I was rewatching ROTS on DVD recently and only just thought about something for the first time. When Darth Sidious is inducting Anakin into the Sith Order, he momentarily speaks in the archaic backwards dialogue of Master Yoda. Instead of "You will become a powerful Sith", which would be modern Basic, he says "A powerful Sith you will become", which is the more archaic and outdated form of speaking, allegedly. Does anyone have any theories about his choice of words here? Was he mocking Yoda's speech or do you suppose the ancient Sith spoke this way as well? We know that Palpatine was only 63 at the time, remember.
