When I edited this cut of the Kenobi series I did so with the original trilogy in mind.
From watching the OT I never got the idea that Lea knew she was adopted when growing up, probably because George came up with the idea of Luke and Lea being twins when he did ROTJ 😊. When Bail takes Lea to look after at the end of ROTS I always figured he and his wife would raise her as their own child, and only they would know that she wasn’t. That would serve as a much better cover. To me the way the writers went with it in the Obi Wan series didn’t make much sense. This is of course just my opinion but that’s why I cut all the talk about Lea’s real parents.
I think expounding on Leia’s feelings about being adopted help the OT. Originally when Luke asks Leia about her real mother in ROTJ it comes completely out of left field. But establishing that she knows early on helps to smooth that out. And Leia looks nothing like Bail or Breha so hiding that she was adopted would never have worked.
