He tells him he knows of his origins, of the snowy village on Dathomir where he was plucked as a youngster to become a servant of the dark side. Maul grows angry. With Pre Vizsla's darksaber, he runs Satine through, and she declares her love for Kenobi in her dying breath. Savage asks if they are to kill Kenobi, but Maul would rather he drown in sorrow and misery in a prison cell.
On Coruscant, in the executive offices of the Supreme Chancellor, Palpatine senses a disturbance in the Force. He summons his shuttle.
As the super commandos escort Obi-Wan back to prison, they are suddenly ambushed by Bo-Katan and the Mandalorian rebels. Bo-Katan returns Obi-Wan's lightsaber, and offers him a jetpack. Kenobi joins her in blasting off away from the prison platform.
A Republic executive shuttle arrives at Sundari, and from it emerges the robed and hooded form of Darth Sidious. Mandalorian super commandos try to intercept him, but Sidious easily uses the Force to strangle them.
Bo-Katan and her rebels are pursued through the Sundari cityscape. Obi-Wan and Bo-Katan fight side-by-side. More and more of Sundari is being blackened by war.
In the throne room, Maul senses a presence he has not felt in over a decade: that of his old Master. Sidious enters the throne room, easily choking the super commando guards to death. Seeing Sidious, Maul declares all his effort in empire-building an attempt to return to Sidious' side.
Sidious sees through Maul's lies -- he views the Zabrak not as an apprentice, but as a rival to be destroyed. Maul pins both Sith brothers with a Force push. Savage and Maul ignites their lightsabers, and Sidious, too, ignites two lightsabers to do battle with these would-be Sith usurpers.
In the city, the Mandalorian civil war continues. Obi-Wan and Bo-Katan fight their way to a gauntlet fighter. Bo-Katan tells Obi-Wan to return to the Republic and tell the Senate what has happened here. Obi-Wan warns this would likely lead to a Republic invasion, but Bo-Katan accepts that as a price worth paying for the death of Maul. Kenobi realizes that Bo-Katan is the sister that Satine spoke of earlier.
Meanwhile, Sidious duels the Sith brothers, never wavering from his position of superiority. Fueled by the dark side, Sidious is transformed into an agile, whirlwind of destruction. He strikes down Savage, killing the monstrous Nightbrother.
As Savage's life fades, Mother Talzin's dark enchantments fade away in clouds of green mist, and Savage returns to his smaller, natural form. He apologizes to his brother, recognizing that he was never like Maul, never capable of truly being a Sith.
Maul attempts to avenge his brother's death, but he simply cannot defeat Sidious' power. Sidious disarms his former apprentice, batters him with Force pushes, and inundates him with Sith lighting. Sidious cackles with glee as he tortures Maul. He cryptically notes that he does not intend to kill Maul. No, Sidious has other uses for the defeated Sith Lord.
