I dont think Anakin would be able to kill Dooku! He was nothing compared to Dooku! Yoda had a hard time with him! The series is not what you think. Why are the Jedi in hiding? That is the greatest puzzle?
I dont think Padme every leaves the Republic, I think she would die first. She has Luke and Leia by Dooku.Padme finnaly dies. They are stolen by Anakin out of his love of Padme. Renamed and hidden in places Anakin knows. He dies and IV starts.
My guess.
Star Wars canon says Anakin is Vader. That's the whole story arc. Pay attention.
Anakin will duel with Obi-Wan and, horribly disfigured, be left for dead. He will be saved and rehabilitated by the Sith. He will assume the new identity of Vader.
This is according to starwars.com and other official sources. It is Star Wars canon - you speak heresy, blasphemer.
