Plot hole: In the scene where the FBI plays the tape to Tony and reveals the conspiracy between his mother and Junior, it is stated that the bugs were placed at Green Grove. However, the second conversation played in the sequence actually took place outside a movie theater the episode prior, which would not have been recorded as part of the Green Grove surveillance. The conversation involves Livia telling Junior that Tony reminded her of her cousin Kiki after she had her lobotomy.
Revealing mistake: When the shrink locks the door on Tony, they argue and she calls the police. When she finally calms down she approaches the door to unlock it but you can see the door move before she ever sticks a key in it or touches the knob. (00:25:20)
Revealing mistake: When Artie visits Livia at the hospital there is a close-up of the newspaper that Livia is reading and it is obviously fake. Some of the articles look like they have been pasted into it and there are white strips of paper covering up headlines or replacing them with new ones. (00:16:50)
