I think that's a scene that could work and needs to be in. Though the "difference" (in order not-to give the "overused" feeling) should be in the music. We have to find some piece of score that is dark, but not dramatic nor menacing.

In ESB is like "look, he's cold as shit, he just kills everyone who doesn't deliver properly" + menacing music. It's just about showing how badass Vader is.

ROTJ, which by definition is more focused on Vader's persona, and by this it could comprehend "why" he's so badass, could be either:

a) He chokes jerjerrod with rage, because he feels between the hammer and the anvil, so we should use some "rage, hurried music". (ROTS coral music, when grievous lands in Utapau comes to mind).

b) He kills with disdain. More in "who's this shit to interpose betwee the emperor and me?"... like Yoda does to the Royal Guard in ROTS too.

Either A or B, I think that ROTJ scenes where Vader is really hard-edge Vader don't abound and we should use it, albeit making some detail (since it's a not very trascendental scene, music is a "detail" and not a really important component of the scene) different.

I could read your scripts for this couple of mounths, I have some time until april.
