Flash
After Team Flash had their encounter with Black Siren, Barry, Cisco and Wells came up with the idea of using vibrational tech to take out all the Earth 2 metas at once.
"So, exactly are we going to do this?" Joe asked as they looked at the device that Cisco and Wells had created.
"So all matter vibrates at its own unique frequency, right? You disrupt that frequency, you disrupt the matter." Cisco explained.
"Like how an opera singer shatters glass with her voice." Iris said.
"Exactly. So we found out that all Earth-2 people vibrate at their own, - more erratic frequency." Cisco said.
"- Higher frequency." Harry insisted.
"- Different frequency." Cisco tried.
"- Higher." Harry insisted.
"- Higher frequency than we do." Cisco conceded.
"- Right." Thea said.
"So I ran this all past Hartley, right? And he postulated that we could create a sort of dimensional tuning fork Voilà Â." Cisco said, only to have Harry interrupt him.
"Okay, you didn't do it yourself." Harry said.
"Just let me have this one, okay?" Cisco asked.
"- Have it, have it." Harry said.
"- Thank you. So if you run around the city fast enough to create a refracting field, the device can send out a pulse that'll bounce off of it, split apart, and collide with itself over and over." Cisco said.
"Amplifying it to an erratic frequency on the Earth-2." Barry said.
"- Higher." Harry corrected.
"- Higher frequency on the Earth-2 spectrum." Barry said.
"And when that pulse hits anyone from Earth-2." Cisco said.
"It'll disrupt their nervous system." Caitlin said.
"Earth-2 metas go night-night." Cisco said.
"- Even Zoom?" Iris asked.
"- Even Zoom." Cisco confirmed.
"Harry and Jesse are from Earth-2. How do we keep the pulse from hurting them?" Joe asked.
"Oh, Detective, I didn't know you cared." Harry said sarcastically.
"Yes you did." Joe said.
"Uh, we designed these headphones to protect us from the pulse." Wells said, revealing a pair of headphones.
"Beats by Wells." Cisco laughed as alarms beeped.
"Cisco, it's your metahuman alert app." Caitlin said.
"That's the high-rise development on the west side." Joe said.
"Hundreds of people live there." Iris said.
"Ramon, we're up. Let's go. Set that pulse off right now. Allen, you need to start generating that refracting field right now." Harry said.
"But Black Siren can take down this building at any point. Wha all those people, Wells." Barry insisted.
"How many more people are gonna die while we wait?" Harry asked.
"Guys, which is it?" Joe asked as Thea got an idea.
"I think we can do both actually." Thea said.
"What do you mean?" Cisco asked.
"Barry isn't the only speedster in the room and while I may not be as fast as him, I should be fast enough to do the running around the city while he handles Black Siren." Thea said.
"She's right." Cisco said with a grin.
"You got her suit ready?" Barry asked.
"Thought you'd never ask. Get out there and deal with Black Siren while we worry about the field." Cisco said and Barry nodded as he sped out.
"So where's my suit?" Thea asked as she followed Cisco back to the cortex where he revealed another mannequin, which after he pulled the tarp off, revealed a mostly red suit, though there were streaks of yellow bolts at the waste and on the arms, along with a yellow lightning themed design at the chest and a red mask.
"This looks awesome." Thea said.
"Ready suit up Speedy?" Cisco asked.
"Like you wouldn't believe Vibe." Thea said with a grin as lightning crackled in her eyes and she sped out, taking the suit with her.

"So, why exactly did you force me to come down here?" Felicity asked, peeved at her ex.
"Because I figured you could put your whole being mad and distant at me thing on hold until after we've stopped nuclear apocalypse." Oliver said, shutting her up.
"You figured right, but can someone bring me up to speed?" Felicity asked as she took her old seat at the computers.
"Darhk stole Rubicon from Lyla, which apparently means that he can now launch any nuke in the world." Oliver said as Lyla entered the Bunker.
"I just got off the phone with the DOD and it's not good news." Lyla said.
"How bad are we talking?" Laurel asked.
"Russia, Markovia, Corto Maltese, us, every NATO Ally- Rubicon has control over all their nuclear systems." Lyla said.
"You mean HIVE does." John corrected.
"I know it's a little late for this, but whoever created an algorithm that could override any country's nuclear weapons really screwed up." Felicity said.
"That would be Amanda Waller." Lyla said.
"How much time do we have?" Oliver asked.
"We? Oliver, I'm the director of Argus, and this goes way over my head. This is executive level, and this is Department of Defense." Lyla told him.
"Roughly 21 hours. That's how long the countdown sequence is before Darhk can actually launch a nuke." Lyla said.
"Which means we have 21 hours to stop Rubicon before the world ends." Laurel said.
"You're gonna have to find a way to interrupt that sequence." Oliver told Felicity.
"Rubicon is a failsafe against nuclear Armageddon. Argus designed it to be 100% unhackable." Lyla protested.
"No. She can do it. She's the best." Oliver said confidently.
"Well, actually, that would be my father as far as Rubicon is concerned. It uses Fourier protocols. Noah practically wrote the book on them. The world is facing nuclear Armageddon. My pride and my general dislike for my father can take a backseat for the next 20-plus hours." Felicity said.
"Felicity, this isn't about pride. Your father's a criminal. He can't be trusted." John said.
"I'm not saying we should trust him. I'm saying we need to." Felicity said.
"Ok. He got out in Darhk's jailbreak. How do we find him?" Laurel asked.
"I'm already running a search." Felicity said.
"You certainly got back into this routine rather quickly." Oliver said.
"Don't get any ideas Oliver. I'm only doing this to save the world. Once Darhk is dealt with, I'm done. For good this time." Felicity said and Oliver nodded in agreement.
"That's fine with me. So long as we can actually live long enough to get there." Oliver said.
