I actually thought of this before writing Lake Nose Monster Things Take A Turn for the Worst. After writing it, I was inspired to write this one next. Bear with me as I try out another brotherly fight, eventually leading to some brother only fluff. :)

Btw... Ferb is 16, Phineas is 15 and Candace is in college...

I do not own P&F.

"What to do? What to do?" Phineas spoke while rubbing his chin. His older brother Ferb sat next to him underneath the large tree, reading a book.

The two were trying to come up with something cool to do this summer day. So far, they've got nothing. After spending years of summer doing awesome things, they're starting to run out of ideas. They've done a couple of repeats, just so they could build upon them but today… Phineas felt like doing something different.

The front gate opened up, and a familiar girl from across the street walked over.

She smiled sweetly, "Hey guys… whatcha doing?"

Phineas smiled wide and scooted over, "Hey Izzie, Ferb and I are still trying to decide what to do. But now that you're here, I'm sure to get inspired now."

Isabella and Phineas had both tried out the 'dating' world together, thanks to Ferb, and were now an inseparable couple.

Isabella sat in between the brothers, but leaned over closer to Phineas. He kissed her lightly on the forehead before getting back into his thinking mode.

Isabella tapped her chin, "Have you guys done anything with invisibility recently?"

Phineas shook his head, "No we haven't, but we already turned ourselves invisible last year… twice."

"Oh yeah, well what about a cool ride or something?"

"You mean like another roller coaster? We did that already twice as well."

Isabella shrugged, "Well there are other cool rides out there… like you know the scrambler at the fair. How it only goes from side to side, maybe you could do something like make it go upside down and-"

Phineas's eyes lit up, "That's not a bad idea… I mean, they're fun in all. But I bet Feb and I could make them even more interesting. Right Ferb?"

Ferb glanced over at his brother and nodded.

"It's settled then… Ferb I know what we're going to do today!"

About an hour later, the boys had a huge scrambler ride in the backyard. Isabella had called Buford and Baljeet over to if they wanted to ride it when it was finished. They came over in less then five minutes and watched as the boys worked. Phineas twisted something one last time with his wrench and dusted off his hands,

"There we go… that should do it."

The ride looked like normal scramblers, but when you climbed into your own pod, you had your own controls to control how fast or slow you want your pod to move, or if you want it to go up and down as well.

Phineas was about to ask everyone if they were ready to ride it, when Ferb came walking out of the house carrying a heavy looking object. When Phineas saw it, he raised an eyebrow,

"Ferb why are you bringing that out here? We don't need it."

Ferb just shook his head and began to set it up. Isabella walked over to Phineas and asked,

"What exactly is it?"

Phineas sighed, "It's Ferb's homemade stabilizer. When you turn it on and keep it pointed at something, it stabilizes the object or person it's focused on. I have no idea why he's using it on our ride."

He walked over to his brother, "Ferb is this thing really necessary? I mean the ride is safe enough… I checked it over twice."

Ferb flipped the switch and looked up at Phineas, "Just using it just in case… I promise you won't even know it's here."

Phineas frowned slightly, "I just don't think it's really essential, maybe we cold try the ride out first and then if it jostles a bit, then we can turn it on for the next ride."

Ferb shook his head and stood up.

"No? What do you mean no? You're supposed to agree with me on everything."

Ferb raised an eyebrow and shook his head again.

Phineas's mouth dropped wide open. How could his brother not agree with him… this was a first. Phineas crossed his arms and replied,

"Well I don't think it's needed."

Ferb crossed his arms and looked sternly at him, "Doesn't matter… I'm older then you, therefore I'm responsible of you…"

Phineas winced at this. Ferb almost never plays the 'I'm older then you, do as I say' card. But now that he has, Phineas feels a little mad about it.

Before Phineas could think of some sort of comeback, Buford shouted over, "If you two ladies are done fighting, can we ride this thing before we all start growing beards?"

Ferb looked warningly at Phineas once more, before picking up his tools and putting them away somewhere they wouldn't get stepped on or anything. Phineas glared as his brother's back and looked at the stabilizer. Isabella walked over and put a hand on his shoulder,

"What's wrong Phineas?"

Phineas sighed, "It's nothing really… just the fact that Ferb thinks we need the stabilizer is bothering me. I mean, I don't think we need it, but he thinks we do. I'm just kind of shocked that he doesn't agree with me."

"Ah Phineas I think he's just trying to be safe. The scramblers at the fair tend to shake people up quite a bit, sometimes hurting their necks or something. I'm sure he's just trying to make sure this ride won't do the same thing."

"Yeah… I guess you're right."

Isabella smiled and walked over to a pod. Phineas glanced around once to make sure no one was watching and slowly flicked off the stabilizer. He looked around for Ferb, and saw him climbing into one of the pods. Phineas quickly stood up and ran into the last empty pod. Ferb shot him a forgiving smile, so Phineas knew that he didn't see him turn off the stabilizer. Phineas smiled back and started buckling up his seat belt. Once everyone was buckled in, Phineas shouted out,

"Well if everyone's ready, I'm going to start it up. And if you need to stop or anything, press the small blue button. It's an intercom so I'll be able to hear what you guys need. Everyone ready?"

Everyone shouted out 'yeah' so Phineas flipped the switch that controlled the ride and watched as it started up. Once it was at a fast pace, the kids began to flip around and move up and down. Everyone, except Ferb, was screaming out excitingly as the ride continued. Phineas laughed, and couldn't help but think how silly Ferb was being. The ride is perfect, no glitches whatsoever. Boy, were the two of them going to have a good laugh when they get of this ride.

As the ride continued on, Isabella started feeling a little dizzy. She stopped flipping around, when suddenly she was jerked to the side, then to the other side. Her body was getting thrown around like a ragdoll, and it hurt. She reached out to push the intercom system, but kept getting pushed around too much.

Ferb could tell that something was wrong. Either they were getting sloppy with their building, or something was wrong with the stabilizer… the ride should not be this bouncy. He was suddenly scared when he felt his head being thrown against the window of the pod. He pressed the button on the intercom,

"Phineas… stop the ride."

Phineas pressed the button to reply, "Ferb we're just getting started, besides everyone is having a blast."

"Phineas do as I say now…"

"Ferb I'm sorry but you're not the boss of me, so I don't have to do anything you say."

"Damn it Phin, look at Izzie! She's getting hurt!"

Phineas looked at Isabella's pod, and saw her getting whipped around. Phineas gasped and quickly shut off the ride. Once it stopped, he unclipped his seatbelt and darted over to Isabella's pod. He climbed up, unbuckled her and helped her to the ground. She gripped on his shoulder and looked around dizzily.

"Isabella," Phineas spoke, "are you alright?"

She nodded her head, "I… I think so… my necks a little stiff, but I should be alright…"

Buford and Baljeet ran over. Buford crossed his arms, "What's with the short ride? It usually last's twice as long."

"Sorry guys," Phineas replied, "something must've been wrong with Izzie's pod, she kept getting whipped around."

While they all conversed, Ferb had hopped out of his pod to inspect his stabilizer. He scratched his head when he saw it wasn't working… or was it? He noticed the switch was flipped off, so he flipped it on. Sure enough, it sprang back to life. He flipped it back off and looked over to where Phineas was standing. He didn't… did he? Why would he...? Ferb whistled and motioned Phineas to come over.

Phineas walked over, "Isabella's neck is a little sore, but a least she didn't get whiplash."

Ferb crossed his arms and motioned to the stabilizer.

"What? What about it?"

Ferb narrowed his eyes.

"Okay, okay I confess… yeah, I did kind of shut it off, but it's no big deal-"

"No big deal?" Ferb spoke out, "Isabella got hurt, and that's not a big deal to you?"

"Well… yeah of course it is, but-"

"Unbelievable… you're unbelievable! I told you how I felt about using the stabilizer, yet you still somehow had the gall to flip it off anyway."

"I'm so sorry Ferb, look next time I'll listen, I promise."

"No! Don't you dare promise me that! You've never listened to me in the past, you won't start listening to me now."

Phineas crossed his arms, "That's not fair… I do listen. I listen to you when you have a problem."

Ferb rolled his eyes, "I mean you don't listen to me when it comes to our projects. It always seems like the choices are it's either your way, or it's your way!"

"My way? Ferb come on, that's ridiculous…"

"Okay fine prove me wrong, when was the last time we used one of MY ideas on a project."

Phineas thought for a moment and realized that he was coming up blank. He sighed and slumped his shoulders,

"I've got nothing… I didn't even know you had ideas..."

Ferb nodded his head and turned around, mumbling under his breath.

Phineas raised an eyebrow, "What did you just say?"

Ferb shook his head, but Phineas pushed even more, "No, no, no… I want to hear what you said."

Ferb sighed and turned around, "I said that I wish you weren't so irrational all the time."

"Irrational! Me? Ferb come on, you're being silly."

Ferb looked down at his feet and whispered, "Look Phin… I don't want to fight, okay? Not in front of our friends."

"So stop disagreeing with me about this!"

Both brothers started to stare each other down. Isabella, Buford and Baljeet watched uncomfortably from afar. None of them even noticed that ride suddenly flashed and disappeared.

Ferb crossed his arms, "I'm only disagreeing with you because it was wrong of you to unplug the stabilizer behind my back. Especially since I was using it for safety measures."

"I only because it 'ruined' my image of how the ride should look."

"That's the most ridiculous thing I've ever heard! Why can't you just listen-"

"You know what? Why don't you do what you do best… and SHUT UP?"

Everyone gasped at this. Ferb narrowed his eyes at his brother, who was glaring up at him. Ferb sighed and reached down to grab his stabilizer. Once he grabbed it, he pushed past Phineas and walked inside the house. Phineas turned around to look at his friends and shrugged when he saw their faces.

"What? What are you guys looking at?"

Baljeet started backing away, "I uh… think I hear my mom calling me."

Buford followed him out, "Mine too…"

Isabella looked sadly at Phineas, "Don't you think you were a little-"

"A little what?" he snapped,

Isabella's grew wide slightly when he snapped at her. She sighed and leaned up to give him a kiss on his cheek,

"Bye Phineas… call me later…"

After she left Phineas looked around and noticed that the ride was gone. He sighed and sat down next to the tree. He wasn't being ridiculous, the ride woud've probably been jostling around even with the stabilizer. Ferb was making a big deal out of nothing...

Back upstairs, Ferb had just finished closing the bedroom door, pushed the stabilizer back into the closet and flopped down on the bed. He buried his face in the pillow and tried to ignore the pain in his chest. What Phineas just said to him right now hurt... it hurt a lot. His own brother had told him to shut up, he's never done that before. And all Ferb was trying to do was look out for the well being of his friends and brother. And how does he get thanked for it?

He took his head out of the pillow and rested his head on his hands. His eyes were puffy from crying just now, and his frown was more sad then neutral. He heard his mom calling up to him and telling him that dinner was ready, but he wasn't hungry. Yet he forced himself off the bed and dragged himself out of the room. He stopped by the bathroom so he could splash some cold water on his face to get rid of the evidence that showed he was crying before walking down.

Once he was downstairs, his father was just walking through the door. When Lawrence saw him, he smiled,

"Hello son, did you have a good day?"

Ferb shot him up a fake smile and nodded his head. Lawrence tousled his son's hair before walking into the dining room. Ferb followed his father and glanced up to see Phineas already sitting down. Phineas looked up at him for a second, before turning his head away. Instead of taking his usual seat beside his brother, Ferb pulled out the one that was right across. Linda came walking in with a pan of food and set it on the table. She smiled at her husband when he walked over to hug her,

"Hi sweetie how was your day?"

He smiled, "Much better now that I'm seeing you..."

Both parents sat down with their boys and began piling their plates with food. After everyone had their share, Lawrence looked from one boy to the other,

"So how did everyone's day go?"

Phineas pushed his food around with his fork and mumbled, "Fine..."

Ferb just shrugged and took a bite of food.

Linda looked confused as she looked at each of the boys, "Um... okay is something wrong you two? Phineas you'd usually be excited to tell about your day."

Phineas didn't look up from his food when he spoke, "Because it wasn't very exciting..."

Lawrence frowned, " And why is that? You're not getting sick, are you?"

"You want to know why today was ruined?" He pointed at Ferb with his fork, "Ask him..."

Ferb looked up at Phineas and narrowed his eyes.

"Ferb," Linda spoke, "did something happen today that we should know about?"

Ferb bit his lip and looked back down at his food.

"Ferb," his father spoke, "your mother asked you a question, did something happen today that we should know about?"

Ferb looked back up at Phineas and frowned deeply, "I don't think I should say... considering Phineas told me to shut up."

Linda gasped, "Phineas?"

Phineas glared at his brother, "Only because you were being annoying!"

"I was being annoying? Do you even hear yourself when you speak, or does it come out as just 'me, me, me, me'?"

Lawrence's eyes widened, "Ferb?"

Phineas stood up from his seat, "Oh so you want to got there?"

Ferb stood up as well, "Maybe I do, what are you going to do about it?"

"Boys," Linda spoke up, "please sit down-"

"You don't listen Phineas!" Ferb interrupted, "You don't listen to anyone except yourself! Well guess what, you shouldn't do that because you're wrong at times!"

"You're one to talk!" Phineas shouted, "I don't listen to you because you don't say ANYTHING!"

"Me not talking is MY business, not yours!"

"That's enough," Lawrence spoke up, "both of you calm down and-"

"I know perfectly well why you don't talk!" Phineas spat out, "It's because your real mom used to tell you to shut up as well!"

"You leave her out of this!" Ferb shouted, "Don't you dare bring her-"

"I wonder if she got tired of hearing your stupid opinions as well! Because I know I am!"

"PHINEAS!" Linda spoke up, "Be quiet-"

"And you know what?" Phineas added, "I can see why your mother doesn't love you, and you know what? I envy her... I envy her because she doesn't have you around to kick around anymore!"

Ferb looked at him wide eyed for a second, before hopping unto the table, pushing Phineas back and unto the floor. Ferb began hitting and slapping as Phineas hit and slapped back.

"Take it back!" Ferb spoke in between his teeth, "Take it all back right now!"

Phineas spit up at him, "Never!"

"Why you little-"

Suddenly Lawrence was pulling Ferb up and away from Phineas, while Linda was pulling Phineas away from Ferb. Ferb struggled to get away from his dad, and felt hot tears streaming down his face. Lawrence gave Ferb a small shake before leaning down to his level,

"Ferb Fletcher that is enough!"

Phineas looked angrily at Ferb, "Just wait until I get my hands on you!"

Linda held him by his shoulders and spoke sternly, "Phineas Flynn stop this right now!"

"I hate you Ferb Fletcher! I hate you so much! And I wish that you weren't my brother! I wish you'd go back to England where you belong!"

Ferb suddenly froze and looked deeply hurt by what Phineas just said.

Linda looked angrily at her son, "Phineas Reed Flynn you apologize to your brother at once!"

Phineas looked up at his mom, "Why should I? Besides if I did, I'd be lying... and you've always told us that lying is bad."

Ferb's bottom lip trembled at this. He pulled out of his dad's grip and raced out of the room.

"Ferb!" his father called out, but Ferb ignored him. They all heard the distant sound of a door slamming and then silence. Both parents looked down at Phineas crossly.

Phineas looked up at them and knew by their faces that he went to far with his shouting and he was going to be yelled at by them now...

To be continued... possibly...

Yeah yeah yeah, they're very OOC, but hopefully that will change in the next chapter.

So what do you think? Is it a keeper? Should I keep going? :)

Please review, and thanks for reading! No flames please...
