What Might Have Been

What It Might Have Been is a song in the upcoming Phineas and Ferb episode, Act Your Age. It's performed by older Phineas Flynn and Isabella Garcia-Shapiro on how long it took Phineas to realise Isabella wanted to be his love.

Lyrics
Isabella: You didn't notice me and I couldn't go on like that. Now I finally decided that it's time to just let go. But it could have been so different, if just gave me a sign. You're very dear to me but everything just goes all wrong. I've dreamt all summer for our romance to begin. I hoped to forget you but there's again fog in my eyes. It could have been so different.

Phineas: So why were you always silent and didn't just say it out loud. You probably were hinted at it, but I was oh so blind and deaf. I was so busy all the time, making some weird stuff. But now I began to realize there was a million tiny hints. But now the summer's almost over and all my friends go and all my friends go on their ways. I was ready to fill every day but I guess it was for nought. It could have been so different.

Isabella: I dreamt to be your sweetheart.

Phineas: I wanted to be your friend. We would have been such a cute couple.

Isabella: And people would call us "Phinebella".

Phineas: I'd hold a door for you and open an umbrella.

Isabella: You'd caress my hair if I suddenly gotten ill.

Past Isabella: If she got ill.

Phineas and Isabella: I always wanted to go on a date with you. We'll always be good friends, but it could have been so different. It could have been so different. It could have been so different.
