As it turned out, Aunt Rosa figured out that the two were now dating. She was at first surprised by the news, since Phineas had said that the moment of truth would be Saturday. Nonetheless, she smiled and wished them good luck.
She also expressed her confidence in the strength of Phineas' and Isabella's relationship, reiterating, "You both have a good solid foundation of years of friendship, and show much more care than most married couples. You know each other very well. Now that you both are dating, you are developing a new form of connection. But I'm confident that you will form a lasting relationship. I'm sure of it."
When they arrived at Uncle Juan's house, Phineas and Isabella retired to their guest room to arrange their clothes. When they came out, Rosa was standing in the living room. She said in a slightly stern voice, "Now that you guys are dating, I think we're going to have to change the sleeping arrangements around here."
Phineas and Isabella knew what she meant, and winced at the prospect. It wasn't because they were planning anything. Rather, it was because they had already gotten used to sleeping together over the course of the three-day stay in the grandparents' house. It was a rather moot point, since they inevitably would sleep in their own houses back at Danville. But the idea of being in separate rooms bothered them a little.
Rosa must have noticed the concerned look on their faces, because she laughed and said, "Just kidding, guys. I know you wouldn't do anything questionable. But it goes without saying that I won't put up with any nonsense in this house."
The couple nodded in agreement and retired to the guest room. They talked for hours, just remembering adventures and experiences they had shared over the years. Phineas brought up, "Remember when we first met?"
"Yeah, it was in first grade," Isabella replied. "Me and my mom had just moved in across the street and your mom introduced me to you and Ferb. I remember you helping me unpack my boxes. You even helped me arrange my room. We ended up talking for hours."
He chuckled, "I don't even remember what we were talking about."
"I don't remember either, Phin. But you were quite social with me, considering it was the first time we met. It was then that the feeling hit me." She sighed dreamily, "I was a small girl that dreamed of being this sort of princess that would meet a prince and live happily ever after. I imagined my prince to be sweet, charming, and charismatic. Somebody I felt totally comfortable and in love with."
She smiled, "I remember thinking that you were the realization of that dream. You were everything that I was looking for. We were seven, Phineas. Doesn't it seem like such an incredible story? Who knew that all these years later, we would end up dating?"
"Indeed, it seems like such a dream. But I'm glad that the dream is a reality now. How serendipitous, don't you think?"
"Yes, definitely serendipitous. I love you so much, Phineas. You are my knight in shining armor."
He knelt in front of her and held her hand in the manner of the cheesiest fairy tale prince. "Don't get me wrong. I'm definitely no knight in shining armor, or a Prince Charming. I still have my flaws and quirks, and I acknowledge that I might be hard to deal with sometimes."
Isabella chuckled, "I know that. You are quite stubborn and hard-headed sometimes. We've been best friends for a long time - I know you like a book. Needless to say, I'm aware of your flaws and quirks. If anything, they make me love you even more. I don't see your quirks as flaws. To me, they're like the pinches of reality that tell me that I'm not dreaming."
He grinned, "That's a cute way of putting it, Izzy."
"It's true though. And as for your quirks - your obsession for engineering and building things, your perfectionism - I find them quite attractive." Phineas couldn't help himself, and laughed out loud. She scoffed playfully, "What? I'm turned on by a smart guy that's good at what he does."
"Oh...you know there are other guys out there that are smarter and more perfectionist than me, right?"
"Yeah, but you're the most handsome and charismatic of them all. My eyes are firmly set on you, Phin. I only love you."
He got up from his kneeling position and sat next to her on her bed. He smiled and replied, "Fair enough." Then, he pulled her in for a kiss. He held her in his arms for an eternity of time that seemed to stand still. Both Phineas and Isabella didn't want this moment of magic and emotion to end.
They whispered sweet nothings in each other's ears and talked some more about their optimism for the future. They needn't worry about setting down terms and conditions for the relationship. Each knew exactly what the other expected of them, and were willing to please. Before long, they realized how late it was.
"Oh crap, it's eleven already," Phineas said. "We should really get to sleep."
Isabella smiled and replied, "Okay."
They changed into their sleepwear, and Phineas gave his girlfriend a goodnight hug, paired with a goodnight kiss. He held her close for a long time, before going back to his bed and turning off the lights.
"Goodnight, Izzy."
"Goodnight, Phin."
There was a moment of silence. Phineas smiled in the dark, "Guess what?"
"Hmm?"
"I love you, so much."
She giggled, "I love you too."
Soon, they fell asleep, with nothing but happiness and optimism. There were no nightmares, worries, or heavy thoughts. Now that they had each other, there was nothing left but pure bliss.
Sorry, but I won't update for two days or so. School, homework, and random responsibilities are really kicking my butt right now. But I'll update by the weekend, I'm sure of it. The story should be complete with an epilogue of sorts by the middle of the month. From there I don't really know what I'll write. Maybe you guys can give me some ideas :)
