Re: New Star Wars animated show "Rebels" coming fall 2014
Until we see him in one of the unreleased "Season 6" arcs the only images of Sifo-Dyas are from, I believe, a graphic novel or two that depict some of his interactions with Dooku around the beginning of the clone project and thus shortly after the events of Episode I, before the Separatist movement ever began.
Human instinct is pretty strong. You can't expect us to change overnight.
