a way, I think that's what made me better. Oliver has had even rougher years than I have had, and sometimes, he pushes those he cares about away as well. He knew what I was going through, and he helped me through it." She sighed, looking down into her coffee. "I'm happy with him," she confessed, smiling fondly. "I'm really happy with him."

Eliza tilted her head. "You certainly seem like you are," she noted, smiling when Kara blushed and tried to hide it by taking a drink of coffee. "Even though you live on different Earths? You're alien, he's human? You think this will work in the long run?"

"I wouldn't give him up for anything," Kara looked at her. "I know I shut myself down after Mon-El, but at least I tried to live my life. Now that I've had this with Oliver . . . " She shook her head. "I can't see myself living without him."

"Till death do you part, hmm?" Eliza raised an eyebrow.

Kara blushed redder again, but her simple nodding made Eliza smile more.

***

Kara walked into their old bedroom, seeing Alex reclining on her bed, still drinking alcohol. "Brought you this," Kara held up a mug of coffee. "You could make it Irish."

"What's the point of all this?" Alex asked blankly.

Kara sighed, sitting down at the end of Alex's bed. "We need to sleep," she answered. "We always slept well here."

"So we'll stay for, like, three days, and Mom will cook tons of food, and I'll gain, like, five pounds, and then walk back into an empty apartment?" Alex asked bitterly, raising her glass to drink again.

Kara bit her lip, looking down. "Do you want to talk about it?" she asked. "It might help."

Alex looked at her incredulously, then scoffed. "You don't get to do that."

"What?" Kara frowned.

"You don't get to shut down for months after Mon-El goes without talking to anyone, then these unknowns from another universe jump over, and suddenly you're right as rain, and then you sit here and tell me to talk," Alex answered bluntly.

"It will get better," Kara told her.

"Yeah?" Alex raised an eyebrow, sitting up. "Are you better? You said we both need sleep. That mean even with Oliver, you can't?"

"OK," Kara abruptly stood up. "You are edging on mean drunk, and I only signed up for sad drunk."

"Oh, that's right," Alex said sarcastically. "I forgot. It's whatever Kara says that goes, right? I mean, screw everybody else. Kara knows best."

"You know what?" Kara narrowed her eyes. "I'm sorry that I was trying to do something nice for you."

"No, I'm sorry I broke the imaginary rules for a weekend I didn't ask for," Alex retorted.

"Then I'm not gonna try to help you anymore," Kara spun on her heel and went to her bed, trying to fight back the tears in her eyes.

"Good!" Alex spat.

"Great!" Kara countered, pushing back the covers and climbing into bed, reaching up to turn her light off.

***

Kara was outside fiddling with the telescope the next morning, a cup of coffee clutched tightly in her hand. She had slept better the night before, but it was far from her best. She still slept better when she was with Oliver.

She heard the door to the porch open, and she barely looked up when Alex stepped outside. "You slept in," she noted.

"Yeah," Alex nodded.

"Good." She straightened up, patting the telescope. "Remember this thing?"

"That was the best thank you gift we ever got for solving a case," Alex nodded.

"Kenny was one of the first people I lost on Earth," Kara remembered. "It doesn't get any easier."

"Kenny Li," Alex nodded.

"Keeper of secrets," Kara smiled sadly.

Alex leaned against the railing, looking out over Midvale. "You know, that's the first time I really understood what I had in you, what it could mean to have a sister. It's crazy to think that I ever thought that you were the worst thing that could happen to me. I'd never get over it."

"Well, I did hog the bathroom," Kara smirked.

"Yes," Alex nodded in agreement, making Kara laugh as she leaned against the railing. "After Kenny, that's when I realized that you and I could get through anything together."

"That's the first time I really became Kara Danvers," Kara agreed.

"It's a good thing, too," Alex smirked. "It got us through the next ten years."

Kara sighed, looking up at the sky. "I remember thinking I would never feel at home on Earth. I still don't, in a way. But I feel at home with you."

"Always," Alex nodded, and Kara let out a breath. "It was a good idea, coming here. I don't think I could have slept in any other bed last night without Maggie." Kara nodded, looking back down into her mug, feeling tears start up in her eyes again. "I'm sorry I punished you for trying to help."

"It was your turn," Kara shook her head, wiping at her eyes.

"I never want to hurt you," Alex began, turning to her, only to stop when she saw Kara wiping her eyes. "What is it? I didn't, did I?"

"No," Kara shook her head, sniffing. "No, it's not you. It's just Eliza . . . she put something in perspective last night." She looked back up at the sky. "Oliver and I . . . how the hell are we going to keep going?" she wondered, making Alex walk over to her. "He's the mayor of Star City, National City needs me to be Supergirl. We barely exist on the other Earth. We make it work now, but in the future? We're serious, Alex. We're really serious, and I love it . . . and it scares me," her voice broke, and Alex put her arm around her. "We'd need to work out the different Earths thing . . . we're not even the same species! I can outlive him, Alex! I don't know how long it'll be, but with Mon-El, I could adapt to living without him. I can't with Oliver. I don't want to miss out on a life like that. You and Maggie would have grown old together, you would've been with each other all the way to the end. Me, I'll just keep living and having to watch Oliver die . . . " Her voice gave way to sobs, and Alex shushed her, quickly taking her mug from her, setting both aside and hugging Kara tightly. "I don't want to see that!"

"You really love him, don't you?" Alex whispered.

Kara broke down entirely, nodding into Alex's shoulders, and Alex realized this wasn't going to be a weekend for just her to get away from it all . . . her sister needed time for everything to sink in, too.

***

Oliver really needed Kara back on Earth-1 twenty minutes ago, he thought as he sat down on the couch in the loft, blowing out a breath and rubbing a hand over his face. William peered over at him from where he sat at the table, doing homework. "Dad?" he asked.

"Yeah?" Oliver blinked, looking up.

"Are you OK?"

Oliver pursed his lips, thinking. In the past day and a half, the team had found several cases of people dead, all bleeding from their ears. Only a sonic scream could make that happen, and it was easy to trace back to one Evelyn Sharpe. Not only that, but Felicity's old Helix friend Alena had shown up with the news that Cayden James was the one pulling the strings now in Star City, and the one who had rescued Evelyn and Talia from Lian Yu while also killing Chase. It made so much more sense now that Evelyn's devices were getting upgraded; James was a master hacker and technology expert, it was no surprise he was giving Evelyn every advantage he could technologically while Talia trained her. He also got to learn how difficult it was to be the Overwatch of the team as he had led Felicity to where she needed to be.

Overall, it had been a rough few days. "Yeah, buddy," he sighed. "I'm fine. Just exhausted."

"When's Kara coming back over?" William asked.

"Hopefully soon," Oliver admitted, pulling out his phone and checking the last text he had received from her a day ago. It stated that Kara and Alex would be in Midvale for at least the weekend, so if he had his timing right, they would be leaving some time tomorrow. Then again, he never knew with how time flowed between the two universes. For all he knew, it was already the end of the weekend. "I can't wait, though – "

He broke off when his phone buzzed, showing an unknown number. "Dad?"

"One second, buddy," Oliver frowned, answering the call. "Hello?" William tilted his head, watching as pure shock overtook his father's face before he grinned. "Hi!" He listened for a few moments, then nodded. "OK. I'll be there." He paused, then chuckled. "Call her yourself. All right."

"That didn't sound like Aunt Thea or anyone else," William frowned.

"It wasn't," Oliver admitted, looking down at his phone.

"Who was it?"

Oliver sighed, looking up. "That was Slade Wilson," he answered, and William's eyes widened. "He needs my help." He smiled, chuckling. "Looks like Kara might be getting here sooner than we thought."

***

On Earth-38, only a few hours after Oliver received his call on Earth-1, Kara and Alex were packing up and ready to head back to National City. "Sandwiches, sparkling water, and pie," Eliza announced, walking out of the house with a large bag.

"You are the best," Kara declared, taking the bag.

Eliza smiled at her. "About Oliver," she said, making Kara bite her lip and Alex pretend like she wasn't listening. "You don't waste a single opportunity you have with him, you hear me? Make sure he knows every day how lucky he is to have you, and make sure you let him know every day that you love him."

"I will," Kara whispered, tears forming in her eyes, these of pure joy.

Eliza smiled, hugging her tightly. "I love you," she whispered.

"I love you," Kara whispered back.

Eliza released Kara, and she went to pack the lunch bag as Alex walked up. Eliza smiled proudly, taking Alex's face in her hands. "Strong girl," she told her. "Brave girl."

"Not yet," Alex shook her head.

"No rush," Eliza told her warmly, hugging her. "I love you."

"I love you," Alex responded.

"Drive safely," Eliza told them.

"We will," Kara promised, then looked down at her phone when it beeped. She read the text she received and snorted. "So, J'onn says to head straight back to the D.E.O., and if we scratch his car, he'll put us in containment."

"Well, you better let me drive, then," Alex said as Kara turned her phone off.

"Why?" Kara protested. "I'm a great driver!"

"You almost killed us twice coming up here!"

"That possum came from nowhere!"

"Keys," Alex held out her hand. "Come on."

Kara sighed, then handed the keys over and went to the passenger's side. "If you're so worried about my driving, why didn't you say anything when we came up here?" she asked.

"Because when we came up here, getting into an accident didn't seem like a big deal," Alex deadpanned, getting in the driver's side and putting her sunglasses on. "Today, I would like to avoid it."

"Progress," Kara grinned.

"All right," Alex put the keys in as Kara put on her glasses. Kara grinned when she heard the music that came on. "Classic," Alex said fondly.

"Yep, turn it up," Kara grinned.

Alex did, pulling back out of the driveway, and giggling, the two sisters started belting out the song as they drove back to National City.

***

They were only about an hour or so out when Kara's phone started ringing. Still giggling as the last classic rock song faded away, Kara brushed her hair away from her ear as she answered, not bothering to check the Caller ID. "Hello?"

Alex was still driving along, barely paying attention, thinking it might have been Winn or Lena or anyone else at the D.E.O. When Kara let out a stunned gasp, she looked over to see Kara's eyes widen behind her sunglasses. "Kara?" she reached over to turn the volume down.

"Slade?" Kara whispered, putting a hand over her mouth, and Alex's eyes widened, too, and she quickly pulled over to the side of the road so Kara could hear better. "Are you OK? Please tell me you're OK!" She must have gotten a confirmation of some kind because Kara relaxed, a wide smile on her face. "Oh, thank Rao. You were starting to scare me! Don't not call for that long!" Alex couldn't help but snicker, and Kara playfully slapped her. "What's going on?" she asked into the phone. Alex watched her, seeing Kara nod, then Kara set her jaw, a determined look in her eye. "Absolutely," she said. "As soon as we get back to National City, I'll breach over. It doesn't matter what you tell me, I'm gonna do it anyway. You really think I wouldn't come? Uh uh." Kara smiled. "I missed you, too."

"What's going on?" Alex asked as Kara hung up.

"Slade's returning to Star City," she answered, turning to Alex. "He's asking for help from me and Oliver."

"Urgent?"

"Very."

"Hmm." Alex revved the car back up. "Then we better get you back to National City."

Kara nodded eagerly as Alex drove back onto the road, taking off at a much quicker speed.

***

"Whoa!" Winn's eyes widened when Kara burst into the D.E.O., running right for her locker, Alex right behind her. "I thought you said you were an hour out! It's been thirty-five minutes!"

"So maybe I broke the speed limit," Alex shrugged, turning to Kara as she found started packing her duffel, her suit included. "How long do you think you'll be gone?"

"I don't know," Kara answered, seeming in a complete rush.

"Whoa, you're going somewhere?" Winn asked as J'onn walked up.

"Earth-1, Star City," Kara nodded, brushing her hair out of her face. "And probably somewhere else, don't know where yet."

"I thought you weren't going to Earth-1 for a few more days," J'onn frowned.

Kara took a deep breath, turning around. "Slade," she said simply.

It was enough to make Winn's mouth form an O in understanding. "I'm not arguing with her," he held up his hands.

"J'onn, let her go," Alex told him.

"Please?" Kara whispered.

J'onn closed his eyes, sighing. "Fine," he conceded, and Kara squealed, grabbing her bag. "Give him our best."

"I will," Kara nodded, then straightened, turning to Alex. "Hey, you could come over, too!"

"What?" Alex blanched. "Um, no, this sounds like your family kind of thing, not mine. I'm nowhere near as close to Slade as you are."

"I know, but what better way to get away from Maggie like another Earth?" Kara suggested, smiling. "Come on, Alex, please. William would probably like the company."

Alex fidgeted, then sighed and turned to J'onn. The Martian rolled his eyes. "I'm losing everyone," he grumbled, then sighed. "If either of you come back with any harm done at all, that's the last vacation you take to Earth-1."

"Oh, right," Kara rolled her eyes as Alex smiled in relief, handing over his car keys. "Because it totally makes sense for me to not visit my boyfriend on Earth-1."

J'onn rolled his eyes fondly. "Go."

"Meet you at the loft?" Alex asked Kara.

"Yeah," Kara grinned widely. "I can't wait."

Alex couldn't help but smile; Kara's glee was contagious. "It's good to know Slade's OK," she admitted as they walked out.

"Yeah," Kara agreed. "And I'm going to make sure he stays that way."

Alex laughed that time. "Yeah, I bet you will."

She grabbed her motorcycle and drove off towards her apartment, Kara leaping into the air and flying towards her loft, a smile spreading across her face. After so long, Slade had finally not only managed to call, but had also called with news about his son.

She landed in her loft and took out her phone, immediately calling Lena. "Hey, Lena?" she said. "I'm going to need a few more days off." She smiled as she turned to look outside. "Slade's back."

***

Bad news, guys - the Deathstroke episodes aren't gonna fit in this book.

They're way too important to be stuck here, which means they're getting their own book! :D Surprise! How could I not have the opportunity to make sure I had as much time as possible to write out the adventures of Oliver, Slade, and Kara in Kasnia?

So, everyone . . . to be continued in "Between Two Worlds," which I promise to get up ASAP!
