Conversely, it is like the "light" side naming Luke and Leia in the birth scene. And it is rather "light", isn't it, the way Padme says them? This is not a bash of the acting; just an observation that the er, delivery, is considerably less drawn-out. It does feel, to me, that Padme has one part of her body in the physical realm, and another "up in the clouds", so to speak. Just as Sidious dips into the Dark Side with every smug fibre of his being, so the light is already shining back, glaring at him. An allusion to this is made at the beginning of the film, when the light from the star that bathes Coruscant momentarily blinds the viewer in the opening shot. Sidious, that Dark Side mutha, is going down.
