On the episode "Grievous Intrigue" of Season 2, you have Grievous delivering the line: "The story of Obi-Wan Kenobi ends here!" wich I think its a great line for him to say during the movie... but... that scene of the TV series might have too much noise and music.
I have to agree with Angel on the white staffs... i like them. It makes them feel like a more usual weapon, like a subsitute for lightsabers, but not as cool as lightsabers.
