As he lay dying, Vader ceased to be. Anakin Skywalker returned. He asked his son to remove the cumbersome, fearsome mask that had concealed his face for decades. His mask and life support removed, Anakin looked upon Luke for the first and last time. He then died, his body disappearing into the light side of the Force. Luke burned the dark armor that had encased Anakin's crippled body in a quiet funeral pyre on the forest moon of Endor that night.
I thought we were talking about Obi Wan and Maul. I agree with Ush.....Obi Wan was clearly using his anger after Qui Gonn was struck down. Maul was obviously unprepared for the death blow he received by the look of total shock on his face. I think Obi Wan, if he hadn't before, had acheived a new level of control in that duel.
