I do not own Phineas and Ferb.

The Firestorm Girls know about the O.W.C.A, but were sworn to secrecy by Major Monogram and haven't told their teammates about the true purpose of the organization. That's why Second Dimension Candace, Phineas and Ferb don't know that their Perry is a secret agent.

Welcome to Your Doom

The metal claw pressed over Phineas' mouth made it difficult to get any air into his lungs. His vision grew hazy, but the last thing he wanted to do was pass out. He wanted to be aware of his surroundings-that way, he could figure out a way to escape.

The redhead peeked overtop the metallic finger that obscured most of his sight. Dark purple and green buildings were a blur as the robots that held him and his brother captive raced through the quiet and deserted streets. Phineas struggled to turn his head so he could check on Ferb but the iron grip made it impossible to do so.

We can't be in the Second Dimension, Phineas thought desperately. The Dr. Doofenshmirtz from this dimension reformed when Dr. D gave him the toy train!

The robots then halted at the base of the building and Phineas could dimly make out the reflection of the robots in the window panes-Normbots, to be more precise. Phineas could feel his heart pound furiously as the Normbots flew upwards, to the very top level of the building.

No, I can't freak out. I can't give that dictator the satisfaction of seeing me scared, Phineas told himself sternly. I have to keep calm and hope that Perry and the others figure out what happened to us. Until the entourage shows up, Ferb and I will have to find out what Dr. Doofenshmirtz wants from us.

The Normbots flew through the skylight and landed on the purple-tiled floor. Phineas and Ferb were thrown roughly to the edge of a sleek purple desk, where the one-eyed villain was sneering down at them. "Well, well. Look who decided to drop in for a visit."

Phineas cast a quick glance at Ferb and was relieved to see that his brother was fine. The redhead turned back to the dictator and glared, trying to resist the urge to gulp as much air into his lungs as possible. The little suffering he was experiencing would bring joy to Doofenshmirtz, and Phineas refused to show it.

"What's the matter? The first time we encountered I could barely shut you up and now you're acting like your little sidekick." Heinz pressed his gloved-fingers together and smirked. "Too frightened to speak?"

"Not at all," Phineas managed to get out. "Just confused, I guess you could say."

Ferb nodded his head in agreement and took a small step closer to Phineas.

"What's there to be confused about? I kidnapped you. You're my hostages. That's all there is to it."

Ferb pointed to the toy train mounted proudly in the right corner of Heinz's desk. "Yeah, exactly! Weren't you evil because you were so upset and angry over losing that train?" Phineas asked. "You have it now! Dr. D gave it to you! There's no reason to be evil anymore!"

"You really are a naive child, aren't you?" Heinz rolled his eye. "You don't need a reason to be evil. Sure, the anguish over losing my beloved Choo-Choo caused me to become bitter, ruthless and cruel. But once you have a taste a power it's hard to let it go. Getting Choo-Choo back was great, but not entirely worth relinquishing my hold on the Tri-State Area."

"You seem to be doing a decent job of regaining power," Phineas bit out. "But it won't last for long. The Resistance will stop you, just like they did before."

Heinz leaned over his desk, an eerie smile curling across his scarred face. "And that's where you come in."

An icy feeling spread through Phineas' chest as the dark eye of Heinz bore into his own navy ones. "We're not going to tell you anything about the Resistance."

Ferb nodded firmly, glowering up at the man.

"Of course you're not. You're much too good to do something as awful as betrayal," Heinz remarked, easing back into his leather chair. "Torture won't do anything, either. You'd both rather die than sell out your friends." He spit the last word out as if it were acid burning his tongue. "But that's not why I brought you here."

"Then what is the reason?" Phineas demanded, tired of beating around the bush.

"You have made quite an impact on the Resistance here. I've heard rumours that their leader is stone-cold, and yet you managed to convince them to bring you down to the bowels of my lair so that you could rescue your pet platypus."

"That doesn't mean anything," Phineas protested. "She made that decision on her own accord!"

"Ah, so the leader is a female, eh?"

Phineas bit his lip hard, cursing his loose tongue.

Heinz mulled this over for a moment before returning back to the matter at hand. "On the contrary, for her to stick her neck out for two strangers not even belonging to this dimension means she took a liking to you. And if she has taken a liking to you, then she won't strike if she knows that you'll be in the crossfire-especially if she knows that I won't hesitate to beat you within an inch of your life if she or you two try something."

"So, what? Are you going to throw us in a cell and keep us there for the rest of our lives?" Phineas asked, trying to be brave.

Heinz smirked. "The Resistance has proven that they can slip past my defenses and intrude on my property, so it wouldn't be safe to leave you alone. Normbots, frisk."

Phineas yelped as he was jerked by his shirt collar, slamming into the hard metal of a Normbot. Within seconds, all of the tools he had stashed in his pockets were thrown into a pile on Heinz's desk. Ferb stared in dismay at the pile of screwdrivers, hammers, wrenches and Swiss Army knives.

"First, we have to clear you of any and all weapons." Heinz swept the pile into the top drawer of his desk and locked it. "Second, we have to make sure that I know where you'll be at all times."

"Hey!" Phineas cried as his Normbot swiped the bracelet off of his wrist. "What are you doing?"

Heinz snorted as he collected the pieces of technology. "Oh, please. You think I don't know O.W.C.A tech when I see it?" He studied the metal bracelets and the coloured buttons. "If your Francis Monogram is as uptight as mine, then he would have gotten his little intern to put tracking devices in them."

Judging by Phineas' silence and Ferb's lowered gaze, he decided was right.

"Perfect! I'll just have to make a few modifications and they'll be ready for you by morning." Heinz shoved the two bracelets into his lab coat pocket. "Until then, you will be staying in a cell. I sincerely doubt the Resistance is stupid enough to make a move on the first night of my re-takeover."

The Normbots snatched Phineas and Ferb up by the back of their shirts. From here they were level with Heinz's stare. He grinned wickedly at them. "Enjoy the night, boys. You'll be spending plenty of them here with me. I suggest you get used to it."

The Normbots took off, flying out of the skylight and towards the bank of steel-door cells located in the prison.

Phineas exchanged a glance with Ferb as they flew through the dusky sky. The one look was all they needed to express the thoughts they did not want to admit out loud.

Without their tools, there was no way to break out of the prison cell they would be staying in. And that meant their possible only opportunity for escape was thrown right out the window.

...

"Gee, sis, it's getting late."

Candace lowered her shades and peered down at her brother, who was staring up at her in concern. The dark bags under her eyes showed that she had not gotten any sleep the past few nights, and probably would continue to get little rest so long as Doofenshmirtz was in charge-again.

"If you're tired, I can escort you home," she offered. "With those stupid Normbots plaguing the streets again, I don't really want you going anywhere by yourself."

"No, it's not that," Phineas said quickly, adjusting the black headband over his buzz cut. It was strange getting back into the black uniform when all he had known were Dooferalls. "You look like you could use some sleep."

Candace smiled slightly and ruffled his hair. "There's no such thing as sleep when you're in a war, kid." She stepped past him and studied her headquarters intently.

Everything was still in working order, as they had only abandoned it for about two weeks. The computers lining the left wall showed every angle of the perimeter around Isabella's house. Dr. Baljeet's equipment hummed softly with energy as it hacked whatever systems its master ordered it to. "Dr. Baljeet, report."

"Other than the recent launch of hidden Normbots, there does not seem to be any other activity from Doofenshmirtz," Baljeet reported, scanning the multiple screens and grids intently. "However, his computer records show he has been looking into an abandoned factory just outside the city limits."

"It might be a ploy to lure us out of hiding," Candace said, eyes narrowing in suspicion. Since the Resistance was behind the defeat of Doofenshmirtz in their dimension, she had a feeling he was a little more aware of their capabilities. It would be a bit more difficult to find out what he was up to and they would have to study every piece of information with a critical eye.

"Well, he does only have a few dozen Normbots," Isabella spoke up. "He might want to use a factory to manufacture more of them since the O.W.C.A raided his lair and home."

"That's true," Candace agreed. "Dr. Baljeet, monitor all abandoned factories and even those still in use. Notify me when Doofenshmirtz starts moving in."

"Will do." Baljeet saluted and returned his attention to the screen.

"Gretchen, any news from Major Monogram?"

Gretchen glanced up from her laptop and shook her head. "No, sir. I've hacked into the security feeds from my laptop and the place is cleared out. They must have bailed just in time."

"Okay, that's good. It means we're not alone in this." Candace nodded, thankful for this small victory. "Major Monogram will probably settle in a base out of state and contact us when he's ready. He has our number, right?"

"Yes," Gretchen confirmed.

"Then we wait for his call. We won't compromise his mission for ours," Candace ordered. She turned her head and for the first time spotted Perry resting by Ferb's feet. "Has he been here this whole time?"

"No, he just got here," Phineas said, relieved that their pet had come back this time. "Should we keep him inside throughout this? I mean, the last time he disappeared was when Doofenshmirtz achieved power."

"He's an animal, so we can't keep him cooped up. Besides, he always comes back, even if it takes months." Candace answered. "So don't worry about it."

"Security scan complete!" Ginger called from her station. "All good so far on the home front."

"Okay." Candace nodded. "Alright guys. This time we're going to have to be very careful on who we talk to and what missions we pull off. No one does anything without my approval. We triple-check our surroundings before we come to base. We don't lose focus for a second. Am I understood?"

"Yes, sir!" the group of kids chorused.

"Good. Firestorm Girls, stay here for the night. We don't want to risk Doofenshmirtz coming after you again."

"Got it, Chief," Milly answered, secretly dreading a long night on a stiff cot.

"The rest of you, slip out the backway one at a time and go home for some rest. We meet back at here tomorrow at eight." Candace slipped the shades over her eyes and set her mouth in a grim line. "We have some serious busting to do."
