It is official to say that they cannot leave Harry to stay up past 9:00 as he's come up with the most craziest plan ever heard.

"This is gonna give us the edge we finally need to be smarter than DeVoe. Or me to be smarter than DeVoe, actually." Harry says as he shows them a thinking cap blueprints. "This is an intelligence booster. You put this thing on Dibny here, and even he would be able to understand the point source construction. You put it on a real genius, I'll be able to out think the Thinker." He then takes a drink from his coffee.

"You know what, I'm not sure this thinking cap is the best idea you've ever had." Cisco tells him.

"It's an intelligence booster." Harry corrects.

"It looks like a thinking cap." Cisco states.

"You don't like it, blame yourself. You gave me the idea." Harry informs him. "You're the one that said DeVoe planned all this just like Thawne in order to stop Barry. And Parker said that DeVoe became the Thinker the same night Allen became the Flash, and so I hacked into security footage of that night to see what you saw." He tells them and shows DeVoe getting struck wearing a thinking cap. "This is why he's so smart. DeVoe boosted his intelligence with neurochemical engineering powered by the dark matter from the particle accelerator explosion. And if we build our own, we can do the same."

"Just to clarify, Harry, you wanna blast 10 billion joules of dark energy into your brain?" Peter asks.

"I've harnessed power from the accelerator before, and I can do it again." Harry promises.

"But reengineering your brain's neurochemistry-" Caitlin was saying when he stopped her.

"DeVoe did it. So can I. How many more metas have to die before we finally stop DeVoe?" Harry asks.

"Not me." Ralph says as he raises his finger. "I say we go for it. Right?"

"Won't harm anyone to explore it." Peter agrees.

"Yeah, I'm onboard." Caitlin agrees.

"No, this is way too risky." Cisco tells them.

"Of course it's risky, but if we succeed, we will save the lives of the four remaining bus metas, including a member of the team." Harry says, pointing to Ralph.

"You're talking about intense amount of dark energy going right into your brain, right into that cap that turned a Mac and cheese loving pacifist into a homicidal maniac. You put that cap on, what's it gonna do to you?" Cisco asks.

"I've run the numbers dozens of times. The math and chemistry check out. I can do this." Harry promises.

"I don't think you can." Cisco replies.

"I can with your help." Harry states.

"Not this time." Cisco tells him. "All right, lets keep coming up with more ways to solve this." He says before leaving the room.

"Just so I'm clear on this, someone finally came up with a way to stop this La-Z-boy riding lunatic and we just might do it?" Ralph asks.

"To be fair...he does raise a valid point." Peter admits while a memory floods his mind. "There was someone else who tried to enhance his intelligence...it didn't end well."

"Who?" Barry asks.

"Otto Octavius." Peter says as he remembers how he was once an amazing scientist...before the arms. "He developed an inhibitor chip to help him control his arms, that also helped enhance his thinking capability. And then he went crazy. So, all we have to do is be careful, and not turn Harry into our next animal based villain."

"Yeah, what is it with your enemies and being animals?" Caitlin wonders.

"Yeah, Rhino, Vulture, Scorpion, dr. Octopus, even Kraven the Hunter." Miles adds on and they all look confused. "What? I was Spider-Man's biggest fan before I became the ultimate Spider-Man, remember?" He reminds them.

-

Then later there was an attempted bank robbery that was failed when the man's powers stoped working suddenly.

And apparently the powers are even hotter than Mick's gun and they learn that he's not a bus meta, but an original meta.

And his powers vanished.

"So, I can think of a couple of ways this might have happened." Caitlin tells them as they all come back to the cortex. "If this Eric Fry metastasis solar radiation to create heat, we could put him in the dark to de-power him."

"But it was still broad daylight." Joe adds.

"Okay. Maybe his internal biochemistry has been altered to create its own internal thermal combustion and he just ran out of fuel." Caitlin guesses.

"So, if this guy's not one of the bus metas, that means there's still three more out there before DeVoe gets to me. So, I'm safe. Safer, I'm safer." Ralph states.

"These are innocent people, Ralph." Barry reminds him.

"I'm innocent. I'm still gonna get terminated." Ralph says. "Oh my god. I'm Sara Conner."

"Eh, I'd say more John Conner, and we're the Terminators saving you." May corrects him.

"I'm gonna go back to my room. Get some comfort food." Ralph says and leaves.

"The way I see it, Fry walks into the bank with his fire powers, meets this other guy, and then his powers are gone." Cisco says as he looks to the footage. "Coincidence? I think not."

"So you think this guy did something to Fry?" Caitlin asks.

"I think we can ask him some questions." Cisco says.

"I interviewed every eyewitness in the bank. Nobody knew who he was." Joe tells him.

"Okay, Cisco, crosscheck the deposits from today with the list of witnesses." Peter offers and Cisco's on it.

"Everyone on the list checks out except a Mattew Kim, an EMT out of Central City General." Cisco tells them.

"Barry, let's go ask some questions." Joe says and they leave.

"I'll get ready for backup." Peter says as he starts changing into his spider suit. "Cait, try and see if you can figure out how this power stealing of his works. Cisco, use the satellite to scan the city for the dark matter. Miles, hit the streets while I'm busy. Frankie, get your homework done." He tells the rest of the team as he leaves.

-

Joe and Barry went to talk to him which ended with Peter and Barry trying to stop him from getting away.

Barry speeds to stop him and Peter shoots a web which causes the two to feel funny before he runs off.

"Go get him." Joe tells him and Barry tries to run, but he just ends up jogging.

"I lost my speed." Barry says, completely confused.

"Guys?" Peter asks for their attention and they look to see his hand is vibrating. "We've got a serious problem."

-

They return to Star labs, and Peter is running around the labs using Barry's speed that turned red and bright blue like his old outfit and he comes to a stop.

"Okay, that's one of the best feelings I've ever felt." Peter admits as he catches his breath.

"This is fun." Barry says as he's balancing himself upside down with no blood rushing to his head.

Caitlin then comes in with results with what happened. "I've run every test I can think of. EKG, cellular regression synthesis, brain chemistry, and dark matter confirms it. Your powers have been swapped."

"How could this be possible?" Joe wonders.

"Barry's connection to the Speedforce, his speed, the dark matter, it all been transferred into Peter. With Peter, his radioactivity, his muscle endurance, strength, spider abilities, even his bone density, all have been transferred into Barry." Caitlin tells them.

"Can we...reverse this?" Peter asks.

"I don't know. I can try." Caitlin promises.

"So, Matthew Kim isn't just removing DNA. He's transferring it to anybody he touches." Joe sees.

"He's not getting rid of metas. He's creating new ones." Ralph adds.

"That's not the only thing. Guess who's got an apartment just a block away from the 405 bus line and rides it every day to get to work?" Cisco asks.

"So Matthew is our bus meta." Peter adds.

"Which means DeVoe is gonna be after him." Barry finishes. "And if he gets him, he can take away all of our powers."

"Unless we get him on our side first." Joe states. "Then he can remove the powers from DeVoe."

"That could possibly work." Caitlin agrees with him. "Matthew's abilities work by melting down the highly concentrated bonds between DNA. That makes them totally pliable so he can extract them and infuse somebody else with the same meta DNA."

"Melting Point." Cisco says, naming him.

"Doesn't that mean somebody has those fire powers now?" Frankie asks.

"She's right. Meaning we need to find them as well as Matthew." Peter agrees with her.

"And I'll find a way to reverse this." Caitlin says as she leaves.

"So, what do we do?" Peter asks as he turns to face Barry only to see he's gone. "Barry?" He calls out for him.

"Up here!" Barry yells and Peter looks and sees he's stuck on the ceiling. "This is nice."

"You can't get down, can you?" Peter guesses.

"No, I can...I'm just choosing to stay up here. It's a long way down." Barry lies.

"Okay." Peter says as he walks off, not using superspeed and leaves the man hanging.

"Wait, just out of curiosity, how would I get down?" Barry asks as he leaves. "Peter? Peter!"

-

Later, Caitlin talked to Cisco about helping Harry with his thinking cap, Peter was able to get Barry off the ceiling and now Barry's teaching him how to run.

Peter was on the treadmill with Barry monitoring his speed.

"Hey, Peter, you wanna slow down?" Barry asks, seeing he's going too fast.

"How the hell do you slow down?!" Peter asks as he's freaking out.

"Just gradually ramp our speed down, otherwise, you'll-" Barry was explaining when Peter tripped and ran into the boxes.

"That hurt." Peter complains as he gets up with Barry's help.

"You sure you're okay?" Barry asks as he gets up.

"Yeah, I'll be fine." Peter promises when the alarms go off.

Peter accidentally speeds off and leaves Barry to run back.

"What's the situation?" Peter asks as he's the first to arrive.

"Baldwin Tower's on Fire. CCFD's responding, but there's people on the top floor they can't reach." Cisco tells them as Barry runs in.

"Okay, Caitlin, get Crystal caught up. Cisco, Miles, and Ralph, evacuate everyone." Peter tells them.

"Not a chance." Ralph tells him. "This could just be a trap for DeVoe to get us out in the open." He states while eating food.

"Hey, I think we got a bigger problem." Cisco interrupts. "We don't have a Flash or Spider-Man."

Miles clears his throat, getting Cisco's attention.

"An experienced Spider-Man." Cisco corrects himself.

"Actually, we technically do." Frankie says and turns to the heroes.

"No, we can't do anything with these powers swapped." Peter states, knowing that they can't.

"We could use the help, Peter." Caitlin tells him and Peter looks at the Flash suit.

"I'm taking this to my grave." Peter promises and speeds his Spider-Man outfit on Barry and the Flash outfit on him before he speeds off with Barry inhand.

"This should be interesting." Cisco says, wondering how this will turn out.

-

Barry and Peter come to a stop outside and see the large fire outside the building.

"Oh boy." Barry's muffled voice through Peter's mask mumbles.

"Okay, what's the plan...? Okay. Use my monitors, scan for people, think what you want it to do." He tells him and Barry finds civilians.

"This is seriously weird. Okay, there are five people on the 14th floor. You just have to get them out of there as fast as you can." Barry tells him.

"Okay, I do that, you get the foam webbing ready to take out the flames." Peter says as he speeds up leaving Barry there, confused to how to get up there.

"Okay, so how do these work?" Barry asks as he looks at his web shooters and moves his fingers to push the button and it shoots out a web to the 15th floor window and drags him into the flames. "Okay, that was not the best plan."

Peter finishes evacuating everyone and sees Barry's gone inside. "Oh, boy." He whispers before speeding in.

Barry's trying to figure out how to switch web settings as he has a dozen settings. He chooses one with a picture that looks like foam-webs and then pushes the shooters start releasing taser-webs.

"That is the wrong setting." Barry says when Peter speeds in.

"Oh, this is bad." Peter says, seeing the building falling apart.

Barry's head starts buzzing and he looks to see the ceiling falling on them. "Look out!" He moves Barry out of the way and catches the falling building floor piece.

"Okay, let's try a wind tunnel." Peter says as he starts to spin his arms around and he's going the wrong way and it's getting worse.

"Go in the other direction!" Barry tells him as he's struggling to get his hands free of the floor as Peter changes directions and the fire goes down.

"Okay, that was good." Peter says as he turns to see Barry struggling. Peter speeds at him and pulls him free and lets it fall on the floor.

"Thanks." Barry tells his friend when they look at his fingers to see the floor pieces are still sticking to his fingers.

-

"There's still a little bit of irritation in your lungs from all the smoke you inhaled, Peter, but you should be good to go soon." Caitlin tells him as the two returned to the labs and changed out of their suits.

"That's good to know." Peter says. "Luckily, we were able to save everyone. But I don't think I can be the team speedster."

"Yeah, I agree. And we need to find Matthew Kim and whoever he transferred Eric Fry's powers to." Barry adds on.

"How close are you to reversing this?" Harry asks Caitlin.

"I don't know if I can." Caitlin admits.

"What?" All three of them ask.

"I was up all night trying every conceivable solution. Dark matter splicing, pattern DNA cloning, even regrowing meta enhanced stem material on a cellular level. Nothing will work. I can not replicate Melting Point's powers." Caitlin breaks to them.

"So unless we find Kim and reverse what he's done..." Barry says.

"Spider-Man and the Flash have new identities." Caitlin finishes.

The team all separate and Cisco goes to agree to help Harry with his thinking cap.

Caitlin finds Peter sitting in a chair while staring at the two mannequins of Flash and Spider-Man and sees his sad face.

"You doing okay?" Caitlin asks him.

"No, not really." Peter admits looking to her. "I never thought I was destined to be anything more than just Spider-Man. Now it feels like DeVoe created this new meta just to make us go crazy."

Caitlin walks up and places her hands on his shoulder and drops down to loosely hug him. "Where's Barry?" She wonders.

"Miles offered to teach him a few tricks I taught him." Peter replies.

"The student becoming the master now?" Caitlin jokes and Peter laughs at that when the alarms go off and they break apart and see what's happening. "We found who has Fry's missing powers."

They see someone is starting to burn a area where the police have already made it.

"The satellite is tracking the same intensity as the bank robbery, so.." Harry says, meaning it's him.

"Who's that?" Ralph asks as they see Matthew Kim is also there.

"He's gonna try to steal his powers." Harry says.

"All right, lets suit up." Cisco tells Caitlin.

"No, you guys stay here. Me and Barry need to get there and hopefully get back to normal." Peter says and Barry agrees. "You ready?"

"Miles taught me how these web shooters work. Let's see if we can do this." Barry says and Peter flashes them back into their suits.

-

The new metahuman starts throwing fire at the police cars and the officers.

"This is a mistake!" Kim shouts. "You need to stop this."

"Oh, I just got going, pal." The new Fire metahuman says as he recognizes Kim. "Wait, you're that hero from the bank, aren't you?"

"I am. And I need you to stop this." Kim tells him.

"So you can take my powers like you did his? You just gave them to me."

"What are you talking about?" Kim wonders.

"You didn't know that? When you took powers from him, you have them to me. And now I'm gonna get what he couldn't. Money!" He says and shoots fire in his direction that gets interrupted by a flash of red and blue lightning and Peter stops and Barry is waiting to handcuff him.

"I think you've done enough for one day." Peter tells him.

"We'll take over from here." Barry promises and they both approach him.

"Listen buddy, we've been having a bad day. So how about we end it?" Barry asks.

"That sounds fun. 'Cause I was just warming up." He tells them.

"Fire puns?" Peter asks. "Even I find that stupid."

Before he could flame up, Barry webs him with new ice webbing that freezes upon impact. But that only works for a second when his flame burns through it and sends them both flying backwards.

"Okay, that failed." Barry says as he gets back up. "Any other ideas?"

"What if I create a vortex like you did with Fallout?" Peter asks.

"The lack of oxygen will extinguish the flames." Barry understands and Peter starts to run around him, but that seems to make things worse as a thermo cyclone is created.

"Guys, any other ideas?" Barry asks, seeing it's failing and Peter keeps it up, hoping it works.

"Peter, use your speed to draw enough water from the Central City bay, extinguish the blaze. Allen, while he does that, use the ice webbing and just piss him off." Harry tells them.

"Pissing people off is what Spider-Man's known for." Barry mumbled.

"Hey! It may be the truth...but, hey!" Peter complains and speeds off and follows Barry's instructions to how to run on water.

While he does that, Barry runs around and dodges his attacks while shooting ice webbing at his face, legs and arms to annoy him.

"You're becoming a pain, spider!" Fire metahuman tells him.

"Come on, man. At least say something original." Barry complains when he turns and sees Peter has made the tidal wave they need and Joe evacuates the cops and at the last second, Barry shoots a web to get him out of the way as the water crashes on him.

While he was down, Peter speed in and handcuffs him.

"I have to say...you're all burned out." Barry quips and Peter looks to him with an eyebrow raised. "What? Admit it, you were thinking the same thing!" He states and Peter was, but he wasn't gonna admit it.

-

"I'm so sorry I did this to you." Kim apologizes to them as they brought him to Star labs to fix their powers. "I thought I was cleaning up the city, but I was just making it worse."

"Well, we stopped him. He's in iron heights, and that's all that matters now." Barry says.

"You sure you both want to do this?" Kim asks them both.

"Well, gonna be frank, I am gonna miss being able to rush around and get everything done. But...I miss my powers." Peter says, knowing he was destined to be Spider-Man, not the Flash.

"And being as light as a feather and as strong as steel is fun, but I miss my powers. Not to mention, I'm afraid of heights and can't stand swinging. I don't know how you stomach it." Barry admits and Peter laughs.

"Ready?" Kim asks and he touches their shoulders.

"That's it?" Joe asks.

"You guys okay?" Cisco asks. "How do we know it worked?"

Caitlin picks up a pen and throws it at Peter who catches it instantly before it could hit him. "Spider-Man's back in action." She smiles.

"Flash?" Harry asks and Barry speeds around the room and stops.

"I feel great." Barry says.

"Well, that's the last time I'm using this power. The city was almost destroyed because of me." Kim says as he starts leaving.

"But you had no idea that would happen." Caitlin replies.

"Yeah, don't be so hard on yourself, pal." Ralph agrees.

"I thought I was chosen for a higher purpose. This can't be it for me." Kim states.

"Maybe you were chosen for a bigger one." Barry tells him.

"Clifford DeVoe, he isn't going to stop until he gets you and everyone. We could use your help." Peter tells him.

"How do we start?" Kim asks.

"I'll give you the tour." Cisco says and leaves with him.

"That was some nice moves you had out there, swinging and actually combining the webbing? Ingenious." Peter admits to barry.

"Says the man who created a tidal wave on his first day." Barry replies. "What do you say? You wanna do one last training session?"

"Sure. Why not?" Peter agrees, wanting to learn how he did that.

While they did that, Harry and Cisco finished the thinking cap and got the last two names of the last bus metas.

Janet Petty and Edwin Goss.
