Something I think ROTJ benefits from is removing the whole Jealousy of Han... Let's face it, Leia frees him from Carbonite tells him she loves him and put's her own life in grave danger to get her man back. Han continuing to question weather or not she still fancies Luke is a drag and diminishes what we have seen previously.

I also re-watched J Davdar Building Empire again recently and thought about the restored dialogue of Leia in the falcon. "we've got to go back" and again "we've got to go Back" said with more authority over riding Lando's excuses about not going back.

"I know where Luke is" although it's an admission and explanation to why she want's to go back. As viewers of the film we don't need that explanation we know she knows where Luke is and I think it once again slightly out of character that although Lando has helped get them out of trouble he now seems only bothered to save his own skin or simply does not think about their freind Luke. So After he rescues Luke from on top of the Falcon then I think the group can accept him more that he is not such a bad guy and was in a awkward predicament and does not just care about himself but does really care about others also. Leia does not know him at all where Chewie and Lando have a bit of History probably why Chewie never killed him out right.

I like Leia Being dominant at the end of the film, I think at adds much more to her this line that she still has not accepted Lando fully.
