I guess my question regarding how Adywan (or anyone) plans to keep Vader’s reveal a secret with that one line in ANH (and as others have brought up, a lot more is there) is what started this.

I think a better story can be told if you’re not dancing around keeping things hidden for a reveal later. However whatever Adywan decides, I wish him the best - he’s already given me more with the OT than I ever could have expected… It’ll be near impossible for him to make the prequels worse, so I’m not too worried… 😉
