I swear to God, this happened, I was sitting in the lobby at Lucasfilm, waiting for [senior vice president] Kiri [Hart] to come out because I had forgotten my badge that day or something.
I picked it up and started thumbing through it, and I said, ‘Ooh, advanced Force powers.’
I was in the middle of trying to crack this whole thing with Luke and the ending.
I hadn’t quite got it yet, but I had this notion of what ended up being the projection thing that he does.
