I too agree things are wrapping up "rather quickly" as they say! I think Cook (mrs. ?) will be leaning toward Mr. Mason- daisy's father in law; daisy and the farm helper/house boy; barrow ?
i found one line sort of strange in this last episode.....when mrs Hughes was talking to Cook about what Carson said to her about her cooking " not being like his mother's". My first thought was...he was employed in service at the house since a young man, eating whatever was cooked there...why suddenly recalling and expecting food like mama made!
oh well, just an observation.....
