Continuity mistake: We see Jack and Nina on the escalator and the people ahead of them get off at the top, camera changes to a shot from the top of the escalator and we see the previous 2 people getting off again. (00:21:00)
Continuity mistake: We see a black car driving down the street after the end of the scene between the two Palmers. In this shot you can see the passenger in the back of the car (Andre) is not on the phone. Camera changes to inside and Andre is on the phone. (00:15:50)
Continuity mistake: When Tony and Mason are having words about things being personal, there is one point where Mason approaches Tony and Tony's arms go from on his hips to down by his side instantly. (00:13:10)
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
