Barry ran to New York after Peter sent a heads up warning to Danny Rand and he was rushed over with his mask in hand.

They filled Danny in on their plan and what they're up against and what he needs to do.

They start distributing the cure to the CCPD so that they can help the metahumans so they don't get killed.

Cicada showed up at CCEU and stole a quantum tunnel converter that can transform dark matter to practical energy. She plans to use her dagger to power the atomizer.

Cisco knows what she would need last for it to work and gets to work finding it.

Peter took a quick run to Jitters to meet up with Thomas Snow who Peter wanted to ask him an important question.

"Peter Parker." Thomas greets Peter as he meets up with him.

"Please, sir, it's just Peter." Peter tells him.

"Then please, call me Thomas." Thomas replied and takes a seat. "You said you wanted to talk?"

"Yeah." Peter says. "I wanted to do it without Caitlin, or everyone else around."

"You wanted to talk to me alone." Thomas recaps. "What is it about?"

"Basically...I know we don't have a lot of history, and with everything going on, Cicada, children coming from the future to help stop him. It's a bit of bad timing with a murderer on the loose, but there doesn't seem to be a better time approaching. After we deal with Cicada for good, and send the kids back to the future...I want to propose to Caitlin, and I'd like your blessing in doing so."

Thomas listens and sees he means it. "Peter, we might not have the best history. Our first meeting, my other half tried killing you. But I saw how you make my Caity feel through his eyes. She loves you. You make her feel happy. And I look forward to getting to know you as a member of the family." He tells him and Peter sees he has his blessing.

Peter returned to Star labs and learns Caitlin and May went to CCPD to help distribute the cure to the metahumans and sees that they're trying to learn about Danny's Iron Fist.

"So...you punched a dragon in the heart?" Cisco asks.

"Yeah." Danny confirms. "I went through the trails and earned the right of the Iron Fist."

"You say that like its normal." Cisco states.

"Normal for me." Danny responds with a shrug ].

Peter even sees Ralph is trying to figure out Thawne's plan and Tommy is trying to help.

Cisco found Sebasion Ollins, an old college roommate, has the device Cicada would need as Barry and Peter go with Danny to get rid of the dagger.

When the three arrived, they look to see no Cicada.

-

"So you keep your identity safe with a mask that covers half your face?" Barry asks, looking at Danny who's wearing a yellow cloth over his head and eyes.

"And what does your mask hide?" Danny asks as Barry's mask is the same.

"Guys, lets just grab the conduit and you can bicker on who has the worse mask later." Peter says when his senses go off and he looks to a suitcase. "Get us out of here!"

Barry speeds them at the last second as the place blows, meaning Cicada was already there and now has everything she needs.

-

"Grace now has everything she needs to use the dark matter from the dagger to supercharge the atomizer." Harry tells them.

"If this is supercharged the right way, she could distribute the death cure to the whole country." Fox says.

Ralph comes in with a theory about what Thawne is up to and the real scientists listen in as Barry and Iris want to believe he's trying to be a good guy.

For whatever reason.

"There's an original timeline with an original Cicada, David Hersch. But Nora interfered with the satellite, giving us Orlin Dwyer. That's also the same night Grace goes into a coma. This is where it gets complicated. At some point in the future, Grace wakes up and becomes her own filled fledged Cicada. Goes back in time, kills her uncle with his own dagger. What happens to all the metas that Dwyer killed? And all the metas that Grace killed in the future? What did she kill them with? And most importantly, what happens to the timeline where Grace never killed Dwyer?"

"Actually, she didn't have the dagger." Tommy tells them. "My few encounters with Cicada, as limited as they were, she never used the dagger."

"Look, right now we need to find Grace, then we will put it together." Barry promises them.

-

They learned that Cicada is planning to attack at the CCPD with the metahumans all there so they all go to stop her.

They're going to send the atomizer to Earth-15, so she can't use it to kill the metas and use Danny to destroy her dagger.

"Hey, cricket freak." Crystal calls her out. "You and I have some unfinished buisness." She blasts Cicada and Peter webs her to the ceiling and smacks her into the ground.

"Is that it?" Tommy asks, kinda expecting more.

"Not yet." Peter says. "Danny, summon your chi or whatever you need to do, destroy the dagger."

"On it." Danny says and Cisco stops him.

"If we shatter the dagger while it's still in there, it could detonate the virus." Cisco warns them.

"Okay, we'll keep Cicada down, you and Iron Fist stop it." Peter tells them and Crystal freezes the doorway so they have some time.

Cicada wakes up and blasts the heroes around easily. She took Peter and slammed him against the wall.

Tommy and Crystal then begin to fight her off mother and son.

A time window opens up and another blast of mist exits it and hits Cicada.

"Oh, look who got my message." Tommy complains as he sees his sister.

"Shut up, bro." Tina Snow-Parker tells him as she helps her family fight off Cicada.

Cicada pulls out two boomerangs and throws them, causing the children to move and dodge it as Cicada fight off Crystal.

She uses Crystal to break through the ice by throwing her into the wall.

Cisco was shutting down the device when it was about to go off.

Crystal gets back up, Tommy and Tina use their powers to help keep Cicada frozen in place.

"Iron Fist!" Peter tells Danny who summons enough chi and Cisco watches as his Fist begins to glow and he swings his fist to shatter the dagger.

Ralph then began to put together that stopping Cicada isn't Thawne's plan. It's the dagger.

That's what's stopping Thawne in the future.

The dagger is what's stopping Thawne from escaping the future prison.

But Ralph figured it out too late as they shattered the dagger, erasing this version of Cicada from existence.

-

When they returned to Star labs, Ralph explains to them what exactly happened and what's going on now.

"So now with the dagger destroyed, that means Thawne is able to escape." Tina realizes and sees she made a mistake.

"What do we do now?" Barry asks.

"Is there anything we can do?" Fox questions.

"Well...there is something." Tommy says and looks to Tina.

"Two somethings." Tina agrees with a smile and raises her wrist with the time watch.

2049

Thawne murders all the guards the second the dagger vanishes, but Nora used her powers to reverse time to bring them all back as Barry and Nora are the first to arrive and they get the guards out and see Thawne in his suit.

"Well, well. It appears as if someone has figured out how to reverse time." Thawne says.

"We figured out everything." Nora tells him.

"Oh, really? What have you figured out?" Thawne asks.

"You sent Nora back, to destroy the satellite, to create a Cicada we could stop. A dagger we could destroy. It was the dagger keeping you here." Barry answers.

"Fifteen years. The second time I've been stuck somewhere against my will. Boring." Thawne says. "Except for your visits. You're leaving out the most delightful part; you both helped me escape. When you went back in time to the time vault. Remember?"

When they went back in time to get Thawne to fix the dark matter dampener, he got the idea to use that to his use.

Thawne races off and the three then fight throigh the city, but Thawne has more tricks up his sleve and was able to outrun them both. He raced at them when a tie portal opens and the Time Sphere exits and smashes Thawne, the entire team exits.

Ralph, Peter, Crystal, Miles, Frankie, Cisco, Tina, Tommy, and Harry with his speedster cannon.

"Isn't this nice?" Thawne asks them. "Team Spider-Flash, back together again...with a few new guys. Ralph Dibny. Welcome. You should be dead." He tells Ralph. "Miles Morales. The Ultimate Spider-Man. Frankie Parker, Metalla. And the two offsprings of the Snow-Parker pack. The Rogue Squadron."

"What can we say? We've been wanting to beat you up since we were kids." Tina states as she now has her own suit on. Her outfit design is not very different from Tommy's or Peter's, except it's all red with light blue sides and dark blue boots with a snowflake on the front and a spider on the back.

"Cisco. It warms my heart to see you again." Thawne tells him. "Sorry about the..." he does a gesture, referring when he killed Cisco in an alternate timeline. "But if I had not die that, you would never have become extraordinary."

"I don't need powers for that." Cisco says.

Thawne rushes at them, Tina activates a time window, opening up behind them as Crystal and Tommy blast him with ice, Harry shot him into one of Cisco's breaches.

Peter is waiting as the breach opens and Thawne falls. He webs Thawne before punching him far away.

Nora and Barry speed into another breach and punch Thawne as he lands with a lightning punch.

Nora grabs Thawne and takes off his cowl.

"It's not my father's legacy that's gobna disappear, Thawne." Nora promises and begins to phas her hand. "It's yours!"

Suddenly, she stops and Thawne looks sympathetic as her arm starts to vanish.

"It was never going to work, little runner." Thawne breaks as Nora starts getting erased from existence. "A new timeline is setting in. That you created when you destroyed the dagger. I had to be sure I could go free."

Barry goes to stop her when Thawne says he can save Nora if he sends her into the Negative Speedforce.

To make sure he doesn't get away, Frankie crushes him in steel and Tina and Tommy freeze him in the metal so he doesn't escape.

The West-Allen's disappear to get it to work. But in the end, Nora vanished and was erased from existence.

The Time Bureau came in and rearrested Thawne so he won't be able to escape.

"Fifteen year's of patience and planning. Wasted." Tina comments as Thawne is transported back to Iron Heights for his sentence to be carried out properly.

"Does that mean this is it?" Tommy asks his parents.

"Yeah, I guess this is it." Peter guesses and looks to Crystal who turns to Caitlin to say goodbye.

"It's been nice to get to know you guys. For as small time as we got." Caitlin says and gives her kids a hug.

"Hey, we'll see each other again." Tommy promise her.

"Only when you see us again, we'll be babies." Tina shrugs as the family all come in for a group hug.

"It's been nice having siblings." Frankie says.

"Well, we got to get home. We're cooking for when you Mom and Frankie get back from New York." Tina says and the two swing off for home.

"I already miss them." Frankie tells them, kinda upset.

"Don't worry, you'll see them in a year or so." Caitlin says and Frankie is actually only now told Caitlin is pregnant.

-

The team returned to Star labs, Cisco decided to take the cure himself and got rid of his powers to have a normal relationship with Kamila, Caitlin went to bring Frankie home for the night and Peter asked her to meet up with him at the waterfront later, Cisco even says he made Crystal and Barry a new suit.

But Peter has one more thing to finally make clear after calling someone to watch Frankie for a hour or two.

"I have faced a lot of deception these past few years. Been through a roller coaster of emotions, ups and downs, hope and fear. And I'm through with the lies. So it's time for the truth to be out there...are you two dating?" Peter finally asks Harry and May.

"Yes." Harry says "Not really." May says at the same time.

The two then face the other.

"Well..."

"I think..."

"Summer fling." May says.

"Yes, that evolves and grows like anything else." Harry replies.

"I still don't know where it's going to go." May tells Peter, who's now getting confused.

"Open to wherever it might lead." Harry continues.

"Anywhere. On or off."

"To share it with people..."

"We'll always be friends, no matter what."

As they keep overlapping one another, Peter sees they're talkng to each other, not really him.

"I'm gonna go because I've got an important question to ask my girlfriend." Peter says and webs his mask to him. "Bye." He says and leaps out the window, leaving the two arguing in his apartment.

-

Down in the sewers, Sarge has finally found the doorway to find the Monitor.

"For so many years, I've traveled across the worlds, across the multiverse to do one thing. To kill you, and now here I stand...ready to end it." Sarge tells the doorway.

"Submit and begin your life anew." A voice says.

"Show me." Sarge tells him.

"The knowledge is within you."

Sarge sees numerals appear on the doorway and he begins to activate the doorway.

It opens and he's consumed by a blinding light.
