Lord Sidious thought about his new apprentice. So easy it was... he thought to himself. The boy didn't even know how his father became mine.
Sidious thought back to that fateful day. The Jedi thought Anakin Skywalker was the chosen one. He would destroy the Sith. Oh, if the Jedi could look at his cloned body now. Sidious smiled. Little did they know that this had been Sidious' plan from the beginning. Maul was pure rage, and Tyranus was the epitome of arrogance. Vader was potentially useful, but he had too many feelings.
The cloned bodies did have their problems. The accelerated aging meant a shorter lifespan. But that wasn't such a problem; he could just make another clone. He was now immortal, the embodiment of the dark side!
Sidious looked at young Skywalker. The child was perfect in every way: As powerful as Vader, without the restrictions. Skywalker could even call Sith lightning with his left hand, something Vader's prosthetics could never do.
Sidious knew the boy planned to kill him. All that would do would be to complete the boy's training as a Sith. Luke Skywalker would be the greatest Sith the galaxy had ever known, all the time believing he was still a Jedi!
