@Lala I can see why are you having that theory, but I'm doubting it. That's why: Well, Isabella's mum name is "Garcia-Shapiro", Garcia being a Spanish/Mexican name and "Shapiro" a Jewish name. Also, Major Monogram refers to his wife as "Mrs. Monogram" and he married her like 12 years ago(That's from that Christmas Letter on Canon). Eh, that can match with Isabella's age, but it still seems a little impossible. About the physical appearance, Isabella looks like her mother and I don't see similarities to Major Monogram. And there's the thing that Fossy said. Oh, and their personalities don't match very much.

Also, Phineas' voice in Hindi sounds awfully familiar.
