Hehe, I love this chapter. There's the suit-up scene at the end, but it's the parts before that that make the chapter for me.

Enjoy!

Kara walked into the dark lab, where Thawne was crouched over the Prism. "Will it work?" she asked.

"It will," Thawne looked up at her. "With a few adjustments and a significant power source."

"My husband's on his way to handle that as we speak," Kara nodded.

"Your husband," Thawne scoffed, "has a choice to make."

"Me or the Reich?" Kara guessed, frowning.

"That's right," Thawne set his tools down, turning to her. "Because we have two goals, and my worry is if we can't accomplish them both, he's gonna choose you over a second Earth flying under our banner."

"Oliver will not abandon our mission," Kara said confidently.

Thawne huffed. "I've seen this before. In 1945, Hitler and his men were equally shortsighted – "

"Hitler was driven by passion and childish need," Kara narrowed her eyes. "Oliver is ten times the man Hitler ever was!"

"Not when he's blinded by his love for you!" Thawne snapped.

Kara scowled, then looked down. "If it comes to Oliver choosing between me and the Reich, I'll make sure he chooses the Fatherland."

"How?" Thawne narrowed his eyes.

"If it comes to it," Kara narrowed her eyes right back, "by taking the choice out of his hands!"

Thawne scoffed, clearly not believing it, but before Kara could reprimand him, a cold voice behind her spoke. "I see you continue to question your superiors, Thawne."

Thawne stiffened, then narrowed his eyes. "Watch your tone."

"My son is dead, and you're telling me to watch my tone?" The cold voice turned even colder. "Do you have a death wish?"

"Finish with the Prism," Kara ordered Thawne.

He growled, but returned to his work. "Sorry for your loss," he tossed over his shoulder in disinterest.

Kara heard the man behind her growl, but she turned and walked off, beckoning with her hand. She heard her fellow general's footsteps follow her, then stopped when they were a good distance away from Thawne. "I am sorry for your loss," she whispered. "Tommy didn't deserve to die that way."

"No, he didn't," Malcolm Merlyn agreed, stopping by her side. "But he chose to die before betraying his best friend, before betraying you."

Kara's eyes hardened. "Oliver has sworn his death will be avenged." She turned to look at him. "They will try and find us."

"And I will be watching your back, like I always have," Malcolm told her.

"They have their own version of you," Kara warned.

"Our records said he was dead." Malcolm snorted. "It would seem I'm a magician here as well."

"Well," Kara smirked. "He's not the Reich's Magician."

"No," Malcolm agreed with a matching smirk. "He's not."

"They have Kryptonite arrows."

"They also have their own version of you."

"She's not me."

"No, she's not," Malcolm agreed. "But did the Kryptonite arrow hurt you?"

"No," Kara shook her head slowly. "Not much."

An evil grin came over Malcolm's face. "What about her?"

Slowly, Kara grinned back. "I like the way you think."

Oliver stood looking over the blueprints of S.T.A.R. Labs, barely looking up when he heard footsteps approach from behind. "There's the choice for you to accompany my wife if you want to choose that instead," he tossed over his shoulder, though he was smirking when he said it.

There was a snort from behind him. "And what do you think my answer to that is, Oliver?"

There were only a select few people who could still call him that, and it made Oliver chuckle. "Like old times," he answered.

"Like old times," Slade Wilson confirmed, walking up to Oliver's side, looking down at the schematics. "This is where we're hitting?"

"This is where Thawne can do the surgery to save Kara," Oliver confirmed. "They'll be expecting all of us in one place. They won't expect a small team to hit the labs."

Slade nodded, then looked at Oliver. "Something else is on your mind."

Oliver narrowed his eyes. "She's with them."

Slade frowned. "She won't be able to do anything with these . . . heroes, much less lay a hand on your wife."

"Still," Oliver growled lowly. "To see her face again . . . "

"Doppelgängers or not, heroes or not, we're going to save Kara," Slade told him firmly. "You've never let her down before."

"I know," Oliver nodded curtly, tapping the tablet and turning it off. "Let's move." He reached up to his comms. "Black Arrow and Terminator, moving out."

"Magician, copy," Malcolm's voice responded.

Oliver grabbed his bow, and he and Slade left the base side by side, heading for S.T.A.R. Labs.

"Maybe tracking her off of face cream would've been easier," Caitlin muttered as the techs of the heroes worked in the back lab.

"Supergirl-X's blood is filled with solar radiation, more than it should be," Harry leaned forward, working on his computer. "But if I could try to get that to act as a kind of beacon . . . "

"Hey, ah . . . " Mick cleared his throat, getting off the medical bed, then walked up behind Caitlin. "How do you do it?"

Caitlin frowned. "Do what, Rory?"

"Bring the other you out of you."

Caitlin sighed. "You don't want to know."

"Sure I do."

She rolled her eyes, then answered. "It happens when I am scared or angry."

"Oh," Mick nodded thoughtfully. "So if I were to, um . . . " He leaned forward right in her face. "Boo!"

Felicity closed her eyes, thunking her head back against her chair. Harry and Lena exchanged exasperated looks, and both Alex and Winn looked over at Mick incredulously. "Seriously?" Winn asked in disbelief.

"Nice try," Caitlin snorted.

"Boom!" Harry announced.

"Got it!" Lena shouted at the same time.

Both looked at each other, then Harry pointed at himself. "My city."

"Mine's on another Earth," Lena countered.

"You took the neutron bomb reveal!"

Lena huffed. "Touché."

"Thank you," Harry smirked, turning to the others. "Whatever's going on with Kara-X's blood, it's intensifying."

"Worse for her is better for us," Felicity grinned.

"Better for us for tracking her, at least," Caitlin nodded. "We should have her location any minute."

Barry and Iris stood in Thawne's vault, looking over images of him as Wells and as the Reverse-Flash. "I can't believe he's back," Barry whispered. "I don't know if I'll ever be rid of him."

"I know," Iris told him. "And I know how much you're hurting."

"I just keep looking for closure, but every time I see him, all I see is – "

"Your mother dying," Iris finished, looking up at him. "You're gonna stop him."

"How do you know?" Barry asked.

"Because you always do," Iris smiled fondly.

"And because we're not gonna let you do it alone," Oliver added as he walked in. "We're getting close on a location."

"And we just got one," Laurel said, and the three turned around to see her walk in, Slade behind her. "Felicity got a match."

"They're at a shipping depot outside Danville," Slade nodded.

"All right," Barry nodded back. "We'll get the band back together."

"You all coming?" Oliver asked.

Slade snorted. "You kidding, kid?"

"Wouldn't miss it," Laurel grinned.

Sara picked up her bo staff from where it rested across the S.T.A.R. Labs table, snapping it to full length. She turned around to see Laurel twirl two knives around before placing them in sheaths on her legs. "You ready?" Laurel asked her with a smile.

"Hell yeah," Sara couldn't help but grin.

Laurel grinned back, the two Lances walking out of the room together.

***

Jax walked into the lab Stein was waiting in, wordlessly holding out his hand. Stein reached for his without hesitation, and the two clasped hands, merging together into Firestorm.

***

Thea slid her sword into place on her back, then picked up her bow, double checking its weight in her hand. She turned around as Malcolm slid his sword into his sheath, then looked up at her. Father and daughter exchanged nods, walking out of the room.

***

Barry took a deep breath as he stood in the cortex, then pulled his cowl on, lightning flickering in his eyes.

***

Alex slid her brass knuckles into place, clenching her hands into fists, making sure the grip was correct. She rolled her shoulders back, then picked up the two guns that were on the table next to her. She raised them, checking the grip and aims of those before sliding them into the holsters on her legs.

Ready to go, she turned around as Slade finished with the weapons on his body. They walked out of the room at the same time, matching each other's strides effortlessly.

***

Oliver finished adjusting his gauntlets, then looked up when he heard a rush of wind. One second Kara had been in front of him in a button-up shirt and jeans, and now she was in full Supergirl attire. "Keep up," she teased.

Oliver snorted. "Angel – "

"Yeah, yeah, superspeed, you don't have it," Kara rolled her eyes as he put his mask on.

Oliver smirked as he flipped his hood up. "You say it like I've told you that before."

"I wonder," Kara mused sarcastically.

Oliver snorted again, picking up his bow. "Let's go."

***

They walked out of the breach room and were joined at once by Alex, Slade, and Barry from the other direction. Malcolm, Thea, and Firestorm joined them a little further down the way. Sara and Laurel were waiting on opposite sides of the hall, and Sara blinked when she saw the suit Alex was wearing. "Is that my sister's suit?!"

"Right," Alex winced, remembering. "Yeah, it is."

"She deserves it, Sara," Oliver told her as the two Lances joined the line.

"That's part of why I was worried about taking it," Alex hissed.

"Oliver's not wrong," Malcolm shook his head. "If anyone between our teams deserves it, it's you."

"Sentimental now, are you, wizard?" Slade raised an eyebrow.

"How many times do I have to tell you it's magician before you get it right?"

Slade hissed and Malcolm yelped simultaneously, both reaching for the backs of their heads. They turned around to see Laurel step in between them, smiling sweetly. "Are you two done yet?"

"Or are you going to continue being children?" Kara couldn't help but throw back.

Alex and Thea laughed as Oliver smirked. "You heard her," he tossed back as well.

"You're lucky we like you guys," Malcolm grumbled as they walked out of the labs.

"All right," Kara rolled out the kinks in her neck. "Let's go."

"Brace?" Slade turned to Alex, raising an eyebrow.

"Copy that," she nodded.

Sara and Barry blinked, wondering what she meant, when Kara grabbed them by the backs of their suits, taking off into the air. "Oh," Barry blinked. "So that's what that means."

Oliver, Malcolm, and Thea shot grappling arrows into the air, and when three thunks signaled they hit their mark, Malcolm turned to Laurel, raising an eyebrow. "Once more, unto the breach?"

Laurel smirked, wrapping an arm around his neck as he put his free arm around her waist, and Oliver and Thea swung off, Malcolm carrying Laurel with him. "That is so weird to see," Sara shook her head in disbelief as Firestorm took off after them.

"Guess we really don't know much about what's happened," Barry shook his head, then turned to Sara. "Do you mind?"

"Go ahead," Sara smiled.

Barry nodded and picked her up, quickly speeding after the others to catch up.

Hahahahaha - SURPRISE! :D

Now how could I possibly resist not including more members of Team Earth-X? And what better ones than Slade and Malcolm?

The heroes vs Nazis will be coming later!
