How recent is that pic? Did they replace the pic with a new one with an actor other than the one being pointed to as Pa Patrelli? That doesn't look much like him and I am sure I've seen an episode where the pic they showed had Pa Patrelli clearly shown, and facing forward, IIRC.
Anyway, are there two more company members, the women on the left, who are yet to be utilized in the show? Is there anyone else down in front on the right obscured by the hand?
i think Pa Petrelli was always facing sideways (i think, but I could be wrong).
Also, the front row should have 4 people, as I think there are 12 total. So (left to right) it's the woman, then Charles (the guy who died in season 1 under peter's care) and two others (or at least one other, I recall a hispanic looking man).
