Description
Convincing Lawrence that they were heading out to search for Perry was the easy part; convincing Linda of the same thing was the hard part. The mother always needed a good reason for her children to be out at that time searching for their pet platypus, even if it was shortly after dinner. But Phineas' desperation and love for Perry soon won Linda over, and after clearly stating that she did not want them out any later than midnight—summer gave the boys a good excuse to stay up late—Phineas and Ferb gave their word to return by then and dashed up the stairs to the elevator Perry had built for them to give them access to his lair.

Arriving in the platypus' lair, the boys used Perry's fedora to gain access to the transport tubes that led to the OWCA's headquarters. Thanks to the fact that the computer system recognized nothing but the agents' fedoras—Phineas and Ferb had offered to upgrade that for them, but Monogram was hesitant in having children fix it up for the agency; well, he did have them upgrade the rest of the security system, just not that part—the boys were able to easily gain access to the transport tubes and were soon on their way, undetected.

Getting past the security cameras and making their way to Carl's computer lab was a whole different matter. Not only had Phineas and Ferb never been allowed full access to the OWCA's corridors, but animal agents, as odd as it sounded, had much better senses than humans did.

Luckily, Perry was the best of all the agents, so he had given the boys their own fair share of training; the only thing worrying them was the fact that he would not be there to correct their mistakes.

The boys dashed across another hallway and hid around the corner just before a camera turned its lens in their direction. They glued themselves against the wall and waited a few seconds; then, Phineas carefully peeked around the corner to make sure it had turned away. "Okay," he whispered as Ferb leaned towards him. "Carl's lab, according to this blueprint Perry gave us a while back, is right across the hallway…" He pointed at a door. "… Right there. We need to get in there for answers."

"Are you sure he'll still be working in there?" Ferb whispered back. "It's after work hours, you know."

"Carl's a hard worker, not to mention Major Monogram probably has him work overtime."

"… True, the man is a bit of a pain in the posterior at times…"

Phineas looked down both ways of the hallway for a moment before looking at the camera. The boys hid once more as it rotated and stared in their direction, and once it had turned away, Phineas and Ferb made a break for Carl's computer lab. "Crack the security code on the lock, Ferb," Phineas said hastily as his stepbrother approached the pad of numbers and began doing as he was told. "If we can get in easily, then the element of surprise will be on our side—!"

To their complete shock, the lab door swung open and a man with curly dark red hair and thick lenses made to exit the room; instead, he came nose-to-nose with the Flynn-Fletcher boys and immediately recoiled in surprise. Phineas and Ferb recoiled as well and looked on silently for a moment. "… So much for the element of surprise," Ferb muttered in his brother's ear.

Carl stared at them in silent disbelief before hastily digging into his pocket to grab the communicator. Phineas gave the word and he and Ferb grabbed the man's arms while pushing him backwards into the dark room. Carl yelped in surprise as he was forced up against the far wall by the two teenagers, and after shaking some sense into his head, he stared almost fearfully at the Flynn-Fletcher duo.

"We've got a feeling that this organization knows more about those dudes in suits, so spit it out now, Carl," Phineas said behind clenched teeth.

"I-I-I have absolutely no idea what you're talking about," the intern replied nervously.

"Come on, Carl, we're teenagers, not idiots."

"No, seriously; I have absolutely no idea what you're talking about!"

"Secret agent humans; white van, Perry is somehow a rogue agent—!"

"Oh, thaaaaat," Carl interrupted. He swallowed with difficulty and stared at the red head. "Uh, that's confidential, Phineas; I don't have permission to tell you."

"You do if he's our pet," Phineas growled. "Why did they take Perry away? Why is he a rogue agent? Why weren't we informed? Did we do something wrong? Did we say something? If we made some kind of mistake, tell us what we did!"

"Y-y-you and Ferb have done nothing wrong—!"

"Then why did they take Perry away?"

"I'm not at liberty to—!"

Phineas and Ferb pushed Carl against the wall even harder, making him yelp again. "Carl, you're telling two creative geniuses who helped save the tri-state area that you basically know nothing about our pet platypus, who happens to work for your agency," the red-head continued. "We know something's amiss when our pet goes missing longer than usual and when he refuses to come to us when we call. So please, for Perry's safety, tell us why they took him!"

"I-I'll lose my job if I tell you anything!" Carl whimpered. "M-Major Monogram isn't the biggest hearted guy, you know!"

"You don't get paid for your job, Carl, so what difference does it make?" Phineas' voice began to crack. "They shot Perry with tranquilizing darts and took him away inches in front of our faces! They even threatened us with guns! If you know anything about this, please tell us now! PLEASE!"

Carl stared at him in silence for a moment or two before looking at Ferb. Although this one hardly showed any expression on his face, as usual, the intern could clearly see the same worry in his dark blue irises as there was in Phineas'. He looked from one teenager to the next, wondering what he should do. But unlike Monogram, Carl had a soft spot for the boys who owned Agent P; he had seen their creativity first hand, he had gotten to know them personally, and he respected and even admired the relationship Perry had with them.

After a moment longer of indecisiveness, Carl rolled his eyes back and sighed in exasperation. "I am so dead," he moaned.

"If it makes you feel more secure, we won't tell Major Monogram that you helped us if we get caught," Phineas replied.

"Technically, that wouldn't work, since you don't know the security codes… only I do—!"

"17-94-37-10," Ferb interrupted unemotionally. After Carl looked at him in shock, he raised an eyebrow. "That's the code to hack the motherboard, and from there, I could get anything I needed."

Carl stared at him wide eyed for several seconds before opening his mouth. "How in the world did you figure that out?" he asked.

"Simple, really. On video feeds, I would watch your fingers type the code. It's… not that difficult, you know." Ferb tapped the side of his head. "A photographic memory helps too."

"That put aside, will you help us if we give you our word not to mention you?" Phineas repeated his plea. "You have our word, Carl… We just want to find Perry."

Carl looked at him again and was struck by pity once more. He moaned a second time. "Fine, I'll help you," he said with a sigh. "As long as Major Monogram doesn't find out." Once the boys released him, he dusted his white shirt off and walked over to his computers. "Close and lock the door, Ferb; it'll soundproof the room. We have several nocturnal agents, and it would be best if none of them find out about this."

As Ferb did as he was told, Phineas took a standing position behind Carl's chair when the man sat down. The curly-haired man punched in several codes quickly until the largest computer screen lit up. "A few weeks ago, some of our cleaners found evidence that Dr. Doofenshmirtz' amnesiainator had been tampered with," he said while typing. "We did DNA checking and found that it was platypus hair. And considering there's only one platypus who works for the agency at the time being—or at least, here in Danville—we immediately assumed that the culprit was Agent P."

"How could be sure about that?" Phineas wondered suspiciously as Ferb joined them. "Someone could have tampered with the machine and then planted those hairs there afterwards."

"We considered that, but it doesn't compute," Carl replied while turning in his chair and looking at the teenagers. "You see, the only one who knows exactly how Doof's inators work is Perry, and considering the changes that the amnesiainator had over gone, we concluded that it was him who tampered with it." The man turned back to the computer screen again and typed a few more codes until a folder with images of the inator in question appeared. "Anyway, since tampering with evidence and items that are officially OWCA property is a serious crime, especially for an agent, Agent P's been… well, his position has been terminated—!"

"What is that thing?" Phineas interrupted while pointing at an image of the amnesiainator. "I've seen most of Dr. D's stuff, but I don't think this one rings a bell… How 'bout you, Ferb?"

The green-haired sixteen-year-old shrugged his shoulders and shook his head. Carl looked at the two of them in surprise. "You mean you don't know what it is?" he said. "You don't… even the least bit remember what it is?"

Phineas and Ferb looked at him with uncertainty. "Uh, should we?" the red-head replied.

Carl tapped his chin thoughtfully. "Huh. That's odd," he said. "If Agent P tampered with the amnesiainator and gave you back your memories, I would assume that you—!"

"Wait, wait, wait; what do you mean gave us back our memories?" Phineas interrupted a second time while holding up his hands.

"Well, the reason Agent P tampered and permanently altered the amnesiainator was to give you and Ferb your memories back about the Tri-State Robot Riot."

"But that doesn't make any sense," Phineas replied with a confused frown. "Ferb and I have always remembered that."

Carl turned in his chair to face them. "No, you haven't, Phineas," he said.

"Yes, yes we have."

"No, no you haven't. Perry gave you those memories back."

Phineas fell silent for a moment before the confusion in his now dissipating frown filled his eyes. "What… what do you mean?" he asked almost meekly.

Carl passed a hand through his hair. "I can't show you the rest of the surveillance tapes from that day five years ago," he said, "Mainly because Monogram confiscated those himself… but I'll try to explain it without any visuals…" He placed his hands together. "The summer you guys traveled to an alternate dimension, we were forced to erase your memories so that neither you two, nor your friends, would remember that day."

"Who got their memories erased?"

"You, Ferb, Candace, Isabella, Baljeet, Buford, Jeremy… most of the kids you know… Doof did too, so that he wouldn't remember how to create the Other-dimensionator, or how to make his machines properly function."

"I often wondered why he kept failing if we had showed him that a self-destruct button wouldn't work," Ferb muttered thoughtfully.

Carl looked at him for a moment before rubbing his chin. "Hm," he said. "Maybe the reason why Agent P didn't give you two the memory of the amnesiainator back was because he wanted you two to think that you had never forgotten that day in the first place. That's plausible."

"But I… I still don't understand," Phineas said with a meek voice, catching Carl's attention; "Why did we have to have our memories erased?"

Carl looked at him pitifully. "It was either that… or else lose Perry forever." When Phineas and Ferb looked on in dismay, he continued: "Once an owner finds out about his or her pet's secret identity, if they have one, that is, we need to relocate the agent to another city and another family because their kids know too much. It could endanger their lives. Perry didn't want to lose you guys, and you didn't want to lose him, so you volunteered to have your memories erased instead of remembering the greatest adventure you ever had and losing your pet." He held out his hands. "Perry told us that you two remembered the events on your own, but we found out after the evidence on the amnesiainator that he was lying to us, just to keep from losing you two—!"

"Hang on a sec," Phineas said while raising a hand. "What if our memories never were erased? Did you think of that?"

Carl rolled his eyes tiredly and slapped his forehead. "Phineas, does it make any sense to you as to why you and Ferb are the only ones who remember that day, and no one else does? Why do you think Perry still acts like a mindless pet around your sister or your friends? Just for show?"

Phineas fell silent here. As he uneasily rubbed the back of his head and looked away, Ferb cleared his throat: "Then, if Perry really did give us our memories back, where's your evidence of that?" the English-born teenager asked while crossing his arms.

Carl looked at him for a moment before turning around in his chair. "Well, Monogram hasn't deleted Agent P's file yet, so there might be something in there," he said while typing. It took him a few minutes to locate it and enter the correct folders. "I have cameras in his lair in case you boys accidentally dropped in unexpectedly, but I never found anything over the years… All we know is that he gave you your memories back around the age of thirteen… that's when you two started remembering that day again, right?"

Phineas and Ferb nodded their accord. The intern nodded back before continuing his work. "Makes sense then; I checked the recordings from that summer, but found no recordings on one certain day. Considering how intelligent Agent P is, he could have undoubtedly removed that recording from the system, thus putting it into his file… Oh, would you look at that?" He leaned towards the screen and adjusted his glasses. "Well, whadaya know? There's a folder right there titled Phineas and Ferb Memory Evidence. Must be that one. Wonder how I never saw that before…"

He moved the mouse and watched it hover over the folder. But when he double-clicked over it, a box asking for a security code appeared.

"Ah, darn," the man groaned. "He probably put a password so that no one could enter it. That's just… fantastic—!"

"Uh, may I?" Ferb asked as he leaned over the keyboard. Placing his fingers over the keys, he typed in a word before pressing enter. Sure enough, the computer accepted it and the letters turned green.

"Pumpernickelplatypusterd?" Carl read aloud with a great amount of confusion in his voice. While Phineas covered a laugh behind his hand, the intern turned in his chair and looked at Ferb. "What in the world is that?"

Ferb smiled cleverly. "Perry and I play strategy games on a daily basis," he explained. "We tend to use codenames for each other on occasion. On a day we spent home alone at the age of thirteen, when Perry returned from a mission, we played a virtual game of paintball with Phineas. Perry's codename was Pumpernickel Platypus Terd. PPT."

Carl stared at him in complete and utter perplexity. "What?"

Phineas giggled and wiped a tear. "I was high on sugar that day," he said. "When Ferb said that we should have codenames, I randomly shouted out that name and it stuck. Perry's been using it ever since."

Carl blinked several times quickly before turning back to the screen. "I will not question anything," he muttered stubbornly. "Absolutely nothing." He hovered the mouse over a media icon. "Okay, the date that this was taken is the exact date that I got zilch on the security cameras in Agent P's lair," he began. "So this is undoubtedly the evidence that will prove to you that Perry gave you back your memories." He looked up at the boys after a momentary pause. "Are you guys ready to watch? It might shock you… If you don't want to, then—!"

"No, no, play it now," Phineas insisted while waving a hand before him. "I need to know what happened… and why Perry's been labelled a rogue agent."

Carl looked on for a moment longer before sighing and turning around. "Alright then." He doubled clicked on the icon and waited for the video to begin playing.
