Apologies if this has been brought up before, but something that has bothered me about ROTS relates back to a line from ROTJ: "Obi-wan once thought as you do." And yet, from what we see in ROTS, it almost seems as if this line should be: "Your mother once thought as you do"....Now, it might be easier to change the line in ROTJ, but that seems a bit backwards. Is there any way to give Obi-wan some (temporary) optimism about Anakin's redeemability? I could imagine even a single line, like "Anakin, there is still good in you!" before the duel on Mustafar...but that might require an impersonator's ADR...
