(I don't own Jimmy Neutron or Doctor Who, but I do know Keith Alcorn!)

The TARDIS materialized in the middle of a forest on some unknown planet. Jimmy stepped out the TARDIS door and Timmy followed.

"So where are we?" Timmy asked.

"I don't know."

"You don't know? Well what year is it?"

"I don't know."

"Well is there anything you do know?"

"Nope. Sometimes I like to let the TARDIS take us wherever it feels like taking us."

"I still don't understand how the TARDIS can just decide to go somewhere."

"I told you, it's alive."

"I know, but how is it alive? I mean it's just a machine."

"Well, my dog, Goddard, is a machine, and I consider him alive."

"I guess, but it still doesn't make any sense."

"Look, it doesn't make any sense to me either. Let's just focus on checking this planet out ok? You go look that way and I'll look over here."

Jimmy and Timmy split up looking for signs on intelligent life. So far they had detected no signs of any technology. Jimmy scanned a tree with the sonic screwdriver, "Looks like there's plenty of plants here but that's it. Find anything Timmy?"

"Nope, pretty much the same thing over here."

A few seconds later, Timmy heard a gasp and a loud crash. He ran to Jimmy's last known location. He found Jimmy lying motionless on the ground. He couldn't wake him up.

Sleeping Jimmy by Digger3000

Before his adventures with Jimmy, Timmy might have panicked. But Timmy remained surprisingly calm, even though he had no idea what to do. He dragged Jimmy back to the TARDIS. He put him on the bed where, hopefully, he would at least be comfortable. Then he went to the control console. Remembering what Jimmy had taught him, he set the date for July 20, 2006 and the coordinates for Retroville. When the TARDIS arrived back in Retroville, Timmy ran for the one person he knew could help, Cindy.

"Cindy! I need your help! We were on this planet and Jimmy just fell down and"

"Timmy, calm down. Just tell me what happened."

Timmy took a deep breath and sat down, "Ok, Jimmy and I went to this planet and he was scanning some plants and all of a sudden he just passed out. I tried to wake him up but I couldn't."

"Alright, I'll call 911, and you go make sure he's ok," Cindy said, and Timmy started to leave, "Don't leave him until the ambulance gets here."

"…I won't," Timmy ran back across the street to Jimmy's room. He wasn't even sure if Jimmy was still alive or why he'd passed out.

Within minutes, the ambulance arrived and took Jimmy to Magic Kitten hospital. Timmy and Cindy rode along on the ambulance. When they got to the hospital, the doctors examined him and took him into a room where they hooked him up to all kinds of machines. Timmy and Cindy weren't allowed in for the first thirty minutes. When they were finally let in, Timmy was starting to freak out.

"What's going on? What's wrong with him? Is he alright?" Timmy asked frantically.

The doctors asked Timmy to sit down and take a deep breath. They explained, "When we bought your friend in, his heart rate was 54 BPM. Now it's down to 50, we normally like it to be between 60 and 90."

"So what does that mean?"

"It means for some reason his heart is very weak, and his brain isn't getting enough oxygen which caused him to lose consciousness."

"Is he going to be ok?"

"We hope so, we're doing everything we can for him, but we don't know what caused this. Is there anything you can tell us about why this might have happened?"

"I don't know. One minute he was fine and the next he was on the ground."

"Ok, well we'll try to save him. But if his heart rate continues to go down he could go into a coma and…he might not make it."

Timmy's heart sank. Cindy put her hand on his shoulder, "Come on, let's go wait in the waiting room," They went and sat down in the waiting room, "Timmy, is there anything else you can remember about what happened?"

"No," Timmy said, "Nothing. It was just like every other day. Jimmy was just scanning these weird plants and he just passed out."

"Did you say weird plants?"

"Well, yeah, do you think the plants have something to do with this?"

"That's what I'm thinking."

"But then why didn't the plants have any effect on me?"

"I don't know, but we have to tell the doctors to look for toxic spores or something."

Timmy and Cindy rushed back into the hospital room. "Timmy remembered something about what happened," Cindy told one of the doctors, "Check his system for toxins, maybe plant toxins."

"Ok, I'll order some blood tests," the doctor said, "But uh, we did find something else."

"What is it?" Timmy demanded.

"There's a…a strange marking on his chest. I don't know if it means anything, but it's right over his heart. And it looks like…it looks like it's burned into his skin."

Timmy approached Jimmy's bed. He took one look at the marking on Jimmy's chest and ran out of the hospital room. Cindy ran after him.

"Timmy, what's wrong? What was it?" She asked.

"Cindy, the marking on Jimmy's chest…it's the TARDIS!"

"Are you sure?"

"Yes I'm sure! I know what the TARDIS looks like!"

"Alright! You don't have to yell at me!"

"…I'm sorry Cindy. I'm just really worried about Jimmy."

"I know," Cindy said, hugging Timmy, "I am too."

"Cindy, I just know the TARDIS is involved in this somehow."

Timmy ran back to Jimmy's back yard where he had parked the TARDIS, and Cindy followed him. Timmy desperately searched the TARDIS for some idea of what to do, but the control panel had hundreds of other gizmos and gadgets that Jimmy hadn't explained to him. After about thirty minutes, Timmy was talking to the TARDIS.

"Alright, TARDIS, Jimmy said you were alive, so tell me how to save Jimmy. Why can't I figure out what's wrong!" Timmy banged his hands against the console.

"Timmy, calm down," Cindy said, putting her hand on Timmy's shoulder, "This isn't your fault."

"I know but…Jimmy said he'd do anything for me. He said he'd do anything to make sure I'm safe, and now he's going to die and there's nothing I can do about it!"

Timmy banged his hands on the console again, this time harder. He hit it so hard that the middle panel popped open, revealing the energy field previously referred to by Jimmy as 'The Heart of the TARDIS.' But the once brilliant light was now dull and dim. Timmy stared at it for a minute, and then he must have had the equivalent of Jimmy's brain blast.

"Cindy…I think I figured it out!"

"What? What is that?"

"Jimmy called it the Heart of the TARDIS. Normally it's really bright but sometimes it loses energy. It's like running out of gas."

"What does that have to do with Jimmy?"

"Well don't you see? The Heart of the TARDIS is weak, and Jimmy's heart is weak. It's like, it's like they're connected somehow. Remember? Jimmy had a marking that looked like the TARDIS over his heart."

"You think Jimmy's dying because TARDIS ran out of gas? …Ok, so how do we fix it?"

"Jimmy said the only way to recharge the TARDIS is by flying it directly through a black hole."

"But…but black holes are dangerous. You're not flying this box through a black hole. The gravity will crush you!"

"No it won't, the TARDIS is completely indestructible."

"Completely?"

"Almost completely."

"No, no way, I'm not letting you do something that dangerous."

"Cindy, I have to. Jimmy could die."

"Yeah, but so could you."

"I'm not just going to sit in a waiting room while Jimmy dies. I would do anything to save him."

"But Timmy"

"Look, Jimmy's shown me so many things. He's shown me planets and spaceships and things I couldn't even imagine. And he showed me something else too…love. I love him Cindy, I have to save him. And I know you'd do anything to save him too."

Cindy looked down at the floor.

"You can stay if you want," Timmy said, "But in about five minutes this thing is gonna be in the middle of a black hole."

Cindy started to leave the TARDIS. She stopped and turned to Timmy, "Be careful, ok?"

Timmy nodded. Cindy rushed back to the hospital to check on Jimmy, and Timmy ran to the control panel and started rolling wheels and pushing buttons. Jimmy had taught him how to get back to Retroville, but Timmy had no idea how to get to a black hole.

Remembering the TARDIS was alive, Timmy said, "Come on! Stupid TARDIS! How do you work? How do I get to a black hole? Go to a black hole!"

Timmy looked into the Heart of the TARDIS, and the energy from inside the control panel poured into his eyes. When he had absorbed all the energy, Timmy closed his eyes and imagined a black hole, and the time rotor began to move up and down. Without operating any of the TARDIS control panel, Timmy had managed to fly the TARDIS to the nearest black hole.

Timmy looked at the main viewing screen, "I did it! I did it, I'm at the black hole! …Now what?"

As the TARDIS drew closer the black hole, it began to shake more violently. Timmy held on tight to the control panel. The TARDIS reached the center of the black hole, and Timmy watched as the Hawking Radiation flooded in through the central tube. The heart of the TARDIS got brighter and brighter, and Timmy knew he was successful in recharging the TARDIS. Now to get back home, he thought, and he set the time and place for July 20, 2006 and Retroville. The TARDIS materialized directly behind the Magic Kitten hospital. Though he has recharged the TARDIS, Timmy ran to Jimmy's hospital room, fearing he may have been too late.

"How is he? Is he ok?" Timmy asked frantically.

A doctor checked Jimmy's heart rate monitor, "I'm sorry…his heart rate is at 40 BPM and falling. It doesn't look like he's going to make it."

Timmy looked down at the ground, devastated. He was sure that would work, but Jimmy's condition only got worse. He went to Jimmy's bed and held his hand. "Jimmy," he said, "I…I don't know if you can hear me but if you can I just wanted to tell you that," Timmy choked and his eyes started to tear up, "that I…I love you."

By now, Timmy was full on crying. But suddenly, the beeping on Jimmy's heart rate monitor started to speed up.

"Hey," said one of the doctors, "hey, his heart rate's going up!"

Timmy turned around, "What?"

"It's up to 55, 60, 65 BPM!"

Jimmy suddenly gasped and sat up in his hospital bed. Timmy turned back around and stared at Jimmy, "Jimmy! You're alive!" He threw his arms around Jimmy.

"What's going on? What happened?" Jimmy asked, still confused.

"You don't remember? You passed out and I put you on the tar…I mean an ambulance. I put you on an ambulance."

"Wow," Jimmy's doctor said, "this recovery is incredible," he checked all of Jimmy's vitals, "If I didn't know any better I'd say there was never anything wrong with you," The doctor checked Jimmy's chest, "Even that scar over your heart is gone."

"Great," Jimmy said, "So can I get out of here now?"

The doctors discharged Jimmy, but not before submitting his case to "Untold Stories of the E.R." Jimmy and Timmy went to the TARDIS, which was still parked behind the hospital.

"So Timmy," Jimmy said, "now that there aren't any doctors hovering over us, what really happened?"

"Well, we were on this planet and you just passed out. I brought you back here and Cindy called 911. The doctors couldn't figure out what was wrong with you, but they did find this marking on your chest that looked like the TARDIS. I went back to the TARDIS and saw that the heart was weak, so I went to a black hole to recharge it," Timmy hugged Jimmy, "Oh Jimmy, I was so scared I would lose you!"

"Hey don't worry about me. I'm completely indestructible."

"Completely?"

"Almost completely."

"I was just so scared because I didn't know what to do."

"Yeah, but you figured it out. You did exactly what I would have done, I'm really proud of you. Plus you saved my life, I owe you one."

Timmy smiled, "Yeah, and I owe you like thirty thousand," They both laughed, "I love you Jimmy."

"I love you too, sweetie."

"There's just one thing I don't understand," Timmy said, "Why did you pass out when the TARDIS lost energy?"

"Because I looked into the Heart of the TARDIS, and the TARDIS looked into me. Now we're connected. Like I said, it's alive. I feel what the TARDIS feels," Jimmy lifted Timmy's shirt to reveal he now had the same TARDIS shaped scar on his chest, "And now you're connected too. Don't worry, the scar will fade away."

"But the TARDIS has run out of energy before and you never passed out."

"Hmm…you're right."

Jimmy boarded the TARDIS, and Timmy followed. Jimmy started looking through the TARDIS computer logs.

"Timmy," he said, "look at this. According to the logs, the TARDIS lost over 90 of its energy in the span of five minutes."

"What could cause the TARDIS to lose power that fast?"

"I don't know, but something on that planet just sucked all the energy right out of the TARDIS. That's why I passed out, my heart couldn't handle the rapid energy loss."

Jimmy went to the control panel and started turning the wheels and punching in coordinates.

"Jimmy, what are you doing?" Timmy asked.

"We're going back to the planet."

"You mean…the planet that almost killed you?"

"Yup," Jimmy said as he started pumping the engine, "Hold on, Timmy!"
