Either cut the Vader/Palpatine chat after episode 3 of the series, or directly put Jabiim before Mapuzo, which would imply that Vader let Obi Wan go as part of not loosing the “bigger picture” as Palpatine demanded.

After all, it would give Vader some character growth, like he’s learned his lesson and learnt to respect his former master, and solved his feeling on him, which eventually leads to finally being able to defeat him.

I’d use more ROTS material. I think that framing this series via the AOTC era flashback sort of diminishes Vader: puts him still in his Padawan place when clearly he was past that by ROTS.

But again, that’s Disney explaining how toxic-male-inmaturity is what makes Vader fail, etc…

Somehow, I’d look for making Vader closer to OT Vader with the existing material.
