The Perfect Ending
Ok this would have (probably) never happened if the show had decided to do a proper ending but for a long time I had been thinking that they could have done an outrageous ending for the final episode and here were my thoughts.
Daisy finally leaves Onslow because she realizes that she can't change him.
Hyacinth discover that Richard has been having an affair with Rose.
Elizabeth finally has the courage to say no to Hyacinth and tells her what she thinks of her. And in seeing this, Emmett and the Vicar do the same.
And a shocked Hyacinth's final words before the show closes would be "If my Sheridan were here he'd be appalled"
