Five years later until 2011, the black lemon cars were droving around the new silver lair. Finn McMissile used his four grappling hooks that are disguised as bumperettes, these hooks, attached at the end of strings, can be shot to reach an object at some distance and are strong enough to lift and suspend himself, giving him extra flexibility. He was hanging in the air and watched Professor Zundapp or Z with his spy camera that is located in the left headlight and used to zoom to see details. Finn whispered with his squinted eyes, "I wonder what Professor Z's up to."

Acer asked, "What makes this machine works, Professor?"

Professor Z which is short for Zündapp answered, "Ahem. All we need is a single living organism that has never seen before. In order to find it, we'll use it as a battery for this machine that can destroy World Grand Prix and the rest of the racing competitions so Lightning McQueen and every racer will never race. And then, we will kill them all."

Finn gasped slightly. He turned around as he was about to leave. But suddenly, he saw one of the lemon cars is using a flamethrower to burn him. So he quickly headed to the next floor. Professor noticed him and commanded, "Get him!"

So his henchmen are droving off to chase Finn. Finn drove out of the lair, but is blocked by two cars with flamethrowers. He droved to the right, knowing his way out. He used his grappling hook to swing upward to the roof. He droved faster and got off the building. He dived into the water and transform himself into a submarine mode which is used for underwater escapes. It includes a breathing apparatus, side directional fins, and the rear wheels transform into propellers.

Acer said, "We let him get away!"

Professor Z said with his angry eyes, "Don't worry. I want that living thing to be found in here, this world."

Meanwhile at the Radiator Springs, Sally heard a phone ringing and answered it, "Hello? This is Sally Carrera in Radiator Springs. Can I help you?"

"Hello, Sally. This is Professor Harrison Suman. Guess what? Kristina is coming back here to visit."

She gasped happily, "Really? The human girl that we met her in five years ago?"

"Why yes. She's coming here any minute now."

"Oh my gosh. I can't believe it! Bye!" She droved out of her office and shouted, "Attention, everybody! Attention! Kristina is coming here any minute now!"

Mater asked excitedly, "Really?"

Lizzie asked, "Right now?"

"Yes! Everybody! Make a welcome sign! Hurry!" Sally exclaimed excitedly.

Then, Professor Suman and I in the cart with dome shaped window or glass hatch that is hooked by Professor Harrison's back, were arrived. I wore a teal blue and black sleeveless dress with black blazer, black shoes, my curly hair is now cut and down to my shoulders and it tied in a partial ponytail in a black hair bow. I exit it and run towards the whole gang in Radiator Springs town. I am now 17 years old and looking slightly different from my 12 year old preteen self. I smiled, waving, "Hi, everybody! I missed you all!"

"We missed you, too, Kristina!" They exclaimed happily as they drove over to me.

Mater approached me and smiled as he examined me, "Why look at you, Kristina. You grow up so purty."

I giggled, "Why thank you, Mater. I think you're a cute sweetie pie."

"Aww, thank you, Kristina." He smiled with a blush on my face.

"You're welcome."

Lightning approached me and smiled, sticking his wheel towards me for him to shake my hand, "Heh heh. Welcome back, Kristy."

"Thanks, Hot Shot Lightning." I smiled more, shaking his tire wheel gently with my bare hand.

"Hey, I like that nickname you gave me, girl."

"Yeah, I feel like an outgoing, sweet teenager." I smiled.

Guido smiled as he raised and waved one of his lifters to get my attention, "Pit stop!"

I smiled with a gasp as I noticed him, my long time boyfriend, "Hiya, Guido!" I ran and hugged him happily. He hugged me back. I smiled, "I missed you so much."

"Me too."

We released each other.

I smiled, "Remember my promise I made when I was 12?"

"Yes. You were right, Kristina. A promise does comes from your heart and it has to do with hope and wills. If you made a promise, then you will with all your vow or heart."

I giggled, "That's exactly what Hudson Hornet said, Guido."

Sheriff said worriedly, "But Hudson is dead already."

"Yes, I know. I saw him in the Pixar movie, 'Cars 2.' I missed him really." I said concernedly.

Luigi approached me and smiled with a gasp, "Oh Kristina, you returned at last!" He stared at my older self with his shiny eyes, "My, look at you. You grown up into a beautiful teenage girl with a cute dress and your new fancy haircut."

I giggled, touching my hair, "Yeah, the hairdresser cut my hair shorter when I was 13 before 14 since it was kinda hard to brush and take care of it. Then, I decided to let my hair grew longer since I thought it'll be beautiful on me again."

Guido smiled, "You're already beautiful just the way you are."

Flo smiled at me as she approached me, "Yep. You are thousand times beautiful in the whole wide world."

"But beauty on the inside is all that matters, Flo." I smiled.

Mater approached me again and smiled, "Hey Kristina, check out my moves!" Then, he made some karate fighting moves, screaming, "Hiya! Hoo-wa! Ya!"

I giggled more and smiled, "Oh Mater, you're so funny and cute."

"Oh thank you, Kristina. You're very sweet with that sense of humor of yours."

"You're welcome and thank you, Mater." I smiled.

Then, we all laughed.
