Wait, Bingowings-- are you pulling to have the audience NOT know the Grievous/Maul connection until the final Obi Wan battle?
If you are, I understand that would be a great moment.
I guess that's what I'm saying too-- although astute viewers who have seen the hints we're trying to add should be able to piece it together long before the "reveal".
I thought I wanted to have the audience know a lot sooner, but I hadn't really figured out how. Keeping the reveal until the final duel actually makes a lot of sense to me now.
