It's unknown at this time, but there are multiple hints which people interpreted as Supreme Leader Snoke being Plagieis. РІР‚СљItРІР‚в„ўs ironic that he could save others from death, but not himself.РІР‚Сњ Disney Episode VII canon: РІР‚СљUnfortunately, he taught his apprentice everything he knew-and then the apprentice killed him in his sleep.РІР‚Сњ Palpatine smiled slightly. Typically, Wrede's Junior Novelization is even more condensed: РІР‚СљSo,РІР‚Сњ Anakin murmured, РІР‚СљitРІР‚в„ўs only a tragedy for Plagueis-for the apprentice, the legend has a happy ending РІР‚В¦РІР‚Сњ He goes on to become the greatest Dark Lord the Sith have ever known РІР‚В¦РІР‚Сњ РІР‚СљWhat about the apprentice? What happens to him?РІР‚Сњ ThatРІР‚в„ўs the tragic irony, you see: he can save anyone in the galaxy from death-except himself.РІР‚Сњ РІР‚СљAnd his apprentice kills him in his sleep,РІР‚Сњ Palpatine said with a careless shrug. РІР‚СљWell, to safeguard his powerРІР‚в„ўs existence, he teaches the path toward it to his apprentice.РІР‚Сњ Once he has gained this ultimate power, he has nothing to fear save losing it-thatРІР‚в„ўs why the Jedi Council brought him to mind, you know.РІР‚Сњ РІР‚СљOh, well, it is a tragedy, after all, you know. Matthew Stover's RotS novelization doesn't offer anything earth-shatteringly new over the film: All we know is 100% contained in Sidious' words to Anakin, and as you wisely noted, there's nothing to stop him from telling the truth 'from a certain point of view', to use Obi-Wan's terminology. This info largely cloned from my earlier to Snoke/Plagueis question Disney Pre-Episode VII canon: Pablo Hidalgo I said Sidious killed Plagueis. Is he actually dead or does Sidious think he's dead? Pablo Hidalgo May Sidious killed Plagueis. Witka May my real question to put it to rest, is did Plagueis' spirit survive physical death through the dark side? Hidalgo he was said to possess the ability to keep loved ones from dying. Pablo Hidalgo Plagueis was killed by his apprentice. Witka Apr Can you confirm that Snoke is NOT Plagueis? Can you confirm that Plagueis is dead? Pablo Hidalgo on Twitter just confirmed that Snoke isn't Plagueis (or rather, that Plagueis 'truly, deeply' died. The only caveat is that - at least in early 2016 - his twitter account had an explicit note that the twitter feed is NOT to be considered a canonical source. Pablo Hidalgo (LucasFilm's and then Disney's canon expert, high level employee and creative mind) conclusively confirmed the fact on his Twitter account.
