theres a poster that i have seen somewhere, i think it may even be fan art. it depicts the emperor almost blessing a kneeling vader, by placing his helmet on his head. it almost looks medieval.

i would have loved to have seen vader revealed this way.

maybe vader limps off the table without his helmet, looking uncomforatble with his face weezing, he then drops to his knees, slowly rising from weakness to submission. the emperor then approaches the newly created monster, and lowers the helmet onto his head, knighting him. maybe this could be the point where he announces him as darth vader.
