You know that strange feeling you get when you don't know when you're dreaming but you know you're in reality?

Well, today would count as one of those days when you see a dead man walking in front of you reading a book about himself.

"Very strange to be holding your autobiography, especially when you didn't write it and it's not about you." Harrison Wells tells them and drops the book.

"Caitlin, Cisco, Peter, meet Harrison Wells of Earth-2." Barry introduces them to each other.

"Oh, we know each other." Peter states looking at Wells.

"You're the guy who tried stopping me at Mercury labs." Wells realizes.

"So let me get this straight. You're the doppelgänger of the man who murdered his mom and is responsible for both Ronnie and Eddie's deaths." Cisco recaps, but Caitlin interjects.

"To be fair, he's not even the doppelgänger of the Dr. Wells that we knew, because his body had been taken over by Eobard Thawne." Caitlin defends and Wells didn't follow any of that.

"I'm my own man." Wells informs them. "I had nothing to do with the murderer of your mother, or your friend Ricky." He states to the team.

"His name was Ronnie." Peter corrects Wells.

"Him either." Wells states.

"You told me you had some proof on your identity?" Barry asks and Wells shows the device they threw through the portal to see if it worked.

"This could be mine, but I want to run some tests." Caitlin tells him and Cisco leans in to Peter.

"Your senses revealing anything?" Cisco wonders.

"Actually, this is strange, but my senses are calm around him. I think he's safe." Peter states and Cisco is shocked.

"He even saved my life last night." Barry tells the team and looks to Wells. "Question is why? I'm guessing you didn't hop between dimensions to meet Spider-Man and the Flash." He says to Wells.

"No, that's exactly what I did." Wells corrects Barry. "I came here to help you to stop your greatest threat."

"Yeah, that's what they all say. Just before another crazy showed up." Peter states since it is a regular thing he's told.

"Well, right now, the latest crazy is Zoom. And I see you've already heard of him." Wells says seeing their faces to his name.

"He's been trying to kill us for some time with your metas." Peter tells him.

"Well, they're the symptoms. Zoom's the plague, one that has infected my world, and now he's coming for yours." Wells warns them and they see he's here to help.

"What do you know about Zoom?" Barry wonders.

"Everything. I created Zoom and helped cause the destruction of all of New York City, including the Spider-Man of my world." Wells answers and explains how he's going to help them stop him. But Peter was shocked to hear he isn't the only Spider-Man in the multiverse.

"Yeah, Well, were batting a thousand against these breachers." Cisco tells Wells as he is looking over Peter's Spider-Man suit.

"You're barring a thousand, Crisco?" Wells questions him. "What's your sample size? Ten? Less? Zoom is obsessed with speed. He will never allow there to be another speedster on any earth, and he is gonna keep sending these metas here, over and over, all with the same goal. To kill the Flash and Spider-Man." Wells informs them and they see they need to hear what he has to say.

That is until Joe comes in and sees him, and immediately tries shooting him. Luckily, Barry was fast enough to stop the bullets and Peter webs the gun port so Joe doesn't try shooting again.

"Joe, drop the gun." Peter tells the cop.

"How is he still alive?" Joe asks while walking towards Wells and Barry keeps him back. "How are you still alive?" Joe asks Wells.

"I don't know, because you missed?" Wells asks and that isn't helping and Barry takes Joe out to talk with him alone.

"We know someone who can verify everything he's saying, you know." Caitlin tells Peter and Cisco, and they know she's referring to Jay. Cisco and Caitlin go to find him as Wells goes back to looking over Peter's suit that's on the manikin display.

"You design this yourself?" Wells asks the spider hero.

"Yeah, with help from a friend to give it some new features my previous suits never had. Facial recognition, heat readings, a few web attacks. Some being web grenades, impact webs, some trip mines, splitter webs, a few more." Peter tells the features and Wells wonders why he's telling him all of this.

"Why do you trust me when the others don't?" Wells wonders, even though he knows the whole killing their friends part. "My doppelgänger must've taken someone from you."

"My senses seem to tell me that you're not a threat. That you're here for a good reason." Peter tells him since in the past, his senses warned him every time Wells was in the room, even with Jay. But with Wells, they're telling him he's a good man.

As they're talking, they get an alert on the computers that a bank is being robbed and he leaves to stop it.

-

As Peter reaches the bank, Barry meets him there and they see a woman wearing a mask only covering her eyes. "You got our attention." Barry tells her and she sees the two of them.

"Flash. Spider-Man." She greets them and blasts a flash of energy at them that they easily dodge and she smashes the ground and sends people flying. As they're keeping the people safe, she makes her escape.

-

"Her name is Dr. Light." Harry (Cisco named him that earlier) explains and shows them everything about her from a flash drive he had on him for some reason.

"A small time thief on my Earth until exposure to the dark matter from the particle accelerator and bacame a metahuman with the ability to derive power from Starlight." Harry tells the team as Caitlin went to find Jay.

"And stars having a temperature of 5,300 degree kelvin and a blinding luminosity, I have a feeling she doesn't go flashing people. Double entendre not intended." Peter tells them.

"Obviously Zoom bought her here from your earth like the others." Barry states as Harry takes a bite out of his food Peter got him.

"And now that we know that, we can use that to help us." Harry tells them. "By capturing Dr. Light, use her to lure Zoom here." He explains when Jay and Caitlin enter the room.

"You are insane! We are not luring Zoom anywhere!" Jay states to Harry as they all look toward him.

"Apparently, they know each other, and Jay is not a fan." Caitlin explains to her friends.

"Like everyone else, I assumed Earth-2 Flash was dead. Why am I not surprised to find Jay Garrick here, still alive and in hiding a full universe away from Zoom." Harry asks Jay.

"I'm not in hiding. Zoom nearly killed me and stole my speed before the singularity pulled me here." Jay informs Harry and that raises some red flags in Peter's head since Jay said he didn't know how he lost his speed.

"Well, whatever the case, in your absence, Zoom has only gotten more powerful, faster. Barry, Peter, you two have to defeat Zoom now while there's still a chance." Harry tells the heroes and Barry is still questioning on trusting this Wells while Peter is questioning on trusting Jay.

"No, this isn't the time to be reckless. We don't even know why Zoom sent Dr. Light here. She's a thief, not a killer." Jay informs them all.

"Zoom can make people do things out of character." Harry tells Jay. "Thief or not, she'll kill you both." Harry warns the heroes.

"All right, look, we can decide what to do with Light later. First we need to find her." Barry tells them and Harry just takes his drink and gets on it.

Barry was asking Cisco how he knew about Dr. Light and Cisco tried changing the subject and gets the satellites searching for her light.

"I'll go to the CCPD, see if Joe has any leads." Barry says and leaves to do that. "Let's try keeping them apart until I get back." Barry tells them regarding the Earth-2 visitors.

"I have a sense that won't be a problem." Peter states to him.

-

Later, Cisco goes into his workplace and sees Harry working in there, researching everything about Harrison Wells while listening to music. "Hey, Harry. Come inside. Use my workroom. Use my computer! I don't care!" Cisco says, sarcasm on every word.

"Thanks." Was Harry's only reply.

"You and Wells prime have very different taste in music. His were better." Cisco comments on his music.

"This Harrison Wells and I are very different but similar in some respects." Harry says looking over everything. "I see he made almost the same mistake I did with the particle accelerator."

"He did a lot for terrible things, and none of them were by mistake." Cisco tells him and Harry stops to ask what Wells did to Cisco and he doesn't want to tell anyone about his powers still.

"Well, here's the deal. You don't have to like me. I don't like you, your friend has a sense that says that I'm not here to harm anyone. If you don't want to trust your friend, that's on you, but you have to work with me to stop Zoom and Dr. Light. Can you do that?" Harry asks Cisco and he agrees just for now.

What Cisco didn't know as he leaves the room, Wells was hiding his watch to scan for metas and it went red, meaning there's one around. More specifically Cisco's a metahuman.

-

"Harry's starting to get on my nerves." Cisco warns the team as he enters the cortex.

"The silent alarm just went off at the Bank of Central City." Caitlin warns them as it comes up on her screen.

"That has to be Dr. Light." Peter says and goes to grab his mask and gets into his suit.

"What do we do if it's a trap?" Barry asks Peter, wondering if he has a plan.

"I'll get the people to safety, you corner her and make sure she doesn't escape." Peter tells him as he places his mask and runs a quick diagnostic to make sure all systems are working.

"Barry, trust me, Dr. Light is not a killer. You can talk to her." Jay tells him and the irony is that Peter doesn't trust him.

-

Barry rushes them there and Peter gets the people to safety as Barry runs into the vault. "Looking for this?" Barry asks, referring to the cart of money.

"We know Zoom sent you here to kill us. Good news, you don't have to do that." Barry tells her, following Jay's advice.

"Not if I can get out of town with that cash." Dr. Light tells him.

"Then what's the plan? Zoom's not gonna like that you ditched him, right?" Barry asks her. "My friends and I can help you." He promises.

"Nobody can protect me from Zoom." She tells him and gets ready to fight him.

"All right, why don't we take it down a lumen, have a normal conversation, all right?" Barry asks her and she calms down he removes her mask.

Barry then sees the face of his ex, Iris' coworker. "Linda Park?" Barry asks her.

"How do you know my name?" She asks before realizing her mistake and blasts a flash of light into the room and leaves. Peter comes in, just missing Linda leaving and sees him looking around.

"Flash, you okay?" Peter asks while helping him stand.

"I can't see." Barry tells him and they see that's a problem.

-

Peter was able to make it to Star Labs with a blinded Flash as Caitlin and May give him a check up. Peter already explained the Wells situation to her a while back.

"I still can't see. How long is this gonna last?" Barry asks the doctors.

"You're suffering from solar retinopathy." May explains to him.

"Your retunas are severely damaged." Caitlin tells him. "You're lucky you're not permanently blind."

"But from what I can see with your rapid regeneration abilities, your sight should come back with time." May explains to Barry.

"6.25 hours by my estimation." Harry helps her out and she agrees with him.

"All this could age been avoided if you just stopped Light instead of chitchatting with her." Harry tells Barry.

"I have to agree with him on that one, Barry." Peter agrees with Wells.

"She caught Barry off guard." Jay tells the two of them.

"He's the fastest man alive. How could she possibly do that?" Wells asks him.

"Because Light looks exactly like my ex-girlfriend, Linda Park." Barry explains and that's confusing to how Zoom knew that.

"So that's why Zoom sent her here. Because he knew you'd hesitate." Harry tells Barry.

"But how could Zoom possibly know she was your ex?" Peter questions, still seeing they're still missing something big.

"It doesn't matter, this is why Barry has to act now before he sends another double from Barry's life." Harry states to them, and Peter still thinks Wells has the right idea.

"All right, right now, I'm more worried about Linda. When I saw who was under the mask, I don't think she knew she had a doppelgänger." Barry explains to them.

"The first thing Atom Smasher did was find and kill his doppelgänger." Cisco reminds them.

"Light's not like Atom Smasher." Jay tells them.

"You know, I'm starting to question your intelligence." Peter tells Jay since he seems more innocent that a two month old child, especially when he says he's been Flash for two years. He should know people can change easily.

He himself learnt that from experience.

"We should keep an eye on your Linda." Wells tells Barry and he offers to go protect her and as he's walking, trying to find his way out.

"You can't do anything, until you have your sight back." Peter tells his friend and puts his hands on the railing so he doesn't trip over himself.

"I'll keep an eye out on Linda. You guys do what you can to help him see if you can speed up the process maybe." Peter offers and begins leaving when Caitlin offers to go it's in case he gets injured.

Iris comes in as they leave and sees Wells. "You look just like him." Iris comments seeing him alive.

"I'm guessing my counterpart did something to offend her as well?" Wells asks Cisco.

"Her fiancé died because of him." Cisco explains and that is explication enough for him.

-

While Cisco was helping Barry on his date with Patty, Caitlin and Peter were camping out in the Star labs van. Caitlin comes back with coffee for the two of them.

"Classic stakeout fuel." Caitlin comments on their drinks and gets back in the van. "I find it strange how you're somewhat addicted to this Spider-Special." She states to him.

"What can I say? They make my name taste good." Peter comments and Caitlin laughs at that and Peter realizes they're alone, maybe he should ask her something.

"What are your thoughts or Harry and Jay?" Peter asks her and she's confused by that question.

"Why, What are your senses telling you?" Caitlin wonders, since she trusts his senses as much as he does.

"It's just...Jay claims to be a hero, but my senses like to say differently. Harry claims to be here with the focus on wanting to help us stop Zoom, and my senses believe him. And the way Jay acts like being a hero is actually new to him after he said he's been doing this for two years. He believes that people can't change from petty thieves to killers. I mean, I learned that Otto was capable of that before he murdered someone, and constantly tried killing me." Peter explains and that's not even everything he's seen.

"Maybe if you had a chat with Wells, maybe that'll clear everything up." Caitlin tells him and Peter sees that's a viable idea since he might be telling the truth. At least more than Jay will.

"I wish things were the same. Before the accelerator, before all of this time travel, multiverse, everything. Back when my biggest concern was some psycho with four metallic tentacles." Peter explains and she understands how he's feeling.

"Well, you should know by now, I trust you completely. You say Wells can be trusted, he can be trusted. If you say to stay clear of Jay, I won't be in the same room alone with him." Caitlin tells Peter while placing her hand on his.

"Good. I wouldn't know what I would do if you got hurt on my watch." Peter tells her and she begins leaning in, Peter sees her leaning in and decided to go with it and leans in himself when his senses go off. Dr. Light is here.

Peter grabs Caitlin as the truck starts spinning and Peter uses his powers to hold them on the ceiling as the car tumbles and crashes. Linda sees them knocked unconscious and heads inside. What she didn't know, Peter was faking it and grabs his mask and heads in after her after checking to see if Caitlin will be okay.

Light makes it inside and sees her doppelgänger. Before she could do anything, Peter comes swinging in and sees dozens of people in danger.

"Everyone, get out of here." Peter warns them and they all start leaving, but Light keeps Linda.

"No, no, she's leaving with us." Iris tells her.

"What do you want from me?" Linda asks and Light raises her hand.

"Your life." She tells her when Peter webs her hand and pulls it from Linda's direction.

"I've never killed anyone before, but the idea is warming up to me, Spider-Man." Light tells Peter as she gets her hand free of his webbing.

"Do we seriously have to go through the whole fight, when we know my flexibility will help me get away from your blasts, we both know I'm eventually gonna knock your lights out." Peter asks her and she looks at him angry at that quip.

"Full disclosure, that was a complete accidental quip." Peter tells her as Iris gets Linda out and te two enhance continue to fight. Peter webs her face and pulls off her mask and she sees she can't stop him and sends another blast of light that Peter quickly dodges and sees she used it as an opportunity to escape.

-

Peter and Caitlin makes it back to Star labs where Caitlin and May are checking up on Peter to make sure they're okay.

"Caitlin, Peter, you two okay?" Barry asks as he got his sight back during his date with Patty.

"Yeah, I'm fine. Light didn't put up a fight, though. Was able to get a few punches in, but Iris was able to get Linda to safety." Peter tells him as Caitlin sees he's good to go.

"Peter, I'm sorry, Dr. Light's never tried to kill before." Jay apologizes and now Caitlin sees what Peter was talking about in the car.

"As I've been trying to tell you, you cannot reason with someone under Zoom's influence, and if it weren't for Peter, a innocent life would've been killed because of you, Garrick." Harry tells Jay. "This whole thing is because of you. He doubts himself because of you, at least Parker knows what he's doing and doesn't listen to you. These heroes are an actual team, they can do what you could not. They can stop Zoom."

"I spent two years hunting Zoom." Jay defends himself.

"Wrong! Zoom hunted you! You even got our Earth's Spider-Man killed in your attempts of running from him. You spent the last two years of your life running, running from Zoom." Wells tells him.

"Zoom would have killed me just like he will kill Barry and Peter if you lead them down this path!" Jay tells him.

"No, because they are nothing like you. They run towards the danger, not away from it, because they're not cowards." Harry tells Jay, and Peter senses he's about to punch him and webs his hand before he could hit Wells.

"Enough!" Barry tells them and Harry leaves in a huff.

Peter decides to follow him to Cisco's workshop.

"You were pretty hard on Jay in there." Peter tells him.

"Maybe you should be hard on Jay, Parker." Harry tells him. "I've seen what you and Allen can do, I've calculated how fast he can run. He should be teaching Jay, not the other way around."

"You said he knew my doppelgänger?" Peter asks Harry.

"I never learned who was under the mask. Nobody learned, it could've been you, could've been some random person. Doesn't matter since when Jay asked him to help, he ended up destroying all of New York City. Zoom tried stealing some alien that was being experimented on at Oscorp and it spreaded like a parasite. Spider-Man was lost in the fight, leaving the King of the Symbiotes in his place." Harry explains to Peter and he's shocked that's what happened in an alternate reality, and that Venom's species actually won.

"Look, I know you're here for some good reason, but Jay, I don't think he can be trusted. My six sense, I don't know if my doppelgänger has it, it's a warning system of sorts. It tells me you're a good man, but constantly tells me to stay clear of Jay. So I'm with you, because I know you can be trusted." Peter explains to Wells.

"Well, then you can believe me when I say you and Allen can take care of Zoom, you and Allen know how to work together, all we have to do is capture Dr. Light." Harry tells him and Peter remembers the mask he took.

"What if we were able to track her with the mask?" Peter asks Harry and he looks to Peter intrigued.

"You have Dr. Light's mask?" Harry asks him.

-

Peter brings the mask in and shows it to Harry.

"How did you get this?" Harry asks Peter.

"I was able to snag it on a web when I was fighting her, when she tried killing Linda." Peter explains to him.

"You know how to use the mask to track Light?" May asks Harry, not seeing how it's possible.

"Yes, I do. All we have to do is give it to him." Harry explains and looks towards Cisco. "You have powers." He states and shows his watch.

"I developed this watch to detect metahumans." Harry says and raises the watch to Peter and it doesn't go off, which surprised most of them but it makes sense since he isn't a meta. Harry brought it to Barry and then it goes off. Harry approaches Caitlin and, of course, it didn't go off. "You never got an alert on your phone. You never reprogrammed the satellite, and this is why." He says and raises his watch and it goes off alerting a meta.

"You have powers?" Peter asks his friend and wonders why he never told anyone.

"I was gonna tell you, thanks Harry." Cisco states to them.

"Well, you can explain later, because you need to use your powers to find Dr. Light." Harry tells him.

"How do your abilities work?" Peter asks his friend, intrigued by his abilities.

"I get these feelings, these vibes, visions of the breachers. I'm not sure what triggers it." Cisco explains and he explains it happens in many different ways.

Cisco decides to try touching the mask and it doesn't work. Cisco keeps trying and it's not working for him. "Try again." Harry tells him.

"Cisco, do as I say, okay?" Peter asks his friend and Cisco agrees to do as he says. "Close your eyes, empty your mind. Remember the feeling that you felt when you got these...vibes. Don't think, don't do anything but think. Now touch the mask." Peter walks his friend through what he did to get his senses to work for him when he first began.

Cisco does as he said and starts getting a vibe. He looks and sees Light at a train station and platform 15. He escapes the vibe and looks to the others. "South Plasa train station, platform 15." Cisco tells them and they're surprised it worked.

"What are you waiting for?" Harry asks as the two heroes then leave.

-

The heroes make it to the train station and see millions of people around. "Everyone, get out of here, fast!" Peter yells and they all do, except for Light.

"Why won't you two let me leave?" Light asks them.

"You tried killing an innocent person, also my friend here." Barry says to her.

"It's the only way I can be free from Zoom, unless I kill this universes heroes." Light tells them.

"I'd prefer to be left alive. I have a lot to look forward to in life." Peter tells her as she starts sending flashes of light at them and they duck for cover.

"You got anything in your web arsenal to help us?" Barry asks Peter.

"She's got to have a blind spot. You keep her distracted, I'll attack her from above." Peter tells him and he likes that plan, and doesn't like it.

"Give her more than one targets." Harry tells them. "How's he gonna do that?" Peter asks him.

"By running so fast, Barry is going to create multiple afterimage of himself, a speed mirage." Harry tells them and they see that could give them an edge to take her down.

"I mean, you've traveled through time, this should be a piece of cake." Peter supports his friend and Barry sees that he's right. Barry starts speeding around and creates images that Light thinks is the real one and Barry keeps making afterimages while Peter gets above them.

"Where are you?!" Light yells as Peter webs her back and pulls her against a banister that knocks her out.

"Told ya' I'd knock your lights out by the end of the day." Peter tells the unconscious woman.

-

They bring her back to Star labs and put her in the pipeline and Barry tells them the plan is like Wells said. They're going on use Light to lure Zoom in and Jay thinks they're making a mistake and doesn't want to be here to see them kill themselves in a fight against Zoom.

"You all have to ask yourself why this man, for years, wouldn't admit that he was responsible for the particle accelerator exploding underground. He may not be him, but he has just as many secrets as your Wells. Remember that." Jay says.

"If you're such a saint, why do you seem to be hiding something?" Peter blurts out and Jay is confused. "I told you, my senses are telling me you're dangerous. Awfully dangerous for a non metahuman. I don't know what you're hiding, but I've tried giving you the benefit of the doubt. And it's not working." Peter tells him and Jay leaves.
