Continuity mistake: During the scene when Michael is attempting to deceive Brennen into letting him and Nate go (from the time Brennen receives the picture message to when Brennen leaves), Brennen's necktie (right below the knot) changes from having a dimple to being flat, 6 or 7 times during the scene.
Continuity mistake: In the episode "The Education of Jaime Sommers", when Jaime and Tom are having coffee, the size and position of cappucino foam on Jaime's nose changes from shot to shot.
Continuity mistake: In the very first episode, Josef mentions that Mick is ninety, and later on in the episode, he mentions that it's been sixty years since he felt the touch of another human being, or something like that, meaning he was turned in his thirties. Yet in episode three, I believe, he tells Beth that he'll be eighty-five in November.
