"Phineas its me! Isabella! I've lived across the street from you since before Ferb became your step brother!" Phineas was the one confused now.
"Who's Ferb?" Isabella out of pure shock was able to get a finger pointed in the direction of Ferb "The British kid?" Phineas asked pointing a finger over his shoulder. He quickly put things together. "I hit my head pretty hard didn't I." It wasn't a question. He looked back to Isabella. "So, bella? does that make you my girlfriend?" Isabella would have passed out if this was a good time for it.
"Umm no we're.. just friends." There was pretty evident disappointment in her voice. Even Phineas had to comment on it.
"You don't seem too happy about us being just friends." Isabella was in shock but Ferb decided to save the day
"Phineas I believe it is time for you to get your concussion looked at at a hospital." They called their mom who immediately came home to drive them to the hospital.
"Phineas I told you and I told you not to climb that tree but you did it anyways. Its not like I didn't remind you it was dangerous." Phineas's mom said driving like crazy to the hospital. Phineas, still being an optimist replied smiling.
"Sorry, I forgot"
The doctor was an old man with gray hair and a white mustache. His age left his back curved but his stature demanded respect despite it.
"Okay Mr. Flynn there really isn't much to say. Retrograde amnesia isn't rare with head trauma. Generally the first things people forget are facts about themselves but its not unheard of it being the other way around. From what these people have told me your personality seems mostly unaffected which is a good sign. The good news is the memory loss generally wears off within a couple days or in more severe cases a couple weeks."
"What's the bad news then?" Phineas asked the doctor, listening intently to every word
"Well its also not unheard of that, if its severe enough, for the memories not to return. It appears however your ability to store short term memories is working. By tomorrow we'll know if you ability to convert them to long term memories is intact. Beyond that its up to chance really on how and when your memories come back."
"Is there anything in specific you would recommend?"
"Just do what you usually do with who you usually do it with. Maybe it'll trigger something. Whether it does or not I don't know but it'll sure be a new experience for your friends to get to know you again and you them." The doctor was clearly beginning to catch Phineas's optimism.
"Hey mom, since he wants me to do what I usually do does that mean I should climb the tree?" Isabella, Ferb, and Linda all looked at him and yelled "No!" Lawrence just kept driving with a smile on his face. He was still the same person, that was for certain.
"Your saying I took part in building these things." Phineas's eyes were filled with the same amazement they had for almost everything he saw. He was being shown some old photos of his inventions.
"You designed most of them." Ferb said "But this photo is the cou de crayon."
"Pencil neck?" Phineas asked confused. He looked down to see Candace on the runway. He smiled a bit at the parts of his life
"So got any ideas for things to build Phineas?" Isabella asked enjoying the moments in Phineas's life as much as he was. Phineas put a hand to his chin.
"Well something to bring memories back comes to mind, but I'm not really feeling a design come to me. Maybe tomorrow I'll come up with something. We could always come back to something for my memories later."
"Well I'm gonna go inside and make sure nobody has plans to come over and enjoy what you built tomorrow. Except for Buford and Baljeet. That will be a fun second meeting." Ferb left and Phineas opened his mouth to ask a question but Isabella beat him too it.
"They're a bully and his nerd, except they're best friends." Phineas closed his mouth. Then he decided to start a conversation
"So Isabella, tell me about yourself." Isabella looked at him questioningly and then decided why not and gave him a synopsis of her life and when she met him etc. Phineas was listening intently when Isabella stopped herself
"I'm sorry," she said blushing, "I'm here going on about myself and you don't even know who I am or who you are. Plus you have a head injury and here I am feeding you information." Phineas sat up and quickly summerised her summery of her life to prove he was listening. "Even for someone with a good memory that was pretty impressive." Isabella said, impressed with the person who she had seen break laws of nature like they weren't there.
"Well your worth the extra effort." Isabella blushed so Phineas decided to continue something before his suspicions about the amnesia were confirmed by a doctor. "So Isabella, I couldn't help but notice how much of my life you were in and I have to ask something."
"What is it?" Isabella was expecting something about how they met or something so she was surprised when he asked
"Do you like me?" Isabella basically passed out without going unconscious. Her face fell blank and she sat in a way that showed utter concentration. Phineas decided to add a follow up question. "Did I really never notice that?" Isabella still shocked was able to form a thought into a sentence.
"Well no you didn't. Not at all really. It was almost impressive to a certain degree."
"I seemed to have done everything above and beyond. Hopefully I could at least get that back for the good things." Isabella was shocked by the sudden question, but now that she thought about it the reason he noticed was because of something that happened suddenly.
"Well I'm still a little shocked by the question. I'm forgetting that your the same person with a different thought process due to your different, or better yet lack of experiences."
"Actually I can almost feel that my thoughts are the same. Even before I asked that my mind was dismissing that my best friend since I was 3 liked me. Then I had that moment of 'she would have told me' which I then realized you could have." He rolled his eyes at himself. "But you know, without the memories with you I guess it was easier to notice. Before I probably dismissed it as 'Isabella's being nice as always'"
"Is that whats been going on in your mind?" Isabella shook her head with a smile then tried to make an angry face at Phineas. "That would have been helpful to know back when you remembered me."
"My bad, I won't let it happen again." Phineas said first with his arms defensively up then with a hand crossing his heart.
"Soooo.. now what?" Isabella asked as the awkwardness became more and more evident in the air between the two.
"Well.. Your definitely the cutest girl I've ever seen, and that's not just because the other two were my mom and sister. But I have a feeling I had a scientific mind and treated everything experimentally, and while it would be fun for my memories of you to hit me with us already dating, it would probably be easier for me to have known you for more than 24 hours before I officially ask you out." Isabella let out something she had been holding in since this conversation started, she passed out.
Isabella awoke to find some water on her face and Phineas standing over her now looking relieved.
"Are you sure I was oblivious before? I compliment you and you completely lose focus for a couple of seconds. And you appear to have been here every day for years. I should have picked up on something."
"You had your moments. And I had some help to keep it concealed."
"From who?" Isabella smiled a bit
"Pretty much everyone actually." Phineas smiled back as he helped her up and she walked home.
