I'm starting to get a bit confused myself.

Essentially I received a list of words from Angel of characters, phrases and things that appeared in ANH, I'd post it on here but there wouldn't be much point as you could possibly figure it out yourself.

I think he is trying to provoke a rethink of what the sequels and prequels would have been like if we just used concepts in ANH as clues, like why does Artoo call Threepio a mindless philosopher when we don't really get much evidence of him philosophising ?

That could be worked in as being a PT era Threepio trait before his memory was erased.

Just one example.

I haven't a clue how that could be worked into the sequels to ANH but it might be a springboard for PT ideas.

Does that make sense?
