I've been thinking when Luke is taken via a platform to see Vader the trip is longer and more drawn out than shown, it's just shortened for us.

What confuses me about that though is that Luke would have had to go along the arm of the vane to get a platform to take him to the carbon chamber if it is indeed in the wind vane structure and we only see him in the Cloud City interior and only see the vane exterior after Luke goes out the window.

Maybe I am looking too deep into this but it just confuses the hell out of me that that is where the carbon chamber is given where we see Luke going through the interior door and then popping up in the chamber apparently in the vane.
