When Dorothy is making the recording about Sophia, she mentions that Sophia refused to be "thought of as property and demanding instead to marry a man she loved." Sophia says that she had her marriage to Guido annulled and then sailed to America. But at other times in the series, Sophia mentions that she didn't choose to marry Sal. And, she was already married to Sal when she came to America.
Dorothy states in this episode that they don't have a yard flamingo but in a season one episode ("The Way We Met"), she says that they do.
When the girls are going to vote, Sophia first picks up a pen to deliver her joke. The very next shot, she's holding a pencil.
