Oooooh. My goodness. That explains so much. Thank you for sharing! Ha, and all this time, we believed Alt. Phineas would hold some sort of penchant for Alt. Isabella. Hate to advocate this more than need be, but again - Swampy responded with "wait for the movie" when inquired about Phineas and Isabella's relationship. Presuming the alternate counterparts will fail to embody any 'Phinbella'... ; )

Regardless. What - particularly - made Isabella's affection for Ferb evident?
