The team is looking at the biggest breach in Central City, which just so happened to end up in their labs.

"Pretty amazing, isn't it?" Barry asks Peter looking at the big clue ball of energy.

"There are 52 breaches in Central City and somehow the biggest one of them just happened to end up in our basement." Peter replies in complete shock and yet unsurprised at the same time.

"We need a name for it." Cisco tells them. "It's not exactly a pet, Cisco." Barry tells him. "No, it's a wormhole." He tells them.

"This isn't just a wormhole, it's my way home." Jay tells them and they think if Zoom could use it to get to their world, they can do the same.

"If Zoom uses the breaches, why can't we?" Jay explains and they just don't know how how he does it.

"I mean, we don't know how. Everything I put through, just bounces back." Cisco tells them and Barry gets an idea. "If Zoom is using these breaches to transport people from Earth-2, maybe it takes a speedster." Barry says and speeds to get a running start.

"Is he gonna..?" Cisco wonders, thinking this is a bad idea.

"Yeah, I think he is." Peter answers Cisco's unspoken question as Barry speeds at the portal and is immediately flown backwards.

"Maybe I'm not fast enough." Barry suggests while Peter is regretting not recording that.

"I don't believe your speed is the entirety of the issue, Barry." Peter replies as Stein was thinking the same.

"It might be the breach's stability or lack thereof." Cisco suggests and they agree.

"I'm sorry, I'm lost." May tells them.

"Think if it like a door, and on the second earth, there is a second door. Between that is a hallway that is constantly shifting between other worlds, collapsing in on itself." Peter tries expains and that she understands.

"So we stabilize the door, stabilize the hallway, and then anything or anyone could go through it?" May asks him and they see she's right.

"How's Stein doing?" Peter wonders and they wonder the same.

Upstairs, Caitlin and Iris are working on Stein as his head burst into flames like Firestorm. "He's dropping out." Caitlin says as they attach the Firestorm device on his chest and reconfigure it to steady him.

"This isn't normal. Even from what I've seen about him. Cisco was able to do what he could to re-engineer dr. Wells' original stabilizer to quell the reaction, but we don't know where he got the power source." Caitlin explains to her and they don't know how long it's gonna last.

The team comes back from the basement, to the cortex and Caitlin has an idea to save Stein as Peter had to go back to Mercury labs for work.

"When the particle accelerator exploded, the dark matter that collided with Professor Stein fused with the Firestorm matrix and altered the normal molecular process that occurs within his body. Those highly reactive molecular needed something to bond with in order to stabilize." Caitlin explains and shows them.

"And that's where Ronnie came in." Cisco recaps. "Yes, And now that Ronnie is no longer a part of Professor Stein, the molecules don't have anything to bond with. And the longer he gi s without merging, the more unstable he becomes." Caitlin finishes and they see that they need a replacement Ronnie to save Stein.

"Okay, so how do we do that? Are we gonna make a Tinder app for potential metahumans? 'Cause I'm pretty sure merging with Stein and randomly bursting into flames sounds like the biggest 'swipe left' of all time." Cisco tells her.

"Even if we could find someone willing, Stein can't merger with whoever he wants." Barry informs Caitlin.

"No he can't, but Peter had done some research while at Mercury labs and found two candidates that might be compatible. They were both affected by the dark matter, and were both admitted to the hospital, showing symptoms of gene rearmament mutation. And they both share the same blood type as Professor Stein and Ronnie." Caitlin informs them and they see they need to know who is more compatible.

While They got their first candidate, Peter was working and heard Tina in the hall talking to her assistant. "Remind me to call Richard tomorrow about the shareholders meeting." Tina says when Peter's senses go off and the alarms blazing.

"Applied sciences." Tina says and Peter rushes to meet the intruder before anyone got hurt.

Peter makes it and sees someone walking down a hallway and Peter rushes to stop him. As Peter got closer, intruder starts running and Peter was able to get a look at him.

"Wells?" Peter asks, seeing the man who died last year still alive somehow.

Later the CCPD show up to report what happened. "Detective West, thank you for coming." Tina tells Joe as she leads them to the scene.

"Dr. McGee, this is my new partner, Detective Spivot." Joe introduces them. "On the phone, you mentioned this was a sensitive matter."

"It is, And I called you directly because I've always appreciated your discretion in the past. Dr. Parker was able to see the intruder, and is shocked to what he saw." Tina explains as they approach Peter.

"Peter, can you describe who it was?" Joe asks him. "I can do more than that, Joe. I can tell you exactly who it was." Peter tells Joe and he sees that as help, not knowing who it was.

"Now before you call me crazy, I saw him 100%, no doubt about it. It was Harrison Wells." Peter tells them and they certainly are confused.

"Harrison Wells is dead." Patty informs Peter. "Yes, I know he is, but I know that face. It was Harrison Wells." Peter explains to them and that's surprising to hear.

"I seem to recall the circumstances around his passing were a bit inconclusive." Tina tells them since they couldn't tell everyone he was erased from existence. "Is there any possibility he could be alive?" She wonders and they explain he's dead 100%.

"I met that man multiple times, I know who I saw. The difference was he was running, with no wheelchair." Peter explains to Joe and that's seriously confusing.

"You have full access to the facility if needed. Thank you, Detective." Tina says and leaves them.

"First a shark-man, now a dead man walking." Patty recaps their day. "I'm sorry, a shark what?" Peter wonders, first time hearing this.

"We need to call Barry, get him in here first." Patty tells Joe.

"Peter, can you give us a minute, maybe keep this between us for now and see what you can find out." Joe wonders and Peter does as he asks and leaves them to talk.

Peter comes back to Star labs and heard that the recruiting candidates didn't exactly go so well. "What's being described as a spontaneous energy malfunction erupted last night at Eikmeir Technologies. Wanted for questioning is scientist Henry Hewitt." The news tells them and that happened to be one of the candidates.

"Hewitt's dormant abilities must have been triggered when we attempted the merger." Caitlin tells the team.

"This could be catastrophic." Stein states.

"Yeah, if they're anything like yours, he requires a grounding mechanism to stabilize his volatility. Otherwise, he's gonna go big boom." Peter informs them.

"Yeah, and he's got a long history of violence, according to his police records." Cisco informs them and Peter didn't find any of those.

"I looked at everything I could get into, where did you get records?" Peter asks his friend.

"It was a sealed file. But I hacked into it and look at this." Cisco explains and shows them the list.

"One count battery, two counts aggravated assault, court ordered anger management therapy." Peter reads just the top the list. "This guy belongs next to Ock for crazy scientist."

"He seemed like such a nice guy. We should've waited until you could've been here to see what your senses said, Peter." Caitlin states since he seemed alright at first glance. They're interrupted when Stein is loosing his strength.

"It seems mr. Hewitt's stability isn't the only thing in question." Stein states and needs to lie down as Barry and Cisco leave them.

"Stein is getting worse, and Hewitt is like this because of me." Caitlin says, getting angry at herself. "And now Jefferson Jackson will never come back because of what I said." She tells Peter and he heard about what she said.

"This isn't because you didn't believe in him, Cait. When it comes to a decision like this, nobody can know what the right choice is. I didn't just decided to become Spider-Man. I fought in a illegal boxing match, lost my uncle. Sometimes, great possibilities are planned for us, and at first, we don't see them, because we choose not to." Peter explains to her and she understands what he means.

Caitlin decides to visit Jax at his place of work and Peter decides to go with her. "Let me guess, you don't got car troubles." Jax states seeing the two.

"I came to apologize. I'm sorry for what I said." Caitlin explains to him while walking towards him and Peter's senses pick up a third presence.

"It's fine. Apology accepted." Jax tells her and continues to work.

"Look, we could really use your help save Professor Stein." Caitlin tells him while Peter is locating the source of his senses.

"That desperate, huh?" Jax asks her.

"Our friend, Ronnie, he used to be Professor Stein's other half. He actually helped build the particle accelerator, and when it exploded, he was affected by it too. Ironically, that's how he got the chance to show the world what he was capable of." Caitlin explains and Peter is confused why she called him friend when from what he was told, they were suppose to be still seeing each other.

"And he died saving the city last year." Peter informs Jax entering the argument, leaving his senses until they go off again.

"Wait, he was the guy who flew into the hole?" Jax asks them.

"He died a hero. We're offering you a chance to be one, too." Caitlin tells Jax.

"I never wanted to be a hero. What I wanted was to go to college, but we couldn't afford it. Football was my way in, until that got taken from me." Jax explains to them.

"I never wanted the life I was given either." Peter says and decides if he's going to trust them, he should tell him and reveals part of his Spider-Man suit under his clothes.

"I never wanted this, I never thought of it possible at the time. Until I learned maybe I was given this chance for a reason. I could have just forgotten about these powers, maybe use it on my resume, but I decided to protect others. The accelerator took something from you and it's now giving you something in what you have lost. A chance to be part of something greater than ourselves to protect them and to make sure they don't loose as much as we have." Peter goes on, that being the principal he stands on for becoming Spider-Man. In loosing his uncle, he became a hero he would be proud of.

"We believe you were meant to be a hero." Caitlin says when the lights start flickering and they turn to see Hewitt.

"I've been looking for you, dr. Snow." Hewitt tells them and he tries blasting Jax, but Peter pulls him out of the blast and Hewitt starts absorbing the energy in the room.

"You did this to me! But it's not what you promised, is it?" Hewitt states and they believe its time to run for it while he tries chasing them.

They were able to make it to Star labs and Stein isn't getting better.

"Oh, good you're here. This thing, it ran out, like, 30 minutes ago." Cisco says referring to the device keeping Stein alive.

"His temperature is 142 and rising. He's going into rapid oxidation. We need to find a coolant." Caitlin tells them and it's too late for that.

"I'll do it." Jax tells them and he is ready to merge with Stein. "You said this is a chance for me to be part of something bigger, to help people. That's what I want." Jax says looking to Peter.

"Are you sure? Once it's done, there no undoing." Peter warns him and he agrees to do it. They wake up Stein and place the device onto Jax and hopes that this is going to work as they bring in Stein and they're ready to see if they're compatible.

Jax and Stein touch and they watch the two become Firestorm. "Cool, So I get Grey as my copilot." Jax realizes.

"So when do we get to take this for a test spin?" Jax wonders when they get an alert on Hewitt.

"How about right now? It looks like he's recharging at Central City High school's football stadium." Cisco tells them and the heroes head out to stop him.

At the football stadium, Hewitt is absorbing all the energy as Spider-Man, Flash and Firestorm shows up and evacuate the grounds. "Cisco, cut the power so he can't draw anymore energy." Barry tells them and he's on it and all energy goes out.

Barry and Peter go in to confront him. "Hewitt! You need to stop!" Barry tells him when Firestorm shows up, making Hewitt angry.

"Stein? You chose him over me? That's who I'm supposed to be!" Hewitt states to them. "I deserve the Firestorm matrix!" He then shoots at Jax and he goes flying and Stein starts talking him through it.

"Hey, guys, cutting the power didn't work. It's like the more we anger him, the stronger he gets." Barry states and that gives them an idea.

"That's it, it's like one of those controlled fusion devices. The more powerful they become, the more unstable they become. Make him angry and he'll blow his fuse." Caitlin tells them.

Jax and Barry look towards Peter as he just looks towards Hewitt while smiling under his mask. "My time has finally come." Peter states to them and they know they have the right man to infuriate someone.

"Who's up to a game of catch me if you can?" Peter asks his friends and swings off as they fly/run to follow him.

"Hey, Hewitt, I heard of hot heads, but this is taking it a little too far." Peter quips and dodges his blast.

"You need a hug, Doctor?" Barry asks from behind him and speeds off as Hewitt tries blasting him.

"Come on, Hewitt, give me your best shot!" Jax intimidates and they shoot at each other. Barry and Peter come to a stop and look to him.

"Is that all you got, Hewitt?" Barry asks him.

"I mean, it's no wonder you didn't cut for Firestorm if this is how you fight." Peter quips again and that's getting him angry and he sends a shockwave at them, but it misses and Jax goes in for the final blow and knocks him out.

"That wasn't bad for your first go." Barry comments on Jax and Peter agrees he can do some good.

"Welcome aboard, Firestorm." Peter greets the hero.

Jax and Stein decided to go visit the same friend who helped Stein and Ronnie so they might not see them for a while.

While they were dealing with everything, Jay was in the basement working on stabilizing the breach. "Wow, look at that." Peter says seeing the portal is finally stabilized.

"Shall we see if it works?" Peter asks and grabs a first aid kit and throws it through the portal and it went through.

"It works!" They all say and are happy to see they have their own way to Earth-2 and back now.

"I guess this is it, huh?" Jay says since now he can go home. Back to where he belongs, but even though he doesn't trust Jay completely, Peter knows that they need him.

"Well, we still need your help with the breaches and Zoom is still out there." Peter says and Jay ageees to stay and help for a while longer.

Barry was in his flash suit speeding and stops outside Jitters to get time to talk to Patty to ask her out. When he gets attacked by a giant man shark. "Zoom wants you dead." The shark tells Barry when he suddenly gets shot by someone with a gigantic gun and he walks away.

Barry speeds up to him. "Who the hell are you?" Barry asks as the man removes his hood to show the one person he thought he'd ever see again...Harrison Wells.
