I think it's new. I don't think I missed it in
my previous analysis of the BSG Last Supper
image. Between Natalie/Tigh and Lee there is an area that moves much the way the now
color-matched pot of burning Kamala moves
in relation to Roslin. The Last Cylon is already in the image - it is just color-matched to the background - and it looks as if it is wearing a cloak - as seen in the Opera House visions. They will turn the image "on" when the show reveals the Last Cylon (over 9 months from now!) Go the the Sci-Fi.com/battlestar page, and after the Last Supper image loads, click on it to activate it, then scroll left and right and you can see the area that is distinct. To quote Miss Swan, "He looka like a man."
