When Tarkin discovers that the rebels have gained access to the cell block corridor, Vader says "They must be attempting to return the stolen plans to the Princess, she may yet be some use to us." I was thinking about lines of dialog that don't make any sense (like threepio saying there'll be no escape for the princess this time, which you've cut), that maybe it would improve the film if Vader didn't make such a stupid assumption. I checked your first post and this change isn't there, but if you're looking for some of those silly little lines/scenes to cut, that could be one.
