Hehehe. 😂 Good one, mech. 🙂
Well I would say that it will be a discovery on the jedi's part, perhaps accidental even. But remember in ep1 when Maul said "At last we shall reveal ourselves to the Jedi. At last we will have revenge" That didn't work too well, since Maul ended up at the bottom of one of George's shafts. So I say Palpy keeps himself pretty well hidden until he declares himself emporer.
Re: ?
I think Palpy will reveal himself to a very badly wounded Anakin. I saw an interview with George last night and there he talked about Vader. "He is more machine than man, but no humanity left, with mechanical legs and arms." Well we all saw Vaders hand, but mechanical legs. Guess poor old Anakin will be pretty worse of than I first imagined.
Anyway I think Palpy will seek out the injured Anakin and then lay it all out for him. Using the dark side of the force palpy will finish Anakin`s turn to the dark side, which will be easy towards the already weakened and betrayed soul of Anakin. Betrayed at least in Anakins mind.
