^I never said jessie&Luke wouldn't get together i said it would be funny if Disney did put them together because there's a 7 year age difference between Jessie and Luke. Where as ferb and vanessa are like a year off in age and no one knows the age difference between wendy&Dipper and whether or not the other 2 couples end up together depends on whether or not Disney decides to go in that direction with the other 2 couples and vanessa and ferb are only love interests and the epsoide act your age was a future epsoide where ferb and vanessa were seen together but we don't know if they were dating or not.we don't even know what direction Disney is leaning in.plus keep in mind disney shows only get 4 seasons and jessie is in its 4th and maybe last season so we might never know if putting jessie and luke together is the direction Disney was gonna go.phineas and ferb is on season 4 as well it has 2 more epsoides left maybe,the only couple we know for sure that end up together In the future are phineas&Isabella.gravity falls is on like season 2 but even then we still don't know which direction disney is going in for all 3 couples because of the stupid season 4 limit!
