what if anakin keeps on having dreams of being murdered by Vader? perhaps that is what he is chasing enstead of padmes death, or maybe he sees vader kill her too, and then slay an epIII aged obiwan, then slay a baby.

could be in that weird slow motion like the cave on dagoba

That could work, it would certainly blur the line between Vader and Anakin but only if it was done ESB style and not in the ROTS style.

We could just see a darkened gloved hand and hear Padme call out for Anakin as she gasped for breath but then we have the problem of why is she there if not try to save her husband (she could still be trying to do that but it would have to be something that only clicked into place for the first time viewer when they watched ESB)?

Perhaps the Seperatists contacted her to beg for an armistice (Nute Gunray can be over-dubbed) only to be killed by Darth Vader before she gets there.
