Continuity mistake: At the start David is giving a speech about winning the primary. There is one point during a split screen where he grabs his microphone. However in the immediate next shot his hands are on the podium. (00:04:10)
Continuity mistake: After the tracker has been killed, we see Jack holding his handcuffs. Camera changes and his hand is not holding the cuffs any more. (00:40:20)
Continuity mistake: In the previous hour, Pattie has long straight hair down to her shoulders. We see this all the way through, even at the very end. Yet at the start of episode 22, when she is now at the party a mere 10 minutes later, her hair is very much shorter. There is no way she would be able to get ready for the party in that time, let alone have her hair cut.
Suggested correction: It's probable that Patty was wearing a wig during the party. It's normal for black women to own several wigs with different hairstyles and lengths.
