Luke's demeanor/personality/way of speaking in ROTJ
I'd previously mentioned how I thought it would be interesting to see how Han (during or just post ROTJ) reacted to the difference in Luke from when he last saw him.
I've thought about Luke's more formal way of speaking, sometimes under-reacting emotionally and such.
The thing is that for a large part of ROTJ, Luke is, himself, performing. His speech to Jabba is certainly rehearsed/scripted. The one one for Vader and the Emperor has to be at least somewhat planned. Even on the bridge with Leia, it was definitely not "off the cuff." Though one could argue planning more its own change.
The conversation with Yoda is more "natural" - less structured/planned. And with Obi-Wan (Luke wasn't exactly fond of the "certain point of view" defense).
Anyway, I was just curious as to the degree others think his long-term speech patterns (and demeanor, but I was really thinking of of his way speaking, slang, etc.) change before and after ESB, and how they are in the years following ROTJ, etc.
