Hooragh, i finally get what your talking about now ImperalFighter! :-)

I really do like that suggestion there Bingowings. It also confirms, on a third level, Ben's warning about being seduced by the dark side when leaving dagobah, as if to warning to Luke about being "power hungry" inside, like his father was (unknown to Luke at that time). May also add to the line "join us, and we can rule galaxy, as father and son", as Vader can teach Luke more than what any Jedi can, as an ironic nod towards Anakins demise in episode 3 (incidently, with George spouting on about revolving story lines, and baby Anakins clorine count being off the charts, i was almost convinced Palps was Annies prodical papa somewhere in the prequels, just to give us that same shock value as the reveal in empire-but NO!).

I remember Jambe pasting together samples by James Earl Jones together from his other movies to make Vader say what he wanted him to say, for a project if im not mistaken.
