At D.E.I (Doofenshmirtz Evil Inc) the teenagers were in the living room, talking while opening packages of chips and popcorn, drinking soda, scrolling through their cell phone screens and waiting tediously for Vanessa to choose the movie.

"So... I thought we planned to watch this foreign art film that I found" Vanessa said, placing a DVD box on the coffee table, drawing everyone's attention.

"Le Coeur Noir De Douleur et de la Tristesse Douce." She thought about the complicated title.

''I'm not even going to try to say that...'' Dana said, laughing while Vanessa take the disc for the DVD player.

"Hmm, looks cool. Is it animation ?" Candace said innocently, making the other girls look at her.

"So, Clarice, right ?" Lacie asked the young teenager.

"Candace, actually..." She corrected, thinking about how she could have misinterpreted her name like that.

''You seem very young to me... are you sure you'll be interested in films like that ?'' Asked Lacie, imagining that a film like that, wouldn't be ''fun'' for someone like her.

''I want to try new things... besides It was better than being alone'' Candace said, not caring if it was boring or fun, just wanting to fit in.

As the girls were talking about their favorite rock band or clothes, there was a knock on the door, but before anyone could respond, Dr. Heinz Doofenshmirtz walked in, announcing himself.

"Greetings, ladies, I made a doonkelberry pie for movie night!" He said happily, with the dessert in his gloved hands.

''Dad!'' Exclaimed Vanessa, placing the controller on the table and quickly walking over to him.

"I thought you were going to stay up there!" She said, making the smile on her father's face disappear.

''I was... just thought in check out my reason for living and her friends'' He said, looking around... expecting at least a ''thank you'' from his daughter.

''Dad, that's nice, thank you... but we already have snacks" She said, trying to praise his hard work, knowing that pie wasn't a easy task, but every piece was worth it.

"But, honey, it's your favorite" Heinz said, knowing there was no way she could resist it.

''And snaks are never too much, look at you, so skinny" Pointed him to her belly, making his daughther a little irritated.

''Fine...'' She said, bringing a wooden rest, placing on the center table and Heinz placed the dessert on top, attracting looks from the other girls.

''But please..." She continued, pointing to the door with her eyes, gesturing something that Heinz knew what it was.

''Okay... I get it'' He said, scratching the back of his head, quickly looking at the TV.

"Are you watching your mother's foreign films ?" Doof asked, confirming the movie he watched with Vanessa's mother when she was younger.

''I remember this one, it's kind of sad and will probably bore you to death, there's a better option-'' Doof Said trying to fit himself into the conversation but was interrupted by his Daugther whos has another plans... and none of them involve his father.

"I appreciate the suggestions Father, but please..." She said, accompanying him to the door... almost like its was pushing.

"Sorry... I'm leaving, Vanessa'' He said with a sad semble, walking to the door.

''Need to go back to Perry, the platypus... he problably still in my trap'' He assumed, opening the door.

''Thank you for the pie, Mr. Doofenshmirtz... it looks delicious'' Said Candace with a smile.

''Don't mention, Darling... enjoy the movies'' He said closing the door while sighing heavily and walkign up to the stairs.

''Your dad seems cool, Nessa, reminds me of mine...'' Said Candace, remembering that her father, James Flynn, that also knew how to make a great chocolate cake... well, when he had the time and the last time she saw him, was hugging Linda, her and Phineas, while carrying a big backpack.

''I'll try be back for Christmas, okay ?'' Was the last thing he said, dressed in camouflage combat gear, with an American flag on each shoulder, Phineas was too young to understand what was happening... so was her.

''Are you okay, Candance ?'' Dana asked, seeing the brightness of the TV illuminate the eyes of the old Flynn, which seemed much more teary than normal.

''Of course... it's nothing, my bad to ruin the mood'' She said turning her face away and wiping the tears trying to forget those horrible memories.

''Come on... you're not ruining anything'' One of the teenagers said, with a hand on Candance's shoulder.

Feeling tired Doof walked back into his lab to turn off the disco music, expecting his nemesis to be trapped the same way he left him.

"Okay, Perry... lets finish this up al-'' Doof was cut by Platypus who knocked him to the ground, after giving a backflip and spinning his stick.

''Arg... So that's how gonna be ?'' He asked massaging his face while seeing the platypus getting into a fighting position.

''Fine... met my friends Poly and Ester'' Heinz said, taking two pillows, making Perry look at him like ''Aren't you even going to give me a challenge ?''

''I already said I don't want to bother the girls... you don't want to see Vanessa angry''Heinz said, remembering how much his daughter reminded him of his ex-wife when she was angry.

Without saying another word, Perry and Doofenshmirtz began their silent combat, blocking the scientist's attacks was no problem for the Platypus... Doof landed a lucky attack on Perry sending him flying but grabbing a cable, he managed to do a somersault and return to the scientist, hitting him with the bat, making him throw one of the pillows. However, the pilow hit the machine, causing it to activate and release some sparks.

''It's overheating, we have to get away quickly !'' Heinz said, getting up and running to a nearby table, taking cover when drop it, Perry went towards him, also using it as cover.

But the machine just fired a single shot, hitting Roger who fell to the ground, soon a crowd of worried people, formed around him.

Heinz approached the balcony to see if it had worked and taking his lunette, observed what kind of horrible monster his brother had transformed into in... and to the irony of fate, Mayor Roger transformed into Heinz's clone, grunting with difficulty "Lots of me, Lots of Me''

''Ah, how funny, its the universe making fun of me again...''Heinz said, watching Perry arriving in slow steps, and both turn their eyes to the machine, that has more sparks coming out.

''Stand back Perry, it's going to explode'' Heinz warned the Platypus, that made a somer sault and landing exactly on the ''x'' painted on the ground, then a cage captured the him, raising at Heinz's height.

''Typical...'' The scientist continued laughing as he touched the cage with his finger.

''The OWCA didn't train you very well, did it ? You really think it was going to explode ?'' Heinz asked, mocking the agent's skills, and looking at his glorious invention that as soon as he finished his speech, exploded like all the others.

Perry couldn't help but hide his laughter, thinking that it didn't matter... Heinz was doomed to failure, which was funny and sad at same time.

''Well... it doesn't matter, I got my target'' He said, trying to hide his nonconformity and turning his attention to his brother, trying to appreciate his ''success''.

''And look h-'' Heinz interrupted himself, seeing that now there was not just one of him... but several, the infected were touching several citizens, and turning them into copies.

''Well... it wasn't part of the plan but I think it works'' Heinz said, taking Perry's cage, ignoring the several screams of people who were turning into clones... starting a contagion throughout that area.

Not far from there, the boys had already exhausted their energy, finding themselves now resting on a sidewalk while Phineas and Ferb went to get some snacks and drinks.

"That's what I'm talking about !" Phineas said, tossing Buford a bag of sandwiches, knowing that was nothing better to enjoy the rest of the day.

''Leave one for Isabella, Buford'' Phineas said, sitting on the floor, as he drank his juice.

''What a day, guys'' Baljeet said as he took a bite of the sandwich, just below one of the lights, knowing how incredible they reached places that normally only a chooper would reach.

None of them were conscious of this, but Isabella watched them from the top of a building, her back against the concrete wall, while she dangled her legs.

''They're right, I have nothing to lose'' She thought, standing up, feeling her confidence reach a level where she no longer felt fear or doubt, just determination.

''All or nothing...'' She said, closing her eyes, letting herself fall backwards, bouncing on the street, doing a flip and stopping right in front of them.

''Wow'' All the boys said, applauding the Fireside's acrobatic techniques.

''Thank you, everyone...'' Isabella said, making a reverence in gratitude.

''Isa, you must be tired, Buford has one last snack... just for you'' Phineas said, giving her some space between him and Ferb, impressed by her surprise entrance, it was the second time today that she caught him by surprise.

''I appreciate Phineas... but I'm not hungry, I actually need to talk to you... It's kind of important, so do you mind if we're more private ?'' She said pointing to the building she came from, extending her hand towards the triangular inventor.

''Of course'' He said, throwing away the packaging, accepting her hand and the two jumped high to go to the building above.

''Do you think the girlie will have the courage this time ?'' Buford asked, biting the sandwich intended for her, while Baljeet and Ferb remain in silent, knowing that maybe, this can be just one more on the list.

''Okay, we were here'' Phineas said, landing on the edge, wondering what could be so important.

''What do you want to talk about, Isa ?'' He asked, sitting on the ledge of the building looking at the illuminated city, thinking how beautiful it was, not imagining the storm that was coming on the horizon.

''Well...'' She said, sitting down next to him, taking out the badge from her pocket.

''It's about the Emotional Bravery patch..." She began her explanation, looking at the city lights and then at her beloved boy, but to their surprise...

"No! No! Get away from me!" A frightened voice made both of them turn around immediately.

''I know that voice...'' Isabella thought, putting the emblem back on her belt, standing up when she noticed that it was a female voice, and from the tone it seemed to be an elderly woman.

''Mrs. Feyersied ?" She asked herself, hearing her screams once again, it could or not be another hallucination, but she would never mistake that voice, even more so screaming for help.

''Phinny, I'm sorry, but I need to check what that scream is...'' Isabella said, jumping from the building.

''Wait...'' He said trying to stop her but she was already far away.

''I'll be back in a second !'' Isabella said from a distance, holding on to some power cables, doing an acrobatic and bouncing on the ground, starting to follow the sound of screams.

Soon approaching the founder of her troop, she did one last somersault, landing a few feet away from Mrs Feyersied, beginning to walk before show her the scout badge, like a police officer.

''Good night, ma'am! Fireside Girl Isabella Garcia-Shapiro Troop 46231'' Isabella said, helping the elderly lady get to her feet

''What's the emergency?" She asked, don't understanding the reason of such panic.

"PHARMACISTS! PHARMACISTS!" She screamed, fleeing the scene in despair, followed by some other citizens who were as terrified as she was.

''Pharmacists... I didn't know she was afraid of hospital too'' Isabella said, watching her walking away, not sure what she meant by that.

Passing the scene for the boys not far from there.

''And when she was about to tell me something, we heard some screams...'' Phineas said as he saw people passing by him running, scared by something unknown to them.

''Like these people... where she can be ?'' He asked, seeing his friends land next to him.

"And what's the reason for all this rush..."

''Perhaps that ?" Baljeet pointed worried, towards the direction of the unknown threat.

"Irving ?" Phineas asked, wondering why they would be running from him: not even a baby would to that... I mean what threat he could provide other than questions... a lot of questions.

"Hey guys, what's up ?" He said with a smile.

"Not that, genius! that!" Baljeet said, pointing to the other side.

''Ah, zombies...'' Phineas said, nodding in a calm statement, seeing the zombie-like creatures bumping and touching innocent citizens who immediately turned into more clones, murmuring "Lots of me, lots of me..."

''ZOMBIES!'' The boys said at the same time, feeling panic when they knew what that meant and began to walk away, seeing the terror of the citizens screaming and fleeing the place as quickly as they could.

''IRVING, GO TO A SAFE PLACE!'' Phineas shouted, pointing in a direction he thought was safe and they started jumping, Phinea's last sight was Irving running towards a nearby building.

The boys jumped to the nearest safe place in hopes of hiding, soon finding a cover behind a brick wall and as they breathed heavily, tried at same time assimilate what was happening.

"Who're these guys?!" Buford asked, still catching his breath.

"I don't know... It's some kind of... pharmacist." Phineas guessed, thinking it was because of the white coat.

''But a lot of people wear white coats, doctors, nurses, veterinarians and scientists...'' He thought that maybe they could be something else... but that didn't matter now.

"I think if he touches you, you'll become one of them too !" He said, remembering the way he touched one of the citizens who turned into a clone, knowing that these ''zombies'' didn't look like any other zombies he had seen in Hollywood films.

"But I can't be a pharmacist! I don't know anything about medicines, besides, have you seen how ugly they are ? I can't become that" Buford exclaimed.

"Let's also agree that being handsome isn't your strong point anyway'' Ferb said getting a sideways look from Buford.

''Guys, we have to make sure these things never touch us!" Baljeet said, not noticing one of the zombies sneaking up behind them that grabbed the boy by the neck.

''NO LEAVE ME !''He shouted in terror, looking into the eyes of the infected and seeing nothing in his soul.

''LEAVE MY NERD ALONE'' Buford said, punching the pharmacist, making him release Baljeet, who fell to the ground.

''I'm the only one who can do this'' Said the bully, continuing to punch the pharmacist until a trash can flew by and hit the infected, making him fall to the ground, unconscious.

Turning around, Buford saw it was thrown by Phineas and Ferb and from the ground the Bully picked up a piece of wood.

''Jeet, are you fine ?'' Buford asked, holding a piece of wood like a baseball bat, imagining that the nerd was infected.

''I'm fine... Im fine ? Why am I fine ?'' He asked to his friends, touching his own chest, noticing his heart beating faster, receiving help from Phineas and Ferb to get up.

''I don't know... we're aiming at Buford anyway'' Phineas confessed, trying to understand why his friends was imune to the zombies.

''Why me ?'' Asked the Bully, who's received some looks of Phineas and Ferb, even Baljeet, that afther some seconds Buford compreed what they're meaning.

''Its fine Buford... You follow your instincts, not considering the fear, everything to help me, so thanks, it was nicest thing you've done for me''

''That's what's friends are for...'' Said Buford nodding.

''But why we're imune... '' Baljeet asked, still puzzled as to why he and Buford weren't among the zombies.

"Maybe our rubbery skin is acting as an insulator" Said Ferb, remembering when an infected touched someone, small lightning bolts could be seen.

"So Contagion must be transmitted by electrostatic charge... rubber isolates static electricity !" Phineas said, looking for a logical solution to all this madness.

When turned around, the boys realized that they were being surrounded, but still had the rubber effect in their favor, opting for the first and only option at the moment: "Let's jump, guys!"
