Do you worry about not seeing the Pope Pius XII in every World War II movie?

Yoda in ESB is nothing like Yoda in the PT.

He get's a lot of mentions so you don't have to see him (just as the Emperor's absence in ANH isn't a major issue).

It's a challenge because he is so many scenes but it is the Radical Redux Thread.

I mentioned it because it would be a challenge (just like keeping the ESB Vader reveal a surprise which also a near impossible challenge but may yield interesting results if thought was given to how it might be done).
