That and a very subtle tweak when we see the Vader helmet to hint at the Emperor’s theme.
I don’t plan to do anything else about it. I’m okay with it being that way, as any left turn hints would maybe feel weird and sort of weirdly anachronistic. It’s like the OT having twists that have dubious retroactive buildup. I dunno. But I’m okay with TFA like we got it. It and TLJ have a couple subtle hints that weren’t there before.
