Originally posted by TrocityPalpatine believed him to be dead. That would show his knowledge of the force was pathetic in direct comparison to Plagueis. Palpatine wielded the might of a galaxy but guess what he moronically risked it all to recruit Vader's son meanwhile Plagueis rose to power. Sidious already acknowledged his master was more powerful and knowledgeable than he was.
I think Snoke is Plagueis but to say that undermines Sidious' entire reign is laughable.You could just make the claim that Snoke was too afraid to reveal himself again until well after Sidious was gone.
