A/N: Sorry for keeping you guys waiting! Last time, the older Clarks notices some changes on Tony lately. Will they figure out why and finish the mission before it's too late? Let's go to Part 2!

The Amazing Spiez!

Operation: Major Enhancement: Part 2

After the mission, the Clark siblings reunited at their house at night as they are having dinner with their parents.

"So kids, how's your school today?" Karen asks in curiosity.

"Oh, you know, classes and stuff," Megan sheepishly said to her Mom, not wanting to reveal their spy secret to their parents.

"Yeah, we're preparing for that basketball match in a few weeks," Lee added with confidence.

"And my project on the science of solar power is going great! I'm heading for another A, guaranteed!" Marc put in.

"What about you, Tony? Have something to share what happened in school today?" Cal asks to his youngest son, who is eating quietly on the table.

"It's so-so. I've just recently took a quiz in Math and passed, plus I got a lot of homework to do back at my room," he said quietly.

Karen and Cal looked confused. This wasn't like Tony to be so quiet or talk about school or homework.

"Uh son, are you feeling alright?" Cal asked.

"He's fine," Megan said. "It's just we had a fight with him a couple of days ago about his immature attitude and…well there's been a lot of tension between us ever since."

"I see," Karen said. "Can we do anything to help out?"

"No I think we got this," Lee said. "Just give it some time."

"Uh, can I be excused?" Tony said.

"Sure Tony," Cal said. Tony then pick up his plate went to the sink and began to clean it.

As Tony cleans his plate on the sink, the older siblings decided to have a secret conversation as Marc whispers to them, "Is it me or is Tony is, you know, less active lately?"

"Yeah, when he got back from the mission, he only went back to his room to study instead of watching cartoons or playing video games," Megan said.

"Plus, he usually pigs out on junk food too," Lee added. "But not this time."

"You think this could have something to do with that accident in the laboratory," Marc suggested. "Because he's been like this ever since he woke up from that."

"Probably," Lee said. "We should talk to Dr. Zimmer and Jerry, about this later."

While the older Clarks continue their secret conversation, Tony was about to leave the dining room after he washed the dishes when he suddenly fell down to the ground and clutches his head in pain. The older siblings notices this and help their little brother up on his feet.

"Tony, are you okay?" Megan asks in worry when Tony forces them to let go of him.

"I'm fine! I don't need you guys to treat me like a sick child! Now if you excuse me, I need to finish my homework before bedtime," he said in a stern tone before going up to his room.

"Wow, now he's acting like Mom and Dad," Lee said.

"Well I never thought I'd hear him say 'homework' and 'bedtime' in the same sentence," Marc added.

"We definitely should talk to Zimmer," Megan put in.

As everyone sleeps peacefully in their respective bedrooms, Tony was having trouble sleeping as he felt something painful in his head before he woke up in shock.

Seeing Marc still sleeping, he realizes he can't sleep for some reason. He must have something to do about the mission or something.

He goes over to a part of his desk and presses a button that opens up a secret compartment. He then lifted a bag out of it and opened it. Inside was one of the mechanical spider, he, Danny, and Miley had gone up against at the Miami base. He'd brought it with him to give to Marc for analysis and possible tracing, but now…for some reason, he felt motivated to do the analysis himself.

"Now, let's see just where you came from," he said as he silently began to work on it.

The next day at school, it's lunch time in the cafeteria as Lee, Marc, and Megan sit down at their table to eat their lunch. However, they noticed that Tony is missing lately.

"Uh, guys. Have you seen Tony lately?" Megan asks in worry.

"Only in class. I haven't seen him during breaks," Lee answered.

Marc then notices something not very far from where they sat from.

"I think I found him. He's at another table," he said.

"Let me guess, girls fawning over him again?" Megan asks in a dull tone.

"No. In fact, he's studying!"

"What?!" both Lee and Megan said in shock. They glanced over at the table and sure enough, Tony was there, surrounded by books and reading them.

"Okay, studying at home is one thing…" Megan started.

"But now studying at school?" Lee finished. "This is really, really weird."

"We should talk to Zimmer right now," Marc suggested. "But I might go back to the house first. I seem to be missing a part of my solar power project back in my bedroom."

"Marc, I can't believe you would skipped us out just for your project," Megan said in a stern tone.

"Don't worry, I'll ask Jerry to WOOHPed me later," he said as he left the cafeteria. "I'll see you when I'm done!"

Seeing that he will catch up later, Lee and Megan decided to leave the cafeteria, too to WOOHP themselves.

As the older Clarks left, Tony notices their sudden disappearance before going back to reading the book.

"So, you're starting a war, eh? Not if I had anything to say about it," he quietly said as he picks up his books and also left the cafeteria with a serious expression on his face.

As Lee and Megan head straight to the lab where Tony got into an accident in the first place at WOOHP, some of the scientists noticed them, which the latter asks to them, "Um, excuse me, do you know where's Dr. Zimmer is?"

"He's at the lab working on our latest experiment. He also gone there to clean up after what happened yesterday," one of them answered.

"Thanks," Megan said as she and Lee continue walking to the lab.

Inside the WOOHP jet, Tony was surprisingly pilots it as he tries to track something in the jet's GPS screen.

"Okay, let's see just where that mechanical eight-legged freak came from," he said. "Maybe the GPS chip I found in it will take me to who stealing the missile codes and why."

Suddenly a red dot on the GPS screen started blinking.

"Ah-ha, gotcha."

Tony then set the GPS, so that way he could track it down again later. He then took his MPCOM and dialed it.

"Danny, Miley, it's Tony. I think I've found something."

Back at the Clark's home, Marc has just arrived in his bedroom and luckily found the missing part for his project.

"Yes! I'm not letting an A+ slipped through my fingers," Marc said in a proud tone when he notices something on his desk.

It was a stainless steel bolt. Marc picked it up and examined it.

"What's this?" Marc said. He looked down and saw several more parts, leading towards the desk drawer. He opened the drawer and saw the duffel bag. He opened the bag and saw the mechanic spider, much to his astonishment.

"Oh my gosh!"

Inside one of the WOOHP labs, Dr. Zimmer was cleaning the table before continuing on his current work when he notices Lee and Megan enter the lab.

"Oh, Lee, Megan, what an unexpected surprise. What's the matter?" he asks.

"It's about Tony," Lee said. "Ever since that accident the other day, he hasn't been himself."

"Yeah he's been doing his homework and chores, paying attention in class, wooing girls with ease, and studying all day," Megan explained. "What exactly was that serum he got doused in?"

Dr. Zimmer then went on to explain what he told Tony about the exact nature of the serum.

"Wow," Lee said astonished. "But what about him getting sudden headaches?"

"Well as the serum expands your intelligence, it also expands your brain and as it expands, so does you're thirst for learning," Zimmer explained. "If the brain is deprived of learning, the headaches are like a little way of saying it's hungry for knowledge."

Lee and Megan stood there stunned and speechless. Their brother's brain was growing along with his intelligence?

Suddenly, Marc rushed in the lab as he shouts out, "Guys! We got a situation! Tony's gone to track down the hacker with his team and why are you guys look like you seen someone lost?"

"Marc, you are not gonna believe this," Lee said. He and Megan then explained what they found out about the serum.

"So his intelligence is increasing by the minute?" Marc asked.

"Yeah, so soon Tony will be just as smart as you, if not smarter," Megan said.

"What?!" Marc said with nervousness in his voice. "Tony…smarter than…me?"

"Uh-oh," Lee said. "He's gonna pop."

"NOOOOOOOOOOOOOOOOOOO!" Marc screamed.

"Uh, quick question, when will his brain stops expanding?" Megan sheepishly asks.

"Well, from a regular dose, a few days at most. But given the amount of he was drenched in, there's no telling when his brain will stop expanding or how long the effects will last," Dr. Zimmer explained.

"Wow," Marc exclaimed. "This could be a Noble Prize winner or something."

"Yeah," Lee agreed. "But you know, now that I think about it…I'm kinda feel bad about the way we acted with Tony the other day."

"Me too," Marc agreed.

"Me three," Megan added. "I mean when you look at it, he was just doing was he believed was the right choice to save those people. And WOOHP does have the priority to protect the innocent."

"Yeah and all we did was rag on him about what he did wrong," Marc said. "If we hadn't done that, Tony wouldn't have quit the team asked for a new one, gotten into that accident and-"

"I know," Megan said. "But maybe we can make it up to him somehow. Marc, you said Tony had taken his team to track the hacker, right?"

"Yeah, he reverse engineered one those spiders they fought and is using the GPS chip from it to track the person."

"Well let's get a lock on his WOOHP jet and find them," Lee said.

Meanwhile, Tony, now with Danny and Miley (whom he had turned back to pick up) in the jet, flew off to the location marked on the GPS.

"I'm surprised you didn't try to go to this place without us, Tony," Miley said.

"If there's one thing I learned the hard way in my time as a spy, it's never infiltrate a place without backup," Tony told her.

"Good point," Danny said. The GPS then beeped rapidly. "And looks like we're here."

The jet approached a seemingly secluded mountain location and landed on a flat piece of land just across from where the signal was. The three exited the jet and surveyed the location.

"Well let's see who wants our missiles, shall we?" Danny said.

"You bet Danny," Tony said.

Using their rocket boots Tony, Danny, and Miley flew to the location and began to look around. As they did, Miley spotted something out of the ordinary: an air vent.

"Hey, guys I don't think an air vent is something you'd find on a mountain, right?," she asked.

"You're right," Danny said and Tony came to look. "You think it'll lead us to the culprit behind all this?"

"Only one way to find out," Tony said as he unscrewed and removed the vent's grate. He then entered it with Miley and Danny following.

Meanwhile, in another WOOHP jet, Lee, Megan and Marc were trying to track Tony's team's location.

"Well, Tony's sure outdone himself this time," Marc said. "I never thought he'd be so capable of such abilities."

"Me neither," Lee agreed. "The serum really brought out the side of him I never thought we'd ever see."

"But you know," Megan said. "I wonder who could be behind this hacking thing."

"Yeah, who'd be crazy and/or skilled enough to hack U.S. military databases for missile codes?"

They all thought about it. Suddenly a thought crossed Marc's mind.

"Oh-no," he said with fear in his voice. "I have a feeling I know who's behind all this."

Meanwhile, Tony, Danny, and Miley were crawling through the ventilation system of the mysterious location. Finally, they came to an exit vent. Tony quietly unhinged it, slid it away, and crawled out, as did his teammates. They found themselves in some sort of control room with a large map on a screen, which Danny seemed to recognize.

"I've seen this in a video game," he said. "We're in a missile launch control room."

"Are you sure?" Miley asked.

"Absolutely positive."

"Well I guess we found the hacker's hideout."

"But who is he?" Tony asked.

"Good question," a voice said. Suddenly, out of nowhere, more mechanical spiders jumped out and surrounded the three spies. The three turned and looked all around at their surroundings as they heard an evil laugh, which Tony seemed to recognize.

"Wait," he said. "I know that cackle anywhere. Show yourself, Davey Hacker!"

Suddenly the onscreen map changed to show Davey himself, grinning evily.

"So you finally figured it out, Tony. It's only too bad you won't live to tell anyone else," Davey said as he cackled insanely.

A/N: Yikes! Cliffhanger! Will Tony's team get out of this one and will the rest of the Clarks get to them on time? Review and stay tuned!
