The Father Christmas Suit - S2-E11
Revealing mistake: There are many Christmas cards scattered around the house but you can see in a lot of the shots that they have nothing written in them.
Suggested correction: It's implied she sent the cards to herself.
Trivia: Hyacinth somehow manages to open a pull door by pushing. When Hyacinth is about to walk into the store with Councillor Mrs. Nugent (24mins approx), they walk to the door and Hyacinth pushes the door, which is labeled "Pull."
Suggested correction: This belongs under mistakes, not trivia.
Continuity mistake: At the end of the scene where Hyacinth is fighting Major's advances in the greenhouse, she's seen holding fresh flowers. However, just as she's running down the stairs, the flowers are wilted and broken.
Suggested correction: This is not a mistake; it is intentional that the flowers have been damaged as Hyacinth tries to evade the Major.
