I really like the idea of having Vader say, “Your mother once thought as you do.” This change makes sense, and not coming from a PT standpoint either. It’ll help his character be more dynamic; Vader would originally bring up Obi-Wan too often (“Obi-Wan has taught you well”, “Obi-Wan this”, “Obi-Wan that”), so for the audience to see that he actually remembers someone else in his past life makes him even more compelling. Hopefully it can be done 😃
