Jimmy Neutron was walking down the streets of Retroville. He was thirteen years old but he was still the resident genius. But he was also apart of the biggest power couple, between him and Cindy Vortex. Jimmy was pretty happy that things worked out between him and Cindy. Even though they had a lot of fights, that was pretty normal, especially when they were younger.

"I'm so glad you are mine," Jimmy flirted, kissing her hand.

Cindy giggled, "Why thank you, Neutron."

Jimmy smiled wide. He had been dating Cindy ever since his return from Dimmsdale. He couldn't figure out what happened, he still couldn't. Cindy never told him what had happened between her and Timmy Turner, his best friend in another dimension.

"Why won't you tell me?" Jimmy questioned one time.

"I keep telling you, I won't tell ever!" She declared, determined.

Truth was, Cindy knew that Timmy was like a brother to her. Timmy felt it, he must've...

Two Years Ago

Timmy was with Cindy, all alone. The Retroville gang (minus Jimmy and Goddard) had gone back home. Timmy wanted to talk to her alone and she couldn't help but wonder why. Timmy had her hand, which made her a bit more jumpy. Maybe he wanted to talk about their relationship? If that was the truth...

"You okay Cindy?" Timmy asked, gaining her attention.

Cindy nodded, a bit too quickly as she answered, "Yeah, I'm okay, Timmy." When she saw his look, she added, quickly, "Honest!"

"Cin..." Timmy started to say.

Cindy blushed a bit as she babbled, "Uh, don't you think it is too early for different nicknames, Timmy? I mean, we aren't a couple!"

Timmy smiled and replied, "Cindy, please. Calm down." He made her look at him, their blue eyes meeting instantly. Timmy's were blue like the ocean but much purer. Cindy couldn't help but feeling flushed, looking into them. She felt out of her skin, though. She knew why. She had to tell Timmy. But that's when he said something low, "I know."

Cindy raised an eyebrow and questioned, "You know what?"

"You had planned to make Neutron jealous for him to notice you," Timmy answered, surprising the blonde.

She knew Timmy wasn't that bright but it was his sense of humor she liked. So how did he know her plan before Jimmy did? Timmy wasn't a genius. He was just an average kid that no one understood.

"How did you know my plan?" She asked, raising an eyebrow.

Timmy chuckled as he answered, "Let's just say, I'm brighter than you think."

"Apparently," Cindy stated, a bit blown away. She looked at him and asked, "Then why did you want to talk to me?"

Timmy rubbed the back of his head and answered, "Honestly? I just wanted to thank you for everything and apologize for the way we acted towards you and your friends."

Cindy smiled at that as she stated, "Thank you, Timmy. But you are saying all of this like I won't see you again."

"Well, you might not," Timmy forewarned. "At least not until Neutron can invent a cross-dimension transporter."

"He came close a few times but it turned messy," Cindy responded, tapping her chin in thought.

Timmy told her, "Well, that doesn't surprise me. The guy maybe a genius but he sure doesn't know the meaning of multiple tests." Cindy was blown away by this yet again. Timmy was right. A good scientist knew that multiple tests are essential for new inventions. Her face must've gave something away as she heard Timmy asking, "What's with the face?"

Cindy shook her head as she answered, mostly, "Every time I think I have you figured out, you surprise me Timmy Turner."

"That a good thing?" Timmy asked, raising an eyebrow. Cindy giggled, kissing his cheek. Timmy smiled wide, smiling. "Gosh..." He chuckled.

"Always wanted a sister?" Cindy asked, smiling.

Timmy didn't answer for a minute before he answered, "Something like that."

"You are a mysterious soul, Timmy," Cindy stated, giggling.

"Thanks," Timmy replied.

Cindy nodded as the two of them walked back to Jimmy. Jimmy was waiting patiently with Goddard. Timmy went over to the robot dog, petting it behind the ears.

"Whatcha talk about?" Jimmy asked.

"Nothing you need to know about, Nerdtron," Cindy answered, rolling her eyes.

Timmy laughed to that, hiding something in Goddard. Goddard whine, licking his face. Timmy laughed more. Jimmy smiled sadly as Timmy got to his feet.

"Guess this is goodbye," Jimmy stated, offering his hand to Timmy for a handshake.

Timmy changed the gesture to a fist bump as he replied, "This isn't goodbye. This is until we meet again."

"You think we will?" Jimmy asked, sounding a bit concerned.

Timmy nodded as he answered, "Yeah, after all, we may live in different dimensions – but that does not mean we should give up on our friendship."

"True," Jimmy agreed.

That's when something he didn't expect happen. Timmy hugged him. Jimmy was surprised by this at first but he slowly returned it.

"In three years?" Timmy asked, hopefully.

"I hope so," Jimmy answered, near tears.

Timmy pulled away from the hug, with a huge smile. That smile...why was it so familiar to the genius? He was about to ask when he heard Goddard bark. Cindy was already through the portal and the robot dog was going.

"That's your cue," Timmy stated, backing away.

"Timmy," Jimmy started to say.

"See you soon, Jimmy," Timmy interrupted as Jimmy went through the portal.

And that was the last time Jimmy saw Timmy. Granted, he was really close to finish the project. He had departed from Cindy and now was with Carl in the lab. But couldn't help but wonder... He had only seen that kind of smile once in his life. And that's when he met the inventor of a time traveling De Lorean, Doctor "Doc" Emmett Lathrop Brown... Could it be possible...?

Carl finally asked, "Hey, Jimmy. Are you okay?"

Jimmy sighed as he answered, "Quite frankly, Carl, no. I'm still thinking of what Turner told me before he left."

Carl's eyes widen and stated, "Oh, you mean the time thing."

Jimmy nodded as he questioned, "Does Timmy's "fairy computer programs" allow him to go back in time?"

Carl shrugged and answered, "I honestly don't know, Jimmy. I mean, he is our best friend and everything but the way he wrote that letter reminds me of Doctor Brown."

Jimmy perked up at this as he asked, "The inventor of a time traveling De Lorean?"

Carl nodded this time and answered, "Yeah, the one you were telling me and Sheen about recently."

Jimmy got curious as he examined Timmy's letter that he had given to Cindy, when they were acting like jerks towards their friends. The more he re-read the letter, the more he thought Carl was right.

He exclaimed, "Einstein's ghost! You're right! He does write a lot like Doctor Brown!"

Carl asked, "But does that mean anything?"

Jimmy answered, "I don't know, it might mean nothing at all."

"Oh, you are very wrong about that, my old friend."

Jimmy and Carl spun around as they saw a De Lorean there, with its driver standing in front of it. ...and it was Doctor Brown himself.

Carl shouted, "AH! Jimmy! He's real!"

Jimmy breathed, "Holy Heisburg! You are real!"

Doc replied, "Yes, I am real, Jimmy. Even you should know that."

Jimmy responded, "I just wasn't expecting this. To what do I owe the honor?"

Doc looked around and asked, "Where's Sheen?"

Carl answered, "Outta town..."

Jimmy questioned, "Hold on, how do you know Sheen or any of us for that matter?"

Doc breathed, "Great Scott! We didn't meet yet! This is what I get for not fixing those time circuits! But, I guess, you deserve to know now what's going on."

Jimmy replied, "Would help."

Carl added, "Y - yeah..."

Doc explained, "You see, in my future - your present - I have a great nephew who is a close friend of yours. I was supposed to go into the future to help your future self from losing your son but I've wounded up in the wrong time, it seems."

Jimmy repeated, "Save my future self from losing my son? What are you talking about?"

Carl added, "And could you put in terms I can understand?"

Doc responded, "Your future son is about to destroy the friendship that you and my great nephew had built over time by stopping a marriage...your daughter's marriage. Now, if your daughter marries my great great nephew, it would secure the friendship."

Jimmy put the pieces together and said, "But my son doesn't want that to happen."

Carl wheezed, "That's kinda of sad..."

Doc replied, "Quite so my great nephew told me to try and stop this by going to the future and warning the future you, Jimmy. But since I'm here instead of there, I'm warning you now. Don't let this marriage be stopped."

Carl whispered, "Sounds easy.."

Jimmy responded, "While this is a great warning and all there's just one problem... I don't know who your great nephew is!"

Doc handed him a piece of paper and said, "Now you do. But wait until I jump back into the time stream, okay?"

The young genius of Retroville nodded as Doc went into the De Lorean and disappeared with three sonic booms and a pair of fire trails behind.

Carl looked at Jimmy and asked, "Aren't you going to read it?"

Jimmy looked at the paper and suddenly smiled at the name.

He whispered, "Yeah...that figures."

Years later, it wasn't until the events that unfolded that everyone found out that Doc's great nephew was Timothy "Timmy" Tiberius Turner. Carl looked at the paper and gasped.

He breathed, "Small headed Timmy? He's related to Doctor Brown...?"

Jimmy stated, "Actually, that doesn't surprise me, Carl. Turner knows how to get himself into trouble."

Back with Doc, he had landed back in 1897. Clara was in the shop, seeing that Emmett was back. She waved him over, standing with a man. He was in his thirties, had messy brown hair, stunning blue eyes, bucked teeth, wearing a brown cowboy hat, a black undershirt, a gray pullover with brown and red stitching, brown jeans, and cowboy boots. Doc pulled the De Lorean into the shop, quickly going over to his wife.

Clara commented, "Emmett, this young man wanted to talk to you."

Emmett stated, "I can tell that." He turned to the young man and asked, "Timothy, why are you here?"

Timothy perked up as he answered, "Doc, I'm surprised you recognized me."

Emmett explained, "Timmy, the younger version of you, told me about your horrible timeline ran by Vicky."

Clara raised an eyebrow and asked, "Wait, he's that same man?"

Timothy nodded as he answered, "Yeah, I'm the same person. My galaxy is also tied into the one where Luigi becomes king with Peach by his side. Rosalina's galaxy."

Emmett looked confused as he questioned, "Rosalina? Isn't she Dimentio's older sister?"

Clara shook her head in confusion as Timothy nodded again. Emmett paled, hanging onto Clara.

She asked, concerned, "Emmett, what's wrong?"

Emmett told her, "It's starting. The chaos is starting."

Timothy added, "Yeah, I feel it too. Luke is insane now. That starts a chain reaction in my galaxy."

Clara asked, "So what happens to you, sweetie?"

Timothy shrugged as he answered, "I go and find my younger self now."

Emmett stated, "We have to stop being prisoners of destiny."

Timothy replied, "It'll never happen, Doc. And we both know that."

With that, a green time portal appeared as Timothy walked through it.

Clara turned to Emmett and stated, "I have a feeling, like you said, the chaos is starting..."

Emmett nodded in agreement, heading inside with her.
