A/N: Hope you're enjoying the story. OH, and I dedicate this chapter to Nicktoons Squad whose review broke my record of reviews for any of my stories! Thank you, my friend and thanks to you all!! Now here is Chapter 11, minus the 'owning of the characters' thing.

His Own Worst Enemy—Chapter 11—On Course

Tucker quickly sets up the device they need to alert them of anything coming out of the time portal, and the threesome then return to the specter speeder and head back toward the Fenton Portal. In no time, they arrive at the Fenton home.

They all meet in Jazz's room and start their tasks. While Sam digests the book, Jazz researches any information about ectoradium on her computer and Tucker continues to explore and input new programs onto his PDA.

After a couple of hours of concentration on all of their parts, Sam, whose eyes are still glued on the book, suddenly blurts out, "This is the strangest book I've ever read!"

"Because it's alive?" Tucker answers, looking up from his PDA.

She then looks up at Tucker and says, "No, because for such a small book, it has so much information in it. I mean, just when I seem to get to the end of the book, more pages mysteriously appear and there's even more stuff to read!"

"Doesn't it have an index or table of contents?" He asks.

"I didn't see any. And I do wish it did have one, though, so that I can get some sort of hint of what Clockwork wanted me to read. At this rate, I might never finish the book!"

Suddenly exasperated, she shoves the book against her thighs, closes her eyes and yells to the ceiling, "I need some sort of freakin' guide!"

At the precise moment she uttered the word, 'guide', a page labeled "Guide" instantly appears and she is so rattled by that, she screams.

"What's wrong?" Jazz utters, startled away from looking at her computer.

Sam excitedly says, "When I said the word, 'guide', a "Guide" page just popped out of nowhere!"

Tucker quickly adds, "Well, don't just gawk at it, look at the contents before the book changes its mind!"

Sam slides her finger down the page and gasps. "That's it! Chapter 25! "Ghost Illnesses and Herbal Remedies!" Instantly, that chapter appears under her finger. "Cool! It's voice activated!" She says, awed.

"Good to know that it's in tune with the twenty-first century, too!" Tucker quips.

Meanwhile, Jazz has returned to the computer and after a few more minutes, it's her turn to yell. "I found it! Here's the chemical make-up of ectoradium! I'd hope that I would find it!...And guys…?"

"Yes?" Sam and Tucker say, momentarily glancing up from their tasks.

"It's time to tell my Mom and Dad. If we're to find out all we can, we need to have their expertise in chemistry and ghost make-up."

Neither of her friends disagrees.

---------------------------------------------------------------------------------------------------------------------

"What do you mean you can't find Danny?" Maddie gasps.

Jack, as bewildered as ever, asks, "You lost him at the carnival?"

Jazz bites her lips and admits, "No! We never went to the carnival. We went to see a ghost friend of ours and…"

"You have a friend that's a ghost?" Her mother interrupts, both aghast and intrigued.

"Yes, it's a long story, Mom, but we have something more important to talk about that we hope will help us find and help Danny. It's about ectoradium. We already know that ghosts can't touch it. But we need to know if ectoradium does anything else to ghosts."

Surprised at the subject of her query and then looking at all the kids, Jack utters, "Ectoradium? You mean the stuff that made up the disasteroid? I was able to take a sample from the spaceship before we tried to destroy it. We have been studying it for awhile, and have some data on it."

Jazz runs over and gives her dad a huge hug and says, "You're the best, Dad!"

"Thanks, Princess. Now what do you need to know about it?"

"What else can ectoradium do to ghosts?"

"Well, it can destroy them!" Jack begins.

Sam, Tucker, and Jazz gasp.

"What's wrong, honey?" Maddie asks, worried about their reaction. "What does ectoradium have to do with Danny? Was he exposed to it?"

Jazz, though hesitant, answers, "Uh, we don't know, but if he was, it wasn't the solid stuff. It was some kind of mist. And you also need to know that there's a very bad ghost from the future who wants to destroy and rule the world, well, really both worlds—ours and the ghosts'-- and…"

"Is it Plasmius?" Maddie interrupts.

Hedging and not wanting to divulge who the ghost is, Jazz finally replies, "No...This one's more powerful, and in some ways…more evil."

"And he has Danny?" Maddie gasps.

Jazz continues, "We think so, but we're not sure. But Tucker has been able to devise a way to detect him…"-- And Jazz also thinks--"'or Danny for that matter'--"...should he return. Until then, we felt we needed to know all we can about ectoradium, just in case Danny was exposed to it."

"Who is this evil ghost anyway?" Jack asks.

Still unwilling to explain everything to them, she replies, "There'll always be some sort of evil ghost trying to take over the world, so can we just concentrate on defeating this one, please?"

"Jazz's right, Jack." Maddie adds, getting more worried at the thought. "Let's see what data we've compiled on ectoradium."

They punch on their computer and then after analyzing the facts, Maddie explains, "It looks like in its normal state, which is the solid form, it just repels ghosts, sort of like being zapped with electricity. That is why they can't touch it. But when it's broken down into its components, mixed with certain compounds, and changed to an aerosol, it is more powerful. In fact, it becomes a poison to the ghosts." She reads a little more and continues, "When given in mild doses, the aerosol mist only makes the ghosts ill. But when the ghosts are in that state, they can be compelled to do things against their will, no matter how hard they resist…It doesn't appear to affect their strength at first, but they can suffer from periods of weakness if they exert themselves or are hurt..."

"…Other symptoms include having a change in their ghost skin tone, and fluctuating degrees of eye color variations. Usually during the first stage of infection, they will have semi-solid red eyes, and then in the later stages, intensely glowing red eyes. But much like having different temperatures during a fever, and especially if they make any attempt to fight the infection, their eyes will show it, by the amount of color fluctuation."

All three teens swallow hard at the news, as Mrs. Fenton continues to read. "But when given anything more than a mild dose of the gas, the poisoning not only makes them obey whoever is commanding them, but the illness will progress, worsening to the point that the ghosts phase to oblivion."

No one at first can speak after hearing this. Jazz then says, "That must be what that evil ghost is up to! To bring all ghosts under his control."

"Or he might want to get rid of them all," Tucker adds.

"Yeah, and if he did both, he can use the other ghosts to control our world, and then he can rid of them whenever he wanted," Sam surmises.

Jack and Maddie look at each other and then the teenagers, fascinated by their logic and unsettled by what it implies. "So that's what you think this ghost wants to do?" Maddie finally asks.

Jazz answers. "It's very possible…but we don't know for sure. Anything else about ectoplasmic poisoning? Is there a cure?"

"We haven't researched that part, yet," Jack volunteers. "We just finished compiling all the attributes of the substance."

"Danny!" Sam utters under her breath, fretting for him.

The book she's still holding throughout this entire conversation shudders just as she utters his name. "What is it, uh, Book?" She asks it.

It shudders again.

On a whim, she opens it and "Chapter 25: Ghost Illnesses and Herbal Remedies" appears.

"OK. Whatever you say. Until we can figure out what to do next, it's time to read 'Chapter 25'!"
