Nora stayed at Peter and Caitlin's place that night and they didn't push her into explaining exactly what happened and Harry has an idea on where to find the shard of the satellite where the dagger could've come from and they've hit another dead end with finding Thomas.

"There's no more hidden messages we could use." Caitlin explains. "A satellite to run DNA recognition patterns could be helpful but...I though losing him when I was ten was hard, but, the idea that he's out there and I might not be able to find him.."

"Maybe I can help you." Cisco offers.

"Thought your powers don't work with your hands ripped." Peter reminds him.

"No, not fully, but this I can do." Cisco tells them and places his hands on Caitlin's elemental table and gets a vibe of Caitlin's father and sees a valentines party invitation dated '99 and him writing something on a board before exiting his vibe abruptly.

"You okay?" Caitlin asks.

"I saw him." Cisco tells her. "I saw your dad in...in an office, sketching something in a notebook. I couldn't quite make out what it was."

"You see anything else?" Peter asks.

"Equations on a chalkboard." Cisco answers.

"We didn't have a chalkboard in our home office." Caitlin replies.

"Tell us everything." Fox asks, been researching Caitlin's family half of last year.

"He had an ID. It was like, yellow logo, like a yellow state building." Cisco says.

"Not a state building. University." Fox corrects him. "Hudson University."

Everyone looks shocked as they know someone else who went there. "Professor Stein."

"I knew he admired him, I didn't realize they were friends." Caitlin says.

"Wonder why Stein never mentioned that." Peter says since they've met the professor multiple times, he even was a part of their team for a few months before leaving with the Legends.

"Let's get going." Fox says and leads them off.

-

They make it to Hudson and to Stein's old office and are wondering what Thomas was doing here.

"Cisco think you could vibe the chalkboard?" Ralph asks and Cisco gives it a shot.

Cisco vibes some equations and quickly writes them down.

"Hydrogen chains bonded over and over." Peter tells from the equation.

"Two oxygen at absolute zero." Cisco adds. "It's like it's making heavy water."

"Close, but not quite." Fox says. "It's creating ice."

"It's also another one of my father's hidden messages." Caitlin says and quickly deciphers it.

K H I O Ne

"Khione?" Caitlin questions.

"What kind of message is Khione?" Cisco wonders.

"One I'm familiar with." Fox says and quickly draws something he got from his foundings. "That sketch you saw Thomas drawing, did it look like this?" He asks and shows his drawing to them and it looks like a woman with long hair and something on her head.

"Are you a speedster?" Ralph asks, looking at how fast he drew that.

"You get into the habit of writing fast when you write the books for Wayne Enterprise." Fox jokes and shows the picture to Caitlin and to her it looks like her.

"My father was drawing me?" She asks.

"No, that's Khione. While trying to learn about Killer Frost, when she was Killer Frost, I discovered Khione. The Greek goddess. Child of the North Wind, whose realm was all ice and snow." Fox explains as Caitlin and Peter are shocked at that.

"That would mean whatever your father was doing here, he knew that there was two of you." Peter realizes.

"It stands to reason that Thomas was there when Crystal first appeared." Fox says.

Caitlin looks down at the picture and wonders how far this pit of secrets go. "So, he knew the truth about Crystal Frost? He knew who I really am?"

"Possibly." Fox says.

"Did I scare him away?" Caitlin wonders.

"No, come on, Cait. This wasn't your fault. We will find where he is, he wouldn't ask you to find him if you scared him." Peter says and Cisco takes the picture to vibe it and sees something called Viera chemicals. He got a few quick vibes about Caitlin, Crystal and a few from their past experiences as is hit out of the vibe.

"You okay?" Caitlin asks.

"Yeah, just lost my footing for a second." Cisco says as he leans on them for support.

"You see anything?" Fox wonders.

"You ever hear of Viera Chemicals?" Cisco asks.

"It's an old chem lab out in the Bareens, but it's been shut down for years." Caitlin tells him.

"Well, we know our next stop." Peter guesses as they leave.

-

When they made it to Viera chemicals, they see it was burned down and that's why it was closed down.

"When did this happen?" Caitlin wonders.

"The same night your father vanished." Fox says and Peter finds a lot of the same thing.

"This is a lot of liquid nitrogen." Peter says. "If this place is filled with it, this place would've gone sky high."

"So, all my father's work is completely gone?" Caitlin asks.

"Not necessarily." Ralph says. "Police listed this fire as accidental, but they didn't know about the connection to Caitlin's father, so..."

"Ralph, my father told me to come find him." Caitlin says.

"Yeah, I know that, but a guy who disappears on the night of a warehouse fire and who's hard to find?" Ralph questions.

"Well, if you're thinking this was arson, that Thomas did this, he would need some help covering his tracks." Fox says and Ralph finds a Tannhauser box.

"Listen, my mom may not be the best person, but there's no way she'd be party to something like this." Caitlin says.

"There's one way to find out." Ralph says and looks to Cisco.

Cisco takes the box and instead of fibbing, he starts spazzing out and his nose starts bleeding.

"Cisco?" Caitlin asks when he falls and Peter catches him.

-

They brought him back to Star labs and learned that his wounds are worse than they thought.

"While you were unconscious, I scanned your wounds." Caitlin tells Cisco. "There are still trace amounts of aluminum beryllium alloy fused within your hands. It's remnants of Cicada's dagger."

"See, this is what I needed. I just need rest." Cisco says.

"Cisco, rest isn't gonna be enough, pal." Peter interrupts his friend. "Every time you use your powers, the dark matter is going to affect your central nervous system, causing you more and more pain."

"Which you must have been experiencing all day today." Caitlin states. "Why didn't you say anything?"

Cisco lays down on the med bed. "Because you're my friend and you needed my help." Cisco tells her.

"Okay, But I would never ask you to hurt yourself. Every time you vibe, you are going to have more and more seizures." Caitlin tells him.

"Then what am I supposed to do?" Cisco asks as he jumps up. "I remember when these powers were a curse. Seeing Thawne kill me lever and over. The darkness, I didn't want it. These powers were a part of me. I had to learn that. And when I did, they showed me everything. I could give every clue, breach us wherever we needed to go. Bring my value to the team. If I can't take the pain, Cicada wins."

"Cisco, your powers aren't what gives you purpose." Peter informs his friend.

"I understand, okay?" Caitlin tells Cisco. "When DeVoe took Crystal away, I was destroyed. But you know what? I'm still here. And so are you. Because you're Cisco Ramon."

"One of the best engineers I know." Peter adds.

"A prodigy hacker." Caitlin lists.

"Not to mention you built a weapon that could stop a speedster." Peter states and Cisco laughs at that.

"And you're our friend." Caitlin says. "You're my friend who went out there and hurt himself today. Just to help me find my dad. And that wasn't Vibe. That was Cisco, and that's the guy I need."

"That cold gun was pretty amazing." Cisco agreed.

"It was stolen almost immediately..." Caitlin reminds him. "But it was pretty great."

"It's painful to get hit with." Peter comments, feeling his stomach where Snart hit him and Barry the first time.

-

Nora was still at Peter's place and was with Frankie as they were just hanging out.

"This is the life." Nora comments. "Seriously, I could stay here forever. No worries, no schrap from Mom."

"Schrap?" Frankie asks, not knowing what that is.

"You know, like all the nagging that someone does." Nora explains its meaning to her. "It's...a future thing. I mean, she acts like she supports me, but what she wants is a boring, quiet daughter who just wants to stay inside all day instead of going out and do anything that might be the least bit dangerous."

"You do know you're describing a parent, right?" Frankie informs her.

"Yeah, except your parents don't keep you away from danger. They encourage you to run into the fight." Nora reminds her.

"Yeah, a decision I or they didn't make easily." Frankie says. "I didn't want these powers at first until I learned there were others struggling like me. That's when I decided to use these powers as a gift."

"And that's what everyone wants to be in the future." Nora tells her. "Every girl in the future wants to be Metalla. You can bend the strongest of steels, you have metal on your suit that you can manipulate to help you fly, a speck of metal is all you need to take down a gang of criminals. You've even rebuilt houses that are destroyed during battles, and even make some people metal origami from leftover parts. Everyone wants to be like you."

Frankie is shocked to how much she has accomplished in the future.

"Even I looked up to you whenever you defeated the newest threat. A bomb in Central City, Metalla can easily find it. A getaway car? Metalla can stop them. Everyone remembers Spider-Man, but you're-"

"Wait, did you just say remember Spider-Man?" Frankie interrupts, hoping she heard that wrong and Nora sees she revealed something big.

"Nora, what's going to happen to my dad?" Frankie asks.

-

Later, everyone is in the cortex when Iris comes in running. They were filled in on a new metahuman who was basically a living rag doll.

Another one of Peter's worst nightmares coming to life.

"Guys, Merkel kidnapped Barry." Iris tells them.

"What?" Harry asks.

"How's that even possible?" Caitlin asks.

"He's got Barry's meta cuffs." Iris explains.

"For the fastest man alive, he's pretty slow." Peter admits. Darts, cold, and and now dolls.

"Who are you calling?" Ralph asks as Iris is calling Nora who's probably back at Peter's place with Frankie.

"I'll ping Barry's cell, see if I can get a location." Cisco says and quickly gets it. "He's in Eaglesham apartments on Simone Ave."

"I don't think he's in the apartment so much as on it." Caitlin comments seeing the blip is coming from the roof.

"Okay, we don't have a speedster, Cisco can't breach, and Crystal Frost is out of commission. We need to come up with a plan to rescue Barry now." Iris commands them.

"Hey, cool it!" Peter tells her, not liking how she phrased Crystal Frost like she's some sort of tool to be used. Not to mention they can sort this out without her yelling at them and bossing them around. "Cisco, think we can use an extrapolator?"

"It's broken." Harry informs them.

"How?" Caitlin asks.

"Long story." Ralph chuckles. "It's not user friendly."

"You're not user friendly!" Cisco yells. "That's plan is a no go."

"Okay, I'll take the Velocity-Spider, Ralph suit up." Peter tells the waistband as he goes to the manikin holding the spider speedster suit.

-

Later, they're all suited up and Peter speeds them off while Ralph screams as they run.

They make it to the roof and see the freakish metahuman walking like he came from the Exorcist movies.

"God, my nightmares are a reality." Peter comments. "Let him go, you living Ragdoll."

"Spider-Man. Not who I wanted." Ragdoll says.

"Sorry to disappoint." Peter says and raises his web shooters. "Now let him go, or you're in for a super whooping."

"Let him go? Very poor choice of words." Ragdoll says and pushes Barry off the edge of the building and Peter leaped down the side of the building to catch him while Ralph got Ragdoll.

Peter Webber the speedster and pulled himself to Barry and used his suit to speed the two to the ground and gets him out of the meta cuffs.

"Whoo. That was a rush." Peter says.

"Wait, what about Ralph?" Barry asks and they look towards the building and see something falling.

"I hope I don't land on my keys!" They hear Ralph scream as he lands and crushed a car.

Peter and Barry flinch, feeling that pain and wonder where the guy is.

"Where's Ragdoll?" Peter asks when they see the man trying to escape his stomach.

"You guys still have those meta cuffs?" Ralph asks them.

-

With Ragdoll locked up in the pipeline, Fox and Harry put their minds together and learned Thomas Snow might be in a Tannhauser black ops site somewhere.

Cisco even had the idea to hack into all of DeVoe's satellites to replace their satellite he destroyed.

"I give you HAL, Robbie, Data, and Colossus." Cisco name's all the satellites.

"Those names are stupid." Harry says.

"You're stupid." Cisco replies.

"But nonetheless, these will be able to help us track the shards of the satellite easily." Harry says.

"This means we can find your father." Peter says with a smile and Caitlin looks hesitant. "Isn't this what you wanted?"

"It is...I..." Caitlin starts and doesn't know what to say.
