I don't know about this guys, but...
You know that episode where Isabella, Candace and the other go back in time and they see their future mom, children, whatever?
Well, it kind of bugged me when, one of Candace's kids said , "Hey, is that Aunt Isabella?" or something like that, Isabella said that Phineas and her got married after all but then Candace ruined the moment that maybe Ferb married her instead of Phineas. Now that bugged me a lot.
Now here's my question,
WHAT IF ISABELLA AND FERB WERE THE ONE WHO GOT MARRIED?
