I was thinking one night about Vader's meditation chamber. This is completley a shot in the dark, but when Vader's helmet is being placed back on his head, there can be robot arms adjusting his mask and tubes coming out of his head. Then they all retract right before the helmet latches on. It's hard to explain, and probably harder for Ady to accomplish

I know this is an old subject, but seeing vader in his chamber remembering padme is... now that I think about it, a stupid idea considering he is more machine then man, and can't really think on his own at this point.

I dont know. Were you thinking about something in the chamber scene ADY?
