I have a follow up quest for the investigative report...........team. In "Return of the Jedi" when Vader is fighting Luke you can hear the faster regulated breathing, but when JEJ speaks the line, it is as though Vader has done nothing to exert himself. Since the whole double breathing issue came up this has kinda been nibbling at my mind. Thoughts anyone? I have a theory, but want to wait until others have weighed in.
