Master Sifo-Dyas- a bit of a mystery (SPOILERS)
Okidokey, they clearly inserted this one in to give us something to think about. To summarise:
1. Sifo-Dyas placed the order for the clones (or at least, the Kaminoans say so)
2. He was a Jedi Master who died just UNDER ten years ago (presumably, therefore, he died just after TPM)
3. Sifo-Dyas can obviously be corrupted to Sidious, though that would be an unprecendented way of choosing your Sith name as Dooku is nothing like Tyrannus
4. But there must be SOME dodgy connection there because Jango, sent as the template to construct the clones that Sifo-Dyas ordered, never met (or so he says) Sifo-Dyas, having been recruited by Tyrannus.
So, are we to assume, perhaps, that Sidious' cover was as a great Jedi Master who then faked his death soon after TPM? Maybe because being Supreme Chancellor took up too much of his time. But could he possibly have managed being a Senator and importnt Jedi at the same time?
Or is Sifo-Dyas nothing to do with Sidious at all, in which case, what exactly is the deal here?
