I believe all these issues about the hallway scene are all to do with context.

People say why didn’t Vader do all these brutish or powerful things with Luke? Simple, respect, of course: He wanted Luke to feel challenged, he didn’t want to humiliate his son, he wanted to tempt him.

Why didn’t Vader cut down everyone on Hoth? They had already lost, he was there to pick up the pieces.

We do not know the original context of the Tantive IV in Star Wars. We do know it was being chased by a Star Destroyer, with RO now concrete, we have a context. Leia claiming to know nothing has always been obvious stalling. If they were in no trouble why were they having a shootout with the Empire and not cooperating, now it’s just even more obvious now we know they came direct from the battle.
