When timmy`s parents realize vicky`s evilness FOR EVER?and when timmy and vicky are friends FOR EVER?

but i think if all of negatives of dimmsdale realize vicky`s evilness or timmy and vicky be friends in one episode in fairly oddparents,in next episode all of people will forget it or timmy and vicky will be enemies again;because the episodes of this cartoon don`t have any connection with together.what do you think?Am i right?
