Snoke: We don’t know who he is, but we can tell you who he ain’t.
Who is Snoke? Is the question that all Star Wars fans asked after watching The Force Awakens. Well, according to Pablo Hidalgo, of Lucasfilm’s Star Wars Story Group and the man in charge of maintaining the canon,”Snoke is Snoke,”
Hidalgo is apparently getting a bit sick of the popular fan theory that Snoke is actually Darth Plagueis, the master of Emperor Palpatine.
“His apprentice [Palpatine] killed him,” Hidalgo said. “Sidious killed Plagueis. Ascending to master. As is the way of the Sith.” and “I said Sidious killed Plagueis. He killed him. Killed. As in “to kill”. Like, there was killing.”
We can’t really get much clearer than that, can we? No matter who Snoke is, he’s not Plagueis.
