When Jennifer is watching the video of Angelo Allieghieri, shots alternate between her sipping from a glass and swigging from a bottle of Jack Daniels.
When Jennifer says to Frankie that an Allieghieri will never bow down, Frankie says he wished he never said that to her. In fact, it was Angelo who told her that in his DVD message.
When Frankie and Jennifer talk in the kitchen, there's one candle on the table. Amy leaves and Frankie blows out a candle which was not on the table before.
