I suppose you could have Yoda learn the truth, which is something we wouldn't necessarily see in the movie, but he could tell Obi-Wan about it later. Maybe.
I was approaching this question as if the first two movies and the original trilogy don't change. I just want to see what would need to be done in episode III in order to make it continitous. Since Obi-Wan admits that he lied and why, all we need to do is explain that one line "once a pupil of mine." That is the only thing that I can see keeping the ideas that Darth Simon and I put out from being possible.
I agree that Leia's parentage should also be kept a surprise.
I'm still thinking of a way to get wround that one line...
Stay tuned for the next puzzle
