I think Obi-Wan getting the chance to shift Reva’s sense of failure into a redemption-esque moment is key to Obi-Wan not spiraling again, but I get removing it, as it would be jarring. Depending on how season 2 plays out, it might be something that could be used toward the beginning of a cut there, with her seeing the tracker as a post-credit stinger for this one.

I do wonder if the conversation Obi-Wan has with Owen about trusting the Lars family to take care of Luke should be retained, and possibly pushed toward the beginning, after Reva’s confrontation with Owen from Episode 1 (if that’s still in). It would be a major re-contextualization of the scene - he’s well aware that adventuring is a massive risk that he might not make it back from, so it becomes a decision made out of fear and worry of failure.

EDIT: Regarding the streamables for score changes, love what was done here, though I’d worry that the piano theme might clash with the scene at Mustafar featuring the regular Imperial March, which would come very soon after this scene if kept. I wonder if bits and pieces of the piano theme could be mixed in throughout the duel, intensifying when he speaks with Anakin’s voice, but only giving us the full payoff with the regular Imperial March.
