Plot hole: At the end of this episode, the lady who was on the TV show with Blanche and Dorothy as "partners", shows up to ask Dorothy out because her and Blanche broke up. She says "I heard about you and Blanche". How could she have heard it? They just did it at the house.
Plot hole: Dorothy's son Michael is twenty-two years old in season three. When Sophia and Dorothy reminisce Brooklyn, NY, 1954, Dorothy asks Sophia to babysit her children, one of whom is Michael. Sophia refuses, so Dorothy says "I'll just leave them with Stan's mother." They talk about Michael screaming when Stan's mother was watching over them. If Michael was a baby in the fifties, he should be in his thirties in season three.
