Summary:

Isabella is injured one day while helping Phineas and Ferb construct an invention. After awaking in the hospital, she has an odd case of amnesia, where she remembers who she is and her whole life, but doesn't remember Phineas and Ferb. Phineas is devastated, while Ferb tries to reconnect with her and cure her amnesia… PxIxF. Rated for thematic events, minor use of vulgar language, and though-bubble violence in the case of psychiatric breakdowns. Please R&R.

Prologue- Not As Planned

Even someone like me should have known that sooner or later, things like this would be inevitable to avoid. I mean, I had never intended on even realizing this, but I knew somewhere, deep down, that our friendship…wasn't quite the way it should be…

I should have known that I would feel this way. I should have been able to prevent all of this to happen. But…I wasn't fast enough….I wasn't good enough. I'm still not good enough....

But I digress, so maybe I should start from the beginning?

Well, it all began with my mom and my dad—no wait, that's too far.

Okay. I've been friends with Isabella for as long as I can remember…

She was always reluctant to talk to me as we got older, but then I got a new dad, and an awesome stepbrother, Ferb! And then, suddenly, Isabella started to come up and talk to me like she used to back in kindergarten. It was a little unexpected, but helped out more than I ever could have imagined. She was such an…activist. She loved to stand out and prove that girls can do whatever they wanted. She helped me out with anything and everything. And she was such a great leader and an amazing role model to all her friends. And she was so popular and adorable. She was so cute and kind…with such a perfect personality.

And I ruined all of it….

Basically, we were best friends. And you have no idea how close we really were. We talked to each other all the time. We helped each other out if the other ever needed anything. We'd both even taken care of each other when one of us was sick.

Well, one day…during July…

"Hey, Ferb! I know what we're gonna do today!" Phineas shouted, with a gleam in his eye. He ran towards his brother, and then spun around real fast.

"Let's do some minor applied physics, and just find a very simple alternative to gasoline, to use in cars! OH! And we can use Mom's station wagon, too!" Phineas declared. Ferb stood there, silently.

"Uhh…I guess we wouldn't really be able to start the car ourselves, would we?" Phineas thought for a moment, and Ferb shook his head. Suddenly, Phineas lightened up, now declaring a brand new idea.

"We could always make a really small carnival, like, a mobile one! And travel around the town in it, entertaining kids!"

Ferb nodded, and Phineas high-fived him.

"Yes! Let's do it!"

And just then, there was a small second of silence, and then a high-pitched voice came from nowhere, asking,
"Whatcha' doin', Phineas?"

Phineas turned around, already smiling, to greet his best friend, Isabella. She was dressed as usual, in her white tee, pink dress, pink belt, over-the-knee socks, and pink shoes. She smiled, and Phineas started to explain to her what he had just decided to do for that day.

"Oh, that sounds so cool, Phineas! Maybe you could even visit some kids at the hospital downtown?" Isabella was in pure admiration of Phineas' amazingly kind idea.

Phineas and Ferb both agreed with her, and Ferb instantly began to draw out the blueprints for their Mobile Carnival.

Isabella continued walking with Phineas, into his house, and into the kitchen. He took out three glasses from the cupboard, not having to reach up on his tip-toes anymore. Isabella smiled as he began to pour iced tea into all the glasses. He went to the fridge and found a lemon. Bringing it back with him, he started talking to Isabella.

"So, I heard you talking to Ferb yesterday. You guys were sure in-depth in that conversation."

Isabella's eyes went wide. Did she detect a hint of…jealousy?

"I mean, it's none of my business…but Ferb's not one to talk to many people…at least not out loud," Phineas continued, getting out a knife, and butting the lemon into thick slices. "I can see why he loves it so much, though. You're such a great person to talk to, Izzy. I'm glad Ferb is finally realizing it. I mean, I'm sure that after a while, he'll feel the same way I do—" He paused. He put the knife in the sink and put a half lemon on each glass.

"—I know that I wouldn't be able to go more than a day without talking to you…that's for sure." He stopped, and handed her a glass, putting a pink straw inside. She grinned brightly.

"And that—" He continued. She paused, confused. "Hmm?" she asked. Phineas laughed,

"Your smile. Never a day will I go without it."

Isabella felt her face heating up more and more as Phineas continued. Eventually, they both went outside to find Ferb already collecting supplies. Phineas handed his brother the last glass, and Ferb took it, chugged it down (lemon and all), and then gave the glass back.

Isabella and Phineas started laughing as Ferb burped loudly, and then excused himself. They continued to collect miscellaneous supplies, and eventually started to build their masterpiece.

Starting from the bottom, they made a vehicular structure, so that they could easily drive it around. On top of that, they made a ground base, so that the performers would have at least SOME solid ground to stand on. And then they added walls, and began to fill the big "box-on-wheels" with toys and candy and other fun things.

Phineas climbed inside, and was screwing in a side wall's hinge. Isabella stood right next to that wall, holding it up with a rope that was safely tied all around the box. Phineas installed the second hinge, and then told Isabella to let go. She did so, and stood back to look at the magnificent invention.

But, just then, the wall suddenly came crashing down, right for her. She didn't even think to react in enough time, and was smacked in the head, and pulled under the wall's heavy weight.

Phineas' eyes went wide, and he jumped out, and immediately started to try lifting the wall. It was too heavy for him, so he called for help.

"Ferb?! Candice?! Hello? Anyone?!" He tried harder still, and it moved just a little. He gave it everything he had, and lifted it up enough to keep it just above his head. Suddenly, Ferb ran outside, and saw what was happening. He dashed across the yard, scooping up the unconscious Isabella, and dashing back across the yard again. Phineas' arms nearly gave out as he escaped from under the massive weight of the wall. But he wasn't a tad bit concerned with his own well-being.

"Izzy!" Phineas ran as fast as he could to Isabella's side. He fell to his knees, his hands trembling.

"How could I have let this happen….? I'm never going to forgive myself for this…!"

Ferb held Isabella's sleeping face up with his palm, and watched as a trickle of blood seeped through her scalp, through her raven-black hair, over her relaxed cheeks, and under her chin.

"I'll get Candice. She'll get us to the hospital." Ferb stood, and Phineas rushed to hold Isabella in his arms. He felt like crying, but couldn't find the strength to let himself do it. He couldn't cry.

Not in front of her…even now.

I must be strong.
