the point is we are supposed to go with what is on screen, considering Ferb has a canonical crush on Vanessa, and has shown no interest in Gretchen, who never showed any interest in Ferb either by the way. Ryan you do make an interesting point Gretchen is considered Isabella's second in command so to speak, but then why does no one pair Buford up with Adyson or Katie for example, or Irving with Holly. No shown interest, no pairing simple as that
