In the Lab with Donald, Leo, John, Emma, Adam, Bree, and Chase

Dad walks in and says "Okay, your mission supplies are packed, the schematics have been uploaded into John's chip, and your transport is on the way. Did I forget anything?"

Bree says "No. We'll just guess what the mission is and see how it all plays out."

Dad says "All right. A particle collider is a three-mile-long  underground facility where scientists--"

Chase interrupts and says "Race subatomic particles at each other at light speed. For energy experiments."

Dad and Chase chuckled and Chase said, "So cool!"

Dad says "I know."

Then the due says in unison "Deedle-deedle-dee!"

The team gives them a look

Dad says "There is a particle collider in Berkeley that is accelerating out of control, and your mission is to shut it down." 

Adam says "Oh ho! Awesome! I hope one of us knows how to do that."

Dad says "Okay. We have to act quickly. The scientists that operate the facility--"

Dad grabs the chair Leo is sitting in and says "'Scuuuuuse me--" moving Leo aside

Dad begins to type and says "Have already evacuated the control center, and if we don't shut it down in time,"

Dad shows a replication of what the particle collider will do

Dad continues saying "It will create a massive black hole that will implode the entire planet."

Quads look shocked and Leo says "Today?!"

Dad looks at Leo

Leo says "No, that's not gonna work. Today is Shelly Evans' birthday, and her Mom makes the best cupcakes!"

The team looks at Leo a look that says 'What?!'

Leo says "I'm just sayin'. That woman doesn't skimp on the sprinkles."

The team nods

Dad grabs Leo's shoulders and says "Don't worry Leo, you will get your cupcakes." he walks away to the cyber desk and says "John, Adam, Bree, and Chase have all the training they need to shut the collider down."

Leo says "Is that why you said I wouldn't be on the mission?"

Dad says "Leo, you don't know how to handle a situation like this yet, okay? Next time you'll go because John and I will train you to be able to."

Leo says "I don't know, Big D. I think these guys are gonna need some..." then sings "Back-up!"

Dad says "Yeah, and that's why you're gonna be--" Then he copies Leo and sings "Back Up!" then says normally "Here in the Lab with me."

Chase and Adam smile and Adam laughs

Adam says "Oh, he said 'Backup' and you said 'Backup.' Saying things twice makes it funny!"

Then Adam realizes and says "Oh! Saying things twice makes it fun--"

Dad and Emma yell in unison "Stop it!"

Then two balls of electricity come in and it looks like two car seats with something like a big baby chair with something to set something

A man and girl yell in unison "No, no, no!!!! Aaaah!"

the team yells "Aaaah!"

Adam jumps up in Chase's arms Bree hides under the cyber desk Dad protects Leo by putting an arm out to keep him behind him. John does the same to Emma as his dad did to Leo

The man and girl just sat there shocked at what they heard

Dad says "Nobody panic! Probably just the cable guy."

The Man says "Come on, Big D, I just came from seven years in the future. Your time machine actually worked!"

The Girl says "Grandpa, it's us! Leo and Nora!"

Dad looks at Leo

Adam says "Whoa! The cable guy's got the same name as you!"

Emma says "John? Did the seven-year-old girl say her name was Nora?" 

John says "Mmm-Mmm, Yup she did. It's our Nora."

Emma smiles as does John

Leo says walking forward "Wait. If you're really me, then you'd know the handshake I came up with in case I ever became a spy."

Future Leo says "Requesting authentication, Double-o Leo."

then they begin to do the handshake, then at the end, both of them did a spin and pointed at each other and moved their hands the same way.

Leo jumps up and down saying "It really is me!"

John smiles and looks at Nora and says "Nora? Is that you?"

Nora smiles and a tear falls down her face and says "Daddy? Is it really you?"

John says "Yeah, it's me."

Nora smiled and wiped the tear away and ran into her dad's arms

Emma walks forward and says "Nora?"

Nora says "Mom!" and goes to hug her, John joins in and hugs his girls

A couple of minutes later in the Lab with the Team and Future Leo and Nora

Dad says "So you two... The future versions of him and Nora who hasn't been born yet. Do you know what this means? I cracked Time Travel! Ha, ha, ha!"

Then Dad starts to sing "I cracked time travel, I cracked time--"

Then walks up to future Leo and says "Can you do me a favor? When I see you in seven years can you remind me to tell me how awesome I am? Lemme high-five. Like that."

Leo and Future Leo both say in unison "Oh, I'm sure you won't forget. Hey, he just said what I said! Technically, I just said what I said. Okay, you're gonna have to stop doing that. Stop. Stop. Stop!" Then Future Leo puts his hand over Leo's mouth

The Quads laugh with Emma hugging Nora

Future Leo says "It's so good to see you guys!"

Chase says "It's good to see you too..."

Leo hugs them and Chase continues "Older, yet strangely similar Leo."

Future Leo smiles

Dad says "So, uh..." Then he chuckles and continues "What did time travel feel like? Did your body mass increase exponentially as you accelerated towards light speed?"

Future Leo says "Uh, I pushed the button, Felt a lot of wind, there was a big flash-- But yeah, mass and speed stuff."

Dad looks down sad in hope of more of an explanation

Adam says "So if you're from the future... Then what color are my eyes?"

Chase smiles and Bree pulls Adam back and says "Ignore him. Come on, Future Leo, let's jump to 2025 and see what people are wearing. I want to start now and be a trendsetter."

Future Leo says "Sorry, but it took Big D years to just scrape together enough Zanol fuel for me and Nora to come here once and go back."

Bree sighs and says "Fine. But if I end up wearing mom jeans and hair scrunchies, you are gonna get back in that thing and fix it."

She walks back to the group

John looked at Nora from head to toe. He saw a combination of Emma and himself in her.

Nora saw that and says "Daddy? You okay?"

John says "I'm okay. I am very proud of the girl in front of me. You're much like your mother."

Nora had a tear go down her face like she was so relieved to hear that and she hugs John like she hadn't seen him in years or had never known him.

Dad's phone goes off and says "Oh. The collider mission. You guys have to get ready. Head to the equipment room and gear up."

Bree says "Nice to meet you, Future Little brother!"

Adam says "Congrats on growing out of your awkward stage!"

The team leaves except John he had something in his gut to tell him to stay. Leo looked and Leo asks "Hey, why didn't you just bring future John, Adam, Bree, and Chase with you? Let me guess. You and Nora just hopped in the time machine and took off without them. That is so future me."

Future Leo says "Actually... That's why we're here."

Nora says "Dad, Uncle Adam, Aunt Bree, and Uncle Chase..."

Nora and Future Leo look at each other and say in unison "Don't make it to the future."

John and Emma were shocked to hear that

Leo says "What?!"

Adam comes running in yelling "Oh, no! Oh, no!"

Everyone turned around thinking he heard that

Adam says "Forgot to pack my pudding."

Upstairs in the Kitchen

Dad says while everyone is walking to the kitchen coming out of the elevator "What do you mean John, Adam, Bree, and Chase don't make it to the future?"

Future Leo says "You sent me back here with a video that will explain everything."

F. Leo set a device on the counter and a hologram appears on a screen

Leo says "Whoa, what is that?"

F. Leo says "It's a Holophone."

Dad says "I invented the Holophone?"

F. Leo says "No. But you did wait in line six days to get one."

Dad gave a weird face

A video starts to play

Dad, Leo, F. Leo, John, Emma, and Nora start to watch

Dad was fat in the video like he had eaten himself into depression

Future Dad says "Greetings, Past Donald."

Leo and John looked at Dad and he was shocked and says "That's me? Please tell me the Holophone adds a hundred pounds."

John and Leo say in unison "Even if it did, what about the other two hundred?"

Dad gave a weird look

F. Leo says "The next seven years are pretty hard on you, Big D."

Leo snickers and says "Or should I say 'Bigger' D? Am I right?"

F. Leo, Leo, John, and Nora were laughing

Emma smacked John

Then the others stopped

John says "Sorry. I let that get out of weight."

Everyone started laughing again

Emma says "Honey, stop."

John says "Why? I'm trying to distract myself."

Emma grabbed his hand and squeezed it. John knew what that meant. He knew it meant it was okay

The other stopped

Dad looked at the video and F. Dad says "If you are watching this. We cracked Time Travel!  Ha Ha! Inter-dimensional high five."

F. Dad put his hand out and Dad high five it

Dad says "I just high-fived my future self! What?! Look at me! Let me have some joy."

F. Dad says "I sent Leo and Nora back in time to stop you from sending John, Adam, Bree, and Chase on the particle collider mission."

Dad says "What? Why?"

F. Dad says "Now, I'm sure you're asking, 'What? Why?'"

Dad says "I know myself so well. You know."

F. Dad says "As a scientist, I am loath to change the past. But in this case, I have to make an exception. John, Adam, Bree, and Chase... Don't return from the mission. Send John or Future Leo by themselves or send an automated rover in their place. It's the only chance we have to save them."

Dad starts to regret even thinking about sending us on that mission

F. Dad says "Oh, and by the way--" he clears his throat and continues "Every time you say. 'Hey, I think this calls for a cookie.' think about this." F. Dad lifts his shirt and I cover Nora's eyes as everyone screams

Everyone calms down

F. Leo looks scared for his life

Leo just watches Dad

Dad walks away into the Living Room and says "How could I send them on a mission they don't return from?"

Leo says "And how could you let your hair recede with so many trusted over-the-counter remedies available?"

John was shocked to hear he wasn't there for his girls. His dad. His brother Leo.

Dad looked at John and remember he saw everything too

Dad says "Son? You okay?"

John shakes his head no

John steps away from Nora and Emma as if he is the reason they would die if he doesn't step away

Nora says "Daddy?"

John says "I missed all you're firsts?"

Emma covered her mouth crying

Dad saw the pain in his son's eyes

The Leos saw the same thing

John began to cry and say "I was so worried about screwing up your childhood... Screwing up our family, but... I'm not even there."

Emma begins to walk to him, but he steps back

Dad saw what he was doing protecting her and Nora

Emma says "Baby? What are you doing?"

Dad knew and said, "He's stepping back in fear that you'll die with him."

Emma looked at dad and then back at John hoping that it wasn't true but she saw in his eyes that it was true

Dad says "If Adam, Bree, or Chase hear any of this, it'll shake their confidence, just like John, in future missions or their confidence in me. Please tell me you won't say anything to them."

F. Leo says "I promise."

Dad looks at Leo

Leo says "Future me... Speaks for both of us."

As both of them shrug at the same time

Dad shakes his head and says "There's not much time. The collider situation's getting worse by the hour. I gotta go build that rover."

John says "No."

Everyone looks at John

John says "Future you said Send me or Future Leo. I'll go. It's the only way it will take too long to build that rover even with super-speed. I'll take care of the Collider by myself."

John was about to leave when Nora yells "No!"

John turns around

Everyone looked at Nora

Nora says "I just got to meet my Dad. And you're telling me you're gonna go sacrifice yourself to save everyone. We need to save you, Uncle Adam, Aunt Bree, and Uncle Chase so that all of you are here!"

John yelled, "What other way, Nora!" Nora flinched when he did that, He continued "What other way! We need to find it right now! That collider is coming this close to destroying the Earth and we don't have anything else besides just sending one of us in there!"

Emma yells "Don't you dare yell at her! She's trying to protect her father, John!"

John yelled "Yeah! I'm doing this to protect all of you!" Everyone flinched at that. He continues "You think I wanna die? I see Nora looking at me asking me not to go and you think I don't want to be here for her. For you. It's better to have the others instead of none of us. I'm doing this, for you!"

John calms down and says "I love you all. Nora keep an eye on your mom, okay, Sweet pea?"

Nora began to cry and say "Dad, please, please, don't go. I-I just got to meet you and I... I don't want to go through it again, please, Daddy... Don't make me go through it again, I don't want to go through it again."

Nora ran into John's arms

John began crying kissing her head and holding her so tight as he doesn't want to let go

Nora just cried in her dad's chest hoping that he would change her mind

John says "Nora... People need the Flash."

Leo smiled knowing that he used the name he gave him.

Nora looked at John and said, "But... I need my Dad."

John cups her face and says "Nora, I don't have much time, okay? You are so much like me and your mom. And I am so proud of you. And I'm so sorry that I wasn't there to teach you. And I hate that I wasn't there for a lot of things, but, remember... My Sweet Nora... Always Remember... I love you, and I always will."

Nora's lip began to quiver and John kissed her forehead and hugged her

Chase and the other walk in and say "We're good to go, Dad. Just waiting for John to get ready after he's done..."

They saw him hugging Nora and Chase says "Apparently hugging Nora. We'll check in once we Delta point."

John and Dad yell in unison "No!"

Dad says "Uh, I-I mean, the mission's off. Only John's going."

Adam says "Why? We're going with he's our brother. And you said it was urgent."

Dad says "Did I say 'Urgent'?"

Bree and Chase nod

Dad says "I th-I think I said 'Urge...ing.' I was like I was urging you not to go on the mission."

Chase asks "Then why is John the only one going?"

John says "I can get the job done faster than with you all there."

Dad says "See, there. We have spoken. Now go get ready for school."

Chase says "But, Dad. The four of us can handle--"

John and Dad yell in unison "No!!! We said no, and We mean it! our decision is final. Now just... Everybody go get ready for school."

Everyone goes back down to the lab to put the gear away

F. Leo walks over and says "Thank you. Future you would thank you too, Big D."

Leo says "Or should we say 'Bald'-D?"

Both Leos start to laugh with John smirking

John says after they're done "I can't believe I can't tell them I'm gonna die."

F. Leo says "If you do, they find a way to save you. And they'll die in the process."

Nora walked over and hugged him and said, "Are you gonna spend time with me and Mom before you go?"

John smiles at his girls and says "Yeah. We'll go to school and hang out there."

Emma smiled and said, "Yeah, I still have to go to school. And I might lose my Fiance in the process."

John cups Emma's Cheek and says "Emma Anna Wright."

Emma looked at him

John says "I, Johnathon Davis Davenport. Take you, Emma Anna Wright to be my lawfully wedded wife. To have and to hold. From this day forward, in sickness, and health to love and to cherish and 'till death do us part."

Emma says "I, Emma Anna Wright. Take you, Johnathon Davis Davis Davenport to be my lawfully wedded husband. To have and to hold." she begins to break and continues "From this day f-forward, i-in sickness, a-and in h-health to love and to cherish and 'till death do us part."

Dad looks at them and says "That was beautiful. Does anyone here have any reason why these two should not be married?"

Both Leos smiled and shook their heads no

Dad says "I guess I should do this then. By the power vested in me after I study hard to get a ordain. I pronounce you both Husband and Wife. You may kiss the bride."

John smiled and kissed her

The siblings came back up

Dad said while Emma and John were kissing "Well you missed me marrying John and Emma."

The siblings were shocked

The couple stopped kissing and put their foreheads together.

Nora smiled at her parents and says "Honestly you guys were married today as well in the future."

John smiled and said, "I guess I should have done it sooner."

Emma says "I love you so much, John."

John says "I love you, Emma."

Leo walked over and brought the rings out

Leo says "John wanted me to be his best man. So... These are the rings ya'll have put on before doing that."

Emma puts her engagement ring on the other hand and John slips the ring on and Emma slips his ring on and they kiss.

The Siblings were happy that they at least saw that.

At School with the Leos, John, Emma, and Nora

Leo asks "So, you know everything that's gonna happen?"

F. Leo says "Not everything. Little stuff can change without affecting the big stuff. For example..."

Someone tripped and spills his drink on someone

F. Leo says "Last time that were you. Smelled like Kiwi for a week."

Leo looks over at Ella and smiles at her

Ella saw that smiled back and waved

Leo waved back

Leo says "Ella!"

F. Leo says "Oh, that's just painful."

Leo turns back around to himself

F. Leo says "You have no idea what's coming your way, do you?"

Leo says "What do you mean?"

F. Leo says "You'll see... At 8:27." as he looks at his watch

Leo says "What's supposed to happen at 8:27?"

Ella walks over and kisses his cheek and says "Hey, Leo."

Leo turns around and says "Hey, Ella. It's good to see you."

Ella says "Yeah. Emma came by and said that she and John got married. I thought they weren't doing that till after baby Nora was born."

Leo says "Yeah. Remember when I told you about our abilities?"

Ella says "Did something happen?"

Leo says "We have a situation with our bionics. Like, Save the world type deal."

Ella says "Then why are you guys here?"

Leo says "The rest of the team isn't going except John."

Ella says "Leo, is there something you're not telling me?"

Leo says "John is going to die during this mission and there's nothing we can do to save him."

Ella says "What? You guys are family. Why aren't you helping?"

Leo says "John told me not to. And I'm following my leader's orders."

Ella says "Is this why Emma clung to John like it was her last time to spend time with him? And that girl."

Leo says "That's Nora. From the future in 7 years."

Ella says "What? That was Nora? I was wondering why she looked like them."

Leo says "And this is me. From the future." pointing at F. Leo

Ella looked at F. Leo and says "Still handsome as ever."

F. Leo says "Still as gorgeous as the day I took you to the dance."

Ella blushed and said, "Still talks like you. How's our relationship in the future?"

F. Leo pulls out his Holophone and shows a picture of Leo and Ella in the future

F. Leo says "That's you two in Seven years. Pretty cool, huh?"

Leo says "Are you wearing a pink tie?"

F. Leo says "It was a gift from Ella, and we love it."

Ella smiled and said, "What do you feel about the tie Leo?"

F. Leo says "Can I be honest?"

Ella nods

F. Leo says "I don't think it's my color."

Ella smiled and closed her eyes like she was memorizing something.

Then the picture started to change

F. Leo says "What did you do?"

Ella says "Why don't you look at the picture?"

F. Leo and Leo look and the tie was now blue instead of pink

F. Leo says "How did you--?"

Ella says "I thought about what you said. And if I remember correctly, Blue was always you're color. I mean both of you are wearing blue."

Both Leos look down at the clothes and saw blue.

Ella kissed both of their cheeks and says "I won't ask you on a date. In case you have to go to help John. I love you."

Leo and F. Leo say in unison "We love you."

Ella smiled and walked off

Leo smiled and said, "She's right ya know. Blue is definitely our color."

F. Leo says "Yeah, she is right. She usually is."

John walked over and smiled and said, "Ella came over and said that her future with you was great."

Leo smiled and says "Yeah. It is."

John says "Remember something for me, Leo. Both of you."

Leo and F. Leo nod

John says "You both are Nora's Godfather. I talked to Emma about it. I want you both to be a father figure to her... if I don't make it. After all, she deserves one."

They both nod and say in unison "Of course, brother. You have our word."

John smiled and hugged them both

Back at the Lab with Donald

Donald was building the rover and had told John in case he couldn't do it he was still making the rover.

Leo and F. Leo walked in with John, Nora, and Emma and Leo said, "Hey, Big D. I got an 'A' on my history test."

Dad says "Yeah? Did you cheat by getting the answers from Future you?"

Both of them looked at each other and say in unison "We have Super-Intelligence. We don't need to cheat. So, how's that rover coming along?"

Dad says "It's almost ready. In case John can't do it."

then sparks crackle and a small explosion and Dad flinched back

Dad says "You know what," as he takes off the arm and says "Are you sure John, Adam, Bree, and Chase Don't make it?"

F. Leo says "Yes, I'm sure."

John says "Great."

F. Leo saw that and said, "I'll show you. We downloaded the security camera footage from the control room."

F. Leo pulls out his Holophone and its video footage of John, Adam, Bree, and Chase

Adam had ripped the wires out and John had summoned his force-field ball and threw it at the control box

Everything shuts down with a whoosh

Dad says "Well-- They shut it down. They completed their mission. You came back for nothing. I think this calls for a cookie."

F. Leo says "You haven't seen the ending."

The siblings cheer and do a group hug

Then the roof collapsed on them.

John flinched when he saw that.

Dad says "Scratch that cookie."

John was scared but knew he had to do it.

John says "Good thing only one of us is dying."

John got in his capsule and came out and grabbed the gear his siblings set down

John says "I guess I should get going."

Emma walked over and kissed him.

John kissed her back

Nora ran into her dad's arms and he kissed her forehead and said, "Remember what I said?"

Nora nodded and said, "Look after Mom."

John smiled and kissed her head and hugged her.

John began to quiver his lip crying

Dad says "I got to get this thing mission ready in case John can't."

John lets go and wipes his tears off and says "I love you all."

The siblings walked in and said, "Why are you still here? Don't you have a mission to do? The mission Dad won't let us do with you."

John says "You all will understand, eventually. Later everyone."

John stopped at the back entrance and said, "Dad?"

Dad looked over and said, "Yeah?"

John says "We remember that thing we did when I was younger?"

Dad smiles remembering and says "I remember."

John says "Laters, gaters."

Dad begins to cry and says "In a while, Crocodile."

Mom came down and saw John and Dad crying

Mom says "Be safe, Honey."

John says "You too, Mom."

John left wiping tears

Chase says "I haven't heard the say 'Laters, gaters', in a while."

The rest of the siblings nod

Emma smiled holding back tears

Chase says "Why won't you just let us go?"

Dad says "That's not necessary. I just need to buy a few things if John can't... From NASA. They're having a sale. Everything's a million off. I'll be gone for a couple of hours. Leo, you're in charge."

Both Leos say in unison "You got it, Big D."

Dad says "Good, both of you."

The siblings' were shocked that Dad said both

Adam says "He thinks this mission's too big for us."

Leo says "It's not that he thinks it's too big--"

F. Leo says "Leo. We promised."

Bree says "I guess Dad just lost confidence in us."

Chase says "Or he lost confidence in you two."

Bree says "What is that supposed to mean?"

Adam says "Yeah, I'm the one always carrying you two. You're the weak links."

Chase says "Oh, I'm the weak link?"

Adam says "Mmm-Mmm."

Chase says "You can't even spell 'weak link.'"

Bree puts her hands on her hips

Adam says "Can too."

Chase says "You're brain-dead!"

Bree talks at the same time as Chase

Adam says "What are you talking about?"

Leo yells "Hey! Guys! Guys! Guys! Stop! Enough!"

They all stopped cause they knew he was in charge

Leo says "I'm not supposed to tell you this, but... Future me came here to Warn Dad not to let you go on the mission because you don't come back from it."

F. Leo says "God! I never listen to myself!"

Adam says "Don't come back? Wait!"

Everyone looked at Adam and he says "What about John?"

The siblings started to get worried

Leo shakes his head no and says "He decided to sacrifice himself to protect you three. And me. And Emma. And Nora. His daughter." as he points at Nora

Chase says "No. He can't die. It's John. He always comes back."

Nora says "Not this time Uncle Chase."

Chase looked at Nora and she was telling the truth

Chase grabbed his knees to support himself

Everyone saw that

Chase begins to cry not wanting to believe his brother will die.

Chase says "Nora. I am so-so-so sorry. I-I-I can't do any of this without him. He has always been there for me. Protected me, kept me safe. He is the best brother ever."

Adam and Bree say in unison "Yeah."

Nora said, "Dad did it so that all of you live. While only one person dies. Him."

Bree says "That's why you and he got married? Isn't it?

Emma nods

Bree went to her and hugged her and she hugged back

Adam and Chase followed and they all had a group hug

Adam says "We need to save him."

F. Leo says "No. You can't. He made up his mind. He decided that he was going to sacrifice himself to save you all. You're staying here while he does this. Let's hope he makes it. That's all we can do."

Nora says "Yeah."

Bree saw the look on Nora's face and hugged her

She hugged back and said, "Thanks, Aunt Bree. I needed a hug."

Bree smiled and says "It's okay. We'll get through this."

Upstairs After with Leo, F.  Leo, Nora, and Emma

F.  Leo was getting Leo ready for his date with Ella. He had called her and asked if she wanted to and she was asking what about John but Leo just told her that he doesn't want to think about that right now just them.

F. Leo rolls up his sleeves and Leo Says "Hey! Hey."

Leo adjusts and says "Careful. Handsome is delicate."

F. Leo smiles and grabs a magazine and lies on the couch to read

Leo says "Should I really be going to a movie with Ella considering there still might be a slight chance the Earth might implode?"

F. Leo says "Well, it is a pretty good movie."

Emma says "You think every movie is good, till you see the sequel."

Nora laughs and Emma smiles

F. Leo chuckles and Leo smiles

Leo turns to the door and saw a note

He grabbed it and read it 

He turns to the others and says "It's a note from Adam, Bree, and Chase. They went on the mission!"

F. Leo and Nora yell in unison "What?!"

Leo reads it out loud "'Dear Dad, We went to stop the collider. We know we won't make it back, but that's a small price to pay to save you, Leo, John, Emma, Nora, and the rest of the world. P.S. Sorry we get blowned up.' Pretty sure Adam wrote that last part."

Leo says with his phone out "We have to tell Dad about Adam, Bree, and Chase on the mission."

F. Leo says "Oh, no. It's happening."

Leo says "What?"

F. Leo and Nora say in unison "The series of events we were sent back here to prevent."

The voicemail says "You missed me, but leave a message for Davenport, Davenport, Davenport Industries!"

F. Leo ends the call and says "It's the same awful voicemail for the next seven years!"

Leo throws his phone on the couch

They start to pace and Nora and Emma were watching

Leo says "I can't imagine my life without John, Adam, Bree, and Chase."

F. Leo says "I don't have to image it-- I lived it, and it's awful. Davenport is so distraught he spends the next seven years trying to build a time machine so he can stop this one event and get them back."

Leo asks after both he and F. Leo put their one foot on a rock "Why didn't he just come here himself?"

F. Leo says "I don't want to bore you with time travel details, but mass plays into the calculations, and he did not want to write down his weight in front of me."

Leo asks "He didn't fit into the time machine?"

F. Leo says "You saw that man. He doesn't fit into anything."

They both shake their heads

Emma says "Are they always like this? I don't remember Leo pacing like that before."

Nora says "I think it's funny, 'cause he's talking to himself, basically."

Emma smiles

At the Collider

John was working and Adam, Bree, and Chase come running in

John saw them and yells "What are you guys doing here!? Did me and Dad not say enough not to come here?!"

Adam says "We know why you both didn't want us to come here."

Bree says "It's because we don't make it back."

Chase says "And we're fine with that. But you... need to go. You got a daughter to take care of."

John says "What?"

Bree yells "Go!"

John says "No! I'm not going anywhere if you all are here."

Chase gives a look to Adam and he knocks John out and catches him, Bree super-speeds them to the front door of the house leaving John there, and super-speeds back.

Chase looked and saw that John got halfway and says "John got halfway though let's finish this."

Chase looks at Bree and says "Okay. Bree, run to the collider and use your super-speed to create a vacuum to slow that thing down."

Bree says "Oh, sure. Give the girl the vacuuming job."

Chase says "Would you just go?!"

Bree dropped the bag and comes back in a blur and says "Done."

Chase says "Great."

Bree steps forward and says "Wow. So, I guess this is it."

Chase says "Yeah. Let's not talk about it."

Bree says "You know what I just realized? We're never gonna see Nora grow up. We won't be a part of our Niece's life. And I'm never gonna get to wear white and walk down the aisle."

Adam says "Aw. You wanted to work at the movie theater, too?"

Chase says "No, she wants to get married, but if this is the end. That won't happen. And I guess I'll never get to be the first president of a self-sufficient underwater colony. So long, Chaselantis."

Bree says "We were a good team while it lasted, guys."

Chase says "Yeah. Thanks for always being there."

Adam says "Of course."

Bree says "You too."

They go back to work 

Chase says "Hey, can you hand me that voltometer?"

Bree says "Yeah. Here." she tosses it over and Chase catches it

At the Lab with Both Leo's

Leo was carrying some food and F. Leo says "I'm not letting you do this. It's too dangerous."

Leo says "I'll be fine."

F. Leo says "I'm not worried about you, I'm worried about me! Besides you're gonna miss your date with Ella." 

Leo says "I'm okay with it. Besides, she said that if I had to cancel she would understand. She knows of our bionics. She knows If I have to go and save the world she won't care about it. As long as I come back. I'm not planning on dying."

F. Leo says "Again, I'm not worried about you, I'm worried about me!"

Leo says "Look, I'm the only chance Adam, Bree, and Chase have."

Nora came running in and yells "Dad's in front of the door passed out."

Leo and F. Leo ran to the door and got upstairs and opened the door and saw him

Leo bends down and says "John? John, talk to me?! John!?"

Leo smacks him and John shoots up and says "Ow! That hurt."

Leo says "You weren't walking up."

John says "Smelling salt works just fine. The siblings. They're at the mission. They knocked me out and Next Leo slapped me."

F. Leo says "Not good."

John super sped away

Leo says "Screw it. I'm going without a bag!"

He followed

F. Leo says "Stay here, Nora. Don't follow. I'll make sure they all come back."

Nora nods and he speeds away

At the Mission

The siblings had just gotten done and were about to shut it down and an alarm goes off

Chase says "We're running out of time. Adam, rip the panel off."

Adam nods and rips it off and Chase summons his force field and shrinks it into his ball and throws it at the panel the electricity turns it off and the red lights turn back to green going down.

John yells "Guys!"

Adam saw him and says "You're awake."

John says "Did you guys finish?"

Chase says "Yeah, we just did."

John yells "Move! The room is about to collapse."

A rumble was heard as they didn't hear that John moved him out of the way and was crush by the rumble

They yelled in unison "No!"

A Voice comes and says "Guys!"

They saw it was Leo and F. Leo.

They saw the siblings look at the ruble

Leo fell to his knees he wanted his brother.

Then they heard a cough

F. Leo immediately starts to move the concrete and sees John cough

John yells "Next time I say to move you move!"

They were happy and all of them hugged

John says "Let's all go home. Emma's probably thinking I'm dead."

They nod and speed back home

At the Davenport Residence

Nora was pacing

Dad was pacing too.

Mom was sitting down bouncing her knee up and down.

Emma was too

Then Everyone except entered the house

Nora and Emma ask in unison "Where's John?"

A voice says "Right here."

They turned and saw him

John standing in front of them

They immediately hugged him and started to cry

He hugged them back and kissed them both

Dad says "I was so worried. And You..." pointing at Leo

Dad says "You are grounded until." He points at Future Leo and says "Until you become you."

Leo says "Dad, I know it was risky. But we got it done. They're alive. Even John. We found a better solution."

Dad hugs all of his kids even John

They could tell he was worried about them all.

F. Leo and Nora say in unison "Well, it's time to go back to our time. We changed the event."

Leo says "Bye."

John says "I love you, Nora."

Nora says "I love you too, Daddy."

They share a hug before they all go down to the lab and see them take off

Leo says "I miss me already."

John says "I miss Nora."

Emma says "Me too." 

They all smile and go back upstairs.
