General Grievous speaks with Darth Sideous/Anakin's nightmare

This is the scene where Grievous talks to Darth Sideous and Anakin's Nightmare takes place in Ryan's and Meg's Adventures of Star Wars Episode III: Revenge of the Sith.

[We see a ship flying in space to a planet Utapua. The ship flies and it lands on a dock bay and when the doors on the back of the ship open, General Grievous comes out. He heads up to the communications room and then after a little cough, contacts Darth Sidious]

General Grievous: Yes, Lord Sideous?

Darth Sideous: (hologram) General Grievous, I suggest you move the Separatist Leaders to Mustafar.

General Grievous: It will be done, my lord.

Darth Sideous: (hologram) The end of the war is near, General.

General Grievous: But, the loss of Count Dooku...

Darth Sideous (hologram): His death was a necessary loss. Soon, I will have a new apprentice, one far younger and more powerful.
