Chapter 3

"…and the closer the person being blasted is to the –inator, the stronger impulse they will get to fall asleep." Perry had just woken up from his nap when he found Doof still explaining his scheme. "And so, with everyone wanting their bed more than anything else, I will be free to waltz in and take over. Then when they wake up the next morning, they will find that I, Dr. Heinz Doofenshmirtz, will be supreme ruler of the Entire TRI-STATE AREA!" matching is enthusiasm from before. Perry, on the other hand was barley listening. He wanted to finish this up quick as the routine that he and Dr. D had got in had become too predictable, and not for the first time. Doofenshmirtz noted the faraway look on his face and he didn't appreciate it. "Perry the Platypus!" Perry jumped, not expecting Doof to raise his voice. "You weren't listening again?!" Perry gave an apologetic look to Doof but he was having none of it. "You know if you won't take the time to listen to my evil scheme, then I won't wait for you to break free from my trap. I'm just gonna, continue my evil scheme, with or without…" Just then he stopped for a ring at his door. "Oh, hold on Perry the Platypus." Perry tried to look towards the door but the chair was bolted to the floor. All he heard was Doof opening the door and a voice that made him freeze up.

"Fireside Girls!" Isabella squealed in her cutest voice. Perry instantly knew this was Isabella and he also knew that she would recognise him the moment she saw him. Although his cover was under threat, it was also exciting. A chance to mix up his and Dr. D's routine that he desperately needed.

"Ah, of course" Heinz replied "Do you have my cupcakes?" he said excitedly.

"Ah, of course" she said, copying him. Heinz did not like people mocking him as he stated in an earlier backstory, but as long as he was getting cupcakes, he didn't take much notice. "Say? Do you have a daughter? She said while getting the cupcakes out of her bag, trying to sound as innocent as possible as there was something about this guy that made her try not to annoy him.

"Have you been stalking me?" he replied, his right hand moving out of her view and grasping slowly for a ray gun looking device behind the door.

"No, no. It's just I met someone called Vanessa a while back and I was just wondering if she was related to you." She said, not wanted to upset the man. As much as he loved evil and hurting others, there was something about a fireside girl that reminded him of his daughter when she was their age. He wished that she would have joined the Fireside Girls ages ago but she wanted nothing to do with him and her personality didn't change when she entered her teens. He thought to himself 'I'll call Vanessa over here and if she doesn't recognise this girl, I'll blast her with my Away-inator'.

"Hey Vanessa!" he yelled into the next room "There's a Fireside Girl here for you!" He turned to Isabella. "She'll just be a moment" he said nervously, beginning to feel embarrassed about exposing his personal life. A minute passed before a door swung open and a tall, brunette teen covered in black leather approached her dad. He could see that she was in a strop and he defiantly didn't want an argument with her in front of someone.

"Daaaad! I already told you I don't want to be a Fireside Girl, besides I'm too old!" her tone towards him as bitter than ever.

"No,no,no. I've got that conversation marked up for Wednesday. No. This Fireside Girl says she knows you." He stepped back and allowed Vanessa to see the small child in front of him. Isabella saw from her expression that she was having trouble placing her face, so she decided to speak, hoping that would jog her memory.

"Don't you ren…"

"Your one of Ferb's friends aren't you. I'd recognise that voice anywhere. What do you want?" she asked obviously remembering her from their crash landing in Paris.

"Can I talk to you?" While Vanessa would not normally hang out with people Isabella's never mind a Fireside Girl, it would be nice to have some 'Girl talk' with someone other than her mom. Both Vanessa and Isabella looked towards Doof for approval.

"Go on then" he said knowing full well he had trouble saying no to Vanessa when she gave him those puppy dog eyes from when she was ten years old. He began to reminisce about her childhood when a word snapped him out of his trance. "Wait a minute. Who's Ferb? He shouted as she ran into her bedroom with Isabella in tow, not wanting to talk about guys to her dad.

"Not now Dad!" was all she said before closing her bedroom door.

"Alright but we're eventually gonna talk about this!" was his final words to his daughter before returning to Agent P. "Sorry about that Perry the Platypus. You know… Family" he shrugged before getting back to work on his evil scheme.

Back at the Flynn-Fletcher house, their machine was almost complete thanks to the added help of Baljeet and, to a lesser extent, Buford. Just as Ferb was adding the finishing touches to the contraption, the fireside girls entered their backyard.

"Hey guys, what you up to?" said Gretchen, walking in first.

"Well, we've just completed a machine that shows everyone' most powerful love and traces it back to the moment it first came into being so we can discover what is love and what makes it." He said quickly, thinking that he wasn't complicating it for anyone. The Fireside Girls only had to hear the word 'love' to answer their questions on Isabella's abnormal behaviour. "What you girls up to?"

"Well" began Holly, who came in after Gretchen, "We came over to help you build it, but it looks like you've already done it so…"

"You could always help us test it. The more tests we do, the more conclusive our research would be." Phineas always wanted more of his friends to partake in his big ideas. Things were more fun that way. As the Fireside Girls agreed to test the machine, Buford jumped to his feet.

"Hey, where's Isabella?" He looked towards the others with a smile on his face, as if to say 'How clever am I?'

"Well she wanted to go…" Adyson was soon cut off by Buford.

"No, no. It's a rhetorical question like; Where's Perry?"

"Hey, where is Perry?" Katie asked.

"We've already done that bit" mumbled Ferb under his welders mask.
