"Izzy, the last field is about to fall down" Phineas told her. All this time they had been sitting like this enjoying the show together. Phineas felt so great but he couldn't understand why, he just let it go and enjoyed the moment he could spend with her.
"I know Phin" Isabella replied softly, her voice still shaking with excitement.
The last field was the largest field. It showed about every moment Phineas and Isabella had spent together on their trip around the world, ending with the famous hug on the island.
Isabella's eyes started to fill with tears again. "It's perfect Phin"
"Thanks" Phineas replied softly. Just then, the last stones were falling down and everybody cheered. Apart from a few flaws, about everything had fallen down!

"Mission accomplished" Ferb said.
"You said it, Ferb" Gretchen said.
Even Perry made his clattering noise to tell that he was happy to see one of his owners being so happy.

For Isabella, this day would be a day to remember. Even if Phineas still didn't know about her feelings, he sure had answered them!
Phineas stood up and reached for her hand to help her up as well. "So, what did you think!"
"This was just AMAZING. How did you even manage to place this many stones in just one day!" Isabella squealed.
"Well, we had to use a robot or 2 for that, but a big part was set up by hand." Phineas said.
The others just gestured to Isabella trying to tell her "He did most of it"
"Phineas this was just amazing! I … I'm just speechless" Isabella was happy as can be.
This made Phineas happy again. "Isabella Garcia-Shapiro, with this I want to let you know that I'm very grateful to have you as my friend and that you're always there, even when I lose it. You're the best friend anyone could ever wish for and I wouldn't want to miss you!"
Isabella was especially touched by what he had just said. Tears filled her eyes again and she could only bring out "Oh Phineas." She then hugged him tightly again. Phineas returned the hug.

"We'll eh... we'll go down then" Candace then said. "I mean, the structure is probably going to disappear soon and I don't want to be on it when that happens."
"Wha-? Oh right!" Stacy said.
"That includes fanboys, weirdo" Buford said, grabbing Irving by his pants and pulling him towards the elevator.
"Wait, I haven't gotten a good picture yeeeet" Irving screamed.
"Well done, chief!" the fireside girls said. Soon, everybody, even Ferb, were going down again.

Phineas and Isabella sat down again and  both could only smile broadly.
"Well Izzy, I hope the walk through the desert was worth it" Phineas grinned.
Isabella laughed "It was totally worth it."
"Well then" Phineas said and he took out the crystal from its pedestal. "You can have it."
"R-really?" Isabella's eyes widened and she was about to let some tears out yet again. She kept herself from doing so though. "Wow Phineas, in how many more ways are you going to thank me" she teased.
"Well I don't want to break it to you but that was about it" Phineas laughed.
"It's ok" Isabella laughed as well. "Thank you, Phineas Flynn. You don't know half how happy you made me today."
"I think I can make a guess" Phineas said, still grinning.
Just then, a loud bang was heard making them both stagger with shock.
"What was that?!" Isabella screamed. Phineas was at a loss
"You don't think Candace was right about that disappearing thing, right?" Phineas said with a worried look.
"No... wait look!" Isabella pointed at the sky.
A fireworks display had started. Everywhere in the sky, fireworks were bursting. From red to green, from blue to yellow. Phineas looked down to see Ferb standing with a device. When his gaze met Phineas's, he saluted him. Phineas smiled.
"Guess we can enjoy this night a little longer" Phineas said with a smile.
"Yes" Isabella smiled. Phineas lay down on the floor to enjoy the fireworks. Isabella lay down next to him, placed her head on his chest and looked up as well. Phineas was getting used to Isabella's behavior and didn't mind this. In fact, he found that he actually liked it. He placed a hand on her shoulder as a reply. Everything was perfect. It was like a dream but for real this time. She had pinched herself enough times to be sure of that. She wanted this moment to last. Just him and her laying down here watching fireworks. She enjoyed every moment of it and just before the fireworks were reaching its end, Isabella fell asleep. It had been a long day for her after all. Phineas smiled. He thought she looked so cute and peaceful right now. He did feel a little sleepy himself. He had certainly enjoyed himself with her and hoped that it would stay that way for many years to follow. He wouldn't even mind if they would stay here, laying like this for a while. He thought back of everything that had happened today, especially this last part and slowly, he fell asleep as well.

When Phineas woke up again, he looked around with a confused look in his eyes. He was back in his own room again and the sun shone bright. He looked at the clock and saw that he had only just beaten it. He looked around again. He could see Ferb and Perry still asleep. Where was Isabella? What had happened to the plateau? Just then, the alarm sounded and Ferb woke up.
"Ferb, good morning... uh, what happened last night?" Phineas asked confused.
Ferb thought it was an amusing question. Normally, it would have been asked by someone with a hang-over, discovering a wedding-ring on his finger or something like that. "You and Isabella fell asleep and we sort of had to pull you apart as you were tangled up with each other quite tightly. She's at home and is about to wake up in a similar fashion to how you did just now" Ferb answered. He enjoyed teasing his brother and now, he had found a reason: Isabella. Maybe with a lot of teasing on his behalf, Phineas would notice one day.
"Wow, guess we were really tired then" Phineas grinned and placed an arm behind his head. He himself couldn't quite place the feelings he felt but it sure felt good.
Ferb just shrugged. He could have sworn Phineas was blushing a bit when Ferb said what he said but he didn't say anything of course.
"Last night was great! Thanks for the fireworks, that was a nice touch."
"You're welcome, brother."
"Oh, by the way Ferb, you never told me why Vanessa wanted to speak with you. Isabella didn't give me an answer. Well, I didn't expect her to but still..." Phineas asked.
Ferb rolled his eyes and thought "still as oblivious as ever." He then said "If I told you now, it would ruin a big secret." He was referring to Isabella's big crush.
"Hmm..." Phineas still didn't know what he was talking about but decided he'd find out one day or another. It wasn't top priority right now, was it? "And the plateau? What happened to that?"
"Well for some reason it was destroyed by a gigantic marble but I do not know what happened to the remains."
"Hmm, a gigantic marble huh?... Ferb, I know what we're gonna do today!" Phineas exclaimed. "We're going to build the biggest marble-playground in the world! We might even be able to cover the entire tri-state area with this!"

Somewhere, a certain evil doctor stirred in his sleep.

Ferb rolled his eyes but agreed all the same as he always did.
"Come on, let's go!" Phineas exclaimed and soon, they were going to the backyard again. His mind was set on the new idea but part of him still reminded him of the great night he'd had last night. He just couldn't wait to see Isabella again. He still didn't know why but after last night, he just wanted to be with her again. He wanted to hear her voice again.

Just then, Isabella walked into the backyard. She had heard about what had happened last night from her mother who had heard everything from the fireside girls. She saw Phineas and her heart raced again. She walked towards him.
"What'cha doin'?"
