Supreme leader Snoke is the father of anakin
Darth Plagueis was a Dark Lord of the Sith so powerful and so wise, he could use the Force to influence the midi-chlorians to create life. He had such a knowledge of the dark side, he could even keep the ones he cared about from dying.
Yoda: Master Qui-Gon. More to say have you?
Qui-Gon Jinn: With your permission, my master, I have encountered a vergence in the Force.
Yoda: A vergence, you say?
Mace Windu: Located around a person?
Qui-Gon Jinn: A boy. His cells have the highest concentration of midi-chlorians I have seen in a life-form. It was possible he was concieved by the midi-chlorians.
Mace Windu: You refer to the prophecy of The One who will bring balance to the Force. You believe it's this boy?
So Star Wars VII is out and it has a new master of the siths the supreme leader Snoke.
What about if this leader darth plagueis , darth plagueis could make life out of midi-chlorians so it's supposed that he died but he might not.
This would explain why they have the helmet of darth Vader and why he trained Kylo Ren and its searching for his grandson Luke Skywalker
