The following is a summation of Anakin's turn as originally written and filmed:*Palpatine reveals his true identity to Anakin, telling him that the Jedi are planning to take over the Republic and to accept the Sith and the darkside. Anakin is conflicted but distrusts the Jedi--his mind is being influenced by the darkside already and he chooses to stay with Palpatine, essentially accepting the Sith in this scene. Mace and the Jedi then enter Palpatine's office--with Anakin present beside Palpatine. Mace tells Anakin to get behind him but Anakin remains where he is. When the Jedi ignite their lightsabers to arrest him, Palpatine uses the Force to retrieve Anakin's lightsaber and the fight begins. Anakin watches as his two mentors fight, and as Palpatine is disarmed he unleashes the Force-lightning. Mace and Palpatine struggle, and Palpatine's face is drained of his visage in the effort to sustain the lightning. Finally, as the two masters remain locked in a standstill, Anakin cuts off Mace's hand, and Palpatine fries him and sends him out the window. Anakin collapses in disbelief that the Jedi were indeed attempting to take over the Republic, and Sidious knights him, telling him to go kill the rest of the Jedi before they retaliate.
