If this doesn't end in the next two seconds, I'm going to jump off this building after Sherlock. Personal safety be damned.
Cisco uses those sound thingies and Sherlock falls over. Cisco brutally crushes Sherlock's injured hand under his boot. Sherlock groans. Cisco leans down and touches right between his shoulder blades. The vibrational waves surrounding him pulse for an instant.
Sherlock screams.
Sherlock screams.
Sherlock screams.
I'm definitely jumping off this building.
Cisco will kill me if the fall doesn't.
I can't bring myself to care. Sherlock's suffering and I can't help from up here.
Then something snaps in Cisco. I can see it from here. He's back to himself. He stares at his bloodied hands. Then, suddenly, he leaps into the breach he opened and vanishes.
Cisco
I can only think of one thing. WhathaveIdonewhathaveIdonewhathaveIdone? What. Have. I. Done.
I keep seeing Sherlock, crumpled, screaming. Anyone can break. And, apparently, I broke him. The strongest man I've ever met, Oliver included. And I broke him. And I enjoyed it.
Like Reverb when he beat up Barry.
His voice echoes in my head. Speak to me like that again and I will shatter your entire nervous system without breaking a sweat.
That's what I tried to do to Sherlock. I'm not as good, but I'm getting closer. That pulse to his nervous system...Any more power and I would've shattered his nervous system. I can't imagine how much what I did hurt.
I'm sitting in my workshop. Surrounded by my tech. This place usually comforts me, but today I just feel...numb.
My mind is ruthlessly comparing what I did to Sherlock with what Reverb did to Barry. Pretty similar.
Barry knocks on the door. "Cisco?"
I don't reply.
"Cisco?"
I don't want to talk.
He drags my name out. "Ciiiscoooo? I know you're in there. Talk to me."
I ignore him.
Being Barry, he just phases through the door. "Dude. Are you okay?"
I drop my head. "I'm not the one you should be worried about. More like my victim."
Barry winces. Victim is an ugly word. "Sherlock will be fine. He's tough."
I can do this thing where I distort the air and make pictures. I create my memories of Sherlock. It's from my perspective, like a movie. My hand darts into the picture. It taps Sherlock's back, just between his shoulder blades. Sherlock screams and falls over. I add a memory of Reverb, threatening to shatter Killer Frost's nervous system. Then I add Reverb pummelling Barry. I line all three up, with Sherlock in the middle framed by two Reverbs.
Barry flinches. "Okay, okay. I get your point."
I put my head in my hands. "Please just leave me alone."
Barry hesitates. I look up at him, knowing I look broken and lost. Something he sees in my eyes makes him back off. "Okay. I'll...talk to you later, I guess."
He leaves. I look up at my image of Sherlock screaming. Something breaks inside me, and I curl in on myself into a little ball.
John
Cisco races off into the breach. Barry races after him.
I look at Sherlock, crumpled on the ground, and turn to Oliver. "Can you get me down there? Now?"
He shoots an arrow attached to a rope at a nearby building. I grab him, and he pulls me off the building. We swing by the rope, and he drops closer to the ground. I let go and drop to the ground, already running to Sherlock.
I roll him over and look at him. He looks awful.
I ask him, "What happened?"
He smiles. "You're the doctor. You tell me."
I give him a tired smile. "Superheroes and fighting techniques are not my specialties."
"Alright. He did something to my back, right where the spinal cord starts. Targeting my nervous system with a...pulse, I suppose."
Caitlin gasps through the mic. "Like Reverb."
Sherlock, unsurprisingly, already knows about this. "Cisco's doppleganger, right?"
Her voice cracks. "Barry told me that Reverb said that he could shatter someone's nervous system without breaking a sweat."
Sherlock smiles. "Well, lucky for me that Cisco can't do that yet."
I flatten my mouth into a line. "Any lightheadedness, dry eyes or mouth, muscle weakness, twitching, paralysis, pain, sensitivity, numbness, tingling, prickling, or burning?"
Anyone else would have to ask me to say that again slowly. Sherlock just sighs. "John. If I had nerve damage, I would know. I suppose, if you want to be technical, I am experiencing a huge amount of pain right now, but not from nerve damage. Just aftereffects. The worst's past."
Oliver
John groans quietly and rubs his eyes. "Bloody hell. Is there anything I can do to help?"
"Nothing, unless you know how to make my nerves stop hurting. Cisco was trying to destroy my nervous system, and he almost did. If he used any more power I'd be dead right now."
John's head snaps up. His face cycles through horrified, scared, angry, but settles firmly on distressed. Almost to himself, he mutters, "Bloody...That must've hurt."
Sherlock smiles quietly. "Worst pain I've felt in my life."
Alright, that surprises me. John asks, "Including being shot? At point blank range? And being tortured? For a year?"
"Yes, John. I do believe those both fall under the category of things that have happened in my life. That Cisco is very powerful. It's like what Donovan loves to remind me of. The best good guys make the best bad guys."
