Disclaimer: I do NOT own Phineas and Ferb.

62 years earlier (2000)

Linda Flynn was expecting her newborn son. She had already had a daughter, Candace, with her loving husband. Although, he wasn't really that loving. They had been fighting so much. Arguing, not that type of fighting. She wanted to work it out, but he wasn't so sure. Unknown to her, he had been cheating. He was getting ready to leave. In fact, he wouldn't even have the opportunity to see his son. When her son was born, he had some problems. He was immediately taken away. She didn't even get to see him. A few hours later, he was back. He was beautiful. He had a tinge of bright red hair, and a triangle-shaped head. That was a bit weird, but he was her's. She finally had a son, along with a daughter. He had bright blue eyes, and was absolutely precious. Little did she know what was to come. Little did she know…

13 years later (2013)

Phineas's POV

My name is Phineas Flynn. I am 13 years old now. I have a 17 year old sister, Candace and a 13 year old stepbrother, Ferb. For the past 10 years I have been best friends with Ferb and my neighbor, Isabella Garcia-Shapiro. Isabella. So nice. And cute. Yep. I admit it, loud and proud. I like her. A lot. I've never told anyone, not even Ferb. I think I should though. Just to change the subject, I feel very… different. From everyone. I honestly has no idea why. I've never felt in place. Not with my friends. Not in school. Not even at home. I just feel so different. It feels like I don't belong here. It's as if I'm from another planet. I just feel so… wrong. I suppose that's normal though. I've heard of other people sounding weird like this before. So that's what I did, I told myself it was normal to sound like this. I did for almost that whole summer. Until that one unfaithful day.

2 months later (end of summer)

"Phineas, can you come here please?" my mom asked, oddly enough, she sounded worried and… nice, too nice.
I ran over to the living room, where she currently was, good and ready to hear her out. To my surprise, dad was there too.
"Phineas dear, we have something to tell you." my mom said.
My expression just fell, what's going on? "Wha- What is it?" I asked, hoping I didn't look too worried.
"Phineas, the hospital called today with some- some news." my dad said, finally speaking up.
"Wha-?" I began, but was cut off.
"Phineas, they said that you- you aren't our blood child. They said the baby I gave birth to died. Long story-short, there was a mix-up, no one was able to find your actual parents, and they gave us you." my mom choked out. I'm pretty sure there's tears swimming in her eyes, waiting just to flow out.
I felt my heart cracking slightly. I felt like crying- not that I would. I was so shocked. I just nodded and let out a slight "o-oh". Then I ran up to my room and locked the door. Sorry Ferb, I'll be in here a while. I sank into my bed. First I continually thought about how I'm not related to my family. So now I have a stepmom, stepdad, stepsister, and stepbrother. In other words the only blood relation is between my mom and Candace. Then it hit me. Why did my actual parents abandon me? Why? Was I not good enough for them? Did they want a girl? Was I too ugly? Too unsatisfactory? Why? I couldn't believe it. There was one thing that was however clear to me. I had to, and would, find out who my actual parents are. I wonder if I have any siblings. Ugh. I was about ready to unlock the door, and possibly go back outside with Ferb, but the next thing I knew, it was 7 in the morning.

Ferb's POV

Poor guy. Mom and dad just told me last night. I heard a door slam, so I came in. Candace must of heard too, because she left her room. Once we were down, we immediately saw mom crying, and dad looking crestfallen. It was depressing. Based on their expressions, and the door slamming, we both instantly thought Phineas uncharacteristically did something bad. When they explained, I felt extremely guilty. I can't believe it. I went upstairs to talk to him, as much as I hate doing so, but to my dismay, the door was locked. I checked back later, and it was still locked. I guess I'll be on the couch tonight. It's okay. I just hope he feels better tomorrow.

Isabella's POV

I went to bed, thinking of Phineas of course. Something felt wrong. As if something bad happened. This is another reason I feel like we're made for each other. It's like I'm feeling what he is. Yes, I have had feeling for him for 10 whole years. I can't wait for tomorrow. Tomorrow, when I get to see him again. That's something to look forward to. I continue to think, until I slowly drifted into a deep sleep.
