Actually, I believe the reason we (the Fertchen shippers) ship Ferb/Gretchen is because we believed Ferb needed a girlfriend who wasn't seven years older than him. Besides, I've seen quite a few couples who hooked up without any onscreen chemistry, so it wouldn't surprise me if Ferb ended up with Gretchen.
