I have not done a Fanfic in a long time…the last time I did one was for Salinger's Catcher in the Rye, and that was three months ago.

But now, I have taken upon a new sort of challenge: Putting myself in the eyes of the characters of the world of Phineas and Ferb. More specifically, I will write a story of the relationship between Phineas and Isabella.

I DO NOT OWN PHINEAS AND FERB, OR ANY CHARACTERS, TRADEMARKS, OR RELATED COPYRIGHTED MATERIAL.

Please, please review this chapter before the next one is uploaded; I would greatly appreciate it! Enjoy!

Prologue; The Mastermind Plan

The sky was starry and brilliant.

The rope ladders and the wardrobes were invisible, and the transparent windows were open slightly.

Isabella and Phineas wanted to see each other more often, and so they decided to sneak out at night when they were sure that their parents were not awake. They decided to sneak to each other's houses, more specifically, and to alternate who visited whom each day.

Tonight was the third night, and Phineas visited Isabella. Phineas would wear pajamas, and Isabella her white nightgown when they visited each other.

Accessing each other's rooms was an aspect of the scheme that Phineas addressed brilliantly. A week ago, recalling some properties of light and matter, he created some invisible paint with Ferb that they tested on the dining room table one day while Candace was left in charge of them. She believed that the table was actually missing and being used for one of the boys' inventions, but the boys washed the table secretly before their parents arrived, and the table had reappeared intact, much to Candace's amazement.

Phineas made some simple rope ladders in secret, covered the sides and rungs in invisible paint, and left them hanging from their bedroom windows. Each time either Phineas or Isabella arrived or left, the other would pull up the ladder and close the window, and put out the ladder again the next night.

Phineas had also recently built some six-foot-tall wooden wardrobes with the Fireside Girls a few days before that in helping them earn their Carpentry badges. Two wardrobes were used in the scheme, one in Isabella's room and one in that of Phineas. Both were covered in invisible paint and stashed away in a corner of the room. If one of them had to hide if a parent came in the room, the wardrobes would serve as a hiding spot until the parent left.

It was a perfect plan, the plan of a mastermind.
