This was my review for 14AmyChan's "Childhood Memories- Phineas' Home Video". She asked for the readers to make up their own ending for the story, so I did. This was my take on the ending, and she wanted me to upload it so that she could fav it. :)

Please note that I wasn't really trying to put too much detail into this, so it's really short and a bit rushed because I was indeed rushing.

Isabella was a fast cheetah sprinting down the seemingly everlasting stretch of sidewalk. She cursed herself for being so oblivious. She should have known Mrs. Flynn-Fletcher would pull something like this- she was good at setting these kinds of things up, and Phineas had taken her knack for planning.
Her feet fell into a rhythm of one in front of the other and she regulated her breathing so that she wouldn't run out of breath too quickly.
Questions began to go through her mind:
What was Phineas' reaction? Was he excited to see her? Or was he freaked out and hiding at home in the panic room?
Meanwhile, the aforementioned red-head was dashing in the same manner towards his companion. Though he didn't know that she was coming the same way. As he panted, he couldn't help but wonder if Isabella was going to be where he thought she was. He hoped that she was. Her three year-old self had said something that had dug a whole in the pit of his mind and buried itself back up, forever enclosing itself into his memory. He new that it had been quite a few years since then, but there was a possibility that she still felt the same way. He really hoped that she did, because now that he thought about it, Isabella was the most amazing, beautiful, smart, and sweetest person that he knew. He would absolutely not mind if she did like him in that way. But that was just his optimistic self talking.
The mad race to find the opposite significant other went on, and unbeknownst to the teenagers, they were now on the very same strip of sidewalk.
They hadn't realized each other sprinting in the same direction, not until about ten feet was left in between them. The sound of Isabella's name being called by the person she was looking for had caused her to stop and whip her head up.
"Phineas!" She exclaimed. She found herself to be paralyzed in her position.
Phineas' face was occupied by a smile that spread all the way up and made dimples on the corners of his cheeks.
He bounced a little on the balls of his feet, and then ran ahead and engulfed her in a big bear hug. She rang with laughter as she wrapped her legs around his waist and he spun her around until they got dizzy. She held tightly onto him and laughed into his shoulder, hugging him as he slowed to a stop.
Once she was able, she looked straight at him and into his eyes, and he only blinked in content.
"You know..." She said softly. "Deep down... We're still the little kids that we used to be."
Phineas opened his mouth to speak, but couldn't find the right words to say. She had taken them right out of his mouth.
Instead of speaking, he moved forward and touched her sweet little nose with the very tip of his. She giggled.
