Many questions are now answered.
1) Palpatine changes into Sidious the first time he uses Sith Lightning.
2) In the Senate, Palpatine uses the attack on himself by the Jedi as an excuse for his appearence.
3) The Jedi die in the following order: Saesee, Agen, Kit, Mace.
EDIT: About the dead Jedi:
The first two are dead in seconds. Kit has the coolest death knoll, imo.
EDIT: About Palpatine:
try something along the lines of: "Look at what those Jedi murderers did to me with their evil sorcery!'
The Senate goes beserk.
EDIT: More about Palpatine:
The Senate will have no trouble believing him. He has video evidence.
EDIT: A poster asked:
there was a quote where, Palpy says....
"Darth Plagieus was my master.....(his face comes out of the shadow and suddenly he is an old decrepid man) Before I killed him"
Motee can you explain this?
Anakin almost kills Sidious - TWICE. Sidious says that line to Anakin the first time.
EDIT: About Mace:
Anakin plays very little role in the Mace scene - bit he witnesses everything after Kit's Death.
EDIT: Tern on his source:
I now have 1 complete source. From the end of Utapau - Mace's death.
EDIT: More on Mace:
Mace's confrontation was set up by Sidious.
Sequence order:
Utapau, Anakin Vs. Sidious, Kashyyyk, Temple, Mace Vs. Sidious, Temple Massacre.
EDIT: Anakin quote:
"He can save Padme!" - Anakin.
