I think that master syfa-dias was in fact a jedi all along and was probably tricked or forced into ordering the clones by dooku ten years ago. He was probably told that a jedi would be used as the basis for the clones and that is why he agreed to do it but was killed by dooku before he could select a subject. At that point, dooku chose jango fett to be the subject at the request of sidious.
This would explain the the look on windu and yoda when obiwan mentions syfa-dias. They maybe know there was a duel between dooku and dias and that dooku won it. Maybe they have always wondered why they fought each other and the answer has become clear to them. This would also explain why dooku has been banished form the jedi order and is on geonosis. (He has been banished because he killed another jedi).
Sidious has been keeping tabs on the clones during the ten years through jango fett and then dooku but his plan goes tits up when the jedi discover the clones and yoda uses them for the good guys.
What do you guys think???
Storywise, the Sifo-Dyas idea has to be tied up or explained in Ep3. I've only seen AOTC once but are these the facts? Correct me if I'm wrong:
1. The Jedi think Dooku left for political reasons. Kai Adi- Mundi calls him a "political idealist" and Mace refuses to believe that he is trying to kill Padme. Mace still considers Dooku a Jedi.
2. After TPM, Sidious ditched the trade federation.
3. The Trade Federation went to Dooku for help.
4. Dooku is secretly "Darth Tyrannus" and Sidious' new apprentice. So the Trade Federation are still being controlled by Sidious' though they don't know it.
5. Dooku and Sidious are trying to start a war.
6. Jango was hired by "Tyrranus". He doesn't know it's Dooku. Or does he?
7. The Clones were ordered by a Jedi called Sifo-Dyas.
8. The Kaminoans (spe) think they are doing it for the Jedi.
9. The Jedi don't know about it.
10. Sifo-Dyas died 10 years before AOTC. This doesn't mean the clones weren't ordered well before then.
11. Obi-Wan has heard of Sifo-Dyas but doesn't know him. He wasn't even sure if he was dead.
12. Yoda and Mace know Sifo-Dyas.
13. A Jedi erased Kamino from the archives. Presumably it was Sifo-Dyas.
So are we trying to work out who Sifo-Dyas was and what happened to him?
Well...
6. That depends whether he actually met Tyrannus when he was hired. If he did, then there is no way he can not know that Tyrnanus is Dooku.
10. No, it is specified that the order was placed almost ten years ago.
11. Obi-Wan was as sure as he could be that Sifo-Dyas was dead, but it was only sensible to double check.
And yes to both your questions!
First of all, the Maul is Sifo Dyas theory is ... IMPOSSIBLE. No ways guys ... get real !
Secondly ... the theory that Sifo Dyas secretely ordered the clones, and then died ( or was killed ) is one explanation that is atleast theoretically possible ... but ... I feel that there is much more to it than that ...
It's just too many conincidences, as Ush says ... firstly the similarity between Sifo Dyas and Sideous ... the shifty glances of Yoda and Windu at the mention of his name by Obi Wan .....
lemmee think, lemmee think .....
