It's a mistake.
They have Anna, AJ, and Bess listed in the incorrect spot. All three should be under 'Series Regulars'. Besides, if Anna/Lindsay wasn't part of the main cast, she wouldn't have such a heavy storyline for 4x06.
Not necessarily--Adam had a pretty big role in "Snow Day" and Sid factored prominently in "The Ride In."
It could very well be a mistake, but it could also be that AJ's promotion was to recurring and not series regular. As a recurring reg, he would still be in every episode, just not getting top billing. Wasn't that how Eric Szmanda's promotion worked in CSI? He was a recurring reg after season one, but when did he make the main credits.
Is Bess currently slated to be in any episodes other than the first thus far? My impression was she would be like Detective Angell, who shows up every now and then but isn't in every episode. I guess we'll see!
