Julian drank from a bottle of water as Barry and Oliver and Felicity treated him. "Thanks. Really."

"He's just a bit dehydrated but he needs a lot of rest." Felicity said before turning to the computer. "There were traces of sodium thiopental in your system."

"A truth serum." Julian nodded as he looked at everyone. "If it hadn't been for you, it would've been a lot worse for me. Thank you for help."

"Julian, what happened to you?" Barry asked as Julian took a breath..

"I was in England, trying to move on after… you know. I had been working as professor of history in Oxford, when last month, someone attacked me in my apartment and knocked me out. Next thing I remember, I woke up in a dark room, cuffed to a chair and a woman named Mercy Graves was interrogating me about when Caitlin… Killer Frost kidnapped me two years ago. I tried telling her that I didn't remember anything but she used a truth serum. Made me tell her everything. About you, Team Flash…" Julian looked down in shame, wiping his face. "I… I tried to resist and fight but…" He looked at Barry apologetically. "…then I just couldn't take it anymore."

"Look, it's not your fault, OK?" Barry assured as he knelt down with a consoling look in his eyes, holding Julian's shoulder.

"Where's Caitlin?" Julian asked worriedly. "Please, tell me she's alright, Allen."

Barry sighed, about to break more bad news to him.

"Julian's testimony will not add up." Joe told Barry after Julian seemed clearly shaken up. "You've seen the state he's in, they'll say he was in delirium and his memories foggy."

"We gotta do something to take Lex down." Barry said.

"Maybe there is another way." Cisco came up with an idea. "If I can vibe Mercy…"

Elsewhere

Dinah, wearing a white top and pants, tried to use her Canary Cry but nothing happened as she was strapped to a chair before one of the men injected a liquid into her neck.

"Why…" Dinah murmured weakly. "Why… are… you… doing this…"

"You're a killer." A guard said, glaring. "You killed dozens of criminals with no regard for their life, all in name of your dead partner, bitch. And yet, the Green Arrow recruited an unstable monster like you."

"You… you can't do this…" Dinah whispered. "I… I have rights—"

"Did you read the people you killed, when hunting Sean Sonus, their rights? Did you give them a chance to stand down and arrest them before you tortured them?" Another guard asked and Dinah remained silent. "Didn't think so."

"You metahumans think that because you have powers, you can do anything you want, to anyone you want and walk away with it."

"The same goes for that doppelganger. What was her name again? Black Siren. She was so close to staining Laurel Lance's good name… she was associated with… two psychopaths, if I recall—"

"Don't you dare using what we did to rationalize and justify what you are doing." Dinah sneered.

"There is a price you must both pay for your crimes, freak." One of the guards knelt and neared Dinah, glaring.

"What are you going to do to us?" Dinah demanded.

"If it were up to me, I'd just put a bullet in you both and be done with you. But the boss thinks we should contain you." The guard replied.

"So, you just round up all the metahumans you deem dangerous and lock them up forever?" Dinah scoffed.

"No." The guard shook his head. "The boss wants to find a way to control your powers, eliminate them. So that you can all go back to living what is left of your lives. If we can't, well…" He trailed off as the guards had sadistic smiles on their faces.

"Could have just put out a doctor ad." Dinah snapped as she was trying to free herself from the chair but the restraints held her down tightly.

"Do not struggle. There's no point."

"She likes to scream so much, let's give her what she wants. Scream for us, Canary."

One of the men injected a syringe above Dinah's breast as she hissed in pain as the needle pierced her skin and the red liquid entered her heart and bloodstream and in that moment, Dinah felt like if her entire body was on fire. She thought she had known pain, when her partner and lover Vince died in front of her but this… this was pure agony as she was screaming, while in excruciating pain as one of the men ran his fingers down one of her scars on her back.

"I heard that they tortured you once and killed your partner right in front of you, when you became a meta. I wonder what it felt like… to feel every cut and bullet wound…" She felt them touch more of the scars on her back and on her abdomen and shoulders as she kept on screaming as if she was reliving every cut and bullet wound she had ever endured, while starting to sob in pain.

"How did your victims feel, when you tortured them, huh? Can you imagine every bone in your body being crushed under the pressure of sonic waves?"

Dinah kept on screaming, reliving the worst pain she had ever endured in life, in her mind begging for the agony to stop.

Four years ago, Central City

Dinah was restrained to a chair in a workshop as in front of her was her partner and lover, Vincent Sobel, on his knees and Sean Sonus was aiming his gun at Vince from behind as Dinah sobbed. "Sean, I am begging you, please…"

Sonus laughed before an energy wave of dark matter flooded the workshop and Sonus pulled the trigger, executing Vince and Dinah screamed in pain and unleashed her sonic scream for the first time, ever. "Noooo!"

Present

"Where am I?" Laurel demanded as she was in a room, where in front of her was a mannequin, restrained to a chair.

"Use your sonic scream." Someone ordered through a P.A. system.

"What?" Laurel demanded.

She felt the jolt of electricity jolt through her neck because of the chip they planted in her and every other metahuman they had captured.

"Do it."

Laurel swallowed before unleashing her Siren Cry at the mannequin, that crushed under the pressure of sonic waves.

A.R.G.U.S.

"Experimenting on metahumans?" Lyla repeated.

"And I'm pretty sure they're illegal and with no trial…" Barry tried to explain.

"If you had come earlier…" Lyla sighed, wiping her face.

"What?" Barry asked.

"I just got a call from the White House. They want support of A.R.G.U.S. and list of any potentially dangerous metahuman that may have committed crimes in the past and apprehended them and contain them, by any means necessary." Lyla explained as Barry groaned in frustration. "Technically, the Flash isn't considered a threat but…"

"…every other meta that is out there is not safe." Barry realized and Lyla nodded.

"Wait, how do you even know all of this?" Lyla asked before turning to Cisco. "Did Cisco—"

"Julian Albert. He's a friend." Barry explained. "They kidnapped him and interrogated him and he told them everything he knew about Caitlin. They worked for a woman named 'Mercy Graves'. She works for Lex and she's basically his muscle."

"Graves?" Lyla asked.

"You know her?" Barry asked.

Lyla nodded. "She used to be one of our black ops assets. Specialized in capture, torture, interrogation. If Waller needed to quickly catch someone and make him talk, she'd call Mercy. That was before she took Oliver in in Hong Kong. After that, Mercy became a ghost pretty much."

"Maybe if we can find Mercy, we can make her talk." Oliver said.

"Wait, and torture her?" Barry asked.

"Do you have a better idea?" Oliver demanded before turning to Cisco.

"I tried vibing Caitlin and Julian before that but…" Cisco sighed. "I don't know, all I got is big black nothing. It's like if they put on a curtain to make me not see anything. I don't know how but they have some kind of anti-vibe countermeasures."

Oliver sighed as he turned to Barry. "Barry, I know you're against it but—"

"It's Caitlin we're talking about. We need to find her. Whatever it takes." Barry said.

Elsewhere

"They better not be able to detect us." Lex said.

"Don't worry. From what we could learn about her, I think we'll be able to counter Ramon's power with no problems." The doctor said as on monitors was Gypsy, in prisoner uniform, restrained to a chair and some electrodes attached to her head. "Understanding her powers will help protect our facilities from any unwanted eyes."

"She'll be able to help find Allen?" Lex asked.

"We'd need to force her to cooperate." The doctor turned to Lex nervously. "But, sir, isn't this a little… too far? Inhumane?"

"You've seen what they've done and what they're capable of." Lex turned to the doctor.

"I thought we were supposed to offer to cure them of their abilities." The doctor pointed out.

"We will." Lex nodded. "But first, we need to understand how do their powers work. How much did the dark matter affect them."

"So, we keep them here, with no trial, no—"

Lex cleared his throat before showing some of the prisoners on screen. "Kyle Nimbus. A criminal and hitman. He was supposed to be executed on 11th December 2013 with a poisonous gas but the dark matter turned him into a poisonous gas. After that, eleven months later, he killed an entire criminal family of Darbinyans, Judge Howard and attempted to kill Detective Joseph West in Iron Heights.

Adam Fells. Tried to create an earthquake and hurt dozens of innocent people in progress.

Leslie Jocoy, also known as Amunet Black. Criminal and black market dealer, trying to illegally purchase metahumans and… Caitlin Snow, a.k.a. Killer Frost. One of her… former lackeys. And Laurel Lance… or some kind of her… double and Dinah Drake. Sonic scream ability. Both of them killed dozens of people too."

"Doesn't she work with the Flash?" The doctor questioned, recognizing Caitlin as Lex showed her the photo of Killer Frost.

"Before that, she was responsible for deaths of dozens of people… associating herself with a dangerous speedster. She is a wild card she needs to be kept in check." Lex explained.

S.T.A.R. Labs

"OK, this better work. We find Mercy and make her talk." Oliver said.

"And if Luthor or someone else tries to order a manhunt, we can leverage that we have footage of Luthor kidnapping and experimenting on metahumans and threaten to leak it all on the Internet." Barry said.

Elsewhere

"Tell me what do they plan now." Lex demanded as he knelt across a Hispanic woman, who was restrained to a chair and had electrodes attached to her head.

"I… I don't know." The woman pleaded.

"Ran out of vibes? Maybe you need an incentive." Lex pulled out a remote and pressed a button as Gypsy screamed in pain.

Mercy Graves was going out from the bathroom in normal clothes before in front of her appeared the Green Arrow, notching his arrow.

"Mercy Graves. You have failed this city." The archer said.

"And you have failed humanity, Mr. Queen." Mercy smirked and Green Arrow blinked in surprise. "You think I don't know who you are? You're on the wrong side. The metahumans are a threat that needs to be kept in check."

"You're illegally kidnapping and experimenting on people." Oliver said.

"They have brought this on themselves." Mercy said coldly, smirking. "Besides, you must be an idiot to come after me alone. Over twenty of elite trained men are coming to take you in, as we speak."

"What makes you think that I'm alone?" Green Arrow smirked as the door opened and Mercy paled to see a man in an armor with blue plates and a belt of grenades across his chest, black sleeves, holstered guns on his belt and legs and half orange, half black helmet and holding a sword, running the bloodied sword across Mercy's couch to clean the blade.

"So much for the twenty elite trained men." Deathstroke said.

So, what do you guys think?
