Background Info: This story is set the summer before the start of freshman year in high school for Phineas, Ferb, Isabella, and the rest of the group. I don't know what grade they're in during the show, so I'm going off of my year as a freshman and saying they're 14-15 years old. Phineas & Isabella would both be 15 by the time school starts as their birthdays are over the summer.

I have another story going that isn't finished at the moment but will be within a week or so but this popped into my mind a few days ago and really wanted to get started while it was fresh in my head.

So, Phineas & Isabella are 15, the rest of the gang is 14.

Enjoy

A somber, puffy cheeked Isabella Garcia-Shapiro stared out of the passenger window as her mom drove them back home from the dentist's.

Unbelievable, I always take good care of my teeth. How in the world do I end up getting a cavity?

She sighed and reached up to open her sun visor. Viewing her reflection in the visor's mirror, she attempted to feign a smile but no luck. The anesthesia the dentist had given her prior to her procedure had left her mouth and cheeks numb; her normal, bubbly demeanor would not be visible today sadly. She pushed the visor back up to its closed position and sighed once again.

Coming to a stop at a red light, her mother turned to her.

"Don't be so hard on yourself Isa, these things happen sometimes. Remember when you had to get your tonsils taken out? That was out of the blue wasn't it?

"I guess." Isabella shrugged. Sure, her mother was right. Maybe she hadn't been taking as good of care brushing her teeth as she thought she was. To be honest, the cavity wasn't that big of a deal to her. She would learn it, she knew she would. She would make sure it was her first and last cavity. She was more bummed about her appearance.

"I look like a chipmunk." Isabella said with a roll of her eyes.

Her mother laughed as the light turned green.

"You're over exaggerating Isa; the anesthesia will wear off soon"

Yeah, soon...

Isabella focused onto the time the radio displayed.

3:24 p.m.

"The dentist said the anesthesia wears off in about 2 hours and that when it does to wait another 2 hours, just to be sure the filling is hardened."

"It's a good thing you ate lunch early today. Don't worry; I'll start making dinner a bit later so we can eat together."

Isabella smiled, or at least felt like she was. Her numbed mouth failed to produce the smile she felt she was making.

"Thanks mom." Isabella looked out of her window again.

By the time this anesthesia wears off it'll be too late to head over to Phineas'. They're probably wrapping up their big project anyway.

As they turned onto Maple Drive, unaware to them both, a red laser burst flew by overhead towards a certain duo's back yard. Some say, if you listened closely enough, you could've heard a Drusselsteinian accent cursing a monotreme far off in the distance.

As Mrs. Garcia-Shapiro turned into their driveway, Isabella could see Phineas and Ferb exiting their backyard and taking a seat in the front yard. Isabella groaned.

It's bad enough I look like this, now I have to have Phineas see me like this too?

As Isabella and her mother made their way from the car to their front door, Isabella saw that they weren't aware of her. The two brothers appeared to be talking, presumably recapping yet another marvelous day of summer.

Thank goodness they're so carried away in their discussion they haven't noticed us. Isabella would rue thinking that a second later.

"Look Isa, it's your friends. Phineas! Ferb! Hello!" Her mother boisterously waved at the two boys.

Oh no. Isabella went cold.

"Oh, hi Mrs. Garcia-Shapiro! Hey Isabella! We didn't see you guys pull in!" Phineas shouted across the street as he rose to his feet.

"Maaa." Isabella whined. Grabbing the keys to the house out of her mother's grasp, she dashed to the door and dove inside.

"Oy vey, was it something I said?"

"Hey Mrs. Garcia-Shapiro, what's up with Isabella?" Phineas, who had crossed the street along with Ferb, asked.

"My oh my you two have grown," Isabella's mother remarked for the umpteenth time this summer, "She's a little down after coming back from the dentist's."

Phineas' face radiated a look of concern.

"Don't worry Phineas; I assure you she's fine."

Oh yeah, I'm fine Phineas. Just don't look at me or talk to me because I'll probably end up drooling considering how numb my mouth is. That is NOT attractive. Isabella, who was leaning on her front door listening in on the conversation outside, thought to herself; she crossed her arms and pouted.

"Are you sure? We could make her something to make feel better?" Phineas insisted. Mrs. Garcia-Shapiro merely shook her head.

"She's fine boys. Speaking of which, what did you two do today?"

"We made a gyroscopic Ferris wheel! A normal Ferris wheel is fun and all, but why not be able rotate any direction you want?"

"Ah sounds wonderful!" Mrs. Garcia-Shapiro exclaimed. The imagination of these two, it amazes me. She thought to herself.

"We were hoping it would stay long enough for Isabella to see but when we came back outside after a snack it was gone."

Ferb nodded.

A chitter came from beneath them all.

"There you are Perry." Ferb picked up Perry and patted his head.

Linda Flynn-Fletcher pulled up across the street and waved to the three.

"Hey boys! How're you doing Viv!?" She called out.

"Hi mom!" Phineas said as he and Ferb waved to their mother.

"Doing well Linda! Your boys were just telling me about their day. Gyroscopic Ferris wheel today." She told Linda with a knowing look. Linda nodded as she exited her car.

"Ferris wheel huh boys?" She humored them.

"A gyroscopic one!" Phineas corrected her as the brothers made their way across the street. "Bye Mrs. Garcia-Shapiro! Say hi to Isabella for me!"

Isabella almost swooned.

"Oh and for Ferb too!" Phineas requested.

Isabella recuperated from her near swoon and groaned. C'mon Phineas.

The brothers had caught up with their mother, who was stopped at their mailbox.

"Hey Viv! High school schedules are in, make sure Isabella gets hers!" Linda said as she waved goodbye.

"Will do!" Vivian waved back as the door behind her opened. An arm extended from behind the door, opened the mailbox mounted on the side of the home and removed the contents within.

Vivian opened the mailbox to see it was empty and when she turned around to tell Linda she saw that they had already gone inside. She shrugged. Maybe tomorrow.

She went inside to see Isabella's face buried into her schedule and texting away.

After eating dinner almost 2 hours later than they usually do, Isabella went up to her room and lay on her bed. She rubbed her cheeks, relieved that the anesthesia had worn off.

I look normal now, she thought as she sat up and looked at herself in her mirror. Her eyes shifted to the envelope lying on her desk. She grabbed the envelope and returned to her bed where she opened the paper inside.

She had already talked to her Fireside Girls troop to see what classes they had. Thankfully she would see them all at some point during the school day. However, none of them had lunch 2. They were all given lunch 3; as the last lunch period of the day, it's usually an all-freshman lunch.

She got up and looked out of her window at the house across from hers.

I wonder what Phineas' schedule looks like.

Looking back at the schedule lying on her bed, she took a deep breath and took a picture of her schedule with her phone. Marking Phineas as the recipient of the message, she hit send.

Phineas was lying on his bed watching Ferb draw away at his drafting table when his phone buzzed. Looking at the phone, he furrowed his brow.

Isabella?

He opened her message.

Hey Phineas! Do we have any classes together? :)

I sure hope so! Phineas thought to himself as he retrieved his schedule off of his desk.

He opened Isabella's attached picture and compared her schedule to his.

"Oh…" He said dejectedly after a few moments of reviewing the two schedules.

Ferb stopped his drawing and put his pencil down before turning towards Phineas, eyebrow raised in a perplexed manner.

Phineas noticed this. Looking up, he shook his head.

"It's nothing Ferb." Phineas insisted as he sent a reply to Isabella.

"So, what do you have planned for tomorrow man?"

Ferb held up the schematics to tomorrow's big invention.

"Freeze Tag Zorbing!? Awesome!"

Isabella had been eagerly waiting for her phone to buzz. When it did, she snatched at it and took another deep breath before reading Phineas' text.

We don't have any classes together :( but I'm in lunch 2 with you!

Isabella blankly stared at her phone for a while before typing a quick reply and then closing it.

Great! See you in the cafeteria on the first day then

Not great. She sighed and put her phone on her night table before falling down, back first, onto her bed.

We have lunch together. My first year of high school and the one place I'll ever get to see Phineas is in the cafeteria.

It was better than nothing she supposed, but she imagined her first year of high school would include Phineas in some classes. She imagined them being partners for science lab, sitting next to him in math, talking about English books with him, doing homework with him after school. But no, she wouldn't get to experience any of that her first year.

Lunch…

Isabella took her pillow, gently placed it on her faced and groaned.
