If the rumors about Leia being in the series are really true, I wish they could explain that scene of Leia remembering his true mother in Return of the Jedi. Maybe they could show Leia watching a hologram or something of Padmé “being beautiful, kind… And sad”. While restoring the canon, it could be a sweet scene.
I feel like this series has more chances to resolve the plot holes between PT and OT than to break canon (if done right). Except the line of Ben telling Luke that “Obi-Wan” is a name he doesn’t hear since before Luke was born. I don’t know how they could resolve this, since in Revenge of the Sith he is called “Obi-Wan” the entire movie.
